Artificial pneumoperitoneum is a procedure with which doctors are familiar, particularly in respect to its therapeutic application in pulmonary tuberculosis and chronic diffuse pulmonary emphysema. Diagnostic use of the procedure in lesions of or near the diaphragm is well known to chest physicians and surgeons, yet some general practitioners, surgeons and radiologists have remained hesitant to...

BACKGROUND AND AIM The familial aggregation of Barrett's esophagus, adenocarcinoma of the esophagus, and adenocarcinoma of the gastroesophageal junction, jointly termed familial Barrett's esophagus, may represent a complex genetic trait. The aim of this study was to determine the proportion of patients with these diseases who have familial Barrett's esophagus. METHODS Information on gastroeso...

BACKGROUND/AIMS In recent years, changes in the definition of Barrett's esophagus have resulted in some difficulties in its diagnosis. Very few epidemiological data on Barrett's esophagus and erosive esophagitis in Turkey are available in the literature. The aim of this study was to determine the prevalence of Barrett's esophagus and erosive esophagitis in a tertiary referral center in Turkey. ...

PURPOSE The main purpose was to investigate the differences of the esophageal motion (EM) and the internal target volume (ITV) margins for the esophagus between clinical T1-T3 (cT1-T3) and cT4 cases, using 4-dimensional computed tomography. A secondary purpose was to assess the metastatic lymph nodal motion (NM) and the ITV margins for lymph nodes (LNs) using the datasets of patients with nodal...

Orthotopic models of various types of tumors are widely used in anti-tumor therapeutic experiments in preclinical studies. However, there are few ways to appropriately monitor therapeutic effect in orthotopic tumor models, especially for tumors invisible from the outside. In this study we aimed to establish a non-invasive semi-quantitative bioluminescent imaging method of monitoring an orthotop...

BACKGROUND The distal esophagus harbors a complex bacterial population. We hypothesized that a better understanding of bacterial communities in the esophagus would facilitate understanding of the role of bacteria in esophageal disease. Here, we investigated bacterial composition in the distal esophagus in subjects with a normal esophagus, reflux esophagitis, and Barrett's esophagus. METHODS T...

A 3-cm painless epigastric mass was found on examination in 53-year-old man with abdominal pain and vomiting for the past 6 months. An abdominal computed tomography (CT) scan showed asymmetric thickening of the distal esophagus, and upper endoscopy showed a neoplastic lesion in the distal esophagus (histological examination of the biopsy revealed adenocarcinoma). In the duodenum, we found a sub...

BACKGROUND Left atrioesophageal fistula is a devastating complication of atrial fibrillation ablation. There is no standard approach for avoiding this complication, which is caused by thermal injury during ablation. The objectives of this study were to evaluate the course of the esophagus and the temperature within the esophagus during pulmonary vein antrum isolation (PVAI) and correlate these ...

foreign body ingestion especially in large sizes is seen in children and people with mental illness like mental retardation. the patient is a 19-year-old woman without mental illness. she swallowed one tooth-brush during tooth- brushing, which passed through the esophagus and went in to the stomach and stuck there. after primary endoscopy, was determined that tooth-brush was adult size and its ...
