In Viet Nam, the method of liver resection developed by Prof. Ton That Tung at Viet Duc Hospital was approved worldwide. After that realisation liver trasplantation had been considered. In 1965 Ton That Tung and his collaborators had carried an experiment to graft total liver on dog and had preliminary success, afterwards human liver tranplantation began to prepare. In 2002, in Viet Duc hospital, 15 cases of experimental liver tranplantation were performed totally in pig to get experience and the results were encouraged. For implementing a first case of liver transplantation in late year 2003 and for developing this technique in some main institution in next time, some preparation must be started

The expression of HB-EGF (heparine binding epidermal growth factor) in cells of mice increased just after partial level removal in hapatectomy and reached maximal value 3 hours later. TGF-A expression in mice cells after 2/3 hepatectomy reduced in comparing with control in 3 first hours later and increased in 6 hours later

The study was divided into 2 phases: In phase 1 (1997), the left lobes were removed and transplanted autogenously to other sites. Phase 2 (1998 - 2000) was performed according to the human liver transplantation model. Results: In phase 1, the left lobes were removed in 6 animals, 4 animals were transplanted autogenously at spleen holes. 3/4 grafts had good outcomes. One out of 4 grafts discoloured with poor circulation. In second phase, 23 animals were removed left lobes, 21/23 grafts met requirements, and 5/23 animals had complications and dead soon postoperation. 18/23 animals remained to be survival postoperation. Among liver-received pigs, 5 animals were dead perioperation. 14/18 grafts had good outcomes. 4/18 grafts discoloured. The average extra survival of liver-received pigs was 14.6 hours

PURPOSE: Healey divided segment IV of the live as the 'superior portion (IVa) ' and the 'inferior portion (IVb) '. On the contrary, Couinaud suggested that there was no useful purpose in dividing segment IV because of several reasons. Our goal is to evaluate the safety of the 'isolated IVb (inferior) resection of the liver' via performing the dissection of cadavers. METHODS: There were ten total cadavers. Cadaver dissection proceeded with respect to the Glissonian pedicle, the portal vein and the bile duct, respectively. The total number of Glissonian pedicles at segment IV was measured. The distance between the origins of the IVa and IVb branches was measured. Additional pedicles that were known to exist at segment IVa were also evaluated. RESULTS: The mean number of Glissonian pedicles in segment IV, IVa, and IVb was 5 (+/-1.3), 1.6 (+/-7), and 3.4 (+/-0.9), respectively. The mean distance between the origins of the IVa and IVb branches was 5.6 mm (+/-3.9 mm). Two of 10 cases had a very short distance between the origins that were considered as having common origin. Additional pedicles were identified at the Lt. main Glissonian pedicle in all the cases (8 cases: 1 each, 2 cases: 2 each). CONCLUSION: Considering the possible existence of a common origin of segment IVa and IVb Glissonian pedicles, there is the risk that the segment IVa will be injured during 'iso lated IVb resection'. Inevitable ligation of the additional pedicle of segment IVa from the Lt. main Glissonian pedicle can be made during the 'isolated IVb resection'. Therefore, we think that 'isolated IVb resection of the liver' can be safe only when the surgeon divides the branches of segment IVb with meticulous preservation of the IVa branches.

The extent of excision and necessity of hepatectomy in type IVa choledochal cyst has not been clarified. We performed left lobectomy of the liver for complete excision of the cyst in a thirty-year-old male patient with type IVa choledochal cyst. Postoperative recovery was untroubled and outcome was satisfactory. Complete excision of the cyst including hepatectomy is an acceptable operative management for patients with type IVa choledochal cyst. This procedure can eliminate the possibility of subsequent cancer arising from remaining cyst.

PURPOSE: Couinaud described segment IV as being equivalent to segments II and III, as the umbilical portion of the portal vein (PV), and its equal branch of segment II, originated from the transverse portion of the PV. On the contrary, Healey suggested the presence of left lateral and medial segments, on the basis of umbilical fissure. Recently, some author have claimed the branch of segment II originated from the distal portion of the ligamentum venosum (LV), and that this branch was not equal to, only a branch of, the umbilical portion. Our goal was to evaluate the surgical anatomy of the left lobe of the liver through dissecting Korean cadavers. METHODS: The number of cadavers dissected totaled 10. PV, its branches, and the LV were dissected and the length of the transverse portion measured. The distance between the origin of the transverse portion and that of the segment II branch were also measured. RESULTS: The branch of segment II originated from the distal portion of the LV in all 10 cases. The length of the transverse portion was 18.8+/-5.8 mm, and the distance between the origins of the LV and segment II branch was 7.0+/-3.1 mm. CONCLUSION: Considering the embryology of the liver, as well as the above result, the umbilical portion and segment II branch were not equal anatomic structures. The umbilical portion and LV are equal anatomic structures. The branch of segment II is only one of the branches of the umbilical portion. We think Healey's classification is more accurate for the left lobe of the liver.
