Background
During cytoreductive surgery and hyperthermic intraperitoneal chemotherapy (CRS/HIPEC), surgeons are reluctant to perform unprotected pelvic anastomosis despite lack of supporting data. We analyzed pelvic anastomosis outcomes and factors that influence ostomy creation in CRS/HIPEC patients.
Methods
A single-center, descriptive study of patients with rectal resection during CRS/HIPEC was conducted using a prospective database. Surgical variables were reviewed. Multinomial logistic regression of outcomes (end or protective ostomy) was performed with pre- and intraoperative factors as predictors.
Results
Overall, 274 of 789 CRS/HIPEC patients underwent rectal resection, including 243 (89%) with pelvic anastomosis [232 (85%) without ostomy, 11 (4%) with protective ileostomy] and 31 (11%) with no anastomosis [16 (6%) with end colostomy, 15 (5%) with end ileostomy]. The median age was 57 and 29% (79) were male. Of 243 pelvic anastomosis patients, 3 (1.2%) had rectal anastomotic leaks, including 1 with a protective ileostomy. Other anastomotic leaks occurred in 3.6%. Overall, 13% had Clavien-Dindo complications ≥ IIIB and the readmission rate was 30%. Mortality at 30 days and 100 days was 0.4% and 2.2%, respectively. Male gender and primary rectal cancer were associated with protective ileostomy [odds ratio (OR) = 7.01, 95% CI: 1.6–31.5, p = 0.011, and OR = 16.4, 95% CI: 3–88.4, p = 0.001, respectively). Male gender and prior pelvic surgery were associated with end colostomy (OR = 13.9, 95% CI: 3.7–53, p < 0.0001, and OR = 17.2, 95% CI: 3.8–78.6, p < 0.0001).
Conclusions
Pelvic bowel reconstruction without protective or end ostomy during CRS/HIPEC is safe. Protective ileostomy is associated with male gender and primary rectal cancer. End colostomy is associated with male gender and prior pelvic surgery.
