ABSTRACT
Thrombosed external hemorrhoids are a complication of hemorrhoids characterized by severe pain, swelling, and lump formation due to acute venous engorgement. Treatment options remain controversial, with limited evidence guiding the choice between surgical and conservative approaches. PubMed, Embase, and Cochrane Library databases were searched from inception to December 2024 to identify clinical trials comparing surgery with conservative treatment in thrombosed external hemorrhoids. Statistical analyses were performed using Review Manager 5.4.1 with a random-effects model. Heterogeneity was assessed using the I2 test. We included six studies with a total of 851 patients, of whom 390 (45.8%) underwent surgical treatment. Surgical treatment was associated with a lower risk of recurrence compared to conservative management (RR 0.49; 95% CI 0.26-0.91; P < 0.05; I2 = 54%). However, there were no significant differences in the risk of bleeding between the groups (RR 0.96; 95% CI 0.27-3.44; P = 0.95; I2 = 60%). Subgroup analyses of the excision surgery group revealed no differences between approaches. Our main findings indicated no significant difference in bleeding between surgery and conservative treatment groups. However, operative management is associated with significantly lower recurrences, which should be the preferred choice.
