How I do it: robotic hiatal hernia repair with stapled conversion from Nissen to Toupet fundoplication.

The purpose of this paper is to describe a robotic surgical technique for converting a slipped Nissen fundoplication to a Toupet fundoplication. Our technique utilizes four 8 mm robotic ports placed in a horizontal pattern above the umbilicus. The robotic tools we used are a vessel sealer, bipolar forceps, and Cadière forceps. In addition, an esophagogastroduodenoscopy (EGD) is placed through the esophagus into the stomach to be used as a bougie. If a hernia is present, we dissect it from the mediastinum until the posterior confluence is identified. Next sutures from the previous Nissen fundoplication are identified and removed to mobilize the crus. All adhesions around the stomach are removed to mobilize the esophagus, ensuing 3 cm of intraabdominal esophagus is available. Using an EGD as a bougie, we used two interrupted, 0 silk suture over Teflon pledgets placed in a horizontal mattress fashion to close the hiatal defect. Using an endoscope, we identified the previous Nissen fundoplication and used a 60 mm blue load stapler to transect the wrap from the stomach. The 360° Nissen fundoplication had now been converted into a 270° Toupet fundoplication, which is confirmed with the EGD. The functionality of the wrap is confirmed if the "Stack of Coins" sign is present, and the wrap lies tight against the scope. A Nissen-to-Toupet fundoplication conversion using a robotic-assisted surgical technique may be useful in reducing reoperations and complications in patients undergoing fundoplication surgery.
