Spontaneous cystogastric fistula: an accidental discovery.

Pancreatic pseudocysts are very common cystic lesions after any inflammatory process of the pancreas. The majority are asymptomatic and only a small minority present complications or produce compression symptoms. However, this small minority must receive treatment, which depending on the clinical situation must be endoscopic, surgical or interventional radiology.

Endoscopic rescue of a fistulizing biliary plastic stent.

55-year-old male with a history of cholecystectomy complicated by perforation of the common bile duct, contained with placement of a plastic biliary stent. He presented several subsequent episodes of recurrent cholangitis secondary to biliary lithiasis and residual benign stenosis of the common bile duct, resolved with the implantation of plastic biliary prostheses. Finally, given the recurrent episodes of cholangitis, it was agreed to perform a hepaticojejunostomy.

Eagle's syndrome as a cause of oropharyngeal dysphagia.

Eagle's syndrome is a little known entity defined as the elongation of the stylohyoid process and/or calcification of the stylohyoid ligament. It is a rare pathology that due to its presentation and possible complications should be taken into consideration in the differential diagnosis of oropharyngeal dysphagia. We present the case of a patient with Eagle's syndrome as well as essential aspects in the diagnosis and treatment of this entity.

Therapeutic approach of esophageal bezoar due to enteral feed.

Enteral feed bezoars are a rare and difficult to treat complication of enteral feeding. In our case, we report the case of a young man with prolonged admission at the intensive care unit; who requires enteral nutrition. This doesn't run properly after a week; which is why we performed an endoscopy with the finding of an esophageal bezoar that didn't respond to endoscopic treatment at first; being finallay resolved with a second endoscopic therapy after treatment with solvent substances.

A large perforated gastric ulcer due to cocaine use.

Juxtapyloric perforation is one of the most common digestive tract complications associated with cocaine use. We present the case of an habitual user of cocaine who goes to the Emergency Department due to epigastric pain due and intolerance of days of evolution. An endoscopic finding of a large antral ulcer with an ischemic appearance; in which it is not possible to show pylorus.

Recidivant odynophagia secondary to persistent esophageal candidiasis in an immunocompetent patient: the importance of brush cytology.

We present the case of a 53-year-old smoker woman without any relevant medical history who was attended as an outpatient due to several-month persistent odynophagia. An upper gastrointestinal endoscopy was performed, showing white cotton-like plaques throughout the esophagus, suggestive of candidiasis. An esophageal brushing plus biopsy sampling were done, empirically prescribing oral fluconazole for 21 days.

Carcinosarcoma of the extrahepatic bile duct: an unusual cause of obstructive jaundice.

In relation to the article published in this journal by Guzmán describing a case of ampulla of Vater carcinosarcoma, we present a case of extrahepatic bile duct carcinosarcoma. A neoplasm described in different anatomical locations with an exceptional origin in the bile duct.

Biliary bleeding due to a hepatic artery pseudoaneurysm rupture.

Hepatic artery pseudoaneurysm is a rare cause of upper gastrointestinal bleeding. Traumatic etiology is frequent (vascular anastomosis or iatrogenesisia), although it is also related to infectious or inflammatory diseases. We report the case of a 65-year-old patient, with hematemesis due to hepatic artery branch pseudoaneurysm rupture, in the context of infectious endocarditis.

Eosinophilic cholecystitis: an infrequent cause of acute cholecystitis.

Eosinophilic cholecystitis (EC) is a rare disease that is characterised by eosinophilic infiltration of the gallbladder. Its pathogenesis is unknown, although many hypotheses have been made. Clinical and laboratory manifestations do not differ from those of other causes of cholecystitis.
