Biologic prosthesis to prevent recurrence after laparoscopic paraesophageal hernia repair: long-term follow-up from a multicenter, prospective, randomised trial. J Am Coll Surg 2011; 213: 461-468.

Published: 21st December 2011

Authors: Oelschlager BK, Pellegrini CA, Hunter JG, Brunt ML, Soper NJ, Sheppard BC et al.

Conclusion

Some 72 of the original 108 patients were available for study after a median of 58 months. Symptom control was equivalent between the groups. Recurrent hiatus hernia was recorded in 59 per cent after primary repair and 54 per cent with the biologic prosthesis.
