Operative steps for major GI surgeries
1. Abdomen is opened from the Bilateral Subcostal incision. (chevron)
2. Abdominal cavity is explored for metastasis especially liver, base of mesentary, mesocolon, pelvis.
3. Kocher's maneuver performed and duodenum along with the head of pancreas mobilized to the midline. This step exposes the IVC.
4. Cattle baarsch maneuver done and hepatic flexure of colon is brought down.
5. Superior Mesenteric Vein is seen passing from the mesentary to its course to join the portal vein.
6. At this step attempt may be made to try and create the tunnel between the Superior mesenteric vein and pancreas but if it is problematic it may be attempted at the later stage.
It is at this crucial time the resectability for Pancreaticoduodenectomy is decided.
7.Dissection is started at the free border of lesser sac and Common bile duct, Right hepatic artery and portal vein are identified. At this step special care is taken to identify and safeguard accessory or replaced Right hepatic artery. This artery is easily found posterolateral to the portal vein.
8. Gall bladder is dissected from the liver bed and followed onto the cystic duct, Common bile duct is divided at the junction with the cystic duct.
9. The Right hepatic artery is traced back and just above the duodenum Gastro duodenal artery is tied off.
10. The hepatoduodenal ligament is diisected easily as its avascular and next after clearing the lesser curve of stomach and greater curve, stomach is usually transected with a linear cutter.
11. The portal vein is now seen clearly and the tunnel between it and pancreas is fashioned. Image
12. The pancreas is now cut and separated from the portal vein. There are many ways to do it and recently we have been doing it with a vascular stapler.
