Laparoscopy in general surgery.

The results of diagnostic laparoscopy under general anaesthetic in 81 general surgical patients have been reviewed. A tissue diagnosis was achieved in 25 of 42 patients (60 per cent) suspected to have widespread intra-abdominal malignancy with minimal preoperative investigation. Extensive investigation, excluding only computerized tomography, failed to achieve a diagnosis in 25 patients with an intra-abdominal mass. Subsequent laparoscopy allowed diagnosis of 22 of these patients (92 per cent). Severe persistent and unexplained abdominal pain in 14 patients was diagnosed at laparoscopy in only one patient (7 per cent) and the procedure did not influence the subsequent course of events in the remainder. There was no mortality and the morbidity (4.9 per cent) compares well with that of laparotomy in similar patients. Laparoscopy failed in 5 patients (6.2 per cent) due to the presence of dense intraperitoneal adhesions.
