Endoscopic submucosal dissection with deliberate muscularis propria exposure for curative resection of a large type 1 gastric neuroendocrine tumor: a case report
To demonstrate that curative organ-preserving resection using advanced endoscopic techniques is a viable option for selected cases of large type 1 gastric neuroendocrine tumors (gNETs).
Approach:
Surgical Technique: Endoscopic submucosal dissection with deliberate muscularis propria exposure (ESD-MPE) was used for the junctional tumor due to its size and location, while conventional ESD was used for the gastric body lesion.
Key Findings:
Both lesions were confirmed as pT1b, G2 NETs with negative margins.
ESD-MPE is an effective minimally invasive treatment option for larger type I gNETs without metastasis.
Interpretation:
The case illustrates that with careful patient selection and advanced endoscopic techniques, curative treatment for larger type I gNETs is achievable.
Limitations:
The study is based on a single case report, limiting generalizability.
Long-term outcomes of ESD-MPE for larger type I gNETs are not discussed.
Conclusion:
ESD-MPE represents a minimally invasive approach for selected cases of large type I gNETs.
