The primary aim of this study is to detect incidence of mesh infection in cases presented with obstructed or strandulated hernia.A prospective controlled study will be carried out after obtaining written informed consent from all patients and approval of the ethics committee of the faculty of medicine, Assuit University.

There is controversy regarding the use of prolene mesh in cases of obstructed and strangulated hernia. The main aim and objective of this prospective study is to evaluate the outcomes and incidence of mesh infection in hernioplasty in emergency situations like obstructed and strangulated hernia .Hernioplasty is the most common surgery for hernia repair with Propylene mesh,but the use of synthetic prosthesis is associated with increase risk of developing a prosthetic infection that may manifest after time as subtle symptoms in the form of fever, myalgia, erythema of overlying skin and in some cases as chronic discharging sinus(1). clinicians have been challenged in the past few years by an increasing variety of novel non-infectious and infectious complications following the widespread use of meshes after open repair of hernias this incidence is influenced by underlying co-morbidities, the type of mesh, the surgical technique and the strategy used to prevent infections. An approach that combines medical and surgical management is necessary for cases of mesh infection.(2)
