Dissecting para-aortic lymph nodes at station 16 is essential for prognostication in gastrointestinal, colorectal, and hepatobiliary cancers. A strategic approach involving duodenal mobilization, thermal fusion for chyle leak prevention, and careful dissection below the left renal vein ensures safe sampling and accurate risk stratification.

Virtual Formats Threaten Surgical Informed Consent’s Moral Ends
Virtual informed consent, adopted during the COVID-19 pandemic, persists despite its resolution, challenging the traditional “information-transfer” model. This study argues for a “trust-building” model, emphasizing the interpersonal and systemic aspects of consent. It explores the limitations of virtual formats in fulfilling this comprehensive understanding and proposes an ethical framework for physicians navigating this novel virtual […]
Validation of a Laparotomy Simulation Model for Surgical Training
Researchers assessed a simulated laparotomy incision and closure-training model using a quantitative study design. The model was found to be realistic and useful as a teaching tool, with strong content validity evidence. Experts outperformed novices in the evaluation. Pre and post-test assessments showed a significant increase in confidence levels, providing strong validity evidence for the […]
Impact of Hand Dominance on Laparoscopic Surgical Skills
Researchers found significant differences in skill acquisition and proficiency between dominant and non-dominant hands in laparoscopic surgical training. Network models and EMG data analysis effectively captured muscle activity and learning progression, suggesting the need for tailored training approaches. NASA-TLX scores correlated with performance, emphasizing the importance of objective and subjective measures in training. Personalized protocols […]
Increased Risk of Delirium after Non-Cardiac Surgery Linked to Preoperative Glucose Dysregulation
Preoperative glucose dysregulation, including hyperglycemia, hypoglycemia, or both, was associated with a higher incidence of delirium within 30 days after non-cardiac surgery. The hazard ratios for the development of delirium were increased in patients with hyperglycemia, hypoglycemia, and both types of dysregulation. Interestingly, hyperglycemia was consistently associated with postoperative delirium in all patients, regardless of […]
Improving End-of-Life Care for Veterans Undergoing Surgery
Researchers examined trends in end-of-life care services and satisfaction among veterans undergoing surgery. Over the study period, palliative care consultation and hospice use rates more than doubled, while satisfaction scores increased. Hospital location and accreditation were associated with the most significant changes. Improvements in satisfaction with end-of-life care corresponded with increased service usage, suggesting the […]
Privacy-Proof Live Surgery Streaming: Development of a Reliable Robotic Anonymization Algorithm
Researchers developed a pioneer surgical anonymization algorithm, validated across various robotic platforms, to remove out-of-body images in real-time. The algorithm successfully achieved a framewise anonymization roc auc-score of 99.46% on unseen procedures, increasing to 99.89% after post-processing. The deep learning model, ROBAN, offers safe real-time anonymization during complex surgical procedures on different robotic platforms, outperforming […]
Deficiencies in Reporting Clinical Significance in Contemporary CER
Contemporary Comparative Effectiveness Research (CER) often lacks explicit specification of clinically significant differences in study outcomes, as revealed in a systematic review of 307 studies from prominent medical journals. Only 8.5% of studies specified clinical significance, with 2.3% recommending changes in clinical decision-making based on statistical significance alone. Authors frequently defined clinical significance using validated […]
Procedure-Specific Risk of Postoperative Nausea
In a cross-sectional study analyzing data from 152 German and Austrian hospitals, researchers determined procedure-specific, risk-adjusted probabilities of postoperative nausea for 72 types of operations. The adjusted absolute risk ranged from 6.2% to 36.2%, with laparoscopic bariatric operations having the highest risk. Factors such as male sex, antiemetic prophylaxis, regional anesthesia, and preoperative opioids influenced […]
Wound Irrigation in Laparotomy: No Significant Reduction in Surgical Site Infections
Wound irrigation with polyhexanide solution did not significantly decrease the incidence of surgical site infections compared to saline or no irrigation after laparotomies. The study, involving 689 patients, found an overall infection rate of 11.8%, with no statistically significant difference between the groups. Further research is needed to assess the potential benefits in contaminated and […]
