A newly developed nomogram model provides effective predictions for overall survival in gastric carcinoma patients. Based on analysis of data from 2018 to 2020, ten independent prognostic factors, including body mass index and TNM stage, were identified. The model demonstrated strong predictive capacity, with AUC values nearing 0.85 for 1-year survival in both training and […]

Enhanced lymph node dissection improves outcomes in gastric adenocarcinoma patients
Findings indicate that lymph node dissection (LND) during upfront gastrectomy significantly impacts prognostic outcomes for gastric adenocarcinoma (GAC) patients. The study recommends total lymph node (TLN) counts of ≥18 for detecting positive nodes and ≥23 for identifying N3 status. Furthermore, a negative lymph node count (NLN) >9 correlates with better survival in N+ GAC patients, […]
Video grading predicts bile leak risk in robotic surgeries
Bile leak rates post-robotic pancreatoduodenectomy are substantially reduced when surgical performance is graded. In a multicenter study of 259 patients, an objective structured assessment of technical skills (OSATS) score greater than 21 was linked to a 59.2% relative reduction in bile leaks, with rates decreasing from 12.5% to 5.1%. Additionally, a significant learning curve was […]
Combined bowel preparation significantly improves colostomy reversal outcomes.
A recent analysis of the NSQIP database identified 793 adults undergoing elective colostomy reversal. Those receiving combined oral antibiotic and mechanical bowel preparation experienced markedly reduced rates of infectious complications, anastomotic leaks, and longer hospital stays compared to other groups. Multivariate analysis indicated that this approach lowered the odds of these adverse outcomes (adjusted odds […]
Intraoperative blood loss impacts morbidity after liver surgery
Among 2,491 patients undergoing liver cancer surgery, significant associations were found between adjusted blood loss (ABL) and postoperative complications. Patients with ABL below 8.5 ml/kg experienced a lower comprehensive complication index (CCI) of 10.6 compared to 15.2 in those with higher ABL (p < 0.001). A nonlinear correlation indicated CCI increases sharply beyond 10 ml/kg, […]
A predictive nomogram effectively identifies high-risk patients for cr-popf.
A novel nomogram utilizing preoperative factors has been developed to predict clinically relevant postoperative pancreatic fistula (cr-popf) following pancreaticoduodenectomy. The nomogram, based on 262 patient data, identified key risk factors such as triglycerides and pancreatic duct size. With an area under the curve of 0.812 during validation and strong calibration, it achieved sensitivities of 60.9% […]
High glycemic variability increases risk of postoperative complications.
High glycemic variability on the first postoperative day significantly correlates with increased risk for infection-related complications in gastrointestinal cancer patients undergoing radical surgery. A study of 438 patients identified elevated glycemic levels, high leukocyte counts on the fourth postoperative day, and alcohol consumption as independent risk factors. Utilizing machine learning, researchers developed three effective nomogram […]
Venous thromboembolism poses high mortality risk post-cancer surgery
A nationwide study found that 90-day postoperative venous thromboembolism rates were 6.1% for liver and 6.7% for pancreatic surgeries. Key risk factors included major hepatectomy, left pancreatectomy, obesity, and prior thromboembolism history. By one year, pancreatic surgery patients had a significantly higher cumulative incidence (9.8%) compared to liver surgery patients (7.0%). Patients experiencing venous thromboembolism […]
Video-based coaching significantly enhances surgical skill acquisition.
A meta-analysis of 15 studies with 382 participants reveals that video-based coaching (VBC) markedly improves surgical technical skills. Participants who received VBC scored significantly higher than controls, with average performance scores showing a standardized mean difference of 0.71. Additionally, improvement from baseline to final performance also demonstrated a significant standard mean difference of 0.98. The […]
Conditional survival improves significantly after gastrectomy for gastric cancer
In a cohort of 1,129 gastric cancer patients undergoing curative gastrectomy, distinct improvements in conditional survival (CS) were observed over 10 years, particularly in stages II and III. The 5-year disease-specific survival rates consistently increased. Notably, survival rates for disease-specific causes intersected for stage II at 7 years and stage III at 8 years. Factors […]
