Role of diagnostic techniques in the initial evaluation of stab wounds to the anterior abdomen, back, and flank.

TL;DRAbstract

Despite the widespread availability of firearms, stab wounds to the abdomen, back, and flank continue to account for a significant number of injuries. The proper sequencing of diagnostic modalities in this patient group is constantly undergoing change. We report our experience with these injuries and present a new algorithm for the use of currently available diagnostic procedures. In 1987, 162 patients were seen, 103 with anterior abdominal wounds and 59 with back and flank wounds. Patients with shock, peritonitis, and evisceration were resuscitated and explored. The remainder of the cohort underwent tap and lavage, and patients with a negative study were observed. Patients with back and flank wounds underwent contrast enhanced computerized tomographic enemas (CECTE). Seventeen patients underwent immediate exploration and 108 of the 162 patients were spared exploration. Fifty-four patients were explored with six negative laparotomies. Of the 126 taps and lavages, the false positive rat
