BACKGROUND: The safety of donors in living donor liver transplantation (LDLT) should be the primary consideration. The aim of this study was to report our experience in increasing the safety of donors in LDLTs using right lobe grafts. METHODS: We retrospectively studied 37 living donors of right lobe grafts from January 2002 to March 2006. The measures for increasing the safety of donors in LDLT included carefully selected donors, preoperative evaluation by ultrasonography, angiography and computed tomography; and necessary intraoperative cholangiography and ultrasonography. Right lobe grafts were obtained using an ultrasonic dissector without inflow vascular occlusion on the right side of the middle hepatic vein. The standard liver volume and the ratio of left lobe volume to standard liver volume were calculated. RESULTS: There was no donor mortality in our group. Postoperative complications only included bile leakage (I donor), biliary stricture (1) and portal vein thrombosis (1). All donors recovered well and resumed their previous occupations. In recipients, complications included acute rejection (2 patients), hepatic artery thrombosis (1), bile leakage (1), intestinal bleeding (1), left subphrenic abscess (1) and pulmonary infection (1). The mortality rate of recipients was 5.4% (2/37); one recipient with pulmonary infection died from multiple organ failure and another from occurrence of primary disease. CONCLUSIONS: The first consideration in adult-to-adult LDLT is the safety of donors. The donation of a right lobe graft is safe for adults if the remnant hepatic vasculature and bile duct are ensured, and the volume-of the remnant liver exceeds 35% of the total liver volume. 展开更多

AIM To analyze the outcomes of living-donor liver transplantation(LDLT) using left-lobe(LL) or right-lobe(RL) small-for-size(SFS) grafts.METHODS Prospectively collected data of adult patients who underwent LDLT at our hospital in the period from January 2003 to December 2013 were reviewed. The patients were divided into the RL-LDLT group and the LL-LDLT group. The two groups were compared in terms of short-and long-term outcomes, including incidence of postoperative complication, graft function, graft survival, and patient survival. A SFS graft was defined as a graft with a ratio of graft weight(GW) to recipient standard liver volume(RSLV)(GW/RSLV) of < 50%. The Urata formula was used to estimate RSLV.RESULTS Totally 218 patients were included for analysis, with 199 patients in the RL-LDLT group and 19 patients in the LL-LDLT group. The two groups were similar in terms of age(median, 53 years in the RL-LDLT group and 52 years in the LL-LDLT group, P = 0.997) but had significantly different ratios of men to women(165:34 in the RL-LDLT group and 8:11 in the LL-LDLT group, P < 0.0001). The two groups were also significantly different in GW(P < 0.0001), GW/RSLV(P < 0.0001), and graft cold ischemic time(P = 0.007). When it comes to postoperative complication, the groups were comparable(P = 0.105). Five patients died in hospital,4(2%) in the RL-LDLT group and 1(5.3%) in the LLLDLT group(P = 0.918). There were 38 graft losses, 33(16.6%) in the RL-LDLT group and 5(26.3%) in the LL-LDLT group(P = 0.452). The 5-year graft survival rate was significantly better in the RL-LDLT group(95.2% vs 89.5%, P = 0.049). The two groups had similar 5-year patient survival rates(RL-LDLT: 86.8%, LL-LDLT: 89.5%, P = 0.476).CONCLUSION The use of SFS graft in LDLT requires careful tailormade surgical planning and meticulous operation. LLLDLT can be a good alternative to RL-LDLT with similar recipient outcomes but a lower donor risk. Further research into different patient conditions is needed in order to validate the use of LL graft. 展开更多

The aim of this paper is to summarize our experience of using right lobe liver grafts to reduce biliary complications in adult-to-adult(A-A)living donor liver transplantation(LDLT).From January 2002 to October 2007,124 adult patients underwent living donor liver transplantation using right lobe grafts at the West China Hospital,Sichuan University Medical School,China.There was no death in all donors.Biliary reconstruction for 178 hepatic duct orifices from 124 donor grafts was performed which included 106 reconstructions of duct-to-duct anastomoses and 72 cholangiojejunostomy.Nine recipients had biliary complications including six bile lea-kages(four from the anastomotic site and two from the cut surface of the liver graft)and three biliary strictures.With the improved techniques for biliary reconstruction,we have achieved good results in 124 recipients of A-A LDLT.We ascribe our success to the introduction of microsurgical techniques and the use of fixed operators which help in decreasing the biliary complications of LDLT. 展开更多

Objective: To review the experience of donor selec- tion and right lobe hepatectomy in adult-to-adult live donor liver transplantation. Methods: From May 1996 to December 2001, 89 live donor liver transplants using right lobe grafts were performed at Queen Mary Hospital, Hong Kong. All donors had received psychological counseling before donor operations. They were screened by laboratory tests including complete blood cell count, liver and renal biochemistry, and viral serology studies. Com- puted tomography (CT), CT volumetry and hepatic arteriography were routinely performed. All donors underwent the operations using the method designed by us. Results: The median duration of the operations was 8.8 hours. The median blood loss recorded 466 ml. The median intensive care unit and hospital stays were 2 and 10 days, respectively. There was no do- nor mortality. Complications of donor operations in- cluded wound infection, urinary tract infection, bili- ary stricture, cholestasis, subphrenic collection, bowel obstruction and incision hernia, etc. All do- nors have recovered and returned to their previous occupations. Conclusions: Live donation of right lobe grafts for a- dult-to-adult liver transplantation is safe, provided that donor selection is strict and utmost care is exer- cised during the operation. 展开更多

Background: The efficacy and necessity of middle hepatic vein(MHV) reconstruction in adult-to-adult right lobe living donor liver transplantation(LDLT) remain controversial. The present study aimed to evaluate the survival beneficiary of MHV reconstructions in LDLT. Methods: We compared the clinical outcomes of liver recipients with MHV reconstruction( n = 101) and without MHV reconstruction( n = 43) who underwent LDLT using right lobe grafts at our institution from January 2006 to May 2017. Results: The overall survival(OS) rate of recipients with MHV reconstruction was significantly higher than that of those without MHV reconstruction in liver transplantation( P = 0.022; 5-yr OS: 76.2% vs 58.1%). The survival of two segments(segments 5 and 8) hepatic vein reconstruction was better than that of the only one segment(segment 5 or segment 8) hepatic vein reconstruction( P = 0.034; 5-yr OS: 83.6% vs 67.4%). The survival of using two straight vascular reconstructions was better than that using Y-shaped vascular reconstruction in liver transplantation with two segments hepatic vein reconstruction( P = 0.020; 5-yr OS: 100% vs 75.0%). The multivariate analysis demonstrated that MHV tributary reconstructions were an independent beneficiary prognostic factor for OS(hazard ratio = 0.519, 95% CI: 0.282–0.954, P = 0.035). Biliary complications were significantly increased in recipients with MHV reconstruction(28.7% vs 11.6%, P = 0.027). Conclusions: MHV reconstruction ensured excellent outflow drainage and favored recipient outcome. The MHV tributaries(segments 5 and 8) should be reconstructed as much as possible to enlarge the hepatic vein anastomosis and reduce congestion. 展开更多

BACKGROUND: Left liver graft from a small donor will not meet the metabolic demands of a larger adult recipient. To overcome the problem of graft size insufficiency, living donor liver transplantation (LDLT) using the right lobe has become a standard method for adult patients. As the drainage of the median sector (segments V, VIII and IV) is mainly by the middle hepatic vein (MHV), the issue of whether the MHV should or should not be taken with the graft or whether the MHV tributaries (V5, V8) should be reconstructed in the recipient remains to be settled. DATA SOURCES: An English-language literature search was conducted using MEDLINE (1985-2006) on right lobe living donor liver transplantation, middle hepatic vein, vein graft, hepatic venoplasty and other related subjects. RESULTS: Some institutions had proposed their policy for the management of the MHV and its tributaries. Dominancy of the hepatic vein, graft-to-recipient weight ratio, and remnant liver volume as well as the donor-to-recipient body weight ratio, the volume of the donor's right lobe to the recipient's standard liver volume and the size of MHV tributaries are the major elements for the criteria of inclusion of the MHV, while for the policy of MHV tributaries reconstruction, the proportion of congestive area and the diameter of the tributaries are the critical elements. Optimal vein grafts such as recipient's portal vein and hepatic venoplasty technique have been used to obviate hepatic congestion and venous drainage disturbance. CONCLUSIONS: Taking right liver grafts with the MHV trunk (extended right lobe grafts) or performing the MHV tributaries reconstruction in modified right lobe grafts, according to the criteria proposed by the institutions with rich experience, can solve the congestion problem of the right paramedian sector and help to improve the outcomes of the patients. The additional use of optimal vein grafts and hepatic venoplasty also can guarantee excellent venous drainage. 展开更多

Background It is difficult and challenging to reconstruct hepatic venous outflow in adult right lobe living donor liver transplantation (LDLT) without the middle hepatic vein (MHV). Excessive perfusion of the portal vein and venous outflow obstruction will lead to acute congestion of the graft, ultimately resulting in primary nonfunction. Although various reconstruction patterns have been explored in many countries, there is currently no clear consensus. In this study we describe a technique to prevent "chocking" of the graft at the outflow anastomosis with the inferior vena cava (IVC) in LDLT using right lobe graft without the MHV. Methods A retrospective analysis was conducted on clinical data from 55 recipients undergoing LDLT using right lobe grafts without the MHV or reconstruction of hepatic venous outflow. The donor's right hepatic vein (RHV) was anastomosed with a triangular opening of the recipient IVC; the inferior right hepatic vein (IRHV), if large enough, was anastomosed directly to the IVC. The great saphenous vein (GSV) was used for reconstruction of significant MHV tributaries. Results No deaths occurred in any of the donors. Of the 55 recipients, complications occurred in 6, including hepatic vein stricture (1 case), small-for-size syndrome (1), hepatic artery thrombosis (1), intestinal bleeding (1), bile leakage (1), left subphrenic abscess and pulmonary infection (1). A total of three patients died, one from small-for-size syndrome and two from multiple system organ failure. Conclusions The multiple-opening vertical anastomosis was reconstructed with hepatic vein outflow. This technique alleviates surgical risk of living donors, ensures excellent venous drainage, and prevents vascular thromboses and primary nonfunction. 展开更多

AIM: TO investigate the safety of adult-to-adult living donor liver transplantation (A-A LDLT) in both donors and recipients. METHODS: From January 2002 to July 2006, 50 cases of A-A LDLT were performed at West China Hospital, Sichuan University, consisting of 47 cases using right lobe graft without middle hepatic vein (HHV), and 3 cases using dual grafts (one case using two left lobe, 2 using one right lobe and one left lobe). The most common diagnoses were hepatitis B liver cirrosis, 30 (60%) cases; and hepatocellular carcinoma, 15 (30%) cases in adult recipients. Among them, 10 cases had the model of end-stage liver disease (HELD) with a score of more than 25. Donor screening consisted of reconstruction of the hepatic blood vessels and biliary system with 3-dimension computed tomography and volumetry of whole liver and right liver volume. Various improved surgical techniques were adopted in the procedures for both donors and recipients. RESULTS: Forty-nine right lobes and 3 left lobes (2 left lobe grafts for 1 recipient, 1 left lobe graft for 1 recipient who had received right lobe graft donated by relative living donor) were obtained from 52 living donors. The 49 right lobe grafts, without HHV, weighed 400 g-850 g (media 550 g), and the ratio of graft volume to recipient standard liver volume (GV/SLV) ranged from 31.74% to 71.68% (mean 45.35%). All donors' remnant liver volume was over 35% of the whole liver volume. There was no donor mortality. With a follow- up of 2-52 mo (media 9 too), among 50 adult recipients, complications occurred in 13 (26%) cases and 4 (8%) died postoperatively within 3 mo. Their 1-year actual survival rate was 92%.CONCLUSION: When preoperative CT volumetry shows volume of remnant liver is more than 350, the ratio of right lobe graft to recipients standard liver volume exceeding 40%, A-A LDLT using right lobe graft without MHV should be a very safe procedure for both donors and recipients, otherwise dual grafts liver transplantation should be considered. 展开更多

BACKGROUND: Because of critical organ shortage, transplant professionals have utilized living donor liver transplantation (LDLT) in recent years. We summarized our experience in adult-to-adult LDLT with grafts of right liver lobe by a modified technique. METHODS: From January 2002 to August 2005, 24 adult patients underwent living donor liver transplantation with grafts of the right liver lobe at West China Hospital, Sichuan University, China. Twenty-two patients underwent modi-Bed procedures designed to improve the reconstruction of the right hepatic vein and the tributaries of the middle hepatic vein by interposing a great saphenous vein ( GSV) graft and the anastomosis of the hepatic arteries and bile ducts. RESULTS: No severe complications and death occurred in all donors. In the first 2 patients, (patients 1 and 2), operative procedure was not modified. One patient suffered from 'small-for-size syndrome' and the other died of sepsis with progressive deterioration of graft function. In the rest 22 patients (patients 3 to 24), however, the procedure of venous reconstruction was modified, and better results were obtained. Complications occurred in 7 recipients including acute rejection (2 patients), hepatic artery thrombosis (1), bile leakage (1), intestinal bleeding (1), left sub-phrenic abscess (1), and pulmonary infection (1). One patient with pulmonary infection died of multiple organ failure (MOF). The 22 patients underwent direct anastomosis of the right hepatic vein to the inferior vena cava (IVC), 9 direct anastomosis plus the reconstruction of the right inferior hepatic vein, and 10 direct anastomosis plus the reconstruction of the tributaries of the middle hepatic vein by in-terpos-ing a GSV graft to provide sufficient venous outflow. Trifurcation of the portal vein was met in 3 patients. Venoplasty or separate anastomosis was performed. The ratio of graft to recipient body weight ranged from 0.72% to 1.17%. Among these patients, 19 had the ratio <1.0% and 4 <0.8%, and the ratio of graft weight to recipient standard liver volume was between 31.86% and 62.48%. Among these patients, 10 had the ratio <50% and 2 <40%. No 'small-for-size syndrome' occurred in the 22 recipients who were subjected to modified procedures. CONCLUSIONS: With the modified surgical techniques for the reconstruction of the hepatic vein to obtain an adequate outflow and provide a sufficient functioning liver mass, living donor liver graft in adults using the right lobe can be safe to prevent the 'small-for-size syndrome'. 展开更多
