OviTex Reinforced BioScaffolds in Hiatal and Inguinal Hernia Repair

TELA Bio®, Inc., announced that two papers have been published reporting on recent clinical results with the use of OviTex RBSs (a series of patients).  OviTex RBSs are a distinct class of surgical implants that integrate biologic and synthetic materials in a unique embroidered construction that allows movement of fluid and cells through the construct.

“As we continue to work to expand patient access and provide OviTex RBSs to hospital networks across the U.S., we also remain focused on collecting important feedback and real-world insights from surgeons who now have extensive experience with nearly 3,000 hernia repair procedures completed to date,” said Maarten Persenaire, chief medical officer of TELA Bio. “We are pleased to announce the publication of two new papers that evaluate OviTex RBSs performance in hiatal and inguinal hernia repair surgeries. The results demonstrate clinical outcomes we have always hoped to achieve, reinforcing the repairs while also providing benefits in pain management.”

A paper published in the Journal of the Society of Laparoscopic Surgeons is the first reported series on the use of OviTex RBSs in hiatal hernia repairs. A retrospective chart review was conducted for 25 consecutive patients undergoing laparoscopic or open hiatal hernia repairs with OviTex RBSs. There were no reported hiatal hernia recurrences. Reinforcement of the crural repair was accomplished in all cases, and fundoplication was constructed in all but one patient. Good to excellent symptom control or resolution was achieved for heartburn (95%), dysphagia (94.7%), regurgitation (100%), nausea and vomiting (100%), dyspnea (100%), and chest pain or discomfort (85.7%).

“As the first biological repair material that is reinforced with resorbable or permanent suture, OviTex RBSs represent a new paradigm in hernia repair,” said Michael Sawyer, MD, FACS, general surgeon at Comanche County Memorial Hospital and author of the paper. “The use of OviTex RBSs has been associated with excellent early patient outcomes in hiatal hernia repairs, and we look forward to conducting long-term follow up and additional studies to confirm these results.”

A separate paper published in the International Journal of Surgery Open evaluated the role of OviTex RBSs in inguinal hernia repair to help reduce the incidence of chronic postoperative pain. Data from 31 consecutive patients who had an inguinal hernia repaired using an open Lichtenstein technique with OviTex RBSs was collected. There were no reported recurrences during the postoperative period. There were also no complications that required surgical intervention and no reported surgical site infections for 30 days postoperatively. No patients reported chronic postoperative inguinal pain, and no OviTex RBSs required explantation for infection, chronic pain, meshoma or any other reason.

“Chronic postoperative inguinal pain represents one of the most frequent and dreaded causes of inguinal hernia complications,” said Stephen Ferzoco, MD, Boston-based hernia surgeon and author of the paper. “It is encouraging to find that no patients reported any postoperative pain that was disabling or lasted beyond three months when OviTex RBSs were used in the repair, which suggests the novel surgical mesh may minimize the inflammatory response seen in many synthetic hernia mesh patients. Importantly, none of these patients required a narcotic pain medications refill.”
