Clinical Trial Summary

Perforated diverticulitis of the colon can be complicated by peritonitis, either purulent or fecal. Both are life threatening conditions requiring emergency surgery. The background in terms of reasons for inflammation (diverticulitis) and perforation to develop is unknown. In this study we focus on specific changes associated with inflammation, both in tissues and of fecal and mucosal microbiota.

Description:

A prospective study of abdominal fluid, periferal blood, tissues as well as feces in Patients (perforated diverticulitis with peritonitis undergoing emergency surgery, Group I), and in Controls (patients operated due to colorectal cancer, Group II; patients with mild diverticulitis not needing surgery, Group III). Immune acitvity in abdominal fluid and periferal blood by immunoassay of 92 individual proteins. mRNA expression of 96 specific genes in tissue samples. Quatification of bacterial diversity in feces and colon mucosa.
