Clinical Trial Summary

Incisional hernia is one of the most common complications of abdominal surgery and carries a significant burden for both patients and the economic health service. However, no consensus for the surgical treatment of incisional hernia in contaminated field is currently available. The purpose of the COMpACT-BIO study is to investigate the clinical and economic benefit of the use of biosynthetic mesh in contaminated incisional hernia repair.

Description:

The current standard of incisional hernia repair is reinforcement with permanent synthetic mesh. However, permanent synthetic mesh is contraindicated in contaminated surgical field due to higher risk of postoperative infection. In order to resist to infection, absorbable meshes, such as biological and biosynthetic meshes, have been developped. However, some controversies exist about the clinical benefit of biological meshes in the long term. Reasons for theses controversies are their overall risk of complication and recurrence and the lack of consensus in which surgical technique to apply. Moreover, the financial cost of biological meshes is very high. Recently developed, biosynthetic meshes appear to be a promising option ; Compared to biological meshes, they seem to have several advantages. However, such data demonstrating the beneficial use of biosynthetic mesh in contaminated incisional hernia repair is not available. In this regard, the COMpACT-BIO study aims to investigate the clinical and economic benefit of the use of biosynthetic mesh in contaminated incisional hernia repair in comparison to the standard of repair. This is a multicenter, prospective, longitudinal and randomized study, which also offers a standardized technique of repair.

Intervention

Procedure:
• Incisional hernia repair with reinforcement of biosynthetic mesh
The biosynthetic mesh (Phasix or Bio-A meshes) will be placed as a sublay in the retromuscular position to reinforce midline fascial closure. All the surgical procedure (including placement and fixation of the mesh) will be performed according to a standardized protocol.
• Incisional hernia repair with simple suture or synthetic mesh reinforcement.
Based on the discretion of the surgeon, the incisional hernia repair will be done by simple suture or by synthetic mesh reinforcement. All the surgical procedure (including placement and fixation of the mesh if applicable) will be performed according to a standardized protocol.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Rate of incisional hernia recurrence	The rate of incisional hernia recurrence will be evaluated by radiologic imaging.	3 years after surgery
Secondary	Days of hospitalization related to incisional hernia repair	Number of days of hospitalization related to hernia repair-related complications will be reported.	For 3 years after surgery
Secondary	Incidence of re-operation related to incisional hernia repair	Incidence of incisional hernia repair-related complications leading to re-operation will be reported.	For 3 years after surgery
Secondary	Incidence of wound events	Incidence of incisional hernia repair-related wound complications, such as wound infection will be reported.	1 month from surgery date, then 3-, 6- 12-, 24- and 36 months from surgery date
Secondary	Incidence of revision surgery or interventional radiologic procedure	Incidence of revision surgery or interventional radiologic procedure related incisional hernia repair-related wound complications will be reported.	1 month from surgery date, then 3-, 6- 12-, 24- and 36 months from surgery date
Secondary	Rate of early incisional hernia recurrence	The rate of incisional hernia recurrence evaluated by physical examination and then confirmed by radiologic imaging will be reported.	1 month from surgery date, then 3-, 6- 12-, 24- and 36 months from surgery date
Secondary	Incisional hernia specific quality-of-life assessment	Self reported clinical symptoms before and after incisional hernia repair will be done using a modified version of the Carolina Comfort Scale . Severity of pain and discomfort pre and post repair will be measured during different daily activities (item). Each item is scored 0-5 (0= no symptom ; 5= worst symptom).	Pre and post-surgery (1 month from surgery date, then 3, 6, 12, 24 and 36 months from surgery date).
Secondary	Number of healing days	At each clinical examination, the time between surgery and the end of median scar care will be measured.	1 month from surgery date, then 3-, 6- 12-, 24- and 36 months from surgery date
Secondary	Rate of screening failure	The proportion of patients who did not receive the surgical procedure proposed by the study, and the related reasons of screening failure will be reported.	48 months after the start of the study
Secondary	Assessment of health care consumption related to health care status	The cost / quality ratio will be measured using the consumption of health care and the health status. In one hand, each health care action will be reported (by the patient or the caregiver) and then the total cost relative to the health care will be measured. In another hand, self-reported health status before and after incisional hernia repair will be done using the EQ-5D-5L questionnaire.	pre and post-surgery (1 month from surgery date, then 3, 6, 12, 24 and 36 months from surgery date).
