Endoscopic ultrasound guided gastrojejunostomy

Area of Science:

• Gastroenterology
• Interventional Endoscopy
• Surgical Innovation

Background:

• Gastric outlet obstruction (GOO) and afferent loop syndrome are challenging conditions often requiring invasive interventions.
• Current treatments for GOO, such as enteral stenting and balloon dilation, face limitations including recurrence and patency issues.
• Surgical interventions for these conditions carry significant risks and potential adverse events.

Purpose of the Study:

• To evaluate the efficacy and safety of endoscopic ultrasound-guided gastrojejunostomy (EUS-GJ) in treating benign and malignant GOO and afferent loop syndrome.
• To compare EUS-GJ with existing treatment modalities for GOO.
• To highlight EUS-GJ as a less invasive alternative to surgery.

Main Methods:

• EUS-GJ involves creating a gastrojejunal bypass using a lumen-apposing metal stent (LAMS) via a newly formed fistulous tract.
• Techniques for EUS-GJ vary, with no single method yet established as superior.
• Data from limited studies on afferent loop syndrome and malignant GOO were analyzed.

Main Results:

• Initial data for afferent loop syndrome indicate high technical and clinical success rates with reduced reintervention.
• For malignant GOO, EUS-GJ demonstrated superiority over standard enteral stenting by decreasing recurrence and reintervention.
• EUS-GJ provides a potential solution for long-term patency in benign GOO, overcoming limitations of prior endoscopic treatments.

Conclusions:

• EUS-GJ is an effective and less invasive endoscopic approach for managing GOO and afferent loop syndrome.
• It offers advantages over traditional enteral stenting and balloon dilation, particularly in terms of recurrence and patency.
• EUS-GJ presents a viable alternative to surgery, potentially reducing patient morbidity.
