Discussion on risk guard in dissection of cholecyst from its bed during laparoscopic cholecystectomy

Objective To discuss risk factor and operation guard in dissection of cholecyat from its bed during laparoseopic cholecystectomy.Methods The clinical data of 490 cases of laparoscopic cholecystectomy dissect cholecyst from its bed by traditional method during were retrospectively analyzed and simultaneously perspective study on 500 cases of improved laparoscopic cholecyatectomy dissecting cholecyst from its bed.Results There are 3 cases in hemorrhea due to injuring bed brancha of arteria cystica posterior branch,2 cases in bed brancha of arteria cystica posterior branch haemorrhage,5 cases in postoperative bile leak,2 cases in variant right hepatic portal vein injury,1 case in variant right hepatic duct in the 490 cases of laparoscopic choleeystectomy by traditiorhI method.Using our new technique exposed,and then ligated 39.6%(198/500)bed brancha of arteria cystica posterior branch,11.2% (56/500)bed brancha of venae hepaticae intermediate almost in fight side of cholecyst bed,2.2%(11/500)dilated aberrant bile-duct duct.We separated and then protected 0.6%(3/500)unusual right hepatic duct being exposed,0.4%(2/500)right liver branch of portsl vein.Conclusion There are some larvate risk in isolation of choleeyst from its bed during laparoseopic cholecystectomy.Unexpected injury happen during LC,and it ought tO be open cholecysteetomy The improved method provides a safe,efficiency operative procedure.
