GASTRIC RESIDUAL VOLUME FACTORS AFTER BOWEL PREPARATION WITH MANNITOL EXPRESS.

Background: Bowel preparation with mannitol is a well-established method in Brazil. However, factors that interfere with the gastric emptying time period are yet to be known. Knowing these factors may favor the examination scheduling logistics and the individualized orientation for each patient.

Underwater endoscopic mucosal resection of serrated adenomas.

Objectives: Serrated polyps, which are considered to be precursors of colorectal carcinoma, include hyperplastic polyps, sessile serrated adenomas and traditional serrated adenomas. With the exception of hyperplastic polyps, all of these lesions must be removed. This study sought to examine whether underwater endoscopic mucosal resection is a safe and effective technique for treating serrated polyps.

Underwater endoscopic resection: an alternative for difficult colorectal polyps.

Background And Aims: Underwater endoscopic resection can be an alternative to standard resection techniques to remove difficult colorectal polyps. This video shows 4 cases of underwater resection of large colorectal polyps.

Methods: Underwater resection consists of complete filling of the lumen through the accessory channel, using an infusion pump followed by snare resection of the polyp.

Pyloric Brunner's gland hamartoma with atypical hyperplasia.

Brunner's gland hamartoma (BGH) is an extremely rare benign digestive tumor, generally located in the duodenal bulb. We report the case of a 51-year-old asymptomatic man with a large pedunculated BGH arising from the pylorus. It was successfully removed by endoscopic resection.
