Summary
The new over-the-scope grasper (OTSG) effectively removes large foreign bodies, blood clots, and necrotic debris during endoscopy. This grasping tool offers a safe and efficient solution for challenging endoscopic procedures.
Area of Science:
- Gastroenterology
- Endoscopic Surgery
Background:
- Endoscopic removal of large foreign bodies, coagulated blood, or necrotic debris can be difficult due to limitations of current endoscopic instruments.
- There is a need for innovative devices to improve the efficiency and safety of these procedures.
Purpose of the Study:
- To evaluate the efficacy and safety of the over-the-scope grasper (OTSG) for endoscopic removal of challenging materials.
Main Methods:
- The OTSG, a novel grasping tool attachable to standard gastroscopes, was used in five patients.
- Indications included necrosectomy, bolus impaction, and removal of blood clots.
- Procedures involved necrosectomy through lumen-apposing metal stents and removal of esophageal obstructions.
Main Results:
- The OTSG was technically successful in all five patients.
- Procedures included endoscopic necrosectomy in two patients with severe pancreatitis.
- Other cases involved removal of esophageal blood clots and impacted food boluses.
- No procedure-associated complications were reported.
Conclusions:
- The OTSG is a valuable tool for the endoscopic removal of large particles, blood clots, and necrotic debris.
- Preliminary data suggest the OTSG is effective and user-friendly for complex endoscopic interventions.
