Effect of hernia mesh weights on postoperative patient-related and clinical outcomes after open ventral hernia repair. A randomized clinical trial.

This study evaluated two different weights of hernia mesh in 350 procedures. Compared with standard mesh, medium weight polypropylene mesh did not reduce postoperative pain, quality of life or hernia recurrence after one year: 7 versus 8 per cent.

Comment: The weight of mesh seems unimportant.
