Submucosal epinephrine injection before gastrointestinal polyp removal significantly reduced immediate bleeding. This endoscopic technique helps prevent post-polypectomy hemorrhage and perforation.

Area of Science:

  • Gastroenterology
  • Endoscopic Procedures
  • Surgical Complication Prevention

Background:

  • Gastrointestinal polyps necessitate removal due to risks of bleeding, obstruction, and malignancy.
  • Polypectomy, while standard, carries potential complications like hemorrhage and perforation.
  • Preventive measures are crucial to enhance the safety of endoscopic polyp removal.

Purpose of the Study:

  • To evaluate the efficacy of submucosal epinephrine injection prior to polypectomy.
  • To determine if this intervention reduces the incidence of post-polypectomy bleeding and perforation.

Main Methods:

  • A randomized controlled trial involving 120 patients with sessile gastrointestinal polyps.
  • Patients were assigned to either submucosal epinephrine injection before polypectomy or a control group without injection.

  • Complications, particularly bleeding and perforation, were monitored for one month post-procedure.

    • Main Results:

    • A total of 151 polyps were analyzed across 120 patients.
    • The epinephrine group showed a trend towards reduced overall post-polypectomy hemorrhage (2/75 vs. 7/76, P=0.07).
    • Immediate post-polypectomy hemorrhage was significantly lower in the epinephrine group (1/75 vs. 7/76, P=0.03), while perforation rates were similar (1 per group).

    Conclusions:

    • Submucosal epinephrine injection is an effective method for preventing immediate bleeding after gastrointestinal polypectomy.
    • The technique offers a valuable strategy to mitigate a common complication of polyp removal.
