Delayed Retroperitoneal Hemorrhage as a Complication of Large-volume Paracentesis.

Large-volume paracentesis (LVP) consists of the removal of more than four liters of ascitic fluid. This procedure can cause complications such as hemorrhage, infection, bowel perforation, circulatory failure, or ascitic fluid leakage. The main presentation of paracentesis-induced hemorrhage is abdominal wall hematoma.

Predictors of incomplete optical colonoscopy using computed tomographic colonography.

Background/aims: Optical colonoscopy (OC) is the primary modality for investigation of colonic pathology. Although there is data on demographic factors for incomplete OC, paucity of data exists for anatomic variables that are associated with an incomplete OC. These anatomic variables can be visualized using computed tomographic colonography (CTC).

Iatrogenic pharyngoesophageal perforations treated with fully covered self-expandable metallic stents (with video).

Background: Iatrogenic pharyngoesophageal perforations are a rare but serious complication of endoscopy. Surgical and non-surgical approaches have been reported but result in a significant morbidity and extended hospital stay. Therefore, an unmet need exists for an alternative management technique.
