Filter by:The notable development and diffusion of prosthetic surgery of the abdominal wall over the last few years has led to the introduction of light weight meshes. The efficacy of inguinal hernia repair with light weight prosthesis, as well as the better or worse biotolerability with respect to those of light weight, remains questionable in literature, where a clear answer still remains to be given. If there exists a connection between the quantity of material implanted, the immunological reaction to the mesh, the induced oxidative stress and the degree of cicatrization, and consequently the long-term result of the efficacy of the operation, remains to be demonstrated. There are few studies on the immunological reaction to polypropylene meshes, and none on the oxidative stress induced by the mesh. Moreover, only one study has been published that clearly correlates the immunological reaction to the amount of prosthetic material, but was carried out on only a few patients. The aim of this research is to show if there is a relationship between the amount of prosthetic material used and immunological reactions as well as postoperative oxidative stress, and thus to evaluate, if present, the differences in the biological reaction and biotolerability between light-weight and heavy-weight meshes on a statistically significant number of patients.
Background: Large acceptance of mesh reinforcement techniques in groin hernia repair lowered recurrence rates for all techniques. Recurrence rate alone is not the main quality criterion for hernia repair anymore. Chronic significant post operative pain is a common, clinically relevant, poorly understood and poorly studied entity which is 3 to 5 times more common than hernia recurrence. As a subgroup to chronic significant post operative pain or as a separate entity, sexual dysfunction due to ejaculatory and genital pain after inguinal hernia repair may happen in approximately 2.5% of patients. Patient's preoperative psychological profile as well as pain exposure history is showed to be important in the development of chronic significant post operative pain. The objective of this study is to analyse chronic significant post operative pain and the functional outcome status of patients after laparoscopic repair compared to open repair. Methods: A randomized controlled non-blinded clinical trial is designed to compare open inguinal hernia mesh repair with laparoscopic totally extraperitoneal repair on chronic significant post operative pain, pain related sexual function disorders, complications, health related quality of life outcomes, recurrence rates, and cost. Volunteers will be recruited in Geneva University Hospital, department of surgery, visceral surgery unit. Eligibility criteria is male patient aged over 21 years, with reducible inguinal unilateral or bilateral primary hernia who are candidates for elective surgery and medically fit for general anesthesia.130 patients will be enrolled for each group to achieve an α-Level of 0.05 and a power of 80%. Follow-up will take place at 10th, 30th days as well as 3 12 and 24 post operative months by questionnaires and by clinical exam by independent expert. An overall cost-analysis will be realized. Patient enrollment in the study will start in April 2008 and estimated to end in may 2009.
