RESUMO
This paper presents a case report of 5 years old boy who presented with abdominal pain and fever to the pediatric reception room since four weeks. He was examined and investigated and the possibility of appendiciditis was excluded and a diagnosis of acute non specific mesenteric adenitis was coined. Follow-up medical treatment with antibiotics and conservative measures yielded a parietal abscess in the right iliac region. Simple incision drainage revealed pus and intestinal fecal content. A fecal fistula of appendicular origin was thought for and conservative management continued. However, investigation revealed a communication to the small intestines, and the multi-orifices draining fistulae caused a severe water and electrolyte imbalance with acidosis and emaciation. A decision at exploration revealed a complicated Meckel's diverticulitis, stuck to the abdominal wall and penetrating the muscular wall to end in an arborisation of fistulae in the right iliac fossa and right lumbar region. Resection anastomosis ensured a sound healing of the condition. The peritoneal cavity was exempted from any leak or peritonitis
