We report a new approach for laparoscopic anatomical left lobectomy. Although laparoscopic limited resection of the liver has been reported, major liver surgery with a laparoscopic approach remains uncommon. Obstacles to routine laparoscopic surgery on the liver are mainly related to difficulty in retraction with current instrumentation, difficulty in assessing safe margins of resection without the use of tactile sense, and the difficulty of safe parenchymal dissection laparoscopically. We introduce a hand-assisted method that can help in resolving the difficulties and pitfalls associated with laparoscopic liver resection, and in making this surgery safer. The hand is the best atraumatic liver retractor in laparoscopic resection and facilitates the use of laparoscopic ultrasonography. Stable hemostasis can be achieved by proper manual application of vascular clips in case of vascular injury. The hemihepatic inflow control technique used in the present case was the en masse occlusion of Glisson's sheath of the left hemipedicle at the bifurcation. This technique was used exactly the same as in open surgery. Major vessels such as the left hemipedicle and left hepatic vein were dissected by endovascular cutter. The patient had an uneventful, quick postoperative recovery. This technique allows a minimally invasive anatomical major surgery for liver tumors.
The purpose of this study was to examine the feasibility of contrast-enhanced virtual MR cholangioscopy (CE VMRC). Intraluminal views of the extrahepatic biliary tree were generated in ten patients undergoing abdominal MRI post mangafodipir trisodium administration employing coronal 2.5-mm 3D fast low-angle shot (FLASH) images (TR 6.8 ms, TE 2.3 ms, matrix 195 x 512) with fat saturation and a commercially available software. Contrast-enhanced VMRC was compared with single-shot turbo spin-echo T2-weighted MR cholangiography (T2 MRC) in terms of ductal visualization and artifact presence, utilizing a five-point grading scale. Four anatomic segments were evaluated: the intra- and extra-pancreatic segment of the common bile duct (CBD), and the cystic duct and the area of hepatic duct bifurcation. Both CE VMRC and T2 MRC depicted 38 of 40 segments. There were no significant differences between CE VMRC and T2 MRC in ranking ductal segments visualization ( p=0.27). The high contrast between intraluminal fluid and extraluminal tissues facilitated the generation of endoscopic views. Contrast-enhanced virtual MR cholangioscopy is a feasible technique providing endoscopic views of the CBD. Initial results show correlation of CE VMRC with projectional MR cholangiography.
