Clinical application of domestic harmonic scalpel in laparoscopic cholecystectomy / 中国微创外科杂志

ABSTRACT

Objective To explore the clinical value of domestic harmonic scalpel in laparoscopic cholecystectomy. Methods Modified laparoscopic cholecystectomy (LC) was performed in 36 cases under general anesthesia. The operation was completed by using domestic USI harmonic scalpel in 21 cases (USI Group) and by using imported harmonic scalpel in 15 cases (GEN Group). Results The operation was laparoscopically accomplished in both of the groups, without conversions to open surgery. Of the USI Group, the operating time was 42.6?7.5 min, the postoperative drainage was 34.3?14.0 ml, the length of postoperative hospitalization was 4.9?0.9 d, the speed for cutting cystic duct was 335.1?180.3 ?m/s, the speed for cutting cystic artery was 524.2?127.8 ?m/s, and the denaturalization width of cystic duct was 2 047.6?376.3 ?m. Of the GEN Group, the operating time was 47.0?9.0 min, the postoperative drainage was 38.0?3.9 ml, the length of postoperative hospitalization was 4.3?0.9 d, the speed for cutting cystic duct was 403.5?120.1 ?m/s, the speed for cutting cystic artery was 513.5?125.9 ?m/s, and the denaturalization width of cystic duct was 2 266.7?306.3 ?m. There was no differences in these parameters between the two groups ( P
