Augmented reality in liver surgery reduces intraoperative bleeding and complications. Blood loss decreased by 75.9 ml (p < 0.001) with AR guidance. Transfusion rates dropped to nearly half (RR: 0.47; p = 0.01); fewer complications (RR: 0.64; p = 0.009). AR-assisted techniques could improve surgical precision and patient outcomes, particularly in tumor cases. Tumor recurrence […]

Reduce Costs and Carbon Footprint in Laparoscopic Cholecystectomy
Switching to reusable instruments in laparoscopic cholecystectomy can significantly cut costs and emissions. Implementing reusable trocars and clip applicators can lower emissions by 9.5 kg CO₂-eq. per procedure (-21%) and lead to cost savings in over 93% of scenarios. Total interventions yield a 36% reduction in carbon footprint (16.5 kg CO₂-eq. per procedure). Adopting these […]
Early Cholecystostomy Reduces Risks in High-Risk Patients
Timing matters in acute calculous cholecystitis, particularly for high-risk patients. Percutaneous cholecystostomy within 48 hours leads to a shorter stay: 7 days vs. 13 days (p<0.001). Mortality drops significantly when performed early: 5.9% at 90 days vs. 22.6% (p=0.037). Delayed procedures linked to 4.80 times higher odds of longer hospital stays. Early intervention can significantly […]
Effective Suturing for Bile Leaks in Laparoscopic Hepatectomy
A new suturing technique using LapraTy® suture clips shows promise for managing intraoperative bile leaks during laparoscopic surgery. Rapid closure of bile leaks without excessive tension is possible, reducing risk of tissue damage. Omental coverage may help prevent postoperative bile leakage and improve outcomes. This technique is particularly valuable in challenging surgical situations and enhances […]
Tailored Preoperative Risk Strategies Enhance Colorectal Surgery Safety
This study highlights the shift toward risk stratification in preoperative assessments for colorectal surgery to improve outcomes. Broad testing in healthy patients shows minimal benefit and high costs. A tailored, evidence-based approach reduces major adverse cardiac events. Surgeons should implement risk-specific evaluations to optimize patient selection and minimize operative risks. Guidelines are recommended to impact […]
Refined Prognostic Tool for Esophageal Cancer
A new lymph node ratio-based staging system improves survival prediction for esophageal squamous cell carcinoma (ESCC). The proposed SRRN system correlates with 5-year overall survival rates: 66.7% for SRRN0 vs. 7.9% for SRRN3. SRRN outperforms traditional N staging, showing higher accuracy in both Cox and RSF models, enhancing prognostic reliability. This method could refine patient […]
Impact of T and N Stages on Survival in Stage IV Colorectal Cancer
Advanced T and N stages significantly worsen survival in stage IV colorectal cancer, highlighting the need for careful patient stratification. 5-year cancer-specific survival (CSS) is just 20.7%, dropping to 17.4% for T4 and 14.5% for N2. Higher T and N stages independently increase mortality risk, with T4 (HR: 1.33) and N1/N2 (HR: 1.27 and 1.59) […]
Cost Savings with Enhanced Recovery in Colorectal Surgery
Colorectal enhanced recovery after surgery (ERAS) significantly reduces costs and complications compared to conventional care. ERAS leads to a median cost reduction of AUD 2010 per patient (AUD 20,719 vs. AUD 22,729, p=0.008). Patients on ERAS had a shorter median length of stay (5 vs. 6 days, p<0.001) and lower overall complication rates (26.42% vs. […]
New AI Model Predicts Cardiac Risks in Surgery
A new deep learning model predicts postoperative cardiac events after noncardiac surgery with high accuracy, improving patient safety. The model showed an AUROC of 0.902 for 30-day major adverse cardiac and cerebrovascular events (MACCE), outperforming traditional methods. Only 0.6% of 165,577 patients experienced MACCE, indicating the model’s focus on high-risk patients may enhance targeting for […]
Machine learning predicts complications in acute cholecystitis
Machine learning tools can now help surgeons assess the risk of postoperative complications in acute calculous cholecystitis patients. Cholesurgrisk I achieved an AUC-ROC of 0.8456, while Cholesurgrisk II, which includes intraoperative data, improved this to 0.8903. A web-based version of Cholesurgrisk I offers real-time, patient-specific risk estimates. Integrating these models into practice could enhance preoperative […]
