Abstract

Abstract : Goal: The aim of this study was to evaluate current practice in gastric ulcer follow-up to establish diagnostic yield and predictors of malignancy. Background: Repeat gastroscopy is routinely performed to confirm gastric ulcer healing and exclude malignancy. However, the incidence of malignancy at follow-up endoscopy is low, without consensus regarding case selection and timing. Study: New gastric ulcers diagnosed on gastroscopy at 2 institutions in Australia were identified through keyword search of endoscopy reports over a 5-year period (2013 to 2017). Data collected included patient demographics, clinical presentation, and endoscopic and histologic findings from initial and subsequent gastroscopies. Results: Of 795 patients, repeat gastroscopy was performed in 440 (55%). Malignancy was diagnosed in 52 (7%) with 83% identified at initial gastroscopy. Eight cancers were identified at repeat gastroscopy with malignancy yield of 2% (8/440). Three were diagnosed in patients with benign initial ulcer histology (3/286, 1%). One cancer was diagnosed during follow-up in a patient with benign histology but no repeat gastroscopy (1/286, 0.3%). Predictors of benign ulcers were absence of endoscopic suspicion [odds ratio (OR) 0.1 (0.03-0.13), P ≤0.005], complete healing on repeat gastroscopy [OR 0.5 (0.34-0.70), P =0.036] and benign initial histology [OR 0.12 (0.43-0.90), P ≤0.005]. Conclusions: Seven percent of new gastric ulcers were malignant with most identified with biopsy on initial gastroscopy. Malignancy yield from follow-up gastroscopy was 2%. Diagnostic yield of endoscopic follow-up may be low in ulcers with benign appearance and adequate histology. However, current practice of repeat gastroscopy is warranted in the absence of patient-based and lesion-based predictors of malignancy.
