[Analysis of the cost-income ratio for open and laparoscopic sigmoid resection].

Based on the example of the sigmoid resection, we did a cost-income analysis evaluating the particular expenses and effects of the new DRG-based medical financing system. We analysed the cost of diagnostic tests, medication and nutrition, surgery, personnel and non medical expenses for 20 open and 27 laparoscopic operated patients. The cost of open surgery was calculated to be 3,288.

[Success and failure with the Demers catheter in dialysis].

Between January 1995 and January 1999 54 Demers atrial catheters were implanted in 48 uraemic patients. Indications for implantation were: urgent need for haemodialysis with missing vascular access (39), fistula occlusion (7), low shunt flow (3) and problems with a previously implanted catheter (5). We observed 7 catheter infections, 5 catheter occlusions, 1 intraoperative air embolism, 3 haematomas and 1 dacron socket dislocation.
