Concept: Gastrointestinal Endoscopy (GIE) Procedures

 Printer friendly

Concept Description

Last Updated: 2022-08-15


    Gastrointestinal endoscopy (GIE) procedures are used to investigate the symptoms and signs of gastrointestinal (GI) diseases and responses to treatment. They are also used to aid in the prevention of certain cancers, such as colorectal cancer (CRC) and esophageal cancer. GIE procedures are used to examine both the lower and upper parts of the GI system.

    Colonoscopy and sigmoidoscopy are procedures for the lower part of the GI system, while gastroscopy, esophagoscopy and small bowel endoscopy are procedures for the upper part of the GI system. Small bowel endoscopy is a newer procedure (not identified in the medical services data until 2001); other procedures have been in use for much longer periods.

Tariff Codes for GIE and Small Bowel Endoscopy Procedures

    There are several tariff codes available in the Medical Services data that were used to identify lower and upper GIE and small bowel endoscopy procedures in Lix et al. . They investigated GIE procedure rates for the adult (age 19+) population of Manitoba from fiscal years 1984/85 to 2016/17.

    NOTE: A list of these codes can be found on-line in Appendix 3: Appendix Table 3.2 Tariff Codes Used to Identify Study Cohorts of the deliverable.
