Interventional embolization effectively treated gastrointestinal hemorrhage (GI) in 83% of patients. Minicoils reduced serious complications compared to fluid agents, offering a safer option for bleeding control.

Area of Science:

  • Interventional Radiology
  • Gastroenterology
  • Vascular Surgery

Background:

  • Gastrointestinal hemorrhage (GI) poses significant clinical challenges.
  • Endoscopic and surgical interventions have limitations for severe or recurrent bleeding.

Purpose of the Study:

  • To evaluate the long-term efficacy and safety of interventional embolization for gastrointestinal hemorrhage.
  • To assess the impact of different embolic agents on outcomes.

Main Methods:

  • Retrospective analysis of 35 patients with GI bleeding treated via radiological intervention from 1989 to 1997.
  • Embolization utilized agents like Ethibloc, metal coils, and polyvinyl alcohol particles.
  • Diverse bleeding sources included ulcers, diverticula, malignancy, and vascular malformations.

Main Results:

  • Complete hemostasis was achieved in 83% of patients (29/35).
  • Partial success with persistent bleeding occurred in 14% of cases.
  • A complication rate of 14% was observed, with initial fatalities from intestinal ischemia, later reduced by minicoils.

Conclusions:

  • Minimally invasive interventional embolization is a highly effective treatment for gastrointestinal hemorrhage.
  • The shift towards minicoils has significantly decreased the risk of severe complications.
