Analysis of risk factors for delayed bleeding after semi-clo
Male sex, drinking history, more than four hemorrhoid piles, and laxative usage were independent risk factors for delayed post-hemorrhoidectomy bleeding (DPHB) in patients undergoing semi-closed hemorrhoidectomy.

The aim of this study was to determine the incidence of delayed post-hemorrhoidectomy bleeding (DPHB) after hemorrhoidectomy using a semi-closed procedure. Investigators also investigated risk factors associated with DPHB.

This retrospective study enrolled a total of 1645 consecutive patients with symptomatic grade II to IV hemorrhoids who underwent a semi-closed procedure. All patients underwent a semi-closed procedure with submucosal feeding vessel ligation, a method commonly performed at the institution.

A total of 1645 patients underwent semi-closed hemorrhoidectomy.

--Critically, 24 patients experienced DPHB. Of these patients, 13 experienced stump bleeding, whereas 11 experienced marginal bleeding.

- Multivariate analysis showed that male sex, drinking history, more than four hemorrhoid piles, and laxative agents were independent risk factors for DPHB.

--The risk of stump bleeding was significantly associated with male sex, more than four hemorrhoid piles, and laxative usage.

--Conversely, the risk of marginal bleeding was significantly associated with drinking history and more than four hemorrhoid piles.

In conclusion, Male sex, drinking history, more than four hemorrhoid piles, and laxative usage were risk factors associated with DPHB in patients undergoing semi-closed hemorrhoidectomy. The risk factors for stump bleeding included male sex, more than four hemorrhoid piles, and laxative usage. In contrast, the risk factors for marginal bleeding were drinking history and more than four hemorrhoid piles.
