Biliary Microbial Structure of Gallstone Patients With a History of Endoscopic Sphincterotomy Surgery.

ABSTRACT: The biliary microbiota is related to the pathogenesis of human bile duct stones. However, the extent to which a history of invasive endoscopic sphincterotomy (EST) affects the biliary bacterial community remains largely unknown. We collected bile samples from the common bile duct of 100 choledocholithiasis patients. We performed 16S rRNA sequencing to investigate and compare the biliary microbial community. The patients without antibiotic treatment (AT) were grouped into three clusters based on their biliary microbial compositions. The patients with a history of EST were significantly enriched in one cluster mainly consisting of gastrointestinal bacteria compared with the other two clusters consisting of oral and environmental bacteria. The ?-diversities of patients with and without EST were also significantly different, whereas the ?-diversities were comparable. The only significantly enriched bacterial genus associated with a history of EST was Pyramidobacter, while eight other genera were significantly decreased. For patients with AT, seven of these genera maintained their association with EST, including Pyramidobacter. However, after AT, the difference in ?-diversities was diminished. EST induced a marked shift in the biliary microbial composition. A cluster of biliary bacteria was associated with a history of EST, and Pyramidobacter was specific to EST.

Project description:Post-endoscopic sphincterotomy bleeding is a common complication of biliary sphincterotomy, and the incidence varies from 1% to 48%. It can be challenging to localize the bleeder or to administer various interventions through a side-viewing endoscope. This study aimed to evaluate the risk factors of post-endoscopic sphincterotomy bleeding and the outcome of endoscopic intervention therapies. We retrospectively reviewed the records of 513 patients who underwent biliary sphincterotomy in Mackay Memorial Hospital between 2011 and 2016. The blood biochemistry, comorbidities, indication for sphincterotomy, severity of bleeding, endoscopic features of bleeder, and type of endoscopic therapy were analyzed. Post-endoscopic sphincterotomy bleeding occurred in 65 (12.6%) patients. Forty-five patients had immediate bleeding and 20 patients had delayed bleeding. The multivariate analysis of risk factors associated with post-endoscopic sphincterotomy bleeding were liver cirrhosis (P = 0.029), end-stage renal disease (P = 0.038), previous antiplatelet drug use (P<0.001), and duodenal ulcer (P = 0.023). The complications of pancreatitis and cholangitis were higher in the bleeding group, with statistical significance. Delayed bleeding occurred within 1 to 7 days (mean, 2.5 days), and 60% (12/20) of the patients received endoscopic evaluation. In the delayed bleeding group, the successful hemostasis rate was 71.4% (5/7), and 65% (13/20) of the patients had ceased bleeding without endoscopic hemostasis therapy. Comparison of different therapeutic modalities showed that cholangitis was higher in patients who received epinephrine spray (P = 0.042) and pancreatitis was higher in patients who received epinephrine injection and electrocoagulation (P = 0.041 and P = 0.039 respectively). Clinically, post-endoscopic sphincterotomy bleeding and further endoscopic hemostasis therapy increase the complication rate of pancreatitis and cholangitis. Realizing the effectiveness of each therapeutic modalities and appropriate management of different levels bleeding are important.

Project description:BackgroundEndoscopic sphincterotomy (ES) is the standard treatment for common bile duct stones. The reported findings regarding complications, such as biliary pancreatitis and cholangitis, differ between cholecystectomy after ES. The purpose of this study is to compare cholecystectomy outcomes after endoscopic treatment of common bile duct stones whether or not the incidence of recurrent pancreatitis and cholangitis is reduced, especially in high-risk patients.MethodsWe analyzed 8 studies, including 7 randomized controlled trials retrieved from the PubMed (1990-2019), Embase (1990-2019), and Cochrane (1990-2019) databases for trials comparing the two strategies for treatment of gallstones after ES. A related study on gallbladder removal after ES was acquired, followed by analysis of each group using RevMan. Risk ratios (RRs) were calculated for categorical variables and differences in means were calculated for continuous variables.ResultsWe retrieved a total of 8 studies, including seven randomized controlled trials and one retrospective study. A total of 12,717 patients were included in the study (4922 in the early cholecystectomy group and 7795 in the gallbladder in situ group). During the follow-up period, 41 patients had pancreatitis after ES in the cholecystectomy group and 177 patients in the wait-and-see group. The incidence of pancreatitis in the cholecystectomy group was significantly reduced (RR, 0.38; 95% CI, 0.27-0.53; P < 0.00001; I2 = 0%). The incidence of cholangitis and jaundice in the cholecystectomy group was also less than the preserved gallbladder group (RR, 0.31; 95% CI, 0.26-0.38; P < 0.00001; I2 = 0%). There was no significant difference in mortality between the two groups (RR, 0.73; 95% CI, 0.52-1.02; P = 0.07; I2 = 14%). There was a significant difference in cholecystitis and biliary colic (RR, 0.28; 95% CI, 0.24-0.32; P < 0.00001; I2 = 17%).ConclusionEarly cholecystectomy after removal of common bile duct stones can effectively reduce biliary complications. This is still true for high-risk patients and has no significant effect on the mortality of patients. Laparoscopic cholecystectomy is recommended after ES.
