Endosonographic radial tumor thickness after neoadjuvant chemoradiation therapy to predict response and survival in patients with locally advanced esophageal cancer: a prospective multicenter phase ll study by the Swiss Group for Clinical Cancer Research (SAKK 75/02).

Background: EUS response assessment in patients with locally advanced esophageal cancer undergoing neoadjuvant chemoradiation therapy (CRT) is limited by disintegration of the involved anatomic structures.

Objective: Predictive and prognostic values of a prospectively defined maximum tumor thickness (MTT).

Design: Prospective open-label phase ll study (SAKK 75/02).

Endoscopic ultrasound-guided drainage of abdominal abscesses and infected necrosis.

Traditionally abdominal abscesses have been treated with either surgical or radiologically guided percutaneous drainage. Surgical drainage procedures may be associated with considerable morbidity and mortality, and serious complications may also arise from percutaneous drainage. Endoscopic ultrasound (EUS)-guided drainage of well-demarcated abdominal abscesses, with adjunctive endoscopic debridement in the presence of solid necrotic debris, has been shown to be feasible and safe.

Detection and endoscopic therapy of early esophageal adenocarcinoma.

Purpose Of Review: This review summarizes recent progress on endoscopic diagnosis and treatment of esophageal high-grade intraepithelial neoplasia and early adenocarcinoma and critically analyzes the literature in the context of preexisting scientific data.

Recent Findings: Narrow band imaging and computed virtual chromoendoscopy enhanced visualization of the mucosal morphology. The type of mucosal and capillary patterns seen on narrow band imaging predicted the presence of specialized intestinal metaplasia, high-grade intraepithelial neoplasia and early adenocarcinoma.

Application of bleeding prophylactic criteria (NICE) in patients with acute gastrointestinal bleeding. A Swiss prospective study.

Multiple treatment guidelines for nonsteroidal anti-inflammatory drugs (NSAIDs) suggest that patients with one or more risk factors for NSAID-related ulcer complications should be prescribed preventive strategies such as acid-suppressive drugs, misoprostol or COX-2-specific inhibitors to reduce their risk of serious ulcer complications. However data are lacking as to how many patients have been on preventive measures in accordance to the National Institute for Clinical Excellence (NICE) criteria in our population. We therefore evaluated the extent to which patients with acute gastrointestinal bleeding have been under ulcer-preventive strategies at the time of hospital entry.

[Epidemiology of gastrointestinal bleeding in the elderly].

The epidemiological pattern of gastrointestinal bleed in western countries has been steadily changing over the last few years given the rising prevalence of an elderly population. In a one year prospective study at a referral hospital in Zurich, Switzerland, hospitalised patients were investigated with regards to the epidemiology of gastrointestinal (GI) bleeding. Of 7406 hospitalisations, a total number of 224 GI bleeds were registered (53% women, mean age 71 +/- 16, 63% with relevant co morbidities).
