Spleen conserving laparoscopic azygoportal disconnection for cirrhotic portal hypertension / 中华普通外科杂志

ABSTRACT

Objective To investigate the feasibility and safety,and short-term therapeutic effect of laparoscopic azygoportal disconnection without splenectomy for cirrhotic portal hypertension (PLT count ＞ 50 × 109/L).Methods Clinical data of 48 patients with bleeding portal hypertension and secondary hypersplenism (PLT count ＞ 50 × 109/L) undergoing laparoscopic splenectomy and azygoportal disconnection (LSD,n =26) vs.laparoscopic azygoportal disconnection (LD,n =22) between January 2014 and August 2015 were analyzed.Results Operative time (82 ± 29) min,intraoperative blood loss 20(10-50) ml,days of postoperative fever 0(0-3) d,rate of postoperative fever 10/22,postoperative hospital stay (7.0 ± 1.3) d,and WBC counts (3.8 ± 1.6) × 109/L,PLT counts 64 (49-88) × 109/L,and the incidence of portal vein thrombosis on POD 7 (14％),were significantly less in LD group than in LSD group [(180±41) min,80(20-500) ml,2(0-4) d,(22/26),(10.8 ±3.0) d,(9.1 ±3.1) × 109/L,156 (78-630) × 109/L,(42％)],(t =9.637,Z =-4.746,Z =-2.314,x2 =8.224,t =5.794,t =7.785,Z=-5.508,x2 =4.742,all P ＜ 0.05).Immune function was better in LD group than in splenectomy group at postoperative month 3.The serum proportion of CD4 + (58 ± 11) and the CD4 +/CD8 + ratio (1.9 ±0.7) at postoperative month 3 were significantly higher after LD than after LSD [(43 ± 14),(1.2 ± 0.9)],(t =-3.755,t =-2.509,all P ＜ 0.05).Conclusion Laparoscopic azygoportal disconnection without splenectomy is safe and effective for esophagogastric variceal hemorrhage and moderate hypersplenism (PLT ＞ 50 × 109/L) secondary to portal hypertension.
