Background: The aim of this study is to evaluate the utility of image cytometry (ICM)-DNA analysis on cytological brush specimens in improving the sensitivity and diagnostic accuracy for biliary neoplasias.
Methods: A total of 71 patients with 89 samples of biliary tree brushing from a stenosis were included in this prospective study. Conventional cytology (CC) and DNA ploidy using ICM of the brushing were performed.
Background: To date, transgastric access in humans for natural orifice transluminal endoscopic surgery (NOTES) has been poorly evaluated.
Objective: To compare endoscopic visualization of the transgastric access point with the laparoscopically defined ideal entrance to the peritoneal cavity.
Design: Prospective pilot study in humans.
