Nomogram effectively predicts postoperative pneumonia post-esophageal ESD

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 […]

EUS-directed approach resolves jaundice in patients with obstructions

A novel EUS-guided technique utilizing lumen-apposing metal stents effectively treated patients with concomitant gastric outlet and biliary obstructions. In a study involving nine severely ill individuals, complete resolution of jaundice was achieved in all cases, attributed to successful transduodenal ERCP via gastroduodenal stenting. Post-procedure evaluations showed significant improvements in gastric outlet obstruction scores across all […]

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 […]

New Techniques Enhance Endoscopic Treatment for Gastric Tumors

Recent advancements in peroral flexible endoscopy improve approaches to managing gastric subepithelial tumors (SETs) with malignant potential. Resection techniques depend on tumor size, with options like endoscopic mucosal resection for superficial lesions and endoscopic enucleation for small tumors. When full-thickness resection is complex, laparoscopic and endoscopic cooperative surgery provides a viable alternative. High caution is […]

Endoscopic characterization outperforms biopsies in treatment planning

Effective endoscopic characterization for colorectal lesions >2 cm leads to better treatment outcomes compared to non-targeted and targeted biopsies. In a study of 84 patients, endoscopic methods proposed adequate treatment in 52.3 to 70.5% of cases, while biopsies resulted in 72.7% and 69.3% respectively. However, biopsy strategies risk under-treatment in nearly a third of cases, […]

Revised predictive model shows improved accuracy for post-ERCP pancreatitis

A new predictive model for post-endoscopic retrograde cholangiopancreatography (ERCP) pancreatitis has been developed, highlighting procedural factors such as total procedure time, unintended pancreatic duct cannulation, and pancreatic opacification as significant risks. Among 1,112 patients, the model stratified participants into low, intermediate, and high-risk groups, revealing pancreatitis incidences of 2.6%, 7.1%, and 12.6%, respectively. This revised […]

Modified suturing technique achieves high closure rate in duodenal ESD

A modified double-layered suturing method, known as the origami method, demonstrated a 96% success rate in achieving complete closure of large mucosal defects following duodenal endoscopic submucosal dissection (ESD). In a review of 28 cases, closure was completed with a median time of 16 minutes, and no complications such as perforations or bleeding were observed. […]

Key predictors identified for successful outcomes in gastroparesis treatment

A systematic review of 1,899 articles identified 30 relevant studies on gastric peroral endoscopic myotomy (GPOEM) for refractory gastroparesis. Findings revealed a GPOEM response rate of 63.1%. Key predictors for a positive response included older age, shorter gastroparesis duration, nondiabetic etiology, lower body mass index, and previous improvement with intrapyloric botulinum toxin. However, variability in […]

Cold snare polypectomy shows superior safety for small polyps

A comparison of polypectomy techniques reveals that cold snare polypectomy (CSP) offers a significantly safer alternative to hot snare polypectomy (HSP) for polyps under 10 mm. While both methods have similar efficacy, CSP reduces risks of adverse events like bleeding and perforation. With most colorectal polyps being less than this size, adopting CSP could notably […]

Orthodontic rubber bands enhance colorectal ESD training efficiency

Orthodontic rubber band-assisted colorectal endoscopic submucosal dissection (ORB-ESD) significantly improved trainees’ procedure times, matching expert levels. The study found that ORB-ESD shortened colorectal ESD procedure duration (28.0 min) compared to conventional methods (41.0 min). Furthermore, resection speed, visual field exposure, and muscle injury rates were better in the ORB-ESD group compared to conventional trainees, suggesting […]
