Structured oropharynx, hypopharynx and larynx assessment during routine esophagogastroduodenoscopy improves detection of pre- and early cancerous lesions: a multicenter, comparative study.

A structured assessment of the oropharynx, hypopharynx and larynx (OHL) may improve the diagnostic yield for the detection of precancerous and early cancerous lesions (PECLs) during routine esophagogastroduodenoscopy (EGD). Thus, we aimed to compare routine EGDs ± structured OHL assessment (SOHLA), including photo documentation with regard to the detection of PECLs. Consecutive patients with elective EGD were arbitrarily allocated to endoscopy lists with or without SOHLA.
