Colonoscopy of syncronic polyps and colon cancer of the transverse.

This is a 57 year-old Male, who has rectal bleeding since 4 months. Barium enema practiced in a public hospital was negative.

At colonoscopy there are three polyps two of them are presented in this endoscopic sequence, and one is quite small of the transverse colon, three underwent polypectomy.

In the transverse colon there are a colon adenocarcinoma which obstructs the lumen by 98% it was unable to advance the colonoscope.

In this video clip and the image shows a synchronous polyp of the sigmoid.

check up.
A 77 year-old female, came to our unit due to epigastric
pain. An upper endoscopy revealed two pre-piloric ulcers
and reflux esophagitis grade III.
after the upper endoscopy was performed We
recommended a full colonoscopy as a medical check up
finding this mass.

Endoscopic Resection of Rectal Cancer

A patient of 79 year-old male, who had been with enterorragia of three months of evolution, 7 years previous we had performed an upper endoscopy and was recommended a colonoscopy but never return, at that same time we performed rubber band ligation for internal hemorrhoids

Upon rectal palpation a small mass with cancer texture is palpated, which is inserted into the pectine line and was prepared for colonoscopy the next day this endoscopic resection is performed and without previous biospies.
