Incidence of retained biopsy specimens after esophagogastroduodenoscopy and colonoscopy

Toy Gregory et al.

In gastrointestinal endoscopy, biopsies must transit through the accessory channel and cap, presenting an opportunity for loss of tissue. We sought to determine the incidence of specimen retention in the accessory channel or cap and identify procedure characteristics associated with specimen retention.

Performance of endoscopic submucosal dissection for undifferentiated early gastric cancer: a multicenter retrospective cohort

Papaefthymiou Apostolis et al.

Undifferentiated early gastric cancer (UD-EGC) represents an extended indication for endoscopic submucosal dissection (ESD) based on the existing guidelines. This study evaluated the prevalence of UD-EGC recurrence after ESD, and potentially implicated risk factors.

Development, validation, and results of a national endoscopy safety attitudes questionnaire (Endo-SAQ)

Ravindran Srivathsan et al.

Safety attitudes are linked to patient outcomes. The Joint Advisory Group on Gastrointestinal Endoscopy (JAG) identifies the need to improve our understanding of safety culture in endoscopy. We describe the development and validation of the Endo-SAQ (endoscopy safety attitudes questionnaire) and the results of a national survey of staff attitudes.
