Gastrointestinal (GI) endoscopy plays an indispensable role in the diagnosis and management of various pediatric GI disorders. While the pace of development of pediatric GI endoscopy has increased over the years, it remains sluggish compared to the advancements in GI endoscopic interventions available in adults. The predominant reasons that explain this observation include lack of formal training courses in advanced pediatric GI interventions, economic constraints in establishing a pediatric endoscopy unit, and unavailability of pediatric-specific devices and accessories...

Cholangitis is a serious life-threatening situation affecting the hepatobiliary system. This review provides an update regarding the clinical and pathological features of various forms of cholangitis. A comprehensive search was performed in the PubMed, Scopus, and Web of Knowledge databases. It was found that the etiology and pathogenesis of cholangitis are heterogeneous. Cholangitis can be categorized as primary sclerosing (PSC), secondary (acute) cholangitis, and a recently characterized form, known as IgG4-associated cholangitis (IAC)...

BACKGROUND: Gallbladder cancer (GBC) has been contraindicated for laparoscopic surgery since this procedure was introduced [1, 2]. Recently, however, there have been several reports of laparoscopic extended cholecystectomy for GBC, but most cases involved early GBC confined to the GB [3, 4]. This video describes our technique of laparoscopic extended cholecystectomy for T3 GBC. METHODS: A 77-year-old female presented with a gallbladder mass, which was incidentally detected during evaluation of back pain...

A 65-year-old male was referred to our hospital 2 years ago for a multilocular cyst accompanied with a protein plug in the pancreas tail. He was diagnosed as having branch duct-type intraductal papillary mucinous neoplasm and was followed-up. Two years later, endoscopic ultrasonography revealed a hypoechoic lesion, 10mm in diameter, near the cyst-like lesion. Finally, he was diagnosed with small pancreatic adenocarcinoma concomitant with intraductal papillary mucinous neoplasm and underwent radical distal pancreatectomy with splenectomy...

A 73-year-old man was incidentally diagnosed with a cystic lesion in the pancreatic body. Ultrasonography, abdominal computed tomography, magnetic resonance imaging, endoscopic retrograde cholangiopancreatography, and endoscopic ultrasound were performed, and a nodule was detected in the cystic lesion along with an irregularity of the main pancreatic duct. An initial diagnosis of a mixed-type intraductal papillary mucinous neoplasm was made, and a central pancreatectomy was performed. However, the final diagnosis was altered to non-invasive intraductal papillary mucinous carcinoma (IPMC)...

REVIEW

Pancreatic neuroendocrine tumors (PNETs) are relatively rare; however, the incidence has increased over the last few decades. They are classified as functional or non-functional tumors according to the presence of associated clinical symptoms. The majority are non-functional tumors. For classification and staging, the World Health Organization 2010 classification system is the most commonly accepted. Chromogranin A is the most sensitive marker but has insufficient specificity. In general, PNETs are hypervascular tumors, and multiphasic contrast-enhanced computed tomography is considered the first choice for imaging study...

A hypertensive man with chronic kidney disease (CKD) secondary to polycystic disease was hospitalized for symptoms related to hypoglycemia. Fasting test elicited symptomatic hypoglycemia after 12 hours, which was associated with inappropriately unsuppressed normal insulin and C-peptide levels. Neither ultrasonography (US) nor magnetic resonance imaging detected any pancreatic tumor. Endoscopic ultrasonography (EUS) showed a small isoechogenic nodule suspect for neuroendocrine tumor in the pancreatic head...

Carpal tunnel syndrome is the most common nerve entrapment syndrome. The majority of cases are due to compression or irritation of the median nerve in the carpal canal. It is diagnosed clinically, often being confirmed by an electromyogram, while ultrasonography criteria have become increasingly useful for the diagnosis. Ultrasonography is better tolerated, less expensive, yet just as effective as other diagnostic methods. It provides a good indication of the severity of the condition and it allows anatomical variants to be discerned...

Gastrointestinal submucosal tumors (SMTs) have been increasingly identified via the use of endoscopic ultrasonography, and removal is often recommended for SMTs that are >2 cm in diameter or symptomatic. Submucosal tunneling endoscopic resection (STER), also known as submucosal endoscopic tumor resection, endoscopic submucosal tunnel dissection or tunneling endoscopic muscularis dissection, is a novel endoscopic technique for treating gastrointestinal SMTs originating from the muscularis propria layer, and has been demonstrated to be effective in the removal of SMTs with a decreased rate of recurrence by clinical studies...
