Is it safe to perform rectal anastomosis in gynaecological debulking surgery without a diverting stoma?

AimColorectal resection is frequently performed during cytoreductive surgery for gynaecological malignancy. The aim of this study was to assess the safety of colorectal anastomosis, and especially low rectal anastomosis, in the absence of a protective stoma in patients with gynaecological cancer and peritoneal metastasis. MethodPatient data were retrospectively collected from a database for gynaecological cancer procedures carried out between January 2013 and July 2015. All patients who underwent a colorectal resection during cytoreduction were included in the study. The primary outcome was anastomotic leakage in the presence or absence of a diverting stoma. Secondary outcome parameters were complications and reoperations. ResultsIn the period of study, 43 major colorectal procedures were performed on 37 women. The most common colorectal procedure was low rectal resection (n=22; 59%) followed by anterior rectal resection (n=7; 19%) and sigmoid resection (n=4; 11%). Five (14%) patients underwent Hartmann's procedure. In three (8%) patients, a diverting loop ileostomy was created. ConclusionLow rectal resection during debulking procedures for gynaecological cancers with peritoneal carcinomatosis can safely be performed by an experienced surgeon without a diverting stoma.
