Abstract

Purpose: Laparoscopic right hemicolectomy (LRH) can be performed with an intracorporeal anastomosis (IA) or extracorporeal anastomosis (EA). It is not clear which technique is best. This study evaluated the impact of each anastomosis technique on perioperative safety and postoperative evolution.
Methods: We performed a retrospective study at a tertiary colorectal surgery center. All patients who had an elective LRH from 2015 to 2019 were analyzed according to the anastomosis technique used.
Results: In total, 285 patients were included in the study. IA was performed in 64 patients (22.5%). Mean operative time was longer in the patients with IA (IA, 160±31 minutes vs. EA, 138±42 minutes; P<0.001). No differences were observed in intraoperative complications, time to first bowel movement, length of stay, reoperation, or rehospitalization. Time to first flatus was longer in the patients with IA (P=0.049). At 30 days after surgery, there were no differences in the frequency of anastomotic leak (IA, 0% vs. EA, 2.3%; P=0.59), bleeding (IA, 3.1% vs. EA, 2.7%; P>0.99), or intraabdominal abscess (IA, 0% vs. EA, 0.5%; P>0.99). During follow-up, we noted more incisional hernias in patients with EA (IA, 1.6% vs. EA, 11.3%; P=0.01) and a trend toward more hernia in patients with EA in multivariate analysis (hazard ratio, 7.13; P=0.06). Anastomosis technique had no influence on recurrence.
Conclusion: For LRH, both IA and EA are safe, with a low incidence of complications when performed by experienced surgeons. IA may be associated with a lower incidence of incisional hernia.
