Retrosternal pain subsequent to sclerotherapy.

J P Shoenut, A B Micflikier

    Gastrointestinal Endoscopy
    |April 1, 1986

    Summary

    Sclerotherapy for esophageal varices can cause temporary diffuse esophageal spasm. This condition involves prolonged, high-amplitude, and simultaneous contractions, leading to retrosternal pain.

    Area of Science:

    • Gastroenterology
    • Esophageal Motility Disorders

    Background:

    • Retrosternal pain is a potential complication after esophageal sclerotherapy.
    • Esophageal varices are often treated with sclerotherapy, especially after bleeding episodes.

    Purpose of the Study:

    • To investigate the cause of retrosternal pain following sclerotherapy.
    • To assess the immediate effects of sclerotherapy on esophageal motility.

    Main Methods:

    • A controlled trial involving seven patients undergoing sclerotherapy for esophageal varices.
    • Esophageal motility studies were performed before and shortly after sclerotherapy.
    • A control group of seven normal subjects underwent gastroscopy to evaluate its impact on esophageal motility.

    Main Results:

    • Sclerotherapy induced a transient pattern of diffuse esophageal spasm.
    • Key features included significantly prolonged wave duration (p < 0.05).
    • Increased peak amplitude and simultaneous contractions were also observed.

    Conclusions:

    • Sclerotherapy transiently induces diffuse esophageal spasm.
    • This spasm pattern likely explains the retrosternal pain experienced post-procedure.
    • Understanding these motility changes is crucial for managing post-sclerotherapy complications.
