Doppler-guided Haemorrhoidal Artery Ligation With Suture Mucopexy vs. Suture Mucopexy Alone

February 20, 2015 updated by: Felix Aigner, Medical University Innsbruck

Doppler-guided Haemorrhoidal Artery Ligation With Suture Mucopexy vs. Suture Mucopexy Alone for the Treatment of Grade III Haemorrhoids: A Prospective-randomised Controlled Trial

Novel minimally invasive techniques were established for prolapsing haemorrhoids to minimise the drawbacks of the golden standard of haemorrhoidal treatment, conventional haemorrhoidectomy techniques. Ligation techniques, such as Doppler-guided haemorrhoidal artery ligation (DG-HAL), were introduced to reduce the arterial inflow of the AVP and thus prevent the haemorrhoidal zone from being part of the continence system. Apart from inappropriate application of this surgical alternative for higher grade haemorrhoids, high recurrence rates of up to 38% after DG-HAL are due to technical failure of the ligation technique itself. This is a prospective randomised controlled trial to evaluate the efficacy of additional Doppler-guided ligation of submucosal haemorrhoidal arteries in patients with symptomatic grade III haemorrhoids.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

All consecutive patients with symptomatic grade III haemorrhoids are randomly allocated to one of the two study arms: (A) DG-HAL with mucopexy or (B) mucopexy alone. Endpoints are pain, faecal incontinence, bleeding, residual prolapse and vascularisation of the anorectal vascular plexus. Vascularisation of the anorectal vascular plexus is assessed by transperineal contrast enhanced ultrasound.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Experimental: DG-HAL with mucopexy
Mucopexy with DG-HAL is performed using a specific device consisting of a proctoscope equipped with a Doppler probe and a light source. The proctoscope model in our study has a sliding part comprising the operating window and Doppler probe for better proximal and distal movement without repositioning the proctoscope during mucopexy.
Device: mucopexy +/- Doppler-guided haemorrhoidal artery ligation
Mucopexy with or without DG-HAL is performed using a specific device consisting of a proctoscope equipped with a Doppler probe and a light source. The proctoscope model in our study has a sliding part comprising the operating window and Doppler probe for better proximal and distal movement without repositioning the proctoscope during mucopexy.
Active Comparator: mucopexy alone
Mucopexy without DG-HAL is performed using the same specific device consisting of a proctoscope equipped with a Doppler probe and a light source as described above.
Device: mucopexy +/- Doppler-guided haemorrhoidal artery ligation
Mucopexy with or without DG-HAL is performed using a specific device consisting of a proctoscope equipped with a Doppler probe and a light source. The proctoscope model in our study has a sliding part comprising the operating window and Doppler probe for better proximal and distal movement without repositioning the proctoscope during mucopexy.

Study Major Dates

Study Start

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.

Primary Completion (Actual)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
