Colour doppler-guided haemorrhoidal artery ligation: A possible evolution of transanal haemorrhoidal dearterialisation

Introduction. Haemorrhoids are a very common disease, with a great economic burden. Many treatments have been developed for trying to solve the problem, being the standard not yet found. In 1995, Doppler-guided haemorrhoidal artery ligation was introduced, aiming to reduce postoperative pain and complications. In this work, an evolution of the aforementioned surgical technique was described. Materials and Methods.183 patients treated with standard Doppler-Guided Haemorrhoidal Artery Ligation were statistically compared with 225 patients dealt with Colour Doppler-Guided Haemorrhoidal Artery Ligation. The procedures were performed under local anaesthesia with patients in lithotomy position. A…
