Direct endoscopic placement of percutaneous endoscopic gastrostomies with jejunal extension tubes (PEG-J) using ultra-thin endoscopes - long-term outcomes from a U.S. tertiary referral center.

Introduction: Several techniques for PEG-J tube placement have been described, commonly requiring fluoroscopic guidance and/or fixation of the jejunostomy tube (J-tube) into the small intestine. We describe a modified technique for placing jejunostomy tubes under direct visualization through a PEG with the use of ultra-thin endoscopes and steel guidewire.

Methods: A retrospective study at a single tertiary academic center evaluating patients who underwent PEG-J placement between 2010 and 2020.

Impact of COVID-19 on gastroenterology fellowship training: a multicenter analysis of endoscopy volumes.

The COVID-19 pandemic has had a profound impact on gastroenterology training programs. We aimed to objectively evaluate procedural training volume and impact of COVID-19 on gastroenterology fellowship programs in the United States. This was a retrospective, multicenter study.

Modified Endoscopic Ultrasound Needle to Obtain Histological Core Tissue Samples: A Retrospective Analysis.

Background/aims: Endoscopic ultrasound (EUS)-guided fine-needle aspiration is very effective for providing specimens for cytological evaluation. However, the ability to provide sufficient tissue for histological evaluation has been challenging due to the technical limitations of dedicated core biopsy needles. Recently, a modified EUS needle has been introduced to obtain tissue core samples for histological analysis.

The treatment of cholangiocarcinoma: a hepatologist's perspective.

Cholangiocarcinoma (CCA) is a rare but lethal adenocarcinoma with cholangiocyte differentiation that arises within the biliary tree at variable locations. Curative options are available in the form of surgical resection and/or liver transplantation (LT) in early stage CCA; however, these are offered to a small fraction of patients as they are usually asymptomatic and remain undiagnosed. Primary sclerosing cholangitis (PSC) is a well-known risk factor of CCA, and cirrhosis, viral hepatitis, and metabolic syndrome are recently identified as risk factors of CCA.

Hepatic artery Doppler indices in children with extra hepatic portal vein obstruction.

Unlabelled: Doppler measurement provides information on the hemodynamics in the hepatic artery and the portal venous system.

Aim: To study the hepatic artery hemodynamics in children with extra hepatic portal vein obstruction.

Materials And Methods: Hepatic artery indices were studied using Doppler indices in 15 children (<12 years) with extra hepatic portal hypertension (EHPVO) and obliterated esophageal varices.

Problems in diagnosing lymphoma of the pancreas with computed tomography. A case report.

Primary lymphoma of the pancreas is a rare form of extranodal lymphoma accounting for less than 0.5% of pancreatic tumors. Percutaneous fine-needle aspiration of the pancreas with histopathological examination and immunohistochemical assay confirm the diagnosis.
