title: Giant horseshoe intra-abdominal abscess.
abstract: A study of 12 patients with giant horseshoe abscess of the abdominal and pelvic cavities seen at the Surgical Services of the University of Cincinnati Medical Center has emphasized the complexity and bizarre nature of these lesions. These infections represented a huge abscess or series of communicating abscesses extending from one subphrenic space along the corresponding paracolic gutter into the pelvis, up and along the opposite paracolic space, and into the other subphrenic space. Since these lesions occurred infrequently, they were often not recognized until they had become far advanced and had produced profound effects on the patients. The diagnosis was difficult and obscured by various factors including the postoperative state after laparotomy for complex diseases or serious injuries of the biliary tract, the genitourinary tract, or the alimentary tract. An important etiologic component of the formation of these giant abscesses was the continuing escape and collection of large volumes of fluid resulting from lesions of the biliary tract, postoperative hemorrhage, or an unrecognized large perforated peptic ulcer. Nine patients were treated successfully and 3 died. The many diagnostic and therapeutic problems presented by the patients with this interesting and complex lesion have emphasized the importance of earlier and more accurate diagnosis, early and adequate surgical drainage, intelligently applied antibiotic therapy and appropriate supportive treatment. Failure to recognize and drain effectively each of the component sections of this lesion led to continuing sepsis with prolonged morbidity, progressive debility, and death.
