Abstract
Background
Patients with hepatic schistosomiasis are at high risk of gastroesophageal variceal bleeding, which is highly torrential and life threatening. This study aimed to assess the effects of splenectomy on patients with schistosomiasis-induced variceal bleeding, especially those influences related to overall survival (OS) rate.
Methods
From January 2005 to December 2018, 112 patients with schistosomiasis-induced varices were enrolled. In that period, all the patients with hepatic schistosomiasis who received endoscopic treatment for primary and secondary prophylaxis of gastroesophageal variceal bleeding were found eligible. The patients were divided into splenectomized group (n = 44, 39.3%) and control group (n = 68, 60.7%).
Results
Multivariate regression analysis of OS showed that splenectomy, hepatic carcinoma, and times of endoscopic treatment were independent prognostic factors for OS. Kaplan–Meier analysis revealed that the 5-year OS rate was 82.7% in splenectomized group versus 53.2% in control group (P = 0.037). The rate of no recurrence of variceal bleeding during 5-year (56.8% vs. 47.7%, P = 0.449) indicated that there was no significant difference between the two groups. Patients who received splenectomy had increased risk of portal vein thrombosis (52.3% vs. 29.4%, P = 0.012) and decreased proportion of severe ascites (20.5% vs 50.0%, P = 0.002).
Conclusion
Splenectomy prior to endoscopic treatment provides a superior long-term survival for patients with schistosomiasis-induced variceal bleeding.
