This workshop is part of the courses on medical-surgical endoscopy organised by the Catalan Society of Medical-Surgical Digestive Endoscopy. The aim of such courses is to train and update surgeons and digestive specialists or residents on minimally invasive techniques. Its mixed medical and surgical design allows specialists to learn from each other. The content of the courses is theoretical-practical, with an initial theoretical part in person and online, and a practical part, which will provide specific technical skills.
