About this study

Official title: Comparative Study Between Surgical and Non Surgical Treatment of Anismus in Patients With Symptoms of Obstructed Defecation

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.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • BFDOther

    Also called BIOFEEDBACK RETRAINING

    The investigators used pressure based biofeedback training, using a perfused eight-channel polyvinyl catheter with a compliant balloon at the tip

  • PDPRProcedure or surgery

    Also called PARTIAL DIVISION OF PUBORECTALIS

    A 2-3 cm curved incision is made on either side of the anal canal along its posterolateral aspect, each about 2.5 cm distance from the anal verge Fig(2). After that dissection in ischiorectal fossa was done till reaching the puborectalis sling from outside i.e. extrasphincteric approach . Using a right angle forceps the puborectalis sling is lifted up, guided by the contralateral index finger in the anal canal Fig(3). Nearly the inner half of puborectalis sling was divided on each side by using a scalpel NO. 11 Fig(4). Complete haemostasis was followed by skin closure without drain

  • BTX AOther

    Also called BOTILINUM TOXIN

    A vial of Dysport, 500 u, (Dysport, Ipsen, United Kingdom) is dissolved in 2.5 ml isotonic saline Fig(1). A volume of 0.5 ml of dissolved toxin, i.e., 100 u Dysport, is injected in each patient

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. improvement in bowel habit (regarding the straining severity, anorectal pain,number of weakly bowel movement,sensation of incomplete defecation and need of digitation or enema and using constipation score)

    Measured: 1 year

Secondary outcomes (1)
  1. per rectal examination,manometeric relaxation,balloon expulsion,defecogram,EMG examination of anal sphincter to monitor any change in paradoxical contraction,recurrences,incontinence,complication

    Measured: 1 year

What does the primary outcome measure?

improvement in bowel habit (regarding the straining severity, anorectal pain,number of weakly bowel movement,sensation of incomplete defecation and need of digitation or enema and using constipation score) (time frame: 1 year). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT00735605, which also lists 5 linked publications.

Does a listing mean the treatment is approved or proven to work?
