Early laparoscopy for the evaluation of nonspecific abdominal pain: a critical appraisal of the evidence.

Patients with nonspecific abdominal pain (NSAP) are frequently seen in emergency departments. Different studies have suggested that early laparoscopy (EL) could be an adequate tool to accelerate diagnosis and therapy. The aim of this study was to assess the effectiveness of EL in terms of diagnosis, persistence of NSAP, mortality, morbidity, cost, hospital stay, and quality of life relative to observation in NSAP.
