ABSTRACT
92 cases of post-operative peritonitis in digestive surgery are recorded: - Diagnosis is difficult inspite of the multiplicity of symptoms which are variable and non specific. - Clinical presentation is dominated by the frequency of infectious symptoms essentially fever, neuro -psychic, hemodynamic and respiratory disorders. Abdominal signs though advocatory are late. - Early reoperation represents the only possibility of survival for the patients. It must contain a way large, a complete peritoneal washing, an eradication of the source of peritonitis and an effective drainage. - A correct ressucitation effective before, during, and after operation is fundamental. - The prognosis of this fearful complication improves clearly in case of operation and the mortality rate declines from 100% [in absence of operation] to 47.4% [in case of operation]. Because of the high mortality rate, [44.4%], this post-operative complication has to be prevented
