Frequency of Post-Operative Fecal Incontinence and Healing Rate in Patients with Open and Closed Lateral Internal Anal Sphincterotomy

Abstract

OBJECTIVES This study aims to compare the frequency of fecal incontinence and healing rate in patients treated with Open Internal Anal Sphincterotomy (OIAS) and Closed Lateral Internal Anal Sphincterotomy (CLIAS). METHODOLOGY This randomized control trial was carried out in the Department of Surgery Hayatabad Medical Complex, Peshawar Pakistan from Feb 2019 to Feb 2020. Eighty-four patients were assigned to the open method in Group B while eighty-four patients were allocated to the closed method in Group A (using blade 11) through the randomized control trial method. Fecal incontinence and healing rate were observed on the 7 th postoperative day. SPSS 23.0 software was used to analyse the data. RESULTS In group A out of a total of 84 patients, 96% of patients were in category A, 4% of patients were in category B, and no patients were in categories C and D. In group B out of 84 patients, 96% of patients were in category A while 4% patients were in category B and no patients were in category C and D. The total faecal incontinence in Group B (open method) was 21% while total fecal incontinence in Group A (closed method) was only 4% that is a clear dierence between the two groups. In group A (closed method) out of 84 patients, 2 patients (2.38 %) showed delayed healing while 82 patients (97.61 %) showed normal healing. In group B (open method) 7.4% of patients showed delayed healing with a signicance p level of 0.04 while 92.85 showed normal healing. CONCLUSION Fecal incontinence was less in closed Lateral Anal Sphincterotomy due to the use of blade 11 while it was higher in open internal anal sphincterotomy. Similarly, the healing rate was signicantly higher in the closed method while delayed healing was seen in the open method.
