@entity850 after endoscopic submucosal dissection for early XXXX and adenomas.

@entity1 @entity384 @entity418 @entity850 @entity356
BACKGROUND AND AIM:    @entity850 is a complication that may occur after endoscopic submucosal dissection (ESD) of @entity356 . The goal of the present study was to investigate the incidence, risk factors and management of @entity356 after ESD. METHODS: The medical records of 308 @entity1 who underwent ESD for @entity356 were reviewed. @entity850 is defined as having symptoms caused by an obstruction through which a 1-cm diameter endoscopic fiber cannot be passed. RESULTS: @entity850 was identified in six of 308 @entity1 (1.9%). Three of the six lesions were located in the prepylorus, two cases in the antrum and one in the @entity418 . The mean longitudinal distance and the mean area of the resected specimens in the six cases with stricture (7.8    2.0 cm, 34.0    15.8cm(2) , respectively) was significantly larger than in those without stricture (4.5    1.4cm, 12.7    8.3cm(2) , respectively, P<0.01). The ratio of the resected circumference/whole circumference was 83.3  7.5% in those with stricture in comparison to 25.4    16.3% in those without stricture (P<0.01). All six @entity1 underwent @entity384 , and obtained relief from stricture. However, one @entity1 experienced a @entity356 and recovered following conservative therapy. CONCLUSION:    Sub-circumferential resection over 75% of the circumference by ESD in the prepylorus, antrum and @entity418 is a risk factor for the occurrence of stricture. Early intervention might be considered for this high-risk group to avoid a perforation during balloon dilation.
