Blind versus open approach to laparoscopic cholecystectomy : a randomized study . Intraabdominal structures may be damaged during blind introduction of the first trocar for laparoscopic operations . In this study , 150 patients with gallbladder lithiasis who underwent laparoscopy were randomly assigned to two groups , a blind ( V group ) or an open ( H group ) , in order to compare the results and the rate of complications . No mortality was observed . Major complications occurred in 3/75 ( 4 % ) patients of the V group and in 1/75 ( 1.3 % ) patient of the H group ( p < 0.05 ) . Minor complications occurred in 5/75 ( 6.7 % ) patients of either group . The achievement of pneumoperitoneum required 4.5+/-0.4 min in the V group and 3.2+/-0.2 min in the H group ( p < 0.05 ) . The open laparoscopic technique is safer and faster than the blind approach ; therefore , it is proposed that this approach be routinely used in all laparoscopic procedures .
