[Verse 1]
Four parts carving through the abdomen's core
C-shaped cradle, retroperitoneal, pressed to the floor
First part rises from the pylorus, free to move
Second part — descending, where the papilla proves
The ampulla of Vater opens here, bile and enzyme meet
Sphincter of Oddi gates the flow — precise, discrete
Third part crosses horizontal, SMA bears down above
SMV to the right, aorta tucked below — a surgical glove
Fourth part climbs to Treitz, the ligament suspends
Marks the duodenum's finish where the jejunum begins
[Chorus]
El duodeno, cuatro partes en C
Retroperitoneal — зафіксований, вільний не
Ampulla of Vater, sphincter holds the gate
Четыре части — memorise your fate
El duodeno, cuatro partes en C
CBD and pancreas — locked in anatomy
[Verse 2]
Blood supply runs dual — an arcade built for war
Gastroduodenal artery branches from the hepatic door
Superior pancreaticoduodenal splits anterior and post
Then inferior rises from the SMA — they toast
Where superior meets inferior — watershed terrain
Compromise one vessel and the other holds the strain
Divided territory, shared perfusion, elegant design
Surgeons map this arcade before they cut the line
[Chorus]
El duodeno, cuatro partes en C
Retroperitoneal — зафіксований, вільний не
Ampulla of Vater, sphincter holds the gate
Четыре части — memorise your fate
El duodeno, cuatro partes en C
CBD and pancreas — locked in anatomy
[Verse 3]
Minor papilla sits above, accessory duct drains there
Santorini's channel — backup when the main can't share
The CBD descends posterior through the pancreatic head
Groove and groove until the ampulla — common channel fed
The sphincter of Oddi — smooth muscle, three-zone wrap
Regulates pressure, blocks reflux, no bacterial gap
Dysfunction here means pancreatitis knocking loud
Biliary dyskinesia hiding in the crowd
[Bridge]
Кохер говорить — відкрий за очеревиною
Kocher maneuver, mobilise the duodenum
Incise the lateral peritoneum, sweep it medial slow
Expose the IVC, the aorta sitting below
Now you palpate the CBD behind the head
Assess the vascular axis — nothing left unsaid
El cirujano conoce cada plano, cada capa
Anatomy remembered saves the patient on the tabla
[Chorus]
El duodeno, cuatro partes en C
Retroperitoneal — зафіксований, вільний не
Ampulla of Vater, sphincter holds the gate
Четыре части — memorise your fate
El duodeno, cuatro partes en C
CBD and pancreas — locked in anatomy
[Outro]
Ligament of Treitz — your landmark, carve it deep
Four parts, two arcades, one sphincter — yours to keep
Retroperitoneal, relational, clinically precise
El duodeno — study it once, remember it twice
