Endoscopic retrograde cholangiopancreatography (ERCP) is currently the first-line minimally invasive diagnosis and treatment of biliary and pancreatic diseases. With the increasing popularity of ERCP, ERCP-related adverse events which include post-ERCP pancreatitis, cholecystitis, cholangitis, bleeding, perforation, etc., have received more and more attention. In response to the controversy and problems in the management of these adverse events, the European Society of Gastrointestinal Endoscopy published the guidelines for ERCP-related adverse events in December 2019. The paper interprets the key points in the guideline to provide references for clinical practice.
Objective To analyze the clinical characteristics associated with hospital infections in patients with common bile duct stones treated by endoscopic retrograde cholangiopancreatography (ERCP) and laparoscopic common bile duct exploration (LCBDE), thereby providing a basis for selecting treatment strategies and formulating hospital infection prevention measures for such patients. Methods Patients with common bile duct stones at Jiangsu Provincial People’s Hospital between January 2020 and July 2023 were retrospectively selected and divided into ERCP and LCBDE groups according to their surgical methods. Basic patient data, length of hospital stay, hospitalization costs, perioperative infection-related indicators, and occurance of hospital infections were compared between groups. Results A total of 402 patients were enrolled, with 242 in the ERCP group and 160 in the LCBDE group. Significant differences were noted in smoking, alcohol consumption, history of lung diseases, history of heart diseases, history of cholecystectomy/biliary surgery, presence of cholecystitis, presence of cholecystolithiasis, number of stones, maximum stone diameter, common bile duct diameter, total hospital stay, and total expenses (P<0.05). Twenty-four hours before surgery, except for the neutrophil count, which was slightly higher in the ERCP group than that in the LCBDE group (P=0.043), the infection-related indicators did not differ significantly between the two groups (P>0.05). Twenty-four hours after surgery, the levels of serum white blood cell, neutrophil, and aspartate aminotransferase in the ERCP group were lower than those in the LCBDE group (P<0.05), and the levels of alkaline phosphatase and gamma-glutamyl transferase in the ERCP group were higher than those in the LCBDE group (P<0.05). A total of 179 bile samples were collected and tested, identifying 137 strains of pathogenic bacteria (78 in the ERCP group and 59 in the LCBDE group). In the ERCP group, 42 strains (53.85%) were Gram-negative bacteria, 34 strains (45.59%) were Gram-positive bacteria, and 2 strains (2.56%) were fungi; in the LCBDE group, 33 strains (55.93%) were Gram-negative bacteria and 26 strains (44.07%) were Gram-positive bacteria. No significant difference was observed in the composition of pathogenic bacteria between the two groups (χ2=1.174, P=0.695). Among the 402 patients, 38 cases of hospital infection occurred postoperatively, with an infection rate of 9.45%. The difference in the infection rate between the ERCP group and the LCBDE group were statistically significant (11.98% vs. 5.63%; χ2=4.550, P=0.033). The main sites of infection were bloodstream, lungs, and abdominal-pelvic cavity. Conclusions The predominant pathogens isolated after both ERCP and LCBDE are Gram-negative bacteria. Compared with LCBDE, ERCP has less impact on inflammatory markers, hospital stay, and costs, but has a higher incidence of hospital infections.
ObjectiveTo discuss the relation between bile duct anastomotic stricture and bile duct injury by endo-scopic observation following liver transplantation and it, s efficacy of endoscopic treatment. Method The clinical data of 24 cases of bile duct anastomotic stricture following liver transplantation diagnosed by cholangiography were analyzed retro-spectively. Results①Twenty-four cases of bile duct anastomotic strictures were included in 3 cases of typeⅠa, 2 cases of typeⅠb, 4 cases of typeⅡ, 1 case of typeⅢa, 5 cases of typeⅢb, and 9 cases of typeⅢc.②The redness of intrahepatic bile duct mucosa, banding erosion, ulcer and fusion of anastomotic stricture mucosa could be seen in typeⅠa andⅢa. The redness of intrahepatic bile duct and anastomotic stricture mucosa could be seen in typeⅡwithout ulcer and fusion. The extensive erosion and ulcer of intrahepatic bile duct and redness of anastomotic stricture mucosa could be seen in typeⅢb. The extensive erosion, ulcer and partial necrosis of intrahepatic bile duct and anastomotic stricture mucosa could be seen in typeⅠb andⅢc.③Seventeen cases were cured by choledochoscopy through T tube, the biliary casts were moved out and the anastomotic strictures were relieved by balloon dilatation and placement of plastic stenting for 2 to 6 months, no recurrence happened. One case of typeⅠb treated by percutaneous transhepatic cholangial drainage(PTCD) and percuta-neous transhepatic cholangioscopy(PTCS) was developed into the stricture of typeⅡduring following-up for 19 months. Two cases of typeⅠa were treated by ERCP, the biliary casts were moved, one of which was cured, another 1 case was developed into the stricture of typeⅡduring following-up for 5 months. Two cases of typeⅡwere treated by ERCP, the biliary casts were moved, balloon dilatation and placement of plastic stent were performed, one of which was cured, another 1 case was recurrent during following-up for 1 months. The strictures were not relieved by multiple plastic stents for 4 to 6 months in 3 patients with recurrence and progress, but which was relieved by full-covered self-expanding removable metal stents for 4 to 7 months, there was no recurrence during following-up. One case of typeⅢb and one case of typeⅢc received the secondary open operation or choledochoscopy and placement of plastic stent for biliary infection and jaundice after the treatment of ERCP were cured. ConclusionsBiliary stricture following liver transplantation accompanies different degree biliary injury. The slightest is typeⅡand typeⅠa, typeⅢa is the second, typeⅢb is more serious, and typeⅠb and typeⅢc are the worst. Choledochoscopy is a better choose for anastomotic strictures. ERCP is not a better choose for anastomotic strictures of typeⅠb, Ⅲb, andⅢc.
Objective To explore and summarize the application of minimally invasive technique to every stage of severe acute pancreatitis (SAP). Methods The treatment of 101 SAP patients admitted to our hospital between January 1995 and December 2008 were retrospectively analyzed. After calculi were removed by endoscopic retrograde cholangiopancreatograpy (ERCP) and endoscopic sphincterotomy (EST), endoscopic nasobiliary drainage (ENBD) were applied, then rhubarb liquid was perfused into gut with a nutrient canal and ultrasound-guided abdominal drainage tube were simultaneously placed at the early stage. Some patients received continuous renal replacement therapy (CRRT) at the same time. Laparoscopic cholecystectomy (LC) was performed at the subacute stage, and choledochoscope was introduced to remove parapancreatic necrotic tissues at the late stage of SAP.Results Of all the 101 cases treated by the method mentioned above, 75 cases received ERCP (or EST) and ENBD, and 31 cases underwent rhubarb liquid perfusion with a nutrient canal. Eight cases underwent continuous renal replacement therapy (CRRT). Forty-eight cases underwent LC and ultrasoundguided abdominal drainage. Thirtysix cases with infected peripancreatic tissue or abscess underwent debridement under choledochoscope 3 to 14 times at the later stage. Five cases died of multiple organ failure (MOF) and acute respiratory distress syndrome (ARDS). The hemobilia ocurred in 2 patients during choledochoscopy and was cured under direct visualization by electric coagulation. Intestinal fistula happened in 3 cases and cured by drainage. Pancreatic pseudocyst was latterly seen in 3 cases and treated by the anastomosis of cyst with jejunum through selective operation. After the hospitalization of 9-132 d (mean 24 d), 96 cases completely recovered. Conclusion Timely application of minimally invasive technique to every stage of SAP can avoid the defects of traditional operations, decrease the injury and interference to the maximum, and raise the cure rate.
ObjectiveTo compare the cost-effectiveness between endoscopic retrograde cholangio-pancreatography (ERCP) treatment and laparotomy treatment for simple common bile duct stone or common bile duct stone combined with gallbladder benign lesions. MethodsA total of 596 patients with common bile stone received ERCP (ERCP group) and 173 received open choledocholithotomy (surgical group) in our hospital between January 2009 and December 2012. Their clinical data were retrospectively analyzed. The curing rate, postoperative complications, hospital stay, preoperational preparation and total cost were compared between the two groups of patients. Meanwhile, for common bile stone combined with gallbladder benign lesion, 29 patients received ERCP combined with laparoscopic cholecystectomy (LC) (ERCP+LC group), 38 received pure laparoscopy treatment (laparoscopy group) and 129 received open choledocholithotomy combined with cholecystectomy (surgery group). ResultsFor simple common bile stone patients, no significant difference was found in cure rate and post-operative complication between endoscopic and surgical treatment groups (P>0.05). However, total hospitalization expenses[(13.1±6.3) thousand yuan, (20.6±7.5) thousand yuan)], hospital stay[(8.91±4.95), (12.14±5.15) days] and preoperative preparation time[(3.77±3.09), (5.13±3.99) days] were significantly different between the two groups (P<0.05). For patients with common bile stone combined with gallbladder benign lesion, no significant discrepancy was detected among the three groups in curing rate and post-operative complications (P>0.05). Significant differences were detected between ERCP+LC group and surgical group in terms of total hospitalization expense[(18.9±4.6) thousand yuan, (23.2±8.9) thousand yuan] hospital stay[(9.00±3.74), (12.47±4.50) days] and preoperative preparation time[(3.24±1.83), (5.15±2.98) days]. No significant difference was found in total hospitalization expense and hospital stay, while significant difference was detected in preoperative preparation time between ERCP+LC group and simple LC group. ConclusionFor patients with simple common bile stone, ERCP is equivalent to surgery in the curing rate, and has more advantages such as less cost, shorter length of hospital stay, and lower preoperative preparation time. For the treatment of common bile duct stone with gallbladder benign disease, ERCP combined with LC also has more advantages than traditional surgery.

Objective To explore the value of endoscopic retrograde cholangiopancreatograph (ERCP) and extracorporeal shock wave lithotripsy (ESWL) in the treatment of pancreatic duct stones. Methods A retrospective collection of 28 patients with chronic pancreatitis and pancreatic duct stones admitted to the Department of Gastroenterology from January 2010 to August 2021 was performed. According to the treatment of patients, they were divided into ERCP direct stone extraction group and ESWL combined ERCP stone extraction group. We compared the treatment effects of the two groups of patients, including the success rate of stone extraction, postoperative complications of ERCP, postoperative symptom improvement, and so on. Results Among the 28 patients, 19 cases underwent ERCP direct stone extraction, and 9 cases underwent ESWL combined with ERCP stone extraction. In the ERCP direct stone extraction group, 7 cases (36.84%) were completely extracted, 1 case was partially extracted (5.26%), and 11 cases (57.89%) failed to extract and only placed stents and drained; 5 cases (26.32%) had elevated white blood cells at 6 hours postoperatively, C-reactive protein increased in 4 cases (21.05%), 3 cases (15.79%) were diagnosed as ERCP-related pancreatitis, and 2 cases (10.53%) were diagnosed as hyperamylaseemia. The abdominal pain symptoms were completely relieved in 14 cases (73.68%) during a follow-up period of 3 to 6 months. The body mass of 17 cases (89.47%) increased in the 6 months after stone extraction. ESWL combined with ERCP had complete stone extraction in 5 cases (55.56%), partial stone extraction in 3 cases (33.33%), and failure in stone extraction and only stent drainage in 1 case (11.11%). One case (11.11%) had elevated white blood cells at 6 hours postoperatively, and 1 case (11.11%) had elevated C-reactive protein . One case (11.11%) was diagnosed with ERCP-related pancreatitis. One case (11.11%) got abdominal pain and transient hematuria during ESWL, which resolved spontaneously 3 days later. After 3 to 6 months of follow-up, 9 patients (100%) had complete relief of abdominal pain symptoms, and the body mass of 9 patients (100%) increased in the 6 months after stone extraction. The stone clearance rate of the ESWL combined with ERCP stone extraction group was higher than that of the ERCP direct stone extraction group (P=0.033), but there was no statistically significant difference between the two groups in terms of ERCP-related complications, relief of abdominal pain, and weight gain (P>0.05). Conclusion ESWL combined with ERCP in the treatment of chronic pancreatitis complicated with pancreatic duct stone extraction is more effective than ERCP direct stone extraction.
Objective To evaluate the efficacy of direct vision guided lithotripsy with SpyGlass DS in the treatment of pancreatic duct obstruction caused by chronic calcified pancreatitis and pancreatic duct stones. Methods The clinical data of 9 patients with chronic calcified pancreatitis and pancreatic duct stone who underwent direct-vision guided pancreatic duct stone lithotripsy with SpyGlass DS from July 2017 to September 2017 in the Department of Gastroenterology of Jilin People’s Hospital were retrospectively analyzed, then assessment of technical success rate, clinical success rate, and incidence of adverse event were performed. Results A total of 13 times of intervention were performed in 9 patients, the overall technical success rate of SpyGlass DS direct vision lithotripsy and drainage was 88.9% (8/9). Three of the 9 patients (30.3%) had adverse reactions, including self-limiting bleeding after sphincterotomy (n=1), post-encoscopic retrograde cholangio-pancreatography pancreatitis (n=2), and mild abdominal pain (n=2). Nine patients were followed-up for 3－50 months (median of 21 months), 8 patients (88.89%) reported improvement in abdominal pain, and the mean visual analogue scale score decreased from 6.22±1.47 to 2.78±1.23, P<0.01. Eight patients (88.9%) patients achieved clinical success. Conclusion The SpyGlass DS direct vision-guided lithotripsy is safe and effective for patients with pancreatic duct stones.
