Core Tip
Core tip: Systematic literature review of giant gastric lipomas revealed 32 reported cases since 1980, with 2 new cases reported among 117110 esophagogastroduodenoscopies. Two authors independently reviewed literature, and decided by consensus which articles to incorporate. Average-patient-age = 54.5 ± 17.0 years (males = 68.8%). Mean-maximal-lipoma-diameter = 7.9 cm ± 4.1 cm. Lipoma locations: antrum-17, antrum and other gastric segments-7, other-8. Lipomas were submucosal-92%, subserosal-8%. Presentations included: acute upper gastrointestinal (UGI) bleeding-19, abdominal pain-5, nausea/vomiting-5, asymptomatic-3. Esophagogastroduodenoscopy was extremely helpful diagnostically; findings included: yellowish hue, well-demarcated margins, and smooth overlying mucosa. Endoscopic biopsies were infrequently diagnostic. Twenty of 21 abdominal CTs demonstrated characteristic lipoma findings: well-circumscribed, submucosal, and homogeneous mass with fat attenuation. Endoscopic-ultrasound showed characteristic findings in 80%. All patients underwent successful therapy without major complications/mortality, including: laparotomy-with-full-thickness-gastric-wall-resections-26; and other-6. Two newly reported patients presented with severe UGI bleeding from giant, ulcerated, gastric lipomas. This review may help standardize work-up of these patients.
