RESUMEN
Background: Hepatosplenic schistosomiasis (HSS) is one of the most common causes of portal hypertension in developing countries. Variceal bleeding is the most common cause of mortality during HSS. The objective of this study was to evaluate the efficacy of splenectomy associated with endoscopic variceal ligation (EVL) compared with EVL alone in preventing variceal bleeding in patients with HSS. Methods: This was a single-center, retrospective, case-control study. Between January 2015 and December 2019, a total of 59 patients with HSS who had at least one variceal bleeding episode and received EVL with or without splenectomy were identified and stratified. In this case-control design, 22 patients had splenectomy + EVL (case group) and 37 patients had EVL alone (control group). The main endpoints were the rate of variceal rebleeding and the mortality rate between the two groups. Results: The mean age of our patients was 39.92 ± 13.4 (19-75) years with a sex ratio of 1.8. The recurrence rate of variceal bleeding was significantly lower in the case group (splenectomy + EVL) than in the control group (EVL alone) (4.45% vs 27.2%, p = 0.041). There was no significant difference between the two groups in terms of mortality (4.54 vs 2.7%, p = 1.00). Conclusion: Splenectomy combined with EVL was effective than EVL alone in preventing variceal rebleeding in patients with HSS.
