In living-donor liver transplantation, biliary complications including bile leaks and biliary anastomotic strictures remain significant challenges, with incidences varying across different centers. This multicentric retrospective study (2016-2020) included 3633 adult patients from 18 centers and aimed to identify risk factors for these biliary complications and their impact on patient survival. Incidences of bile leaks and biliary strictures were 11.4% and 20.6%, respectively. Key risk factors for bile leaks included multiple bile duct anastomoses (Odds Ratio [OR] 1.8), Roux-en-hepaticojejunostomy (OR 1.4), and a history of major abdominal surgery (OR 1.4). For biliary anastomotic strictures, risk factors were ABO-incompatibility (OR 1.4), blood loss >1 liter (OR 1.4), and previous abdominal surgery (OR 1.7). Patients experiencing biliary complications had extended hospital stays, increased incidence of major complications, and higher Comprehensive Complication Index (CCI®) scores. The impact on graft survival became evident after accounting for immortal time bias using time-dependent covariate survival analysis. Bile leaks and biliary anastomotic strictures were associated with adjusted hazard ratios of 1.7 and 1.8 for graft survival, respectively. The study underscores the importance of minimizing these risks through careful donor selection and preoperative planning, as biliary complications significantly affect graft survival despite available effective treatments.

Perihilar cholangiocarcinoma (PHCC) has been a great challenge for surgeons, requiring advanced skills and expertise and was often associated with high morbidity and mortality. Resectability rates are up to 75% even in experienced centers. In patients with PHCC, radical liver and bile duct resection aiming R0 surgical margins offers the best long-term survival. Therefore, extensive resections with low FLR are commonly needed and PVE is offered to induce remnant liver hypertrophy for a long period. Associating liver partition with portal vein ligation for staged hepatectomy (ALPPS) is considered a promising approach inducing rapid remnant hypertrophy to prevent dropouts due to complications or tumor progression and increase resectability. Although poor results were reported initially, refinements in technique and risk adjustment of patient selection improved outcomes. The procedure is still under debate for the indication of PHCC. This article reviews the current literature on ALPPS in treatment of perihilar and intrahepatic cholangiocarcinoma.

Background: The aims of this study were to investigate biliary complications in liver transplant recipients with choledochocholedocho stomy anastomosis, to identify the risk factors for the development of such complications, and to evaluate the success of endoscopic approaches in liver transplant recipients. Methods: Between January 2013 and May 2021, a total of 238 patients with liver diseases underwent liver transplantation: 174 recipients undergoing choledochocholedochostomy anastomosis were included in the analysis. Results: Their median age was 54.0 years. The median posttransplant follow-up period was 29 months. Hepatitis B virus infection (33%) was the most common indication for liver transplantation. Most patients (87%) received living donor liver transplantation. The overall prevalence of posttransplant biliary complications was 31%. Anastomotic biliary strictures were the most common biliary complications (72%), followed by biliary leakage (13%). The median time between endoscopic retrograde cholangiography and liver transplantation was 4 months, with a mean of 3 ± 1.6 sessions. Endoscopic retrograde cholangiography-guided drainage and balloon dilation with or without stent placement was the most common treatment modalities for recipients with biliary strictures. The overall success rate of endoscopic treatment modalities was 83.3%, with 65% of the recipients exhibiting complete biochemical and endoscopic responses. The response did not differ significantly between living donor liver transplantation and cadaveric donor liver transplant recipients (P > .05). Three recipients required revision surgery for biliary complication repair. Six patients died due to biliary sepsis. Conclusion: Biliary stricture and leakages were the most common biliary complications after liver transplantation. Endoscopic treatment was successful in most recipients.

Background/Aims: Psychosocial and psychiatric evaluations are crucial components of the assessment of a live donor candidate. The Live Donor Assessment Tool (LDAT) was developed for this purpose. This study aims to evaluate the validity and reliability of the Turkish version of LDAT. Materials and Methods: 132 live kidney or liver donor were referred to assess their psychosocial/psychiatric appropriateness for donation and were randomized for clinical evaluation as usual or with LDAT. The internal consistency of LDAT was measured by Chronbach’s alpha coefficient. Inter-rater reliability was measured by using Spearman’s correlation coefficient. The potential validity of LDAT was assessed by comparing LDAT scores to clinical decisions. The Mann-Whitney U test was used to compare LDAT scores across two clinically classified groups (acceptable/declined). Logistic regression was performed using LDAT scores to predict the clinical decision. Results: The Turkish version of LDAT items demonstrate good internal consistency (α=0.773). Inter-rater reliability of LDAT demonstrated strong correlation (ICC=0.72). LDAT scores differentiated the accepted/declined groups, and strongly predicted the clinical decision. With a cut-off score of 60.5, LDAT was found to have high sensitivity and specificity. Conclusion: The Turkish version of LDAT was found to be a valid and reliable tool. LDAT could be an appropriate tool to assess live donor candidates.

Background and Objectives: The survival benefit of anatomical liver resection for hepatocellular carcinoma has not been elucidated yet. In this study, we aimed to investigate the effects of anatomic and non-anatomic liver resection on surgical outcomes in patients with hepatocellular carcinoma. Materials and Methods: A retrospective analysis of patients undergoing anatomic or non-anatomic resections due to hepatocellular carcinoma between March 2006 and October 2019 was conducted. Demographics, preoperative laboratory assessments, treatment strategies, and postoperative outcomes were analyzed. Results: The total cohort consisted of 94 patients, with a mean age of 63.1 ± 8.9 years, and 74.5% were male. A total of 41 patients underwent anatomic liver resection, and 53 patients underwent non-anatomic resection. The overall survival rates were found to be similar (5-year overall survival was 49.3% for anatomic resection and 44.5% for non-anatomic resection). Estimated median overall survival times were 58.5 months and 57.3 months, respectively (p = 0.777). Recurrence-free 1-, 3-, and 5-year survival rates were found to be 73.6%, 39.1%, and 32.8% in the non-anatomic resection group and 48.8%, 22.7%, and 22.7% in the anatomic resection group, respectively. Grade three or higher complication rates were found to be similar among the groups. Conclusions: This study did not find a difference between two surgical methods, in terms of survival. A tailored selection of the resection method should be made, with the aim of complete removal of tumoral lesions and leaving a suitable functional liver reserve, according to the parenchymal quality and volume of the liver remnant.
