Contributor(s): Kyle Mathews

Introduction

  • Dissection of pyloric musculature to improve gastric outflow.

Uses

Advantages

  • Simple.
  • No penetration of mucosa (stomach lumen).

Disadvantages

  • Unable to biopsy mucosa or examine lumen (important for diagnosis confirmation).
  • Evidence that myotomy heals quickly - recurrence possible.
  • Minimal effect on gastric emptying time.
    NOT recommended for gastric outflow disease unless there is no mucosa involvement and the owner has been informed about possible recurrence.
