Background
Laparoscopic splenectomy and azygoportal disconnection (LSD) is widely used for the treatment of esophagogastric variceal haemorrhage and hypersplenism owing to cirrhotic portal hypertension. However, whether LSD improves liver synthesis function and cirrhosis remains unclear. The aim of this study is to investigate the effect of LSD on liver synthesis function and cirrhosis based on a prospective 2-year follow-up study.
Methods
A total of 118 patients with cirrhotic portal hypertension who underwent LSD were included in this study. We analysed clinical data including routine blood parameters, liver function, liver-synthesised proteins (antithrombin III, protein S, and protein C), liver fibrotic markers (type IV collagen (IV-C), procollagen type III (PC-III), laminin, and hyaluronidase), portal vein diameter, and portal blood flow velocity.
Results
Postoperative portal vein diameter and portal blood flow velocity all showed gradual declines during the 2-year follow-up; compared with preoperative values, these were all significantly decreased from postoperative week (POW) 1 (all P < 0.001). Postoperative Child–Pugh scores and total bilirubin, albumin, international normalised ratio, antithrombin III, protein S, protein C, IV-C, PC-III, laminin, and hyaluronidase levels also all showed gradual improvements during the 2-year follow-up; compared with preoperative levels, these were all significantly improved from postoperative month (POM) 6, POW 1, POM 3, POM 3, POM 3, POM 6, POM 18, POW 1, POM 3, POM 24, and POM 18, respectively (all P < 0.05).
Conclusion
LSD not only decreases portal hypertension and improves liver function, it also enhances liver synthesis function and reduces liver fibrosis.
