LAUSR

Introduction: Low anterior resection (LAR) is the standard procedure for distal rectal cancer allowing anal sphincter preservation. Anastomotic leakage remains one of the most dangerous complications following LAR and its management is difficult. Aim: This study reviews our experience of LAR with and without protective ileostomy (PI). Methods: One hundred ninety-nine patients undergoing LAR resection for low rectal cancer in this centre during the period 2015-2019 were divided retrospectively into two groups. Group A underwent rectal resection and coloanal/rectal anastomosis with diverting ileostomy and group B without ileostomy. Results: Among our patients, 20 had a covering ileostomy (stoma group);179 did not (control group). The stoma group comprised 14 men and 6 women ranging in age from 36 to 89 years (mean, 64.2 ± 10.5 years). Conventional v. minimally invasive surgery was 6/14. Anastomotic leakage occurred in 16/179 (8.93%) patients without a PI, and in 6/20 (30%) with a stoma (Tab. I.). Of the 16 patients experiencing an anastomotic leak, 3 (18.75%) from Group A and 5 (83.33%) from Group B were classified as Grade B leakage and were treated conservatively. As many as 13/16 (81.25%) in Group A and 1/6 (16.77%) in Group B were classified as Grade C leakage and required emergency surgery. Conclusion: These results do not show a preventive effect on the occurrence of anastomotic leakage in low anterior resection, but may significantly reduce the need for further surgery due to septic complications in the early postoperative period. Selection of patients for protective ileostomy requires great care as its creation and closure are associated with severe complications.
