title: The morbidity of surgical access: a study of open versus laparoscopic cholecystectomy.
abstract: A prospective non-randomized study of 37 adult patients undergoing open cholecystectomy and 40 patients undergoing laparoscopic cholecystectomy was undertaken to test the hypothesis that surgical access alone has a significant impact on postoperative morbidity. Specifically the study examined the deterioration of pulmonary function, development of pulmonary complications, postoperative narcotic requirement and total bed stay as markers of postoperative morbidity. The results showed that significantly less deterioration of pulmonary function occurred in patients treated using the laparoscopic approach. In this group there was also significantly less requirement for postoperative narcotics, less consequent development of pulmonary complications and a shorter bed stay in hospital. The study documents the substantial impact of surgical access on postoperative morbidity and highlights the benefits of the laparoscopic 'minimal access' approach.
