Core Tip
Core Tip: This retrospective study compared M-type dual-channel endoscopy combined with zebra guidewire lithotripsy vs conventional endoscopic methods for phytobezoar treatment. The combined technique significantly reduced procedure time (45.6 minutes vs 75.6 minutes) and hospital stay (5.9 days vs 7.1 days), achieved a 100% complete clearance rate, and lowered the overall complication rate to 4.65%. It demonstrates superior efficiency and safety, offering an optimized approach for endoscopic management of gastric phytobezoars.
