BACKGROUND: Endoscopic submucosal dissection (ESD) is widely used for the treatment of gastric superficial neoplasms. Negative pathologic results after ESD can confuse the endoscopists and patients. The aim of this study was to evaluate the reasons for and the factors associated with negative pathologic results after ESD.
PATIENTS AND METHODS: From December 2008 to July 2015, a total of 1379 lesions diagnosed as definite dysplasia or adenocarcinoma by endoscopic forceps biopsy (EFB) were removed with an ESD procedure. The initial endoscopic and pathologic findings were analyzed.
RESULTS: The incidence of negative pathology after ESD was 2.0 % (28/1379). Compared with positive pathologic lesions, negative pathologic lesions were smaller and had less surface area (P < 0.001). The reasons for negative pathologic lesions after ESD were complete removal by EFB (n = 20), over-estimations of the EFB specimen (n = 5), and different ESD site (n = 3).
CONCLUSION: Small tumor size and surface area are associated with negative pathologic results after ESD. When negative pathologic results are reported after ESD, we should review the previous endoscopic biopsy tissue specimen and compare the previous EFB site to the ESD site. Thereafter, regular endoscopic examination of the lesion is needed.
