ABSTRACT
BACKGROUND:
Liver cirrhosis is the highest risk factor for hepatocellular carcinoma (HCC) worldwide. However, etiological therapy is the only option in cirrhosis patients to decrease the HCC risk. The aim of this study was to explore whether laparoscopic splenectomy and azygoportal disconnection (LSD) decreases the risk of HCC for patients with cirrhotic portal hypertension (CPH).METHODS:
Between April 2012 and April 2021, we identified 595 CPH patients in our hepatobiliary pancreatic center who were diagnosed with gastroesophageal variceal bleeding and secondary hypersplenism, and performed a 10-year retrospective follow-up. Inverse probability of treatment weighting (IPTW) was used to adjust for potential confounders, weighted Kaplan-Meier curves and logistic regression to estimate survival and risk differences.RESULTS:
According to the method of therapy, patients were divided into LSD (n = 345) and endoscopic therapy (ET; n = 250) groups. Kaplan-Meier analysis revealed that patients who underwent LSD had higher survival benefit with those who underwent ET (P < 0.001). At the end of the follow-up, ET group was associated with a higher HCC incidence density compared with LSD group (28.1/1000 vs 9.6/1000 person-years; Rate ratio [RR] 2.922, 95% confidence intervals [CI] 1.599-5.338). In addition, logistic regression analyses weighted by IPTW revealed that, compared with ET, LSD was an independent protective predictor of HCC incidence (odds ratio [OR] 0.440, 95% CI 0.316-0.612; P < 0.001).CONCLUSIONS:
Considering the better postoperative survival and the ability to prevent HCC in CPH patients with gastroesophageal variceal bleeding and secondary hypersplenism, LSD is worth popularization in situations where liver donors are scarce.Key words
