RESUMO
This study aimed to demonstrate the efficacy of our diagnostic and therapeutic management algorithm and catheter-assisted (percutaneous transhepatic biliary tract drainage [PTBD] or transanastomotic feeding tube) hepaticojejunostomy (HJ) procedures in living liver donors (LLDs) with biliary complications. Living donor hepatectomy (LDH) was performed between September 2005 and April 2021 in 2 489 LLDs. Biliary complications developed in 220 LLDs (8.8%), 136 of which were male, and the median age was 29 (interquartile range [IQR]: 12) years. Endoscopic sphincterotomy ± stenting was performed in 132 LLDs, which was unsuccessful in 9 LLDs and required HJ. Overall, 142 LLDs underwent interventional radiologic procedures. Fifteen LLDs with biliary complications underwent HJ (PTBD catheter = 6 and transanastomotic feeding tube = 9) at a median of 44 days (IQR: 82). Following HJ, 14 LLDs did not have any complications throughout the median follow-up period of 1619 days (IQR: 1454). However, percutaneous dilation for HJ anastomotic stricture was performed in one patient. Biliary complications are very common following LDH; therefore, surgeons in the field should have a low threshold to perform HJ for biliary complications that persist after other treatments. Our catheter-assisted HJ techniques demonstrated a high success rate and aided HJ in a hostile abdomen during revisional surgery.

BACKGROUND/AIM: With the COVID-19 pandemic, managing the process of solid organ transplantation has become a significant matter for transplant centres. In this study, we report our experiences on evaluating the effects of COVID-19 in patients with recent liver transplants. MATERIALS AND METHODS: We evaluated patients who received liver transplants during three close consecutive periods of time. For transplants conducted between October 1 and December 31, 2019, January 1 and March 10, 2020 and March 11 and June 22, 2020, the lung tomographies of patients were inspected for radiological signs of viral pneumonia. For patients after March 11, 2020, the hospital's electronic database system was scanned for preoperative and postoperative SARS-CoV-2 testing from Real-time Polymerase Chain Reaction (RT-PCR) of the respiratory tract samples. RESULTS: A total of 149 patients over the age of 18 who received liver transplants at our centre between October 1, 2019 and June 22, 2020 were evaluated. During this time span, our centre conducted liver transplants on patients from 34 different provinces and also abroad. Within this time period, a total of nine patients had respiratory samples with a positive SARS-CoV-2 RT-PCR test. PCR of respiratory tract samples was performed in 21 (14%) patients to identify the other potential infective agents in the respiratory tracts; Rhinovirus and Influenza A were detected in two and respiratory syncytial virus (RSV) was detected in one patient. During the transplant periods, 99 (67.1%) patients were evaluated with computed tomography (CT). The CT findings of 18 (12%) patients were consistent with viral pneumonia. There was a statistically significant difference between the groups only in terms of air bronchogram findings (P = .012). CONCLUSION: The clinical status of our short-term liver transplant patients was far better than we originally anticipated, but it remains obvious that the necessary precautions should continue to be taken.

Diaphragmatic hernias (DHs) are rare complications after pediatric liver transplantation (PLT). It is now widely accepted that DHs after liver transplantation (LT) is a pediatric related condition. PLTs (under of age 18) performed between January 2013 and June 2019 at Malatya Inonu University Institute of Liver Transplantation were retrospectively scanned. Study group consisting DHs and a control group were compared. Among 280 PLTs, 8 of them were complicated with DHs (%2.9). Median age of the patients with DH was 3.0 (0.8-9.5) years. Median graft recipient weight ratio was 2.5 (0.9-4.4). Five patients were below 5th percentiles in terms of pediatric weight growth chart at the time of LT. Also, 6 patients were below 5th percentiles in terms of pediatric height growth chart. There was no statistical difference between study and control groups. There are many risk factors mentioned in literature that may be primarily responsible for DHs after PLT. These factors are left lobe and large-for-size grafts, malnutrition, trauma or diathermy of diaphragmatic nerve and vessels and immunosuppressants. In our study, we could not specify any reason that differs in DHs. In our aspect, narrow diaphragma and thorax are exposed to high intra-abdominal pressure from abdomen. Large-for-size grafts, which are specific to children, also may contribute to this affect. Excessive diathermy and trauma to diaphragmatic collaterals may aggravate the risk of DH. More patients are needed to make an exact conclusion, in order to evaluate with comparable study on this aspect.

Reconstruction of anomalous portal vein branching (APVB) during right lobe living donor liver transplantation (LDLT) can be challenging. The goal of this article is to describe our surgical technique, named the Malatya Approach, in case of APVB during right lobe LDLT. The technique unifies the APVB and obtains a funnel-shaped common extension with a circumferential fence by a saphenous vein conduit. In total, 126 (10.6%) of 1192 right lobe grafts had APVB that were divided into 2 groups according to the adopted surgical techniques: the Malatya Approach group (n = 91) and the previously defined other techniques group (n = 35). Both groups were compared regarding portal vein thrombosis (PVT), postoperative 90-day mortality and survival. PVT developed in 3 patients (3.3%) in the Malatya Approach group and developed in 10 (28.6%) patients for the other group (P < 0.001). There were 8 (8.8%) 90-day mortalities in the Malatya Approach group (1 PVT related) and 15 patients (9 PVT related) died in the other techniques group (P < 0.001). Mean follow-up time for both groups was similar (999.1 days for the Malatya Approach group versus 1024.7 days for the other group; P = 0.47), but longterm survival in the Malatya Approach group was better than in the other group (84.6% versus 40%; P < 0.001). Multivariate analysis revealed that the Malatya Approach group showed less PVT development and longer survival (P < 0.001). This technique is promising to avoid PVT and mortalities in cases of APVB during right lobe LDLT. Liver Transplantation 23 751-761 2017 AASLD.

We herein describe two cases of liver transplantation with portal vein thrombosis. In both cases, a tear advancing to the retropancreatic area occurred during portal vein thrombectomy. Hemorrhage from the limited visibility retropancreatic area made it impossible to stop the bleeding by clamping or direct suturing, and the clamping and suturing efforts actually increased the hemorrhage, possibly due to the damaged and thin portal vein wall. First, finger compression over the retropancreatic area was employed to stop the bleeding, then a Foley urinary catheter was introduced into the portal vein under the finger. The balloon of the catheter was inflated with 8 cc of normal saline, and the finger was released. The bleeding was stopped temporarily, and two different venous conduits were sutured to the trimmed portal vein stump in a bloodless surgical area. The venous conduits were easily controlled with vascular clamps after deflating the balloon catheters, and implantation of the liver was then done in a standard manner. Balloon tamponade can be a lifesaving technique that can temporarily stop a hemorrhage to allow for definitive repair in cases of retropancreatic portal vein hemorrhage.

Background and Aim: Patients with hepatocellular carcinoma (HCC) are managed in various hospital departments, which complicates the assessment of the overall picture. In our large liver transplant institute, we evaluate all HCC patients in a weekly multi-disciplinary liver tumor board, and their data are prospectively collected in an institutional HCC database to evaluate HCC causes, tumor features, treatments, and survival. Materials and Methods: Baseline data for patients (n=1322) were prospectively recorded, including hepatitis status, routine clinical serum parameters, radiological assessment of maximum tumor diameter (MTD), tumor number, presence of macroscopic portal vein thrombosis (PVT), and serum alpha-fetoprotein (AFP) levels. Results: Cirrhosis was found in 81.1% of patients; 58.5% had hepatitis B virus (HBV), 14.9% hepatitis C virus (HCV), 8.9% cryptogenic cirrhosis, and less than 2% had alcoholism. MTD was <5 cm in 61.95% of patients, and 31.9% had PVT. The median overall survival was more than six-fold greater for the 444 liver transplant patients than for those without surgery. Transplanted patients had smaller tumors, whereas larger tumors (MTD >10 cm) were primarily in the no-surgery group. Parallel differences were found for AFP levels (highest in the no-surgery group). PVT was present in similar proportions (25.0% for transplant, 28.0% for no-surgery). The presence of cirrhosis was higher in the transplant group. MTD and levels of serum AFP, gamma-glutamyl transferase (GGT), and blood platelets were prognostic parameters for transplant. Furthermore, AFP and GGT levels were prognostic for transplanted PVT patients. Only albumin was prognostic in the no-surgery patients. Conclusion: Transplanted HCC patients have longer survival, smaller tumors, and more severe liver damage than no-surgery patients. Prognostic subsets were identified within the surgery and the PVT groups.
RESUMO
Background: Treatment of established portal vein narrowing after living donor hepatectomy is challenging. We aimed to present a new approach termed the "elbow patch reconstruction technique" to correct the narrowed remnant portal vein just or late after right lobe living donor hepatectomy. Methods: Demographic and clinical data of 12 living liver donors with narrowed remnant portal veins and treated with the "elbow patch reconstruction technique" were prospectively collected and retrospectively evaluated. Anatomic variation of the portal vein was defined in accordance with the Nakamura classification; six of the living liver donors had type A, three had type B, and the remaining three had type C. In eight of the living liver donors with a narrowed remnant portal vein, diagnosis was detected by intraoperative Doppler ultrasonography and visual inspection by experienced transplant surgeons in the living donor hepatectomy procedure. In the remaining four living liver donors, diagnosis was performed postoperatively when elevation of liver enzymes was noticed during the routine liver function test and Doppler US. The diagnosis was confirmed by multidetector computed tomography. Results: Data from nine males and three females aged 18 to 54 years were analyzed. All of the living liver donors were followed up for a median of 1710 days (min-max: 1178-4447 days; IQR: 1516 days), and none of the living liver donors had any structural or functional complications in the portal vein. Conclusions: Narrowing remnant portal veins are rare, but they are a life-threatening complication in living liver donors, and this condition requires urgent management. Image guided interventions and narrowed segment resection with end-to-end anastomosis using a vascular graft carried a potential risk for thrombosis and restenosis. To avoid these complications, we shared a technique named "elbow patch reconstruction technique". This technique can be very effective in relieving the narrowing of the remnant portal vein after right lobe living donor hepatectomy.
RESUMO
AIM AND BACKGROUND: Preparation of the patients for liver transplantation is a meticulous process and includes evaluation of tumor markers to rule out occult malignancy. The present study evaluated the significance of serum tumor markers in patients bound for liver transplantation due to viral and other etiologies of liver failure. PATIENTS AND METHODS: Three hundred eighty-one patients who underwent liver transplantation were included in the study. Demographic data, model for end stage liver disease (MELD) scores, and serum tumor marker levels were prospectively collected. RESULTS: AFP levels were significantly higher in viral etiologies when compared to other etiologies (p < 0.05). Ca 19-9 was significantly higher in viral etiologies (p < 0.05). Among the viral etiologies, HCV-related liver failure had higher carcinoembryonic antigen (CEA) and carbohydrate antigen 19-9 (Ca 19-9) levels (p < 0.05). A correlation was found between increasing MELD scores and serum levels of tumor markers (p < 0.05). CONCLUSIONS: Tumor markers such as AFP, CEA, Ca 125, and Ca 19-9 can be elevated in end stage liver disease. Their levels vary according to etiology and severity of disease. The diagnostic capabilities of these markers are reduced in end stage liver disease setting but they contribute to the evaluation of the pathophysiology of chronic liver disease. Transplantation can be performed safely in cases with high tumor marker levels provided that any occult malignancy is ruled out by means of imaging and endoscopic techniques. Tumor markers can guide the physician in determining the severity of liver cirrhosis, and further studies are needed to validate such a relationship.

BACKGROUND: COVID-19 has led to an unprecedented global health crisis. This situation caused an immediate reduction in solid organ transplantation activity. This study aimed to present the follow-up results of patients with chronic liver disease who underwent liver transplantation (LT) after a history of COVID-19 infection. METHODS: Sociodemographic characteristics and clinicopathological data of 474 patients who underwent LT at Inonu University Liver Transplant Institute between March 11, 2020 and March 17, 2022 were prospectively recorded and analyzed retrospectively. Among these, the data of 35 patients with chronic liver disease who were found to be exposed to COVID-19 infection in the pre-LT period were analyzed for this study. RESULTS: The median body mass index, Child score, and Model for end-stage liver disease/ Pediatric end-stage liver disease scores of the 35 patients were calculated as 25.1 kg/m2 (IQR: 7.4), 9 points (IQR: 4), and 16 points (IQR: 10), respectively. Graft rejection occurred in 4 patients at a median of 25 days post-transplant. Five patients underwent retransplantation at a median of 25 days post-transplant. The most common cause of retransplantation is early hepatic artery thrombosis. There were 5 deaths during postoperative follow-up. Mortality developed in 5 (14.3%) patients exposed to COVID-19 infection in the pretransplant period, whereas mortality occurred in 56 (12.8%) patients not exposed to COVID-19 infection. There was no statistically significant difference in mortality between the groups (P = .79). CONCLUSIONS: The results of this study showed that exposure to COVID-19 before LT does not affect post-transplant patients and graft survival.

AIM: This study aimed to evaluate the course of bone and mineral metabolism after liver transplantation (LT) in patients with chronic liver disease. METHODS: One hundred four patients who had undergone LT and had a minimum of 6 months of follow-up after LT were included in this prospective cohort study. The following parameters were evaluated for each patient: preoperative and postoperative (postoperative day [POD]30, POD90, POD180) osteocalcin, bone-specific alkaline phosphatase (BALP), type 1 collagen, beta-C-terminal end telopeptide (ß-CTx), vitamin D, parathyroid hormone (PTH), ALP, calcium, phosphate, sedimentation, and bone mineral densitometer scores (L2, L4, L total, and F total). The parameters were compared in terms of sex, presence of liver tumor (hepatocellular carcinoma [HCC; n = 19] vs non-HCC [n = 85]), and presence of autoimmune liver disease (autoimmune liver disease [ALD; n = 8] vs non-ALD [n = 96]). RESULTS: The median age of the patients (n = 81 men and n = 23 women) was 52 years (95% CI, 50-56). There was a significant change in the defined time intervals in parameters such as osteocalcin (P < .001), BALP (P < .001), ß-CTx (P < .001), vitamin D (P < .001), PTH (P < .001), ALP (P = .001), calcium (P < .001), phosphate (P = .001), L2 (P = .038), L total (P = .026), and F total (P < .001) scores. There was a significant difference in POD90 ALP (P = .033), POD180 calcium (P = .011), POD180 phosphate (P = .011), preoperative sedimentation (P = .032), and POD180 F total (P = .013) scores between both sexes. There was a significant difference in POD180 osteocalcin (P = .023), POD180 ß-CTx (P = .017), and preOP calcium (P = .003) among the HCC and non-HCC groups. Furthermore, we found significant differences in preoperative ALP (P = .008), preoperative sedimentation (P = .019), POD90 (P = .037) and POD180 L2 (P = .005) scores, preoperative (P = .049) and POD180 L4 (P = .017), and POD180 L total (P = .010) and F total (P = .022) scores between the patients with and without ALD. CONCLUSION: This study shows that the bone and mineral metabolism of the LT recipients was negatively affected after LT. In addition, we showed that bone and mineral metabolism was more prominent in patients with HCC, and bone mineral density scores were higher in patients with ALD.

OBJECTIVES: The purposes of this study were to determine the incidence of acute pancreatitis after living donor hepatectomy and to investigate potential risk factors and outcomes. MATERIALS AND METHODS: Clinical data of all donors who underwent donor hepatectomy between January 2015 and December 2016 in our liver transplant institute were reviewed. Donor data were obtained from a prospectively maintained database. The donors were divided into 2 groups according to whether they developed postoperative pancreatitis. The following data were compared between the 2 groups: demo-graphic information (age, sex), body mass index, type of hepatectomy (right, left, or left lateral), intraoperative cholangiographic findings, operative time, blood loss, graft data (graft weight, remnant liver ratio), duration of postoperative hospital stay, and postoperative morbidity and mortality (if any). Pancreatitis severity and treatment outcomes were also examined in patients with postoperative pancreatitis. RESULTS: Our study included 348 donors who underwent donor hepatectomy for living-donor liver transplant. Postoperative pancreatitis developed in 6 donors (1.7%). We found no statistical differences between patients with and without postoperative pancreatitis in terms of demographic and intra-operative findings. Neither loco-regional nor systemic complications of pancreatitis developed in any of the patients. Therefore, all were classified as having mild pancreatitis according to revised Atlanta classification. The mean APACHE II score was 5.2 ± 1.2 points (range, 4-7 points). All patients with postoperative pancreatitis received conservative-supportive treatment. CONCLUSIONS: Although postoperative pancreatitis is a rarely reported complication in living liver donors, it should always be considered, especially in patients who unpredictably deteriorate in the postoperative period. Proper recognition and timely treatment can help avoid s erious consequences.

BACKGROUND: To present the struggle of a high volume liver transplant center against coronavirus infectious disease-2019 pandemic. METHODS: Between March 2020 and December 2020, the demographic and clinical data of staff and liver transplant candidates diagnosed with coronavirus infectious disease-2019 in our Liver Transplant Institute were prospectively analyzed. RESULTS: First, 32 healthcare staff were diagnosed with coronavirus infectious disease-2019, and 6 of them were surgeons. Six staff were asymptomatic, while 24 staff had mild or moderate and 2 staff had severe coronavirus infectious disease-2019. All the staff recovered from the disease without any permanent sequela and returned to duty after 2 consecutive negative polymerase chain reaction results within 24-hour intervals. Second, during the preoperative investigation, 6 living liver donor candidates and 13 recipients were tested positive for coronavirus infectious disease-2019 (son = 6, unrelated = 3, cousin = 3, daughter = 2, cadaveric = 1). Eleven patients received favipiravir and 8 did not receive any treatment because they were asymptomatic. Only one recipient who had severe coronavirus infectious disease-2019 died due to multiple organ failure syndrome. One recipient died in the early postoperative period. The median duration from the initial diagnosis of the patients till the transplant procedure was 21 days (min-max: 14-105 days). During the time of operation, the polymerase chain reaction tests of the donors and the recipients were negative, and the thorax tomography images showed no signs of viral pneumonia. CONCLUSION: Meticulous precautions, multidisciplinary approach, team effort, and organization of facilities can increase the quality of care of these patients in the coronavirus infectious disease-2019 era. Healthcare workers have shown tremendous effort and are the true heroes of this era.

BACKGROUND: In recent years, the number of liver transplantations for advanced-stage liver diseases has considerably increased and the patients have a wide range of dermatologic manifestations. AIM: This study aims to reveal cutaneous, mucosal, and nail lesions in liver transplant recipients in quite large patient series. PATIENTS/METHODS: The study included 520 patients in the Inonu University Liver Transplantation Institute. New and followed-up patients attended to the study between May and October 2019. The patients were examined by a dermatologist, and their data were recorded. RESULTS: The study included 163 female and 357 male patients with the main age of 44.20 ± 18.18 (range: 1-83 years), and 465 livers (89.4%) were taken from live donors, while 54 livers (10.4%) were taken from cadavers. A total of 314 (60.4%) patients had dermatophyte infections, 174 (33.4%) patients had pathological nail changes, and 427 (82.1%) patients had oral mucosal lesions. Graft-versus-host disease (GVHD) developed in 9 (1.73%) patients after the transplantation, and 5 patients died of GVHD. Four patients had cutaneous malignancies. CONCLUSIONS: Tumoral and nontumoral dermatological diseases may be encountered following the transplantation depending on underlying liver disease, immunosuppressive treatment, the graft itself, or any primary cutaneous disease. Liver transplantation recipients require a multidisciplinary clinical approach, and dermatological care must be an integral part of this approach.

Coronavirus 2019 (COVID-19) is a new infectious disease that continues to spread globally. There is growing concern about donor-induced transmission of Coronavirus 2 (SARS -CoV-2). For liver transplantation, the COVID-19 PCR test is routine, in addition to epidemiological history and clinical and radiological examination 24-48 h before surgery. One of the liver transplant candidates was found to be infected with COVID-19, as well as the planned donor candidate. Since COVID-19 will be a high-risk operation for both the recipient and the donor, the operation was postponed by giving medical treatment. After the treatment and quarantine process was over, the patient and the donor then had a negative COVID-19 PCR test and the patient received a living donor liver transplant. We present a case of donor and recipient who initially both tested positive for COVID-19. This liver transplantation scenario has not previously been reported in the literature.

INTRODUCTION: The most common biomarker for HCC is serum alpha-fetoprotein (AFP). AFP is used for screening and diagnosing HCC, and also, it is used for predicting prognosis and monitoring the response to treatment. DISCUSSION: AFP secretion is associated with poor tumor histologic grade and aggressive tumor biological behavior. The risk of dropout on the waiting list for liver transplantation and the risk of tumor recurrence after liver transplantation are associated with high AFP serum levels. Therefore, using AFP levels for selecting patients to include on the liver transplantation waiting lists is critical. It is also known that a low AFP serum level before liver transplantation has limited informative value, but high AFP levels prior to liver transplantation indicate a higher risk for HCC recurrence. CONCLUSION: AFP's performance as a screening, diagnostic, and prognostic marker for HCC is not ideal, but it is the most frequently used biomarker in the management of HCC.

PURPOSE: To evaluate the effect of hepatitis D virus (HDV) on hepatitis B virus-hepatocellular carcinoma (HBV-HCC) co-recurrence in patients undergoing living donor liver transplantation (LDLT) for HBV alone or HBV-HDV coinfection. METHODS: Between 2002 and 2019, 254 HBV-HCC patients underwent LDLT. The patients were divided into two groups after the application of the exclusion criteria: HBV-HCC (Group B; n = 163) and HBV-HDV-HCC (Group D; n = 31). First, the B and D groups were compared in terms of demographic and clinical parameters. Second, patients with (n = 16) and without (n = 178) post-transplant HBV-HCC co-recurrences were grouped and compared in terms of the same parameters. RESULTS: Although the risk of HBV-HCC co-recurrence in group D was 4.99-fold higher than in group B, the risk of HBV recurrence alone in group D was 12.5-fold lower than in group B. The AFP (OR = 4.4), Milan criteria (beyond; OR = 18.8), and HDV (OR = 8.1) were identified as the independent risk factors affecting post-transplant HBV-HCC co-recurrence. The Milan criteria (OR = 2.1) and HBV-HCC co-recurrence (OR = 10.9) were identified as the risk factors affecting post-transplant mortality. HBV-HCC co-recurrence developed in 26.5% of patients in Group B and 100% in Group D (OR = 40; p = 0.001). HCC recurrence alone developed in 10% of patients without HBV recurrence in group B and 0% of patients without HBV recurrence in group D (OR = 5.7). CONCLUSION: This study showed that the risk of HBV recurrence alone was reduced by 12.5-fold in the presence of HDV; however, the HCC recurrence occurred in all patients with HDV when HBV recurrence developed.

BACKGROUND: Serum AFP levels are typically elevated in less than 50% of hepatocellular cancer (HCC) patients. Gamma-glutamyl transpeptidase (GGT) levels have been suggested to be a potentially useful HCC biomarker. AIMS: To assess in a cohort of prospectively evaluated HCC patients who underwent liver transplant and whose survival was known; the occurrence, prognosis, and clinical characteristics of patients with elevated serum GGT levels. RESULTS: Serum GGT levels were found to be elevated in a higher proportion in patients with either small or large HCC than alpha-fetoprotein (AFP) levels, and were significantly related to prognosis in patients with large size HCCs. There was no clear correlation between GGT and AFP levels, likely reflecting different HCC characteristics or HCC cell lineages associated with these two markers. Furthermore, elevated GGT was found in 24% of low-AFP patients with small tumors and 46% with large tumors. Elevated GGT levels were also significantly associated with microvascular invasion and tumor diameter. CONCLUSIONS: Elevated serum GGT levels were associated with HCC size and worse survival, and were unrelated to AFP levels. GGT may be a useful prognostic tumor marker, especially for low-AFP HCC patients.
