Abstract
Backgrounds/Aims Challenges arise when translating pure laparoscopic donor right hepatectomy (PLDRH) results from Asian to Western donors, due to differences in body mass index (BMI). This study compares the outcomes of PLDRH and conventional open donor right hepatectomy (CDRH) in donors with BMI over 30. Methods Medical records of live liver donors (BMI > 30) undergoing right hepatectomy (2010-2021) were compared: 25 PLDRH cases vs. 19 CDRH cases. Donor and recipient demographics, operative details, and outcomes were analyzed. Results PLDRH and CDRH had similar donor and recipient characteristics. PLDRH had longer liver removal and warm ischemic times, but a shorter post-liver removal duration than CDRH. Donor complication rates were comparable, with the highest complication being grade IIIa in PLDRH, necessitating needle aspiration for biloma on postoperative day 11. Fortunately, this donor fully recovered without additional treatment. No complications exceeding Clavien-Dindo grade IIIa occurred in either group. Recipient outcomes between the groups were similar. Conclusions This study supports PLDRH as a viable option for donors with BMI over 30, challenging the notion that high BMI should deter considering PLDRH. The findings provide valuable insights into the safety and feasibility of PLDRH, encouraging further exploration of this technique in diverse donor populations.

Int J Surg 2024; 110:3203-3211. [PMID: 38477118 PMCID: PMC11175737 DOI: 10.1097/js9.0000000000001317] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/05/2023] [Accepted: 02/26/2024] [Indexed: 03/14/2024]
Abstract
BACKGROUND Although the adoption of pure laparoscopic donor hepatectomy has expanded driven by considerations of donor cosmesis and function, the criteria for selecting candidates for pure laparoscopic donor right hepatectomy (PLDRH) continue to be debated. This study aimed to delineate the distinctive characteristics of donors and recipients who underwent conventional open-donor right hepatectomy (CDRH) during the era of PLDRH. MATERIALS AND METHODS The authors conducted a retrospective review of a prospectively collected single-centre database encompassing all right hepatectomies at Seoul National University Hospital from April 2016 to December 2021, a period during which there were no absolute contraindications for PLDRH. RESULTS During the exclusive PLDRH period, there were still 63 cases of CDRH alongside 362 cases of PLDRH. The CDRH donors were older, had a lower estimated remnant liver volume, and a higher incidence of expected multiple openings in the portal vein and bile duct based on preoperative imaging compared with PLDRH donors. In the subgroup analysis, including only donors meeting two or more criteria (age ≥40 years, estimated remnant liver volume ≥35%, or multiple anticipated vessel openings), recipients in the PLDRH group exhibited significantly more early major complications ( P =0.029) compared with those in the CDRH group. CONCLUSION As PLDRH gains traction in practice, it is essential to acknowledge that specific donor conditions, such as advanced age, limited remnant liver volume, and anticipation of multiple portal or bile duct openings, may merit contemplating CDRH as a means of optimizing recipient outcomes.

[PMID: 34888346 PMCID: PMC8649712 DOI: 10.3389/fsurg.2021.771026] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/05/2021] [Accepted: 11/02/2021] [Indexed: 12/16/2022] Open
Abstract
Background: Recently, there have been several reports on pure laparoscopic donor right hepatectomy (PLDRH), but the effect of pure laparoscopy on bench surgery has not been evaluated. This study aimed to compare bench-surgery time between PLDRH and conventional donor right hepatectomy (CDRH). Methods: We retrospectively reviewed the medical records of 758 live liver donors between January 2012 and December 2019. We divided the patients into two groups: between January 2012 and September 2015, when we exclusively performed CDRH, and between March 2016 and December 2019, when PLDRH was standardized. We excluded all other types of graft donor hepatectomy, laparoscopic assisted donor hepatectomy, and cases with no recorded data. Results: In total, 267 donors were included in the PLDRH group and were compared with 247 donors in the CDRH group. Similar proportions of graft vascular variations were observed between the two groups. The mean bench-surgery time was longer in the PLDRH group than in the CDRH group (49.3 ± 19.9 vs. 39.5 ± 17.5 min; P < 0.001). Conclusion: The bench-surgery time was longer in the PLDRH group than the CDRH group, regardless of whether the vascular network was reconstructed. Expertise in bench-surgery as well as donor surgery and recipient surgery is mandatory for PLDRH to be safe and feasible.

Venous outflow reconstruction using a polytetrafluoroethylene (PTFE) graft in right lobe living donor liver transplantation: A single center study. Surgery 2021; 169:1500-1509. [PMID: 33642052 DOI: 10.1016/j.surg.2021.01.011] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/30/2020] [Revised: 01/07/2021] [Accepted: 01/09/2021] [Indexed: 12/23/2022]
Abstract
BACKGROUND Venous outflow reconstruction is very important especially in right lobe living donor liver transplantation without middle hepatic vein. Various interposition (venous or synthetic) grafts have been recommended for reconstruction of anterior sector tributaries. METHODS We aimed to describe our surgical technique and analyze anterior sector venous reconstruction using expanded polytetrafluroethylene graft. Retrospective analysis of prospectively collected data for 760 primary right lobe living donor liver transplantations performed at our institute between December 2011 and June 2018. Reconstruction of anterior sector: expanded polytetrafluroethylene (group A, n = 705) and autologous vein (group B, n = 55). RESULTS Pretransplant characteristics were comparable among both groups. Group A has significantly lower cold ischemia time (68.7 ± .3.5 minutes vs 127.8 ± 7.2 minutes; P < .001) and anhepatic time (116.3 ± 5.5 minutes vs 190.81 ± 9.35 minutes; P < .001) compared with group B. There was no difference in recovery pattern of liver functions, morbidity, and mortality between the 2 groups. One- and 6-month patency rates of interposition grafts were 97.6% and 84.4% (group A) and 96.4% and 78.1% (group B), respectively. CONCLUSION In centers with limited access to homologous or autologous vascular grafts, use of expanded polytetrafluroethylene graft for anterior sector venous outflow reconstruction in right lobe living donor liver transplantation is a viable option with excellent patency and patient outcomes.

Abstract
According to recent international consensus conferences, pure laparoscopic donor hepatectomy (PLDH), particularly right and left hepatectomies, is not yet considered a standard practice because studies remain limited. Thus, we present the outcomes of more than 500 PLDH patients, mostly receiving a right hepatectomy. To our knowledge, this is the largest study to date on PLDH. Data from all living liver donors who underwent PLDH at 5 centers in Korea until June 2018 were retrospectively analyzed. The outcomes of both donors and recipients were included. Pearson correlation analysis was used to explore the relationship between the duration of surgery and cumulative experience at each center, which reflects the learning curve. Overall, 545 PLDH cases were analyzed, including 481 right hepatectomies, 25 left hepatectomies, and 39 left lateral sectionectomies (LLS). The open conversion was necessary for 10 (1.8%) donors, and none of the donors died or experienced irreversible disability. Notably, there were 25 (4.6%) patients with major complications (higher than Clavien-Dindo grade 3). All centers except one showed a significant decrease in surgery duration as the number of cases accumulated. Regarding recipient outcomes, there were 110 cases (20.2%) of early major complications and 177 cases (32.5%) of late major complications. This study shows the early and late postoperative outcomes of 545 donors and corresponding recipients, including 481 right hepatectomies and 25 left hepatectomies, from 5 experienced centers. Although the results are comparable to those of previously reported open donor hepatectomy series, further studies are needed to consider PLDH a new standard practice.

Abstract
BACKGROUND The relationship between institutional case volume and clinical outcomes after living donor liver transplantation is not clarified. METHODS We conducted a nationwide retrospective cohort study using the database of Korean National Healthcare Insurance Service. Between January 2007 and December 2016, 7073 adult living donor liver transplantations were performed at 50 centers in Korea. Centers were categorized according to the average annual number of liver transplantations: >50, 10 to 50, and <10. RESULTS In-hospital mortality rates in the high-, medium-, and low-volume centers were 2.8%, 4.1%, and 6.7%, respectively. After adjustment, in-hospital mortality was significantly higher in low-volume centers (adjusted odds ratio, 2.287; 95% confidence interval, 1.471-3.557; P < 0.001) and medium-volume centers (adjusted odds ratio, 1.676; 95% confidence interval, 1.089-2.578; P = 0.019) compared with high-volume centers. Long-term survival for up to 9 years was better, and intensive care unit and hospital length of stay were shorter in high-volume centers. CONCLUSIONS Centers with higher case volume (>50 liver transplantations/year) had better outcomes after living donor liver transplantation, including in-hospital mortality and long-term mortality compared with centers with lower case volume (≤50 liver transplantations/year).

Transplant Proc 2019; 51:1127-1133.

Abstract
AIM The issue of performing an anastomosis of the anterior sector veins to the vena cava in living donor liver transplantation is still controversial. We aimed to research whether there was any difference in terms of complications, rejections, and graft survival between patients with and without anterior sector venous drainage to the vena cava. PATIENTS AND METHODS Patients were retrospectively investigated for demographic data and ratio of graft needed to available graft weight. Donors had volumetric calculations and middle hepatic vein anterior sector drainage documented in detail. RESULTS Seventy-three donors with middle hepatic vein drainage were included. Thirty-five had anterior sector venous drainage performed and 38 patients did not have drainage procedures performed. The incidence of general complications was higher in the group without anterior sector drainage (78.3% and P = .002). Biloma linked to bile leaks were observed in 8 patients without drainage (72.8%) and 3 patients with drainage (27.2%). Late acute rejection occurring during follow up after transplantation was identified in 28 patients (11.6%). Of these, 1 (14.3%) had anterior sector drainage and 6 (85.7%) were in the patient group without drainage (P = .067). CONCLUSION As a result of this study, for patients with grafts at the volume limit (graft weight to receiver weight ratio <0.8) and with congestion observed in the anterior sector after liver implantation and for patients with outflow problems identified on Doppler ultrasonography, anterior sector veins >5 mm should definitely be drained into the vena cava. Hence, both complication and rejection rates will reduce, and we can lengthen the graft, and thus patient, survival.

Abstract
BACKGROUND The aim of the study was to study the four week patency rates of the reconstructed neo middle hepatic vein specifically using the explant portal vein (PV) in right hemiliver live donor liver transplantation (LDLT). We hypothesized that short term patency of the neo-MHV should result in good graft and patient outcomes. METHODS Pre, intra and post operative variables were prospectively collected for 88 consecutive patients undergoing right hemiliver LDLT from January 2014 to October 2015. RESULTS Explant PV was used to reconstruct neo-MHV in 76 (86.4%, 76/88) patients. Neo MHV patency rate at 28 days with explant PV was 89.4% (59/66) and with other conduit (PTFE) was 90.9% (10/11). All occlusions were detected after 7 days. There was no impact of the patency of the neo-MHV on the incidence of early allograft dysfunction, sepsis, rejection, morbidity or mortality, despite the contribution of the anterior sector to the graft volume being more than 50% in close to two-thirds of patients. CONCLUSION The reconstructed neo-MHV has excellent short term patency rates at 4 weeks. Perhaps due to the absence of early occlusions, there was no impact on graft or patient outcomes in the study population.

Abstract
Purpose The aim of this study was to analyze survival outcomes in 1,000 consecutive liver transplantations (LTs) performed at a single institution from 1993 to April 2017. Methods The study population was divided into 2 groups based on donor type: deceased donor LT (DDLT; n = 181, 18.1%) and living donor LT (LDLT; n = 819; 81.9%), and into 3 periods based on the number of cases (first 300 cases, middle 300 cases, last 400 cases). Results Infection was the most common cause of death, accounting for 34.8% (95 of 273). Mortality due to hepatocellular carcinoma recurrence occurred most frequently between 1 and 5 years after transplantation. Mortality rate by graft rejection was highest between 5 and 10 years after transplantation. And mortality by de novo malignancy occurred most frequently after 10 years after transplantation. The patient survival rates for the entire population at 5 and 10 years were 74.7%, and 68.6%, respectively. There was no difference in survival rate between the LDLT and DDLT groups (P = 0.188). Cause of disease, disease severity, case period, and retransplantation had a significant association with patient survival (P = 0.002, P = 0.031, P = 0.003, and P = 0.024, respectively). Conclusion Surgical techniques and perioperative management for transplant patients have improved and undergone standardization. Controlling perioperative infection and managing patients with HCC as LT candidates will result in better outcomes.

Abstract
Improved survival after LT are likely to result in increased healthcare resource utilization. The pattern and risk factors of emergency department (ED) visits and unanticipated readmissions, associated cost, and predictors of healthcare resource utilization after liver transplantation (LT) patients who received LT between 2011 and 2014 were analyzed. A total of 430 LT recipients were enrolled and the 1 year all-cause mortality was 1.4%. ED visits occurred in 53% (229/430) and unanticipated readmissions occurred at least once in 58.6% (252/430) of the patients. Overall risk factors for ED visits after LT included emergency operation [OR 1.56 (95%CI 1.02-2.37), p = 0.038] and warm ischemic time of >15 minutes [OR 2.36 (95%CI 1.25-4.47), p = 0.015]. Risk factors for readmissions after LT included greater estimated blood loss during LT [OR 1.09 (95%CI 1.02-1.17), p = 0.012], warm ischemic time of >15 minutes [OR 1.98 (95%CI 1.04-3.78), p = 0.038], and hospital length of stay of >2 weeks.

Abstract
Small-for-size syndrome (SFSS) is the most significant cause of graft loss after living donor liver transplantation (LDLT), especially after left lobe (LL) LDLT in adults. The safety limit of applying LL-LDLT in adults without severe SFSS with a high rate of lethality needs to be determined. A total of 207 LL-LDLTs in adults since September 2005 were evaluated to analyze the risk factors for severe SFSS, defined as a serum total bilirubin concentration of ≥20.0 mg/dL after LDLT. Although there were no significant differences in cumulative graft survival after LDLT between medium grafts (graft volume [GV] to standard liver volume [SLV] ratio ≥ 40.0%), small grafts (35.0% ≤ GV/SLV < 40.0%), and extra small grafts (GV/SLV < 35.0%), patients with severe SFSS showed a significantly lower 5-year graft survival rate than those without (42.9% versus 94.3%, respectively; P < 0.001). Multivariate analysis for severe SFSS after LL-LDLT showed that donor age of ≥48 years (P = 0.01), Model for End-Stage Liver Disease (MELD) score of ≥ 19 (P < 0.01), and end portal venous pressure of ≥19 mm Hg (P = 0.04) were the significant and independent factors for severe SFSS after LL-LDLT. Within such high-risk subgroups of patients with a donor age of ≥48 years or MELD score of ≥ 19 before LDLT, operative blood loss volume of ≥8.0 L was a risk factor for severe SFSS. LL-LDLT in adults could be indicated and provide acceptable outcomes for the combinations of donors aged < 48 years and recipients with a MELD score of <19. Smaller grafts might yield acceptable outcomes in appropriately selected donor-recipient combinations. Liver Transplantation 22 1666-1675 2016 AASLD.

Reconstruction of hepatic venous tributary in right liver living donor liver transplantation: The importance of the inferior right hepatic vein. Liver Transpl 2016; 22:410-9. [PMID: 26684079 DOI: 10.1002/lt.24386] [Citation(s) in RCA: 16] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/15/2015] [Revised: 11/12/2015] [Accepted: 12/01/2015] [Indexed: 12/20/2022]
Abstract
Special care must be taken in hepatic vein reconstruction to avoid outflow block in living donor liver transplantation (LDLT) with a right liver graft. We have used cryopreserved homologous veins to reconstruct the right hepatic vein (RHV), middle hepatic vein (MHV), MHV tributaries (V5 and V8), and inferior right hepatic vein (IRHV). The reconstruction of V5, V8, and IRHV was based on the estimated congestive volume, calculated by the computed tomography volumetry, to secure the functional graft volume of 40% of the recipient standard liver volume. Among 262 right liver LDLT recipients, the number of reconstructed RHVs, MHVs, V5s, V8s, and IRHVs was 262, 48, 110, 111, and 147, respectively, and the overall patency was 95%, 100%, 36%, 58%, and 86%, respectively. Although the patency of the RHVs and MHVs was satisfactory, that of the V5s, V8s, and IRHVs was suboptimal. Patency of the IRHVs (86%, 126/147) was significantly better than that of both V5s (36%, 40/110) and V8s (58%, 64/111; P < 0.001). In addition, the estimated volume drained by IRHVs was significantly greater than that of V5s and V8s (IRHV, 176 ± 92 mL; V5, 105 ± 49 mL; V8, 127 ± 60 mL; P < 0.001). The patency of IRHV was significantly improved by applying the double inferior vena cava method (93%, 94/101) when compared to the direct anastomosis to vena cava (68%, 25/37; P < 0.001). The IRHV functioned as a main drainage route in cases of an obstructed RHV. In conclusion, reconstruction of the IRHV is recommended, not only to improve the functional reserve of the graft, but also to secure multiple drainage routes of the graft.

KOREAN JOURNAL OF HEPATO-BILIARY-PANCREATIC SURGERY 2015; 19:149-53. [PMID: 26693233 PMCID: PMC4683918 DOI: 10.14701/kjhbps.2015.19.4.149] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 10/04/2015] [Revised: 10/23/2015] [Accepted: 10/26/2015] [Indexed: 12/11/2022]
Abstract
BACKGROUNDS/AIMS Fatigue is common in chronic hepatitis and end-stage liver disease. However, little is known about fatigue after liver transplantation (LT). We therefore evaluated the prevalence, severity, and related factors of fatigue after LT. METHODS We retrospectively reviewed adult recipients who responded to our survey at outpatient clinics between April and May 2013. Fatigue and its severity were assessed using a questionnaire with the Fatigue Severity Scale (FSS). We defined fatigue as FSS of 4.0 or more and severe fatigue as FSS of 5.1 or more. The related factors including hepatocellular carcinoma and complications were analyzed. RESULTS A total of 93 patients were included in this study. The mean age was 54.9 (19-76) years and two-thirds were men (67.7%). Living donor LT was 77.4%. Hepatitis B related liver disease was the main underlying disease (77.4%), with hepatocellular carcinoma accompanied in 33.3%. The mean follow-up period was 66.8±43.2 (2-171) months. The mean FFS was 2.83±1.48 (1.0-6.7) overall and 5.10±0.82 (4.0-6.7) in the fatigue group. Of the 93 adult patients, fatigue was presented in 20 patients (21.5%). Among these, 9 patients (45.0%) showed severe fatigue. Even though post-LT complications tended to be greater in the fatigue group (50.0% vs. 30.1% in the non-fatigue group, p=0.098), there were no significant related factors of fatigue after LT, including hepatocellular carcinoma and major complication. CONCLUSIONS Fatigue is present in a considerable portion of recipients after LT, and almost half of them have severe fatigue. Further efforts are needed to decrease fatigue in LT recipients.

Abstract
Liver resection (LR) and liver transplantation (LT) are curative treatments for early hepatocellular carcinoma (HCC), although their performance remains debated. We compared the survival of patients with HCC conforming to the Milan criteria (MC) after LT and LR and analyzed factors affecting clinical outcomes. Between January 2006 and January 2013, 65 and 184 patients received LT and LR for HCCs fulfilling the MC, respectively. Overall survival (OS) and disease-free survival (DFS) rates were compared between the two groups. To investigate effects of liver function and living donor liver transplantation (LDLT) on survival, two subgroup analyses were performed and associations with OS and DFS were examined. We found that OS rates were higher after LT than after LR since 3 years postoperatively. DFS rates were significantly better after LT than after LR. Performance of LR, vascular invasion, and tumor multiplicity were associated with poor DFS, and factors affecting OS included the presence of vascular invasions, liver cirrhosis, and tumor multiplicity. In conclusion, despite of the effects of tumor characteristics on clinical outcomes, LT, including LDLT, should be considered the treatment of choice for patients with HCCs who met the MC. The role of LR is to identify poor prognostic factors through pathological examination.

Abstract
OBJECTIVES We present here the outcomes of our first 500 liver transplants and discuss the lessons learned during this time. MATERIALS AND METHODS We retrospectively analyzed the first 500 consecutive transplants within the listing criteria of the United Network for Organ Sharing, with recipients and donors with minimum 1-year follow-up. Patient survival and donor complications were analyzed for 31 liver transplant recipients with hepatocellular carcinoma beyond the Milan criteria who had transplant performed during the same time. RESULTS Between August 2006 and March 2013, there were 519 liver transplants performed in 500 patients (365 adult, 135 pediatric). There were 394 living-donor and 125 deceased-donor liver transplants. In addition, 31 adult liver transplants were performed in patients with hepatocellular carcinoma beyond Milan criteria (22 living-donor and 9 deceased-donor transplants). The main cause of chronic liver failure was biliary atresia in pediatric patients (30.4%) and chronic hepatitis B infection in adults (35.6%). The complication rate for primary nonfunction was 3.8%, overall biliary complications 24.0% (significantly higher after adult living-donor liver transplant, 30.3%), hepatic artery thrombosis 1.6%, portal vein thrombosis 3.0%, retransplant 3.8%, acute cellular rejection 29.6%, and bacterial infection 39.4%. Overall 1-, 3-, and 5-year patient survival rates in the first 500 consecutive transplants performed on recipients within United Network for Organ Sharing listing criteria were 87.8%, 85.0%, and 78.6%; for hepatocellular carcinoma patients beyond the Milan criteria, survival rates were 71.9%, 52.5%, and 38.2%. CONCLUSIONS In regions without a sufficient number of deceased donors, living-donor liver transplant, with its associated problems, is the only alternative to deceased-donor liver transplant. Liver transplant requires teamwork, with all players working well together for a successful outcome. The important keys to success in liver transplant include decision-making, timing, surgical skills, experience, and close follow-up.

Adult right living-donor liver transplantation with special reference to reconstruction of the middle hepatic vein. Am J Transplant 2014; 14:2777-87. [PMID: 25395154 DOI: 10.1111/ajt.12917] [Citation(s) in RCA: 32] [Impact Index Per Article: 3.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/20/2014] [Revised: 07/08/2014] [Accepted: 07/10/2014] [Indexed: 01/25/2023]
Abstract
Two hundred fifty-three consecutive living-donor liver transplant recipients with a right liver graft (RLG) were divided into three groups: an extended right liver graft (ERLG) group (n = 47) in which the middle hepatic vein (MHV) trunk was included in the graft, a modified right liver graft (MRLG) group (n = 114) in which the MHV tributaries were reconstructed with cryopreserved homologous veins and a simple RLG group (n = 92) in which the MHV tributaries were sacrificed. The volume of the anterior sector was significantly impaired in the RLG group compared to the other two groups, whereas the volume of the posterior sector was significantly improved in the RLG group, indicating that the impaired anterior sector regeneration by MHV deprivation was compensated by the posterior sector regeneration. The regeneration rate of the anterior sector was highest in the ERLG group (92%), moderate in the MRLG group (71%) and lowest in the RLG group (52%). The whole graft regeneration rate of the ERLG group was significantly higher than that of the other two groups. Poor regeneration, however, was not correlated with delayed functional recovery or long-term outcome. Short-term, the patency of reconstructed MHV tributaries was over 90%, but occlusion occurred frequently over the long-term, especially in V5.

Abstract
Background/Aims The dose of mycophenolate mofetil (MMF) has been reduced in Asia due to side effects associated with the conventional fixed dose of 2-3 g/day. We aimed to determine the pharmacokinetics of a reduced dose of MMF and to validate its feasibility in combination with tacrolimus in living-donor liver transplantation (LDLT). Methods Two sequential studies were performed in adult LDLT between October 2009 and 2011. First, we performed a prospective pharmacokinetic study in 15 recipients. We measured the area under the curve from 0 to 12 hours (AUC0-12) for mycophenolic acid at postoperative days 7 and 14, and we performed a protocol biopsy before discharge. Second, among 215 recipients, we reviewed 74 patients who were initially administered a reduced dose of MMF (1.0 g/day) with tacrolimus (trough, 8-12 ng/mL during the first month, and 5-8 ng/mL thereafter), with a 1-year follow-up. We performed protocol biopsies at 2 weeks and 1 year post-LDLT. Results In the first part of study, AUC0-12 was less than 30 mgh/L in 93.3% of cases. In the second, validating study, 41.9% of the recipients needed dose reduction or cessation due to side effects within the first year after LDLT. At 12 months post-LDLT, 17.6% of the recipients were administered a lower dose of MMF (0.5 g/day), and 16.2% needed permanent cessation due to side effects. The 1- and 12-month rejection-free survival rates were 98.6% and 97.3%, respectively. Conclusions A reduced dose of MMF was associated with low blood levels compared to the existing recommended therapeutic range. However, reducing the dose of MMF combined with a low level of tacrolimus was feasible clinically, with an excellent short-term outcome in LDLT.
