Laparoscopic management of pathologic gastroesophageal reflux after sleeve gastrectomy using the magnetic sphincter augmentation (MSA) device-a Video Vignette

Purpose The development of gastroesophageal reflux disease (GERD) has been shown to be not infrequent after laparoscopic sleeve gastrectomy (LSG). Management may vary from medical therapy to Roux-en-Y gastric bypass (RYGB) conversion. Magnetic sphincter augmentation (MSA) device has been shown to be a promising option with excellent results. The purpose of this video was to demonstrate the laparoscopic management of post-LSG GERD with MSA device implant. Materials and Methods An intraoperative video has been edited to demonstrate the MSA device placement after LSG for the treatment of pathologic GERD. Results The procedure started with the lysis of the perigastric adhesions to free the distal esophagus circumferentially. The posterior vagus nerve was identified, and a small window was created between the posterior esophageal wall anteriorly and the vagus nerve posteriorly. A hiatoplasty was performed using two non-resorbable interrupted 2.0 Prolene (R) sutures. The system's sizer was placed to measure the junctional circumference. A 15-mm MSA device was implanted. Conclusion MSA device placement seems technically feasible and safe with promising results in term of improved LES resting pressure and esophageal acid exposure. While future studies are necessary to corroborate these preliminary indications, MSA device may possibly become a valid option in surgeon armamentarium.

Automated summary

This study demonstrates the laparoscopic management of post-LSG GERD using MSA device, showing promising results in improving LES resting pressure and esophageal acid exposure.
