Reoperative Hiatal Hernia Repair

Over the past century, improvements in the understanding and diagnosis of foregut disorders have led to the evolution of better procedures and surgical approaches. This innovation brings new challenges related to complications and reoperation for the foregut surgeon. Surgical reinterventions are particularly challenging from a technical perspective due to multiple factors, including dense adhesions, scarring, obliteration of tissue planes, and altered anatomy1,2,3,4,5. These redo foregut surgeries&#160;have increased morbidity in patients with higher incidences of esophageal perforation, delayed gastric emptying, and vagal nerve injury1,6,7,8. Mesh repairs at the hiatus complicate reintervention further, having higher rates of major resection requiring complex reconstruction9,10. The advent of advanced endoscopic therapies creates ever-evolving challenges for foregut surgeons when dealing with their associated complications or failures11,12,13. Furthermore, redo foregut operations are associated with worsening success rates and patient satisfaction with successive reoperations compared with primary intervention14,15,16,17. This highlights the importance of patient selection and accurate diagnosis prior to redo surgery for optimal outcomes.
While traditionally performed using an open approach, laparoscopic approaches to redo foregut surgery are safe and efficacious14,18. However, due to the greater difficulty associated with altered anatomy and adhesions, conversion to open surgery is still a possibility. With the emergence of robot-assisted surgery in urology and gynecologic surgery19,20, the superior visualization and dexterity compared to laparoscopy would appear to likely have some benefit in redo foregut surgery as well. Indeed, emerging research has shown safety and improved outcomes, including less conversions to open surgery and decreased hospital stays compared with the laparoscopic approach for redo foregut surgery21,22,23.
Although it is ultimately up to the foregut surgeon to determine the safest procedure, this article aims to demonstrate the approach and technical considerations for redo foregut surgery to provide a &#34;framework&#34; when confronted with this challenge. While a robotic-assisted approach is described, the principles described could be similarly applied to laparoscopy.

Technical Considerations and Approach to Redo Foregut Surgery

Our research focuses on thoracic surgery with specific regard to reoperative foregut operations. A large portion is surgical outcomes-based research, but we also emphasize quality improvement in surgery, such as with this protocol. In this video, we discuss our approach to reoperative foregut surgery.In foregut surgery, technological advances continue to be made in the intraop and pre-op settings. Improvements in diagnostic technology, such as with the Endoflip system and high resolution manometry provide more accurate information in diagnoses of the foregut, while robotic technology and intraop monitoring help us provide the best care possible in surgery. Most literature, looking at reoperative foregut surgery emphasizes the outcomes but not necessarily the approach to performing the operation.We describe a step-by-step approach to the operation, while maintaining the general principles broadly, and thus, providing a reference for other foregut surgeons. In the future, we will continue to focus on reviewing outcomes of other reoperative foregut surgeries with the goal of developing guidelines and standardizing the management of these cases.

Robotic Reoperative Hiatal Hernia Repair After Post-Laparoscopic Procedure

To begin, position the anesthetized patient supine with arms out and a footboard to facilitate steep reverse Trendelenberg positioning. Using the open hasson technique, enter the peritoneal cavity in the left supra umbilical space to insert the camera port. Next, insert one eight millimeter port in the right upper quadrant, 10 centimeters above the umbilicus, and one port in the left upper quadrant.Place the assistant port in the right lower quadrant. Insert the liver retractor through a five millimeter port, placed in the extreme lateral part of the right upper quadrant. Then dock the surgical robot.To reduce hiatal hernia, begin by removing the adhesions of the bowel to the abdominal wall. Then, using a robotic bipolar surgical energy device, open the gastrohepatic ligament. Open the lesser sac by removing adhesions and additional short gastric artery branches.Using a combination of blunt and electrocautery dissection with the robot, dissect the hernia sac, circumferentially at the hiatus. Then use laparoscopic scissors to carefully dissect the dense adhesions between the liver and stomach. To note previous fundoplication, perform sharp dissection with laparoscopic scissors and undo the wrap to completely free the stomach.Next, using the combination of blunt and sharp dissection, mobilize the esophagus, transhiatally in the mediastinum. Under endoscopy, identify the gastroesophageal junction, then measure the esophagus from the hiatus to the gastroesophageal junction. Next, perform endoscopy and visualize the mucosa clearly to ensure no injuries and insufflate the esophagus in stomach to ensure no air leakage.Begin hiatal repair by performing accrual repair using O silk sutures, applying two to three posterior crural stitches. Pass a 56 French bougie into the esophagus, and with the bougie in place, pass a grasper comfortably into the hiatus. Next for Nissen fundoplication, bring the fundus across the right side, posterior to the esophagus and beneath the vagus nerve.Pass a 58 French bougie into the esophagus and perform a loose fundoplication over the bougie, using three 2/0 silk sutures.
