Multiple lymphomatous polyposis: rectal prolapse as an atypical presentation of the disease.

Multiple lymphomatous polyposis is a rare entity that can involve different types of both B-cell and T-cell lymphomas, including mantle cell lymphoma. A 57-year-old male patient is presented with prolapse of the rectal canal associated with data of lower digestive tract bleeding. A colonoscopy and subsequent upper endoscopy were performed with findings compatible with lymphomatous polyposis.

Accuracy of ASGE criteria for the prediction of choledocholithiasis.

Background/aims: Few studies have validated the performance of guidelines for the prediction of choledocholithiasis (CL). Our objective was to prospectively assess the accuracy of the American Society for Gastrointestinal Endoscopy (ASGE) guidelines for the identification of CL.

Methods: A two-year prospective evaluation of patients with suspected CL was performed.

Predictors of in-hospital mortality in patients with non-variceal upper gastrointestinal bleeding.

Objective: to determine the independent predictors of in-hospital death of Hispanic patients with nonvariceal upper gastrointestinal bleeding (NVUGB).

Experimental Design: prospective and observational trial.

Patients: in a period between 2000 and 2009, all patients with NVUGB admitted to our hospital were studied.

Model for end stage of liver disease (MELD) is better than the Child-Pugh score for predicting in-hospital mortality related to esophageal variceal bleeding.

Aim: The Child Pugh and MELD are good methods for predicting mortality in patients with chronic liver disease. We investigated their performance as risk factors for failure to control bleeding, in-hospital overall mortality and death related to esophageal variceal bleeding episodes.

Methods: From a previous collected database, 212 cirrhotic patients with variceal bleeding admitted to our hospital were studied.

[Ultrasonic endoscopy].

Ultrasonic endoscopy or endosonography is a diagnostic tool that currently becomes one of the most citated innovations to resolve difficult problems in gastroenterology. The article reviews the currently accepted indications by the American Society of Gastrointestinal Endoscopy.
