title: Early closure of temporary loop ileostomies: a systematic review.
abstract: A temporary loop ileostomy is a common surgical procedure to protect colorectal anastomoses. The aim of this systematic review was to determine whether early closure of a defunctioning loop ileostomy (<2 weeks from index operation) is safe and reduces stoma-related morbidity. A systematic literature search was conducted using Ovid MEDLINE, EMBASE, Cochrane Collaboration, and the Cumulative Index to Nursing and Allied Health (CINAHL®) databases to identify all publications from January 1996 to March 2014 that reported the outcomes of early ileostomy closure. The following search terms (and their variations) were used as both medical subject headings (MeSH terms) and text words: ileostomy, surgical stoma, stoma, early, reversal, closure. No language restrictions were applied. The main outcomes of interest were stoma-related complications and postclosure complications. Studies that included pediatric patients (<18 years of age), small cohorts (<10 participants), case reports, conference abstracts, reviews, and letters; studies involving defunctioning colostomies or other types of small bowel stomas; and studies where results from closure of an ileostomy at >14 days could not be separated from early closure results were excluded. Where multiple studies were reported by the same institution and/or authors, only the most recent was included. This search strategy identified 4 studies (2 retrospective case series, 1 prospective nonrandomized study, and 1 randomized controlled trial), yielding a pooled population of 142 patients, ages 18-89 years old. Three studies reported indication for ileostomy; colorectal cancer accounted for 96 patients (78%). Time to ileostomy closure ranged from 8-14 days. No reported deaths were related to ileostomy closure. Wound infections were reported in 3 studies and were the most common complications, affecting 24 patients (19.8%). Of the 2 studies that reported ileostomy-related complications, 4 patients (3.6%) experienced a stoma-related complication before closure. Ileus or small bowel obstruction (SBO) occurred in 7 patients (4.9%). Compared to traditionally timed closure (8-12 weeks), reported stoma-related complication rates were lower in patients undergoing early closure. Both mortality and ileus/SBO rates also compare favorably with traditionally timed closure; however, wound infection rates appear to be increased. Additional studies to accurately define which individuals stand to benefit from early closure, as well as to further evaluate the impact of early ileostomy closure on quality of life and health care costs, are warranted.
