Mesh expansion as the cause of bulging after abdominal wall hernia repair

A swelling after abdominal wall repair can be caused by bulging of the mesh. A progressive bulging might be the result of failure of the mesh implant due to elongation. Mesh characteristics should be considered when choosing a feasible and suitable mesh for abdominal wall reconstruction. Clinical distinction between recurrent hernia and mesh bulging is difficult but therapeutically irrelevant in symptomatic patients.
