[Endoscopic mucosal resection and submucosal dissection of the gut neuroendocrine tumors]
Abstract:
Efficacy of miniinvasive endoscopic mucosal resection (EMR) and submucosal dissection (SD) of the gut neuroendocrine tumours (NET) was studied up. In the clinic in 2009-2013 yrs 5 patients were treated for NET. In 2 patients it was localized in stomach, in 1--in duodenal ampulla, in 1--in terminal portion of ileum (TPI), in 1--in rectum. All the patients were operated on, using endoscopic technologies: gastric tumours were excised using EMR with the help of a distal cap, duodenal and rectal tumours--using SD, and tumours of TPI--using EMR. Miniinvasive endoscopic excision of NET is an effective method of treatment.
Insights
Endoscopic mucosal resection (EMR) and submucosal dissection (SD) are effective treatments for gut neuroendocrine tumors (NET). These minimally invasive endoscopic techniques successfully removed NETs in five patients across various gastrointestinal locations.
Area of Science:
- Gastroenterology
- Surgical Oncology
- Endoscopic Surgery
Context:
- Neuroendocrine tumors (NETs) are a diverse group of neoplasms originating from neuroendocrine cells.
- Minimally invasive endoscopic techniques are increasingly utilized for gastrointestinal tumor resection.
- Evaluating the efficacy of endoscopic resection for specific NET locations is crucial for treatment planning.
Purpose:
- To assess the efficacy of endoscopic mucosal resection (EMR) and submucosal dissection (SD) for treating gastrointestinal neuroendocrine tumors (NETs).
- To evaluate the outcomes of miniinvasive endoscopic excision of NETs in a clinical setting.
Summary:
- A study reviewed five patients treated for NETs between 2009 and 2013.
- NETs were located in the stomach (2 patients), duodenal ampulla (1), terminal ileum (1), and rectum (1).
- Gastric tumors were resected using EMR with a distal cap; duodenal and rectal tumors via SD; and ileal tumors via EMR, demonstrating successful endoscopic removal.
Impact:
- Minimally invasive endoscopic excision, including EMR and SD, is confirmed as an effective treatment modality for gastrointestinal NETs.
- These endoscopic approaches offer a viable alternative to traditional surgery for selected NETs, potentially reducing patient morbidity.
- The findings support the expanded use of EMR and SD in managing NETs at various gastrointestinal sites.
