ReviewManagement of foreign bodies of the upper gastrointestinal tract: update.
Management of 242 foreign bodies of the upper gastrointestinal tract are reported. Thirty-nine were in the pharynx, 181 in the esophagus, 19 in the stomach, and 3 in the small bowel. The flexible panendoscope was used 211 times (87.2%) to manage these foreign bodies, while the rigid esophagoscope was used 12 times (5.0%). ⋯ Button batteries lodged in the esophagus represent an emergency and should be removed without delay. Once in the stomach, they will usually pass through the gastrointestinal tract without difficulty. The forward-viewing flexible panendoscope has become the instrument of choice in managing foreign bodies in most tertiary medical centers as well as in the community hospitals.

Randomized Controlled Trial Clinical TrialSelective sedation for colonoscopy.
A study of selective sedation for colonoscopy was conducted in two parts. All procedures were performed by one experienced colonoscopist. In the first phase, 41 patients received intravenous sedation before colonoscopy and were then prospectively randomized to either a "not-reversed" group, which did not receive flumazenil before withdrawal of the colonoscope, or to a "reversed" group, which received flumazenil before colonoscope withdrawal. ⋯ Twenty-three percent required intravenous sedation, whereas 78% did not receive any sedation. Ninety-three percent were willing to undergo another colonoscopy without prior sedation. Only 8% preferred prior intravenous sedation before any future colonoscopy.
