Endoscopic ultrasonography (EUS) has progressed beyond diagnostic imaging to include EUS-guided tissue acquisition and EUS-directed therapies. This review provides an update on EUS-guided drainage and anastomotic procedures, and other therapeutic procedures. Today, EUS-guided drainage of symptomatic walled-off pancreatic fluid collections is the norm, with endoscopic necrosectomy as an adjunct. For high-risk surgical patients unsuitable for cholecystectomy, EUS-guided gallbladder drainage of acute cholecystitis is an option. Additionally, EUS-guided drainage of obstructed biliary and pancreatic ductal system can be performed as salvage procedures after unsuccessful endoscopic retrograde cholangiopancreatography (ERCP). Bariatric procedures such as Roux-en-Y gastric bypass alter the gastric anatomy, hindering access to the major papilla. This can be overcome by creating a conduit through the excluded stomach using EUS-directed transgastric ERCP. Gastric outlet obstruction and afferent loop syndrome can be treated using EUS-guided gastrojejunostomy. These therapeutic interventions are a major advancement in the field of interventional EUS, achieving significant clinical impact.

Jaundice in older children can occur when any obstruction is found within the bile ducts, either from bile stones, parasites, choledochal cysts and rarely, secondary to tumors. We present a previously well, 10-year-old Filipino boy with three-week history of progressive jaundice and tea-colored urine, and was initially assessed to have biliary ascariasis. Ultrasound showed a heterogeneous focus spanning the gallbladder neck and confirmed on endoscopic retrograde cholangiopancreatography as an exophytic mass at the ampulla of Vater. Tumor biopsy and immunohistochemical staining confirmed the diagnosis of Embryonal Rhabdomyosarcoma of the Bile Ducts. Chemotherapy was initiated to reduce the size of the tumor before any surgical intervention could be attempted. Despite chemotherapy, the tumor progressively grew. He acquired a respiratory infection which led to sepsis and his eventual demise. The disease should be considered in the differential diagnosis of a child with obstructive jaundice after exclusion of other more common causes.

Objective: To investigate the efficacy and safety of endoscopic retrograde cholangiopancreatography (ERCP) in the diagnosis and treatment of biliary and pancreatic diseases in children. Methods: The clinical data of 127 children who were treated with ERCP in the First Affiliated Hospital of Nanchang University from January 2007 to July 2021 were analyzed. According to the diseases they suffered from, the children were divided into biliary group and pancreatic group. The operation times, technical success rate, diagnosis, interventions and post-ERCP complications between the groups were compared by t-test or χ² test. The risk factors of post-ERCP pancreatitis (PEP) were analyzed by multivariate Logistic regression. Results: A total of 127 children, including 54 males and 73 females, with a median age of 14 years at first ERCP, were included in this study. ERCP was performed in 181 cases, with a success rate of 98.3% (178/181). In pre-ERCP imaging examination, the positive diagnostic rates of ultrasound, CT and magnetic resonance cholangiopancreatography (MRCP) for biliary and pancreatic diseases were 54.1% (53/98), 56.1% (37/66) and 79.3% (88/111), respectively. MRCP had the highest positive diagnostic rate, and the difference among the three measures was statistically significant (χ²=17.33, P<0.001). The most common indications for ERCP in biliary and pancreatic diseases were choledocholithiasis (77.0%, 107/139) and congenital structural abnormalities of the pancreas (31.0%, 13/42), respectively. After ERCP, the abdominal pain was dramatically relieved and the liver function was significantly improved (all P<0.001). The blood amylase level of the children with pancreatic diseases was significantly lower than that before ERCP (t=7.73, P<0.001). The overall incidence of post-ERCP complications was 12.2% (22/181), of which post-ERCP pancreatitis (PEP) was the most common (7.2%, 13/181). The incidence of PEP was significantly higher in the pancreatic group than in the biliary group (16.7% (7/42) vs. 4.3% (6/139),χ²=7.38, P=0.007). Multivariate Logistic regression analysis showed that young age was the independent risk factor of PEP (OR=0.80, 95%CI 0.67-0.96). Conclusions: MRCP is the first choice for pre-ERCP imaging examination of biliary and pancreatic diseases in children. ERCP can be safely and effectively used in the diagnosis and treatment of biliary and pancreatic diseases in children, with a high success rate and obvious alleviation of symptoms.

OBJECTIVE: To distinguish clinical features, safety and efficiency of endoscopic retrograde cholangiopancreatography (ERCP) in patients after bilioenteric anstomosis based on retrospectively analyzed clinical data and endoscopy procedures. METHODS: Data extracted from patients after bilioenteric anstomosis due to biliary disease treated with ERCP from January 2005 to December 2021 in the Department of Gastroenterology, Peking University Third Hospital were retrospectively analyzed. Clinical data and endoscopic pictures were reevaluated and analyzed. The patients were divided into three groups, including the patients with choledochoduodenostomy (CDD), Roux-en-Y hepaticojejunostomy (RYHJ) and Whipple. Differences between ERCP success and failure were conducted. RESULTS: In the study, 89 cases with 132 ERCP procedures were involved, 9-80 years old, median 57 years old, containing 4 CDD, 30 RYHJ, 54 Whipple and 1 bile duct ileocecal anastomosis patients; The time between ERCP and surgery were 30 (1-40), 2.75 (0.5-14), 2 (0.3-19), and 10 years, respectively; The time between surgery and symptom were 240 (3-360), 12 (1-156), 22 (0-216), and 60 months, respectively. Fifty percent of CDD could succeed only under local anaesthesia, RYHJ (96.7%) and Whipple (100.0%) needed under general anaesthesia (P < 0.001). Successful first entry rates of CDD, RYHJ and Whipple were 100.0%, 40.0% and 77.8%, respectively. After changing the endoscopy type, successful entry rate could increase to 43.3% of RYHJ and 83.3% of Whipple. The successful entry rate of different anastomotic methods was significant (P < 0.001). The cannulation success rates of CDD, RYHJ and Whipple were 100.0%, 53.8% and 86.7% respectively, with significant difference between the groups (P=0.031). ERCP success rates of CDD, RYHJ and Whipple were 100.0%, 33.3% and 78.8% respectively, with significant difference between the groups (P < 0.001). Complications were found in 23.9% (21/88) patients, including infection (14.8%), pancreatitis (9.2%), bleeding (3.4%), and perforation (2.3%) ranked by incidence. Causes of ERCP in post bilioenteric anstomosis were anastomotic stenosis (50.0%, benign 39.3%, malignant 10.7%), choledocholithiasis (37.5%) and reflux cholangitis (12.5%). Anastomotic method was the only predicting factor of ERCP success in patients after bilioenteric anstomosis (OR=7, 95%CI: 2.591-18.912, P < 0.001). CONCLUSION ERCP in post bilioenteric anstomosis patients with gastrointestinal reconstruction need general anaesthe-sia, with good safety and efficiency. The successful rate of RYHJ was significantly lower than Whipple. Anastomotic method was the only predicting factor of ERCP success.

BACKGROUND: Endoscopic retrograde cholangiopancreatography (ERCP) is the endoscopic modality of choice for the treatment of biliary and pancreatic diseases. However, patients with cirrhosis, particularly those with decompensated cirrhosis, are believed to be at increased risk for complications associated with ERCP. There is a paucity of literature describing the outcomes of ERCP for patients with cirrhosis. This study aimed to investigate the outcomes of ERCP for cirrhosis patients, especially adverse events, and evaluated its safety and efficacy. METHODS: We performed a multicenter, retrospective study of all patients at Beijing Friendship Hospital affiliated to Capital Medical University, Xijing Hospital affiliated to Air Force Military Medical University, Beijing Youan Hospital affiliated to Capital Medical University, and the Fifth Medical Center of the People's Liberation Army General Hospital from June 2003 to August 2019. The adverse events of inpatient ERCP for patients with ( n  = 182) and without liver cirrhosis (controls; n  = 385) were compared. RESULTS: A total of 567 patients underwent ERCP between January 2003 and December 2019 were enrolled in this study. Compared to patients without cirrhosis, patients with cirrhosis were at higher risk for postoperative complications (odds ratio [OR], 4.172; 95% confidence interval [CI], 1.232-7.031; P  < 0.001) such as postoperative pancreatitis (OR, 2.026; 95% CI, 1.002-4.378; P  = 0.001) and cholangitis (OR, 3.903; 95% CI, 1.001-10.038; P  = 0.036). The main indications for ERCP for patients with cirrhosis in this study included choledocholithiasis (101 cases; 55.5%), benign bile duct strictures (46 cases; 25.3%), and malignant bile duct strictures (28 cases; 15.4%). Among them, 23 patients (12.6%) underwent balloon dilation and 79 patients (43.4%) underwent sphincterotomy. Of the patients with cirrhosis, delayed bleeding occurred in ten patients (5.5%), postoperative pancreatitis occurred in 80 patients (44.0%), and postoperative cholangitis occurred in 25 patients (13.7%). An additional multivariate analysis showed that the total bilirubin (TBIL) level (OR, 4.58; 95% CI, 2.37-6.70) and Child-Pugh score of C (OR, 3.11; 95% CI, 1.04-5.37) were risk factors for postoperative complications in patients with cirrhosis. CONCLUSIONS Compared with the general population of patients undergoing ERCP, patients with cirrhosis were more prone to postoperative pancreatitis and cholangitis. TBIL levels and Child-Pugh scores were risk factors for postoperative complications in patients with cirrhosis.

Endobiliary radiofrequency ablation (RFA) is a procedure performed widely to induce locoregional tumor control by the transfer of thermal energy to the lesion and subsequent tumor necrosis. A 72-year-old male with a prior history of acute calculous cholangitis and perforated cholecystitis was admitted to the Kyungpook National University Hospital complaining of fever and nausea. He had an indwelling percutaneous transhepatic gallbladder drainage (PTGBD) catheter from the previous episode of perforated cholecystitis. An abdominal CT scan showed marked dilation of both the intrahepatic and extrahepatic bile ducts. Common bile duct cancer was confirmed histologically after an endobiliary biopsy. A surgical resection was considered to be the initial treatment option. During open surgery, multiple metastatic nodules were present in the small bowel mesentery and anterior abdominal wall. Resection of the tumor was not feasible, so endobiliary RFA was performed prior to biliary stenting. Cholecystectomy was required for the removal of the PTGBD catheter, but the surgical procedure could not be performed due to a cystic ductal invasion of the tumor. Instead, chemical ablation of the gallbladder (GB) with pure ethanol was performed to breakdown the GB mucosa. Palliative treatment for a biliary obstruction was achieved successfully using these procedures. In addition, a PTGBD catheter was removed successfully without significant side effects. As a result, an improvement in the patient's quality of life was accomplished.

Acute pancreatitis(AP)is an inflammatory condition of the pancreas following the activationt of pancreatic enzymes induced by a variety of factors,with or without other organ dysfunction.The production and release of inflammatory factors is generally considered as a key link during pathogenesis.Non-steroidal anti-inflammatory drugs(NSAIDs)are the most commonly applied agents for inflammatory diseases.Many studies have proved that indomethacin can reduce the risk of pancreatitis after endoscopic retrograde cholangiopancreatography;however,few high-quality evidences have demonstrated the roles of NSAIDs in treating,rather than preventing AP.Most animal experiments have shown that NSAIDs can protect organs,although the currently available findings remained inconsistent.Randomized controlled trials with large sample sizes are warranted to elucidate the roles of NSAIDs in treating AP.

Pancreatic cancer is a major cause of cancer-related mortality and morbidity, and its incidence is increasing as the population is aging. On the other hand, significant improvement in the prognosis has not occurred. The absence of early diagnosis means that many patients are diagnosed only when they develop symptoms, such as jaundice, due to a biliary obstruction. The role of endoscopy in multidisciplinary care for patients with pancreatic cancer continues to evolve. Controversy remains regarding the best preoperative biliary drainage in patients with surgically resectable pancreatic head cancer. In general, patients undergoing a surgical resection usually do not require preoperative biliary drainage unless they have cholangitis or receive neoadjuvant chemotherapy. If biliary drainage is performed prior to surgery, the patient's condition and a multidisciplinary approach should be considered. With the increasing life expectancy of patients with pancreatic cancer, the need for more long-time biliary drainage or pre-operative biliary drainage is also increasing. Strong evidence of endoscopic retrograde cholangiopancreatography (ERCP) as a first-line and essential treatment for biliary decompression has been provided. On the other hand, the use of endoscopic ultrasound-guided biliary drainage as well as percutaneous biliary drainage has been also recommended. During ERCP, self-expandable metal stent could be recommended instead of a plastic stent for the purpose of long stent patency and minimizing stent-induced complications. In this review, several points of view regarding the relief of obstruction in patients with pancreatic cancer, and optimal techniques are being discussed.

The malignant degree of cholangiocarcinoma is high, and the early diagnosis is difficult. The vast majority of patients are unresectable when they are diagnosed. The patients have low quality of life and short survival cycle. Traditional radiotherapy and chemotherapy have poor efficacy and lead to side effects, and thus lack effective control measures for cholangiocarcinoma. Endoscopic retrograde cholangiopancreatography (ERCP) is an important method for diagnosing and treating biliary tract diseases. Photodynamic therapy (PDT) is a new local treatment for cholangiocarcinoma. In recent years, ERCP-mediated PDT treatment of cholangiocarcinoma has gradually emerged. ERCP-mediated PDT can effectively relieve the symptoms of patients with cholangiocarcinoma, improve the patients' quality of life, prolong the survival cycle, and is expected to become a new treatment for cholangiocarcinoma.
