Colonic invagination anastomosis in surgery of complicated forms of diverticular disease

Abstract

AIM: to evaluate the prospects of using a colorectal invaginated anastomosis in patients with complicated diverticular disease (CDD).PATIENTS AND METHODS:during the period from 2014 to 2020, colorectal invaginated anastomosis, was used in 42 patients: 18 patients with CDD and 20 patients with colorectal cancer for stoma closure after Hartmann’s procedure. The comparison group consisted of 24 patients with CDD and 20 patients with colorectal cancer for stoma closure after Hartmann’s procedure: colorectal anastomosis was created here using traditional double-row handsewn technique. All patients underwent surgery with open access, while the primary anastomosis was performed in 20 (47.6%) patients, and in 22 (52.4%) patients of the group underwent stoma takedown.RESULTS: no anastomosis leakage developed in the main group. Moreover, the presence of single small diverticula with a diameter of 2–3 mm near the area of the anastomosis was not an indication to extend the resection borders. In the control group, in 13 (54.2%) patients, small diverticula were detected in the anastomosis are as well and required to expand the proximal border of resection. In this group, anastomosis leakage occurred in 2 (6.8%) patients with diverticular disease and required Hartmann’s procedure.CONCLUSION: the colorectal invaginated anastomosis is justified for patients with CDD during stoma takedown because it minimizes the risk of anastomosis leakage.
