[Peroral and transhepatic cholangioscopy].

Cholangioscopy is possible via the peroral or the transhepatic route. Cholangioscopy is of diagnostic value in tumour strictures and stenoses of the common bile duct. More important than diagnostic cholangioscopy is therapeutic cholangioscopy: with the technique of intracorporeal shockwave lithotripsy nearly all difficult CBD-stones may be successfully treated. 17 patients with 40 CBD-stones were managed in mother-babytechnique in applicating intraductal shockwaves under direct visual control (electrohydraulic principle). Mechanical lithotripsy during ERCP had formerly failed in all patients. In 6 patients transhepatic cholangioscopy with intracorporeal shockwave lithotripsy was successfully performed. Patients had an operated stomach, so conventional ERCP with lithotripsy was not possible. 18 stones could be treated. As a total 23 patients with 58 CBD-Stones underwent cholangioscopy (median stone diameter 20 mm) with intracorporeal shockwave lithotripsy. Complete stone clearance was achieved in all cases, no serious complication occurred.

[Percutaneous transhepatic cholangioscopy as a single-step technique].

The PTCS is a method for diagnostic and therapeutic purpose in patients with common bile duct diseases not suitable for transpapillary approach. The present paper describes a technique which shortens the usual time of treatment and reduces injury. Lithotripsy of common bile duct stones, endoscopic controlled biopsy, introduction and removal of bile duct endoprosthesis as well as percutaneous papillotomy is possible.

Single-step percutaneous transhepatic cholecystoscopy.

A 58-year-old female patient with several concrements in the gallbladder submitted herself to pump-controlled percutaneous transhepatic chemolitholysis with methyl-tert-butyl-ether (MTBE). Shortly before the treatment terminated a calcified residual concrement caused an acute blockage of the cystic duct. After opening the puncture track with a bougie, followed by endoscopic lithotripsy, the cystic duct was made passable again.

[The effect pf antacids on the tissue histamine and prostaglandin (PGE2) content of the gastric mucosa].

Stimulation tests (pentagastrin) induced significant changes in tissue histamine levels in the gastric mucosa within 30 minutes. Acid secretion and a decrease of histamine after application of antacids containing calcium could not be observed in our study; neither was application of antacids over a period of eight days followed by a change in gastric mucosal tissue histamine concentrations. Patients under non-steroidal antiphlogistic medication showed diminished histamine levels. Administration of antacids did not produce changes in histamine levels, but induced a rise of PGE2 levels in the fundal and corpus area of the stomach. This may be due to a cytoprotective effect of antacids containing calcium on the gastric mucosa.
