METHODS Data from 153 consecutive patients who underwent preoperative endoscopic biliary drainage prior to PD between January 2009 and July 2016 were analyzed. We compared the clinical data, procedure-related complications of endoscopic biliary drainage (EBD) and postoperative complications of PD between the ENBD and ERBD groups. Univariate and multivariate analyses with odds ratios (ORs) and 95% confidence intervals (95% CIs) were used to identify the risk factors for deep abdominal infection after PD. RESULTS One hundred and two (66.7%) patients underwent ENBD, and 51 (33.3%) patients underwent ERBD. Endoscopic sphincterotomy was less frequently performed in the ENBD group than in the ERBD group (P = 0.039); the EBD duration in the ENBD group was shorter than that in the ERBD group (P = 0.036). After EBD, the levels of total bilirubin (TB) and alanine aminotransferase (ALT) were obviously decreased in both groups, and the decreases of TB and ALT in the ERBD group were greater than those in the ENBD group (P = 0.004 and P = 0.000, respectively). However, the rate of EBD procedure-related cholangitis was significantly higher in the ERBD group than in the ENBD group (P = 0.007). The postoperative complications of PD as graded by the Clavien-Dindo classification system were not significantly different between the two groups (P = 0.864). However, the incidence of deep abdominal infection after PD was significantly lower in the ENBD group than in the ERBD group (P = 0.019). Male gender (OR = 3.92; 95% CI: 1.63-9.47; P = 0.002), soft pancreas texture (OR = 3.60; 95% CI: 1.37-9.49; P = 0.009), length of biliary stricture (= 1.5 cm) (OR = 5.20; 95% CI: 2.23-12.16; P = 0.000) and ERBD method (OR = 4.08; 95% CI: 1.69-9.87; P = 0.002) were independent risk factors for deep abdominal infection after PD. CONCLUSION ENBD is an optimal method for patients with malignant distal biliary obstruction prior to PD. ERBD is superior to ENBD in terms of patient tolerance and the effect of biliary drainage but is associated with an increased risk of EBD procedure-related cholangitis and deep abdominal infection after PD.

Procedure-related adverse events, stent/catheter dysfunction (occlusion or migration of PS/NBC, development of cholangitis, or other conditions that required repeat endoscopic biliary intervention), and jaundice resolution (bilirubin level < 3.0 mg/dL) were evaluated. Cumulative incidence of jaundice resolution and dysfunction of PS/NBC were estimated using competing risk analysis. Patient characteristics and preoperative biliary drainage were also evaluated for association with the time to jaundice resolution and PS/NBC dysfunction using competing risk regression analysis.RESULTS: In total, 419 patients were included in the study (PS, 253 and NBC, 166). Primary cancers included pancreatic cancer in 194 patients (46%), bile duct cancer in 172 (41%), gallbladder cancer in three (1%), and ampullary cancer in 50 (12%). The median serum total bilirubin was 7.8 mg/dL and 324 patients (77%) had ≥ 3.0 mg/dL. During the median time to surgery of 29 d [interquartile range (IQR), 30-39 d]. PS/NBC dysfunction rate was 35% for PS and 18% for NBC [Subdistribution hazard ratio (SHR) = 4.76; 95%CI: 2.44-10.0, P < 0.001]; the pig-tailed tip was a risk factor for PS dysfunction. Jaundice resolution was achieved in 85% of patients and did not depend on the drainage method (PS or NBC).CONCLUSION: PS has insufficient patency for preoperative biliary drainage. Given the drawbacks of external drainage via NBC, an alternative method of internal drainage should be explored.展开更多

According to different drainage schemes,patients were divided into the endoscopic nasobiliary cutting group (n = 26) and the endoscopic retrogradebiliary drainage (ERBD) group (n = 29). The postoperative liver function indexes, incidence of postoperativecomplications, median patency period of stents, and median survival time of patients were comparedbetween the two groups.Results Liver function indexes (total bilirubin, direct bilirubin, alanine aminotransferase, aspartateaminotransferase, alkaline phosphatase, gamma-glutamyl transpeptidase) were significantly decreased in55 patients a week postoperaticely (P < 0.05), and decreases in liver function indexes in the endoscopicnasobiliary cutting group were more significant than those in the ERBD group (P < 0.05). The incidenceof biliary tract infection in the endoscopic nasobiliary cutting group was significantly lower than that in theERBD group (15.40% vs. 41.4%, P < 0.05). In the endoscopic nasobiliary cutting subgroups, there were 1and 3 cases of biliary tract infection in the gastric antrum cutting group (n = 21) and duodenal papilla cuttinggroup (n = 5), respectively, and 0 cases and 2 cases of displacement, respectively;there was a statisticallysignificant difference in terms of complications between the two subgroups (P < 0.05). The median patencyperiod (190 days) and median survival time (230 days) in the nasobiliary duct cutting group were higherthan those (169 days and 202 days) in the ERBD group, but there was no significant difference (P > 0.05).Conclusion The nasobiliary duct was cut by using endoscopic scissors in Stage II after the bile was fullydrained through the nasobiliary duct. The residual segment could still support the bile duct and drain bile.The reduction of jaundice and the recovery of liver enzymes were significant, and the incidence of biliarytract infection was low. Cutting off the nasobiliary duct at the duodenal papilla results in a higher incidenceof biliary tract infection, and the residual segment of the nasobiliary duct is more likely to be displaced.Endoscopic nasobiliary-cutting drainage is an effective, simple, and safe method to reduce jaundice in thepalliative treatment of HC.展开更多
