ABSTRACT
Objective To investigate the expressions and the significance among the three markers TGF β1,Survivin and Caspase-3 in intrahepatic bile duct tissues in patients with intrahepatic bile duct stones.Method Total of 130 paraffin section of intrahepatic bile duct tissue were collected at Department of Pathology,The 904th Hospital of Joint Logistic Support Force of PLA from 2013 to 2018.Total of 50 patients with intrahepatic bile duct stones complicated with bile duct strictures (the stenosis group),40 patients with intrahepatic bile duct stones with chronic inflammation (the inflammation group),and 40 patients with normal liver tissues (the normal control group) were included in this study.The expressions of TGF β1,Survivin and Caspase-3 in liver tissues were detected by immunohistochemistry and compared among the 3 groups to find their correlations with the clinicopathological features of the disease of the patients.Results TGF β1 was expressed in 72.0％ of the patients in the stenosis group,37.5％ in the inflammatory group,and 15.0％ in the normal control group.The differences among the groups were significant (P ＜ 0.05);Survivin was expressed in 78.0％ of the patients in the stenosis group,47.5％ in the inflammatory group,and 25.0％ in the normal control group.The differences among the groups were significant (P ＜ 0.05);Caspase-3 was expressed in 10.0％ of the patients in the stenosis group,42.5％ in the inflammatory group,and 75.0％ in the normal control group.The differences among the groups were significant (P ＜ 0.05).Within the stenosis group,TGF β1 was negatively correlated with Caspase-3 (r =-0.882,P ＜ 0.05),and positively correlated with Survivin (r =0.889,P ＜ 0.05).Survivin and Caspase-3 were also negatively correlated (r=-0.923,P＜0.05).Conclusion Abnormal expressions of TGF β1,Survivin and Caspase-3 were involved in the formation of intrahepatic bile duct stones associated with bile duct strictures.
ABSTRACT
Objective To investigate the treatment effect of minimally invasive excision in intrahepatic bile duct stones. Methods Ac-cording to different treatment methods, 280 patients with intrahepatic bile duct stones were divided into the treatment group (180 cases) and the control group(100 cases). The control group were given open hepatic lobectomy while the treatment group were given minimally invasive treatment of hepatic lobectomy by laparoscopy. Results All patients had successfully completed surgery and the stones were removed. Compared the operation time,intraoperative blood loss,and blood transfusion of the two groups,and there were no statistically significance (P>0. 05). The postoperative hospitalization,time of drainage tube remove, time of analgestic drug use in treatment group were obviously lower than those in control group,which had statistically significance (P<0. 05). The common postoperative complications of the two groups were bile leakage,wound infection,pleural effusion and subphrenic abscess,et al. The complication rate of treatment group was 2. 2%, while it was 10. 1% in the control group, which had significant difference (P<0. 05). All the patients were followed-up for 6 months, and there was no death in patients. Conclusion Intrahepatic bile duct stones in progress could be treated by hepatic resection surgery. Laparoscopic techniques could accelerate the recovery of patients and reduce the complication rate,and it would become a new treatment option.
ABSTRACT
Objective To explore the value of anatomical liver resection in the treatment of bilateral intrahepatic biliary lithiasis. Methods We collected the clinical data of 32 patients with bilateral intrahepatic biliary lithiasis who received anatomical liver resection and 25 patients who recevied non-anatomical liver resection from May 2010 to May 2012 in our hospital and Sun Yat-sen Memorial Hospital. We comapred the therapeutic efficacy of these two operative modalities in the diagnosis and treatment of bilateral intrahepatic biliary lithiasis. Results The intraoperative blood loss was 436 ±48.162 mL in patients who received anatomical liver resection, and was significantly less than that in the control group (763 ± 37.645ml) ( 0.05 ), but there 1 patients died of liver failure in the control group. Conclusions Anatomical liver resection is a favorable method to completely remove the lesions under the premise of retaining the residual liver function as much as possible. The rate of remnant biliary lithiasis and recurrence is lower and the recovery is quicker in these patients after anatomical liver resection. Thus, anatomical liver resection is worthy of promotion.
