Abdominal cocoon: a case series

We describe a series of 18 cases of abdominal cocoon in patients presenting with features of small intestinal obstruction or perforative peritonitis, nine of whom had tubercular aetiology while the rest were idiopathic. Manifestations of abdominal tuberculosis such as mesenteric abscesses, enlarged and caseating mesenteric lymph nodes, and tubercles over the bowel serosa were found in only 55% patients who were ultimately diagnosed to have Tubercular aetiology. We conclude that a high index of suspicion for this rare cause of a common surgical emergency is desirable.
