Traditionally, the only options available for removing large lesions in the GI tract have been either Endoscopic piece-meal resection or surgery.
Whilst often successful, piece-meal resection dramatically reduces the certainty with which the pathology of invasion can be determined - often having a detrimental effect on the patient care and risk of recurrence.
KeyMed is therefore pleased to announce the introduction of the complete range of Olympus ESD devices. For the first time, complete en-block resection of large lesions within the GI tract is now possible endoscopically.
One method of ESD is described below:
|
 |
Once identified, the lesion is clearly marked proud of its circumference to aid in identification during the ESD procedure. |
 |
The lesion is raised by injecting a haemostatic solution (such as epinephrine) into the submucosal layer. This creates a space between the muscularis and the mucosa reducing the risk of perforation. |
 |
The submucosa is accessed by means of the HotBite ESD Forceps. |
 |
The access ports made by the HotBite ESD Forceps allow entry for the IT Knife2 into the submucosa and then diathermy is used to join the ports together. |
 |
Once the circumference of the lesion has been disected from the surrounding mucosa, the disection boundaries of the lesion will be clearly identifiable. |
 |
Subject to the size of the lesion being disected, removal is now completed using a standard SnareMaster snare and PolyGrap grasper. |
