A pragmatic multicentre randomised controlled trial comparing stapled haemorrhoidopexy with traditional excisional surgery for haemorrhoidal disease: the eTHoS study

Abstract

BackgroundHaemorrhoids are a benign anorectal condition and are highly prevalent in the UK population. Treatments involve clinic-based procedures and surgery. The surgical procedures available include stapled haemorrhoidopexy (SH) and traditional haemorrhoidectomy (TH), and over 25,000 operations are performed for haemorrhoids annually in the UK. The disease is therefore important both to patients and to health service commissioners. Debate remains as to which of these surgical procedures is the most clinically effective and cost-effective.ObjectiveThe aim of this study was to compare the clinical effectiveness and cost-effectiveness of SH with that of TH.DesignA large, open two-arm parallel-group pragmatic multicentre randomised controlled trial involving 32 UK hospitals and a within-trial cost–benefit analysis. A discrete choice experiment was conducted to estimate benefits (willingness to pay).ParticipantsPatients with grades II–IV haemorrhoids who had not previously undergone SH or TH were included in the study.InterventionsParticipants were randomised to receive either SH or TH. Randomisation was minimised at 1 : 1, in accordance with baseline EuroQol-5 Dimensions, three-level version (EQ-5D-3L) score, haemorrhoid grade, sex and centre, via an automated system.Main outcome measuresThe primary outcome was area under the quality-of-life curve measured using the EQ-5D-3L descriptive system over 24 months, and the primary economic outcome was the incremental cost-effectiveness ratio. Secondary outcomes included disease-specific quality of life, recurrence, complications, further interventions and costs.ResultsBetween January 2011 and August 2014, 777 patients were randomised (389 to receive SH and 388 to receive TH). There were 774 participants included in the analysis as a result of one post-randomisation exclusion in the SH arm and two in the TH arm. SH was less painful than TH in the short term. Surgical complications were similar in both arms. EQ-5D-3L score was higher for the SH arm in the first 6 weeks after surgery, but over 24 months the TH group had significantly better EQ-5D-3L scores (–0.073, 95% confidence interval –0.140 to –0.006;p = 0.0342). Symptoms and further interventions were significantly fewer in the TH arm at 24 months. Continence was better in the TH arm and tenesmus occurred less frequently. The number of serious adverse events reported was 24 out of 337 (7.1%) for participants who received SH and 33 out of 352 (9.4%) for those who received TH. There were two deaths in the SH arm, both unrelated to the eTHoS (either Traditional Haemorrhoidectomy or Stapled haemorrhoidopexy for haemorrhoidal disease) study. Patient preference did not seem to influence the treatment difference. SH was dominated by TH as it cost more and was less effective. The net benefit for the TH arm was higher than that for the SH arm.LimitationsNeither the participants nor the assessors were masked to treatment assignment and final recruitment was slightly short of the total target of 800. There were also substantial missing follow-up data.ConclusionsWhile patients who received SH had less short-term pain, after 6 weeks, recurrence rates, symptoms, re-interventions and quality-of-life measures all favoured TH. In addition, TH is cheaper. As part of a tailored management plan for haemorrhoids, TH should be considered over SH as the surgical treatment of choice for haemorrhoids refractory to clinic-based interventions.Future workPerform an updated meta-analysis incorporating recently conducted European trials [eTHoS, HubBLe (haemorrhoidal artery ligation versus rubber band ligation for the management of symptomatic second-degree and third-degree haemorrhoids) and LingaLongo (Cost-effectiveness of New Surgical Treatments for Haemorrhoidal Disease)].Trial registrationCurrent Controlled Trials ISRCTN80061723.FundingThis project was funded by the National Institute for Health Research (NIHR) Health Technology Assessment programme and will be published in full inHealth Technology Assessment; Vol. 21, No. 70.

Still a Case of “No Pain, No Gain”? An Updated and Critical Review of the Pathogenesis, Diagnosis, and Management Options for Hemorrhoids in 2020

“…That said, some have called into question the long-term efficacy of stapled haemorrhoidopexy in treating haemorrhoids [72], with meta-analyses concluding that the technique is associated with higher recurrence rates than conventional haemorrhoidectomy, thus necessitating reoperation [73,74]. This appears to be a problem especially for stapled haemorrhoidopexies performed for fourth-degree haemorrhoids [75], emphasising the importance of patient selection when using this technique.…”

Results of the double-blind randomized controlled trial comparing laser hemorrhoidoplasty with sutured mucopexy and excisional hemorrhoidectomy

“…The most effective procedure-excisional hemorrhoidectomy-causes the most pain to the patient [1]. Two recent large randomized trials compared excisional hemorrhoidectomy with stapled hemorrhoidopexy [2], and rubber band ligation with hemorrhoidal artery ligation [3]. The first trial conclusively proved that excisional hemorrhoidectomy is more effective and cheaper than stapled hemorrhoidopexy.…”
