Comparative Outcomes of Inj Botox Alone vs Inj Botox Combined With Fissurectomy and Anoplasty in the Management of Chronic Anal Fissure

Pakistan108 participantsStarted 2026-06-03

Plain-language summary

Chronic anal fissure is a common benign anorectal condition characterized by severe pain during defecation, rectal bleeding, and reduced quality of life. Injection Botox is a widely used sphincter-preserving treatment that produces temporary relaxation of the internal anal sphincter and promotes fissure healing. However, healing rates with injection Botox alone are variable and recurrence remains a concern. This prospective comparative trial aims to compare the effectiveness and safety of injection Botox alone versus injection Botox combined with fissurectomy and anoplasty in adults with chronic anal fissure. The study will evaluate healing rate, pain relief, time to healing, recurrence, postoperative complications, continence outcomes, and patient satisfaction. A total of 108 eligible patients with chronic anal fissure will be enrolled and allocated to one of the two treatment groups. Participants will be followed after treatment to assess clinical outcomes. The results of this study are expected to provide evidence regarding the optimal sphincter-preserving treatment approach for chronic anal fissure and help improve patient care and quality of life.

Questions worth asking your doctor

Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.

1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.

Questions for the trial coordinator

The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.

1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?

A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
