[Unusual Ulcer Bleeding in the Stomach].

Emergency upper gastrointestinal endoscopy in a 45 years old man with a complicated medical history obtained a small ulcer in the gastric corpus bedded in a round impression of 4 cm in diameter and no active bleeding during investigation. We decided to perform an immediate angio-CT-examination of thorax and abdomen. Gastric ulcer and impression were induced by a partially thrombosed aneurysm of the splenic artery.

Acute sedation-associated complications in GI endoscopy (ProSed 2 Study): results from the prospective multicentre electronic registry of sedation-associated complications.

Objectives: Sedation has been established for GI endoscopic procedures in most countries, but it is also associated with an added risk of complications. Reported complication rates are variable due to different study methodologies and often limited sample size.

Designs: Acute sedation-associated complications were prospectively recorded in an electronic endoscopy documentation in 39 study centres between December 2011 and August 2014 (median inclusion period 24 months).

Palliative Endoscopic Therapy of Esophageal Cancer.

To reduce pain, water infusion instead of traditional air insufflation during the insertion phase of the colonoscopy has been proposed, thereby improving patients' acceptance of the procedure.
