Purpose: Delayed post-hemorrhoidectomy bleeding (DPHB) is a rare but serious complication. We investigated the incidence and risk factors of DPHB in patients undergoing hemorrhoidectomy using the LigaSure device or the Ferguson procedure. Methods: This retrospective study included 382 consecutive patients with symptomatic grades II to IV hemorrhoids who received either LigaSure (184 patients) or Ferguson (198 patients) hemorrhoidectomy procedures. Thirty-two patients who experienced DPHB after discharge were followed up. Results: Significantly fewer Ferguson group patients had DPHB compared to the LigaSure group (5.1% vs. 11.9%; P = 0.015). In the overall population, the risk of DPHB was higher in (1) males compared to that of females (OR = 3.39; 95% CI 1.50–7.69, P = 0.003); (2) in the LigaSure group compared to the Ferguson group (OR = 2.77; 95% CI 1.23–6.24, P = 0.01); and (3) in patients with constipation (OR = 6.59; 95% CI 2.73–15.89, P < 0.0001). Males in the LigaSure group had a significantly higher rate of delayed bleeding than those in the Ferguson group (20% vs. 5.8%, P = 0.004); no significant differences were found in females (4.9% vs. 4.5%, P = 0.878). Subgroup analysis showed that in males, risk of DPHB increased significantly with postoperative constipation (OR = 4.73, 95% CI 1.45–15.43, P = 0.010) and the LigaSure procedure (OR = 3.99, 95% CI 1.37–11.62, P = 0.011). In females, the risk of DPHB was significantly associated with postoperative constipation (OR = 8.80, 95% CI 2.24–34.54, P = 0.002). Conclusions: The LigaSure procedure and constipation are independent risk factors for DPHB in patients undergoing hemorrhoidectomy and can be used as predictors of outcome.
