AGA Clinical Practice Update on Nonampullary Duodenal Lesions: Expert Review:

This expert review provides a comprehensive framework for the clinical management of nonampullary duodenal polyps, which are often discovered incidentally during routine medical exams. The text outlines essential diagnostic protocols, emphasizing the need to distinguish between benign mimics and true adenomas while carefully mapping a lesion's location relative to the major papilla. Because these adenomas carry a risk of malignant transformation, the authors advocate for endoscopic resection as a safer, more cost-effective alternative to surgery, provided the patient’s overall health and longevity are considered. The guidelines detail specific resection techniques, such as cold or hot snare methods, while highlighting the necessity of managing significant procedural risks like delayed bleeding and perforation. Ultimately, the source establishes a standardized approach to post-resection surveillance and encourages further screening, such as colonoscopies, to address the high likelihood of concurrent intestinal issues.
