Two Days Versus Five Days of Postoperative Antibiotics for Complex Appendicitis: Cost Analysis of a Randomized, Noninferiority Trial.

Objective: To compare costs for 2 days versus 5 days of postoperative antibiotics within the antibiotics after an aPPendectomy In Complex appendicitis trial.Background:Recent studies suggest that restrictive antibiotic use leads to a significant reduction in hospital stays without compromising patient safety. Its potential effect on societal costs remains underexplored.

2 days versus 5 days of postoperative antibiotics for complex appendicitis: a pragmatic, open-label, multicentre, non-inferiority randomised trial.

Background: The appropriate duration of postoperative antibiotics for complex appendicitis is unclear. The increasing global threat of antimicrobial resistance warrants restrictive antibiotic use, which could also reduce side-effects, length of hospital stay, and costs.

Methods: In this pragmatic, open-label, non-inferiority trial in 15 hospitals in the Netherlands, patients with complex appendicitis (aged ≥8 years) were randomly assigned (1:1) to receive 2 days or 5 days of intravenous antibiotics after appendicectomy.

Selection of patients for hepatic surgery of colorectal cancer liver metastasis based on genomic aberrations.

Background: We investigated whether genomic aberrations in primary colorectal cancer (CRC) can identify patients who are at increased risk of developing additional hepatic recurrence after colorectal liver metastases (CLM) resection.

Methods: Primary tumour DNA from 79 CLM resected patients was analysed for recurrent copy number changes (12x135k NimbleGen(™) aCGH). The cohort was divided into three groups: CLM patients with a recurrence-free survival after hepatic resection of at least 5 years (n = 21), patients who developed intra-hepatic recurrence (n = 32), and patients who developed extrahepatic recurrence (n = 26).

Evaluation of image registration in PET/CT of the liver and recommendations for optimized imaging.

Unlabelled: Multimodality PET/CT of the liver can be performed with an integrated (hybrid) PET/CT scanner or with software fusion of dedicated PET and CT. Accurate anatomic correlation and good image quality of both modalities are important prerequisites, regardless of the applied method. Registration accuracy is influenced by breathing motion differences on PET and CT, which may also have impact on (attenuation correction-related) artifacts, especially in the upper abdomen.
