Abstract
OBJECTIVES The aim of this retrospective study is to compare and evaluate accuracy of three different approaches of liver volume quantification in living donor transplantations. METHODS This is a single-center, retrospective study of 60 donors. The total and right lobe liver volumes were analyzed in the portal-venous phase by two independent radiologists who estimated the volumes using manual, semi-automated and automated segmentation methods. The measured right lobe liver volume was compared to the real weight of the graft after back-table examinations. RESULTS The mean estimated overall liver volume was 1164.4 ± 137.0 mL for manual, 1277.4 ± 190.4 mL for semi-automated and 1240.1 ± 108.5 mL for automated segmentation. The mean estimated right lobe volume was 762.0 ± 122.4 mL for manual, 792.9 ± 139.9 mL for semi-automated and 765.4 ± 132.7 mL for automated segmentation. The mean graft weight was 711.2 ± 142.9 g. The manual method better correlated with the graft weight (r = 0.730) in comparison with the semi-automated (r = 0.685) and the automated (r = 0.699) methods (p < 0.001). The mean error ratio in volume estimation by each application was 12.7 ± 16.6% for manual, 17.1 ± 17.3% for semi-automated, 14.7 ± 16.8% for automated methods. There was a statistically significant difference between the mean error ratio of the manual and the semi-automated segmentations (p = 0.017), and no statistically significant difference between the manual and the automated applications (p = 0.199). CONCLUSION Volume analysis application better correlates with graft weight, but there is no obvious difference between correlation coefficients of all three methods. All three modalities had an error ratio, of which the semi-automated method showed the highest value. CRITICAL RELEVANCE STATEMENT Volume analysis application was more accurate, but there is no drastic difference between correlation coefficients of all three methods.

Abstract
BACKGROUND/AIMS Biliary complications are the most common donor complication following living donor liver transplantation (LDLT). The aim of this study is to investigate the long-term outcomes of biliary complications in right lobe adult-to-adult LDLT donors, and to evaluate the efficacy of endoscopic treatment of these donors. METHODS The medical charts of right lobe donors who developed biliary complications between June 2000 and January 2008 were retrospectively reviewed. RESULTS Of 337 right lobe donors, 49 developed biliary complications, including 36 diagnosed with biliary leakage and 13 with biliary stricture. Multivariate analysis showed that biliary leakage was associated with the number of right lobe bile duct orifices. Sixteen donors, five with leakage and 11 with strictures, underwent endoscopic retrograde cholangiography (ERC). ERC was clinically successful in treating eight of the 11 strictures, one by balloon dilatation and seven by endobiliary stenting. Of the remained three, two were treated by rescue percutaneous biliary drainage and one by conservative care. Of the five patients with leakage, four were successfully treated using endobiliary stents and one with conservative care. In overall, total 35 improved with conservative treatment. All inserted stents were successfully retrieved after a median 264 days (range, 142 to 502) and there were no recurrences of stricture or leakages during a median follow-up of 10.6 years (range, 8 to 15.2). CONCLUSIONS All donors with biliary complications were successfully treated non-surgically, with most improving after endoscopic placement of endobiliary stents and none showing recurrence on long term follow-up.

Abstract
Living donor liver donation (LDLD) is an alternative to cadaveric liver donation. We aimed at identifying risk factors and developing a score for prediction of postoperative complications (POCs) after LDLD in donors. This is a retrospective cohort study in 688 donors between June 1995 and February 2014 at Hospital Sírio-Libanês and A.C. Camargo Cancer Center, in São Paulo, Brazil. Primary outcome was POC graded ≥III according to the Clavien-Dindo classification. Left lateral segment (LLS), left lobe (LL), and right lobe resections (RL) were conducted in 492 (71.4%), 109 (15.8%), and 87 (12.6%) donors, respectively. In total, 43 (6.2%) developed POCs, which were more common after RL than LLS and LL (14/87 (16.1%) versus 23/492 (4.5%) and 6/109 (5.5%), resp., p < 0.001). Multivariate analysis showed that RL resection (OR: 2.81, 95% CI: 1.32 to 3.01; p = 0.008), smoking status (OR: 3.2, 95% CI: 1.35 to 7.56; p = 0.012), and blood transfusion (OR: 3.15, 95% CI: 1.45 to 6.84; p = 0.004) were independently associated with POCs. RL resection, intraoperative blood transfusion, and smoking were associated with increased risk for POCs in donors.

Abstract
BACKGROUND Laparoscopy-assisted hepatectomy is a new minimally invasive approach for graft harvesting in living donors. Only a few liver transplant centers have introduced this surgical procedure. METHODS A prospective case-matched study was conducted on 25 consecutive donors who underwent laparoscopy-assisted donor right hepatectomy (LADRH) between July 2011 and March 2013 at our transplant center. These donors were matched 1:1 according to age, gender, and body mass index with 25 donors who underwent open donor right hepatectomy (ODRH). RESULTS LADRH was successfully performed in all 25 of the donors. Donor complications, estimated blood loss, and operative time were similar between the groups. Hospital stay and periods of analgesic use were significantly shorter in the LADRH group [7.0 ± 1.4 (LADRH) vs. 8.7 ± 2.4 (ODRH), p = 0.003, and 2.4 ± 1.0 (LADRH) vs. 3.2 ± 1.0 (ODRH), p = 0.011, respectively). The total in-hospital cost is higher with LADRH, primarily due to the additional material costs for LADRH. Finally, there were no differences in graft size, graft survival, or recipient complications between the two groups. CONCLUSION The results of this study show that LADRH is a feasible and safe procedure compared with ODRH. Although higher material costs for laparoscopic assisted procedures are inevitable, LADRH may have an advantage over ODRH by causing less pain and facilitating earlier recovery. Efforts can be made to improve the technical success of LADRH for some overweight donors.

Abstract
Biliary atresia is a rare neonatal disease of unknown etiology, where obstruction of the biliary tree causes severe cholestasis, leading to biliary cirrhosis and death in the first years of life, if the condition is left untreated. Biliary atresia is the most frequent surgical cause of cholestatic jaundice in neonates and should be evoked whenever this clinical sign is associated with pale stools and hepatomegaly. The treatment of biliary atresia is surgical and currently recommended as a sequence of, eventually, two interventions. During the first months of life a hepatoportoenterostomy (a "Kasai," modifications of which are discussed in this paper) should be performed, in order to restore the biliary flow to the intestine and lessen further damage to the liver. If this fails and/or the disease progresses towards biliary cirrhosis and life-threatening complications, then liver transplantation is indicated, for which biliary atresia represents the most frequent pediatric indication. Of importance, the earlier the Kasai is performed, the later a liver transplantation is usually needed. This warrants a great degree of awareness of biliary atresia, and the implementation of systematic screening for this life-threatening pathology.

Abstract
PURPOSE To retrospectively review anesthesia and intensive care management of 145 consented volunteers subjected to right lobe or left hepatectomy between 2003 and 2011. METHODS After local ethics committee approval, anesthetic and intensive care charts, blood transfusion requirements, laboratory data, complications and outcome of donors were analyzed. RESULTS One hundred and forty-three volunteers successfully tolerated the surgery with no blood transfusion requirements, but with a morbidity rate of (50.1%). The most frequent complication was infection (21.1%) (intraabdominal collections), followed by biliary leak (18.2%). Two donors had major complications: one had portal vein thrombosis (PVT) treated with vascular stent. This patient recovered fully. The other donor had serious intraoperative bleeding and developed postoperative PVT and liver and renal failure. He died after 12 days despite intensive treatment. He was later reported among a series of fatalities from other centers worldwide. Epidural analgesia was delivered safely (n=90) with no epidural hematoma despite significantly elevated prothrombin time (PT) and international normalization ratio (INR) postoperatively, reaching the maximum on Day 1 (16.9±2.5 s and 1.4±0.2, P<0.05 when compared with baseline). Hypophosphatemia and hypomagnesemia were frequently encountered. Total Mg and phosphorus blood levels declined significantly to 1.05±0.18 mg/dL on Day 1 and 2.3±0.83 mg/dL on Day 3 postoperatively. CONCLUSIONS Coagulation and electrolytes need to be monitored perioperatively and replaced adequately. PT and INR monitoring postoperatively is still necessary for best timing of epidural catheter removal. Live donor hepatectomy could be performed without blood transfusion. Bile leak and associated infection of abdominal collections requires further effort to better identify biliary leaks and modify the surgical closure of the bile ducts. Donor hepatectomy is definitely not a complication-free procedure; reported complication risks should be available to the volunteers during consenting.

Abstract
BACKGROUND In living-donor liver transplantation, biliary tract complications are a serious problem for recipients and donors. METHODS We applied intraoperative real-time cholangiography using a C-arm and/or C-tube drainage to reduce biliary tract complications in donor hepatectomy. From 2003 to 2010, intraoperative real-time cholangiography and C-tube drainage was applied to 39 and 19 donor cases, respectively. Fifteen donor cases had both procedures. RESULTS We confirmed the division line of the hepatic duct by visualizing a stricture on the monitor of the C-arm by pulling a thread and dissecting the proper site of the bile duct. The number of hepatic ducts of the graft to be anastomosed was 1 in 11 cases and 2 or 3 in 8 of the 19 cases without intraoperative real-time cholangiography, and it was 1 in 32 cases and 2 in 7 of the 39 cases with intraoperative real-time cholangiography. Bile leakage from the resection occurred in seven donors without, and in none of those with, C-tube drainage. CONCLUSION In living-donor liver transplantation, intraoperative real-time cholangiography enables effective determination of the precise division line of the hepatic duct. Moreover, C-tube drainage is effective for reducing bile leakage from the resected surface of the liver of donors.

Abstract
Using outcomes data from the Adult-to-Adult Living Donor Liver Transplantation Cohort Study, we performed a cost-effectiveness analysis exploring the costs and benefits of living donor liver transplantation (LDLT). A multistage Markov decision analysis model was developed with treatment, including medical management only (strategy 1), waiting list with possible deceased donor liver transplantation (DDLT; strategy 2), and waiting list with possible LDLT or DDLT (strategy 3) over 10 years. Decompensated cirrhosis with medical management offered survival of 2.0 quality-adjusted life years (QALYs) while costing an average of $65,068, waiting list with possible DDLT offered 4.4-QALY survival and a mean cost of $151,613, and waiting list with possible DDLT or LDLT offered 4.9-QALY survival and a mean cost of $208,149. Strategy 2 had an incremental cost-effectiveness ratio (ICER) of $35,976 over strategy 1, whereas strategy 3 produced an ICER of $106,788 over strategy 2. On average, strategy 3 cost $47,693 more per QALY than strategy 1. Both DDLT and LDLT were cost-effective compared to medical management of cirrhosis over our 10-year study period. The addition of LDLT to a standard waiting list DDLT program is effective at improving recipient survival and preventing waiting list deaths but at a greater cost.

Abstract
AIM: To present an analysis of the surgical and perioperative complications in a series of seventy-five right hepatectomies for living-donation (RHLD) performed in our center.
METHODS: From January 2002 to September 2007, we performed 75 RHLD, defined as removal of a portion of the liver corresponding to Couinaud segments 5-8, in order to obtain a graft for adult to adult living-related liver transplantation (ALRLT). Surgical complications were stratified according to the most recent version of the Clavien classification of postoperative surgical complications. The perioperative period was defined as within 90 d of surgery.
RESULTS: No living donor mortality was present in this series, no donor operation was aborted and no donors received any blood transfusion. Twenty-three (30.6%) living donors presented one or more episodes of complication in the perioperative period. Seven patients (9.33%) out of 75 developed biliary complications, which were the most common complications in our series.
CONCLUSION: The need to define, categorize and record complications when healthy individuals, such as living donors, undergo a major surgical procedure, such as a right hepatectomy, reflects the need for prompt and detailed reports of complications arising in this particular category of patient. Perioperative complications and post resection liver regeneration are not influenced by anatomic variations or patient demographic.

Abstract
Donor safety has been scrutinized by both the medical community and the media. Variability exists in reported donor complications and associated risk factors are ill defined. Use of administrative data can overcome the bias of single-center studies and explore variables associated with untoward events. A retrospective cohort study identifying living liver donors in two large healthcare registries yielded 433 right and left lobe donors from 13 centers between 2001 and 2005. Perioperative complications were identified using International Classification of Diseases, 9th Revision (ICD-9) coding data and classified according to the Clavien system. Logistic regression models identified factors associated with complications. There was one perioperative death (0.23%). The overall complication rate was 29.1% and major complication rate defined by a Clavien grade >or=3 was 3.5%. Center living-donor volume (OR = 0.97, 95% CI = 0.95-0.99) and the ratio of living-donors to all donors (living and deceased) (OR = 0.94, 95% CI = 0.92-0.96) were associated with a lower risk of all complications. Donor age >50 years (OR = 4.25, 95% CI = 1.22-14.87) was associated with a higher risk of major complications. Living liver donation is currently performed with a low risk of major morbidity. Use of administrative data represents an important tool to facilitate a better understanding of donor risk factors.

Abstract
A major concern in adult-to-adult living donor liver transplantation is the selection of graft type; that is, is it is better to use the right lobe with or without the middle hepatic vein (MHV)? This choice has a considerable impact on donor safety, vascular reconstruction and graft function in the recipient. To facilitate making an appropriate choice, on the basis of a preliminary study (n = 17), we herein propose a graft selection algorithm using three parameters: graft-to-recipient body weight ratio (GRWR), percentage remnant liver volume (%RLV) and estimated congestion ratio (ECR). The algorithm was evaluated with 50 consecutive cases with respect to postoperative liver function of donors and recipients and survival of recipients. Postoperative recovery was comparable between the two groups (p = NS). The overall cumulative 18-month survival rate was 86.7% for the 'with MHV graft group', and 76.1% for the gwithout MHV graft grouph (p = NS). For 41 cases (82%), graft types were chosen according to the algorithm, whereas the remaining 9 cases (18%) needed detailed discussion of donor, recipient and operative factors. In conclusion, we constructed a graft selection algorithm based on congestion volume, which will contribute to objective graft-type selection in adult-to-adult LDLT.

Abstract
The major impediment to a wider application of living donor hepatectomy, particularly of the right lobe, is its associated morbidity. The recent interest in a minimally invasive approach to liver surgery has raised the possibility of applying these techniques to living donor right lobectomy. Herein, we report the first case of a laparoscopic, hand-assisted living donor right hepatic lobectomy. We describe the technical aspects of the procedure, and discuss the rationale for considering this option. We propose that the procedure, as described, did not increase the operative risks of the procedure; instead, it decreased potential morbidity. We caution that this procedure should only be considered for select donors, and that only surgical teams familiar with both living donor hepatectomy and laparoscopic liver surgery should entertain this possibility.

Abstract
AIM: To compare the value of endoscopic retrograde cholangiography (ERC) and standard T2-weighted magnetic resonance cholangiography (MRC) in the evaluation process as adult-to-adult right lobe living donor liver transplantation (LDLTx) demands a successful outcome, and exact knowledge of the biliary tree is implicated to avoid biliary complications, postoperatively.
METHODS: After starting the LDLTx program, 18 liver transplant candidates were selected for LDLTx by a stepwise evaluation process. ERC and standard T2-weighted MRC were performed to evaluate the biliary system of the donor liver. The anatomical findings of ERC and MRC mapping were compared using the Ohkubo classification.
RESULTS: ERC allowed mapping of the whole biliary system in 15/15 (100%) cases, including 14/15 (93.3%) with biliary variants while routine MRC was only accurate in 2/13 (15.4%) cases. MRC was limited in depicting the biliary system proximal of the hepatic bifurcation. Postoperative biliary complications occurred in 2 donors and 8 recipients. Biliary complications were associated with Ohkubo type C, E or G in 6/8 recipients, and 2/3 recipients with biliary leak received a graft with multiple (≥2) bile ducts.
CONCLUSION: Pretransplant ERC is safe and superior over standard MRC for detection of biliary variations that occur with a high frequency. However, precise knowledge of biliary variants did not reduce the incidence of postoperative biliary complications.

Abstract
Adult-to-adult living donor liver transplantation (LDLT) of the right hepatic lobe has been developing into an established therapy for treating pre-terminal liver diseases. There is little experience available on the psychosocial outcome of living donors. The aim of this first qualitative case study was to investigate the patterns for impaired psychosocial outcome in donors after LDLT. Donor hepatectomies were performed in 30 donors at the Charité Berlin. Six months after surgery, the six of the 30 donors with negative moods and physical complaints in psychometric monitoring were examined. The post-operative interviews were transcribed and analysed using current qualitative research methods. These six donors (20%) reported various unspecific complaints and psychological conflicts. Sadness was expressed about organ rejection and death of the recipient. Anxieties about the recipient and their own health were verbalized. Disappointment and anger refer to the experience that they were not as fully appreciated by the medical system and their social environment as expected. The negative emotions of donors with impaired psychosocial outcome could be related to a decrease in self-esteem in the post-operative course. Adequate medical and psychological treatment opportunities for these donors should be provided.

Abstract
The purpose of this study was to ascertain the usefulness of preoperative evaluations of donors by computed tomography (CT) volumetry and CT cholangiography for prevention of unexpected liver failure and biliary complications after donor right hepatectomy for adult-to-adult living donor liver transplantation. Fifty-two donors who underwent right hepatectomy without the middle hepatic vein were enrolled in this study. The values of graft weight (GW) were significantly correlated with those of estimated graft volume (GV; P < 0.0001). GW was predicted by the following formula: GW = 155.25 + 0.658 x GV; r(2) = 0.489. CT cholangiography revealed anatomical variants of biliary structure in one-third of the donors and also clearly showed one or two small biliary branches from the caudate lobe to the right hepatic ducts or the confluence in 58% of the donors. Biliary leakage, which was treated by conservative therapy, occurred in only one donor (1.9%). No donors received homologous blood transfusion. Hyperbilirubinemia (serum total bilirubin >5 mg/dl) occurred in 5.8% of the donors during their early postoperative periods. Precise evaluations of liver remnant volume by CT volumetry and biliary variation by CT cholangiography are essential for performing safe donor hepatectomy, preventing hepatic insufficiency and minimizing the risk of biliary tract complications.

Abstract
Forty-six pediatric patients who underwent living donor liver transplantation (LDLT) using parental liver grafts for inheritable metabolic disorders (IMD) were evaluated to determine the outcomes of the surgery, decisive factors for post-transplant patient survival and the impact of using donors who were heterozygous for the particular disorder. Disorders included Wilson disease (WD, n = 21), ornithine transcarbamylase deficiency (OTCD, n = 6), tyrosinemia type I (TTI, n = 6), glycogen storage disease (GSD, n = 4), propionic acidemia (PPA, n = 3), methylmalonic acidemia (MMA, n = 2), Crigler-Najjar syndrome type I (CNSI, n = 2), bile acid synthetic defect (BASD, n = 1) and erythropoietic protoporphyria (EPP, n = 1). The post-transplant cumulative patient survival rates were 86.8 and 81.2% at 1 and 5 years, respectively. Post-transplant patient survival and recovery of the growth retardation were significantly better in the liver-oriented diseases (WD, OTCD, TTI, CNSI and BASD) than in the non-liver-oriented diseases (GSD, PPA, MMA and EPP) and pre-transplant growth retardation disadvantageously affected post-transplant outcomes. Although 40 of 46 donors were considered heterozygous for each disorder, neither mortality nor morbidity related to the heterozygosis has been observed. LDLT using parental donors can be recommended as an effective treatment for pediatric patients with IMD. In the non-liver-oriented diseases, however, satisfactory outcomes were not obtained by hepatic replacement alone.

Abstract
Sufficiently detailed information on donor safety and the liver regeneration process following right-lobe living donation has been unavailable, so we evaluated donor outcome and liver regeneration in 13 males and 14 females (39.0 +/- 14.8 years old) who provided 27 right-lobe grafts without the middle hepatic vein. Preoperative total liver volume (TLV), graft volume, and postoperative changes in residual liver volume (RLV) were measured by volumetric computed tomography. Histological steatosis of the liver was graded as none, minimal (< or =10%), and mild (11-30%). The median follow-up period was 337 days. Estimated graft volume and actual graft weight were linearly correlated (Y = 177.85 + 0.795X, R(2) = 0.812, P < 0.0001). Graft-to-recipient weight ratio was 1.08 +/- 0.19%. Four donors had postoperative complications, but they resolved in response to conservative treatment. Postoperative hospital stay was 15.2 +/- 5.5 days. Peak liver enzyme values were significantly higher in donors with mild steatosis (n = 7) than without steatosis (n = 16) (P < 0.05). Donor RLV was 40.8 +/- 6.6% of original TLV at surgery, 79.8 +/- 12.0% by 6 months, and 97.2 +/- 10.8% by 12 months. At 3 months the liver of the older donors (> or =50 years) had grown significantly more slowly than in younger donors (70.4 +/- 9.2% vs. 79.3 +/- 9.6%, P = 0.0391). In conclusion, right hepatectomy without middle hepatic vein of living donors is a safe procedure with acceptable morbidity, and the residual liver regenerated to its preoperative size by 1 year. However, meticulous care should be taken in donors with liver steatosis and aged donors.

Abstract
Numerous living donor hepatectomy are being performed safely. However, donors are still exposed to various complications including hepatic failure. We examined the donor's potential risk and morbidity depending on the type of hepatectomy: left lateral segmentectomy (group LLS, n = 30), left lobectomy (group LL, n = 15), and right lobectomy (group RL, n = 128). The charts and computerized hospital data of 173 donors from March 2000 to September 2003 were retrospectively reviewed. We analyzed liver function tests (LFT), RBC transfusion, and complications. Although the graft weight was greatest, and surgical and anesthetic times were longest in the group RL, there were no significant differences in postoperative hospital stay, RBC transfusion, and major complications among the groups. However, minor complications were significantly higher in group RL than group LLS. Postoperative prothrombin time and total bilirubin were significantly higher in the group RL than the other groups (P < 0.05). Living donor hepatectomy is relatively safe, and it is evidenced by rapid recovery of LFT and low occurrence of major complications. However, noticeable depression of LFT and frequent minor complications occur after hepatectomy, especially RL.

Abstract
Liver transplantation is accepted therapy for acute or chronic liver failure. Survival after LT has improved significantly in developed countries and this has increased the awareness of this treatment modality in the developing world. Successful LT in both children and adults have now been reported from India. Chronic liver failure secondary to cholestatic liver disease in the most frequent indication for LT, with biliary with atresia as the single commonest cause. Innovative techniques such as reduced size, splint, and living donor liver transplantation are being applied more often to decrease long waiting times and reduce associated morbidity and mortality. Early postoperative complications include primary graft failure, venous thrombosis, rejection, biliary complications and infections. Late complication includes CMV or EBV infections, side effects of immunosuppression, post transplantation lymphoproliferative disease and late biliary strictures. Most children achieve good quality of life. There are still many lessons to learn and there are future challenges such as the ever increasing problems of donor scarcity and the search for potent but less toxic immunosuppressive agents.
