Trial summary

Idiopathic hypertensive anal canal is a fact and already exists presented by anal pain aggravated by defecation. It can be managed safely by closed lateral sphincterotomy but chemical sphincterotomy had a minor role in its management. Read more about this study

About this study

Idiopathic hypertensive anal canal is a fact and already exists presented by anal pain aggravated by defecation. It can be managed safely by closed lateral sphincterotomy but chemical sphincterotomy had a minor role in its management.

Read the detailed description

Patient and methods: Sixty three patients complaining of anal pain without any anal pathology and 10 healthy volunteers were examined. All patients underwent clinical evaluation, neurological examination, anorectal manometry, and measurement of pudendal nerve terminal motor latency (PNTML). All patients with hypertensive anal canal were randomized into three groups. Group I (surgical group) underwent closed lateral sphincterotomy LS, group II using nitroglycerine ointment (GTN) and group III received injection of botulinum toxin in internal sphincter. Post procedures data were recorded at follow up period.

Being tested
lateral internal sphincterotomy (LIS), Glycerin trinitrate (GTN), botulinum toxin injection (BTX A)
Keywords

What participants receive

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

  • lateral internal sphincterotomy (LIS)Procedure or surgery

    closed lateral internal sphincterotomy was done under local anesthesia at 3 o'clock in lithotomy position reaching up to the dentate line.

  • Glycerin trinitrate (GTN)Drug

    Also called GTN ointment

    All were instructed to apply the GTN ointment 0.2 % twice a day to the edge and just inside the anal canal for 8 week course.

  • botulinum toxin injection (BTX A)Drug

    Also called BTX A

    All were injected with botulinum toxin injection (BTX- A) in the left lateral position; anesthesia was not required. A volume of 0.5 ml of dissolved toxin, i.e., 100 u Dysport, is injected in each patient. The injection is given with an insulin syringe fitted with a needle size of 21 gauze and 3.75 lengths. Injection into the IAS, with the patients awake in the left -lateral position in the outpatient clinic in the 3 and 9 o'clock position.

What is being measured

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

  1. Effect of Closed Lateral Sphincterotomy and Chemical Sphincterotomy on Hypertensive Anal Canal

    effect of closed lateral sphincterotomy and chemical sphincterotomy on hypertensive anal canal, anal manometery

    Measured: one year

  2. Relieve of Anal Pain

    using a visual analog scale (VAS) with which each patients noted the severity of pain at each evaluated time using a linear between zero (no pain) and 10 ( severe pain)

    Measured: one year after the procedure

Questions about this trial

What is this clinical trial studying?

A study testing lateral internal sphincterotomy (LIS), Glycerin trinitrate (GTN) and botulinum toxin injection (BTX A) in people with Hypertensive Anal Canal, run by Mansoura University at 1 site in Egypt.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 1 inclusion and 2 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Are results available for this study?

Yes. Results are posted in the registry (first posted 25 Jun 2009). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Effect of Closed Lateral Sphincterotomy and Chemical Sphincterotomy on Hypertensive Anal Canal (time frame: one year). The study lists 2 primary outcomes in all. 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 NCT00927849, which also lists 4 linked publications.

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

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
