  Purpose
Haemorrhoidal artery ligation operation (HALO) is an operation that ties off vessels to piles. This study examines whether the ultrasound (doppler) is necessary to guide this tying off or not.

Condition Intervention
Piles Bleeding Procedure: HALO

Study Type: Observational
Study Design: Observational Model: Case-Control
Time Perspective: Prospective
Official Title: Haemorrhoidal Artery Ligation Operation; is Doppler Necessary?

Further study details as provided by Guy Nash, Poole Hospital NHS Foundation Trust:

Primary Outcome Measures:
  • Improvement of rectal bleeding [ Time Frame: 3-6 months ]

Secondary Outcome Measures:
  • Satisfaction with the HALO procedure with or without doppler guidance [ Time Frame: 3-6 months ]

Enrollment: 150
Actual Study Start Date: January 2010
Study Completion Date: March 2013
Primary Completion Date: December 2012 (Final data collection date for primary outcome measure)
Groups/Cohorts Assigned Interventions
Doppler
Those patients where the doppler was randomised to be on
Procedure: HALO
Ligation of haemorrhoidal arteries
Non doppler patients
those with no doppler guidance
Procedure: HALO
Ligation of haemorrhoidal arteries

Detailed Description:
HALO (haemorrhoidal artery ligation operation) has proved to be a popular and effective treatment for bleeding piles. Currently the HALO is a Doppler guided procedure though when the Doppler mechanism does not function it has been noted that the results are similar. This prompts the question does the Doppler guide the operation to tie off the important vessels to shrink he piles, or can the vessels that underlie the visible piles be treated without Doppler. Professor Phillips from St.Marks has reviewed the protocol and agrees that it is well designed and worthwhile.
