Summary
Predicting the need for intraoperative endoscopy during laparoscopic resection of gastric subepithelial tumors is crucial. Tumor size and growth pattern are key factors indicating when a combined approach may be necessary.
Area of Science:
- Gastroenterology
- Surgical Oncology
- Minimally Invasive Surgery
Background:
- Laparoscopic resection is the standard treatment for gastric subepithelial tumors.
- Intraoperative endoscopy is sometimes required for lesion localization.
- Predictive factors for combined laparoscopic-endoscopic procedures are not well-defined.
Purpose of the Study:
- To identify factors predicting the need for intraoperative endoscopy during laparoscopic resection of gastric subepithelial tumors.
- To guide preoperative planning for combined surgical-endoscopic interventions.
Main Methods:
- Retrospective cohort study of patients undergoing laparoscopic gastric resection for subepithelial tumors (2005-2013).
- Analysis of a prospectively collected database.
- Evaluation of potential predictive factors for intraoperative endoscopy requirement.
Main Results:
- 38 patients underwent laparoscopic resection for gastric subepithelial tumors.
- 14 patients (36.8%) required intraoperative endoscopic assessment.
- Tumor growth pattern (P=0.002) and size (P=0.001) were significant predictors for needing intraoperative endoscopy.
Conclusions:
- Preoperative endoscopic ultrasound (EUS) assessment of tumor growth pattern and size is recommended.
- Small tumors (≤18 mm) with intraluminal growth may necessitate a combined endoscopic-assisted laparoscopic approach.
