Aim:
Doppler-guided haemorrhoidal artery ligation (DGHL) has experienced wider uptake and has recently received National Institute for Health and Clinical Excellence (NICE) approval in the UK. A systematic review of the literature was conducted to assess its safety and efficacy.
Method:
This review was conducted in keeping with PRISMA guidelines. MEDLINE, EMBASE, Google Scholar and Cochrane Library databases were searched. Studies describing DGHL as a primary procedure and reporting clinical outcome were considered. Primary end-points were recurrence and postoperative pain. Secondary end-points included operation time, complications and reintervention rates. Studies were scored for quality with either Jadad score or NICE scoring guidelines.
Results:
Twenty-eight studies including 2904 patients were included in the final analysis. They were of poor overall quality. Recurrence ranged between 3% and 60% (pooled recurrence rate 17.5%), with the highest rates for grade IV haemorrhoids. Postoperative analgesia was required in 0-38% of patients. Overall postoperative complication rates were low, with an overall bleeding rate of 5% and an overall reintervention rate of 6.4%. The operation time ranged from 19 to 35 min.
Conclusion:
DGHL is safe and efficacious with a low level of postoperative pain. It can be safely considered for primary treatment of grade II and III haemorrhoids.
