Introduction: Endoscopic treatments have become vital in managing transmural gastrointestinal defects both as a first-line and rescue treatment. The latest advances in interventional endoscopy have made a paradigm shift in managing these defects from surgery to minimally invasive endoscopic procedures. We present a unique presentation of a perforation caused by foreign body ingestion (FBI), leading to a chronic duodenal fistula that was treated with a novel through the scope suturing device (X-Tack Endoscopic HeliX Tacking System).

Case Description/Methods: A 28-year-old male presented with a 4-week history of intermittent right upper quadrant abdominal pain associated with high-grade fevers. He had a past medical history and multiple episodes of FBI in the past.CT scan of the abdomen and pelvis revealed a large (14.2cm X 10.7cm) multiloculated liver abscess(Figure A). It also showed an impacted foreign body in the duodenum (Figure B) and multiple foreign bodies in the small intestine (Figure C). An EGD was performed, which revealed a spork in the second part of the duodenum (Figure D), which was removed using a snare(Figure E). A chronic-appearing fistulous tract was visualized at the duodenal sweep(Figure F). We decided to close the defect with a novel through-the-scope suturing device. Four HeliX Tacks were placed approximating the defect, and the suture was cinched with the endoscope cinching device. After deployment of the sutures, there appeared to be a residual opening; a second X-Tack with four HeliX Tacks was placed, but unfortunately, the suture broke. Finally, the third set of Helix Tack was placed, approximating the residual defect. After deployment, the fistulous tract appeared to be closed (Figure G). A follow-up CT scan with contrast revealed no residual duodenal leakage, and the patient improved clinically.

Discussion: Our case exhibits a rare presentation of chronic contained duodenal perforation successfully treated with the help of a through-the-scope suturing device. This novel technique has several advantages over the traditional through-the-scope (TTS) and over-the-scope clips (OTS). It allows a suture-based deep submucosal/intramuscular fixation through a standard scope. This technique is superior for the closure of large mucosal defects as compared to traditional TTS clips. In addition, this device has improved accuracy and simplicity without the need for endoscope withdrawal for device loading. It is less invasive than surgery and more appropriate for clinically stable patients.
