1. Module 1 — Embryology and Congenital Anatomy
[Verse 1]
In the fourth week, a tube begins to form
Foregut suspended, dorsal and ventral, caught between two storms
The mesogastrium stretches like a veil
Dorsal drapes toward the spleen, ventral toward the liver trail
The stomach is a compass, hasn't found its north
Until rotation grabs it, pulls the greater curvature forth
Ninety degrees clockwise, longitudinal the axis spins
The greater curvature drifts left, and that is where the mystery begins
The left vagus nerve — it rode the anterior wall
So when the stomach twisted, left fibers took that hall
Now the anterior vagal trunk carries left-sided grace
With hepatic branches reaching up into their proper place
[Chorus]
Left becomes anterior, right fades to the back
Clockwise on the longitude, the pylorus swings and tracks
Greater omentum billowing, the lesser sac sealed in
Dorsal mesogastrium — where the spleen was born within
Left vagus, hepatic branches, anterior wall
Rotate the sequence, draw it out, you'll remember all
[Verse 2]
Then the anteroposterior axis takes its turn
The pylorus swings rightward and cephalad — a crucial burn
The cardia drifts left and caudal, settling into place
The duodenum traces out its C-loop, carved in space
That C-loop presses retroperitoneal, fixed against the wall
The ligament of Treitz suspends the junction standing tall — no, anchors it in place where surgeons make their call
[Chorus]
Left becomes anterior, right fades to the back
Clockwise on the longitude, the pylorus swings and tracks
Greater omentum billowing, the lesser sac sealed in
Dorsal mesogastrium — where the spleen was born within
Left vagus, hepatic branches, anterior wall
Rotate the sequence, draw it out, you'll remember all
[Bridge]
Omental bursa hidden like a whispered fold
The gastrosplenic ligament keeps its secrets cold
Gastrophrenic tethers cardia up above
The greater omentum drapes like something left unloved
And in the dorsal mesogastrium, quiet, dense, and dark
The splenic anlage condenses — budding from that arc
[Verse 3]
When rotation stalls or fixation fails to hold
The anatomy rewrites itself in consequences bold
Situs inversus flips the mirror, stomach swings to right
The surgeon at the table recalibrates the site
Gastric duplication cysts — posterior fundus, near the GE zone
Microgastria leaves a tube too narrow, standing alone
Antral webs obstruct the exit, atresia seals it through
Diverticula pocket at the fundus, posterior in view
[Chorus]
Left becomes anterior, right fades to the back
Clockwise on the longitude, the pylorus swings and tracks
Greater omentum billowing, the lesser sac sealed in
Dorsal mesogastrium — where the spleen was born within
Left vagus, hepatic branches, anterior wall
Rotate the sequence, draw it out, you'll remember all
[Outro]
Draw the axis, mark the degrees, trace the vagal thread
The anterior trunk is left-born — carry that instead
Foregut gives the stomach, mesogastrium gives the sac
Rotation wrote the anatomy — now trace your way back
2. Module 2 — Gross Anatomy and Peritoneal Relations
[Verse 1]
From the cardia down where the esophagus drops,
The angle of His cuts a notch where the Z-line stops,
Phrenoesophageal membrane holds the hiatus tight,
Left crus of the diaphragm bracing on the right.
Fundus domes above, then the body sweeps long,
Incisura angularis — that notch on the lesser curve belongs,
Antrum narrows down to where the pylorus stands,
And the vein of Mayo marks it plain as an outstretched hand.
[Chorus]
Cardia, fundus, body, antrum, pylorus in line,
Lesser curve and greater curve define the design,
Gastrohepatic, gastrocolic, gastrosplenic — name your plane,
Open the lesser sac and read the posterior wall again,
Pancreas, splenic vessels, left kidney behind,
Transverse mesocolon — six structures, six signs.
[Verse 2]
The lesser omentum hangs from the hepatoduodenal gate,
Pars flaccida — thin and soft, pars condensa holds the weight,
Watch the aberrant left hepatic artery hiding in that fold,
Cut it without caution and your liver runs cold.
Gastrocolic ligament — your avascular working door,
Pull it wide and easy, you're walking the lesser sac floor,
Gastrosplenic carries the short gastrics along the spleen,
Gastrophrenic anchors high where the fundus leans.
[Chorus]
Cardia, fundus, body, antrum, pylorus in line,
Lesser curve and greater curve define the design,
Gastrohepatic, gastrocolic, gastrosplenic — name your plane,
Open the lesser sac and read the posterior wall again,
Pancreas, splenic vessels, left kidney behind,
Transverse mesocolon — six structures, six signs.
[Bridge]
Now the stomach bed — press your palm against the back,
Pancreas laid flat across that retroperitoneal track,
Splenic artery coiling, splenic vein running straight,
Left adrenal, left kidney sitting quiet at the gate,
Diaphragm above, spleen tucked to the left side,
Transverse mesocolon — the inferior relation, don't misguide,
Colonic injury waits for surgeons who forget that floor,
So name it, trace it, know it cold before you cut and explore.
[Verse 3]
Four coats from lumen out — and the order matters here,
Mucosa first, then submucosa, that's the layer surgeons revere,
Submucosa holds your sutures when the others tend to tear,
Muscularis runs oblique, then circular, then square.
Oblique fibers sling the fundus, circular guards the pyloric gate,
Longitudinal wraps the outside — three-ply weight,
Serosa seals it all except two bare strips along the curves,
Where ligaments attach and the peritoneum swerves.
[Chorus]
Cardia, fundus, body, antrum, pylorus in line,
Lesser curve and greater curve define the design,
Gastrohepatic, gastrocolic, gastrosplenic — name your plane,
Open the lesser sac and read the posterior wall again,
Pancreas, splenic vessels, left kidney behind,
Transverse mesocolon — six structures, six signs.
3. Module 3 — Vascular Anatomy, Lymphatics, and Variants
[Verse 1]
Celiac trunk splits three ways off the aorta's chest
Left gastric, common hepatic, splenic — carved and pressed
Left gastric climbs the lesser curve, sends a branch up high
Esophageal ascending — tracing where the vessels lie
Right gastric from the proper hepatic, sometimes common, sometimes GDA
Both arteries converging where the lesser curvature holds sway
Gastroduodenal drops behind the duodenum's wall
Posterior ulcer erodes it — that's a hemorrhage call
[Chorus]
Celiac to left gastric, hepatic, splenic — three
Map the variants or the patient bleeds on thee
Station one through twelve, fourteen-v, sixteen
D1 and D2 — know the nodal scene
Replaced left hepatic — gastrohepatic ligament, feel
Before you cut that tissue, check what's real
[Verse 2]
Greater curvature gets rich — right gastroepiploic from GDA
Left gastroepiploic from the splenic, feeding from the other way
Short gastrics branch from hilar vessels, five or six or four
Posterior gastric from the splenic — half of patients carry more
The submucosal network anastomoses wall to wall
That's why conduit surgeons harvest stomach — tolerates the haul
Embolization works because the collaterals compensate
Devascularize extensively — the stomach holds its fate
[Chorus]
Celiac to left gastric, hepatic, splenic — three
Map the variants or the patient bleeds on thee
Station one through twelve, fourteen-v, sixteen
D1 and D2 — know the nodal scene
Replaced left hepatic — gastrohepatic ligament, feel
Before you cut that tissue, check what's real
[Verse 3]
Replaced left hepatic from left gastric — fifteen to twenty percent
It runs inside the gastrohepatic ligament before you dissect
Replaced right hepatic from the SMA — posterolateral placement found
Wrapping round the portal vein in the hepatoduodenal ground
Common hepatic off the SMA — celiac stenosis too
Median arcuate ligament compressing — GDA supplies the view
Hepatic flow depends on GDA when celiac can't perfuse
Clamp that artery carelessly and hepatic function you will lose
[Bridge]
Venous drainage — coronary vein to portal, right and left gastric flow
Right gastroepiploic joins the gastrocolic trunk below
Into the SMV through Henle's trunk — remember how it goes
Short gastrics and left gastroepiploic drain to splenic as it flows
Splenic vein thrombosis — sinistral hypertension, left-side only
Varices form at the cardia where portosystemic paths get lonely
4. Module 4 — Innervation
[Verse 1]
Left vagal trunk rolls anterior, hepatic branches peel away
Feeding bile decisions, liver traffic every day
Then the nerve of Latarjet runs the lesser curve down south
Crow's foot fanning at the antrum, five toes spread toward the mouth
Acid cells above that crow's foot, antral motor fibers low
Cut above to spare the pylorus — that's the selective window
[Chorus]
Vagus, vagus, two trunks at the hiatus
Anterior left, posterior right, don't you confuse 'em at the table
Criminal nerve of Grassi hides up high behind the crus
Miss that fiber, ulcer's back — recurrence coming back to you
Crow's foot, celiac, Latarjet — draw the map before you sever
Confirm your cut, sweep the hiatus, parietal cell vagotomy forever
[Verse 2]
Now the right trunk drops posterior, celiac branch first to split
Feeds the solar plexus ganglia, sympathetics benefit
Then posterior Latarjet mirrors left along the curve
But buried high and posterior, Grassi's the criminal nerve
Arises before the trunk descends — most surgeons miss the spot
Sweep behind the esophagus or leave that fiber hot
[Chorus]
Vagus, vagus, two trunks at the hiatus
Anterior left, posterior right, don't you confuse 'em at the table
Criminal nerve of Grassi hides up high behind the crus
Miss that fiber, ulcer's back — recurrence coming back to you
Crow's foot, celiac, Latarjet — draw the map before you sever
Confirm your cut, sweep the hiatus, parietal cell vagotomy forever
[Verse 3]
Truncal vagotomy — blunt axe, kills the whole supply
Antrum loses motor rhythm, pylorus won't comply
So you drain it — pyloroplasty opens what the nerve controlled
Without that drainage, gastric stasis, food pools, patient cold
Selective spares the hepatic branch, celiac off the hook
Highly selective — just the parietal cells, go page the textbook
[Bridge]
Greater splanchnics wire into the celiac plexus deep
Visceral afferents haul the pain through fibers half asleep
Epigastric burning — that's your referred ulcer ache
Left shoulder speaks in phrenic tongue when diaphragm's awake
Down in Auerbach's and Meissner's plexus, enteric neurons hum
Cajal's interstitial cells set pace — when they're gone, stomach's numb
GIST grows from those same Cajal cells — the pacemaker turned malign
Gastroparesis walks the same anatomy, different design
[Chorus]
Vagus, vagus, two trunks at the hiatus
Anterior left, posterior right, don't you confuse 'em at the table
Criminal nerve of Grassi hides up high behind the crus
Miss that fiber, ulcer's back — recurrence coming back to you
Crow's foot, celiac, Latarjet — draw the map before you sever
Confirm your cut, sweep the hiatus, parietal cell vagotomy forever
5. Module 5 — Histology and Physiology
[Verse 1]
Parietal cells line the fundic glands, pumping acid through the H-K ATPase hands
Intrinsic factor binds to B12 in the gut, lose those cells and the pathway gets cut
Chief cells drop pepsinogen into the lumen dark
Mucous neck cells coat the surface — protection is their mark
G cells live in the antrum, gastrin is their call
D cells hush with somatostatin, braking one and all
[Chorus]
Желудок — живой оркестр, каждая клетка знает свой текст
Acid, ghrelin, gastrin, histamine in phase
Cephalic, gastric, intestinal — three-stage blaze
ECL drops histamine, acetylcholine turns the key
Желудок помнит всё — remember the physiology
[Verse 2]
Three signals hit the parietal cell and open up the pump
Acetylcholine, gastrin, histamine — a triple-pathway jump
PPIs block the ATPase, H2 blockers hit the receptor wall
Prostaglandins guard the mucus, NSAIDs make the barrier fall
Bicarbonate sits beneath the mucus like a second skin
Ischemia strips the defense away and bile leaks in
Slow waves pace the antrum at three cycles every minute
Trituration grinds the solids — pylorus controls what's in it
[Chorus]
Желудок — живой оркестр, каждая клетка знает свой текст
Acid, ghrelin, gastrin, histamine in phase
Cephalic, gastric, intestinal — three-stage blaze
ECL drops histamine, acetylcholine turns the key
Желудок помнит всё — remember the physiology
[Bridge]
Now map the resection to the deficit — this is where the exam lives
Total gastrectomy takes parietal cells, B12 deficiency gives
Iron falls within months, B12 takes years to deplete
Calcium follows in the duodenum — absorption incomplete
Sleeve removes the fundus, P-D1 ghrelin drops away
Hunger signals fade — that's the metabolic trade
Roux-en-Y bypasses the antrum, gastrin climbs the scale
Incretins surge from foregut exclusion — GLP-1 tells the tale
Antral loss alone spikes gastrin, marginal ulcer threat
Migrating motor complex clears between meals — don't forget
[Verse 3]
Receptive relaxation — vagal stretch to hold the meal
Accommodation softens fundal tone so pressure stays genteel
Liquids empty faster, exponential off the curve
Solids need the antral grind before the pylorus will serve
Ghrelin from the fundus — appetite's own telegraph
Sleeve it out, the hunger signal drops by nearly half
B12 needs intrinsic factor, iron needs acid to reduce
Ferric becomes ferrous — lose the acid, lose the juice
[Chorus]
Желудок — живой оркестр, каждая клетка знает свой текст
Acid, ghrelin, gastrin, histamine in phase
Cephalic, gastric, intestinal — three-stage blaze
ECL drops histamine, acetylcholine turns the key
Желудок помнит всё — remember the physiology
[Outro]
Каждая клетка — своя роль, каждый разрез — свой счёт
Every cell has a function, every cut has a cost
Map the location to the loss — that's the clinical art
Parietal, chief, G cell, D cell — знай наизусть
6. Module 6 — Anatomy of Adjacent and At-Risk Organs
[Verse 1]
The hiatus opens like a wound in the diaphragm's floor,
Right crus, left crus, decussating fibers at the core,
Phrenoesophageal ligament holds the cardia in place,
But breach that pleural reflection — you've entered the wrong space,
The thoracic duct runs close, the vagi drape before and aft,
The left inferior phrenic bleeds quiet when you're blind and fast,
Anterior vagus, posterior vagus — count them, know them both,
One cut without intention is a surgeon's broken oath
[Chorus]
Не ріж без знання — do not cut without the map,
The aorta and the cava ask for more than casual hands,
Corte com cuidado, cada plano tem seu nome,
Five iatrogenic sins — we carry every one of them home,
Не ріж без знання — know the borders, know the cost
[Verse 2]
Kocher your duodenum, mobilize the first to third,
D-one to the GDA — the common bile duct is close, preferred
To injury than you'd wish — and at D-three the SMA sweeps across,
Ampulla of Vater, minor papilla — biliary loss
Is the second sin: the duct transected at the base,
The retroperitoneal fixation gives you just enough space,
Pancreatic head and uncinate lurk beneath the posterior wall,
A penetrating ulcer doesn't ask before it fuses all
[Chorus]
Não corte sem saber — do not cut without the map,
The aorta and the cava ask for more than casual hands,
Corte com cuidado, cada plano tem seu nome,
Five iatrogenic sins — we carry every one of them home,
Не ріж без знання — know the borders, know the cost
[Bridge]
The spleen — hilar tethering through the short gastrics runs taut,
Avulse the capsule rushing — that is sin number three, well-taught,
The middle colic vessels hide inside the mesocolon fold,
Gastrocolic dissection burns them silent, swift, and cold,
The liver's left lateral section drapes across the fundus floor,
Retract too hard and segments two and three will hemorrhage more,
Fascial planes of Toldt, mesogastric embryology —
The plane between mesogastrium and retroperitoneum is your theology
Here is the lexicon of wounds the careless hand will earn:
Esophageal perforation at the hiatus — hiatal burn,
Splenic avulsion at the greater curve — sin four, it bleeds,
Left adrenal sheared from retroperitoneum — sin five concedes,
Celiac axis, portal structures — sanguinolent, a word for blood-red,
Soaked in origin — the anatomy around what should not have bled
[Chorus]
Не ріж без знання — do not cut without the map,
The aorta and the cava ask for more than casual hands,
Corte com cuidado, cada plano tem seu nome,
Five iatrogenic sins — we carry every one of them home,
Не ріж без знання — know the borders, know the cost
7. Module 7 — Imaging, Endoscopic, and Laparoscopic Anatomy
[Verse 1]
Arterial phase blooming on the screen,
celiac axis branching like a winter tree,
hepatic left, splenic arching wide,
we map the variants before we go inside.
Water fills the stomach, gas distends the folds,
five bright layers on the ultrasound scroll —
mucosa, muscularis, the echo gaps between,
EUS is reading every wall we've never seen.
[Chorus]
T through N through M, correlate the cut,
lesser sac behind, mesenteric planes in front,
arterial phase for vessels, portal phase for wall,
PET goes dark on signet ring — it won't show all.
Read the scan like a surgeon reads the field,
every layer tells you what the knife might yield,
CT, EUS, and PET, triangulate the stage —
then you write the operation on a different page.
[Verse 2]
The Z-line marks the junction, squamous meeting red,
diaphragmatic pinch sits just a centimeter ahead.
Retroflex the scope to see the cardia wrap,
Hill grade one through four — is the flap intact?
Prague classification codes the Barrett's tongue,
C for circumferential, M for how far it's run.
The incisura angles at the lesser curve,
the pylorus guards the exit — every landmark serves.
[Chorus]
T through N through M, correlate the cut,
lesser sac behind, mesenteric planes in front,
arterial phase for vessels, portal phase for wall,
PET goes dark on signet ring — it won't show all.
Read the scan like a surgeon reads the field,
every layer tells you what the knife might yield,
CT, EUS, and PET, triangulate the stage —
then you write the operation on a different page.
[Bridge]
Fluoroscopy spills the volvulus twist,
organoaxial rotation — nothing missed,
upper GI series traces every leak,
the Roux limb pathway for the post-bariatric seek.
Laparoscopic ports reframe the hiatus view,
thirty-degree lens tilts the angle anew,
staging laparoscopy, the peritoneal wash —
cytology positive means the margins are lost.
T1 and T2 blur on contrast CT scan,
small peritoneal seeds escape the imaging plan —
that's why the scope descends before the blade,
to catch what density alone could never grade.
[Verse 3]
GIST sits beneath the mucosa, smooth and round,
EUS layers four and five is where it's found,
hypoechoic mass within the muscularis —
endoscopic biopsy won't reach what's hiding there.
Subepithelial lesions need the layered eye,
lipoma, carcinoid, varices — don't misidentify.
Compression from outside reads like a submucosal mound,
EUS resolves the question without making a sound.
[Chorus]
T through N through M, correlate the cut,
lesser sac behind, mesenteric planes in front,
arterial phase for vessels, portal phase for wall,
PET goes dark on signet ring — it won't show all.
Read the scan like a surgeon reads the field,
every layer tells you what the knife might yield,
CT, EUS, and PET, triangulate the stage —
then you write the operation on a different page.
8. Module 8 — Benign and Inflammatory Pathology
[Verse 1]
Helicobacter's coiled beneath the mucous layer, patient,
Urease splitting urea, alkaline and ancient,
Test the breath for carbon, check the stool for antigen,
Biopsy confirms it, serology is older kin,
Triple therapy fading where resistance has grown thick,
Bismuth quadruple regimen when the first line doesn't stick,
NSAIDs strip the prostaglandins, aspirin does the same,
Stress ulcers bloom in ICU — prophylaxis is the game
[Chorus]
Johnson One through Five, learn the acid-secretion rhyme,
Type One sits at lesser curve, low acid every time,
Forrest grades the bleeding — one-A spurting, two-B slow,
Epinephrine, clips, and heat — three-point-ligate the GDA below,
Always biopsy the gastric ulcer, never let it go,
Malignancy is hiding where the margins seem to show
[Verse 2]
Graham patch the perforation, omentum soft as gauze,
Oversew the duodenum, mind the pancreatic branch because
The transverse vessel lurks there, ligate it and you'll weep,
Vagotomy and drainage when the acid is too deep,
Antrectomy now narrowed — reserved for those who fail,
Zollinger-Ellison secreting gastrin past the pale,
Gastrinoma triangle — portal, cystic, neck of pancreas drawn,
Secretin paradox: gastrin rises, not withdrawn
[Chorus]
Johnson One through Five, learn the acid-secretion rhyme,
Type One sits at lesser curve, low acid every time,
Forrest grades the bleeding — one-A spurting, two-B slow,
Epinephrine, clips, and heat — three-point-ligate the GDA below,
Always biopsy the gastric ulcer, never let it go,
Malignancy is hiding where the margins seem to show
[Bridge]
Correa's cascade — normal mucosa, atrophy, then metaplastic cells,
Ménétrier's protein-losing, giant rugae, gastrin swells,
Hiatal hernia Types One through Four — sliding, rolling, mixed, intrathoracic gone,
Borchardt's triad: pain, retching, tube won't pass — organoaxial volvulus is on,
Dieulafoy's a submucosal artery, massive bleed, no ulcer found,
Watermelon stomach, GAVE, antral vessels fanned around,
Mallory-Weiss tears the cardia — but if it ruptures all the way,
That's Boerhaave, mediastinum drowning, don't delay
[Verse 3]
Gastroparesis slows the emptying, the stomach heavy, still,
Diabetic nerves and post-vagotomy — G-POEM fits the bill,
Pyloromyotomy opens what the scarring has constricted,
Gastric stimulator placed when motility's afflicted,
Portal hypertensive gastropathy — mosaic tiles of red,
Splenic vein thrombosis feeds the gastric varices instead,
Sarin classifies them — IGV-One means splenectomy is cure,
Four types of hiatal — giant hernias need crural closure sure
[Chorus]
Johnson One through Five, learn the acid-secretion rhyme,
Type One sits at lesser curve, low acid every time,
Forrest grades the bleeding — one-A spurting, two-B slow,
Epinephrine, clips, and heat — three-point-ligate the GDA below,
Always biopsy the gastric ulcer, never let it go,
Malignancy is hiding where the margins seem to show
9. Module 9 — Neoplastic Pathology
[Verse 1]
H. pylori carving grooves into the antral wall
EBV hijacks the nucleus, diffuse type hits us all
Diet high in salt and nitrates, prior Billroth scarred the fold
CDH1 mutation — prophylactic gastrectomy, age told
Laurén said intestinal grows in glands, diffuse floats free
Signet rings don't form a mass, they infiltrate like debris
Linitis plastica, leather bottle, Borrmann Type Four's the worst
TCGA cut four subtypes — EBV, MSI first
[Chorus]
TNM staging, D-zwei Lymphadenektomie
Schneid die Ränder sauber — frozen section, can't be free
Resezione en bloc, margine netto, non cedere
HER2, PD-L1, MSI — la chiave per guarire
Stage it, cut it, sequence right — perioperative decree
FLOT vier Zyklen vor, vier nach — das ist die Therapie
[Verse 2]
Siewert Type One goes thoracic, CROSS trial leads the call
Type Two and Three go abdominal, gastric margins cover all
MAGIC showed periop chemo works, ECF around the knife
FLOT4 proved triplet docetaxel cuts deeper into life
INT-0116 — adjuvant chemorad when surgery stands alone
CLASSIC and ARTIST closed the Asian loop, capecitabine-owned
Claudin 18.2, a tight junction turned target, zolbetuximab's door
Checkpoint blockade for MSI-high — pembrolizumab at the fore
[Chorus]
TNM staging, D-zwei Lymphadenektomie
Schneid die Ränder sauber — frozen section, can't be free
Resezione en bloc, margine netto, non cedere
HER2, PD-L1, MSI — la chiave per guarire
Stage it, cut it, sequence right — perioperative decree
FLOT vier Zyklen vor, vier nach — das ist die Therapie
[Verse 3]
D2 dissection spares the spleen unless invasion's there
Dutch trial showed survival gain without the morbid snare
Subtotal beats total when the distal margin's clear
Laparoscopy first — cytology decides the frontier
Positive washings shift the stage, M1 without a mass
HIPEC and PIPAC — the evidence is thin as glass
Palliative resection only when obstruction bleeds or blocks
Early gastric, ESD criteria — submucosal depth unlocks
[Bridge]
GIST biologia — KIT o PDGFRA
Mitosi alte, grande dimensione — rischio che cresce già
Wedge resection, negative margin, no node dissection needed
Kapsel intakt — lass sie ganz — zerreißen ist verboten
Imatinib neoadjuvant shrinks the unresectable beast
Adjuvant three years post resection, high-risk recurrence ceased
D816V PDGFRA resists — switch to avapritinib's arm
Exon 9 KIT needs higher dosing — sequence before you harm
[Chorus]
TNM staging, D-zwei Lymphadenektomie
Schneid die Ränder sauber — frozen section, can't be free
Resezione en bloc, margine netto, non cedere
HER2, PD-L1, MSI — la chiave per guarire
Stage it, cut it, sequence right — perioperative decree
FLOT vier Zyklen vor, vier nach — das ist die Therapie
[Outro]
Lynch syndrome watches mismatch, FAP distorts the fundic gland
Li-Fraumeni, Peutz-Jeghers — hereditary demand
Surveil the remnant, biopsy deep, no margin left behind
Gastric cancer staged and sequenced — sharpen body, sharpen mind
10. Module 10 — Operative Techniques, Reconstruction, and Post-Gastrectomy States
[Verse 1]
Scalpel down the greater curve, preserve that gastroepiploic arc,
Right side feeds the conduit up — you sever that, you're cutting in the dark.
Distal gastrectomy, sweep the antrum clean,
Subtotal for the corpus, total when it's mean.
Proximal resection needs a double-tract or esophagogastrostomy,
Wedge it out for GISTs, pyloromyotomy splits the ring for free.
[Chorus]
Billroth One, Two, Roux-en-Y — know your letters, know your loops,
Antecolic, retrocolic, close the Petersen's space to stop the troops.
Stapled or hand-sewn, check your tension and perfusion with the ICG glow,
Choose your reconstruction, execute it clean, manage every undertow.
[Verse 2]
Heineke-Mikulicz flips the cut transverse, Finney makes a wider gate,
Jaboulay sidesteps the pylorus whole — vagotomy seals the fate.
Braun enteroenterostomy defunctioned the afferent snare,
Roux stasis, alkaline reflux — bile scorching tissue bare.
Gastrojejunostomy for bypass when obstruction blocks the road,
Duodenal stump blowout blows the whole damn episode.
[Chorus]
Billroth One, Two, Roux-en-Y — know your letters, know your loops,
Antecolic, retrocolic, close the Petersen's space to stop the troops.
Stapled or hand-sewn, check your tension and perfusion with the ICG glow,
Choose your reconstruction, execute it clean, manage every undertow.
[Verse 3]
Early dumping floods the bowel fast, osmotic surge, the vasovagal swing,
Late dumping's hypoglycemia — reactive insulin sting.
Esophagojejunal leak, that anastomosis wept,
Pancreatic fistula after D2 lymphadenectomy — kept
Drains in long, fed distal through the jejunostomy line,
Chyle leak runs milky white — a rare efflorescence, lymph and fat combined.
[Bridge]
Bariatric anatomy on the trauma board tonight —
Sleeve, gastric bypass, one-anastomosis, internal hernia in the right
Mesocolic defect, Roux limb twisted, bowel caught inside the gap,
CT shows a swirling mesentery — don't miss that diagnostic trap.
Blind loop overgrowth, B12 depleted, iron tanked, bone crumbling slow,
Metabolic sequelae compound for years, remnant cancer seeds below.
[Chorus]
Billroth One, Two, Roux-en-Y — know your letters, know your loops,
Antecolic, retrocolic, close the Petersen's space to stop the troops.
Stapled or hand-sewn, check your tension and perfusion with the ICG glow,
Choose your reconstruction, execute it clean, manage every undertow.
[Outro]
Supplement the B12, fold in folate, calcium, vitamin D,
Surveil that remnant mucosa — adenocarcinoma lurks in history.
Marginal ulcer bleeds at midnight, damage control when trauma tears the wall,
Efflorescence — rare and vivid, lymph blooming where the chyle will fall.
Know the loops, close the gaps, feed distal, watch the stump —
Every anastomosis earns its patency or gets the pump.
11. Module 11 — Perioperative Care, Guidelines, and Evidence
[Verse 1]
Before the blade, we build the body up
Prehabilitation, fill the nutritional cup
Arginine and omega threes, immunonutrition primed
ERAS protocols mapped out, nothing left behind
Carbohydrate loading, shorten that fasted state
Two hours for clear fluids, never make them wait
Frailty scores calculated, gait speed measured slow
The fragile ones need more runway before they go
[Chorus]
NCCN, ESMO, Japanese guidelines read in full
ACG for bleeding ulcers, SAGES makes the pull
WSES for perforation, ASMBS bariatric code
Know the evidence, defend your deviations on that road
Node count adequacy, margins clean and clear
Leak rates, failure to rescue — the metrics that we fear
Read the landmark trial, know the update from last year
Perioperative precision — that's the science we hold dear
[Verse 2]
VTE prophylaxis, don't you stop at discharge
Cancer patients need extended coverage, think large
Twenty-eight days minimum, low molecular weight
Clot formation in the silent hours won't negotiate
Risk stratification, Caprini score in hand
Epidural or systemic, analgesia well-planned
Nasogastric tubes pulled early, mobilize day one
Multimodal analgesia till the opioid burden's done
[Chorus]
NCCN, ESMO, Japanese guidelines read in full
ACG for bleeding ulcers, SAGES makes the pull
WSES for perforation, ASMBS bariatric code
Know the evidence, defend your deviations on that road
Node count adequacy, margins clean and clear
Leak rates, failure to rescue — the metrics that we fear
Read the landmark trial, know the update from last year
Perioperative precision — that's the science we hold dear
[Bridge]
Tumor board convenes, the voices multiply
Oncology and surgery read the CT side by side
Palliative care enters early, not at the final breath
Goals of care articulated long before the threat
What does this patient value, what does function mean
The advanced disease conversation — hardest one to scene
Document the wishes, code status on the chart
Multidisciplinary presence is the discipline's art
[Verse 3]
Journal club, you're presenting, pick your landmark well
FLOT versus ECF — let the survival curves tell
Hazard ratios matter, confidence intervals too
One guideline update current, last two years reviewed
Fifteen lymph nodes minimum, D2 dissection counts
R-zero resection — that's the margin that amounts
Present it with precision, someone will push back hard
Defend your interpretation, every deviation scarred
[Outro]
So read the guidelines fully, not the abstract alone
ESMO, NCCN — make the evidence your own
Quality metrics anchor every operative choice
Perioperative care demands a rigorous, steady voice
12. Module 12 — Skills, Simulation, and Milestone Progression
[Verse 1]
Two sessions in the cadaver lab, celiac axis mapped in cold
Lesser sac peeled back like pages, every lymph node station told
The hiatus measured, traced and memorized — T10, the vagus threads
This isn't textbook passive reading, this is knowledge built from hands
Novice level: name the variants, assist without a fumble
Peptic ulcer, medical — H2 blocker, triple, humble
Learn the staple before the suture, learn the port before the blade
Every logbook entry dated, every level of grade
[Chorus]
Clips and injection, thermal coagulation
Hemostatic powder pressed to the station
Graham patch, then gastrostomy, hiatal repair supervised
Distal then total, D2 lymphadenectomy — graded and authorized
Novice, intermediate, advanced, independent — four rungs, don't rush the climb
Watch the reference video, match your hands to the line
[Verse 2]
Upper endoscopy — the scope descends through the cardia and the fold
You're hunting for the bleeder now, the stigmata sharp and cold
Clip deployment, over-the-scope, injection of epinephrine true
Thermal probe at tangent angle — hemostasis through and through
Laparoscopic suturing drills, the anastomosis model waits
Intracorporeal hand-tied knots, tension checked before you close the gates
Intermediate expects you bringing Graham patch without a net
Gastrojejunostomy flowing — but still supervised, not done yet
[Chorus]
Clips and injection, thermal coagulation
Hemostatic powder pressed to the station
Graham patch, then gastrostomy, hiatal repair supervised
Distal then total, D2 lymphadenectomy — graded and authorized
Novice, intermediate, advanced, independent — four rungs, don't rush the climb
Watch the reference video, match your hands to the line
[Bridge]
Advanced: the distal gastrectomy, reconstruction mapped and staged
Bleeding ulcer — operative — Billroth or a Roux engaged
Staging CT read alone now, no co-sign on the call
Independent — total gastrectomy, D2, you run the hall
Leak surveillance, dumping syndrome, alkaline reflux — own the syndrome cascade
Lead the MDT, pathology to palliation — every plan you've laid
[Verse 3]
Pull the video of your own hands, set it next to the expert cut
Frame by frame the tension differs, there's the moment that you rushed the gut
Graded responsibility climbing — not a rank but an anatomy of trust
Operative logbook filling — every entry earned, not given, just
Named the celiac branches, simulated, sutured, scoped, and read
Now the milestones stack like vertebrae — a scaffold, not a ceiling overhead
[Chorus]
Clips and injection, thermal coagulation
Hemostatic powder pressed to the station
Graham patch, then gastrostomy, hiatal repair supervised
Distal then total, D2 lymphadenectomy — graded and authorized
Novice, intermediate, advanced, independent — four rungs, don't rush the climb
Watch the reference video, match your hands to the line
13. Core References
[Verse 1]
Sabiston lays the stomach open, page by careful page,
Schwartz draws the blood supply in margins, chapter, and in stage,
Maingot walks the gastric sections, hands that knew the knife,
These are the references that anchor surgical life,
From the cardia to the pylorus, every layer named,
Zollinger shows the operative field, nothing left unclaimed
[Chorus]
Sabiston, Schwartz, and Maingot — three pillars in the wall,
Fischer shows the mastery, Skandalakis the hall,
Japanese guidelines classify, NCCN defines the call,
AJCC stages every tumor, ESMO covers all,
Read them like a reckoning, slow and methodical,
These are the references, not peripheral — they're the protocol
[Verse 2]
Fischer's Mastery holds the technique like a steady hand,
Zollinger's Atlas draws the planes most surgeons understand,
But Skandalakis goes deeper, embryology and bone,
The fascial planes and variants that textbooks leave alone,
Where the foregut folded over, where the vessels trace their root,
Skandalakis maps the history beneath the surgeon's route
[Chorus]
Sabiston, Schwartz, and Maingot — three pillars in the wall,
Fischer shows the mastery, Skandalakis the hall,
Japanese guidelines classify, NCCN defines the call,
AJCC stages every tumor, ESMO covers all,
Read them like a reckoning, slow and methodical,
These are the references, not peripheral — they're the protocol
[Verse 3]
The Japanese Association drew the cancer classifications tight,
Numbered every lymph node station, proximal left to right,
Their treatment guidelines carry decades of resection data deep,
A discipline of margin and of systematic sweep,
NCCN and ESMO answer from the Western side,
Two traditions in a conversation, neither one denied
[Bridge]
And the AJCC staging manual holds the final word on spread,
T through N through M — the alphabet of what lies ahead,
But these are living documents, they shift with every trial,
Verify against the current version, check the latest file,
No framework is a substitute for standing in that room,
Supervised, awake, and present — let the knowledge bloom
[Verse 4]
So build your understanding on these references like stone,
Not to recite the pages but to make the thinking your own,
Every operative question has a chapter at its root,
Every staging conversation has a manual in its suit,
The stomach is a complex organ, history runs through it,
These books are the cartographers — you learn to navigate it
[Chorus]
Sabiston, Schwartz, and Maingot — three pillars in the wall,
Fischer shows the mastery, Skandalakis the hall,
Japanese guidelines classify, NCCN defines the call,
AJCC stages every tumor, ESMO covers all,
Read them like a reckoning, slow and methodical,
These are the references, not peripheral — they're the protocol
