Objective: To compare the results of surgical treatment of chronic anal fissure resistant to conservative management, after anal fissurectomy or lateral internal sphincterectomy. Methodology: One hundred forty five patients with chronic anal fissure failed to heal with medical treatment admitted in the Department of Surgery Unit II Liaquat University Hospital Jamshoro Sindh Pakistan, from January 2007 to June 2009 were studied.
Urinary retention was noted in 3(2.06%) patients, 2(2.98%) in fissurectomy (F) and 1(1.28%) in lateral internal sphincterectomy (LIS) group.
Conclusion: In the treatment of chronic anal fissure lateral internal sphincterectomy is the best surgical technique with very few complications and better patient satisfaction.
The purpose of this study was to compare the results of fissurectomy (F) and lateral internal sphincterectomy (LIS) in terms of relief of symptoms, postoperative complications and recurrence.
In 78 patients lateral internal sphincterectomy was done, 28 patients (9 male, 19 female) had general anaesthesia, and 50 patients (35 male, 15 female) had spinal anaesthesia.
Additionally, endoscopic sphincterectomy has an associated morbidity rate of 10% and a mortality rate of up to 1%.
