Review Case Reports
Uvular necrosis after upper endoscopy: a case report and review of the literature.
Uvular necrosis after endotracheal intubation or upper endoscopy is rare. We report here on a case of uvular necrosis and ulceration after endoscopy. The combination of ulceration and necrosis suggests uvular ischemia during endoscopy. ⋯ In all reported cases, and in the present case as well, the uvula healed and the symptoms resolved within 2 weeks (5 - 14 days) after the procedure. The uvula regained its normal appearance. Overall, these patients should have a good clinical outcome.

Comparative Study
Differences in the diagnostic yield of upper gastrointestinal endoscopy in dyspeptic patients receiving proton-pump inhibitors and H2-receptor antagonists.
Patients attending for diagnostic oesophagogastroduodenoscopy (OGD) for dyspeptic symptoms are often receiving acid-suppression therapy that has not been discontinued prior to endoscopy, and this may reduce the diagnostic yield of endoscopy. The aim of this study was to compare the diagnostic yield of OGD in uncomplicated dyspepsia in patients receiving no medication, those receiving acid-suppression therapy, and those receiving nonsteroidal anti-inflammatory drugs (NSAIDs) at the time of endoscopy. ⋯ The widespread use of acid suppression in the treatment of simple dyspepsia prior to endoscopy leads to a reduction in the endoscopic recognition of mucosal lesions caused by acid-peptic disease, but not to a high healing rate for these lesions, and it may mask malignancy.

Excessive blood covering the examination field is a frequent cause of diagnostic failure in emergency endoscopy for acute upper gastrointestinal bleeding. The implications and outcome in these patients have not been well described. ⋯ In acute nonvariceal upper gastrointestinal bleeding, diagnostic failure is associated with higher morbidity and mortality. The data from this study emphasize the importance of good preparation before the procedure and adequate removal of blood during emergency endoscopy procedures.
