“…Pelvic abscess is usually the result of an anastomotic leak. Even though there have been few studies which have directly compared the anastomotic complication rate between the two groups, the reported anastomotic complication rates in the colo-anal anastomosis group range from 9.7% to 20% [70,72,74,76,83,86,88], and from 1.2% to 10.5% [1,6,8,56,90,91] in the colonic J-pouch group, showing a trend towards superiority in the latter setting. Hallbook and Sjodahl [74] reported a randomized trial comparing coloanal anastomosis to colonic J-pouch.…”
