A Near-Zero Anastomotic Leak Rate in Cytoreductive Surgery with Heated Intraperitoneal Chemotherapy is Achievable.

Abstract

Gastrointestinal complications are the main source of severe morbidity after cytoreductive surgery (CRS) and heated intraperitoneal chemotherapy (HIPEC), mainly in the form of anastomotic leak. Reducing the rate of anastomotic leaks is of paramount importance and should be approached both through risk factor understanding and reduction, as well as optimization of surgical team performance. We performed a study that describes the details of a technical protocol for the creation of anastomoses after colorectal resections in CRS and HIPEC and the anastomotic outcomes associated with its systematic application in a high-volume peritoneal surface malignancy center. An extremely low, near-zero anastomotic leak rate (0.85% in colorectal anastomoses, 1% in ileo-colic anastomoses, and 0% in ileo-rectal anastomoses) was observed among 1172 patients. Extremely low, near-zero rates of anastomotic leak after colorectal resections in CRS and HIPEC could be achievable in high-volume peritoneal malignancy centers. The described techniques could be adopted and validated in other high-volume peritoneal malignancy centers.
