Enhanced Lymph Node Retrieval in Left-Sided Colorectal Cancer with Indocyanine Green Fluorescence Imaging

This preliminary study showed that indocyanine green (ICG) fluorescence imaging-guided laparoscopic para-aortic lymphadenectomy in left-sided colorectal cancer patients resulted in increased retrieval of total lymph nodes, including inferior mesenteric artery and para-aortic lymph nodes. ICG imaging may improve the completeness of lymph node dissection without significantly affecting complications.

Predictive Model for Postoperative Delirium in Elderly Abdominal Cancer Patients Using SMOTE

A synthetic minority oversampling technique (SMOTE)-based model was developed to predict postoperative delirium in elderly patients with abdominal malignancies. In this cohort of 611 patients, risk factors for delirium included Charlson comorbidity index, American Society of Anesthesiologists classification, history of cerebrovascular disease, surgical duration, perioperative blood transfusion, and postoperative pain score. The SMOTE-based predictive model demonstrated comparable performance to traditional methods, with an area under the curve of 0.856, suggesting it effectively addresses data imbalance.

Impact of Surgeon Age on Long-Term Survival After Gastrectomy

In this population-based cohort study involving 1,647 patients undergoing gastrectomy for gastric adenocarcinoma, surgeon age ≥47 years was associated with worse 5-year all-cause mortality rates. Adjusted hazard ratios for surgeons aged 55+ were 1.21 (95% CI 1.04 to 1.41), and for those aged 47-54 were 1.16 (95% CI 0.99 to 1.36), compared with those aged ≤46 years. The associations became non-significant after adjusting for lymph node yield, resection margin status, and complications, suggesting these factors may mediate the impact of surgeon age on long-term survival.

Benefits of Microencapsulated Sodium Butyrate for Gastrointestinal Health

Microencapsulated sodium butyrate, a stable form of the compound, is gaining attention for its potential use in gastrointestinal disease prevention and treatment. It offers energy to the large intestine, supports intestinal epithelium integrity, and stimulates the immune system. This review discusses its use from both surgical and gastroenterological perspectives, highlighting its role in prehabilitation, perioperative treatment, and local application. There is increasing evidence supporting sodium butyrate’s effectiveness in various gastrointestinal health areas.

Improved Overall Survival with Portal and Hepatic Vein Embolization in Liver Resection

Comparing portal vein embolization (PVE) with simultaneous portal and hepatic vein embolization (PVE/HVE) in liver cancer patients showed significantly higher overall survival with PVE/HVE. The study demonstrated a longer 3-year overall survival in the PVE/HVE group compared to PVE alone, making PVE/HVE an independent predictor of survival in primary and secondary liver cancer cases.

Accuracy and Clinical Correlation of AI-based Computer Vision in Laparoscopic Appendectomy

Implementation of an AI-based computer-vision model in laparoscopic appendectomy accurately assesses complexity grading and safety adherence, predicting operative time and intraoperative course. However, no clinical correlation is found regarding postoperative outcomes. Surgeons and inter-surgeons agreements were high for complexity grading and safety adherence. Further studies are needed to validate these findings.

Advancements in Endoscopic Cryotherapy in Gastrointestinal Diseases

Endoscopic cryotherapy has shown safety and efficacy in treating gastrointestinal conditions, including complete eradication of dysplasia and neoplasia in Barrett’s esophagus. It serves as a second-line treatment for refractory cases and an alternative to surgical resection for duodenal adenomas. Innovative applications for gastrointestinal bleeding and esophageal strictures have also been reported. Overall, endoscopic cryotherapy is a safe and effective therapeutic option with ongoing research exploring additional clinical indications.

Robotic D3-D4 Lymphadenectomy Improves Survival in Upper Rectum and Sigmoid Colon Cancer Patients

Standardized robotic D3-D4 lymphadenectomy improves survival in upper rectum and sigmoid colon cancer patients with more than N2 lymph node metastasis. Specific nodal stations contribute differently to overall survival, with common iliac vessels and infra-renal vein being significant predictors. Results suggest optimized surgical techniques and potential updates to treatment guidelines.

Improved Skill Transfer with 3D-Printed Model for Laparoscopic Biliary-Enteric Anastomosis Training

A randomized controlled trial found that training with a 3D-printed model for laparoscopic biliary-enteric anastomosis led to significantly shorter operation times, higher performance scores, and greater goal achievement compared to traditional training methods. This suggests improved skill acquisition and transferability to a clinical setting with the novel simulation model.

Machine Learning Models to Predict Laparoscopic Surgery Difficulty in Rectal Cancer

Researchers developed and validated machine learning (ML) models to predict the difficulty of laparoscopic total mesorectal excision (LaTME) in rectal cancer. In a study with 186 patients, four ML models—logistic regression (LR), support vector machine (SVM), random forest (RF), and decision tree (DT)—were developed using preoperative and intraoperative factors. All models showed strong performance in predicting surgical difficulty, with SVM achieving the highest area under the receiver operating characteristic curve (AUC = 0.987). A logistic regression-based nomogram was also created, incorporating key predictive factors like body mass index (BMI), tumor diameter, and comorbid hypertension, providing surgeons with a visual tool to assess surgical difficulty.
