INTRODUCTION The main area of concern regarding radiofrequency ablation (RFA) of colorectal liver metastases is the risk of developing a local site recurrence (LSR). Reported accuracy of PET-CT in detecting LSR is high compared to morphological imaging alone, but no internationally accepted criteria for image interpretation have been defined. Our aim was to(More)
BACKGROUND The prognostic role of pericolic or perirectal isolated tumor deposits (ITDs) in node-negative colorectal cancer (CRC) patients is unclear. Rules to define ITDs as regional lymph node metastases changed in subsequent editions of the TNM staging without substantial evidence. Aim of this study was to investigate the correlation between ITDs and(More)
A decline in everyday cognitive functioning is important for diagnosing dementia. Informant questionnaires, such as the informant questionnaire on cognitive decline in the elderly (IQCODE), are used to measure this. Previously, conflicting results on the IQCODEs ability to discriminate between Alzheimer's disease (AD), mild cognitive impairment (MCI), and(More)
BACKGROUND Measuring impairments in "instrumental activities of daily living" (IADL) is important in dementia, but challenging due to the lack of reliable and valid instruments. We recently developed the Amsterdam Instrumental Activities of Daily Living Questionnaire (A-IADL-Q; note 1). We aim to investigate the diagnostic accuracy of the A-IADL-Q for(More)
INTRODUCTION We aimed to categorize laparoscopic rectal resections according to technical difficulty to standardize learning purposes and stratify results, making future studies more comparable. MATERIALS AND METHODS Fifty patients undergoing a laparoscopic total mesorectal excision were prospectively followed. Four preoperatively known facts (gender,(More)
BACKGROUND This study describes the validation of a new instrument measuring instrumental activities of daily living (IADL), the Amsterdam IADL Questionnaire© (a registered copyright of the Alzheimer Center of the VU University Medical Center). This informant-based tool aimed at detecting IADL problems in incipient dementia was previously found to have a(More)
BACKGROUND Complications after major abdominal surgery (MAS) are associated with increased morbidity and mortality. Rising costs in health care are of increasing interest and a major factor affecting hospital costs are postoperative complications. In this study, the costs associated with complications are assessed. METHODS Retrospective cohort study of(More)
INTRODUCTION Total mesorectal excision (TME) is an essential component of surgical management of rectal cancer. Both open and laparoscopic TME have been proven to be oncologically safe. However, it remains a challenge to achieve complete TME with clear circumferential resections margin (CRM) with the conventional transabdominal approach, particularly in mid(More)
BACKGROUND Over the last decades longevity has increased significantly, with more octogenarians undergoing surgery. Here, we assess surgical outcomes after major abdominal surgery in octogenarians. METHODS Observational cohort of 874 patients undergoing major abdominal elective surgery between January 2009 and March 2014. Seventy-six octogenarians were(More)
INTRODUCTION In The Netherlands there is no consensus about criteria for cancelling helicopter emergency medical services (HEMS) dispatches. This study assessed the ability of the primary HEMS dispatch criteria to identify major trauma patients. The predictive power of other early prehospital parameters was evaluated to design a safe triage model for HEMS(More)
