Summary

The Overstitch (Apollo Endosurgery, Austin, Texas) is an FDA cleared product which attaches to a standard double channel endoscope. The Overstitch can place sutures under endoscopic guidance, with the goal of reproducing standard surgical techniques. These would include hemostasis, tissue approximation, anastomosis formation, fixation of intraluminal devices, or repair/closure of mucosal or full thickness defects such as perforations or endoscopic mucosal resection (EMR) sites. Knot tying of the endoscopically placed sutures is provided by an endoscopic cinching device that passes through the channel of the endoscope.

This feasibility trial will evaluate the ability of the Apollo suturing device (Overstitch) to endoscopically place sutures into normal mucosa, and then "tie" the sutures with the cinching device. These devices have been utilized effectively in explant, live porcine, and human cadaver colon and stomach models. In this treat and resect model, sutures would be placed in a segment of colon or stomach that is being surgically removed via open or laparoscopic technique for the treatment of benign or malignant disease. The sutures would be placed in a segment of normal mucosa remote to the pathology being surgically treated. In addition, the sutures will be placed under direct observation via laparoscopic or open visualization. After resection of the segment of colon, it will be evaluated grossly for level of suture placement, evidence of perforation, and quality of suture approximation with the cinching device.

Conditions

  • Colon Malignant Tumor
  • Colon Benign Tumor

Interventions

DEVICE

Overstitch Endoscopic Suturing System

Assess the safety and effectiveness of the Apollo endoscopic suturing device (Overstitch) and cinching device for placement of sutures and surgical knots in a segment of colon under laparoscopic or open visualization of the operative area. Patients will already require resection of segments of colon for treatment of benign or malignant disease and this will therefore be a treat and resect model
