Outcomes of stapler repair with anastomosis for stoma prolapse

Purpose: The published data on the outcomes of an operative repair for stoma prolapse are limited. This study aimed to clarify the long-term outcomes of stapler repair with anastomosis for stoma prolapse. Methods: Twenty-four patients (15 men, median age 64 years, range 33–88 years) undergoing 25 stapler repairs with anastomosis were prospectively registered, and their medical records were retrospectively reviewed. Results: The median length of prolapse was 10 cm (range 5–22). Stoma prolapse repair was performed by means of 16 loop colostomies, four end colostomies, three loop ileostomies, and one end ileostomy. A stapler was used 4.6 times on average (range 4–8). The average operative time and bleeding were 40.8 (range 15–75) min and 40 (range 0–214) mL, respectively. No mortality and morbidity were observed after surgery. A recurrence of stoma prolapse was reported in only one of 25 repairs (4%) at the proximal limb of loop ileostomy during a median follow-up period of 1 year (range 1–120 months). However, a new stoma prolapsed in one untreated limb of loop stoma. Conclusions: Stapler repair with anastomosis is a safe and minimally invasive treatment option for stoma prolapse with a low recurrence. However, the effectiveness of reparing stoma prolapse on the proximal limb of loop ileostomy might be limited.
