[Verse 1]
Grab the scope, we're going in through the upper GI tract
Oesophagus, stomach, duodenum — catalogue each fact
Indications: dysphagia, bleeding, Barrett's on the radar
Biopsy protocol, Sydney System, map the antrum, body, cardia
Five samples minimum, orient them proper on the board
H. pylori hunting, chronic gastritis on record
Paris classification — flat, depressed, polypoid morphology
Zero-one through zero-three, read the mucosa like topology
[Chorus]
Forrest one-A, spurting vessel, intervene right now
One-B oozing, two-A visible vessel, clip it down somehow
Two-B clot adherent, two-C flat spot, three is clean base
Sydney, Paris, Forrest — every classification knows its place
Scope it, grade it, treat it, stage it — precision every case
[Verse 2]
Now colonoscopy — bowel prep first, polyethylene glycol split dose
Cecal intubation, appendix orifice, ileocecal valve, that's how you know
Adenoma detection rate, the metric clinicians track and measure
Cold snare polypectomy under ten millimetres is the treasure
EMR for sessile lesions, inject-and-lift, submucosal plane
ESD for en-bloc resection, longer procedure, higher gain
Tattoo three quadrants distal to lesion before it disappears
Surveillance intervals: low-risk three to five years, high-risk one year
[Chorus]
Forrest one-A, spurting vessel, intervene right now
One-B oozing, two-A visible vessel, clip it down somehow
Two-B clot adherent, two-C flat spot, three is clean base
Sydney, Paris, Forrest — every classification knows its place
Scope it, grade it, treat it, stage it — precision every case
[Verse 3]
Endoscopic ultrasound — layer by layer, T-staging gastric wall
T1 mucosa-submucosa, T2 muscularis, T3 breaks through all
T4 hits adjacent structures — EUS tells you before you cut
Rectal cancer staging same principle, relationship to the gut
GIST evaluation — hypoechoic, muscularis propria origin
Spindle cells, mitotic index, risk stratification discipline
Capsule endoscopy for obscure GI bleed, small bowel mapped complete
Device-assisted enteroscopy — balloon-assisted, reach the feat
[Bridge]
Flex sig for distal colon, rigid proctoscope for the anorectum
Anoscopy for haemorrhoids and fissures — lower tech but never forget them
Interventional arsenal: haemostasis with clips, adrenaline injection
Stenting for malignant obstruction, dilation for stricture correction
PEG placement — percutaneous endoscopic gastrostomy for nutrition
Endoscopic suturing, full-thickness resection — surgical precision
Every tool a different answer to a different clinical question
[Chorus]
Forrest one-A, spurting vessel, intervene right now
One-B oozing, two-A visible vessel, clip it down somehow
Two-B clot adherent, two-C flat spot, three is clean base
Sydney, Paris, Forrest — every classification knows its place
Scope it, grade it, treat it, stage it — precision every case
