Summary
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.
