Chilaiditi Syndrome: A Case Report, Literature Review, and Proposition of a Novel Management Staging System.

Chilaiditi's sign refers to colonic interposition between the liver and the diaphragm in the right subphrenic space secondary to the relaxation of the suspensory ligaments of the right colic flexure. The diagnosis of Chilaiditi's sign is based on radiological findings with the following three criteria: 1) The right hemidiaphragm must be adequately elevated above the liver by the intestine, 2) the bowel must be distended by air to illustrate pseudo-pneumoperitoneum, and 3) the superior margin of the liver must be depressed below the level of the left hemidiaphragm. In this report, we present the case of a 49-year-old female presenting with signs and symptoms suggestive of Chilaiditi syndrome managed with laparoscopic surgery. We also present a literature review with a summary of previous studies and propose a novel management staging system for this syndrome.
