Gastroenterology

Endoscopic ultrasound has become an essential tool in modern gastroenterology and abdominal surgery. Compared with all other endoscopic methods, it has the most potential for innovation and its future looks bright. Thus, we compiled this summary of established and novel applications of endoscopic ul..

Background/Aims: Endoscopic resection (ER) is a well-established treatment modality for gastric epithelial neoplasm. However, there is a discrepancy between forceps biopsy and ER specimen pathology, including a negative pathologic diagnosis (NPD) after ER. It has been suggested that pit dysplasia (P..

Background/Aims: Despite improvements in surgical techniques and postoperative patient care, bile leakage can occur after hepatobiliary surgery and may lead to serious complications. The aim of this retrospective study was to evaluate the efficacy of endoscopic treatment of bile leakage after hepato..

Background/Aims: To compare the diagnostic accuracy of endoscopic ultrasound-guided core needle aspiration with that of standard fine-needle aspiration by systematic review and meta-analysis. Methods: Studies using 22/25-gauge core needles, irrespective of comparison with standard fine needles, wer..

Background/Aims: Endoscopic submucosal dissection (ESD) of a superficial esophageal neoplasm (SEN) is a technically difficult procedure. We investigated the clinical outcomes of ESD to determine its feasibility and effectiveness for the treatment of SEN. Methods: Patients who underwent ESD for SEN ..

Background/Aims: Endoscopic retrograde biliary drainage (ERBD) has become a standard procedure in patients with a biliary obstruction. Intraductal ultrasonography (IDUS) has emerged as a new tool for managing extrahepatic biliary diseases. IDUS-directed ERBD can be performed without conventional cho..

Background/Aims: To evaluate the therapeutic outcomes of the endoscopic submucosal dissection (ESD) technique for the treatment of gastric subepithelial tumors (SETs). Methods: A systematic literature review was conducted using the core databases. Data on the complete resection rates and the proced..

Background/Aims: This study was performed to investigate the clinical role of urgent esophagogastroduodenoscopy (EGD) for acute nonvariceal upper gastrointestinal bleeding (ANVUGIB) performed by experienced endoscopists after hours. Methods: A retrospective analysis was performed for consecutively ..

Background/Aims: Acute pancreatitis is a common complication of endoscopic retrograde cholangiopancreatography (ERCP). Combination therapy w ith ora l udenafil and aceclofenac may reduce the occurrence of post-ERCP pancreatitis by targeting different pathophysiological mechanisms. We investigated wh..

Background/Aims: To evaluate the efficacy of proton pump inhibitors (PPIs) in reducing rebleeding and bleeding-related death rates after endoscopic gastric variceal obliteration (GVO) using N-butyl-2-cyanoacrylate (NBC). Methods: This study enrolled 341 patients who were consecutively diagnosed wi..

Acute pancreatitis remains the most frequent complication of endoscopic retrograde cholangiopancreatography (ERCP), with reported incidence rates that have changed little over several decades. Patient- and procedure-related risk factors for post-ERCP pancreatitis (PEP) are well-defined. Effective..

Hilar cholangiocarcinoma has an extremely poor prognosis and is usually diagnosed at an advanced stage. Palliative management plays an important role in the treatment of patients with inoperable hilar cholangiocarcinoma. Surgical, percutaneous, and endoscopic biliary drainage are three modalities..

Chronic pancreatitis (CP) is a debilitating disease that can result in chronic abdominal pain, malnutrition, and other related complications. The main aims of treatment are to control symptoms, prevent disease progression, and correct any complications. A multidisciplinary approach involving medi..

Endoscopic papillary balloon dilation (EPBD) is a safe and effective method for the treatment of choledocholithiasis, but previous studies have rarely reported the appropriate ballooning time (BT). We prospectively evaluated the safety and efficacy of EPBD accor..

Although a few recent studies have reported the effectiveness of endoscopic pancreatic sphincterotomy (EPST), none has compared physicians' skills and complications resulting from the procedure. Thus, we examined the indications, complications, and safety of EPS..

Endoscopic therapy has been increasingly recognized as the effective therapy in selected patients with chronic pancreatitis. Utility of endotherapy in various conditions occurring in chronic pancreatitis is discussed. Its efficacy, limitations, and alternatives are addressed. For the best managem..

Techniques for endoscopic evaluation of gastrointestinal subepithelial lesions include conventional endoscopy, jumbo biopsy, endoscopic ultrasonogrphy (EUS), EUS-guided fine needle aspiration, and endoscopic submucosal resection. However, these procedures have m..

It has been recently reported that celiac ganglia can be identified by linear-array endoscopic ultrasonography (EUS). Still, there has been no report on the detection rate of celiac ganglia with radial scanning EUS. The aim of this study was to evaluate the dete..

Lung cancer metastases can occur in almost any organ. However, metastasis of small cell lung cancer to the pancreas is rare. Moreover, not all cases present with clinically diagnosed pancreatitis. We recently treated a patient with small cell lung carcinoma that invaded the pancreatic duct causin..
