Background: gastric cancer (GC) is a gastrointestinal (GI) neoplasia which often complicates with GI bleeding. It is uncertain if bleeding worsens mortality in this group of patients.
Aims: to compare 30- and 90-day mortality in patients with unresectable GC (uGC) and tumor bleeding versus patients with the same neoplasia without bleeding.
Introduction: endoscopic evaluation of the ampulla of Vater (AV), although routinely recommended, is not always possible due to its anatomic configuration, which can hide it from the visual field of the forward-viewing endoscope. Cap-assisted forward-viewing endoscopy has been proposed as a useful alternative to facilitate the examination of this structure.
Objectives: to assess the efficacy of cap-assisted forward-viewing endoscopy for the complete evaluation of the AV.
Introduction: Benign strictures are frequent complications following colorectal surgery, with an incidence of up to 20%. Endoscopic treatment is safe and effective but there is not enough evidence for establishing stricture management at that anatomic level.
Aim: To determine the risk factors associated with the development of stricture in patients with colorectal cancer and describe endoscopic treatment in those patients.
Introduction And Objectives: Self-expanding metallic stents (SEMS) are the ideal treatment for malignant gastric outlet obstruction (MGOO) in patients with a short life expectancy, but stent dysfunction is frequent. The primary aim of our study was to identify the predictive factors of SEMS dysfunction in MGOO and the secondary aim was to determine the technical success, clinical success, and nutritional impact after SEMS placement.
Material And Methods: A retrospective, longitudinal study was conducted at the gastrointestinal endoscopy department of the Instituto Nacional de Cancerología in Mexico City.
