The aim of this study was to characterize hospital-level variation and establish diagnostic performance benchmarks for postoperative imaging in children with complicated appendicitis. ⋯ Significant variation exists across hospitals in imaging practices to diagnose suspected OSI following appendectomy. Imaging utilization benchmarking may assist hospitals in prioritizing quality improvement efforts to optimize resource utilization and radiation stewardship.

The aim of this study was to evaluate the outcome of endoscopic resection (ER) versus esophagectomy in node-negative cT1a and cT1b esophageal adenocarcinoma. ⋯ This study demonstrates ER has comparable long-term outcomes for clinical T1aN0 and T1bN0 esophageal adenocarcinoma. However, 15% of patients with cT1b esophageal cancer were found to have positive nodal disease. Future research should seek to identify the subset of T1b cancers at high risk of nodal metastasis and thus would benefit from esophagectomy with lymphadenectomy.

The aim of this study was to build a SVM classifier using ResNet-3D algorithm by artificial intelligence for prediction of synchronous PC. ⋯ The ResNet3D + SVM classifier based on deep learning algorithm using ResNet-3D framework has shown great potential in prediction of synchronous PC in CRC.

To examine the prevalence of frailty in surgical patients and determine whether age and sex modify the relationship between frailty and long-term mortality. ⋯ We observed a high prevalence of frailty in patients undergoing cardiac surgery, and a statistically significant association between frailty and long-term mortality after cardiac procedures. Importantly, the rate of death was inversely proportional to age, such that frailty had a stronger adverse impact on younger patients. Our findings highlight the need to incorporate frailty into the preoperative risk stratification and investigate strategies to support younger patients who are frail.

This study aimed to investigate transitions of recurrence hazard and peak recurrence time in patients with nonmetastatic CRC using the hazard function. ⋯ Changes in recurrence hazard for CRC patients varied considerably by stage. Our findings suggest that short-interval surveillance might be unnecessary for stage I patients for the first 3 years after surgery, whereas short-interval surveillance for the first 3 years should be considered for stage III patients.
