In order to evaluate the prognostic value of simple clinical parameters and the Mannheim PeritonitisIndex (MPI) 438 patients with abdominal infection entered a prospective study. 300 of them were managed by closed treatment with drainage, 138 by open treatment with planned relaparotomy. 63 patients (14.4%) died, 34 of them due to sepsis, 29 due to another(More)
We propose a novel interactive multi-label RGB-D image segmentation method by extending spatially varying color distributions [14] to additionally utilize depth information in two different ways. On the one hand, we consider the depth image as an additional data channel. On the other hand, we extend the idea of spatially varying color distributions in a(More)
Scoring systems are mandatory to quantify the severity of abdominal sepsis on the basis of objective criteria. The Mannheim Peritonitis Index (MPI) is a disease-specific score based on easy to handle clinical parameters. APACHE II is a large-scale general scoring system with acute physiological and chronic health parameters. To evaluate the prognostic value(More)

Of 1,134 patients treated for rectal cancer from 1973 to 1985, local therapy was used in 310. Forty-two underwent local excision and the operative morbidity and mortality were lower than after radical operations. The 5-year survival rate was 84%. This treatment should be reserved for patients who have totally resectable tumors of 3 cm or less in size and of(More)
307 Patients with intraabdominal infections were operated between 8/1988 to 8/1991. Simple clinical parameters (according to the Mannheimer Peritonitis-Index) were evaluated before treatment. The classical therapeutic concept of one-stage laparotomy with drainage of the abdomen was performed in 223 patients initially. Because of recurrent infection and(More)
Determinants for homologous blood transfusion and its influence on postoperative and long-term results were evaluated in 439 curatively resected colorectal cancer patients. The rate of transfusion was significantly higher in rectal cancer, large tumors, advanced pT stage and extended resection but not in tumor stenosis, lower graded tumors, advanced Dukes(More)
Robots that know what they are doing can solve their tasks more reliably, flexibly, and efficiently. They can even explain what they were doing, how and why. In this paper we describe a system that not only is capable of executing flexible and reliable plans on a robotic platform but can also explain control decisions and the reason for specific actions,(More)
In a clinical report the results on 500 patients operated on with acute and complicated colonic diverticulitis from 1988 to 1999 are reported. In 401 elective or early elective operated cases mostly (392) a 1-stage operation with resection and primary anastomosis could be done (since 1997 by minimally invasive technique in 106 cases) with a mortality rate(More)
An important intention of flow cytometric investigations is to obtain biochemical and biophysical information about cells which is suitable for automated tumor diagnosis. In this study, the ploidy status, the intracellular pH value, the intracellular esterase activity, and the cell volume of vital cells and the DNA and cell volume of dead cells were(More)
