RESUMO
We describe the case of a patient affected by the Chilaiditi's syndrome, the interposition of the small or large bowel between the inferior face of the diaphragm and the liver, a rare anomaly, often asymptomatic. A 50-year-old man came to our outpatients clinic because of persistent pain in the right abdominal region. Two attempts to perform colonoscopy failed because of the impossibility of passing through the transverse colon. A double contrast enema indicated only sigmoid diverticulitis. Only after abdominal radiography was the abnormal position of the right colon noted. At surgery the right colon was totally intraperitoneal and positioned between the diaphragm and liver, which was smaller than normal. The right colon was repositioned and fixed to the anterior abdominal wall. The postoperative course was uneventful and the right abdominal pain disappeared completely. In conclusion, surgical treatment of Chilaiditi's syndrome may be required in cases of persistent abdominal pain.
