Endoscopic Treatment of Rectal Neuroendocrine Tumor(NET) Less Than 10mm

Cap Endoscopic Mucosal Resection(EMR-C) Versus Endoscopic Submucosal Dissection(ESD) for Treatment of Rectal Neuroendocrine Tumor(NET) Less Than 10mm

Cap-assisted endoscopic mucosal resection (EMR-C) and endoscopic submucosal dissection (ESD) have both been reported to be effective treatment methods for small rectal neuroendocrine tumor (NET) in limited studies. Which one is better has not been determined. We aimed to compare the efficacy and safety of EMR-C and ESD for the treatment of small rectal NET.

Inclusion Criteria:

• Age from 18 to 75 years;
• Definite diagnosis of rectal NET less than 10mm;
• Patients plan to receive either EMR-C or ESD treatment.

Exclusion Criteria:

• Serious comorbid diseases such as advanced malignant tumor and organ failure;
• Patients received conventional EMR, snare electrotomy and no treatment;
• Rectal NET with metastasis;
• Pregnant patient;
• Poor compliance
