BACKGROUND Previous studies that showed an association between smoking and adenocarcinomas of the esophagus and esophagogastric junction were limited in their ability to assess differences by tumor site, sex, dose-response, and duration of cigarette smoking cessation. METHODS We used primary data from 10 population-based case-control studies and two cohort studies from the Barrett's Esophagus...
Here, we report a case with intraluminal membrane (web) located in the lower esophagus causing complete obstruction. Esophagogram revealed complete obstruction near the esophagogastric junction. Surgical excision of the esophageal membrane was performed. To our knowledge, only a few cases with membranous esophageal atresia have been reported. It must be remembered in neonates who cannot tolerat...
BACKGROUND COX-2 expression induces carcinogenesis and is thought to be an adverse prognostic factor in gastric carcinomas while the prognostic value of DNA mismatch repair (MMR) is still controversial. Concerning adenocarcinomas of the esophagogastric junction, no comprehensive data regarding either factors are available as of yet. OBJECTIVE We assessed expression of COX-2, MLH1 and MSH2 in ...

Endoscopic ultrasound (EUS)-guided transmural drainage (EUS-TD) was recently developed and has proven to be a useful alternative approach for various intra-abdominal conditions [1–3]. In this procedure, an intrathoracic passage should be avoided, because it causes severe complications, such as mediastinitis [4, 5]. Unfortunately, however, it is difficult to confirm whether a puncture route can ...
To study the appearance and distribution of the normal mucosa at the gastroduodenal junction in man, 14 specimens of normal mucosa, eight obtained during pylorplasty, and "relatively" normal specimens from the distal stomach and whole duodenum were examined microscopically. Three histologically distinct types of normal duodenal mucosa were found at this junction. These were termed antral type d...
Background Postoperative complications such as failure or disruption of the crura repair and intrathoracic migration of the wrap are the most common anatomic reasons for the failure of Laparoscopic Nissen Fundoplication. The authors hypothesized that ultrastructural illness may be implicated in this recurrence. The aim of this study was to investigate the presence of changes at esophageal hiata...
gastric junction gastrointestinal stromal tumor assisted by laparoscopy after neoadjuvant therapy Gastrointestinal stromal tumors (GISTs) are the most common mesenchymal neoplasms of the digestive tract [1]. Surgery is the only potentially curative therapy. However, some tumors are locally advanced, and therefore R0 resection cannot be guaranteed. In this situation, imatinib can allow organ-pre...
