Cyanoacrylate glue is a medical adhesive commonly used in the treatment of gastric varices, particularly in patients with cirrhosis who are experiencing variceal bleeding. Gastric varices are dilated veins in the stomach, which can rupture and lead to life-threatening bleeding.
Cyanoacrylate glue is a medical adhesive commonly used in the treatment of gastric varices, particularly in patients with cirrhosis who are experiencing variceal bleeding. Gastric varices are dilated veins in the stomach, which can rupture and lead to life-threatening bleeding. Cyanoacrylate glue is injected endoscopically into the varices to achieve hemostasis by rapidly solidifying upon contact with blood, thereby sealing the bleeding vessels.
A randomized controlled trial compared two strategies for cyanoacrylate therapy in patients with cirrhosis and large gastric varices experiencing their first variceal bleed: aggressive and conservative approaches. In the aggressive approach, all visible gastric varices were obliterated with cyanoacrylate glue, while in the conservative approach, only varices with high-risk features or signs of recent bleeding were treated.
The study found that both approaches had similar outcomes in terms of 1-year variceal rebleeding rates (18.2% for aggressive vs. 15.0% for conservative) and all-cause mortality (22.2% vs. 32.9%, respectively). Aggressive therapy, however, achieved faster obliteration of varices and required fewer endoscopic sessions. Adverse event rates were comparable between the two groups.
In conclusion, while aggressive cyanoacrylate therapy may expedite variceal obliteration, its clinical outcomes are similar to those of conservative therapy, making both approaches viable options depending on patient needs.
Introduction: Endoscopic metabolic therapies have emerged as less invasive alternatives to bariatric surgery for patients with obesity and poorly controlled type 2 diabetes mellitus (T2DM). The EndoBarrier duodenal-jejunal bypass liner (DJBL) is an endoscopically placed...
Introduction: Endoscopic ultrasound (EUS)-guided transmural drainage is the standard minimally invasive treatment for symptomatic necrotizing pancreatitis. However, the optimal timing of direct endoscopic necrosectomy (DEN) following drainage remains uncertain. While the conventional step-up approach reserves...
Introduction: Bevacizumab is widely used in metastatic colorectal cancer (mCRC) because of its survival benefits but is associated with impaired wound healing, gastrointestinal perforation, and bleeding. These concerns often lead clinicians to delay endoscopic procedures...
Introduction: Endoscopic submucosal dissection (ESD) enables en bloc resection of large colorectal neoplasms with excellent oncological outcomes. However, concerns about perforation have limited its widespread adoption. This large prospective multicenter study evaluated the incidence, risk...
Introduction: Obesity has become one of the greatest global health challenges. New incretin-based therapies—including semaglutide, tirzepatide, resmetirom, and SGLT2 inhibitors such as empagliflozin—have transformed the treatment of obesity, diabetes, and MASLD. However, many patients discontinue...
Introduction: Endoscopic ultrasound-guided fine-needle biopsy (EUS-FNB) is the standard technique for diagnosing solid pancreatic lesions. Traditionally, biopsy specimens are processed for cytology, often requiring on-site cytopathology support. This multicenter prospective study evaluated whether directly placing...
