Clinical relevance of a cysto-colic peritoneal band found incidentally during cadaveric dissection.

The peritoneal lining of the abdomen is one the most important and complex of the serous membranes. We report a case of persistence of a peritoneal band extending from the gall-bladder to the right colic flexure. This unusual embryological remnant of the foregut could lead to duodenal obstruction or even atrophy of the gall-bladder. The persistence of these developmental components could create perplexing situations for the laparoscopic surgeons especially if they are unfamiliar with the possible anomalies of this region. Abnormality in the development of mesentery or omentum may result in pathological conditions and CT scans may be exceptionally useful in diagnosing these conditions. A thorough identification and description of these pathologic conditions depends upon the normal appearance of the peritoneal cavity and its specialized folds ascertained accurately through new imaging techniques.
