Chronic Anal Fissure

Benign perianal diseases such as chronic anal fissure, hemorrhoidal disease, and cryptoglandular anal fistula may negatively affect female sexual function through pain, bleeding, discharge, discomfort, and impairment in quality of life. Although improvement in male sexual function after surgery for benign anorectal disorders has been reported, data regarding female sexual function remain limited. This prospective observational cohort study aims to evaluate changes in Female Sexual Function Index (FSFI) scores following surgical treatment of benign perianal diseases. Female patients undergoing surgery for chronic anal fissure, hemorrhoidal disease, or cryptoglandular anal fistula will be assessed preoperatively and at postoperative 3 and 6 months using the FSFI, Cleveland Clinic Incontinence Score (CCIS/Wexner), and Visual Analog Scale (VAS). The primary objective is to determine whether female sexual function improves following surgical treatment. Secondary objectives include evaluating the relationship between symptom improvement, continence status, pain reduction, and changes in female sexual function.

This prospective randomized controlled trial compares three lateral internal sphincterotomy (LIS) techniques in patients with chronic anal fissure refractory to medical treatment: (1) Spasm-Controlled LIS (serial small sphincterotomies using an anal calibrator until 30 mm anal caliber is achieved, under local anesthesia plus sedation), (2) LIS up to the Fissure Apex (spinal or general anesthesia), and (3) LIS up to the Dentate Line (spinal or general anesthesia). The primary outcomes are fissure healing rate and fecal incontinence incidence at 12 months, assessed using the Wexner Incontinence Score. Secondary outcomes include postoperative pain (VAS), recurrence rate, patient satisfaction, and complications. A total of 150 patients (50 per group) will be enrolled and followed for 12 months.

This study will evaluate the effectiveness of hyperbaric oxygen therapy (HBOT) on treating emerging indications (i.e., conditions that have shown to potentially benefit from HBOT) using the Multicenter Registry for Hyperbaric Oxygen Treatment. The study team aims to collect ongoing data on how well HBOT treats these emerging indications, and to add these data to the growing HBO Registry. The research team hypothesizes that HBOT will result in improvements of the condition of the various emerging indications.

This clinical trial is being conducted by investigators who are colorectal surgeons. Eligible study participants will receive the experimental treatment E-CEL UVEC cells by direct injection into the anal fissure. The study is being conducted to determine if E-CEL UVEC cell injections will be safe and would have any effects on healing of the anal fissure.

The purpose of this study is to improve treatment outcomes for patients with chronic anal fissure.

The goal of this observational study is to learn how a common surgery called lateral internal sphincterotomy (LIS) affects people with chronic anal fissures, a painful tear near the anus. The study will look at whether this surgery helps lower problems like pain and incontinence, and how it affects quality of life and mental health. The main questions the study aims to answer are: Does LIS surgery lower the rate of incontinence one year after surgery? Does it improve quality of life, reduce pain, and increase patient satisfaction? Participants will: Have surgery for chronic anal fissure called LIS. Complete short surveys about pain and mental health at 1 week, 3 months, and 12 months. Answer questions about bowel function, incontinence and daily life at 3 and 12 months. Researchers will follow about 300 adults at hospitals across the Turkey. This study will help improve future treatment decisions and make surgery safer and more effective.
