Abstract:
Objective To evaluate the intraoperative advantage and postoperative outcomes of threedimensional laparoscopic common bile duct (CBD) choledochoscopic exploration by micro-incision made at the cystic duct-CBD junction (LCBDEM) for gall stones and choledocholithiasis.Methods From January 2014 to December 2015,31 patients were operated under 3D LCBDEM (study group) and 37 patients under 2D LCBDEM (control group).The outcomes of patients in two groups were compared,including total procedure time (TPT),modified procedure time(MPT),suturing time(ST) and the wrong grasping per 100grasps(WG)of the LCBDEM.8 surgeons experienced in 3D LCBDEM were asked to fill in a subjective questionnaire.Results In control group,the TPT,MPT,ST and WG were (148 ± 47) min,(108 ± 42)min,(20 ±3)min and (19 ±4)per 100 grasps,respectively.In study group,the TPT,MPT,ST and WG were (148 ± 46) min,(9 1 ± 25) min,(1 8 ± 3) min and (8 ± 2) per 100 grasps,respectively.There were significant differences in MPT (t =-2.026,P ＜ 0.05),ST (t =-2.239,P ＜ 0.05) and WG (Z=-7.062,P ＜ 0.001).In subjective questionnaire survey,3D laparoscopy has advantages over 2D laparoscopy in visual and operation experience.But 3D laparoscopy made eyes more easily tired and dizzy.31 aparoscopy was inferior to 2D laparoscopy in spinning the camera around to get optimal field of vision.Conclusions 3D LCBDEM shortens procedure time and suturing time,increases operating accuracy and safety by providing high definition stereovision.
