Clinical and manometric evaluation of women with chronic anal fissure before and after internal subcutaneous lateral sphincterotomy

objective: to evaluate clinical and manometric parameters of chronic anal fissure females undergoing lateral internal sphincterotomy (lis). methods: a total of eight women with chronic anal fissure who underwent lis were included in this study. the preoperative assessment was performed one week before surgery and included general and anorectal examination, anorectal manometry, and jorge wexner questionnaire. the post operative follow up was made every 15 days until complete healing. jorge wexner questionnaires and anorectal manometry were repeated at 1 month and 3 months after the surgery. time to healing, manometric changes and complications were assessed. results: all patients had preoperative increased anal resting pressure. the resting pressures and anal canal length were significantly decreased 3 months after surgery. patients' complaints of itching and bleeding were also reduced. fissures healed in 7 patients and median healing time was 45 days. no complications were observed due to the procedure. one patient had transient incontinence to flatus. conclusion: lateral internal sphincterotomy provided clinical improvement and reduced resting pressure of the internal anal sphincter in women with chronic anal fissure.
