Comparison of post-operative bleeding incidence in laser hemorrhoidoplasty with and without hemorrhoidal artery ligation: a double-blinded randomized controlled trial

BMC Surg. 2022 Apr 21;22(1):146. doi: 10.1186/s12893-022-01594-z.

ABSTRACT

INTRODUCTION: The effectiveness of hemorrhoidal artery ligation supplementation in reducing the incidence of post laser hemorrhoidoplasty bleeding has not been investigated.

METHODS: This was a double-blind, randomized controlled trial comparing post-operative bleeding incidence in patients undergoing laser hemorrhoidoplasty (LHP) only versus LHP with hemorrhoidal artery ligation (HAL). Outcome measures included post-operative bleeding and its severity (i.e. verbal rating scale and Clavien-Dindo classification), presence of perianal swelling and pain score (visual analog score) at 1-day, 1-week and 6-weeks post-operatively. Statistical tests were performed and a value of P < 0.05 was considered significant.

RESULTS: Seventy-six patients were randomized. There was no difference in median operating time. The bleeding incidence was highest at 1-week post-operatively (17.1%), and decreased to 1.3% at 6-weeks. There was no significant difference in bleeding incidence between both groups at any of the measured timepoints (P > 0.05). Severity of bleeding and incidence of post-operative perianal swelling were similar in both groups (P > 0.05). There was no difference in median pain scores.

CONCLUSION: Supplementation of HAL to LHP does not reduce the post-operative bleeding incidence. LHP is sufficient as a stand-alone procedure for treating haemorrhoids.

TRIAL REGISTRATION: National Registration Number is NMRR-15-1112-24065 (IIR). The trial start date was 1st January 2015 with the ClinicalTrials.gov identifier and registration number as NCT04667169.
