Resection of tumor from the supragastric lesser sac with peritonectomy.
This 48 yr old lady underwent laparotomy for primary appendiceal carcinoma metastatic within the peritoneal cavity including the lesser omentum (LO) and supragastric lesser sac (Fig. 1). The left triangular ligament was divided allowing retraction of the left lobe of the liver. The stomachwasmanually pulled to stretch out the LO and facilitate resection. The left gastric, common hepatic and left hepatic arteries and the vagal nerves of Latarjet running along the lesser curve of the stomachwere avoided. Tumorwasmobilized frombetween the left liver and anterior caudate lobe and from behind the pont hepatique. Care was taken to avoid damage to a branch of the left hepatic artery running in the roof of the lesser sac. The stomach was elevated and the caudate lobe carefully retracted to expose the posterior surface of the supragastric lesser sac formed by a single layer of peritoneum. This was stripped off and then detached from the caudate lobe. Tumor was then stripped or wiped off the anterior surface of the caudate lobe. Residual visible tumor was ablated. At the end of the procedure there was no visible disease. The patientwas then treatedwith hyperthermic intraperitoneal chemotherapy with mitomycin for 90min. The postoperative course was uncomplicated apart from short-term ileus and urinary retention.
