Considering the legal conditions there is no question that with the health reform law (GSG) changes in hospital infrastructure have to be made by the surgeon and the administration cojointly.

[Local effects and changes in wound drainage in the free peritoneal cavity].

In a prospective randomised study 30 mongrel rabbits received two standard colon-resections. Three types of drains were tested: (latex-rubber-) Penrose-drains, rubbertube- and silicontube-drains, which were placed in the lower abdomen. As a closed drainage-system the extraperitoneal tip of the drain was placed in a closed subcutis-pocket.

[Surgical treatment of multivisceral intra-abdominal recurrences and metastases].

From 1988 to 1990, 467 patients were operated a total of 850 times for malignant intra-abdominal tumours. Analysis of these 850 operations revealed that 205 were performed for recurrences with or without metastasis and 59 were performed for metastasis. The operations for recurrences were elective in 158 cases and consisted of 86 local radical procedures and 72 non-radical procedures.

[Acute postoperative psychosyndromes. A prospective study and multivariate analysis of risk factors].

The incidence of postoperative delirium was assessed in 92 patients on a general surgical intensive care unit. Postoperative delirium was diagnosed in 39 patients (42%). Most of the cases were diagnosed on the second postoperative day and the median duration was seven days.
