The "swinging" squamocolumnar junction in esophagocardiac achalasia.
A 45-year-old woman was referred for evaluation of longstanding dysphagia to both solids and fluids, and progressive regurgitation over the past 10 years. Besides glycogenic acanthosis, upper gastrointestinal endoscopy was suggestive of esophageal dilation with a hypomotile contraction pattern. During careful observation with air insufflation, the narrowed esophagogastric junction failed to rel...
متن کاملStudies of acid exposure immediately above the gastro-oesophageal squamocolumnar junction: evidence of short segment reflux.
BACKGROUND AND AIMS Oesophageal pH is conventionally recorded from a point 5 cm above the lower oesophageal sphincter. However, the mucosal changes of reflux oesophagitis and intestinal metaplasia tend to affect the segment of oesophagus distal to this and close to the squamocolumnar junction. This study set out to investigate oesophageal acid exposure of squamous mucosa close to the squamocolu...
متن کاملA discrete population of squamocolumnar junction cells implicated in the pathogenesis of cervical cancer.
Infection by carcinogenic human papillomaviruses (HPV) results in precancers [cervical intraepithelial neoplasia (CIN)] and cancers near the ectoendocervical squamocolumnar (SC) junction of the cervix. However, the specific cells targeted by HPV have not been identified and the cellular origin of cervical cancer remains elusive. In this study, we uncovered a discrete population of SC junctional...
متن کاملIntestinal metaplasia at the squamocolumnar junction in patients attending for diagnostic gastroscopy.
BACKGROUND The incidence of adenocarcinoma of the oesophagus and gastric cardia is increasing rapidly. Barrett's oesophagus is the major risk factor. Intestinal metaplasia at the squamocolumnar junction in the absence of Barrett's oesophagus is common but its relation to adenocarcinoma and gastro-oesophageal reflux disease is unclear. AIMS To study the prevalence and clinical, endoscopic, and...
متن کاملIdentifying intestinal metaplasia at the squamocolumnar junction by using optical coherence tomography.
BACKGROUND Optical coherence tomography (OCT) is an optical imaging method that produces high-resolution cross-sectional images of the esophagus. The accuracy of OCT for differentiating tissue types at the squamocolumnar junction (SCJ) has not been established. OBJECTIVE The purpose of this study was to identify and validate OCT image criteria for distinguishing metaplastic from nonmetaplasti...
