We herein report two cases of portal venous gas (PVG) following alpha-glucosidase inhibitor (α-GI) therapy for diabetes mellitus. Anti-diabetic treatment with voglibose was commenced in the first case, while the second case was treated with miglitol. Both patients recovered without intensive treatment after discontinuing the α-GI therapy. α-GI medications may increase internal intestinal tract pressure by releasing carbon dioxide and hydrogen gas, potentially causing pneumatosis cystoides intestinalis (PCI) or PVG. Our experience suggests that α-GI therapy is an important potential cause of portal venous gas that can be treated conservatively.
