Chronic anal fissures: Open lateral internal sphincterotomy result; a case series study
Abstract
Introduction Anal fissure are defined as a tear in the skin of the anal canal distal to dentate line. Although still there are controversies about the exact management, lateral sphincterotomy is promising. The aim of this series is to present the outcome of lateral sphincterotomy for internal anal sphincter in term of patient satisfaction and complication. Patient and methods A prospective single cohort study, 190 patients, who were undergone lateral sphincterotomy for internal anal sphincter from 2010 to 2014, were analyzed. The operation was performed as a day case procedure. The median duration of follow up was 5 years (ranging from 3 to 6). The data were analyzed using the Statistical Package for Social sciences (SPSS) version 22. Descriptive statistic was used to describe findings. Results Forty three males (22.6%) and 147 females (77.4%) with a mean ± SD of age of 31.19 ± 7.78 years. Constipation was reported in 152 (80%) patients, bleeding in 131 (68.6%) cases, and pain in 142 (74.7%) patients. The median duration of the disease was 20 months (ranging from 1 to 30 months). Post-operatively, patient satisfaction was high (98.4%) with only 3 cases (1.6%) of recurrence. Conclusion: lateral sphincterotomy for internal anal sphincter, along, is the procedure of choice for management of CAF because it is effective and it can cure the disease in nearly all patients with good patient satisfaction.
How strong is the evidence?
Evidence Hub reads this as a case series, done in people. Its evidence level is 5 of 5 (Very low · case / narrative / animal / in vitro / in silico). Case reports, narrative reviews, and animal, cell or computer-model studies give the weakest evidence for human health. Reported size: 190 participants or records.
