A novel nomogram has been developed to predict postoperative pneumonia risk after esophageal endoscopic submucosal dissection (ESD). In a cohort of 492 patients, the incidence of pneumonia was 18.6%. Key predictive factors included female sex, older age, low serum albumin levels, prolonged operative duration, muscular layer damage, and comorbid pulmonary diseases. The nomogram exhibited robust […]

Tumor downstaging improves survival in esophageal adenocarcinoma patients
Analysis of 6,400 esophageal adenocarcinoma patients revealed that 51% experienced tumor downstaging after neoadjuvant chemoradiation, with complete downstaging noted in 5%. Downstaging correlated with a 31% and 17% reduced risk of death compared to disease progression and stable staging, respectively. Additionally, robotic-assisted minimally invasive esophagectomy reduced mortality risk by 17% compared to open surgery, while […]
Risk model predicts surgical adverse events in esophagectomy patients
A risk stratification model for surgical adverse events (SAEs) in minimally invasive esophagectomy (MIE) was developed and validated using data from 747 patients. The model identified key risk factors, including chronic obstructive pulmonary disease and low albumin levels, achieving areas under the curve of 0.889 and 0.793 for the training and validation sets, respectively. Patients […]
DCNN Model Enhances Early Gastric Cancer Diagnosis
A study established a deep convolutional neural network (DCNN) system that significantly improved diagnostic accuracy for early gastric cancer (EGC). In independent tests, the model achieved an area under the curve (AUC) of 0.917 and sensitivity of 93.38% for image datasets, while video tests showed an AUC of 0.930 and 96.92% sensitivity. Novice endoscopists reached […]
Surgical Trends and Outcomes in Korean Gastric Cancer Patients
The 2023 nationwide survey by the Korean Gastric Cancer Association revealed that early gastric cancer comprised 63.1% of cases. Notably, the mean patient age increased to 64.6 years, with those aged ≥71 rising to 31.7% since 1995. The use of totally laparoscopic surgery was predominant at 63.2%, with robotic techniques growing to 9.5%. Post-operative mortality […]
Updated gastric cancer guidelines enhance multidisciplinary treatment approaches
The 2024 Korean Practice Guidelines for Gastric Cancer present significant updates, particularly in systemic treatment, following a thorough review by an interdisciplinary team. Six key questions were revised, and seven statements developed based on extensive systematic reviews and recent research. The updated guidelines aim to enhance the quality of care, with recommendations categorized by evidence […]
Function-Preserving Gastrectomy Improves Quality of Life
Function-preserving gastrectomy (FPG) techniques, such as pylorus-preserving and proximal gastrectomy, effectively balance oncological safety while enhancing patients’ quality of life (QoL) following early gastric cancer treatment. These methods yield comparable oncological outcomes to traditional surgery and promote better nutritional recovery with fewer gastrointestinal issues. However, the adoption of FPG remains impacted by its technical complexity […]
New prognostic model enhances survival predictions for esophageal carcinoma
The study developed a novel prognostic model for overall survival in esophageal carcinoma (EC) patients, incorporating nine significant predictors, including body mass index and treatment modalities. Tested on 3,127 patients, the model achieved a c-index of 0.715 in training and 0.711 in validation cohorts. Area under the curve scores for 1, 3, and 5-year survival […]
Laparoscopic repair outperforms traditional methods for gastric ulcers.
The study reveals that laparoscopic omental patch repair (LOPR) offers significant advantages for treating Helicobacter pylori-associated gastric ulcers with perforations. Patients undergoing LOPR demonstrated reduced operative time, less intraoperative blood loss, and quicker postoperative recovery compared to those receiving the Graham patch technique. Additionally, LOPR resulted in lower rates of postoperative complications and recurrence. Overall, […]
Bolus exposure predicts symptom relief after laparoscopic surgery.
Bolus exposure demonstrated superior predictive capability for postoperative symptom resolution in patients undergoing laparoscopic Nissen fundoplication, outshining traditional acid-based parameters. In a cohort of 72 gastroesophageal reflux disease patients, its diagnostic accuracy reached 0.981 for regurgitation and 0.723 for epigastric pain. Secondary analyses in patients without pathological reflux confirmed bolus exposure’s effectiveness across various symptoms, […]
