Intra-abdominal abscess

Intra-abdominal abscess refers to the localized accumulation of pus formed when a certain space or site within the abdominal cavity undergoes tissue necrosis and liquefaction, which is encapsulated by intestinal loops, viscera, abdominal wall, omentum, or mesentery. It includes subphrenic abscess, pelvic abscess, and interloop abscess. Various diseases causing secondary peritonitis, abdominal surgery, and trauma can all lead to this condition, with infection being the main cause of abdominal abscess.
