Abstract
Extra-abdominal abscesses of gastrointestinal origin developing within the lumbar subcutaneous tissues are extremely rare. We report two cases of retroperitoneal bowel perforation presenting spontaneously at admission with a lumbar abscess trespassing the lumbar triangle of Petit, a classical "locus of minus resistencia" of the posterior abdominal wall. The first case was caused by perforation of a retrocecal appendicitis--being concomitantly responsible of a necrotizing fasciitis of the thigh--and in the second case perforation was caused by left colonic diverticulitis. In both cases, the full diagnosis was made with abdominal CT. The patients were threatened by a two-step surgical approach comprising a direct posterior percutaneous drainage of the abscess followed by classical laparotomy.
