Multisite study of Titan SGS stapler in longitudinal gastric resection

Abstract

Background Standardization of the laparoscopic sleeve gastrectomy procedure is needed to improve patient outcomes. A single-fire 23 cm stapler was developed to streamline the operation. Comparative testing conducted on excised human tissue has demonstrated the superiority of the novel Titan SGS stapler to two commonly utilized commercial devices in both staple line integrity and burst pressure. We hypothesized that the stapler would be safe and effective in creating longitudinal gastric resections in human patients. Methods 61 patients were enrolled to undergo gastric resection with the Titan SGS stapler. Perioperative interventions and post-operative adverse events were recorded. Upper GI study was completed on post-operative day 1, and patients were followed for 6 weeks post-operatively to determine any subacute device-related adverse events. Results Surgeon feedback for intraoperative device utilization and post-operative gastric pouch shape were positive. Adverse events were found to be mild, limited, and generally well-known effects of bariatric surgery. One episode of post-operative hemorrhage required surgical takeback, with no criminal bleeding vessel identified. Conclusion The Titan SGS stapler is both safe and effective in sleeve gastrectomy pouch creation.
