colonoscopy
A LST G Lesion
The following video presents a characteristic image of a LST-G (laterally spreading tumor - granular) lesion located in the colon.
B Piecemeal Resection
The following video presents a footage of a piecemeal snare resection of a polyp located in the colon.
D Completion EMR
The video presented above shows an EMR (endoscopic mucosal resection) performed after snare resection of the polyp in order to remove all lesion cells and prevent recurrence of the polyp.
F Submucosal Chromoendoscopy
Changes of mucous membrane cells are not always visible in the normal endoscopy. To detect abnormal cells a submucosal chromoendoscopy, as presented above, is performed.
EMR Scar Clip
The following video shows clipping of a lesion created by scar resection. Clip closure is performed to bring the edges of the wound together to ease the healing end to prevent complications, such as delayed...
EMR Scar Injection
Injections are performed to form a superficial blebs and to lift the tissue we want to remove to make the resection easier. The following video presents a technique for an EMR scar injection.
EMR Scar BX
The following video shows a biopsy excision of a tissue residual after snare resection. It is always vital to remove all of the lesion, so, if a snare resection isn't possible to perform, different techniques...
EMR Scar Resection
This video shows a snare resection of a scar created after previous EMR. This procedure is done if the recurrence of the lesion is suspected. The consequtive steps are described during the clip.
C Hemostasis
The following video presents how to manage the bleeding created after endoscopic mucosal resection (EMR) of the lesion located in the colon.
E APC
The video presented above shows an argon plasma coagulation (APC) of the base and edges of the lesion created after polyp resection. The APC is used to prevent delayed bleeding and to prevent the recurrence...

Colonoscopy - Rectum - Radiation Telangectasia...
This video shows a radiation telangectasia with an ulcer of the rectum. One should be careful if cautery of the rectum with APC is undertaken in such cases with an ulcer (indicative of underlying ischemia)...
Colonoscopy - Rectum - APC of Bleeding Angioectasia
This video shows a management of radiation telangiectasia after pelvic radiation. Active bleeding was seen in the rectum adjacent to which was a very subtle angioectasia which was treated with argon plasma...
Colonoscopy Goes Awry - Cecal EMR Bleed - clip...
This video shows clip closure after endoscopic mucosal resection (EMR). EMR is usually performed with a polypectomy snare after the lesion has been lifted with a submucosal fluid injection. On the end...
