A case series of Extra-peritoneal spread of perianal abscess: a rare complication of perianal abscess - Experience from a tertiary care centre in India.

Extra-peritoneal spread of perianal abscess is a rare form of anorectal disease responsible for significant morbidity. We present a case series of 10 patients who presented with abdominal pain as a common symptom. 9 of 10 were not diagnosed at presentation to index centre. A proper examination of the perianal region as well as abdomen can help us suspect this condition clinically and can be confirmed with cross sectional imaging. Draining seton with adequate drainage of both perianal and extra-peritoneal component is the key treatment.
