Metallic Stents for Hepatic Venous Outflow Obstruction After Living-Donor Liver Transplantation and their Therapeutic Effects. Transplant Proc 2024; 56:125-134. [PMID: 38177046 DOI: 10.1016/j.transproceed.2023.11.009] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/16/2023] [Revised: 10/26/2023] [Accepted: 11/30/2023] [Indexed: 01/06/2024]
Abstract
BACKGROUND Living-donor liver transplantation (LDLT) is established as a standard therapy for end-stage liver disease; however, vessel reconstruction is more demanding due to the short length and small size of the available structures compared with deceased-donor whole liver transplantation. Interventional radiology (IR) has become the first-line treatment for vascular complications after LDLT. Hepatic venous outflow obstruction (HVOO) is a life-threatening complication after LDLT. The aim of this study of 592 adult-to-adult LDLT cases was to investigate the safety and efficacy of stent implantation for HVOO after LDLT. METHODS Records of patients who developed HVOO requiring any treatment were collected with special reference to the metallic stent implantation. There were 232 left-side grafts and 360 right-side grafts. Sixteen cases developed HVOO after LDLT with an incidence rate of 2.7%, 5 with a left liver graft (2%), and 11 with a right-side graft (3%). The IR was attempted for 14 cases; among those, 8 cases were treated by stent implantation. RESULTS The technical success rate of the initial stent implantation was 100%. The pressure gradient at the stenotic site significantly improved from 12.2 (range, 10.9-20.4 cm H2O) to 3.9 cm H2O (range, 1.4-8.2 cm H2O; P = .03). The volume of the congested graft liver decreased significantly from 1448 (range, 788-2170 mL) to 1265 mL (range, 748-1665 mL; P = .01), and the serum albumin level improved significantly from 3.3 (range, 1.7-3.7 g/dL) to 3.7 g/dL (range, 2.9-4.1 g/dL; P = .02). No procedure-related complication was noted, and the long-term stent patency was 100%. CONCLUSION Metallic stent implantation for stenotic venous anastomosis after LDLT is a safe and effective treatment.

Eur J Radiol 2023; 168:111016. [PMID: 37742371 DOI: 10.1016/j.ejrad.2023.111016] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/20/2022] [Revised: 07/13/2023] [Accepted: 07/26/2023] [Indexed: 09/26/2023]
Abstract
PURPOSE The morphometry of the hepatic portal vein is of clinical importance, particularly in pre-operative assessments, surgical management, and diagnoses of liver conditions. This systematic review and meta-analysis aimed to characterize the morphometry of the normal portal vein in both pediatric and adult patients. METHODS The study, conducted using the PRISMA guidelines and registered with PROSPERO, utilized the MEDLINE, EMBASE, SCOPUS and Web of Science databases up to May 2020, and updated to May 2023. All studies reporting extractable data on diameter, length, and cross-sectional area (CSA) of the main, left, and right portal veins (PV, LPV, RPV, respectively) were included. The AQUA Tool was used to assess the quality of the included studies. Data analysis included subgroup analyses based on geographical location, sex, age, and imaging modality. RESULTS A total of 122 studies with 11,637 subjects were eligible for inclusion. Overall, the pooled mean diameter of the PV (PVD) was 10.09 mm (95% CI: 9.56-10.62). Significant differences in diameter were found between pediatric (6.60 mm; 95% CI: 5.38-7.82) and adult (10.72 mm; 95% CI: 10.25-11.19) subjects. Additionally, there was a significantly larger PVD measurement from computed tomography (CT) than other imaging modalities: CT, 13.28 mm (95% CI: 11.71-14.84); magnetic resonance imaging (MRI), 10.50 mm (95% CI: 9.35-11.66) and ultrasound (US), 9.81 mm (95% CI: 9.47-10.16). The mean diameters of the LPV and RPV were 8.27 mm (95% CI: 6.78-9.77) and 8.33 mm (95% CI: 6.70-9.95), respectively. Mean PV length in adults is 48.63 mm (95% CI: 35.63-61.64). Mean CSA of the PV was 1.09 cm2. CONCLUSIONS The study obtained aim to improve the understanding of portal vein anatomy, especially with relevance to surgical interventions of the liver in both pediatric and adult patients. Measurements from ultrasound imaging closely approximates the generated pooled PVD mean for pediatric and adult patients. CT imaging, however, significantly exceeded the established 13 mm threshold for adults. For pediatric patients, a threshold of 8 mm is proposed as a diagnostic upper limit for a normal PVD. Although not significant, the PVD decreased from the portal confluence towards its bifurcation.

[PMID: 36230776 PMCID: PMC9564260 DOI: 10.3390/cancers14194853] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/26/2022] [Revised: 09/29/2022] [Accepted: 09/30/2022] [Indexed: 11/16/2022] Open
Abstract
Background: This study aims to evaluate sinistral portal hypertension (SPH) development and its clinical impact on the long-term outcomes of patients with pancreatic cancer who underwent surgical resection with splenic vein (SV) ligation. Methods: Data from 94 consecutive patients who underwent pancreatoduodenectomy (PD) with vascular resection for pancreatic cancer from 2008 to 2019 were retrospectively collected. The patients were divided into two groups according to whether the SV was preserved or ligated during the surgery. Their computed tomography images were serially reviewed (preoperative, 6-, 12-, and 24-months postoperative) with clinical parameters. The degree of variceal formation (variceal score) and splenomegaly were assessed, and the oncologic outcomes were compared between the two groups. Variceal score in the SV ligation group was significantly higher than that in the SV saving group at the same postoperative periods (SV saving vs. ligation: 12 months, 0.9 ± 1.3 vs. 3.5 ± 2.2, p < 0.001; 24 months, 1.4 ± 1.8 vs. 4.0 ± 3.4, p = 0.009). Clinically relevant variceal bleeding was noted in one patient from the SV ligation group (SV saving vs. ligation: 0.0% vs. 3.1%, p = 0.953). In survival analysis, there was no significant difference between the two groups (DFS; SV saving vs. ligation: 13.0 (11.1−14.9) months vs. 13.0 (10.4−15.6) months, p = 0.969, OS; SV saving vs. ligation: 35.0 (19.9−50.1) months vs. 27.0 (11.6−42.4) months, p = 0.417). Although SV ligation induced SPH during PD for pancreatic cancer, it did not lead to clinically significant long-term complications. In addition, it did not impact the long-term survival of patients with resected pancreatic head cancer.

Abstract
OBJECTIVES Although advanced age is no longer considered an absolute contraindication for liver transplant, transplant in elderly patients with comorbid diseases remains debatable because of high risks with surgery. Here, we report patient outcomes in this population. MATERIALS AND METHODS We retrospectively reviewed medical records of 276 liver transplant recipients, grouped by age. Group 1 (≤59 years old) consisted of 247 recipients, and group 2 (≥60 years old) consisted of 29 recipients. Reviewed data included age, sex, cause of liver disease, presence of hepatocellular carcinoma, Child-Pugh and Model for End-Stage Liver Disease scores, survival, and posttransplant complications. RESULTS In both groups, most patients (n = 108) required liver transplant for hepatitis B virus. Mean age was 40 ± 12.3 and 63 ± 2.3 years in groups 1 and 2, respectively, with more men than women in both group 1 (71.7% vs 28.3%) and group 2 (75.9% vs 24.1%). No significant differences were shown between groups for patient characteristics, except group 1 had significantly higher Model for End-Stage Liver Disease score. Group 1 mean survival time was 10.2 ± 0.6 years, with patient survival rates at 1, 5, 10, and 15 years of 65.5%, 53%, 46.3%, and 40%, respectively. In group 2, respective results were 10.6 ± 1.3 years and 75.9%, 68.6%, 61%, and 48.8% (no significant difference vs group 1). CONCLUSIONS Liver transplant recipients >60 years of age had survival rates, acute rejection rates, and complications similar to younger recipients. Liver transplant should not be withheld from older recipients on the basis of age alone. However, comprehensive screening for comorbidities should be performed.

Abstract
The orifice size of the LHV trunk in LLS grafts is often too small for direct anastomosis. Several methods were developed to enlarge the graft and recipient hepatic vein orifices. This study described our surgical techniques to secure hepatic vein reconstruction in infant recipients and analyzed the patency outcomes. Twelve infants undergoing pediatric LDLT were selected during 2-year study period between January 2018 and December 2019. Surgical techniques and vascular complications of graft hepatic vein outflow were analyzed. The mean recipient age was 12.5 ± 4.5 months; mean body weight was 9.4 ± 1.0 Kg; and mean graft-recipient weight ratio was 2.8 ± 0.6%. Primary diseases were biliary atresia in six patients, metabolic diseases in two, hepatoblastoma in two, and acute liver failure in two. Eight LLS grafts were recovered through an open method, and four LLS grafts were recovered through a laparoscopic method. A small superficial LHV branch was present in five of 12 LLS grafts, which was opened to widen the graft hepatic vein orifice. Incision-and-patch venoplasty was performed in 10, unification venoplasty in 1 and no venoplasty in 1. All four LLS grafts recovered through a laparoscopic approach required circumferential vein patch because of very short hepatic vein stump. No patient experienced graft hepatic vein-associated vascular complications during the follow-up period of 19.3 ± 9.3 months. Our surgical techniques with incision-and-patch venoplasty for LLS grafts is beneficial to reduce the risk of hepatic vein outflow obstruction in recipients receiving LLS grafts.

Abstract
Laparoscopically harvested left lateral section (LLS) grafts have drawbacks regarding the size of the graft left hepatic vein (LHV) orifice although they have the merit of cosmetics concerning the donor’s wound. We present a case of pediatric living donor liver transplantation (LDLT) using a laparoscopically harvested LLS graft and describe the refined surgical techniques for graft LHV venoplasty with a circumferential vein patch. The patient was a 46-month-old boy with marked growth retardation who was diagnosed with progressive familial intrahepatic cholestasis type 2. The donor was his 25-year-old mother. The LLS graft weighed 285 g. A circumferential patch of external iliac vein homograft was attached to the graft LHV orifice after incisions were made at the medial wall of the LHV trunk and superficial LHV branch, which made the graft LHV orifice much larger. The recipient’s hepatic vein orifice was also enlarged by unifying the three hepatic vein orifices. Other surgical procedures followed the standard LDLT operation. This patient recovered uneventfully and has been doing well for 1 year. In conclusion, our incision-and-patch venoplasty to enlarge the graft outflow vein orifice was beneficial for reducing the risk of hepatic vein outflow obstruction in LDLT using a laparoscopically harvested LLS graft.

Abstract
Orifice size of the left hepatic vein trunk (LHV) in left lateral segment (LLS) grafts is often too small to perform direct anastomosis. A small superficial branch of LHV is encountered in approximately 30% of LLS grafts. Unification venoplasty of the LHV trunk and its superficial vein branch makes the orifice size of LLS outflow vein larger than the original size. We present refined surgical techniques for LHV unification venoplasty with a superficial LHV branch. The patient was a 5-month-old 9 kg-weighing girl with biliary atresia. Her general condition deteriorated, but there was low possibility of deceased donor liver allocation, thus living donor liver transplantation was performed using her mother's LLS. The graft hepatic vein was widened through unification venoplasty of LHV and its superficial branch. Recipient hepatic vein orifice was widened through unification of three hepatic veins. The graft and recipient hepatic vein orifices were well matched in size, and they were anastomosed with 5-0 continuous sutures. The portal vein was reconstructed with interposition of cold-preserved external iliac vein homograft. The graft left hepatic artery was reconstructed using the recipient right hepatic artery and hepaticojejunostomy was performed. This patient recovered uneventfully and is doing well for 3 months to date. The unification venoplasty with LHV trunk and its superficial vein branch makes the size of LLS outflow vein definitely larger than the original size, thus it can be a useful technical option to reduce the risk of hepatic vein outflow obstruction in pediatric liver transplantation using a LLS graft.

Abstract
OBJECTIVES An incisional hernia seriously burdens the quality of life after liver transplant. The incidence of incisional hernia after liver transplant is reported to be 4% to 20%. Here, we evaluated incisional hernias that occurred after adult liver transplant and incisional hernias intentionally made in infant liver transplant procedures. MATERIALS AND METHODS Between December 1988 and May 2016, we performed 536 liver transplant procedures in 515 patients. Demographic features, surgical outcomes, and predisposing factors were evaluated. RESULTS Of 452 liver transplant patients included, incisional hernias were diagnosed in 29 patients (6.4%; 7 pediatric, 22 adult). Most were males (77%) with Child-Pugh score C cirrhosis (62%), moderate/severe ascites (81%), and serum albumin levels <3.5 g/L (86%). Incisional hernia developed in 16 of 51 patients (31%) with wound infection. Twelve incisional hernias were seen in 40 recipients (30%) with body mass index ≥30 kg/m2. Eight of 45 patients (18%) with repeated surgery had incisional hernias. Five of 22 adult incisional hernias (23%) had primary fascia repair, and 17 (77%) were repaired with Prolene mesh graft (3 sublay, 14 onlay). No other complications and no hernia recurrence were shown during follow-up (range, 8-138 mo). Of 7 pediatric liver transplant patients with intentionally made incisional hernias during liver transplant, 5 patients had primary fascia repair and 2 patients had onlay mesh repair. No complications or recurrence were shown during follow-up (range, 12-60 mo). CONCLUSIONS Repeated surgery, postoperative wound infection, and obesity were found to be predisposing risk factors for incisional hernia development after liver transplant in adults. Abdomen closure in infant liver transplant with large-for-size grafts is a different area of discussion. Here, we suggest that an intentionally made incisional hernia with staged closure of the abdomen is safe and effective for graft and patient survival.

Abstract
As advances in surgical techniques and postoperative care continue to improve outcomes, the use of solid organ transplants as a treatment for end-stage organ disease is increasing. With the growing population of transplant patients, there is an increasing need for radiologic diagnosis and minimally invasive procedures for the management of posttransplant complications. Typical complications may be vascular or nonvascular. Vascular complications include arterial stenosis, graft thrombosis, and development of fistulae. Common nonvascular complications consist of leaks, abscess formation, and stricture development. The use of interventional radiology in the management of these problems has led to better graft survival and lower patient morbidity and mortality. An understanding of surgical techniques, postoperative anatomy, radiologic findings, and management options for complications is critical for proficient management of complex transplant cases. This article reviews these factors for kidney, liver, pancreas, islet cell, lung, and small bowel transplants.

Abstract
Both, autologous and allogeneic hematopoietic stem cell transplantation (HSCT) can be used to cure or ameliorate a variety of malignant and non-malignant diseases. The rationale behind this strategy is based on the concept of immunoablation using high-dose chemotherapy, with subsequent regeneration of naive T-lymphocytes derived from reinfused hematopoietic progenitor cells. In addition, the use of HSCT allows for the administration of high-dose chemotherapy (whether or not combined with immunomodulating agents such as antithymocyte globulin) resulting in a prompt remission in therapy-refractory patients. This review gives an update of the major areas of successful uses of HSCT in non-malignant gastrointestinal disorders. A Medline search has been conducted and all relevant published data were analyzed. HSCT has been proved successful in treating refractory Crohn’s disease (CD). Patients with refractory celiac disease type II and a high risk of developing enteropathy associated T-cell lymphoma have shown promising improvement. Data concerning HSCT and mesenchymal SCT in end-stage chronic liver diseases are encouraging. In refractory autoimmune gastrointestinal diseases high-dose chemotherapy followed by HSCT seems feasible and safe and might result in long-term improvement of disease activity. Mesenchymal SCT for a selected group of CD is promising and may represent a significant therapeutic alternative in treating fistulas in CD.

Abstract
Although rare, major congenital defects of the hepatic veins are detectable at autopsy, advanced, noninvasive imaging techniques such as Doppler ultrasonography and multislice computed tomography can accurately define these anomalies. One of these anomalies is congenital absence of the main right hepatic vein. We present a 21-year-old woman living-liver donor candidate with congenital absence of the right hepatic vein who underwent an extended right donor hepatectomy. She was tested for transplant compatibility with her 45-year-old brother, who had chronic liver failure secondary to hepatitis B. Multislice computed tomography revealed an absence of the right hepatic vein, and the right hepatic lobe was drained by 4 inferior hepatic veins with diameters ranging from 4 to 8.4 mm. An extended right-donor hepatectomy was performed. A common-large opening drainage reconstruction model that included all of the inferior hepatic veins and middle hepatic vein was created using the saphenous vein and an aortic homograft. There were no postoperative complications related to hepatic venous drainage thanks to the common-large opening model. We demonstrate that a right donor hepatectomy is feasible in congenital absence of the right hepatic vein solving the drainage problem using common-large opening reconstruction technique.

Abstract
PURPOSE Portal vein stenosis is a relatively rare complication after living-donor liver transplantation, which sometimes leads to a life-threatening event owing to gastrointestinal bleeding or graft failure. This study sought to evaluate the diagnoses and management of late-onset portal vein stenosis in pediatric living-donor liver transplants. MATERIALS AND METHODS Since September 2001, we performed 123 living-donor liver transplant procedures in 120 children, among which 109 children with a functioning graft at 6 months after living-donor liver transplant are included in this analysis. Seven instances of portal vein stenosis were diagnosed and were analyzed retrospectively. RESULTS The median age of the children was 5.3 years, and the median body weight was 19.2 kg. Portal vein stenosis was diagnosed at 11.2±3.1 months after living-donor liver transplantation. Whereas 3 children were asymptomatic, splenomegaly and/or massive ascites were observed in the remaining 4. Additionally, platelet counts were below the normal limit in 4 children. All children were treated with transhepatic balloon dilatation except 1. Intraluminal stent placement was needed in 1 child owing to resistance of balloon dilatation. The mean pressure gradient decreased from 12.4 to 3.2 mmHg after successful treatment. We did not observe any treatment-related complications. Portal venous patency was maintained in all children during posttreatment follow-up of 43.2±20.4 months. There were no recurrences of portal vein stenosis. One child died; the remaining 6 children are alive with good graft function at 49.8±23.9 months of follow-up. CONCLUSION Although most portal vein stenosis is asymptomatic, splenomegaly and platelet counts are 2 important markers for portal vein stenosis. Early detection of portal vein stenosis with these 2 markers can lead to successful interventional percutaneous approaches and avoid graft loss.

Abstract
PURPOSE In pediatric liver transplantation, Roux-en-Y hepaticojejunostomy is often preferred for biliary reconstruction, especially in living-donor liver transplantation (LDLT). Limited numbers of duct-to-duct biliary reconstructions have been presented in pediatric recipients. We retrospectively reviewed our experiences with duct-to-duct biliary reconstruction without a stent in pediatric LDLT recipients. MATERIALS AND METHODS Since September 2006, 32 LDLTs were performed using a duct-to-duct biliary reconstruction without a stent in 31 children (16 boys and 15 girls; overall mean age, 8.3±5.1 years). We transplanted 19 left lobe grafts, 11 left lateral segments, 1 monosegment, and 1 reduced-size right lobe graft. Twenty-eight grafts had a single bile duct; the remaining 4, two bile ducts. We created a single orifice at the back table for the grafts that had 2 bile ducts. RESULTS Two recipients developed bile leakage in the early postoperative period; 3 bile duct stenoses occurred in the late postoperative period. All biliary complications were successfully treated with interventional radiologic or endoscopic approaches. There was no morbidity and no graft loss owing to biliary complications. During a mean follow-up of 23.5±13.6 months (range, 4-44), 4 children died and the remaining 27 (88%) are doing well with satisfactory liver function. CONCLUSION Our results showed that duct-to-duct biliary reconstruction without a stent was a safe technique for biliary reconstruction even among pediatric cases.

Abstract
Orthotopic and living related liver transplantation is an established mode of treatment of end-stage liver disease. One of the major causes of postoperative complications is vascular anastomotic stenosis. One such set of such complications relates to hepatic vein, inferior vena cava (IVC), or portal vein stenosis, with a reported incidence of 1-3%. The incidence of vascular complications is reported to be higher in living donor versus cadaveric liver transplants. We encountered a patient with hepatic venous outflow tract obstruction, where the hepatic vein had been previously stented, but the patient continued to have symptoms due to additional IVC obstruction. The patient required double-balloon dilatation of the IVC simultaneously from the internal jugular vein and IVC.

Abstract
The initial imaging immediately after orthotopic liver transplantation is generally performed with ultrasound. Although significant posttransplant complications do occur, many abnormal findings including minor vascular waveform abnormalities, anastomotic mismatches, and fluid collections can be seen in asymptomatic patients. It is important to differentiate these benign findings from more serious complications to avoid unnecessary intervention.

Abstract
PURPOSE OF REVIEW Although liver transplantation has become a standardized treatment and the only established definite therapy for end-stage liver disease it remains a unique clinical procedure. Increased understanding of the specific pathophysiological changes in end-stage liver disease and the transplantation procedure have led to the adaptation of concepts including overall monitoring of the patient and assessment of specific organ function. RECENT FINDINGS Major emphasis is placed on adequate monitoring during perioperative care of liver transplantation patients in order to ensure optimal hemodynamic and respiratory performance. The immediate assessment of metabolism and graft function will also serve to guide therapy according to the individual patient's needs. SUMMARY The evolution of monitoring during standardized liver transplantation, as well as currently recommended novel devices and concepts, are described and discussed.

Abstract
Arteriovenous fistula (AVF) involving the inferior mesenteric vessels is rare, and the affected patients usually present with abdominal pain, mass, or features of established portal hypertension. Colonic ischemia is a less common and more serious manifestation of AVF. We report a case of ischemic colitis secondary to inferior mesenteric AVF in a patient who underwent a previous liver transplantation, subsequently developed portal vein stenosis, and then presented with acute lower gastrointestinal bleeding. He underwent percutaneous transhepatic placement of a portal vein stent and left colectomy.

Abstract
BACKGROUND Haematopoietic stem cell transplantation (HSCT) can be used to cure or ameliorate a variety of non-malignant diseases. These range from inherent defects of haematopoiesis, through metabolic diseases, to severe autoimmune diseases. The rationale for this strategy is based on the concept of immunoablation using high-dose chemotherapy, with subsequent regeneration of naïve T-lymphocytes derived from reinfused haematopoietic progenitor cells. Possibly the use of SCT allows the administration of high-dose chemotherapy resulting in a prompt remission in these therapy-refractory patients. AIM This review highlights the major scientific developments and defines the areas of successful use of HSCT in gastrointestinal disorders and gives a perspective on possible future applications. METHODS A search in the Medline has been conducted and all relevant published data were analysed. RESULTS HSCT has been proved successful in treating refractory Crohn's disease. A selected group of refractory coeliac patients having a high risk of developing enteropathy associated T-cell lymphoma has been recently treated with promising results. In cryptogenic cirrhosis, basic research and unpublished data concerning mesenchymal SCT are encouraging. CONCLUSION In refractory autoimmune gastrointestinal diseases, it seems that high-dose chemotherapy followed by HSCT is feasible and safe and might result in long-term improvement of disease activity.

Abstract
In the absence of cadaveric donor liver transplantation, living-donor liver transplantation (LDLT) is an alternative option for patients with end-stage liver disease. The objective of this study was to evaluate the outcome of LDLT at a single medical center in Turkey. We retrospectively analyzed the results of 101 LDLTs in 99 recipients with end-stage liver disease. We transplanted 49 right liver lobes, 16 left lobes, and 36 hepatic segments II and III. Most donors (46%) were parents of the recipients. Seventeen recipients had concomitant hepatocellular carcinoma and cirrhosis. Retransplantation was performed in two recipients. Ten hepatic arterial thromboses, 1 hepatic arterial bleeding, and 12 biliary leaks occurred in the early postoperative period. Most complications were treated with interventional techniques. Three hepatic vein stenoses, three portal vein stenoses, one hepatic arterial stenosis, and six biliary stenoses developed during the late postoperative period. Recipients with those complications were treated with interventional techniques. Mean follow-up was 14.2 +/- 10.9 months. During that time, no tumor recurrence was detected in any recipient with hepatocellular carcinoma. Twenty-two recipients died during the follow-up. At this time, the remaining 77 recipients (77%) are alive, exhibiting good graft function. In general, complication rates are slightly higher after LDLT than after cadaveric liver transplantation. However, most complications can be treated with interventional techniques. LDLT continues to be a life-saving option in countries without satisfactory cadaveric donation rates.

Abstract
Portal venous stenosis is relatively a rare complication after liver transplantation in children and it sometimes leads to life threatening event due to gastrointestinal bleeding or graft failure. Recently, balloon dilatation has been widely accepted as a treatment of choice for the management of portal venous stenosis. The purpose of this study was to evaluate the feasibility of transileocolic venous balloon dilatation for the management of primary and recurrent portal venous stenosis after living donor liver transplantation (LDLT) in children. The records of 57 pediatric liver transplants were retrospectively reviewed. Nine patients (15.8%) with portal venous stenosis were identified. Seven symptomatic children with portal venous stenosis underwent balloon dilatation. Two approaches were employed for balloon dilatation; the transileocolic venous approach and the percutaneous transhepatic approach. In patients with recurrent stenosis, careful follow-up was carried out while they were asymptomatic. Twelve balloon dilatations were performed in seven children with primary or recurrent portal venous stenoses. The initial technical success rate was 91.7% (11/12), while 6 out of 12 (50.0%) procedures resulted in recurrent stenosis. Five out of six recurrent stenoses required repeated balloon dilatation. The clinical success rate of balloon dilatation in our study was 85.7% (6/7). Other than recurrent stenosis, two procedure-related complications occurred. In conclusion, transileocolic venous balloon dilatation was a safe and effective procedure for portal venous stenosis after LDLT in children.

Abstract
Living-donor liver transplantation is another treatment option to cadaveric liver transplantation in adult recipients. We report the outcomes of 49 right lobe adult living-donor liver transplantations performed at our institution between April 2003 and June 2006. The mean age of the recipients was 41.7 +/- 12.5 years. The median graft-to-recipient weight ratio was 1.2% +/- 0.4%. In recipients, the mean operative time was 10.6 +/- 2.7 hours. The mean number of blood transfusions administered was 4.1 +/- 5.1 units. The mean time spent in the intensive care unit was 2.3 +/- 1.5 days. In recipients, five vascular and five biliary complications occurred during the early postoperative period, and four vascular and two biliary complications developed in the late postoperative period. Thirteen of the 49 recipients died within 4 months of surgery. The mean age of the donors was 36.6 +/- 9 years. In the donors, the mean operative time was 6.4 +/- 1.6 hours, mean residual liver volume was 43.3% +/- 6.1%, and the mean hospital stay was 9.5 +/- 4.5 days. Two donors required an intraoperative blood transfusion. None of our donors died, but six complications occurred in four donors. The mean postoperative follow-up was 13.4 +/- 9.6 months. In conclusion, in Turkey, as in other countries, organ demand exceeds organ availability. Graft size presents a problem for adult recipients, but right lobe living donor transplant may be a life-saving option for these recipients when performed by experienced surgical teams.

Abstract
Orthotopic liver transplantation remains a major medical and surgical challenge in small pediatric patients. From April 2003 to June 2006, 21 small babies (each of whom weighed less than 10 kg or was younger than 1 year of age) underwent orthotopic liver transplantation. Five were girls and 16 were boys with a mean age of 15.7 +/- 9.3 months (range, 2-24 months); their mean weight at the time of transplantation was 9.8 +/- 3.6 kg (range, 6-16 kg). All transplants were obtained from a living-related donor. Left lateral segment was used for all transplantations. The median graft-to-recipient weight ratio was 3.5% +/- 1.2% (range, 1.5%-6.1%). During the early postoperative period, hepatic arterial thrombosis was identified in 4 patients, and a biliary leak was detected in 2 patients. In 2 patients, portal vein stenosis was identified during the late postoperative period. At the time of this writing, the 17 alive patients (81%) exhibited good graft function at median follow-up of 14.8 +/- 10.9 months (range, 1-39 months). Four patients died during the follow-up. Histological examination revealed hepatocellular carcinoma in 2 patients, and Burkitt's lymphoma in 1 patient. In conclusion, our data confirmed that living-related donors, especially in this age group, provide a reliable source for the organ pool. Satisfactory results can be achieved despite the anatomic handicaps of this age group.

Abstract
Orthotopic liver transplantation (OLT) remains a major medical and surgical challenge in small pediatric patients. From April 2003 through October 2005, 17 infants (each of whom weighed less than 10 kg) underwent the procedure. Four were girls and 13 were boys (mean age, 15.7 +/- 9.3 months [range, 2-36 months]; mean weight at the time of transplantation, 7.4 +/- 2.6 kg [range, 6-10 kg]). All transplants were obtained from living-related donors. Sixteen left lateral segments and 1 left lobe were transplanted. The median graft-to-recipient weight ratio was 3.5% +/- 1.2% (range, 1.5%-6.1%). During the early postoperative period, hepatic arterial thrombosis was identified in 2 infants, and a biliary leak in 1. Hepatic arterial thrombosis was treated by reanastomosis with polytetrafluoroethylene grafting in the first patient and by surgical embolectomy in the second. The biliary leak was treated with percutaneous drainage. In 1 infant, portal vein stenosis, which was identified during the late postoperative period, was treated by percutaneous balloon dilatation. At this time, 14 (82.3%) infants were alive, exhibiting good graft function at a median follow-up of 11 months (range, 2-36 months). Three infants died: 1 on postoperative day 47 from adult respiratory distress syndrome, 1 on postoperative day 12 from sepsis, and 1 on postoperative day 65 from sepsis associated with EBV infection. Episodes of acute rejection, which occurred in 5 patients, were treated with pulse steroid therapy. On follow-up, histologic examination revealed hepatocellular carcinoma in 2 infants and Burkitt's lymphoma in 1 infant. Our data confirm that extensive use of living-related donors in liver transplantation can result in an excellent outcome for small pediatric patients.
