Brief Summary

CycloMesh is a polyester visceral implant functionalized by drug delivery systems directly on its surface, targeting a unique intervention, a slow anesthetic release and an in situ activity. Based on the fact that cyclodextrins are capable of forming inclusion complexes with amino-amide anaesthetic agents, ropivacaine and cyclodextrins were combined on a commercial visceral mesh.This enables CycloMesh to release ropivacaine for a sustained period in order to improve patient's comfort after inguinal hernia surgery.

The underlying hypothesis of this work is that clinical gain is achieved by adding a drug delivery system to visceral mesh for the local and prolonged delivery of ropivacaine. This should results in an improvement in quality of life, a reduction in pain and a faster returning to work following treatment of inguinal hernia by lichtenstein technique.

Arm && Interventions

Group	Intervention	Description
CycloMesh™ soaked in ropivacaine hydrochloride 10mg/mL	Inguinal hernia repair with CycloMesh™ soaked in ropivacaine hydrochloride 10mg/mL	The surgical technique for the inguinal hernia repair is the surgeon's usual technique: open surgery (Lichtenstein technique). CycloMesh™ device (soaked in ropivacaine hydrochloride 10mg/mL) is positioned once the surgery for the inguinal hernia repair has been performed.
CycloMesh™ soaked in saline solution 9°/°°	Inguinal hernia repair with CycloMesh™ soaked in saline solution NaCl 9°/°°	The surgical technique for the inguinal hernia repair is the surgeon's usual technique: open surgery (Lichtenstein technique). CycloMesh™ device (soaked in saline solution) is positioned once the surgery for the inguinal hernia repair has been performed.

Primary Outcome Measures

Name	Time	Method
Pain intensity after treatment of inguinal hernia by lichtenstein technique under general anesthetic will be assessed 6h post-operative using Visual Analogic Scale (VAS).	6 hours post-surgery	The visual analogue scale is a graduated ruler from 0 to 10 cm where 0 indicates that the subject has no pain and 10 cm represents the maximum pain the subject can tolerate. It is a self-assessment scale and is sensitive, reproducible, reliable and validated for both acute and chronic pain situations.; Pain assessment will be performed 6 hours after implant placement and during cough effort.

Secondary Outcome Measures

Name	Time	Method
Number of patients presenting at least one AE related to the the device implantation	All study period (24-months)	The safety and tolerability end points will be will be as follows: number of patients presenting at least one AE related to the the device implantation
Hospitalization lenght (in hours)	1 week post-surgery	In case of delayed discharge (the day after the surgery or prolongation of hospitalization), the reasons of prolonged hospital treatment will be collected
The rate of foreign body sensation at 12 and 24 months postoperative	12-months after surgery and 24-months after surgery	Foreign body sensation is assessed by answering yes or no to the question: do you feel a foreign body in the groin
Time to return to work or activity post-surgery	Day 1, Day 7 and 1 month post-surgery	The Time to return to work or activity following surgery will be evaluated in terms of the number of days between hospitalisation and resumption of activity
Satisfaction of the surgeon and unit staff regarding the use of CycloMesh will be evaluated using a satisfaction questionnaire	Day 0	Surgeon and unit staff will have to answer to a questionnaire concerning the packaging of CycloMesh, the technical characteristics of the implant (flexibility, porosity, etc.), its size, time imbibition of CycloMesh, etc.
Pain intensity at 1 month post-surgery will be assessed using a Visual Analogic Scale (VAS)	1 month post-surgery	Pain intensity at 1 month post-surgery will be assessed, using a visual analogic scale, during a visit to the surgeon and in 3 different situations: at rest, walking and during cough effort.The visual analogue scale is a graduated ruler from 0 to 10 cm where 0 indicates that the subject has no pain and 10 cm represents the maximum pain the subject can tolerate.It is a self-assessment scale and is sensitive, reproducible, reliable and validated both in acute pain and chronic pain situations.
Pain intensity back to home (Day 0) and Day 1 to 3 will be assessed using a Visual Analogic Scale (VAS)	Back to home (Day 0) at 8pm and 10 pm, Twice a day (8 am and 8 pm) at Day 1, Day 2 and Day 3	Pain intensity will be reported by the patient on a log book using a Visual Analogic Scale . The visual analogue scale is a graduated ruler from 0 to 10 cm where 0 indicates that the subject has no pain and 10 cm represents the maximum pain the subject can tolerate
Duration of surgical time from the first incision until wound closure (in minutes)	At the moment of wound closure	Duration of surgical time from the first incision until wound closure will be calculated in minutes
The amount of consumed analgesic will be assessed using post-operative data and data reported by the patient on a log book	7 days post-surgery period	The amount of consumed analgesic will be measured by calculating the number of patients who have consumed analgesic during the 7 post-operative and antalgic intake (in mg) during the 7 post-operative
