Comparative Study
Reusable instruments are more cost-effective than disposable instruments for laparoscopic cholecystectomy.
Health care costs are rising rapidly, and surgeons can play a role in limiting costs of operations. Of the 600,000 cholecystectomies performed each year in the United States, approximately 80% are performed with laparoscopic technique. The purpose of this study was to compare the costs of reusable vs disposable instruments used during laparoscopic cholecystectomy. ⋯ Theoretical advantages of disposable instruments such as safety, sterility, and better efficiency are not borne out in literature review. In addition, the environmental impact of increased refuse from disposable instruments could not be exactly defined. With the consideration of significant cost savings and the absence of data demonstrating disadvantages of their use, reusable instruments for laparoscopic cholecystectomy, are strongly recommended.

Extended laparoscopic operations are being performed increasingly in high-risk patients. To assess the effects of increased intraabdominal pressure (IAP) and positive end-expiratory pressure (PEEP) on the hemodynamic and respiratory system during extended procedures a carbon dioxide pneumoperitoneum was artificially induced in 10 dogs undergoing laparoscopic pelvic lymphadenectomy. ⋯ Measurement of arterial carbon dioxide and fractional end-tidal carbon dioxide revealed significant CO2 retention. We conclude from the results that laparoscopic pelvic lymphadenectomy should be performed in high-risk patients only under general anesthesia with expanded cardiopulmonary monitoring.
