Abstract
Purpose : A low pelvic anastomosis is associated with a substantial risk of leakage. A defunctioning stoma (DS) reduces the clinical anastomotic leak rate and the need for re-operation, but stoma closure has its own risk of morbidity and mortality. This study aims to audit morbidity and mortality after loop ileostomy (LI) closure. Patients and methods : The medical records of 197 consecutive patients who underwent closure of a defunctioning LI between August 2003 and July 2008 were reviewed. Postoperative morbidity and mortality were recorded. Results : Transverse closure of the enterotomy was performed in 149 patients (75.6%), segmental enterectomy with hand-sewn end-to-end anastomosis in 26 (13.2%) and stapled side-to-side anastomosis in 22 (11.2%). Overall postoperative morbidity and mortality were 32.0% and 0.5%, respectively. The surgical complication rate was 30.5%, including prolonged ileus (11.2%), small bowel obstruction (4.1%), anastomotic leak (3.0%) and wound infection (4.6%). Surgical complications were more frequent in male patients (p = 0.005). Prolonged ileus was more frequent when the interval to stoma reversal exceeded 12 weeks (14.3% versus 3.5%; p = 0.02). The incidence of complications was not influenced by the closure technique. Nineteen patients (9.6%) required re-operation for anastomotic leak (n = 8), wound infection (n = 1), small bowel obstruction (n = 3) and incisional herniation (n = 7).
Conclusion : LI closure is associated with clinically relevant morbidity and mortality. This association should be taken into account in the context of a routine DS policy and should be part of the patient’s information.
