Biologic prosthesis reduces recurrence after laparoscopic paraesophageal hernia repair: a multicenter, prospective, randomized trial. Ann Surg 2006: 244: 481¿490.

Published: 1st January 2006

Authors: Oelschalger B, Pellegrini C, Hunter J, Soper N, Brunt M, Sheppard B et al.

Conclusion

The use of small intestine submucosa instead of prosthetic mesh reduced the rate of recurrent hernia after six months (4/51, 9 per cent vs. 12/57, 24 per cent, P=0.04), though both groups experienced similar improvements in quality of life.
