Abstract
AIM: Evaluate the diagnostic yield of biopsies obtained by EUS guidance in patients with gastric wall thickening and prior negative endoscopic biopsies.
MATERIAL AND METHODS: Data collected from October 2008 to January 2016 were analyzed in a retrospective manner. All included patients had undergone at least one endoscopy with a negative biopsy and showed evidence of gastric wall thickening by tomography, confirmed by endoscopy. All patients gave their written informed consent before the procedure. Demographics and baseline characteristics, including age, sex, number of previous endoscopies, and histopathological diagnosis were recorded. Follow-up data were obtained from a review of the electronic medical records. RESULT: In total, 22 patients with previous negative endoscopic biopsies and gastric wall thickening were included. Using EUSFNA/FNB, the diagnosis was made in the first procedure in 19/22 (86.30%) cases, while in 1/22 (4.5%) patients the diagnosis was made in the second EUS-FNA. A total of 18 (81.82%) patients with EUS-FNA were assessed using a standard Echo-tip, while the remaining four (18.18%) patients underwent EUS-FNB and using a ProCore needle. All patients with a final diagnosis of malignancy had a thickened gastric wall with impaired gastric distension and a loss of wall structure determined by EUS. Of patients with a benign final diagnosis, all (n=8) showed a thickened gastric wall by EUS but with preservation of the deep layers.
CONCLUSION: EUS-FNA/FNB is necessary in patients with a thickened gastric wall and prior negative biopsy on endoscopy. The procedure is safe and has a good diagnostic. © Acta Gastro-Enterologica Belgica.
