Abstract
BACKGROUND: Formation of protective stoma as part of cytoreductive surgery and hyperthermic intraperitoneal chemotherapy (CRS-HIPEC) may be an effective tool in reducing anastomotic leak incidence. Our aim was to evaluate the incidence and implications of stoma formation during CRS-HIPEC and to examine whether a creation of protective stoma reduces the postoperative morbidity.
METHODS: A cohort retrospective analysis of all CRS-HIPEC procedures performed between 2004 and 2016 was conducted. Predicting factors for stoma formation were assessed by comparing all patients who underwent stoma formation to those who did not; both groups were then restricted to cases with ≥2 bowel anastomoses and compared in terms of perioperative outcomes in order to determine whether protective stoma confers a morbidity benefit.
RESULTS: One hundred and ninety-nine CRS-HIPEC procedures were performed on 186 patients. Thirty-four patients (17%) underwent stoma formation, 24 of them as protective stoma. Formation of a stoma was correlated with higher peritoneal carcinomatosis index score (13.6 ± 8 vs. 9.5 ± 7.7, p = 0.007), larger number of organs resected (p < 0.001), greater number of anastomoses (p < 0.001), prolonged operative time (8.1 ± 2.7 vs. 6.6 ± 2.2 h, p = 0.002), and prolonged hospital stay (12 vs. 8.5 days, p = 0.001). In procedures requiring ≥2 anastomoses, formation of protective stoma reduced the anastomotic leak rate (6 vs. 37%, p = 0.025), the morbidity rate (6 vs. 41%, p = 0.017), and reoperation rate (0 vs. 28%, p = 0.03). Overall, 15 patients (44%) underwent stoma reversal, 3 of whom had a complication treated non-operatively.
CONCLUSIONS: Protective stoma should be considered in extensive CRS-HIPEC procedures requiring two or more bowel anastomoses in order to reduce the postoperative morbidity rate.
