ABSTRACT
From April 2017 to April 2018, three male patients aged 46-71 years with large area burns were treated in our hospital. Acute acalculous cholecystitis (AAC) symptoms of the patients began to appear 15-81 days after injury. AAC was diagnosed 24-81 days after injury. Ultrasound-guided percutaneous transhepatic cholecystostomy was performed 26-82 days after injury. The symptoms subsided in 2 patients, and cholecystectomy was performed in 1 patient with gallbladder perforation 94 days after injury. The patients were cured and discharged 41-118 days after injury. No recurrence of cholecystitis occurred during 8-9 months of follow-up after discharge.
ABSTRACT
Objective To observe the efficacy of different degrees of portal vein ligation on portal pressure and liver regeneration of the unligated lobe in rats.Methods Seventy-two healthy male SpragueDawley rats were randomly divided into three groups:group A (sham,n =24);group B (n =24) undergoing 70％ portal vein ligation;group C (n =24) undergoing 90％ portal vein ligation.And then the portal pressure and liver regeneration rate (HRR) of the unligated lobe were detected immcdiately and postoperatively at each observation time point in each group.The serum alanine aminotransferase (ALT),aspartate aminotransferase (AST),hepatic proliferating cell nuclear antigen (PCNA) were compared at each observation time point,and the histological changes were observed by HE staining.Results The HRR of the unligated lobe in group B and group C increased obviously postoperatively at each time point,and the HRR in group C was significantly higher than that in group B [(220.1 ± 4.3) ％,(246.3 ± 5.6) ％,(261.4 ±2.3)％ vs (128.2 ±3.7)％,(143.4 ±8.7)％,(150.7 ±7.0)％,P＜0.05].The serum ALT and AST increased obviously on day 1 and then gradually declined,and the serum ALT and AST in group C was significantly higher than those in group B on day 1 [(821.7 ± 158.3) U/L,(1 372.0 ± 376.2) U/L vs (398.6 ± 80.4) U/L,(860.4 ± 80.0) U/L,P ＜ 0.05].The immediate portal pressure in both groups were obviously increased postoperatively and then gradually declined,and the portal pressure in group C was higher than that in group B at each observation time point [(23.5 ± 1.1)cmH2O,(18.8 ±0.9)cmH2O,(17.8±1.0)cmH2O,(16.6 ±1.0)cmH2O,(15.9±1.3)cmH2O vs (17.4 ±1.0)cmH2O,(16.5 ±1.2)cmH2O,(15.3±1.0)cmH2O,(10.2±1.2)cmH2O,(10.0±1.1)cmH2O,P＜0.05].ThePCNA index in group C was higher than that in group B on day 1 and3 [(21.5 ±1.1)％,(28.2±1.3)％ vs (12.8 ± 2.1) ％,(18.8 ± 1.9) ％,P ＜ 0.05].More foca1 necrosis of the unligated lobe were observed in group C on day 1,which were more than those in group B.Conclusion Higher degree of portal vein ligation could cause higher portal pressure,which leads to the greater regeneration of the unligated lobe.
