Adult-to-adult living donor liver transplantation (LDLT) using right hemi-liver has become a promising treatment modality for patients with end-stage liver disease. The rapid adoption of the procedure has been triggered mainly by the significant gap between available cadaver grafts and the number of patients on the waiting list for liver transplant. Since the arguments against LDLT focus only on the safety of the donor, the demonstration that the donor operation can be performed with minimal morbidity will make it more ethically acceptable. The advantages of LDLT are the possibility of performing an elective operation, access to a graft in best condition, and the possibility of lowering the likelihood of death while waiting for a suitable organ. As well as the standard indications for liver transplantation, LDLT opens up the possibility of treatment of patients with borderline indications. Further improvement of surgical and medical technology, careful long-term follow-up of donors and recipients, and profound analysis of socioeconomic aspects are essential issues for the transplantation community.
OBJECTIVE: To present an institutional experience with the use of right liver grafts in adult patients and to assess the practicability and efficacy of this procedure by analyzing the results. SUMMARY BACKGROUND DATA: Living donor liver transplantation (LDLT) for the pediatric population has gained worldwide acceptance. In the past few years, LDLT has also become feasible for adult patients due to technical evolution in hepatobiliary surgery and increased experience with reduced-size and split-liver transplants. Nevertheless, some graft losses remain unexplained and are possibly due to unrecognized venous outflow problems. METHODS: From April 1998 to September 2002, we performed 74 right LDLTs (segments 5-8). The 74 donors were selected from 474 candidates according to standard protocol. The median age of the donors was 35 years (range 18-58 years) and 51 years (range 18-64 years) in recipients. Standard and extended indications for transplantation were considered. Over the period reported, technical modifications in the bile duct anastomosis (duct-to-duct, end-to-end, or end-to-side) and a new graft implantation technique that provides maximized venous outflow, leading to outcome improvement, were developed. RESULTS: 64.9% of patients had liver cirrhosis and 35.1% had malignancy. While 44 donors (59.5%) presented an uneventful postoperative course, 27% minor (pleural effusion, pneumonia, venous thrombosis, wound infection, incisional hernia) and 13.5% major (biliary leakage, death of a donor due to unrecognized hereditary liver disease, and consecutive liver insufficiency) complications were documented. In recipients, 23% biliary complications and 6.8% hepatic artery thrombosis occurred. The overall patient and graft survival rate after 1 year was 79.4% and 75.3%, respectively. In cases with extended indication, the patient survival rate was 74% and the graft survival rate 68% at 12 months. Using technical modifications in the last 10 recipients, including 2 critically decompensated cirrhotics, the survival rate was 100% at a median follow-up of 3.5 months. CONCLUSIONS: In our transplant program, living donor liver transplantation has become a standard option in the adult patient population. The critical issue of this procedure is donor morbidity. Technical improvements in the harvesting and implantation of right grafts can also offer hope to patients with challenging forms of end-stage liver disease or malignant liver tumors.
BACKGROUND: In the past, follow-up surveys for living-related liver transplantation (LRLT) mainly focused on the medical outcome of recipients and donors. In this survey the prevalence of personal, familial, or economic problems of the donors and changes of quality of life after donation were studied. METHODS: Questionnaires were sent to 24 donors after right hepatectomy for LRLT (response 92%). The modified EUROTOLD (European Multicenter Study of Transplantation Using Living Donors) questionnaire was used to inquire about the decision-making process, family problems, and economic problems related to the donation. Global quality of life was measured with the SF-36 Health Survey. RESULTS: For most donors the decision to donate was easy or not very difficult (21/22) and was made spontaneously (17/22). The amount of information about the risks of LRLT was limited at the time of decision but increased remarkably immediately before the operation. In 28%, family conflicts occurred (5/22). Retrospectively, all but two donors (91%) would donate again. On average, donors started working after 9 (+/-3.7) weeks and felt fully recovered after 13 (+/-7.3) weeks. Adverse financial affects were experienced by 41% of the donors (9/22) because of the donation, and four of those received a compensation. Importantly, quality of life did not differ between donors and nondonors. CONCLUSION: Donors viewed LRLT positively. Quality of life after donation did not change. However, donors had a prolonged period of physical rehabilitation, and 41% experienced financial disadvantages.
BACKGROUND AND AIMS: Bile duct complications are the modern Achilles' heel of adult-to-adult living donor liver transplantation. A duct-to-duct anastomosis is currently performed in the presence of single graft ducts, while cholangiojejunostomy is used to drain multiple ducts. Our aim is to describe the feasibility of duct-to-duct anastomoses independent of the presence of one or multiple graft bile ducts. METHODS: The probe technique for right bile duct dissection in donors and a proximal hilar bile duct division in recipients are illustrated. The BARIGA LDLT (biliary anastomosis in right graft for adult living donor liver transplantation recipients) with end-to-side or end-to-end hepatico-hepaticostomy was used in five recipients of right grafts (segments 5-8). RESULTS: All donors and recipients are doing well; all grafts are functional at 13 months. Duct-to-duct anastomoses to single, double, or triple graft ducts have been performed. Two early anastomotic stenoses at 5 and 10 weeks were successfully treated endoscopically. CONCLUSION: The duct-to-duct anastomosis represents a valid alternative to the standard hepaticojejunostomy for right living donor liver grafts. Using this method, biliary complications can be treated endoscopically. End-to-side or end-to-end BARIGA LDLT has the potential to become a standard method in segmental transplantation, including split liver.
Adult-to-adult living donor liver transplantation (LDLT) for patients with decompensated end-stage liver disease (DELD) is controversial. Nevertheless, these patients are most in need of a timely liver transplant. We present the results of 7 patients who underwent transplantation with this procedure and discuss the rationale for its possible broader application. Seven of 51 patients who underwent right LDLT (segments 5 to 8) between August 1998 and April 2001 had DELD, defined as Child-Pugh-Turcotte score greater than 13 or Model for End-Stage Liver Disease score greater than 30. All patients also were listed for cadaveric liver transplantation. Mean age of the 7 transplant recipients was 54 years (range, 44 to 63 years). Three patients had ethyltoxic cirrhosis; 2 patients, hepatitis C; 1 patient, hepatitis B; and 1 patient, autoimmune hepatitis cirrhosis. The average intensive care unit stay was 23 days (range, 3 to 88 days), and average hospital stay was 77 days (range, 27 to 132 days). Three patients are alive 31, 21, and 17 months after LDLT. At a mean follow-up of 15.1 +/- 10 months, patient and graft survival rates are 43%. Four transplant recipients died day 30, 60, 117, and 180 after transplantation. Three of the seven donors (43%) experienced a complication. At present, all donors are well and have returned to their normal activities. No donors had regrets about the procedure, and all donors stated that they would donate again if presented with the same decision. In conclusion, with the lack of other therapeutic options, LDLT represents a timely and effective alternative to cadaveric liver transplantation. Better outcome is foreseeable with a decrease in posttransplantation complications and more experience in predicting survival of these critical patients.

Bile duct injury is a severe and potentially life-threatening complication of laparoscopic cholecystectomy. Several series have described a 0.5% to 1.4% incidence of bile duct injuries during laparoscopic cholecystectomy. The aim of this study was to report on an institutional experience with the management of complex bile duct injuries and outcome after surgical repair. Data were collected prospectively from 40 patients with bile duct injuries referred for surgical treatment to our center between April 1998 and December 2003. Prior to referral, 35 patients (87.5%) underwent attempts at surgical reconstruction at the primary hospital. In 77.5% of the patients, complex type E1 or type E2 BDI was found. Concomitant with bile duct injury, seven patients had vascular injuries. Roux-en-Y hepaticojejunostomy was carried out in 33 patients. In two patients, Roux-en-Y hepaticojejunostomy and vascular reconstruction were necessary. Five patients, one with primary nondiagnosed Klatskin tumor, required right hepatectomy. Two patients, both with bile duct injuries and vascular damage, died postoperatively. Because of progressive liver insufficiency, one of them was listed for high-urgency liver transplantation but died prior to intervention. At the median follow-up of 589 days, 82.5% of the patients are in excellent general condition. Seven patients have signs of chronic cholangitis. Major bile duct injuries remain a significant cause of morbidity and even death after laparoscopic cholecystectomy. Because they present a considerable surgical challenge, early referral to an experienced hepatobiliary center is recommended.
BACKGROUND/AIMS: Adequate venous outflow is a prerequisite for successful live donor liver transplantation. Several techniques of liver transection have been established in both transplant and non-transplant hepatic surgery. The purpose of our study was to define and compare anatomical and physiological characteristics of venous drainage in the three most common types of liver transection techniques (Malagó, Cantlie, Pringle) encountered in live donor liver transplantation METHODOLOGY: Volumes of both graft and remnant livers as well as individual hepatic vein territories were calculated by means of virtual 3-dimensional reconstructions of computed tomography images obtained from 55 potential live liver donors using the software HepaVision (MeVis, Germany). Belonging to the middle hepatic vein (MHV) was assigned according to the largest territorial volume on either right or left hemilivers. Livers from all potential donors were subject to virtual splitting (n=55). Findings were subsequently confirmed intraoperatively in those who underwent donor resection (n=27). RESULTS: There were no statistically significant differences in hemiliver-volumes among the three types of liver partition. There was a predominance of MHV belonging to the right hemiliver: Malagó n=45 (82%) vs. Cantlie n=44 (80%) vs. Pringle n=44 (80%). Dominant right MHV hemiterritory showed a mean volume of 284-296 mL, accounting for 59-61% of total MHV volume. There were no significant differences among the three types of liver partition evaluated. CONCLUSIONS: Our results demonstrate the reliability of virtual 3-dimensional reconstructions based on standard anatomical landmarks for both surgical planning and graft volume calculations. We believe our technique will help prevent small-for-size grafting and liver insufficiency resulting from inaccurate volumetric calculations. Our findings also support the observation that improved venous outflow might be achieved by including the MHV with the right liver graft without disadvantaging the left liver remnant. It is our hope that all these findings will translate into enhanced donor and recipient safety.
BACKGROUND/AIMS: To determine resectability rates in patients with hepatocellular carcinoma (HCC) evaluated for surgical therapy. Liver resection constitutes a potentially curative treatment for HCC. However, because of the co-existing cirrhosis or the late diagnosis, only a percentage of the patients evaluated can undergo surgery. METHODOLOGY: We evaluated 333 patients with HCC admitted to our center with the intent to treat by means of tumor resection during a 6-year time period. RESULTS: Surgical resection with curative intent was undertaken in 116 patients (35%). In our series, resectability rates were significantly higher in patients with solitary HCCs (p<0.001), unilobar tumor distribution (p=0.03), and no cirrhosis (p <0.001). Transarterial chemoembolization (TACE) was the most frequent approach for nonresectable cases (18% of patients). A systematic literature review was performed in order to estimate resectability rates at other hepatobiliary centers offering multimodal treatment approaches to HCC. Results showed an overall resectability rate of 30%, with 1808 resections reported in 6108 cases. Resectability rates were significantly higher in Japanese and Eastern series when compared to American and Western studies respectively (p<0.001). CONCLUSIONS: Treatment strategies for HCC require a multidisciplinary comprehensive approach encompassing surgeons, hepatologists, radiologists, and oncologists. Surgical resection was possible in only 35% and 30% of patients with HCC evaluated for surgical therapy in our series and in the world literature, respectively. TACE was the primary treatment modality for non-resectable cases. A "no therapy" option was chosen in 21% of cases worldwide.
BACKGROUND/AIMS: Liver transplantation (LTx) is recognized as the treatment of choice for small hepatocellular carcinomas (HCC) in patients with end-stage liver failure. However, because of limited organ availability, not all those who qualify can benefit from full-size LTx. METHODOLOGY: Over a 28-month period, we transplanted 6 deceased donor split liver allografts in stable recipients with HCC and cirrhosis. RESULTS: There were 5 men and one woman with a median age of 60 years. Median waiting time to LTx was 82 days. Extended right split grafts (segments I, IV-VIII) were transplanted in 5 patients. One patient received a right split graft. In situ harvesting was performed in 4 instances and ex situ in the remaining 2. Median cold ischemia time was 10 hours. Primary non-function was not observed. Median intensive care unit stay was 4 days. There were neither vascular nor biliary complications. The postoperative course was uneventful in half of the patients. Two patients were re-operated because of an abscess caused by a liver necrosis in the marginal zone of segment IV. One patient died for reasons unrelated to liver function or to the surgical intervention. The remaining 5 patients are alive after a median follow-up of 20 months. CONCLUSIONS: Deceased donor split LTx constitutes an additional option for patients with HCC and cirrhosis. The potential risks of using "split livers" as well as the potential benefits of transplanting patients unlikely to survive the waiting list period must be evaluated on an individual basis.
BACKGROUND/AIMS: Adequate venous drainage is essential to prevent parenchyma congestion in graft and remnant livers after adult live donor liver transplantation (ALDLT). The areas particularly prone to congestion are the right and left medial sectors. The purpose of our study was to evaluate two types of liver transection techniques (Cantlie, Malagó) frequently encountered in ALDLT and to determine their resulting anatomical and functional liver graft volumes. METHODOLOGY: Livers from 58 potential live liver donors were subject to a virtual 3-dimensional liver partition for right graft hepatectomy. Anatomical (post-transectional) volumes of both right graft and left remnant livers in either liver partition group were initially estimated and corresponding anatomic-GVBWR for the graft hemiliver was calculated. Additionally the potential venous drainage impairment in the medial area of the graft, which was influenced by the two different transection planes, was estimated giving the baseline for the calculation of the functional-GVBWR of the graft. RESULTS: Computer analysis showed no statistically significant differences in the anatomical volumetric parameters between the two potential types of liver partition. However, virtual liver partition following the Cantlie line showed significant decrease of functional volumetric parameters for right liver graft, due to incidental detachment of the right-sided tributaries of middle hepatic vein. CONCLUSIONS: Image-based computer assistance allows for areas at risk for devascularization or venous congestion to be identified and calculated before parenchyma transection in ALDLT. According to the results of this study, minimal modifications of the transection line can provide significant increases in functional volumetric parameters by avoiding venous congestion in the marginal zone of the graft, drained by the middle hepatic vein.
