Diagnostic laparoscopy: a survey of 92 patients

Abstract

From January 1991 to June 1993 the authors performed 92 diagnostic laparoscopies when physical examination, laboratory tests, and noninvasive imaging techniques failed to provide accurate diagnoses. Thirty-three patients (36%) underwent laparoscopy to ensure or exclude diagnosis in suspected intra-abdominal malignancy or to assess the operability in the cases of known cancer; 31 patients (34%) were evaluated for chronic abdominal pain; 15 patients (16%) were evaluated for acute abdominal pain; 9 trauma patients (10%) were evaluated to exclude or confirm penetration of the peritoneum or laceration of intra-abdominal organs; and 4 patients (4%) were operated on for miscellaneous conditions. Of the 92 patients, laparoscopy led to diagnosis in 80 patients (87%), a laparotomy was avoided in 78 patients (85%), and operative treatment was done laparoscopically in 65 patients (71%). Diagnostic laparoscopy will not replace laparotomy in every instance. However, in selected groups of patients, it may be used to yield diagnosis and help to avoid unnecessary laparotomy.
