AbstractNearly half of patients undergoing low anterior rectal cancer resection have a functional sequelae after straight coloanal or low colorectal anastomoses (SA), including low anterior rectal resection syndrome, which combines stool fragmentation, urge incontinence, and incontinence. SA are responsible for anastomotic leakage rates of 0 to 29.2 per cent. Adding a colonic reservoir improves the functional results while reducing anastomotic complications. These colonic reservoir techniques include the colonic J pouch (CJP), transverse coloplasty (TC), and side-to-end anastomosis (STEA) procedures. The aim of this literature review was to compare the functional outcomes of these three techniques from a high level of evidence. CJP with a 4- to 6-cm reservoir is a good surgical option because it reduces functional impairments during the first year, and probably up to 5 years, but is not always feasible. TC appears to perform as well as CJP, is achievable in over 95 per cent of patients, but still with some doubts about a higher anastomotic leakage rate and worse functional outcomes. STEA appears equivalent to CJP in terms of morbidity and even better functional outcomes. STEA, with a terminal side segment size of 3 cm, is feasible in the majority of nonobese patients, combines good functional results, has low anastomotic leakage rates, and is easy to complete.
