Endoscopic excision for internal and mixed hemorrhoids: a retrospective case series of short-term outcomes

This study aimed to investigate the short-term clinical outcomes and safety of endoscopic excision for the management of internal and mixed hemorrhoids.

A retrospective analysis was conducted on 20 patients with Grade II to Grade IV internal or mixed hemorrhoids who underwent endoscopic excision at Zhoushan Hospital between January 2024 and December 2024. All patients had complete follow-up data.

At 3 and 6 months after surgery, the treatment effectiveness rate was 100%, and both postoperative satisfaction and acceptance rates were 100%. No severe postoperative complications occurred, and no bleeding or infection was observed. Mild pain developed in three patients, a transient sensation of anal heaviness and distension occurred in one patient, and temporary urinary retention occurred in one patient, which resolved after local hot compress therapy. Postoperative pathological examinations confirmed that the resected anorectal masses demonstrated changes consistent with hemorrhoidal tissue.

Endoscopic excision for internal and mixed hemorrhoids is a safe and effective therapeutic approach. It provides significant symptom relief, yields high postoperative satisfaction and acceptance among patients, and allows for definitive pathological confirmation of the nature of the resected anorectal tissue.
