Descriptive Information
Brief Title  ICMJE RCT Comparing Conventional Haemorrhoidectomy With Laser Haemorrhoidoplasty
Official Title  ICMJE A Randomised Controlled Trial Comparing Conventional Open Haemorrhoidectomy and Laser Haemorrhoidoplasty in the Treatment of Symptomatic Haemorrhoids: COHLAH Trial
Brief Summary

Haemorrhoids or piles are the most common colorectal condition in the local population. Patients often present with bleeding with bowel movement or anal discomfort, both of which causes significant anxiety and stress. For symptomatic sizeable piles, the treatment of choice still remains the conventional open excision (COH). However, this technique carries with it a significant risk of bleeding and pain immediately after the operation, leading to some period of discomfort for the patients. The laser haemorrhoidoplasty procedure (LAH) has been shown in preliminary studies to have less pain, and less complications compared to COH. This study aims to directly compare these two techniques in a local Asian population.

The investigators would be conducting a single-centre RCT simultaneously comparing the conventional open Milligan-Morgan haemorrhoidectomy (COH) and the laser haemorrhoidoplasty procedure (LAH) for the treatment of symptomatic grade ll-lV haemorrhoids. Primary outcomes will be post-operative pain while secondary outcomes include post-operative bleeding, readmission and/or reoperations, haemorrhoid-related quality of life (QoL) results and recurrence of symptoms up to a year post procedure

Study Type  ICMJE Interventional
Study Phase  ICMJE Phase 2
Phase 3
Study Design  ICMJE Allocation: Randomized
Intervention Model: Parallel Assignment
Intervention Model Description:
The investigators would be conducting a single-centre RCT simultaneously comparing the conventional open Milligan-Morgan haemorrhoidectomy (COH) and the laser haemorrhoidoplasty procedure (LAH) for the treatment of symptomatic grade ll-lV haemorrhoids.
Masking: Double (Participant, Outcomes Assessor)
Masking Description:

Allocation is provided through calling the study administrator at time of Examination under Anaesthesia. Thus, the participant is blinded to the procedure. There will also be no cross-over from one study arm to another.

An independent research administrator, not part of the randomisation process, will also contact the patient 3 months and 1 year after the procedure as mentioned above.
