We present a new case of gastric ESD (antrum) of a lesion with morphology IIa (Classification of Paris) made entirely with Flushknife BT 2.0. The Olympus ESG-300 electrosurgical unit with the configuration of Dr. Rosón (Hospital Quirón, Málaga) has been used. We have improved the procedure time. In this case, only 35 minutes.
We present a new case of ESD in sigma of a lesion with morphology Is (3 cm) (Classification of Paris) made completely with Dualknife J 2.0. The Olympus ESG-300 electrosurgical unit with the configuration of Dr. Rosón (Hospital Quirón, Málaga) has been used. We have improved the procedure time. In this case, only 40 minutes.
A hybrid resection (Hybrid-ESD) of a 25 mm hair lesion with Is morphology in low rectum is performed. Dual Knife J of 1.5 mm has been used.
ESD performed by Dr. J. Guilarte at the Hospital de Baza of a lesion with non-homogenous LST-G morphology of 65 x 45 mm of rectal location. The tunneling technique has been used. The resection was complete (R0). Congratulations to Dr. Guilarte for the work done. Colorectal ESD is already a reality at its center.
An ESD of a lesion with IIa + IIb morphology in the sigmoid colon is exposed. This is our DSE number 11 in the hospital in Poniente. A 1.5 mm BT flush-knife and coagrasper for hemostasis has been used as a hydrodissector. Demirex has been used as a submucosa injection solution (excellent master formula of our friend J. Antonio Morales Molina from the Pharmacy service of the Poniente Hospital). Many thanks to Dr. Katsumi Yamamoto (my dear Japanese friend and ESD world expert) for his good advice in this difficult learning curve of the ESD as well as my good friends, Dr. Rosón (an Andalusian and Spanish expert of the ESD), Dr. Guilarte (friend for 24 years and excellent endoscopist) and of course the group of the «DSE polygonera» (a large endoscopic family).
Hybrid ESD of a lesion with morphology IIa in the gastric body. Flushknife BT 2 mm, Coagrasper and Resolution 360º clip has been used. The histology of the lesion showed the existence of an intramucosal carcinoma.  
ESD is performed on a 2 cm lesion with Is morphology (Paris classification) in the sigmoid colon. Flush-knife 1.5 mm and IT-Nano have been used. Submucosal fibrosis has made dissection difficult
A big cecal lesion (6 x 4 cm) is resected by ESD. The case has been difficult due to poor maneuverability and bleeding during the procedure. At the end of the dissection, it was necessary to change the colonoscope and cap. A standard colonoscope with a distal diameter of 12 mm and a working channel of 3.7 mm has been used. We also had to change to a straight hood to improve visibility. Thanks to Dr. Rosón to help me in this case.
