After low anterior resection for cancer, the incidence of the categories major, minor, and no low anterior resection syndrome were comparable in the stoma and the no-stoma groups. Incontinence for flatus and liquid stools was more commonly reported by patients who were randomly assigned to temporary stoma, as compared with those without, which may indicate an association between temporary stoma and impaired anorectal function.

Background: The aim was to assess factors influencing the timing of defunctioning stoma (DS) reversal following low anterior resection of rectum for cancer (LAR). Methods: All patients operated with LAR and a primary DS during a 9-year period were included. Reversal later than 120 days after LAR was considered as delayed. A DS not reversed within 2 years was considered as permanent.Results: In the present study, median age at LAR was 67 years, 45% were females, median body mass index was 25, 87% had American Society of Anesthesiologists class I or II, 64% had pre-operative radiotherapy, and 3% had cancer stage IV. A total of 79% (92/116) underwent stoma reversal, whereof 25% (23/92) were reversed within 120 days. The most common health-related reasons for delayed stoma reversal were adjuvant chemotherapy in 38%, symptomatic anastomotic leakage in 16% and other post-operative adverse events in 13%. In 35% delayed stoma reversal was because of low priority within the healthcare system. A total of 18% (20/110) never had their DS reversed (n = 11) or had their DS converted to a permanent end colostomy (n = 9). Major risk factors for permanent stoma were stage IV cancer in 55%, and symptomatic anastomotic leakage in 30%. Conclusion: One fourth of the patients had their defunctioning stoma reversed within 120 days. The most common identifiable medical reasons for delayed stoma reversal were adjuvant chemotherapy and symptomatic anastomotic leakage, while in one out of three patients it was because of low priority by the healthcare provider.
Aim Low anterior resection of the rectum for cancer (LAR) entails a risk of symptomatic anastomotic leakage as well as impaired anorectal function, both of which may eventually result in the need for a permanent stoma (PS). The aim was to investigate the incidence of and risk factors for PS beyond 5 years following LAR. Methods Patients undergoing LAR and included in a multicentre trial with randomization to defunctioning stoma or not were followed for a median of 15 years. The reasons for a PS up to 5 years (PS ≤ 5 years) and beyond 5 years (PS > 5 years) were identified and compared. Risk factors for PS were analysed. Results Of all patients, 25% (57/232) had a PS. PS ≤ 5 years occurred in 19% (44/232) at a median of 12.5 months and PS > 5 years in 6% (13/232) at a median of 118 months following LAR. The main reason for PS ≤ 5 years was impaired anorectal function in 55% (24/44) and the main reason for PS > 5 years was pelvic sepsis related to the colorectal anastomosis in 46% (6/13). The major risk factor for PS was symptomatic anastomotic leakage, which occurred in 56% (32/57) of patients with PS and 10% (17/175) of patients without PS (P < 0.001). Conclusion One-fourth of the patients who ended up with a PS had it fashioned beyond 5 years at a median of 10 years following LAR. Symptomatic anastomotic leakage was the major risk factor for PS, and impaired anorectal function was the main overall reason for a PS. What does this paper add to the literature? Following sphincter preserving total mesorectal excision surgery for rectal cancer, the risk of ending up with a permanent stoma is substantial, although this outcome is seldom reported beyond 5 years. The present study addresses this topic, and to our knowledge no study with a follow-up of 15 years has been published previously. Our study demonstrates an increasing risk for a permanent stoma even beyond 5 years, as well as a shift in the type of permanent stomas fashioned at this later stage. Furthermore, half of the permanent stomas created beyond 5 years were due to very late pelvic sepsis related to the low anastomosis.
