Bowel function after laparoscopic right hemicolectomy: a randomized controlled trial comparing intracorporeal anastomosis and extracorporeal anastomosis

Background The laparoscopic right hemicolectomy is the standard surgical treatment for right-sided colon cancer. The continuity of the digestive tract is restored through ileocolic anastomosis which can be performed extracorporeally or intracorporeally. The study aimed to compare both anastomotic techniques in laparoscopic right hemicolectomy. Materials and methods A single-blinded two-armed randomized control trial with 1:1 parallel allocation carried out from 2016 to 2020 in a single center. The follow-up period was 30 days. Compared interventions involved extracorporeal and intracorporeal ileocolic anastomosis in laparoscopic right hemicolectomy. The main outcome of the study was bowel recovery measured as the time to the first stool. Other outcomes involved the time to the first flatus, morbidity, and duration of surgery. Results One hundred and seventeen patients undergoing a laparoscopic right hemicolectomy with curative intent were eligible for the trial. Eight patients refused to participate. One hundred and two patients were analyzed, 52 in the intracorporeal group and 50 in the extracorporeal group. The groups did not differ in terms of cancer stage or body mass index, but did differ in age and sex. Intracorporeal anastomosis was associated with a shorter time to the first stool than extracorporeal, 32.8 h (26.0–43.7) vs. 41.7 (35.9–50.0), p = 0.017. There was no significant difference in the time to the first flatus, 30 h (23.2–42.3) vs. 26.6 h (21.8–37.3), p = 0.165. Similarly, overall complications did not differ (EC 12/50 vs. IC 10/52, p = 0.56). There were no differences in length of surgery, 190 min (150–230) and 190 min (180–220), p = 0.55. Conclusion Intracorporeal ileocolic anastomosis following laparoscopic right hemicolectomy results in slightly faster bowel recovery, with no differences in morbidity and duration of surgery.

37-year-old man presented to the emergency department with a three-hour history of severe, generalized abdominal pain. Computed tomography of abdomen revealed two distal ileoileal intussusceptions with high suspicion of 3 cm mass within the intussusception around the ileocecal region. Laparoscopic right hemicolectomy with extracorporeal ileocolic anastomosis which showed Meckel
