The demand for endoscopic retrograde cholangiopancreatography (EUS) in the United States is projected to exceed current resources. This study estimates a significant need for EUS procedures annually, highlighting potential capacity shortfalls.

Area of Science:

  • Gastroenterology
  • Medical Technology Assessment
  • Health Services Research

Background:

  • Endoscopic ultrasound (EUS) is a standard diagnostic and staging tool for gastrointestinal (GI) malignancies.
  • Uncertainty exists regarding the sufficiency of current EUS resources to meet potential demand.
  • This study evaluates the hypothetical demand for EUS services in the U.S.

Purpose of the Study:

  • To estimate the total number of EUS procedures that would be indicated annually in the United States.
  • To assess whether existing EUS resources can meet this projected demand.
  • To identify factors for future EUS capacity planning.

Main Methods:

  • Retrospective review of EUS cases from 3 expert centers in 1997.
  • Extrapolation of trends to national cancer statistics.

  • Calculation of hypothetical demand based on GI malignancy incidence, unresectable cases, elderly nonsurgical candidates, and emerging indications.

    • Main Results:

    • A hypothetical annual demand of 79,568 EUS cases was calculated for the U.S.
    • Specific indications include esophagus (10,287), stomach (10,666), pancreas (23,069), and rectal (35,546).
    • Including "other" indications, the potential annual procedures could reach 89,116, with a conservative estimate of 79,572.

    Conclusions:

    • Current EUS resources in the U.S. are likely insufficient to meet the projected demand.
    • Future planning must consider the number and capacity of endoscopy units performing EUS.
    • Implications for EUS training programs in the United States require careful consideration.
