The study analyzed surgeons’ hand movements to characterize the differences in movement efficiency between experienced and novice surgeons. Hand motions were recorded using an inertial measurement unit (IMU) during a simulated surgical procedure. The results showed that experienced surgeons exhibited more fluid and efficient hand movements compared to novice surgeons. The angle of roll motion, […]

Predicting Surgical Complications in Colonic Neoplasia Patients Using Machine Learning
A study investigated the utility of machine learning algorithms in predicting complications for patients undergoing colectomy for colonic neoplasia. The three machine learning models successfully identified patients who developed complications, with the neural network scoring highest in predicting anastomotic leak, prolonged length of stay, and inpatient mortality. Although differences in model performance were largely insignificant, […]
Machine Learning Enhances Early Gastric Cancer Identification
The systematic review and meta-analysis found that machine learning-based models have greater performance in the identification of early gastric cancer (EGC) compared to non-specialist clinicians. The sensitivity, specificity, and summary receiver operating characteristic (SROC) of the machine learning models were higher than those of non-specialist clinicians. With the assistance of machine learning models, the diagnostic […]
AI’s Pivotal Role in Accelerating Clinical Trials and Medical Breakthroughs
Revolutionizing clinical trials, AI enables expedited and streamlined processes through automated data generation and management. It interprets data, facilitates biosimulation and early disease diagnosis, and reduces costs and time while improving efficiency and drug development research. The study highlights how AI revolutionizes data collection methods and overcomes challenges in clinical trials, emphasizing its noteworthy implications […]
Evaluating the Performance of GPT-4 on Surgical Knowledge Assessments
Large language model GPT-4, specifically the chatbot version ChatGPT, demonstrates near or above human-level performance on surgical knowledge assessments from two widely used question banks. In open-ended questions, ChatGPT answers accurately to 47.9% and 66.1% of questions, while for multiple-choice questions, it achieves accuracy rates of 71.3% and 67.9%. However, inconsistencies in responses on repeat […]
Examining Surgical Team Member Adaptation to Uncertainty Using the Operating Room Black Box
Results from this observational study using the Operating Room Black Box demonstrated how surgical team members adapt their teamwork skills during instances of uncertainty, specifically when dealing with intraoperative adverse events (IAEs). Nurses exhibited increased backup behavior skills during IAEs, while surgeons and medical trainees expressed more psychological safety skills. However, all roles exhibited fewer […]
Intraoperative Autonomic Physiology in Surgeons: Real-time Cardiac Reactivity Study
Surgeons’ autonomic physiology, specifically their heart rate (interbeat intervals), varies intraoperatively. Attending surgeons exhibit higher heart rate reactivity during high-risk operations, while residents show lower reactivity during high-risk procedures relative to low-risk ones. Nurses respond similarly during both low-risk and high-risk operations; however, they are more reactive when the resident is operating. Attending surgeons’ physiological […]
Impact of Stoma App on Quality of Life in Stoma Patients
A randomized double-blind clinical trial investigated the effects of a mobile healthcare app, Stoma App, on the quality of life in stoma patients. The intervention group, using the full version of the app with personalized guidance and peer support, reported a significant 3.1-point improvement in stoma-related quality of life one month after surgery. However, no […]
Telehealth Follow-Up After General Surgery Procedures is Safe and Effective: Study Highlights Lower Complication Rates
Telehealth utilization for postoperative care in general surgery has rapidly increased during the pandemic, but its usage among the veteran surgical population remains limited. A retrospective review of veterans undergoing general surgery found that telehealth follow-up after qualifying procedures was safe and effective. Among the 1075 patients included in the study, 56% followed up in-person […]
Telehealth intervention shows potential to improve quality of life for patients with eating symptoms after gastroesophageal cancer surgery
Researchers conducted a pilot study to assess the effectiveness of a telehealth intervention for personalized self-management of eating symptoms after gastroesophageal cancer surgery. The intervention, delivered by a nutritionist through telehealth sessions over 4 months, demonstrated feasibility and acceptability among patients. Although the differences between the intervention and control groups were not statistically significant, the […]
