Minimally Invasive Full-Thickness Resection of a Non-Lifting Adenoma in an Ulcerative Colitis Patient Using OVESCO: A Case Report.

INTRODUCTION

Patients with longstanding ulcerative colitis (UC) face an increased risk of colorectal cancer, necessitating regular surveillance. Chronic inflammation frequently leads to submucosal fibrosis, making the resection of non-lifting lesions difficult with standard techniques like endoscopic mucosal resection (EMR) or endoscopic submucosal dissection (ESD).

CASE PRESENTATION: We present a 76-year-old UC patient with a splenic flexure adenoma that was unresectable via EMR/ESD. Given the high surgical risk, the OVESCO system was used, achieving clear margins and avoiding colectomy.

CONCLUSION

This case highlights full-thickness resection devices as a minimally invasive alternative for challenging polyps in UC, preserving bowel function while avoiding major surgery or stoma formation.
