h-APC_EMR Trial Summary

This trialtested a technique to reduce recurrence of colon adenomas after surgery. It found post-EMR ablation of resection margins using soft coagulation and h-APC reduced recurrence to 5%.

Who is the study for?
This trial is for patients needing removal of large, non-pedunculated colorectal polyps (≥20 mm) and who can provide consent. It's open to all ethnicities and races but excludes those with invasive carcinoma in the study polyp, prior partial EMR, certain lesion types, severe health issues (ASA class>3), pregnant or breastfeeding individuals, inflammatory bowel disease sufferers, emergency cases, coagulopathy or poor bowel preparation.Check my eligibility
What is being tested?
The trial tests Hybrid Argon Plasma Coagulation (h-APC) after Endoscopic Mucosal Resection (EMR) for colon adenomas. h-APC aims to reduce recurrence by lifting the mucosa with saline injection before ablation. This follows evidence that margin ablation post-EMR significantly lowers adenoma recurrence rates.See study design
What are the potential side effects?
While h-APC is designed to be safe with a low risk of side effects due to its cushioning technique during ablation, potential risks may include discomfort at the procedure site and rare complications like bleeding or perforation.

Treatment Details

Study Objectives

Outcome measures can provide a clearer picture of what you can expect from a treatment.
Primary outcome measures
Evaluate adenoma recurrence rate
Evaluate complete adenoma eradication rates
Secondary outcome measures
Completeness of thermal ablation of polyp resection margin
To evaluate the uniformity of the margins and bases of resection after hAPC ablation following an EMR.

h-APC_EMR Trial Design

1Treatment groups
Experimental Treatment
Group I: Group treatment h-APC and EMRExperimental Treatment1 Intervention
Standard endoscopic mucosal resection (EMR) technique will be used for primary removal of all polyps. Submucosal injection will be used to lift the polyp from the muscularis propria. Injection is used as per the current standard of care using a contrast agent and a lifting agent (e.g. NaCl 0.9% or Voluven). Snare electrocautery resection will be facilitated until complete visible removal of the complete polyp. Electrocautery snare technique is facilitated using standard microprocessor controlled electrocautery (e.g. ERBE VIO Endocut 3-1-6). Ablation of the margin after visibly complete removal of the polyp is routinely applied. For thermal ablation hybrid APC (Erbe Hybrid APC) will be applied using standard settings on the margin and resection base. Once resection and thermal ablation is considered complete the mucosal defect can be closed with clips or another preventative measure applied to reduce the risk for post-polypectomy bleeding.
