Exocrine pancreatic insufficiency and graft-versus-host disease.

We present the case of a 59-year-old man with acute myeloid leukemia treated with allogeneic hematopoietic stem cell transplantation (allo-HSCT). Two years later, he consulted for diarrhea and steatorrhea of 2-3 months of evolution with significant weight loss. Stool cultures and study of parasites were negative.

Endoscopy-Related Bleeding and Thromboembolic Events in Patients on Direct Oral Anticoagulants or Vitamin K Antagonists.

Background & Aims: Few prospective studies have assessed the safety of direct oral anticoagulants (DOACs) in elective endoscopy. Our primary aim was to compare the risks of endoscopy-related gastrointestinal bleeding and thromboembolic events in patients on DOACs or vitamin K antagonists (VKAs) in this setting. Secondarily, we examined the impact of the timing of anticoagulant resumption on the risk of delayed bleeding in high-risk therapeutic procedures.

[Acute liver ischaemia after gastro-oesophageal variceal bleeding].

Introduction: Variceal upper gastrointestinal bleeding (UGIB) can trigger acute hypoxic hepatitis (AHH). The aim of this study was to analyse the incidence, associated risk factors and mortality of AHH after variceal UGIB.

Patients And Methods: Retrospective study of cirrhotic patients with variceal UGIB, classified into 2 groups according to the development of AHH.

[Autoimmune pancreatitis].

Autoimmune pancreatitis is a benign fibroinflammatory disease of the pancreas of probable autoimmune origin, which includes 2 different phenotypes: type 1 (lymphoplasmacytic sclerosing pancreatitis) and type 2 (idiopathic duct-centric pancreatitis). Its clinical presentation as obstructive jaundice in patients with a pancreatic mass is common and therefore it must be included in the differential diagnosis of pancreatic neoplasia. Many diagnostic criteria have been described throughout history.

[Acute hypertrygliceridemic pancreatitis].

Acute hypertriglyceridemic pancreatitis is the third cause of acute pancreatitis in the Western population. There is usually an underlying alteration in lipid metabolism and a secondary factor. Clinical presentation is similar to that of pancreatitis of other etiologies, but the course of acute hypertriglyceridemic pancreatitis seems to be worse and more recurrent.

[An exceptional cause of acute hepatitis in an adult: parvovirus B19].

There are multiple causes of hepatitis. The most frequent etiologies are viral, usually hepatitis A, B and C viruses. However, other, non-hepatotropic viruses can cause this disease, including parvovirus B19.

[Octreotide treatment for postoperative chylous ascites in an adult].

Chylous ascites is infequent after abdominal surgery. We describe the case of a 43-year-old man with portal cavernomatosis who underwent surgery to insert a splenorenal shunt, which was not placed due to the absence of signs of portal hypertension. On postoperative day 20, the patient developed abdominal distension and mild dyspnea and was diagnosed with chylous ascites, which was related to the surgery.
