Summary
Submucosal tunneling endoscopic resection (STER) and endoscopic submucosal dissection (ESD) are effective for esophageal tumors. STER offers a significantly shorter hospital stay compared to ESD.
Area of Science:
- Gastroenterology
- Endoscopic Surgery
- Oncology
Background:
- Submucosal tunneling endoscopic resection (STER) is a novel endoscopic technique.
- Esophageal submucosal tumors (SMTs) require effective treatment options.
- Comparing STER with endoscopic submucosal dissection (ESD) is crucial for clinical practice.
Purpose of the Study:
- To compare the efficacy and safety of STER versus ESD for esophageal SMTs.
- To evaluate key outcomes including complete resection, operation time, and complications.
- To determine the optimal endoscopic approach for SMT management.
Main Methods:
- A systematic literature search was performed in major databases (PubMed, Embase, Cochrane Library).
- Six comparative studies were included in this meta-analysis.
- Primary outcomes: complete resection (CR) rate, en bloc resection (ER) rate, length of hospital stay (LOS), operation time. Secondary outcomes: complication rates, tumor recurrence.
Main Results:
- No significant differences were found between STER and ESD in CR rate, ER rate, or operation time.
- STER demonstrated a significantly shorter length of hospital stay (LOS) compared to ESD.
- Both techniques showed low rates of complications and tumor recurrence, with no detected publication bias.
Conclusions:
- Both STER and ESD are safe and effective for resecting esophageal SMTs.
- STER offers a significant advantage with a reduced hospital stay.
- These findings support STER as a favorable option for managing esophageal SMTs.
