An interventional study of RBL and Hemorrhoidectomy in Hemorrhoids, Hemorrhoids, Internal and PROM, sponsored by Proctos Kliniek. Status unknown at 9 sites in Netherlands. Open to participants aged 18 Years and older. Per ClinicalTrials.gov, last updated 2021-03-16.

Rationale: Haemorrhoidal disease is one of the most common anorectal disorders which affects nearly half of the general population1. Given the current numerous modalities the obvious question which needs to be answered is which treatment is the best. An interesting conclusion from a recent systematic review regarding operative procedures for haemorrhoidal disease is that all procedures have their own advantages and disadvantages. There is a need for evaluating treatment from the patient's point of view and transparency in surgical and non-surgical treatment outcome. So far there is no sufficiently large trial that meets that demand.
Objective: To establish the best treatment of patients with symptomatic haemorrhoids grade III: haemorrhoidectomy versus rubber band ligation (RBL). Patient bound effectiveness, clinical effectiveness and cost-utility of both treatments is compared; primary outcome is quality of life at 24 months measured with the EQ-5D-5L with Dutch rating and recurrence at one year post procedure. The assumption is that treatment with rubber band ligation is equally effective in comparison with haemorrhoidectomy in terms of quality of life.
Study design:Multicentre randomized controlled non-inferiority trial with cost-utility analysis. Two treatment protocols are compared: haemorrhoidectomy and rubber band ligation.
Study population: Patients aged ≥ 18 years with symptomatic haemorrhoids gr III. Patients are recruited in multiple clinics during 18-24 months.
Intervention: Participants are allocated to either rubber band ligation or haemorrhoidectomy.
Main study parameters/endpoints: Primary outcome measure is quality of life at 24 months measured with the EQ-5D-5L with Dutch rating and recurrence at one year post procedure. Secondary outcomes are: complaint reduction with proctology specific patient-related outcome measure (HSS, PROM, PROMHISS), vaizey score, resumption of work, pain (VAS), complications and recurrence at two years.

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

Rubber band ligation is performed by a suction device that allows a rubber band to be applied at the base of the haemorrhoid via a proctoscope. Maximal suction force used is 40 mmHg. A maximum of 3-4 bands are used per session. This rubber band constricts the blood supply causing it to become ischaemic before being sloughed approximately 1-2 weeks later. The resultant fibrosis reduces any element of haemorrhoidal prolapse that may have been present. No sedation is required for this day-care procedure. Patients are asked to administer an enema 2 hours prior to the procedure.
Procedure: RBL
There are two main excisional procedures currently carried out: open (Milligan and Morgan) and closed (Ferguson). Both have the intention of excising the haemorrhoidal cushions. The procedure is performed under either general or spinal anaesthesia in a day-care setting. Patients were asked to administer an enema 2 hours prior to the procedure.
Procedure: Hemorrhoidectomy

Health related quality of life
The EQ-5D-5L is a generic Health Related Quality of Life (HRQoL) measure, which is broadly used in economic evaluation. The instrument examines a patient's HRQoL on the day of the interview. It consists of the EQ-5D-5L descriptive system and the EQ-Visual Analogue Scale. The descriptive system comprises five dimensions: mobility, self-care, usual activities, pain/discomfort and anxiety/depression. Each dimension has five levels: no problems, slight problems, moderate problems, severe problems, and extreme problems. Responses to the 5 items result in a patient's health state that can be transformed into an index score representing health-related quality of life, ranging between 0 (death) and 1 (full health). These index scores are combined with length of life to calculate the QALY. The EQ-VAS records the patient's self-rated health with endpoints labelled 'the best health you can imagine' at the top and 'the worst health you can imagine' at the bottom.
Time frame: 24 months
Recurrence
Patient self reported assessment with a dichotomous question: "At the moment, do you feel your symptoms from your haemorrhoids are: (1) cured or improved compared with before treatment; or (2) unchanged or worse compared with before treatment?" Any patient who answers '1' but has required further treatment since the initial procedure will be reclassified as '2', identified via hospital records, their consultant and patient questioning
Time frame: at 12 months
In-hospital direct costs
with EQ-5D-5L and cost incremental analysis (iMCQ and iPCQ): The impact of disease on the ability of a person to perform work should be part of an economic evaluation when a societal perspective is applied. iMTA is highly experienced in methods for measuring and valuing productivity losses.The Productivity Costs Questionnaire (iPCQ) may be combined with the iMTA Medical Consumption Questionnaire (iMCQ), a generic instrument for measuring medical costs. The iMCQ includes questions related to frequently occurring contacts with health care providers and can be complemented with extra questions that are relevant for specific study populations.
Time frame: this will be asked at 6 weeks, 6, 12 and 24 months
