ObjectiveTo study the effectiveness of liver function, hepatic energy metabolism, regeneration, and apoptosis on the obstructive jaundice rat after partial hepatectomy (PH) combined with internal biliary drainage under the condition of conspicuous bilirubinemia. MethodsOne hundred and twenty male SD rats were used in research, six of whom were divided into sham operation (SO) group. Twenty rats underwent bridge operation between common bile duct and duodenum after 70% PH (70%PH group), and 6 rats out of the 94 rats who underwent common bile duct ligation (CBDL) for 5 d were randomly selected as CBDL group, and the residual rats were done the second operations after 5 d and were divided into three groups: bile duct obstruction combined with reperfusion of bile flow group （BDO-RBF group， n=20), 42% PH with BDO-RBF group (n=20), and 70%PH with BDO-RBF group (n=25). Levels of TB, ALT, ALB, and ALP in serum; HGF, bcl-2 mRNA and protein； ATP, ADP, and AMP; hepatocyte proliferation/apoptosis index in hepatic tissues were dynamically observed after operation (24 h, 72 h, and 7 d), respectively. The liver function and hepatocyte energy metabolism were only detected in the SO group. ResultsRats without obstructive jaundice would have an excellent liver regeneration after 70% PH, while the liver function and hepatocyte energy metabolism could recover rapidly. The liver function, hepatocyte energy metabolism, HGF and bcl-2 mRNA and protein of liver tissue and the hepatocyte proliferation/apoptosis index in partial (42% or 70%) hepatectomy combined with internal biliary drainage in obstructive jaundice group were significantly influenced while recovered rapidly (Plt;0.05). ConclusionsUnder the condition of conspicuous bilirubinemia, the influences of hepatectomy combined with internal biliary drainage on hepatocyte energy metabolism, liver function, hepatocyte regeneration and apoptosis are severer than that of normal rats who underwent 70% hepatectomy, while also make the rats recover rapidly in hyperbilirubinemia groups. The database suggest that it is not necessary to do preoperative external biliary drainage before performing liver resection.
Objective To investigate the cause, treatment, and prognosis of the postpancreaticoduodenectomy hemorrhage (PPH) . Method A total of 779 patients who underwent pancreaticoduodenectomy at Fudan University Shanghai Cancer Center between January 2015 and December 2016 were enrolled, and the data of them were retrospectively analyzed. Results Sixteen patients (PPH group) suffered from PPH and 763 patients didn’t suffered from PPH (non-PPH group) of 779 patients. There was no significant difference in the age, gender, type of disease, operative time, blood loss, and ratio of blood transfusion between the 2 groups (P>0.05), but the incidences of pancreatic fistula and delayed gastric emptying, postoperative drainage time, hospital stay, and mortality were all higher or longer in PPH group compared with non-PPH group (P<0.001). Of the 16 PPH patients, early haemorrhage occurred in 3 patients (including 2 patients with gastrointestinal haemorrhage and 1 patient with intra-abdominal haemorrhage) and delayed haemorrhage occurred in 13 patients (including 6 patients with gastrointestinal haemorrhage and 7 patients with intra-abdominal haemorrhage). All the 3 patients with early haemorrhage were cured by surgery. Of the 13 patients with delayed haemorrhage, 5 patients were cured by radiological intervention, 2 patients were cured by endoscopic hemostasis, and 3 patients were cured by conservative treatment, but 3 patients with sentinel bleeding died after interventional embolization+surgery. Conclusions The mortality of PPH is high. Surgery is optimal to early haemorrhage and radiological intervention is optimal to delayed haemorrhage, including embolization or covered stent implantation. The sentinel bleeding should be given great attention.
ObjectiveTo investigate the prognostic impact of tumor location in gallbladder carcinoma in different sites and evaluate the effect of surgical operation on the median survival time of patients.MethodsFrom 2012 to 2016, 382 patients with gallbladder cancer in the Eastern Hepatobiliary Surgery Hospital were divided into 163 cases of gallbladder duct cancer and 219 cases of gallbladder bottom and body cancer. They were received radical resection, extended radical resection and palliative resection.ResultsThe mean survival time was (19.57+15.63) months in the bottom and body cancer group, (14.62+11.12) months in the cystic duct carcinoma group, and the survival time was significantly different between the two groups (P<0.05). After radical surgery, the mean survival time in the cystic duct carcinoma group and the bottom and body cancer group were (23.82±12.47) months and (30.63±17.81) months, respectively, there was no significant difference between the two groups (P>0.05). The multivariate analysis indicated that tumor location, surgical radical therapy, clinical stage, pathological grade, and pathological classification were all independent risk factors influencing the prognosis of patients (P<0.05). There was no significant difference in median survival time between the two groups (P>0.05).ConclusionsThe prognosis of patients with cystic duct gallbladder carcinoma is worse than that of patients with the bottom and body cancer of the gallbladder, but the prognosis of the two groups after radical resection is similar. The prognosis of patients with extended radical operation according to the condition is similar to that of routine radical operation. There are some differences in clinical stage, pathological grade and pathological classification between the two groups of gallbladder cancer patients. In addition, the great differences exist in the surgical methods, especially in extended radical operation. Therefore, the treatment of gallbladder cancer in these two locations should be treated differently.
