[The therapeutic results of programmed relaparotomy in diffuse peritonitis].

The therapeutical concept of programmed relaparotomy was performed in 184 patients with diffuse peritonitis from 4/1984 to 4/1991. Clinical results were prospectively documented and a total of 46 variables (e.g. risk factors, clinical parameters, laboratory tests, microbiological screenings, score systems) both univariate and multivariate were tested for prognostic significance. Total lethality rate was 26% (48/184 patients). If complete eradication of the source of infection was surgically achieved (150 patients/82%) lethality rate was only 9%. In contrast, lethality rate was 100% in patients with unsuccessful surgical focus eradication. Eradication of the source of infection during the first operation (104 patients/56%) resulted in a lethality rate of 6%, compared to 17% for patients who needed two or even more operations (46 patients/25%). Eradication of the source of infection during the first laparotomy ("focus eradication on time") was the most important prognostic parameters. Of further prognostic significance but with declining importance where serum-creatinine at the beginning of the treatment, patient's age (greater than less than 70 years) and preexistent hepatic disease.
