OBJECTIVES: No protocol for esophagogastroduodenoscopic examination of the duodenum has been established. We examined the feasibility and ability to detect neoplasms of a novel duodenal examination protocol.
METHODS: This was a two-facility, prospective, observational study. Our protocol, the Seven Pictures Rule (7PR), requires pictures of the following seven locations: anterior and posterior to the bulb, area of and contralateral to the superior duodenal angle, area of and contralateral to the ampulla, and the transverse duodenum. The primary outcome was rate of completion of 7PR. Secondary outcomes were overall rates of detecting neoplasms, rates of detecting neoplasms for each location, examination time, and completion rates for standard or ultrathin endoscopes.
RESULTS: There were 1549 participants. The 7PR completion rate was 81.1% and the detection rates of overall neoplasms, adenomas, and carcinomas were 0.84%, 0.71%, and 0.06%, respectively. The area in which most neoplasms was detected was contralateral to the ampulla (69.2%), and the fewest the transverse duodenum (0%). Mean duration of duodenal examination was 53.1 s. Completion rates for standard vs. ultrathin were 84.4% (1077/1276) vs. 65.6% (179/273) (P < 0.01), respectively.
CONCLUSIONS: Seven Pictures Rule is acceptable for duodenal examination and a potential quality indicator.
