Surgical treatment of childhood hepatoblastoma in the Netherlands (1990–2013)

Background: Achievement of complete surgical resection plays a key role in the successful treatment of children with hepatoblastoma. The aim of this study is to assess the surgical outcomes after partial liver resections for hepatoblastoma, focusing on postoperative complications, resection margins, 30-day mortality, and long-term survival. Method: Chart reviews were carried out on all patients treated for hepatoblastoma in the Netherlands between 1990 and 2013. Results: A total of 103 patients were included, of whom 94 underwent surgery. Partial hepatectomy was performed in 76 patients and 18 patients received a liver transplant as a primary procedure. In 42 of 73 (58 %) patients, one or more complications were reported. In 3 patients, information regarding complications was not available. Hemorrhage necessitating blood transfusion occurred in 33 (45 %) patients and 9 (12 %) patients developed biliary complications, of whom 8 needed one or more additional surgical interventions. Overall, 5-year disease-specific survival was 82, 92 % in the group of patients who underwent partial hepatectomy, and 77 % in the group of patients who underwent liver transplantation. Conclusions: Partial hepatectomy after chemotherapy in children with hepatoblastoma offers good chances of survival. This type of major surgery is associated with a high rate of surgical complications (58 %), which is not detrimental to survival

Impaired Visual Integration in Children with Traumatic Brain Injury: An Observational Study

Background Axonal injury after traumatic brain injury (TBI) may cause impaired sensory integration. We aim to determine the effects of childhood TBI on visual integration in relation to general neurocognitive functioning. Methods We compared children aged 6-13 diagnosed with TBI (n = 103; M = 1.7 years post-injury) to children with traumatic control (TC) injury (n = 44). Three TBI severity groups were distinguished: mild TBI without risk factors for complicated TBI (mildRF- TBI, n = 22), mild TBI with ≥ 1 risk factor (mildRF+ TBI, n = 46) or moderate/severe TBI (n = 35). An experimental paradigm measured speed and accuracy of goal-directed behavior depending on: (1) visual identification; (2) visual localization; or (3) both, measuring visual integration. Group-differences on reaction time (RT) or accuracy were tracked down to task strategy, visual processing efficiency and extra-decisional processes (e.g. response execution) using diffusion model analysis. General neurocognitive functioning was measured by a Wechsler Intelligence Scale short form. Results The TBI group had poorer accuracy of visual identification and visual integration than the TC group (Ps ≤ .03; ds ≤ -0.40). Analyses differentiating TBI severity revealed that visual identification accuracy was impaired in the moderate/severe TBI group (P = .05, d = -0.50) and that visual integration accuracy was impaired in the mildRF+ TBI gro

Choledochal Malformation in Children: Lessons Learned from a Dutch National Study

Introduction: A choledochal malformation (CM) is a rare entity, especially in the Western world. We aimed to determine the incidence of CM in the Netherlands and the outcome of surgery for CM in childhood. Methods: All pediatric patients who underwent a surgical procedure for type I–IV CM between 1989 and 2014 were entered into the Netherlands Study group on choledochal cyst/malformation. Patients with type V CM were excluded from the present analysis. Symptoms, surgical details, short-term (30 days) complications were studied retrospectively. Results: Between January 1989 and December 2014, 91 pediatric patients underwent surgery for CM at a median age of 2.1 years (0.0–17.7 years). All patients underwent resection of the extrahepatic biliary tree with restoration of the continuity via Roux-en-Y hepaticojejunostomy. Twelve patients (12%) were operated laparoscopically. Short-term complications, mainly biliary leakage and cholangitis, occurred in 20 patients (22%), without significant correlations with weight or age at surgery or surgical approach. Long-term postoperative complications were mainly cholangitis (13%) and anastomotic stricture (4%). Eight patients (9%) required radiological intervention or additional surgery. Surgery before 1 year of age (OR 9.3) and laparoscopic surgery (OR 4.4) were associated with more postoperative long-term complications. We did not observe biliary malignancies during treatment or follow-up. Conclusion: Surgery for CM carries a significant short- and long-term morbidity. Given the low incidence, we would suggest that (laparoscopic) hepatobiliary surgery for CM should be performed in specialized pediatric surgical centers with a wide experience in laparoscopy and hepatobiliary surgery

Towards a standardised informed consent procedure for live donor nephrectomy: The PRINCE (Process of Informed Consent Evaluation) project-study protocol for a nationwide prospective cohort study

Introduction: Informed consent is mandatory for all (surgical) procedures, but it is even more important when it comes to living kidney donors undergoing surgery for the benefit of others. Donor education, leading to informed consent, needs to be carried out according to certain standards. Informed consent procedures for live donor nephrectomy vary per centre, and even per individual healthcare professional. The basis for a standardised, uniform surgical informed consent procedure for live donor nephrectomy can be created by assessing what information donors need to hear to prepare them for the operation and convalescence. Methods and analysis: The PRINCE (Process of In formed Consent Evaluation) project is a prospective, multicentre cohort study, to be carried out in all eight Dutch kidney transplant centres. Donor knowledge of the procedure and postoperative course will be evaluated by means of pop quizzes. A baseline cohort (prior to receiving any information from a member of the transplant team in one of the transplant centres) will be compared with a control group, the members of which receive the pop quiz on the day of admission for donor nephrectomy. Donor satisfaction will be evaluated for all donors who completed the admission pop-quiz. The primary end point is donor knowledge. In addition, those elements that have to be included in the standardized format informed consent procedure will be identified. Secondary end points are donor satisfaction, current informed consent practices in the different centres (eg, how many visits, which personnel, what kind of information is di

DCD kidney transplantation: results and measures to improve outcome.

Item does not contain fulltextPURPOSE OF REVIEW: The purpose of the present review is to describe the current kidney preservation techniques for donors after cardiac death and to give insight in new developments that may reduce warm ischemia times and therefore improve graft function after transplantation. RECENT FINDINGS: There is still a general reluctance to use donors after cardiac death for kidney donation and transplantation, because of a relatively high incidence of delayed graft function and primary nonfunction compared to conventional donors after brain death. New clinically applicable methods, such as automated chest compression devices and extracorporeal membrane oxygenation, may reduce warm ischemia time. SUMMARY: Kidneys from donors after cardiac death sustain an increased incidence of delayed graft function and primary nonfunction. However, transplanted kidneys that do not experience these complications survive as long as conventional kidneys from donors after brain death. Maintaining adequate organ perfusion after cardiac death by using automated chest compression devices and extracorporeal membrane oxygenation reduces warm ischemia time. Optimal organ preservation and careful selection of kidneys from donors after cardiac death may reduce the risk of delayed graft function and primary nonfunction. Major efforts should continue to be made to improve the quality of kidneys from donors after cardiac death and thereby expand the utilization of this large pool of donor kidneys to its full potential.1 april 201

Traumatic dissection and thrombosis of the popliteal artery in a child.

Injuries of the popliteal artery have the highest rate of limb loss compared with other peripheral vascular injuries. Particularly, blunt popliteal artery trauma is known to be associated with a high rate of amputation. Traumatic vascular injuries are usually associated with dislocations and fractures. We describe the radiographic findings as well as the delayed presentation and management of a crush injury of the left leg in an 8-year-old girl resulting in dissection of the popliteal artery without a dislocation or fracture
