1.endoscopic basket retrieval of stones
An endoscope of tiny diameter is used to locate the stone within the duct and a wire basket removes the cause of obstruction. This technique applies to calculi measuring up to 4-5mm.
2.endoscopic haldheld laser stone breaking of stones
A laser probe is guided through the endoscope channel and fragments the bigger stones 5-8mm in order for the smaller particles to be grasped with a forcep or retrieved with a basket.
3.endoscopically assisted surgical removal of stones
Occasionally stones are too big to fragment or retrieve or they are located in unaccesible areas within the ductal system of the glands that makes combined open and endoscopic approach the alternative to radical surgery.
1.Endoscopically assisted dilatation/sialoplasty
Strictures can be dilated with special salivary probes, the active passage of endoscope of gradually increasing size and balloons .
2.Radiologically Guided dilatation/sialoplasty
under radiological control a balloon is used to dilate/stretch the narrowed duct.
