However, several technical problems during viscerotomy result in considerable delay or procedure failure.
Post-operatively, animal was observed for 2 weeks but it was immediately sacrifised if the creation of viscerotomy had failed.
Viscerotomy was achieved in (17) consecutive cases by 'pre-dilating' the site of initial puncture.
Here, viscerotomy was created by maximum distension of CRE balloon dilator with normal saline.
Spontaneous closure of viscerotomy obstructed re-insertion of endoscope in 3 animals.
We believe that there are several technical issues which determine the outcome of procedure for viscerotomy. Unusual laxity of the gastric mucosa seems to be one of the most important reasons in this regard.
After transgressing the stomach wall with CRE balloons, we dilated separately the gastric and peritoneal ends of viscerotomy in order to straighten the intramural tract.
