A 13-year experience with biologic and biosynthetic absorbable mesh reinforced laparoscopic paraesophageal hernia repair.

BACKGROUND

Mesh reinforced cruroplasty during laparoscopic paraesophageal hernia repair remains controversial due to wide variation in surgical technique and mesh composition. This study aims to review outcomes and rates of recurrence following laparoscopic paraesophageal hernia repair (LPEHR) with mesh reinforced cruroplasty utilizing absorbable mesh at a single institution.

METHODS

A retrospective review of all patients who underwent LPEHR with mesh was performed. Medical records were reviewed for patient reported, radiographic or endoscopic evidence of recurrence, defined as > 2 cm of vertical intrathoracic stomach. If no studies were available for review, patients were considered to have no recurrence. Outcomes and mesh-related complications were also reviewed.

RESULTS

Between 10/2008 and 9/2021, 473 patients underwent LPEHR with absorbable mesh; 1.3% type 2 hernias, 86.0% type 3 hernias, 12.7% type 4 hernias. Three types of mesh were used: initially biologic mesh (n = 83), then heavyweight synthetic bioabsorbable mesh (n = 261), and finally lightweight synthetic bioabsorbable mesh (n = 111). There were no significant differences in age, ASA, BMI, gender, smoking status, chronic steroid use, preoperative acid suppression, hernia type, or recurrent hernia between groups. There were no significant differences in 30-day postoperative outcomes. Reflux Symptom Index, GERD-HRQL, and Dysphagia Scores at 1- and 2-year postoperative timepoints were not significantly different. The overall recurrence rate was 16.7%, with no significant differences in recurrence rates between biologic, heavyweight or lightweight biosynthetic absorbable mesh through 2 years after surgery. A shorter median time to recurrence (10 months, p = 0.016) was seen in the lightweight group.

CONCLUSION

LPEHR with absorbable mesh reinforced cruroplasty is feasible and safe, with equivalent patient-reported outcomes, including dysphagia, up to 2-years postop regardless of mesh choice. No significant differences in recurrence rates between biologic, heavyweight, or lightweight synthetic bioabsorbable mesh were seen up to 2 years after LPEHR.
