A 70 years old male with previous rectal cancer and anastomosis T-T 9 cm from dentate line. A LST-NG lesion 20 mm size, situated in the posterior rectal wall, close to dentate line, was found. This was the first case performed in Baza Hospital by Dr. Julio Guilarte, supervised by Dr. Katsumi Yamamoto (JCHO Hospital, Osaka) and suported by Dr. F. Gallego, Dr. PJ. Rosón and Dr. FM.

A 45-year-old patient with a family history of CRC (father diagnosed with ascending colon cancer at 64 years of age, dying at 68 years of age). It was found in a family screening colonoscopy of an ascending colon lesion of 18 mm with morphology LST-G / IIa + IIc. The lesion was resected with a hybrid technique due to the poor maneuverability of the colonoscope and severe submucosal fibrosis.
