Low albumin level and longer interval to closure increase the early complications after ileostomy closure

Loop ileostomy has an important role in mitigating the serious effects of anastomotic leakage in colorectal surgery. However, the morbidity and mortality associated with ileostomy reversal cannot be overlooked. We investigated the possible risk factors for complications following ileostomy reversal.

All patients who underwent loop ileostomy closure between 2008 and 2017 at Inje University Busan Paik Hospital were identified. Medical records on patient characteristics, preoperative management, surgical techniques, postoperative management, chemotherapy/radiotherapy, and complications were retrospectively analyzed in a prospectively collected database.

A total of 354 patients underwent loop ileostomy closure. The overall complication rate was 23.7%, with Clavien-Dindo grade I as the most common (15.8%), 5.6% in grade II, 2.2% in grade III-V, and three patients died. The two most common complications were wound infection (11.6%) and small bowel obstruction (4.8%). In univariable and multivariable analyses, closure technique or chemotherapy did not affect the outcome, but low serum albumin <3.5 g/dL (OR 7.248, CI 2.416-22.838, p < 0.001) and longer interval to ileostomy closure (OR 1.977, CI 1.167-3.350, p = 0.0113) were independent contributing factors for morbidities of ileostomy closure.

Closure technique or chemotherapy did not affect the complication of ileostomy closure. However, serum albumin <3.5 g/dL and a longer interval to ileostomy closure were identified as risk factors for morbidity of ileostomy closure. These two factors should be corrected and planned before ileostomy closure.
