Sixteen cases unresectable carcinoma of the head of the pancreas complicated with jaundice were treated by one stage cholecysto-jejunal and gastro-jejunal loop double anastomosis, the same result of jaundice drainage and prevention of bile reflux were obtained when compared with simple cholecysto-jejunal loop anastomosis, on the other hand, the obstructive symptoms resulting from postoperative cancerous comppression of duodenum and pylorus were avoided as well. The operation is simple with less physiologic disturbance and the patient can lead better postoperative live.
This experimental study was aimed at observing the influence of bile salt and lactulose on intestinal mucosa of obstructive jaundiced rat. Twenty adult Wistar rate were divided into four groups (five rats for each group): sham operation, common bile duct ligation (CBDL), CBDL plus sodium deoxycholate feeding and CBDL plus lactulose feeding. The results showed that the intestinal mucosa of rats with obstructive jaundice took on marked edema, markedly decreased activities of adenosine triphosphatase, alkaline phosphatase and succinic dehydrogenase and intensified acid phosphatase activity. However, the intestinal mucosa of the rats, treated with bile salt or lactulose as compared with that of the obstructive jaundiced rats showed both pathological and histochemical improvement.
Platelet aggregation test (PAgT), platelet adhesion test (PAdT), thromboplastic activity of factor Ⅷ (FⅧ∶c), antithrombin Ⅲ activity (AT-Ⅲ∶a), antithrombin Ⅲ antigen (AT-Ⅲ∶Ag), von willebrand factor (vWF) and fibrinogen (Fg) were measured in 33 patients with biliary tract diseases and 24 normal individuals. The results showed that there was no significant difference in PAgT, PAdT, AT-Ⅲ∶a and AT-Ⅲ∶Ag between the two groups (Ｐ＞0.05). Fg increased more significantly in biliary tract disease than in the controls (Ｐ＜0.01). FⅧ∶c increased more significantly in patients with obstructive jaundice than in that of nonjaundiced and the controls (Ｐ＜0.01). The levels of vWF increased higher and higher in the sequence of patients with no jaundice, obstructive jaundice due to benign diseases and obstructive jaundice due to malignancy(Ｐ＜0.01). In conclusion, Fg, FⅧ∶c and vWF increased in patients with biliary tract disease.
【Abstract】Objective To explore the relation between the expression of telomerase and DNA ploidy with biliarypancreatic system cancer, so as to find a better way to diagnose and distinguish jaundice between malignance and benign disease.Methods Endoscopic retrograde cholangiopancreatography (ERCP) were performed before operation in patients with obstructive jaundice. The bile and pancreatice juice were collected before ERCP. Biopsy specimens from part of patients were obtained during ERCP. All cancer specimens were possessed once again during operation and were assessed by the activity of telomerase and DNA ploidy. Results ① Telomerase positive rate 〔87.50%(56/64)〕 of tissue specimens in malignant obstructive jaundice were higher than that in benign obstructive jaundice 〔3.33%(2/60)〕，P=0.000. ② Telomerase positive rate〔71.88%(46/64)〕of Bile and pancreatice juice in malignant obstructive jaundice were higher than that in benign obstructive jaundice 〔3.33%(2/60)〕， P=0.000, tissue specimens obtained by endoscopy with malignant obstructive jaundice had detectable telomerase activity, positive rate was 83.33%（20/24）. ③ The rate of DNA heteroploid with malignant obstructive jaundice was 62.50%（40/64）, that of diploid can be seen in all patients with benign obstructive jaundice, the difference was statistically significant (P=0.000). ④ The rate of telomerase positive and DNA heteroploid in high differentiation tumor were significantly lower than in middlelow differentiation tumor （P=0.028，P=0.001）.Conclusion Applying the duodenoscope we collected the bile and pancreatic fluid before operation and obtain biopsy specimens whose telomerase activity and DNA ploid were detected. This is simple, safe, quick method which can identify the malignant and benign obstructive jaundice.
ObjectiveTo study the diagnostic value of imaging examinations and their accuracy in evaluating the malignant obstructive jaundice and their resectability. MethodsThe clinical data of 674 malignant obstructive jaundice within 10 years were collected and analyzed.ResultsFor BUS, CT, PTC, ERCP and MRCP, the preoperative accuracy in malignant obstructive jaundice were 74.0%, 86.5%, 88.4%, 92.9% and 94.0%, while the ratio of actual removals in those who had been assessed removable preoperatively were 63.4%, 68.5%, 86.8%, 87.3% and 93.9%, respectively. Conclusion MRCP， PTC, CT and ERCP are better than BUS in the diagnosis of malignant obstructive jaundice (P＜0.05 vs. P＜0.01), while MRCP，ERCP and PTC are much better than BUS and CT in evaluating resectability (P＜0.01). Combination of two or more imaging examinations can improve the accuracy of preoperative diagnosis and assessing resectability.

ObjectiveTo evaluate the role of N-methyl-D-aspartate (NMDA) receptor in central nervous system (CNS) injury of obstructive jaundice. MethodThe related literatures about NMDA receptor and the CNS injury caused by hyperbilirubinemia were retrieved and reviewed. ResultsThe CNS injury of obstructive jaundice was related to overactivation of NMDA receptor, which finally resulted in degeneration and necrosis of nerve cells. The NMDA receptor antagonist MK-801 could relieve the CNS injury of obstructive jaundice. ConclusionsNMDA receptor plays an important role in the CNS injury caused by hyperbilirubinemia, and the blocker of NMDA receptor has protective effects in this process. However, there is no report of MK-801 in clinical application when hyperbilirubinemia happened.
ObjectiveTo explore the value of Aquaporin-3 (AQP-3) on the detection of early renal function damage by investigating the expressions of renal AQP-3 mRNA and protein of rats with obstructive jaundice (OJ). MethodsForty mature male Wistar rats were divided into two groups randomly: experimental group (n=20) in which the model of OJ rats was established, and control group (n=20, sham operation group). The levels of serum total bilirubin (TBIL), direct bilirubin (DBIL), creatinine (Cr)， and blood urea nitrogen (BUN) were detected by fullautomatic biochemical analyzer on 7 d and 14 d after operation. The expressions of renal AQP-3 mRNA and protein of rats were detected by RT-PCR and Western blotting, respectively. ResultsThe levels of serum TBIL and DBIL were significantly higher on 14 d than those on 7 d after operation in experimental group (P=0.000), which were significantly higher than those at corresponding time point in control group (P=0.000), while the difference within control group was not significant (P=0.154). Thus, the OJ models of rats were established successfully. The difference of serum Cr levels of rats between inter-and intragroup were not significant (Pgt;0.05). Serum BUN level on 14 d after operation in experimental group was significantly higher than those on 7 d after operation in experimental group and on 14 d after operation in control group (P=0.001), although serum Cr levels were not different between 7 d and 14 d after operation in control group (P=0.288). The expressions of AQP-3 protein of rats on 7 d and 14 d after operation in experimental group were significantly lower than those at corresponding time point in control group (P=0.033, P=0.000), meanwhile on 14 d after operation in experimental group was significantly lower than those on 7 d after operation in experimental group (P=0.000). The expressions of AQP-3 mRNA of rats on 7 d and 14 d after operation in experimental group were significantly higher than those at corresponding time point in control group (P=0.000), but the difference at different time point in two groups was not significant (P=0.139, P=0.059). ConclusionsThe changes of renal AQP-3 protein and mRNA expressions are prior to the changes of serum Cr and BUN levels of rats suffered from OJ complicated renal function damage, which are promised to improve the early diagnosis rate of renal function damage in rats with OJ.
ObjectiveTo investigate the efficacy of different methods of reducing jaundice in patients with low malignant obstructive jaundice undergoing pancreaticoduodenectomy. Methods A retrospective analysis was performed on the clinicopathological data of patients admitted to the Department of Hepatobiliary Surgery of The Affiliated Hospital of Guizhou Medical University from January 2014 to June 2020 who were considered to have low malignant obstructive jaundice before operation and confirmed by postoperative pathological examination as pancreatic cancer, ampulla cancer, duodenal cancer or carcinoma of the lower segment of the common bile duct. Patients were devide into percutaneous transhepatic cholangial drainage (PTCD) group and endoscopic retrograde biliary drainage (ERBD) group according to preoperative biliary drainage (PBD) methods. In order to reduce selection bias, SPSS propensity matching module was used for propensity score matching analysis. The age, basic diseases (hypertension, diabetes), biochemical indexes, time of reduction of jaundice, total hospitalization time, and postoperative complications of PBD and pancreaticoduodenectomy were compared between the 2 groups. Then, the patients were divided into pancreatic cancer group and non-pancreatic cancer group (including ampulla cancer, duodenal carcinoma and lower common bile duct carcinoma) by tumor type, and compared the effect of two groups of patients receiving different PBD methods. Results A total of 84 patients, 43 males and 41 females, were included in this study, 58 (69.0%) patients with PTCD and 26 (31.0%) patients with ERBD. After PBD the serum total bilirubin, direct bilirubin, γ-glutamyl transferase, and alkaline phosphatase of the PTCD and the ERBD groups patients were lower than before PBD, the differences were statistically significant (P<0.05). Alanine aminotransferase did not change significantly before and after PBD with PTCD (P>0.05), but decreased significantly after PBD with ERBD (P<0.05). Aspartate aminotransferase did not change significantly before and after PBD with ERBD (P>0.05), but decreased significantly after PBD with PTCD(P<0.05). The PBD time and total hospitalization time of the ERBD group were shorter than those of the PTCD group, the differences were statistically significant (P<0.05). The incidences of PBD related complications (cholangitis and pancreatitis) in the ERBD group were higher than those the PTCD group, and the incidence of bleeding in the ERBD group was lower than that the PTCD group, but the differences were not statistically significant (P>0.05). In the patients with pancreatic cancer group, the PBD time by ERBD was shorter than that of the receiving PTCD, the difference was statistically significant (P=0.006). In the non-pancreatic cancer group, the total hospitalization time and PBD time of patients receiving ERBD were shorter than those receiving PTCD, and the differences were statistically significant (P<0.05). In all patients, the median survival time of PTCD group (14 months) was shorter than that in ERBD group (18 months), P=0.002; pancreatic cancer group (12 months) was shorter than non-pancreatic cancer group (16 months), P=0.034; in non-pancreatic cancer group, ERBD group (20 months) was longer than PTCD group (15 months), P=0.008. Conclusions ERBD can shorten the waiting time of operation and hospital stay as compared with PTCD, and has a longer median survival time. It can be used as the first choice for PBD in patients with low malignant obstructive jaundice.
