Operative management of intra-abdominal infections.

Operation for intra-abdominal infection aims to prevent further contamination of the abdominal cavity, treat the underlying source of infection, and prevent residual or recurrent sepsis by cleaning the peritoneal cavity. Aggressive attempts at early diagnosis are warranted, even if laparotomy is occasionally required for diagnostic as well as therapeutic purposes. Conversely, the degree to which more aggressive methods of peritoneal debridement are helpful is the subject of great controversy that can be resolved only by prospective, randomized multicenter trials. Current standard treatment consists of closure, drainage, or excision of the source of contamination; intra-operative saline or antibiotic lavage of the peritoneal cavity; fascial closure; and secondary or delayed primary closure of the wound.
