Peritonectomy procedures.

Decisions regarding the treatment of cancer depend on the anatomic location of the malignancy and the biologic aggressiveness of the disease. Some patients may have isolated intraabdominal seeding of malignancy of limited extent or of low biologic grade. In the past these clinical situations have been regarded as lethal. We have used the cytoreductive approach to achieve long-term disease-free survival in some patients with peritoneal carcinomatosis, peritoneal sarcomatosis, or mesothelioma. The cytoreductive approach may require six peritonectomy procedures to resect or strip cancer from all intraabdominal surfaces. These are (1) greater omentectomy-splenectomy, (2) left upper quadrant peritonectomy, (3) right upper quadrant peritonectomy, (4) lesser omentectomy-cholecystectomy with stripping of the omental bursa, (5) pelvic peritonectomy with sleeve resection of the sigmoid colon, and (6) antrectomy. These peritonectomy procedures and preparation of the abdomen for early postoperative intraperitoneal chemotherapy are described.
