A deep learning-based model was developed for real-time recognition of perigastric blood vessels during laparoscopic radical gastrectomy. In testing, the model demonstrated high precision (mean 0.9442) and recall (mean 0.9099) for arteries and maintained robust performance across various challenging conditions. It showed potential to improve intraoperative safety and reduce the risk of accidental bleeding, particularly […]

New nomogram model accurately predicts survival in gastric cancer patients
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, […]
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 […]
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 […]
Minimally invasive esophagectomy approaches show improved outcomes.
A significant trend toward minimally invasive esophagectomy (mie) and robotic-assisted minimally invasive esophagectomy (ramie) between 2010 and 2019 has been observed, with open esophagectomies (oe) declining by 52%. Mie utilization rose by 49% and ramie by 704%. Both mie and ramie demonstrated lower 30-day and 90-day mortality rates compared to oe, and higher five-year survival […]
High visceral fat area predicts intraoperative adverse events
A post hoc analysis involving 490 gastric cancer patients reveals that high preoperative visceral fat area (VFA) significantly increases the risk of intraoperative adverse events (IAEs) during laparoscopic gastrectomy. Specifically, IAEs occurred in 29% of the high VFA group, compared to 12% in the low VFA group. High VFA was identified as an independent risk […]
Deep learning model predicts early recurrence in gastric cancer
A new deep learning model utilizing multiphase CT images effectively predicts early recurrence in patients with locally advanced gastric cancer (LAGC). The model, integrated with clinical factors, demonstrated superior performance (AUC: 0.891) compared to previous models. Significant associations were found between higher prediction scores and tumor proliferation pathways, such as WNT and MYC signaling, as […]
Hiatal sling technique reduces liver injury in surgeries
The hiatal sling liver retraction technique has shown promising results in bariatric and upper gastrointestinal surgeries, significantly reducing liver enzyme elevation compared to the traditional Nathanson retractor. Among 1,874 surgeries, only two cases experienced difficulties, with no liver injuries or adverse effects reported. This technique offers adequate exposure while minimizing insults to the liver, enhancing […]
Advanced MRI strategies improve diagnostic accuracy in gastric cancer
Multiparametric MRI (mpmri) demonstrated superior diagnostic accuracy for restaging locally advanced gastric cancer after neoadjuvant therapy, with significant inter-reader agreement noted. The accuracy for T restaging reached 0.586 for mpmri, outperforming other imaging methods. Importantly, mpmri achieved an area under the curve of 0.879 for distinguishing patients with good responses to neoadjuvant treatment, highlighting its […]
