Deloyers Technique for Restoration of Bowel Continuity Following Extended Left Hemicolectomy: A Comprehensive Analysis of 97 Cases and Literature Review.

Background: Deloyers technique addresses challenges in restoring bowel continuity following extended left hemicolectomies. Despite being first described in 1958, the technique remains underutilized, with limited data on long-term outcomes.

Objective: To evaluate the indications, surgical and functional outcomes of Deloyers technique and review existing literature.

Design: Using a prospectively maintained database, patient demographics and perioperative data were collected. A telephone interview was conducted to assess bowel function and statistical analysis identified factors affecting bowel function.

Settings: Single tertiary care center.

Patients: Patients that underwent Deloyers technique from January 1995 to February 2023.

Results: A total of 97 patients were included. Most common indications were colorectal cancer (50.5%) and diverticular disease (21.6%). In 53.6% of cases DT was performed at re-operations and in 70.1% a diverting loop ileostomy was created. Early surgical complications occurred in 7.2% of patients, including five anastomotic leaks, one colonic conduit ischemia and one small bowel obstruction. Late complications occurred in 8.2%, including 6 anastomotic strictures and 2 chronic leaks. There was no perioperative mortality. A total of 40 patients were interviewed and reported an average of 3.5 bowel movements per day and 0.5 at night, 17.5% used bowel stoppers and 52.5% of patients reported that their bowel function did not impact their quality of life. Previous radiotherapy and anastomosis less than eight cm from the anal verge were associated with having four or more bowel movements per day (p < 0.01).

Main outcomes measures: Postoperative morbidity and bowel function.

Limitations: Retrospective analysis of a heterogeneous group of patients with different pathologies and indications for surgery.

Conclusion: Deloyers technique is a safe and effective alternative for restoring bowel continuity after extended left hemicolectomy. Postoperative functional results are generally satisfactory, with more favorable outcomes noted in patients with higher anastomoses and those who have not undergone prior pelvic radiotherapy.
