[Critical study on dead cases in recurrent early stomach cancer (author's transl)].

35 deaths of 299 operated early stomach cancers have been studied retrospectively. These cases can be grouped in the following categories: 2 deaths directly due to operation, 7 due to recurrence of carcinoma, 19 due to other diseases including cancer in other sites and 7 cases in which the real causes of death could not be elucidated. Special attention was paid on the 7 recurrent cases: In 4 of 7 patients the histological study revealed lymph and blood vessels invasion in their resected stomachs, lymphnodes metastases in 5 patients and positive cut-end in 2 patients. 5 of 7 patients died within 3 years after operation.

Operative and postoperative choledochofiberoscopy.

Choledochofiberoscopy is effective for both diagnosis and therapy. It is a valuable diagnostic technic because it permits a definite diagnosis and it allows the surgeon to determine the operative method by direct viewing and by biopsy of the biliary tract wall. Choledochofiberoscopy is therapeutically valuable because it permits cleaning of the bile duct, the removal of retained or remnant stones in the common and intrahepatic ducts, and the removal of granuloma and benign tumor with forceps under direct vision.

Operative nephroscopy with fiberoptic scope: preliminary report.

New fiberoptic scopes, originally designed for biliary tract operations, were used in 23 cases for removal of residual calculi at pyelolithotomy and for examination of the renal pelvis and ureter. The external diameters of the scopes are 6.6 mm. (CHF-X1) and 4.5 mm. (CHF-X2). Water irrigation and forceps manipulation can be performed simultaneously with the CHF-X1 scope but only irrigation can be done with the CHF-X2 scope. The scopes were reliable and allowed easy endoscopic forceps manipulation. Improvements for an ideal fibroptic nephroscope are discussed.

Labelled gelfoam in transcatheter arterial embolization of renal cell carcinoma.

Six patients with renal cell carcinoma underwent transcatheter arterial embolization with Gelfoam labelled by metallic clips. The embolization procedure was more easily monitored by fluoroscopy, and the complication of peripheral embolization was prevented. Tumor regression can be evaluated by changes in the distribution of the metallic clips on plain films.
