[Verse 1]
Cardia at the top where the oesophagus lands,
Fundus balloons above, then the body expands,
Antrum grinds it down, pylorus controls the gate,
Lesser curve runs short, greater curve swings wide — get the shape straight,
Incisura angularis — that angular notch on the lesser side,
Where the body meets the antrum, carve that landmark in your mind,
Angle of His at the junction, phrenoesophageal ligament holds the seal,
Crura clamp around the hiatus, that's the antireflux deal,
Three muscle layers — oblique inside, then circular, then longitudinal last,
Mucosa holds the parietal cells pumping acid fast,
Chief cells drop pepsinogen, G cells fire gastrin loud,
ECL cells release histamine, D cells somatostatin-proud
[Chorus]
O estômago tem regiões — cardia, fundo, corpo, antro, piloro,
Artérias do celíaco — esquerda, direita, epiploicas — é um tesouro,
Left gastric, right gastric, epiploics form the ring,
Curvas, ligamentos, vagas — the stomach does everything
[Verse 2]
Celiac trunk divides — left gastric climbs the lesser curve,
Right gastric anastomoses below, completing that reserve,
Left gastroepiploic from the splenic, right from gastroduodenal,
Short gastrics from the splenic too — five sources, keep it mental,
Replaced right hepatic off the SMA — variant you can't ignore,
Accessory left hepatic in the gastrohepatic ligament — check before you score,
Venous drainage mirrors it — portal system receives the flow,
Left gastric vein — the coronary — connects where varices grow,
Portal hypertension backs it up, submucosal veins dilate and bleed,
TIPS or shunt or banding — know the reason, know the need
[Chorus]
O estômago tem regiões — cardia, fundo, corpo, antro, piloro,
Artérias do celíaco — esquerda, direita, epiploicas — é um tesouro,
Left gastric, right gastric, epiploics form the ring,
Curvas, ligamentos, vagas — the stomach does everything
[Bridge]
Gastrohepatic ligament — lesser omentum, lesser sac behind,
Foramen of Winslow — hepatoduodenal window, Pringle's where you clamp the line,
Gastrocolic hangs below, gastrosplenic runs left, gastrophrenic pins the dome,
Lymph nodes numbered one to sixteen — Japanese system, that's the home,
D1 perigastric only, D1-plus adds seven and eight,
D2 dissection — celiac axis nodes — that's the curative rate,
Nerve of Latarjet — anterior and posterior branches glide,
Criminal nerve of Grassi — first posterior branch, incomplete vagotomy's guide,
Anterior trunk is left vagus, posterior trunk comes from the right,
Hepatic branch swings to the liver, celiac branch drops out of sight
[Chorus]
O estômago tem regiões — cardia, fundo, corpo, antro, piloro,
Artérias do celíaco — esquerda, direita, epiploicas — é um tesouro,
Left gastric, right gastric, epiploics form the ring,
Curvas, ligamentos, vagas — the stomach does everything
