Two-millimeter minisite mini-laparoscopy for rescue of dysfunctional continuous ambulatory peritoneal dialysis catheters.

In addition to peritonitis, mechanical outflow obstruction is the most common complication of continuous ambulatory peritoneal dialysis. If conservative methods are unsuccessful, the insufficient catheter must be placed in the right position or freed surgically. Currently, laparoscopy appears to be the method of choice in these cases.

[Changes in portal circulation after esophageal transection].

Unlabelled: 104 patients with hepatic cirrhosis and esophageal varices were treated between 1979 and 1996 using the modified Sugiura (Hirashima) procedure. In 60 cases (18 F, 42 M) portal hemodynamics (portal blood velocity (PBV) and portal blood flow (PBF)) were investigated using Doppler-USG method. In 40 cases a prospective study before operation, 2 weeks, 3 months after operation and then in 6-month intervals was completed.

[Evaluation of esophageal motility after its resection and extensive devascularization].

Unlabelled: Almost complete lack of information concerning esophageal motility after non-shunt operations due to bleeding esophageal varices was the main stimulus of this study. Thirty seven patients from 112 treated for bleeding esophageal varices in our Clinic in the years 1993-1997, were studied. To evaluate esophageal parameters the Autronic GmbH D-7500 pH-meter, and from 1995, the Microdigitrapper 2 MB (Synectics) System were used.
