Diagnostic laparoscopy

Abstract

Diagnostic laparoscopy began in a surgical unit in a developing country in 1972. The developers of this technique aimed to hasten diagnosis, reduce patient distress, and improve bed utilization in an overcrowded teaching hospital wherein simple investigations such as x-rays took weeks to materialize. Over a period of 18 years reaching to 1990, 3,200 diagnostic laparoscopies were performed on adults under local anesthesia with no mortality, a complication rate of 0.09%, an 84% diagnosis rate, and 74% undergoing histologic biopsies targeting a wide spectrum of pathology. The equipment cost spread out over the 3,200 patients works out to 30 rupees (0.60 dollar) per patient. With the availability of noninvasive diagnostic aids such as ultrasound, computed tomography, and magnetic resonance imaging used US, CT, MRI under the control of target biopsy, the role of diagnostic laparoscopy has altered. Since 1990, clinicians have had the sophistication of the video camera and the pneumoperitoneum insufflator. Diagnostic laparoscopy is used for the evaluation of liver and peritoneal pathology, abdominal tuberculosis, malignancy, acute abdomen, and abdominal trauma. It often is a prelude to laparoscopic treatment of the underlying pathology, specifically in cases of acute appendicitis.
