Filter by:Background: Constipation is a common problem, affecting up to 20% of the population during their lifetime. Some patients respond poorly to standard treatments such as laxatives. A subgroup of these have dyssynergic defaecation where the muscles that control bowel movements fail to relax during pushing, preventing evacuation of stools. Currently, the mainstay of treatment requires muscle retraining by a therapist using a technique called biofeedback. Patients in whom biofeedback has failed are left with few options, one of which includes Botox injection into the pelvic floor muscles involved in the defaecation process. However, current method of injection is inaccurate and often requires anaesthesia. The investigators propose a novel technique for Botox delivery which reduces the risks and associated costs. Objectives: 1. The primary objective is to demonstrate technical feasibility of percutaneous infracoccygeal Botox injection as an alternative to transanal puborectalis muscle injection for the treatment of dyssynergic defaecation. 2. The secondary objectives are to assess the safety and acceptability of this technique, and to derive pilot clinical effectiveness data to inform future studies. Methods: The investigators will carry out Botox injection into the puborectalis muscle under ultrasound guidance in the outpatient department. This will be done by percutaneous injection below the coccyx where the puborectalis has been demonstrated to be easily accessible. An electromyography of the puborectalis is obtained before the injection to demonstrate proof of mechanism. The investigators will collect data using a combination of questionnaires, patient baseline data, and anorectal physiology test results before and after the treatment. Outcomes: - Feasibility: procedure duration, rate of identification of puborectalis by ultrasound scan and pre-injection EMG, procedure limitations, and successful injection rate - Safety: rate of adverse events - Acceptability: patient pain and comfort, willingness to undergo repeat procedure - Preliminary data on effectiveness: Cleveland Clinic constipation score, anorectal physiology test results
To assess whether HR-ARM (High resolution Anorectal Manometry) performed in the more naturalistic / physiological upright, seated position on a commode provides a more valid assessment of anorectal function and simulated defecation than the same test performed in the standard, left lateral position
Comparative study between surgical and non surgical treatment of anismus in patients with symptoms of obstructed defecation. Anismus is a significant cause of chronic constipation. This study came to compare the results of BFB training , BTX-A injection and PDPR in the treatment of anismus patients. Patients and methods: Seventy two anismus patients fulfilled Rome II criteria for functional constipation were included in this study. All patients underwent anorectal manometry, balloon expulsion test, defecography, and electromyography activity of the EAS. All patients had non relaxing puborectalis muscle.. The patients were randomized into three groups. Group I patients received biofeedback therapy, two times per week for about 1 month. Group II patients were injected with BTX- A. Group 111 partial division of puborectalis was done. Follow up was conducted weekly in the first month then monthly for about 1 year.
This study aimed to evaluate the safety and symptomatic outcomes achieved with Stapled Transanal Rectal Resection (STARR) compared to biofeedback training in patients with obstructed defecation syndrome (ODS).
