Loop ileostomy versus loop colostomy for fecal diversion after colorectal or coloanal anastomosis: a meta-analysis.
BACKGROUND: Sphincter-saving surgery for the treatment of middle and low rectal cancer has spread considerably when total mesorectal excision became standard treatment. In order to reduce leakage-related complications, surgeons often perform a derivative stoma, a loop ileostomy (LI), or a loop colostomy (LC), but to date, there is no evidence on which is the better technique to adopt.
METHODS: We performed a systematic review and meta-analysis of all randomized controlled trials until 2007 and observational studies comparing temporary LI and LC for temporary decompression of colorectal and/or coloanal anastomoses. Clinically relevant events were grouped into four study outcomes: general outcome measures: dehydratation and wound infection GOM construction of the stoma outcome measures: parastomal hernia, stenosis, sepsis, prolapse, retraction, necrosis, and hemorrhage closure of the stoma outcome measures: anastomotic leak or fistula, wound infection COM, occlusion and hernia functioning of the stoma outcome measures: occlusion and skin irritation.
RESULTS: Twelve comparative studies were included in this analysis, five randomized controlled trials and seven observational studies. Overall, the included studies reported on 1,529 patients, 894 (58.5%) undergoing defunctioning LI. LI reduced the risk of construction of the stoma outcome measure (odds ratio, OR = 0.47). Specifically, patients undergoing LI had a lower risk of prolapse (OR = 0.21) and sepsis (OR = 0.54). LI was associated with an excess risk of occlusion after stoma closure (OR = 2.13) and dehydratation (OR = 4.61). No other significant difference was found for outcomes.
CONCLUSION: Our overview shows that LI is associated with a lower risk of construction of the stoma outcome measures.
