Latest Research Trends on the Management of Hemorrhoids

Abstract

Hemorrhoids manifest with a range of symptoms and severities, prompting the development of various conservative, interventional, and surgical treatments. Selecting the most suitable treatment for each case is challenging, especially with the continuous evolution of new methods. This review aims to advance hemorrhoid treatment and research by exploring recent developments over the last five years. Conservative approaches have focused on isolating active ingredients from traditional herbal remedies to create new products and understand their mechanisms. In office-based treatments, advanced devices such as modified rubber band ligation and polymer clips with stronger binding forces have been introduced. Polidocanol in foam form has shown promise in sclerotherapy, while infrared coagulation is being replaced by alternative energy-based methods. Additionally, endoscopic office treatments and embolization of hemorrhoidal vessels via angiography are increasingly used as safer options for patients with high surgical risks or bleeding issues. Stapled hemorrhoidopexy has shifted to partial resection instead of complete circular resection, and hemorrhoidal artery ligation techniques have been reported to be effective when combined with stapled hemorrhoidopexy or excisional hemorrhoidectomy in severe cases. Evidence is growing that hemorrhoidal artery ligation remains effective even without Doppler guidance. With ongoing research into various methods, there is a need for scientific comparison and evaluation of their advantages and disadvantages, standardization of indicators and treatment protocols, and cost-effectiveness considerations. Surgeons should offer well-informed options and explanations to patients, based on a comprehensive understanding of available treatments.
