Rectal varices can cause lower digestive tract bleeding. Advanced rectal varices and a positive "red color" sign indicate a higher risk of hemorrhage in patients with portal hypertension.

Area of Science:

  • Gastroenterology
  • Hepatology
  • Endoscopy

Background:

  • Rectal varices are a significant cause of lower digestive tract bleeding in patients with portal hypertension.
  • The etiology, pathology, and optimal treatment for rectal varices remain incompletely understood.
  • Identifying characteristics of hemorrhage-prone rectal varices is crucial for patient management.

Purpose of the Study:

  • To evaluate rectal varices in patients with portal hypertension.
  • To identify common characteristics of rectal varices associated with hemorrhage.
  • To determine risk factors for bleeding from rectal varices.

Main Methods:

  • Retrospective analysis of 40 patients with rectal varices among 425 patients with portal hypertension.
  • Examination of underlying hepatic diseases, hepatic function, and endoscopic findings.

  • Correlation of endoscopic features with hemorrhage incidence.

    • Main Results:

    • Hemorrhage from rectal varices occurred in 15 of 40 patients.
    • Hemorrhage prevalence increased with advanced rectal variceal form (p<0.05).
    • A positive "red color" sign was significantly associated with increased hemorrhage prevalence (p<0.05).

    Conclusions:

    • Advanced rectal variceal form and a positive "red color" sign are significant predictors of hemorrhage.
    • These findings aid in stratifying bleeding risk in patients with rectal varices.
    • Further research into treatment strategies for rectal varices is warranted.
