Background and Aims: Patients with a choledochal malformation, formerly described as cysts, are at increased risk of developing a cholangiocarcinoma and resection is recommended. Given the low incidence of choledochal malformation (CM) in Western countries, the incidence in these countries is unclear. Our aim was to assess the incidence of malignancy in CM patients and to assess postoperative outcome. Methods: In a nationwide, retrospective study, all adult patients who underwent surgery for CM between 1990 and 2016 were included. Patients were identified through the Dutch Pathology Registry and local patient records and were analysed to determine the incidence of malignancy, as well as postoperative mortality and morbidity. Results: A total of 123 patients with a CM were included in the study (Todani Type I, n = 71; Type II, n = 10; Type III, n = 3; Type IV, n = 27; unknown, n = 12). Median age was 40 years (range 18‐70) and 81% were female. The majority of patients (99/123) underwent extrahepatic bile duct resection, with additional liver parenchyma resections in eight patients, only exploration in two, and a local cyst resection in eight patients. Postoperative 30‐day mortality was 2% (2/123) and limited to patients who underwent liver resection. Severe morbidity occurred in 24%. In 14 of the 123 patients (11%), a malignancy was found in the resected specimen. One patient developed a periampullary malignancy 7 years later. Conclusions: In a large Western series of CM patients, 11% were found to have a malignancy. This justifies resection in these patients, despite the risk of morbidity (24%) and mortality (2%).

Little is known about the achievement of developmental milestones (i.e., COL) after pediatric liver transplantation. The aim of this study was to examine the COL of young adults who underwent a liver transplantation during childhood and to compare it to healthy peers. Furthermore, we studied factors possibly related to their COL. COL was assessed using the CLQ, which assesses the achievement of developmental milestones (autonomy, psychosexual, social, and antisocial development) and risk behavior (substance abuse and gambling). Sociodemographic characteristics and clinical data were collected using the prospective institutional liver transplantation database. A total of 39 young adults who underwent a liver transplantation at the UMCG in their childhood completed the CLQ. They achieved fewer milestones with regard to autonomy, psychosexual, and social development compared to healthy peers, and they reported less risk behavior. Neither age at the time of study nor age at the time of transplantation was significantly correlated with any of the COL subscales. Young adults show delay in reaching developmental milestones in every dimension after a liver transplantation during their childhood. [ABSTRACT FROM AUTHOR]

Mortality of biliary atresia in children not undergoing liver transplantation in the Netherlands. Pediatr Transplantation 2011: 15:176-183. © 2010 John Wiley & Sons A/S. In order to further improve the outcome of BA, we characterized the mortality of BA patients who did not undergo OLT in the Netherlands, and compared our results with international data. For this purpose, we analyzed the causes of mortality of non-transplanted BA patients before the age of five yr, using the NeSBAR database. To evaluate trends in mortality, we compared the cohort 1987-1996 (n = 99) with 1997-2008 (n = 111). We compared clinical condition at OLT assessment with available international data, using the PELD-score. Mortality of non-transplanted BA children was 26% (26/99) in 1987-1996 and 16% (18/111) in 1997-2008 (p = 0.09). Sepsis was the prevailing direct cause of death (30%; 13/44). PELD-scores at the time of assessment were higher in non-transplanted BA patients (median 20.5; range 13-40) compared with international data (mean/median between 11.7 and 13.3). Based on our national data, we conclude that pretransplant mortality of BA patients is still considerable, and that sepsis is a predominant contributor. Our results strongly indicate that the prognosis of patients with BA in the Netherlands can be improved by earlier listing of patients for OLT and by improving pretransplant care.
