In this article, we have summarized the existing information regarding clinical presentation, diagnostic evaluation, and treatment options for this rare entity after presenting a case of GI-FL who was diagnosed during an EGD for evaluation of belching, heartburn, and weight loss.

Helicobacter pylori is a common worldwide bacterium, possessing adaptability that has created difficulty achieving eradication. While the standard treatment was thought to be triple therapy with a proton pump inhibitor, amoxicillin, and clarithromycin, growing rates of treatment failure and antibiotic resistance have stimulated research into novel regimens. Quadruple therapy with bismuth has been compared for both first- and second-line treatments, but eradication still has not reached expected goals. Innovative regimens including sequential and concomitant therapy, as well as the introduction of new antibiotics into previous treatment schedules, have shown promising improvements in eradication rates. We discuss and compare these unique regimens, reviewing the current literature to deduce those which are most likely to provide the highest success in curing H. pylori infection.
