Preoperative criteria of incomplete resectability of peritoneal carcinomatosis from non-appendiceal colorectal carcinoma.

Objective: To analyse the causes of non resectability of peritoneal carcinomatosis (PC) of non-appendiceal colorectal carcinomas, discovered only at the time of the laparotomy.

Summary Background Data: The combination of a maximal cytoreductive surgery (resecting tumor deposits > 1 mm in diameter) with intraperitoneal chemohyperthermia results in cure a significant number of patients. Complete resection of the PC is the determining factor of this time-consuming and resource-consuming therapy.
