These patientswere assessed as: first and second diagnosis; secondary peritonitis type; antibiotic-therapy;lavages setup; laparostomy´s time; complications and the end of the treatment.We study 10(83.3%) men and 2(16.7%) women, with average age of 39,3 (15-57).First diagnosis: inflammatory abdomen acute 6(50%), block acute abdomen 2(16.7%),perforative acute abdomen 2(16.7%), fistula 1(8.3%) and intracavity abscess1(8.3%). Secondary diagnosis: colon perforation in 4(33.3%), intracavity abscess3(25%), anastomoses dehiscence 3(25%), 1(8.3%) with sigmoid perforative cancerand 1(8.3%) with colon necrosis. Fecal peritonitis was found in 10 patients(83.3%) and purulent in 2(16.7%). The antibiotic-therapy was made during nineteendays. Lavages on demand 6(50%), planned with 4(33.3%) and mixed setup in 2(16.7%).The average time of the laparostomy was 10,9 days (1-36). Complications: eviscerationin 2 cases (16.7%) and fistulization in only one (8.3%). Four patients died.
