Objectives: Endoscopic ultrasound-guided fine-needle aspiration/biopsy (EUS-FNA/B) is the gold standard for diagnosing gastric subepithelial lesions (SELs), but diagnosing lesions smaller than 20 mm remains challenging. We developed traction-assisted EUS-FNB (TA-EUS-FNB) using the clip-with-thread method to enhance diagnostic accuracy by stabilizing the lesion and providing counter-traction for easier needle access. This study evaluates the effectiveness of TA-EUS-FNB in diagnosing small gastric SELs.

Background: The long-term survival rate of patients with pancreatic ductal adenocarcinoma has improved alongside the development of multidisciplinary treatment, and there is now demand for less invasive surgery that maintains postoperative pancreatic function. We evaluated the efficacy of pancreas-preserving distal pancreatectomy in terms of oncologic parameters and postoperative pancreatic function.

Methods: The data of 98 consecutive patients who underwent distal pancreatectomy for the treatment of pancreatic ductal adenocarcinoma between 2012 and 2022 in our institution were retrospectively analyzed.

Background/aims: Although endoscopic ultrasound-guided hepaticogastrostomy (EUS-HGS) is performed globally, the procedure remains challenging. Guidewire manipulation is the most difficult step, and there are few reports on the factors associated with unsuccessful guidewire manipulation. This study aimed to assess the significance of the puncture angle on EUS images and identify the most effective guidewire rescue method for patients with unsuccessful guidewire manipulation.

Article Synopsis
  • This study investigates the use of endoscopic ultrasound-guided hepaticogastrostomy (EUS-HGS) specifically for treating malignant hilar biliary obstruction (MHBO), which hasn’t been thoroughly explored in previous research.
  • The research included 85 patients, showing an overall technical success rate of 87%, with challenges noted particularly for patients with a bile duct diameter of 4 mm or less.
  • Key findings reveal that technical failures often stem from issues like cholangiography difficulties and guidewire misplacement, indicating that EUS-HGS can be an effective but complex option for managing MHBO.
