Background and study aims: This study aimed to determine whether the use of i-scan endoscopy provides additional benefits to conventional endoscopy in the diagnosis of gastric precancerous lesions. Patients and methods: A total of 120 patients with histologically-verified intestinal metaplasia (IM) or atrophic gastritis (AG) were prospectively evaluated by esophagogastroduodenoscopy. Endoscopic exam-inations were performed using i-scan and high-definition white-light endoscopy (HD-WLE). The diagnos-tic yields of both techniques and the number of targeted biopsies per patient were compared. Results: A total of 318 suspicious lesions were detected in 108 patients with i-scan (n = 186) and 81 patients with HD-WLE (n = 132). The diagnostic yields of i-scan and HD-WLE were 81.6% (98/120) versus 77.5% (93/120), respectively (p > 0.05). When only targeted biopsies were taken into account, the diag-nostic yields of i-scan and HD-WLE were 89.8% versus 65.4%, respectively (p < 0.05). The mean number of biopsies per patient for i-scan and HD-WLE were 3.27 (393/120) and 7.3 (882/120), respectively (p < 0.05). The mean endoscopic procedure times were 16 and 17 min for i-scan and HD-WLE, respec-tively (p > 0.05). Conclusions: Although targeted biopsies with i-scan were not found to be significantly superior to either targeted or random biopsies with HD-WLE, the number of biopsies required to confirm these lesions was much lower.
