Abstract
Purpose: The aims of this study were to identify the clinical characteristics of an anastomotic sinus and to assess the validity of delaying stoma closure in patients until the complete resolution of an anastomotic sinus. Methods: The subject patients are those who had undergone a resection of rectal cancer from 2011 to 2017, who had a diversion ileostomy protectively or therapeutically and who developed a sinus as a sequelae of anastomotic leakage. The primary outcomes that were measured were the incidence, management and outcomes of an anastomotic sinus. Results: Of the 876 patients who had undergone a low anterior resection, 14 (1.6%) were found to have had an anastomotic sinus on sigmoidoscopy or a gastrografin enema before their ileostomy closure. In the 14 patients with a sinus, 7 underwent ileostomy closure as scheduled, with a mean closure time of 4.1 months. The remaining 7 patients underwent ileostomy repair, but it was delayed until after the follow-up for the widening of the sinus opening by using digital dilation, with a mean closure time of 6.9 months. Four of those remaining seven patients underwent stoma closure even though their sinus condition had not yet been completely resolved. No pelvic septic complications occurred after closure in any of the 14 patients with an anastomotic sinus, but 2 of the 14 needed a rediversion due to a severe anastomotic stricture. Conclusion: Patients with an anastomotic sinus who had been carefully selected underwent successful ileostomy closure without delay. © 2019 The Korean Society of Coloproctology
