Diagnostic Accuracy of Size‐Based Preoperative CT Assessment for Predicting Lymph Node Metastasis in Colon Cancer: A Systematic Review and Meta‐Analysis

Annals of Gastroenterological Surgery, EarlyView.
Preoperative CT based on lymph node size shows moderate accuracy for detecting nodal metastasis in colon cancer. In this meta‐analysis of 29 studies (5,634 patients), pooled sensitivity and specificity were 0.69 and 0.66. Size‐based CT alone has limited value for clinical decision‐making.

Extent of Lymph Node Dissection for cStage I Siewert Type I/II Cancers Based on Lymph Node Metastasis Risk Stratification

Annals of Gastroenterological Surgery, EarlyView.
ABSTRACT Aim The optimal surgical strategy and extent of lymph node (LN) dissection for clinical Stage I (cStage I) adenocarcinoma of the esophagogastric junction (AEG) remain controversial. This study aimed to evaluate surgical outcomes and clarify the prevalence and distribution of LN metastasis according to tumor characteristics in cStage I Siewert ...

Can Machine Learning Reduce Unnecessary Surgeries? A Retrospective Analysis Using Threshold Optimization to Prevent Negative Appendectomies in Adults

Annals of Gastroenterological Surgery, EarlyView.
Threshold‐optimized machine learning models using routine clinical and laboratory data in 623 adults undergoing appendectomy. Logistic regression (AUC = 0.765) and random forest (AUC = 0.785) were the best‐performing models for appendicitis detection and complicated appendicitis prediction, respectively.

Characteristics of Anal Fistula Cancer in Patients Who Underwent Surgery: A Nationwide Observational Study Using Diagnosis Procedure Combination Data

Annals of Gastroenterological Surgery, EarlyView.
The characteristics of patients with anal fistula cancer included a higher proportion of men, younger age, more smokers, and tumor‐related characteristics, including more advanced local progression. Surgical characteristics included a lower rate of minimally invasive surgery, a higher proportion of total pelvic exenterations, and longer postoperative ...

Comparison of Minimally Invasive Colectomy Between Intra‐ Versus Extra‐Corporeal Anastomosis Technique (COMMIT Study): Short‐Term Analysis

Annals of Gastroenterological Surgery, EarlyView.
This multicenter propensity score‐matched study of 3213 patients compared intracorporeal (IA) and extracorporeal (EA) anastomosis during minimally invasive colectomy. IA was associated with a significantly lower incidence of intraoperative blood loss ≥ 200 mL (2.5% vs.

Age‐Dependent Prognostic Significance of Preoperative Transthyretin After Curative Resection for Stage I–III Colorectal Cancer

Annals of Gastroenterological Surgery, EarlyView.
ABSTRACT Background Preoperative malnutrition and systemic inflammation are established determinants of adverse outcomes in colorectal cancer (CRC). Transthyretin (TTR), a rapid‐turnover hepatic protein, reflects both nutritional and inflammatory status; however, its clinical utility may be influenced by age‐ and sex‐related variability.

Impact of Postoperative Infectious Complications on Long‐Term Survival After Curative Resection for Colorectal Cancer: A Multicenter Study in the Minimally Invasive Era

Annals of Gastroenterological Surgery, EarlyView.
Postoperative infectious complications (PICs) have been associated with poor long‐term outcomes after colorectal cancer surgery, but evidence in the modern minimally invasive era remains limited. In this multicenter cohort of 5377 patients undergoing curative resection, PICs were independently associated with worse overall survival and relapse‐free ...

Interaction Between Operator and Assistant Certification Is Associated With Local Recurrence After Laparoscopic Rectal Cancer Surgery: An Ancillary Analysis of the EnSSURE Study

Annals of Gastroenterological Surgery, EarlyView.
A significant synergistic interaction between operator and assistant certification was associated with a lower risk of local recurrence after laparoscopic rectal cancer surgery. Patients treated by both ESSQS‐qualified operators and assistants had the lowest risk of local recurrence, whereas a single qualification alone was not associated with a ...

The Interoperability Challenge in DFT Workflows Across Implementations

Advanced Intelligent Discovery, EarlyView.
Interoperability and cross‐validation remain major challenges in the computational materials science. In this work, we introduce a common input/output standard that enables internal translation across multiple workflow managers—AiiDA, PerQueue, Pipeline Pilot, and SimStack—while producing results in a unified schema.
