ABSTRACT
AIM: After extended left colectomy, traditional colorectal anastomosis is often not feasible because of insufficient length of the remaining colon to perform a tension-free anastomosis. Total colectomy with ileorectal anastomosis could be an alternative but this can lead to unsatisfactory quality of life. Trans-mesenteric colorectal anastomosis or inverted right colonic transposition (the so-called Deloyers procedure) are two possible solutions for creating a tension-free colorectal anastomosis after extended left colectomy. Few studies have reported their results of these two techniques and mostly via laparotomy. The aim of this study was to describe the trans-mesenteric colorectal anastomosis and the inverted right colonic transposition procedure via a laparoscopic approach and report the outcome in a series of 13 consecutive patients. METHOD: This was retrospective chart review of laparoscopic colorectal surgery with trans-mesenteric colorectal anastomosis or the inverted right colonic transposition procedure from January 2015 up to 2019. An accompanying video demonstrates these two techniques. RESULTS: Thirteen consecutive patients underwent either a laparoscopic trans-mesenteric colorectal anastomosis (n = 9) or an inverted right colonic transposition procedure (n = 4). One patient had intra-operative presacral bleeding that was stopped successfully without conversion. Two patients had a postoperative intra-abdominal abscess, but no anastomotic complications were recorded. The median number of bowel movements per day after 6 months was 2 (range 2-5). CONCLUSIONS: Trans-mesenteric colorectal anastomosis or the inverted right colonic transposition procedure is feasible laparoscopically. The now well-established classical advantages of the laparoscopic approach are associated with good functional outcome after these procedures.
