In a first-in-human trial, SmartPAN hydrogel proved safe and easy to use for visualizing intraoperative pancreatic leakage during partial resections. Out of 29 patients receiving SmartPAN, 10 demonstrated positive leakage responses, with postoperative pancreatic fistula (POPF) occurring in 7 patients. Surgeons rated the device highly for its usability and expressed intent to use it frequently. […]

Multiservice machine learning models enhance surgical resource planning.
Multiservice machine learning models were developed to predict postsurgical length of stay (LOS) and discharge disposition at the time of case posting. An analysis of 63,574 patients showed the LOS model achieved an area under the curve (AUC) of 0.81. Incorporating relative value units and historical LOS improved prediction accuracy for both short and prolonged […]
Oligometastatic disease may benefit from aggressive multimodal therapy.
Oligometastatic patients with esophageal, gastro-esophageal junction, and gastric cancers experience improved outcomes with aggressive multimodal therapies. Research indicates that combining systemic therapy with surgical resection of primary tumors and metastases enhances prognosis. Notably, patients with oligometastatic cancer at the esophago-gastric junction showed potential for curative treatment. These findings suggest that current treatment paradigms should be […]
Immunotherapy expands treatment options for esophageal cancer.
Recent advancements in immunotherapy provide new treatment avenues for advanced esophageal cancer, particularly for squamous cell carcinoma and esophagogastric adenocarcinoma. Immune checkpoint inhibitors, such as nivolumab and pembrolizumab, are now approved in various treatment settings, including adjuvant therapy for patients post-surgery and first-line treatments combined with chemotherapy. These developments improve accessibility to effective therapies, regardless […]
Machine learning effectively predicts optimal outcomes in liver surgery
A machine learning model successfully predicted textbook outcomes in liver surgery using preoperative data from over 2,000 patients. The top-performing xgboost model achieved an area under the curve of 0.73. Significant predictors included minimally invasive techniques and patient characteristics such as lower comorbidity scores. Furthermore, meeting textbook outcome criteria was associated with improved overall survival, […]
Estrogen receptor-α influences muscle fibrosis and hernia development
Estrogen receptor-α ablation has been shown to reverse muscle fibrosis and prevent inguinal hernias, conditions affecting about 50% of men by age 75. Using a humanized mouse model, findings reveal how esr1 drives fibroblast proliferation and extracellular matrix deposition linked to hernia formation. Furthermore, pharmacological inhibition of esr1 restored normal muscle architecture and reversed existing […]
Machine learning effectively predicts discharge against medical advice
A study evaluated machine learning algorithms to predict discharge against medical advice for 48,394 injured inpatients over five years. Among these individuals, 8.8% opted for discharge against medical advice. The light gradient boosting machine combined with edited nearest neighbors outperformed traditional logistic regression, achieving areas under the curve of 0.820 and 0.837 in internal and […]
ETEP reduces post-operative pain compared to IPOM+ in hernia repair
Enhanced total extraperitoneal repair (ETEP) was compared with intraperitoneal onlay mesh repair-plus (IPOM+) for midline ventral hernia repair in a randomized trial involving 48 patients. Results indicated that ETEP had significantly longer operative times but resulted in notably lower pain scores at 6 and 24 hours, with fewer patients requiring rescue analgesia. Complications and recurrence […]
Conditional survival predictions enhance outcomes for pancreatic cancer patients
A study on pancreatic ductal adenocarcinoma reveals that conditional survival analysis based on kallikrein-related peptidase 7 (klk7) expression can significantly improve prognostic assessments. Results show that 1-, 2-, and 3-year conditional survival rates increased from 50.4% to 91.2%, while overall survival rates dropped from 81.9% to 38.6%. Patients surviving longer periods demonstrate improved future survival […]
Mindfulness interventions enhance surgeon well-being and performance
A scoping review assessed 24 studies on mindfulness-based interventions (MBIs) for surgeons, revealing that such programs are feasible and significantly improve mindfulness, reduce burnout, and enhance overall well-being. Notably, these interventions also boost executive function, surgical skills, and communication. Evidence was drawn from various study designs, including randomized control trials and qualitative research. Future research […]
