Abstract:
PURPOSE: During liver transplantation (LT), complications of the hepatic artery have been decreased because of microsurgery in reconstruction of hepatic artery has been widely adopted. However, in an early step of the LT program, hepatic artery reconstruction generally tends to be done with the help of a micro-surgeon from the the plastic surgery in most of Korean medical centers. In our center, we also have done reconstruction of the hepatic artery using a microscope and the skills of a plastic surgeon. We did this between Feb, 2005 and Jun, 2008 for liver transplantations. The increased the need for micro-surgeons in liver surgery as increased the cases of liver transplantation steadily. After training general surgeons of the surgical department who had no experience with microsurgery, we invested in the micro-surgery of hepatic artery reconstruction. Here we report the result of that investment. METHODS: Liver transplant patients (n=176) were enrolled between Feb, 2005 and Jul, 2009. Between Jul, 2008 and Jul, 2009, 28 cases of reconstruction of the hepatic artery were done by a general surgeon who had micro-surgery training. Before training in hepatic artery reconstruction, the general surgeon spent 3 months being introduced to micro-surgery in the micro animal laboratory. Because the training was repeated, the surgeon became skilled in doing artery anastomosis using rat's abdominal aorta. At the same time, we trained a plastic surgeon to do hepatic artery reconstruction during liver transplantation as the first assistant. From Jul, 2008 to the present time, the general surgeon was exclusively in charge of hepatic artery reconstruction during liver transplantation. Hepatic artery reconstruction was done using a microscope. Stitching was done using 8-0 or 9-0 nylon, and an interrupted end-to-end anastomosis was done. After hepatic artery reconstruction, artery flow was confirmed by ultrasonic doppler. For group A patients, left lobe grafts were used in 33, right lobe grafts in 73, dual grafts in 6, and whole liver grafts in 36. RESULTS: For group B patients, left lobe grafts were used in 1 and right lobe grafts in 21, while whole liver grafts were used in 6. In Group A, hepatic artery complications occurred in 5 cases (3.3%), and in Group B such complications did not occur (0%). There was no statistical difference (p=0.312). CONCLUSION: For hepatic artery reconstruction, during micro-surgery under a surgical microscope, it is thought that it is best to invest in a general surgeon who has been trained in micro-surgery. We suggest that a general surgeon is suitable for hepatic artery reconstruction after only a short time of micro surgery training.
