title: Preoperative laparoscopy in diagnosis of acute abdominal pain.
abstract: During 1973, 56 patients on one of three general surgical services at the Peter Bent Brigham Hospital, Boston, Massachusetts, who were judged to require hospital admission for acute abdominal pain were dividied into two groups. This division was determined by whether or not the physician responsible thought a definite diagnosis could be established on clinical grounds. 27 patients were thought to have a definite diagnosis and underwent laparotomy without preoperative laparoscopy; at laparotomy, 6 of these patients (22%) had no operable lesion. An additional 29 patients had severe abdominal pain and required observation in hospital. An exact diagnosis could not be clinically established in these patients, and many would in the past have required exploratory laparotomy. These 29 patients underwent laparoscopy resulting in all but 1 (4%) having the presence or absence of intra-abdominal disease requiring operative intervention definitely established. At laparoscopy, diagnosis was made in 18 patients who did not require laparotomy while 11 had disease requiring laparotomy after laparoscopy. No complications resulted from laparoscopy. The difference in the median length of stay and hospital charges resulted in a saving of one and a half days in hospital and $87 when laparoscopy rather than explatory laparotomy determined that acute  abdominal pain was caused by a condition not requiring surgical intervention.
