Endoscopically drained abdominal abscess compressing the sigmoid.

Intra-abdominal abscesses (IAA) complicate numerous medical and surgical pathologic conditions. Accurate radiological diagnosis combined with percutaneous or surgical drainage and antibiotics is the current standard of care for IAA. We herein report a case of a 52-year-old woman with a 10-day history of fever and abdominal pain. An intra-abdominal abscess externally compressing the sigmoid was revealed and successfully drained during colonoscopy.
