Summary
The novel full-thickness laparoendoscopic excision (FLEx) technique successfully removed stomach lesions in a pig model. This minimally invasive approach demonstrated technical sufficiency and safety for gastric lesion excision.
Area of Science:
- Surgical Innovation
- Minimally Invasive Surgery
- Gastrointestinal Endoscopy
Background:
- Initial validation of a novel full-thickness laparoendoscopic excision (FLEx) technique for gastric procedures.
- Focus on developing minimally invasive methods for stomach lesion removal.
Purpose of the Study:
- To validate the efficacy and safety of the FLEx technique in an animal model.
- To assess the technical feasibility of laparoendoscopic full-thickness gastric excision.
Main Methods:
- The FLEx technique was applied to seven 50-kg pigs.
- Involved laparoendoscopic brace bars, laparoscopic oversewing, and endoscopic excision.
- Animals were sacrificed immediately or 7-10 days post-procedure for evaluation.
Main Results:
- Uncomplicated full-thickness excision was achieved in all cases.
- Median procedure duration was 227 minutes; median specimen diameter was 5.5 cm.
- Autopsy confirmed technical sufficiency, with median site bursting pressure of 130 mm Hg.
Conclusions:
- The FLEx technique is a viable option for excising small, localized gastric lesions.
- Demonstrated safety and effectiveness in a preclinical animal study.
- Supports potential clinical application for gastric tumor resection.
