Brief summary
The purpose of the study is to evaluate the success of hiatal hernia repairs in patients with large (\>5cm) or paraesophageal hernias when Ovitex LPR mesh used during the repair.
Detailed description
This is an investigator initiated, single site, single arm study investigating the recurrence rate of hiatal hernia and safety using Ovitex LPR in patients undergoing hiatal hernia repair. Ovitex LPR mesh is a reinforced tissue matrix, comprised of a fine non-absorbable polymer suture interwoven through layers of absorbable biologic material in a "lockstitch" pattern.The biologic material in OviTex, derived from ovine rumen (sheep stomach), serves as the natural building block and is optimized to reduce foreign body response, enable functional tissue remodeling and promote a more natural hernia repair. The interwoven polymer fibers provide additional reinforcement, along with improved handling and load-sharing capability. The permanent polymer fiber (polypropylene) is a standard surgical suture material that is used in hiatal hernia surgery and comprises less than 5% of the final product. Preop details, quality of life questionnaires and surgery details will be collected along with post op GERD (gastro esophageal reflux disease) quality of life questionnaires and barium swallow esophagrams to objectively examine recurrence of hiatal hernia at 1, 3, and 5 years post op. Data will be carefully collected and reviewed for discrepancies and verified with source prior to analysis.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Hiatal Hernia Recurrence as assessed by barium swallow demonstrating axial hernia >2 cm | 5 years | Assess recurrence rates by objective measures when Ovitex LPR permanent polypropylene polymer reinforcement (Ovitex LPR) is placed during robotic-assisted repair of paraesophageal and large (\> 5cm) hiatal hernias (henceforth PEH) using recurrence rate measurements defined as \> 2cm axial hernia by Barium Swallow or endoscopy, if available |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Number of participants with treatment related mesh erosions as assessed by study quality of life questionnaire leading to endoscopy | 5 years | Assess the safety of using polypropylene support related to potential erosion as assessed by presence of symptoms using study quality of life questionnaire leading to endoscopy demonstrating mesh erosion |
