Endoscopic removal of foreign bodies using a newly developed extractor.

A newly developed extractor for the endoscopic removal of foreign bodies has already been used with success. It can be rotated through 360 degrees, so that foreign bodies can be grasped from any angle. Capture and extraction of the foreign body is accomplished with a band-like snare, the inside surface of which is provided with tiny "studs". With the aid of this extractor, foreign bodies can be captured and removed quickly, reliably, and without risk to the patient.

[Mechanical destruction of common bile duct calculi].

After endoscopic papillotomy freedom from stone in the choledochal duct can be achieved in about 90% of cases. Either there is a spontaneous passage of concrements or they can be extracted with a basket. But in 10% the stones are so large or are so disproportionate to the size of the distal choledochal duct, that they cannot be removed by conventional means. Mechanical lithotripsy is an easy and simply learned alternative to electro-hydraulic lithotripsy or intraductal gall-stone dissolution for non-surgical removal of large concrements. So far the method has been successful in 18 of 20 patients. Average size of the bile-duct concrements was 27.3 mm with a mean distal choledochal diameter of 10.4 mm. In four patients the stone fragments were passed spontaneously, in 14 they were removed either with the lithotripter itself or the basket. Mechanical lithotripsy is thus an important addition to the non-surgical treatment of gall-stones.

Mechanical lithotripsy through the intact papilla of vater.

The indications for endoscopic papillotomy are clearly defined. When only the normal risk presents, our working group favours an age limit of 50 years, below which the papilla should, as far as possible, be preserved. In the present case report, a possibility is described for effecting an endoscopic extraction of bile duct concrements through a completely intact papilla. It is thus apparent that, in certain cases, mechanical lithotripsy can also be employed to smash ductal stones through the intact papilla.

Clinical application of a new mechanical lithotripter for smashing common bile duct stones.

After endoscopic papillotomy, the extraction of large stones is often very difficult. In numerous cases, it proves impossible to remove large concretions using conventional methods. On account of technical problems, electro-hydraulic lithotripsy was unable to fulfill all the hopes placed in it. A possible alternative method is that of mechanical lithotripsy. Initial clinical experience gained in 8 patients with large stones in the common bile duct, has shown that, with the aid of the technically simple procedure, it is possible to extract such large concretions, too.

A new catheter for endoscopic manometry of Oddi's sphincter.

With a newly designed manometry catheter and a modified pull-through maneuver a high presure zone can reproducibly be recorded between the duodenum and the pancreato-biliary tree corresponding to Oddi's sphincter. Catheter marking allows in addition calculation of the length of this zone. Since the sealed end of the catheter remains during pressure recording within the ductal system repeated push-and-pull maneuvres can be performed through the sphincter area.
