RESUMO
Background/Aims@#This study aimed to investigate the patterns of preferred endoscopic procedure types and techniques for managing difficult common bile duct (CBD) stones in South Korea. @*Methods@#The Committee of Policy and Quality Management of Korean Pancreatobiliary Association (KPBA) conducted a survey containing 19 questions. Both paper and online surveys were carried out; with the paper survey being conducted during the 2019 Annual Congress of KPBA and the online survey being conducted through Google Forms from April 2020 to February 2021. @*Results@#The response rate was approximately 41.3% (86/208). Sixty-two (73.0%) worked at tertiary hospitals or academic medical centers, and 60 (69.7%) had more than 5 years of endoscopic retrograde cholangiopancreatography experience. The preferred size criteria for large CBD stones were 15 mm (40.6%), 20 mm (31.3%), and 30 mm (4.6%). For managing of large CBD stones, endoscopic papillary large balloon dilation after endoscopic sphincterotomy was the most preferred technique (74.4%). When performing procedures in those with bleeding diathesis, 64 (74.4%) respondents favored endoscopic papillary balloon dilation (EPBD) alone or EPBD with small endoscopic sphincterotomy. Fifty-five respondents (63.9%) preferred the doubleguidewire technique when faced with difficult bile duct cannulation in patients with periampullary diverticulum. In surgically altered anatomies, cap-fitted forward viewing endoscopy (76.7%) and percutaneous transhepatic cholangioscopy (48.8%) were the preferred techniques for Billroth-II anastomosis and total gastrectomy with Roux-en-Y anastomosis, respectively. @*Conclusions@#Most respondents showed unifying trends for the management of difficult CBD stones. The current practice patterns could be used as basic data for clinical quality improvements in the management of difficult CBD stones.
RESUMO
Background/Aims@#Although endoscopic ultrasound (EUS)-guided fine needle aspiration (FNA) and fine needle biopsy (FNB) are widely used for tissue acquisition of pancreatic solid mass, the optimal strategy of this procedure has not been established yet. The aim of this nationwide study was to investigate the current practice patterns of EUS-FNA/FNB for pancreatic solid mass in Korea. @*Methods@#The Policy-Quality Management of the Korean Pancreatobiliary Association (KPBA) developed a questionnaire containing 22 questions. An electronic survey consisting of the questionnaire was distributed by e-mail to members registered to the KPBA. @*Results@#A total of 101 respondents completed the survey. Eighty respondents (79.2%) performed preoperative EUS-FNA/FNB for operable pancreatic solid mass. Acquire needles (60.4%) were used the most, followed by ProCore needles (47.5%). In terms of need size, most respondents (>80%) preferred 22-gauge needles regardless of the location of the mass. Negative suction with a 10-mL syringe (71.3%) as sampling technique was followed by stylet slow-pull (41.6%). More than three needle passes for EUS-FNA/FNB was performed by most respondents (>80%). The frequency of requiring repeated procedure was significantly higher in respondents with a low individual volume (<5 per month, p=0.001). Prophylactic antibiotics were routinely used in 39 respondents (38.6%); rapid on-site pathologic evaluation was used in 6.1%. @*Conclusions@#According to this survey, practices of EUS-FNA/FNB for pancreatic solid mass varied substantially, some of which differed considerably from the recommendations present in existing guidelines. These results suggest that the development of evidence-based quality guidelines fitting Korean clinical practice is needed to establish the optimal strategy for this procedure.
RESUMO
Background/Aims@#Endoscopic ultrasonography (EUS) provides high-resolution images and is superior to computed tomography (CT) scan in diagnosing small pancreatic ductal adenocarcinoma (PDAC). As a result, the use of EUS for early detection of PDAC has attracted attention. This study aimed to identify the clinical and radiological characteristics of patients with PDAC diagnosed by EUS but not found on CT scan. @*Methods@#The medical records of patients diagnosed with PDAC at 12 tertiary referral centers in Korea from January 2003 to April 2019 were reviewed. This study included patients with pancreatic masses not clearly observed on CT scan but identified on EUS. The clinical characteristics and radiological features of the patients were analyzed, and survival analysis was performed. @*Results@#A total of 83 patients were enrolled. The most common abnormal CT findings other than a definite mass was pancreatic duct dilatation, which was identified in 61 patients (73.5%). All but four patients underwent surgery. The final pathologic stages were as follows: IA (n=31, 39.2%), IB (n=8, 10.1%), IIA (n=20, 25.3%), IIB (n=17, 21.5%), III (n=2, 2.5%), and IV (n=1, 1.4%). The 5-year survival rate of these patients was 50.6% (95% confidence interval, 38.8% to 66.7%). Elevated liver function testing and R1 resection emerged as significant predictors of mortality in the multivariable Cox regression analysis. @*Conclusions@#This multicenter study demonstrated favorable long-term prognosis in patients with PDAC diagnosed by EUS but indeterminate on CT scan. EUS should be considered for patients with suspected PDAC but indeterminate on CT scan.
RESUMO
Background/Aims@#Biliary complications including biliary strictures and bile leaks are the most common complications that occur after liver transplantation (LT). Endoscopic treatment with endoscopic retrograde cholangiography (ERC) is considered the first-line treatment, and percutaneous transhepatic cholangiography (PTC) can serve as an alternative or rescue therapy.However, nationwide clinical data on the frequency of ERC and PTC following LT have not yet been investigated. @*Methods@#Using the nationwide claims database, we investigated patients who underwent LT between 2012 and 2014 in Korea and followed them until 2015. We analyzed the prevalence and characteristics of patients and biliary procedures, including ERC and PTC implemented after LT. @*Results@#A total of 3,481 patients underwent LT during the 3-year study period. Among them, 3.0% of patients underwent biliary intervention postoperatively during the same hospitalization period, and 21.4% of patients received biliary intervention later on after initially being discharged from the hospital following LT. A total of 16.9% and 12.1% of patients underwent ERC and PTC after LT, respectively. The median period from LT to the first biliary intervention was 7.8 months (interquartile range, 3.5 to 14.6 months), and these patients underwent an average of 3.2±2.8 biliary procedures during the follow-up period. Patients undergoing living donor LT were more than twice as likely to undergo biliary procedures as those undergoing deceased donor LT (25.5% vs 12.1%). @*Conclusions@#Approximately one-fourth of patients in Korea who underwent LT subsequently underwent ERC or PTC. Compared with deceased donor LT patients, those undergoing living donor LT underwent more biliary interventions and were more difficult to treat.
RESUMO
Background/Aims@#The coronavirus disease 2019 (COVID-19) outbreak caused numerous social and cultural changes, but few studies focused on their effects on gastroenterology (GI) fellowship training. This study evaluated the impact of COVID-19 on GI fellowship training. @*Methods@#A web-based questionnaire was sent out to GI fellows in Korea between 15 February and 15 March 2021. The questionnaire included questions regarding the characteristics of GI fellows, perception of COVID-19 outbreak, impact of COVID-19 outbreak, and telemedicine on the education of a GI fellowship. @*Results@#Among 111 answers, 94 respondents were analyzed. The GI fellows were provided with sufficient information about the COVID-19 outbreak (74.7%), well educated, and provided with personal protective equipment use (74.7% and 83.9%, respectively).On the other hand, outpatient schedule and volume decreased in 25.5% and 37.8% of respondents, respectively. Moreover, endoscopy sessions and volume decreased in 51.1% and 65.6% of respondents, respectively. As a result, 78.9% of respondents were concerned that the COVID-19 outbreak adversely affected their education. Telemedicine utilization was introduced during the COVID-19 outbreak, but only 20.0% and 10.6% of respondents agreed that telemedicine has benefits from the patient’s and doctor’s perspectives, respectively. In addition, only 25.9% of respondents were willing to continue telemedicine if adequately reimbursed, and 68.2% of respondents were concerned that it adversely affected their education. @*Conclusions@#The COVID-19 outbreak has adversely affected GI fellowship training in Korea for outpatient clinics, gastrointestinal endoscopy, educational conferences, and telemedicine. This study highlights that GI fellowship training needs more attention in the COVID-19 outbreak.
RESUMO
Background@#/Aim: Endoscopic retrograde choangiopancreatography (ERCP) has been established as an effective tool for the diagnosis and treatment of pancreatobiliary diseases. However, after the evolution for more than 4 decades, nationwide data on current trends and characteristic is not well known. Therefore, we conducted an analysis of nationwide database to determine the number and status of ERCP performed in Korea. @*Methods@#We used the nationwide claims database, Korean Health Insurance Review and Assessment between 2012 and 2015. We investigated the frequencies and characteristics of ERCP procedure performed as well as demographics of the patients. @*Results@#A total of 158,038 ERCP procedures were performed in 114,757 patients during study period. The number of total ERCPs increased every year, and especially the rate of therapeutic ERCPs is on the increased trend. About two-thirds of ERCPs (63.3%) were performed in high-scaled hospitals. In 2015, the proportion of elderly patients over 80 years old increased compared to that in 2011, from 14.3% to 17.2%. @*Conclusions@#The annual number of ERCPs performed is increasing in Korea. With increasing ERCP for therapeutic purposes or for older patients, more attention should be paid to safety for patients.

RESUMO
Background/Aims@#Treatment of residual intraductal lesions after endoscopic papillectomy for ampullary adenomas is relatively difficult. Few studies have been conducted using intraductal radiofrequency ablation (RFA) in the treatment of such lesions, and no study has aimed to reduce the side effects of excessive heat caused by RFA. Recently, a temperature-controlled RFA probe was developed to avoid excessive heat. This study aimed to investigate the safety of this new RFA probe in the treatment of intraductal lesions of ampullary adenoma. @*Methods@#Patients who received RFA for residual intraductal lesions after endoscopic papillectomy between November 2017 and June 2019 were retrospectively reviewed. A novel temperature-controlled probe (ELRA) was used for intraductal RFA, and clinical data including adverse events were collected. @*Results@#Ten patients were included in this study. Intraductal adenomas showed low-grade dysplasia in eight patients and high-grade dysplasia in two patients. The median diameter of intraductal adenomas was 9 mm (range, 5 to 10 mm) in the common bile duct and 5 mm (range, 4 to 11 mm) in the pancreatic duct. Adverse events occurred in three patients (30.0%), of which two were mild pancreatitis and one was asymptomatic biliary stricture. Over a median follow-up period of 253 days, only one patient underwent additional surgery, as the remainder showed no adenomatous lesions on follow-up biopsies. @*Conclusions@#The new temperature-controlled RFA probe can be used with acceptable safety for the treatment of residual intraductal lesions after endoscopic papillectomy. Further evaluation through future prospective studies is needed.
RESUMO
Pancreatic Fluid Collection (PFC) develops as a result of acute pancreatitis, chronic pancreatitis, trauma, and postoperation. Although percutaneous drainage, surgery and Endoscopic Retrograde Panceatogram are used as conventional treatments in complicated PFC, the clinical course of PFC is unsatisfactory due to its clinical success rate and the risk of procedure-related complications. Endoscopic ultrasonography-guided transmural drainage of PFC is a safe and effective modality for the management of PFC, particularly in patients with pancreas necrosis. A range of techniques and stents have been introduced and a newly designed metal stent is now available.

Gastric cancer frequently disseminates to the liver, lung, and bone via hematogeneous, lymphatic, or peritoneal routes. However, gastric adenocarcinoma that metastasize to the colon and that shows typical linea platisca pattern on colonofiberscopy has rarely been reported. Recently, the authors experience a case of advanced gastric cancer with colonic metastases in a 55-year-old female patient. Multiple colonic lymphoid hyperplasias were detected on colonofiberscopy and biopsy revealed metastatic gastric cancer to the colonic wall. She was treated with mFOLFOX (5-FU, oxaliplatin, leucovorin) and has achieved stable disease status without disease progression. Herein, we report a rare case of signet ring-cell gastric cancer which metastasized to the colon in the form of multiple colonic lymphoid hyperplasias.

Birt-Hogg-Dube (BHD) syndrome is a rare, autosomal-dominant disorder that is caused by germ-line mutations in the folliculin gene. Clinically, BHD syndrome is characterized by cutaneous follicle tumors, pulmonary cysts, spontaneous pneumothorax, and an increased risk of renal cancer. A 65-year-old woman was admitted to Seoul St. Mary's Hospital to treat pneumonia, and we found that she had experienced recurrent spontaneous pneumothorax and had bilateral multiple pulmonary cysts with no history of smoking. Mutation analysis of the folliculin gene identified a novel mutation in exon 9 (c.997_998delTC; p.Ser333ArgfsX56). Except for the lung manifestation, no other features of BHD syndrome were detected in this case. Here, we report a case of BHD syndrome that manifested only as lung disease with a novel mutation.

Acinetobacter species is a non-fermentative aerobic gram-negative coccobacillus that is an important pathogen found in nosocomial infections. Recently, multi-drug resistant Acinetobacter baumannii (MDR-AB) infections have been increasing and pose a serious problem. Most such infections present as bacteremia, pneumonia, or a wound infection; however, CNS infections are very rare. We herein present a case of ventriculitis caused by MDR-AB in a 37-year old man after a neurosurgical intervention. The patient was successfully treated with intrathecal colistimethate.

Hepatocellular calcinoma (HCC) is the fifth most common cancer and the third leading cause of cancer-related deaths worldwide. It is important to diagnose HCC exactly before management is attempted. But, the clinical presentations and radiologic findings of liver abscess, HCC, and metastatic tumor to the liver may be quite similar, and procedures such as serum tumor marker assay, computerized tomography, and ultrasonography of the liver cannot make a specific diagnosis. We report a case of HCC successfully diagnosed by surgery which was misconceived as liver abscess and not improved by medical treatment.
