Cameron lesions are erosive-ulcerative alterations of gastric mucosa occurring in patients with large hiatal hernia, potentially causing gastrointestinal bleeding and iron deficiency anaemia.

Abstract

Cameron lesions are erosive-ulcerative alterations of gastric mucosa occurring in patients with large hiatal hernia, potentially causing gastrointestinal bleeding and iron deficiency anaemia. Diagnosis may be challenging, and not infrequently erosions are overlooked at endoscopy, so that repeated and unnecessary diagnostic procedures are performed, particularly in those patients with chronic anaemia. We described two peculiar cases of patients with iron deficiency anaemia in whom Cameron lesions were either overlooked or misinterpreted. By reviewing data of 22 publications reporting endoscopic and clinical data of 140 patients, we noted a large prevalence of females (75%). The most frequent presenting symptoms were anaemia (62%) and overt gastrointestinal bleeding (36%). Noteworthy, as many as 69% of patients underwent one or more previous upper endoscopy before diagnosis of Cameron lesion was achieved. Patients were mainly treated with proton pump inhibitor (PPI) therapy and iron supplementation. Moreover, endoscopic haemostasis was performed in 10% of case, blood transfusion was required in one third of cases, and a similar quote of patients underwent a surgical approach for hiatal hernia repair. The observation that as many as 60% patients were already receiving standard PPI therapy when diagnosis was performed would suggest that either long-term treatment with adequate dose PPI or surgical approach for hiatal hernia repair is required. In conclusion, Cameron lesion is still an overlooked diagnosis in patients with iron deficiency anaemia in whom a 5–9.2% prevalence has been reported.
