Reversal of left-sided colostomy utilizing single-port laparoscopy: single-center consolidation of a new technique

Considerable morbidity (10-14%) and even mortality (4-30%) have been reported after reversal of intestinal continuity following Hartmann's procedure. Feasibility of and advantages in reducing peri- and postoperative morbidity by utilizing single-port techniques through the colostomy site have been suggested before in small case series. The purpose of the present prospective observational study is to evaluate the outcomes of reversal of intestinal continuity using single-port access in a relatively large consecutive cohort.

All consecutive patients undergoing single-port reversal of left-sided colostomy (SPRLC) between November 2012 and 2018 were included in the present study. Primary outcome was 30-day postoperative complication rate. Secondary outcomes were postoperative length of stay, single-port success rate, and surgical details like duration and conversion rates.

Of 85 procedures, 69.4% were without postoperative complications. No postoperative mortality was encountered. Superficial site infection is the most frequent complication and occurred in 22.4%, major complications classified as Clavien-Dindo grade 3 or above in 9.4% and anastomotic leakage in 3.5%. Median length of stay was 3.0 days (1-69), single-port success rate was 64.7%, and 15.3% was converted to an open procedure.

This study confirms the safety, feasibility, and the advantages of SPRLC. In centers with adequate laparoscopic experienced surgeons, this technique should be considered as a serious and attractive alternative to restore intestinal continuity in patients with left-sided end colostomy, especially in patients after open index surgery. More research must be done in a multicenter setting to evaluate the use and standardization of single-port technique in reversal of intestinal continuity procedures.
