Systematic Review of Giant Gastric Lipomas Reported Since 1980 and Report of Two New Cases in a Review of 117110 Esophagogastroduodenoscopies
AIM: To systematically review the syndrome of giant gastric lipomas, report 2 new illustrative cases.
METHODS: Literature systematically reviewed using PubMed for publications since 1980 with following medical subject heading/keywords: ("giant lipoma") AND ("gastric") OR [("lipoma") and ("gastric") and ("bleeding")]. Two authors independently reviewed literature, and decided by consensus which articles to incorporate. Computerized review of pathology/endoscopy records at William Beaumont Hospitals, Royal Oak and Troy, Michigan, January 2005-December 2015, revealed 2 giant gastric lipomas among 117110 consecutive esophagogastroduodenoscopies (EGDs), which were thoroughly reviewed, including re-review of original endoscopic photographs, radiologic images, and pathologic slides.
RESULTS: Giant gastric lipomas are extremely rare: 32 cases reported since 1980, and 2 diagnosed among 117110 consecutive EGDs. Average patient age = 54.5 ± 17.0 years old (males = 22, females = 10). Maximal lipoma dimension averaged 7.9 cm ± 4.1 cm. Ulcerated mass occurred in 21 patients. Lipoma locations: antrum-17, body-and-antrum-4, antrum-intussuscepting-into-small-intestine-3, body-2, fundus-1, and unspecified-5. Intramural locations included submucosal-22, subserosal-2, and unspecified-8. Presentations included: acute upper gastrointestinal (UGI) bleeding-19, abdominal pain-5, nausea/vomiting-5, and asymptomatic-3. Symptoms among patients with UGI bleeding included: weakness/fatigue-6, abdominal pain-4, nausea/vomiting-4, early-satiety-3, dizziness-2, and other-1. Their hemoglobin on admission averaged 7.5 g/dL ± 2.8 g/dL. Patients with GI bleeding had significantly more frequently ulcers than other patients. EGD was extremely helpful diagnostically (
CONCLUSION: This systematic review may help standardize the endoscopic and radiologic evaluation and therapy of patients with this syndrome.
