Prophylactic injection of epinephrine-saline solution before endoscopic polypectomy significantly reduces the risk of postpolypectomy bleeding. This method is effective in preventing hemorrhage during gastrointestinal polyp removal.

Area of Science:

  • Gastroenterology
  • Endoscopic Surgery

Background:

  • Endoscopic polypectomy is a common treatment for gastrointestinal polyps.
  • Post-polypectomy hemorrhage is a significant complication, occurring in 0.3% to 6% of cases.
  • Prophylactic techniques are employed to mitigate bleeding risks.

Purpose of the Study:

  • To evaluate the efficacy of prophylactic adrenaline-saline solution injection in reducing post-polypectomy bleeding.
  • To assess the impact of submucosal epinephrine injection on hemorrhage rates during colonoscopic polypectomy.

Main Methods:

  • A randomized study involving 69 patients with colorectal polyps (>= 1 cm).
  • Patients were assigned to either submucosal epinephrine injection (group A) or no injection (group B).
  • Polypectomies were performed using conventional methods, with epinephrine injected into the polyp stalk/base in group A.

Main Results:

  • Nine episodes of post-polypectomy hemorrhage occurred: one in the epinephrine group (1/50) and eight in the control group (8/50).
  • A statistically significant reduction in bleeding was observed in the epinephrine group (p < 0.05).
  • Bleeding incidence correlated with polyp size and stalk diameter.

Conclusions:

  • Pre-procedure epinephrine injection is an effective method for preventing bleeding after colonoscopic polypectomy.
  • This technique offers a valuable strategy for reducing hemorrhage complications.
