[Direct cholangiography: endoscopic-retrograde or percutaneous transhepatic? (author's transl)].

Indications, success-rate and disadvantages of endoscopic retrograde (n = 928) and percutaneous transhepatic cholangiography (n approximately 360) at the Surgical and Medical University Clinics of Freiburg/German are discussed. Direct cholegraphy is the method of choice in cases of cholestasis of unknown origin. Endoscopic retrograde procedures usually preceed the percutaneous transhepatic approach. PTC either complementary or decisive when ERCP has failed. Therapeutic possibilities of both methods are not yet totally utilized.

Intrahepatic cystic bile duct dilatations and stone formation: a new case of Caroli's disease.

Caroli's disease is a rare familial anomaly with circumscribed saccular dilatations of enlarged intrahepatic bile ducts coated by regular or pseudopapillomatous epithelium. The disease may be combined with additional malformations of the extrahepatic biliary tract as well as with medullary sponge kidney. Infection and stone formation are frequent complications. Surgery is indicated if the disease is limited to one love which should be resected or if biliary obstruction in diffuse disease necessitates biliodigestive anastomosis. Antibiotics and CDCA-mediation are essential for symptomatic therapy. We analysed the findings in 40 cases including one own observation.

[Problems in congenital choledochus cysts].

Congenital choledochal cysts are classified into three types (type A = cystic dilatation, type B = diverticula, Type C = choledochocele). In addition, all cases of types A and B may have anomalies of the pancreaticobiliary duct system. In type I the pancreatic duct enters the common duct and in type II the common duct enters the pancreatic duct. These anomalies are considered etiological factors in the development of choledochal cysts and are important for prognosis and therapy. Types A and B should be mainly treated by choledochocystojejunostomy (Roux-en-Y), while in type C an endoscopic transpapillary splitting is recommended.

[Examinations of upper gastrointestinal bleeding - value of emergency endoscopy (author's transl)].

The treatment of the acute upper gastrointestinal bleeding can be improved by using standardized immediate actions, as there is endoscopy in emergency diagnostics. Endoscopy gives much higher certainty in pre-operative diagnostic, better possibility of planning and more exact timing of the operation. Therefore emergency endoscopy should be done in any case of acute upper gastro-intestinal bleeding.

[Gastrointestinal endoscopy in surgical patients (author's transl)].

Gastrointestinal endoscopy with flexible glass fiber instruments is of increasing importance in surgery. Preoperative endoscopic examinations bring good progress in planning the operative procedure, especially concerning proximal selective vagotomy, pancreas surgery and reoperations on the large intestine. By applying postoperative endosocopic controls mucosal alterations can earlier be detected in the area concerned than by radiological methods; this has to be emphasized especially in view of patients operated upon for cancer. Emergency endoscopy in massive gastrointestinal bleeding is one of the outstanding tasks. Under certain circumstances risky abdominal operations can be avoided by therapeutic endoscopy.
