Endoscopic resection of a duodenal neuroendocrine tumor using padlock (Over-The-Scope clip): case report in a tertiary care hospital

Abstract

Introduction: With the evolution of endoscopic techniques and the performance of increasingly invasive procedures, the appearance of full-thickness endoscopic resection profile the diagnosis and definitive treatment of injuries involving any layer of the gastrointestinal tract. The Padlock is a new device in the clip-on-scope (OTSCs) category, which has recently been qualified in clinical practice. The purpose of this study is to report our experience and document the effectiveness of Padlock for performing endoscopic resection of duodenal lesions. Case summary: Male, 69 years old, with abdominal pain. Upper digestive endoscopy revealed a 12 mm neuroendocrine tumor in the duodenum. The lesion was removed by endoscopic full-thickness resection with the aid of the Padlock and the anatomopathological examination showed free margins. Literature review conducted with discussion on the feasibility, efficacy and safety of this procedure. Conclusion: Endoscopic full-thickness resection of duodenal carcinoid using a padlock appears to be a viable and effective procedure. However, the most prospective and randomized studies are provided for comparisons related to the techniques used conventionally and to establish a clinical safety of this new technique
