Abstract
Background
Gastrointestinal complications, predominantly anastomotic leak (AL), are the most frequent source of severe morbidity after cytoreductive surgery (CRS).
Objective
The aim of this study was to present the technical standards for colorectal anastomoses developed and systematically applied to all patients undergoing CRS in a high-volume tertiary center, and the associated AL rates.
Methods
This was a descriptive study reporting the technical characteristics of a standardized protocol for three types of colorectal anastomoses (colorectal, ileorectal, and ileocolic) in CRS with heated intraperitoneal chemotherapy (HIPEC), and a retrospective analysis of prospectively collected data on anastomotic outcomes. All patients (1172) undergoing CRS with HIPEC from September 2006 to September 2020 were included. The anastomotic complications were classified according to the International Study Group of Rectal Cancer Surgery (ISGRCS) classification.
Results
Overall, 1172 patients underwent 1300 procedures and 1359 gastrointestinal anastomoses. An ileocolic anastomosis was performed in 408 patients, colorectal anastomosis in 469 patients, and ileorectal anastomosis in 16 patients, none with diverting ileostomy; 345 other gastrointestinal reconstructions and 82 urinary reconstructions were performed in these patients. The AL rate was 1% (4/408) for the ileocolic anastomosis, 0.85% (4/469) for the colorectal anastomosis, and 0% (0/16) for the ileorectal anastomosis. One patient died postoperatively due to AL.
Conclusions
Systematic application of standardized techniques adapted to ensure optimal tissue healing (stapled anastomoses avoiding overlap, accurate staple deployment, and hand-sewn reinforcement) are associated with a very high level of anastomotic safety in a large cohort of patients undergoing CRS and HIPEC.
