Transanal haemorrhoidal dearterialisation with mucopexy versus stapler haemorrhoidopexy: A randomised trial with long-term follow-up

摘要

INTRODUCTION The present study aimed to compare the long-term results of transanal haemorrhoidal dearterialisation (THD) with mucopexy and stapler haemorrhoidopexy (SH) in treatment of grade III and IV haemorrhoids. METHODS One hundred and twenty-four patients with grade III and IV haemorrhoids were randomised to receive THD with mucopexy (n=63) or SH (n=61). A telephone interview with a structured questionnaire was performed at a median follow-up of 42 months. The primary outcome was the occurrence of recurrent prolapse. Patients, investigators and those assessing the outcomes were blinded to group assignment. RESULTS Recurrence was present in 21 patients (16.9%). It occurred in 16 (25.4%) in the THD group and 5 (8.2%) in the SH group (p=0.021). A second surgical procedure was performed in eight patients (6.4%). Reoperation was open haemorrhoidectomy in seven cases and SH in one case. Five patients out of six in the THD group and both patients in the SH group requiring repeat surgery presented with grade IV haemorrhoids. No significant difference was found between the two groups with respect to symptom control. Patient satisfaction for the procedure was 73.0% after THD and 85.2% after SH (p=0.705). Postoperative pain, return to normal activities and complications were similar. CONCLUSIONS The recurrence rate after THD with mucopexy is significantly higher than after SH at long-term follow-up although results are similar with respect to symptom control and patient satisfaction. A definite risk of repeat surgery is present when both procedures are performed, especially for grade IV haemorrhoids.
