The role of laparoscopy and thoracoscopy as diagnostic modalities in b
lunt and penetrating abdominal trauma was studied in 35 hemodynamicall
y stable patients who otherwise would have undergone exploratory lapar
otomy because of equivocal diagnostic findings. Minimally invasive lap
aroscopic techniques (single 5 millimeter port) and minimal abdominal
insufflation (8-10 millimeters mercury) were used with general anesthe
sia. Both laparoscopy and thoracoscopy appear to be safe (no complicat
ions), highly sensitive (100%), specific (88%), and accurate (91%) too
ls for determining the presence of surgically significant abdominal pa
thology and the need for therapeutic laparotomy. The appropriate appli
cation of these techniques, possibly under local anesthesia, offers po
tential cost savings.
