To determine (laparoscopic) resectability of the tumor, opening of the lesser sac is achieved by detaching the greater omentum from the transverse colon by sharp dissection. In case of a benign indication, opening of the lesser sac can be performed more easily by creating a window in the greater omentum, for instance by using Ultracision. Involvement of the pancreas in malignant tumors requires conversion to open resection in most cases. In case of malignancy, once resectability has been established, the lesser sac is opened until the gastrocolic ligament is completely dissected from the hepatic to the splenic flexure.
