Comparison between Open Lateral Sphincterotomy and Posterior Midline Sphincterotomy with Fissurectomy in Treatment of Chronic Anal Fissure

Abstract

Objective: to compare the outcomes between two methods of treating chronic anal fissure; open lateral internal sphincterotomy (LIS) with fissurectomy versus posterior midline sphincterotomy (PIS) with fissurectomy, in terms of post-operative complications.

Study design: Randomized control trial

Place and duration: surgery department of Nishtar Hospital Multan from 10th February 2019 to 9th February 2020 in one year duration.

Methodology: Patients presented at outpatient department of hospital and diagnosed as chronic anal fissure were enrolled in study and divided into two groups for treatment. Group A was treated with open lateral sphinectomy with fissurectomy and group B was treated with posterior midline sphinectomy with fissurectomy. SPSS version 23 was used for data analysis.

Results:In LIS Group, the most common post-operative complication was infection 34.8%. The most common complication in PIS Group was also infection 77.8%. The differences were statistically significant for infection (p=0.000), bleeding (p=0.008) and bruising (p=0.000).

Conclusion: No differences was observed between lateral internal sphinectomy and posterior midline spinectomy in term of healing rates, symptomatic pain relief and the side effect occurrence after surgeries.
