Abstract
Introduction Rubber band ligation is a minimally invasive outpatient hemorrhoid treatment with
low cost, low complication rates, and rapid realization. It is performed with the
aid of an anoscope and uses a rubber ring that surrounds the hemorrhoidal nipple,
causing compression of the vascular structures of the tissue, leading to necrosis
and remission of the hemorrhoid. No device for training this essential procedure for
treating this pathology has been identified in the literature. Therefore, we aim to
develop a low-cost simulator for training hemorrhoidal rubber ligation.
Methods The model was constructed using PVC pipe wrapped in neoprene fabric. Hemorrhoidal
nipples and the pectineal line were also simulated using fabric and sewing threads.
The procedure is performed with conventional anoscope and ligature forceps.
Conclusion The device in question is a low-cost simulation model designed to train the skills
required to perform a rubber band ligation and review the basic anatomy of the anal
canal during anoscopy. Given these qualities, the model can be used for academic training
due to its low cost and simplicity of application.
