Defunctioning colostomy for low anterior resection: A selective approach

Seventy‐seven consecutive low anterior resections of the rectum were performed with a selective approach to the use of a defunctioning colostomy. A defunctioning colostomy was performed in seven patients (9 per cent) where there was concern about the anastomosis due to difficult dissection (three), incomplete doughnuts (three) and tension on the anastomosis (one). The mean level of the tumour in the defunctioned group was 7±6 cm. Clinical anastomotic leakage occurred in two patients (3 per cent) in the non‐defunctioned group, both of which were controlled with subsequent transverse colostomies. There were no perioperative deaths. Selective defunctioning of low colorectal anastomoses can produce low rates of anastomotic dehiscence while reducing the morbidity associated with a temporary stoma.
