title: Yield of routine endoscopy beyond the duodenal bulb.
abstract: The authors determined the clinical yield, endoscopic time, and patient tolerance of routine upper endoscopy beyond the duodenal bulb. From May through October 1994, all patients undergoing routine esophagogastroduodenoscopy (EGD) were recruited for study. Each procedure was timed from start to finish by the endoscopy nurse, and, in addition, the time of the postbulbar examination was recorded. The endoscopy nurse assessed the patient's comfort level when the endoscope was advanced into the duodenal bulb and again at the postbulbar region. A total of 250 EGDs were performed. There were 152 males and 98 females, with a mean age of 57.1 (range, 23-91) years. Indications for the procedure were as follows: gastroesophageal reflux disease symptoms 82, epigastric pain 64, dysphagia 46, Barrett's surveillance 25, anemia 23, other research study 16, and other 61. The mean time for the procedure was 11 min and 54 s, whereas the mean time for the postbulbar examination was 46.6 s. Patients tolerated endoscope insertion well both before and during examination of the postbulbar duodenum. The only postbulbar finding that affected clinical management was a postbulbar ulcer in a patient without other ulcers who was positive for Helicobacter pylori. Although routine endoscopic examination beyond the duodenal bulb involves minimal time and is well tolerated by patients, the yield of pathologic findings is low (3.6%) and the yield of findings that alter clinical management even lower (0.4%). In patients without prior GI surgery undergoing routine EGD for indications other than suspected small bowel pathology or active upper GI bleeding, examination of the postbulbar duodenum can be considered an elective part of the procedure.
