BACKGROUND/AIMS: The landscape of sedation for gastrointestinal (GI) endoscopic procedures and the nature of the procedures themselves have changed over the last decade. In this study, an attempt is made to analyze the frequency and etiology of all major adverse events associated with GI endoscopy. METHODS: All adverse events extracted from the electronic database and local registry were analyzed. Although the data analysis was retrospective, the adverse events themselves were documented prospectively. These events were evaluated after subdivision into propofol-based anesthesia and intravenous conscious sedation groups. RESULTS: Cardiorespiratory events, including cardiac arrest, were the most common adverse events during esophagogastroduodenoscopy, while bleeding was more frequent in patients undergoing colonoscopy. Pancreatitis was the most frequent adverse event in patients undergoing endoscopic retrograde cholangiopancreatography. The frequencies of most adverse events were significantly higher in patients anesthetized with propofol. Automatic regression modeling showed that the type of sedation, the American Society of Anesthesiologists physical status classification, and the procedure type were some of the predictors of immediate life-threatening complications. CONCLUSIONS: Clearly, our regression modeling suggests a strong association between the type of sedation as well as various patient factors and the frequency of adverse events. The possible reasons for our results are the changing demographics, the worsening comorbidities of the patient population, and the increasing technical complexity of these procedures. Although extensive use of propofol has increased patient satisfaction and procedure acceptability, its use is also associated with more frequent adverse events.

Endoscopic ultrasonography (EUS)-a combination of endoscopy a.nd ultrasonography was one of the most useful tools for diagnosis of digestive system diseases. This technique was known to be very effective in the assessment of depth of invasion in gastric cancer and in pancreatico-biliary diseases. We performed EUS in 589 patients with upper gastrointestinal and pancreatico-biliary tract lesion prior to surgery for past 22 months and examined the diagnostic accuracy of EUS, respectively. The results were compared to surgical histology in esophagus and stomach cancer,to concordance witb endoscopic retrograde cholangiopancreatography(ERCP) results for pancreaticobiliary diseases. 1) In 589 patients diagnosed with EUS, the mean age of the patients was 55.9 years with a male to female ratio of 1.7: 1. 2) Patients were divided into three groups; post-upper gastrointestinal endoscopy, post ERCP and undiagnosed with other diagnostic tools. 3) Among post-upper gastrointestinal endoscopy, 64 cases were operated due to esophageal and gastric cancer and then compared to surgical histology. After compared, EUS accuracy on depth of invasion was 78.1% and sensitivity and specificity on lymph node metastasis in gastric cancer were 76.9% and 74.3%, respectively. 4) In post-ERCP cases, EUS results were compared to ERCP results and then concordance rate was 95.4%. 5) In undiagnosed cases, EUS was performed and results were reported.

Gastrointestinal stromal tumors (GISTs) are common mesenchymal tumors that arise in the wall of the gastrointestinal tract. We report a case of obscure gastrointestinal bleeding due to a GIST of the jejunum successfully documented by videocapsule endoscopy (VCE) and single-balloon enteroscopy (SBE). A 36-year-old man with hematochezia was referred for further evaluation of no evidence of bleeding focus on esophagogastroduodenoscopy and colonoscopy. A VCE showed a suspicious ulcerative hyperemic mass that located in about 1 hour apart from duodenal second portion. SBE revealed a nonbleeding 4x2 cm mass with an ulcer at the proximal jejunum. The patient underwent laparoscopic resection without complication. Histological examination revealed a well circumscribed, dumbbell-shaped firm mass comprised of spindle cells. Immunohistochemical staining for CD 117 was diffusely positive, whereas staining for S-100, CD 34 and MIB-1 was all negative. It was confirmed to be a low-grade GIST at the proximal jejunum.

An inflammatory fibroid polyp (IFP) is a mesenchymal tumor of the gastrointestinal tract. IFPs in the small intestine are the most frequently detected with symptoms, such as abdominal pain and tarry stool due to intussusception. Accordingly, few studies have reported jejunal IFP as a cause of occult gastrointestinal bleeding (OGIB) diagnosed via both of capsule endoscopy (CE) and double-balloon enteroscopy (DBE). A 68-year-old woman presented with a progression of anemia and a positive fecal occult blood test result. Esophagogastroduodenoscopy and total colonoscopy findings were unremarkable. CE revealed a tumor with bleeding in the jejunum. DBE also revealed a jejunal polypoid tumor. Bleeding from the tumor seemed to have caused anemia. The patient underwent partial laparoscopic resection of the jejunum, including resection of the tumor. The tumor was histopathologically diagnosed as IFP. To our knowledge, this is the first reported case of laparoscopic resection of jejunal IFP with OGIB diagnosed via CE and DBE preoperatively.

5.Should Capsule Endoscopy Be the First Test for Every Obscure Gastrointestinal Bleeding?.
Clinical Endoscopy 2014;47(5):409-414
Obscure gastrointestinal bleeding (OGIB) refers to gastrointestinal (GI) bleeding of unclear origin that persists or recurs after negative findings on esophagogastroduodenoscopy and colonoscopy. OGIB accounts for approximately 5% of all types of GI bleeding. More than 80% of OGIB cases originate in the small bowel. The ability to detect OGIB in the small bowel has significantly advanced and been revolutionized since the introduction of the capsule endoscopy and double-balloon enteroscopy techniques in 2000 and 2001, respectively. With these new methods for small-bowel evaluation, new guidelines have been proposed for the diagnosis and management of OGIB. However, some issues remain unsolved. The purpose of this article is to review the various modalities used for evaluating OGIB, including capsule endoscopy and double-balloon enteroscopy, and to help guide clinicians in their decisions on which modality will be the most effective.

BACKGROUND:
Worldwide, the volume and availability of digestive endoscopy have undergone dramatic development in recent years, with increasing attention on quality assurance. We investigated the utilization and quality of digestive endoscopy in China from 2015 to 2019 and developed a quantitative quality evaluation tool for medical institutions.
METHODS:
We invited all tertiary/secondary hospitals in Chinese mainland to participate in the survey annually. The questionnaires included the personnel, annual volume, and quality indicators of endoscopy. An endoscopy quality index (EQI) was developed based on recorded quality indicators using principal component analysis to determine the relative weight.
RESULTS:
From 2015 to 2019, 806, 1412, 2644, 2468, and 2541 hospitals were respectively enrolled in this study. The average annual volume of endoscopy increased from 12,445 to 16,206 (1.30-fold) and from 2938 to 4255 (1.45-fold) in tertiary and secondary hospitals, respectively. The most obvious growth was observed in diagnostic colonoscopy (1.44-fold for all hospitals after standardization). The proportion of early cancer among all esophageal and gastric cancers during diagnostic esophagogastroduodenoscopy increased from 12.3% (55,210/448,861) to 17.7% (85,429/482,647) and from 11.4% (69,411/608,866) to 16.9% (107,192/634,235), respectively. The adenoma detection rate of diagnostic colonoscopy increased from 14.9% (2,118,123/14,215,592) to 19.3% (3,943,203/20,431,104). The EQI model included 12 quality indicators, incorporating 64.9% (7.792/12) of the total variance into one comprehensive index. According to the EQI measurements, the quality of endoscopy was higher in tertiary hospitals and hospitals in developed areas with higher volume or more endoscopists than that in other hospitals.
CONCLUSIONS
Digestive endoscopy in China has developed considerably in recent years in terms of both volume and quality. The EQI is a promising tool to quantify the quality of endoscopy at different hospitals.

BACKGROUND/AIMS: There has been no evidence for the necessity of endoscopy in asymptomatic young men with iron deficiency anemia (IDA). To determine whether endoscopy should be recommended in asymptomatic young men with IDA, we compared the prevalence of gastrointestinal (GI) lesions between young men (< 50 years) with IDA and those without IDA. METHODS: We conducted a case-control study on asymptomatic young men aged < 50 years who underwent both esophagogastroduodenoscopy (EGD) and colonoscopy as part of a health checkup between 2010 and 2014. RESULTS: Of 77,864 participants, 128 (0.16%) had IDA and 512 subjects without IDA were matched for several variables including age. Young men with IDA had a significantly higher proportion of colorectal cancer (CRC) (0.8% vs. 0.0%, p = 0.045), villous adenoma (0.8% vs. 0.0%, p = 0.045), and inflammatory bowel disease (IBD; 2.3% vs. 0.4%, p = 0.025) than those without IDA. Additionally, the prevalence of advanced colorectal neoplasia (ACRN) tended to be higher in subjects with IDA than in those without IDA (3.1% vs. 1.0%, p = 0.084). The prevalence of significant lower GI lesions including ACRN and IBD was higher in subjects with IDA than in those without IDA (5.5% vs. 1.4%, p = 0.011). Regarding upper GI lesions, a positive association with IDA was observed only for gastric ulcer (4.7% vs. 1.0%, p = 0.011). CONCLUSIONS: GI lesions including CRC, villous adenoma, IBD, and gastric ulcer were more common in asymptomatic young men with IDA. Our results suggest that EGD and particularly colonoscopy should be recommended even in asymptomatic young men with IDA.

Clinical Endoscopy 2017;50(4):318-321
Gastrointestinal endoscopy is important in diagnosis, treatment, and prevention of many diseases of the digestive tract. The ability to perform esophagogastroduodenoscopy (EGD) safely, effectively, and efficiently has become the mainstay of gastroenterology practice. In Korea, EGD education is usually imparted as a component of gastroenterology training programs during fellowship. In this review, we discuss the general principles of EGD training. Formal curriculum development with devising clear goals and effective training methods should be developed in the future.

Journal of Gastric Cancer 2011;11(4):239-242
A debate is currently ongoing about whether a large gastrointestinal stromal tumor (GIST) should be treated by the laparoscopic approach because of the increased risk of tumor rupture during manipulation of the tumor with laparoscopic instruments and the resultant peritoneal tumor dissemination. Herein, we report a case of a large GIST of the stomach which was successfully treated by the laparoscopic approach. A 57 year old female patient visited our institution complaining of postprandial epigastric discomfort. An esophagogastroduodenoscopy and an abdominal computed tomography scan revealed a 10x8 cm sized submucosal tumor at the greater curvature side of the gastric antrum. The patient underwent laparoscopic distal gastrectomy with intracorporeal Billroth-II reconstruction without any breakage of the tumor. Her postoperative course was uneventful and she was discharged on the 7th postoperative day. Even a large GIST of the stomach can safely be treated by the laparoscopic approach when it is performed with proper techniques by an experienced surgeon.
