The diagnostic performance of combined conventional cytology with smears and cell block preparation obtained from endoscopic ultrasound-guided fine needle aspiration for intra-abdominal mass lesions.

Background/aim: Endoscopic ultrasound-guided fine needle aspiration (EUS-FNA) is the primary method for tissue acquisition of intra-abdominal masses. However, the main limitation of cytology alone is the lack of tissue architecture and inadequate samples. This study aimed to evaluate the diagnostic performance of combined conventional cytology and cell block preparation obtained from EUS-FNA of intra-abdominal masses without Rapid On-site Evaluation (ROSE).

Effectiveness and Safety of a Single 7-French Plastic Stent for Endoscopic Ultrasound-guided Pancreatic Pseudocyst Drainage and Long-term Follow-up Outcomes.

Background: Endoscopic ultrasound (EUS)-guided cystogastrostomy with a single 7-French (Fr) double-pigtail stent (DPS) is less popular due to the concern of stent patency. We aimed to assess the effectiveness, complications, and long-term outcomes of a single 7-Fr DPS in the endoscopic drainage of uncomplicated pseudocysts, containing no or minimal (<10%) debris.

Methods: A retrospective review of patients with pancreatic pseudocysts, who underwent EUS-guided cystogastrostomy during 2010-2018, and a systematic review of the literature were conducted.
