Abstract:
Background/Aims:Accurately diagnosing diffuse gastric wall thickening is challenging. Hypertrophic gastritis (HG), while benign, mimics the morphology of Borrmann type 4 advanced gastric cancer (AGC B-4). We compared the features of endoscopy and endoscopic ultrasonography (EUS) between them.
Methods:We retrospectively reviewed patients who underwent EUS for gastric wall thickening between 2000 and 2021, selecting HG and pathologically confirmed advanced gastric cancer cases. Ulceration and antral wall thickening were determined via endoscopy, while EUS assessed the 5-layered gastric wall structure, measuring the proper muscle (PM) layer and total wall thickness.
Results:Male dominance was observed in AGC B-4, and the hemoglobin and albumin levels were significantly lower. The rate of antral wall thickening and presence of ulceration were significantly higher in AGC B-4 cases. Destruction of the PM layers was observed only in AGC B-4 cases, and the PM was significantly thicker in AGC B-4 cases. Forceps biopsy had an excellent success rate in ulcer-present AGC B-4 cases, but only a 42.6% success rate was observed for cases without ulcers, necessitating additional diagnostic modalities. A PM thickness of 2.39 mm distinguished between AGC B-4 and HG effectively. The multivariable analysis showed that a thickened PM layer and the presence of ulceration were significant risk factors for the diagnosis of AGC B-4.
Conclusions:Endoscopic findings of a thickened gastric wall, including antral involvement, and presence of ulcer were significant risk factors for the diagnosis of AGC B-4. EUS findings of destroyed wall layers and a thickened PM of >2.39 mm were the key points of differentiation between HG and AGC B-4.
