Garfinkle R, et al. - In this systematic review and meta-analysis, the pooled incidence of postoperative ileus (POI) after loop ileostomy closure was determined in addition to seeking risk factors associated with its development. Inclusion criteria were met by 67 studies including 9528 patients. Researchers identify POI as an important complication after loop ileostomy closure. They noted variation in its incidence by its definition: studies with a robust definition of POI (n = 8) demonstrated the highest estimate of POI while studies that did not report an explicit POI definition (n = 38) demonstrated the lowest estimate. Factors most commonly correlated with POI after loop ileostomy closure were small bowel anastomosis technique (hand-sewn) and interval time from ileostomy creation to closure (longer time).
