Summary
A new scoring system aids decisions on suturing after endoscopic resection of duodenal submucosal tumors (SMTs). This tool helps reduce complications like bleeding and perforation by guiding when to use purse-string sutures for duodenal SMTs.
Area of Science:
- Gastroenterology
- Surgical Oncology
- Medical Device Development
Background:
- Endoscopic resection (ER) is used for duodenal submucosal tumors (SMTs).
- ER of duodenal SMTs carries risks of bleeding and perforation.
- Effective suturing is vital to minimize these complications.
Purpose of the Study:
- To develop a clinical scoring model.
- To aid in suture decision-making for duodenal SMTs treated with ER.
Main Methods:
- 137 patients with duodenal SMTs undergoing ER were included.
- Patients were divided into training (95) and validation (42) cohorts.
- Multivariate logistic regression was used to create and validate the scoring system.
Main Results:
- The scoring system includes extraluminal growth (2 points) and full-thickness resection (3 points).
- The model showed high predictive accuracy (AUC 0.900).
- Suturing probability increased significantly with higher scores in both cohorts.
Conclusions:
- A novel scoring system can assist clinicians.
- It facilitates decisions on suturing techniques for duodenal SMTs.
- This tool aims to improve patient outcomes by reducing ER complications.
