Article abstract: Introduction & Objective: Anal fissure is a common problem that causes significant morbidity in a young and otherwise healthy population. In this study we aimed at comparing the two surgical treatments: Closed lateral internal subcutaneous sphincterotomy, and Open lateral internal subcutaneous sphincterotomy.
Materials & Methods: 60 patients with signs and symptoms of chronic anal fissure who had referred to Ekbatan Hospital of Hamadan for surgical treatment, were included in this study. They were randomly divided into two groups of 30 patients, One group underwent Open Lateral internal subcutaneous sphincterotomy (group A), and the other group underwent close Lateral internal subcutaneous sphincterotomy (group B). Afterwards the questionnaires were filled in concerning the patients` demographic characteristics and the duration of their problem and their post surgical conditions such as: healing and back to work time and days with pain, using patients’ words and the physical exam performed by the physician during the patient’s stay in hospital and later on by interviewing the patients six month after the operation. The data were analyzed by SPSS 10 software and were compared by T-test and chi square tests.
Results: Average healing time in the two groups was 21.53±3.55 days in group A and 7.7±2.1 days in group B, which are statistically different (P<0.001).Patients went back to work 4.39±0.8 days after operation in group A, and 3.27±1 days after operation in group B (P<0.001). Also average days with pain after surgical treatment was significantly different in the two groups (P=0.02). Hematoma was not discovered and bleeding did not take place in the first 48 hours post surgery in any of the patients.
Conclusions: We suggest that open lateral internal sphincterotmy is associated with less post operative discomfort and healing times.
