Partial gastrectomy with Roux-en-Y gastrojejunostomy - general and visceral surgery

Open the abdomen through an epigastric midline incision, with left periumbilical extension caudad After inserting the abdominal retractor system, explore the abdominal cavity and assess the location and extent of the primary tumor as well as any lymph node involvement and organ metastases.

Pull up the greater omentum and apply measured traction against the transverse colon. Dissect the greater omentum close to the upper aspect of the transverse colon and open the lesser sac.
After freeing the hepatic flexure and descending duodenum and carefully dividing the greater omentum off its adhesions with the mesocolon on the right, divide the gastroepiploic vessels entering here. Divide the right gastroepiploic vein before its union with the superior mesenteric vein, and the right gastroepiploic artery where it leaves the gastroduodenal artery.

Lymphadenectomy (LAD) starts at the hepatic hilum and continues along the hepatoduodenal ligament and common hepatic artery to the celiac trunk.

After the cholecystectomy, not demonstrated here, incise the lesser omentum with bipolar scissors close to the liver. Start the incision on the left side of the hepatoduodenal ligament and continue to the level of the cardia. With forceps lift the connective tissue together with all its lymph nodes (LN) anterior to the common hepatic artery at the left aspect of the hepatoduodenal ligament and expose the artery. Gradually dissect the LN tissue bundle (station 12) off the portal vein and common bile duct. After inserting the index finger into the omental foramen, palpate the common hepatic artery, hepatic artery proper, portal vein, and any possibly suspect lymph nodes with thumb and index finger. Now take down LN station 13 between the head of the pancreas and the portal vein.
