The ectopic liver (or choristoma) is a rare condition found during autopsy or abdominal exploration for various indications. The authors report two cases of ectopic liver found during laparoscopic cholecystectomy for acute cholestytis. The ectopic liver tissue has been reported to develop in several sites as thoracic cavity, gastrohepatic ligament, adrenal glands, pancreas, esophagus and, above...

Diseases affecting pulmonary mechanics often result in changes to the coordination of swallow and breathing. We hypothesize that during times of increased intrathoracic pressure, swallow suppresses ongoing expiratory drive to ensure bolus transport through the esophagus. To this end, we sought to determine the effects of swallow on abdominal electromyographic (EMG) activity during expiratory th...

Esophageal duplication cysts are congenital anomalies of the foregut that are rarely found in the abdomen. An accurate preoperative diagnosis is not always possible, so the definitive diagnosis can be made by histologic examination of the surgical specimen. We experienced a case of Intra-abdominal esophageal duplication cyst in a 52-year-old female, who initially presented with an esophageal su...

BACKGROUND The aim of this observational study is to analyze the results of patients with large hiatal hernia and upside-down stomach after surgical closure with a biological mesh (Permacol(®), Covidien, Neustadt an der Donau, Germany). Biological mesh is used to prevent long-term detrimental effects of artificial meshes and to reduce recurrence rates. METHODS A total of 13 patients with a la...

Acute esophageal necrosis (AEN), also called "black esophagus," is a condition characterized by circumferential necrosis of the esophagus with universal distal involvement and variable proximal extension with clear demarcation at the gastroesophageal junction. It is an unusual cause of upper gastrointestinal bleeding and is recognized with distinct and striking mucosal findings on endoscopy. Th...

RATIONAL Infective endocarditis caused by a foreign body of the upper digestive tract is rare. We report a rare case of Granulicatella adiacens and Candida albicans coinfection acute endocarditis combined with systematic embolization caused by a fish bone from the esophagus penetrating into the left atrium. PATIENT CONCERN A 42-year-old woman was admitted to our hospital because of fever, abd...

A 77-year-old man was admitted for abdominal pain. He had no anemia or abnormal physical findings. We diagnosed the patient with chololithic pancreatitis, and performed endoscopic retrograde cholangiopancreatography. We began to insert a side-viewing duodenoscope, but had difficulty passing it through the left pyriform sinus. When we switched to a forward-viewing duodenoscope, we found that mem...

BACKGROUND Spontaneous rupture of the esophagus (Boerhaave's syndrome) is a rare, well-defined clinical syndrome caused by a longitudinal perforation of the esophagus. It is a life-threatening condition that necessitates rapid diagnosis and treatment. Patients typically present acutely with a history of vomiting followed by chest or abdominal pain. However, the diagnosis may be difficult or mis...

Primary intestinal T-cell lymphoma is a rare disease entity, which is approximately 10% to 25% of intestinal lymphomas, and most of the lymphomas occur in the small intestine. We report here a case of a 56-year-old woman who has been suffering from chronic diarrhea and weight loss for 6 months. Abdominal CT scan and small bowel series showed diffuse wall thickening of the small bowel. Gastrosco...

A 60-year-old man presented to our hospital with a chief complaint of dysphagia. Barium swallow examination showed a filling defect in the upper thoracic esophagus, and gastrointestinal endoscopy revealed a polypoid tumor, 4 cm in size, accompanied by an ulcerative lesion at the top of the tumor, which indicated carcinosarcoma or squamous cell carcinoma (Fig. 1). Contrast-enhanced computed tomo...
