Abstract:
Objective:To study the clinical results of personalized surgical treatment for portal hypertension based on portal venous hemodynamics.Methods:A retrospective study was performed on patients with portal hypertension who underwent surgical treatment from January 2016 to December 2020 at the People’s Hospital of Ningxia Hui Autonomous Region and Wuhai People’s Hospital. Of 229 patients included into this study, there were 156 males and 73 females, with age of (4±11) years old. Portal vein CT and ultrasound doppler examination were performed preoperatively and portal vein manometry and ultrasound doppler examination were performed intraoperatively to evaluate portal venous hemodynamics. Based on the evaluation results, different surgical treatments were adopted. Postoperative complications and results of the operations were recorded. Long-term outcomes were evaluated by the rate of recurrence of gastroesophageal varices which was classified as disappearance, mild, moderate and severe according to endoscopic findings.Results:All the 229 patients completed the operations successfully. All together 13 operative treatments were used: (1) simple splenectomy ( n=11); (2) devascularization ( n=176), including 86 patients with splenectomy combined with extensive devascularization, 44 patients with splenectomy combined with selective devascularization and with preservation of paraesophageal veins, 39 patients with splenectomy combined with selective devascularization and reconstruction of spontaneous portosystemic shunt (34 patients with selective devascularization and reconstruction of spontaneous gastrorenal shunt and 5 patients with selective devascularization and reconstruction of spontaneous splenorenal shunt), 4 patients with secondary devascularization for variceal recurrence and 3 patients with devascularization and preservation of spleen; (3) shunt procedures were performed in 42 patients including 21 patients with splenectomy combined with coronary renal shunt, 11 patients with splenectomy combined with coronary-caval shunt, 6 patients with distal splenorenal shunt, 2 patients with proximal splenorenal shunt combined with devascularization, 1 patient with right gastroepiploic vein-inferior vena cava shunt and 1 patient with trans-inferior mesenteric vein coronary renal shunt. There were no operative deaths. The Clavien-Dindo grade 3 and above postoperative complication rate was 6.6% (15/229). Two hundred and eight patients were followed up for 6-60 months, with a median follow-up of 38 months. Severe recurrent varices were found in 21 patients (10.1%, 21/208), with 5 patients (2.4%, 5/208) presented with variceal bleeding. The rate of severe varices after selective shunting and selective devascularization by reconstructing the spontaneous portosystemic shunt (4.2%, 3/72) was significantly lower than that of the other devascularization procedures (13.7%, 17/124)(χ 2=4.53, P=0.033). Conclusion:Better clinical results were achieved by selecting the appropriate surgical procedures based on portal venous hemodynamic characteristics of patients. Selective shunting and selective devascularization by reconstructing the spontaneous portosystemic shunts significantly reduced the recurrence rate of severe varies.
