Efficacy Study of a Selective Chest Wall Restriction Belt in Postoperative of Lung Resection

Comparisons of forced expiratory volume in one second (FEV1) between the two groups at Day 3. The value of FEV1 is standardized with pre-operative one.

Comparisons of pulmonary function test ( forced expiratory volume in one second (FEV1), Forced vital capacity (FVC)) between the two groups. They are expressed as Liters. Before surgery, all days from Day 2 to the patient's exit from hospital (max Day 6) and at the follow-up visit at Month 1. Each value is standardized with pre-operative one.

Comparisons of Peak expiratory flow at cough (PEF) between the two groups. It is expressed as Liters per second. Before surgery, all days from Day 2 to Day 6 and at the follow-up visit at Month 1. Each value is standardized with pre-operative one.

The patient pain is evaluated using the ENS (Echelle Numérique Standard; standard digital scale, score between 0 to 10) for the two groups. The pain is evaluated all days from Day 2 to the patient's exit from hospital, at the weekly phone follow-up until Month 1 and at the follow-up visit at Month 1.

The cough is classified with this scale : 0-dry cough; 1-productive cough without expectoration; 2-productive cough with expectoration; 3-productive cough with important and/or difficult expectoration. It's qualified for the two groups all days from Day 2 to the patient's exit from hospital.

The analgesic drugs are characterized by their class, dose and number of dose taken in the two groups. These elements are evaluated all days from Day 2 to the patient's exit from hospital, at the weekly phone follow-up until Month 1 and at the follow-up visit at Month 1.

Use of aerosol therapy (yes/no) and class of drugs. Use of antibiotic therapy (yes/no), type of drugs and expected duration of treatment. Use of loco-regional anaesthesia (yes/no), modality of administration and type of drugs. These elements are evaluated all days from Day 2 to the patient's exit from hospital, at the weekly phone follow-up until Month 1 and at the follow-up visit at Month 1.

Number and classification of post-surgery complications.For the two groups from Day 1 to the follow-up visit at Month 1.

The length of hospital stay in days for the two groups.

The EQ-5D is a generic preference-based measure that indirectly measures the utility for health that generates an index-based summary score based upon societal preference weights. The EQ-5D-5L consists of 6 items that cover 5 main domains (mobility, self-care, usual activities, pain/discomfort, and anxiety/depression) and a general visual analog scale (VAS) for health status. Each item has 5 response levels ranging from level 1 (no problem or none) to level 5 (unable to perform activity). The VAS ranges from 0 (worst health status) and 100 (best health status). Comparison between the two groups preoperatively, at the patient's exit from hospital, at Day 15 during the phone follow-up and at the follow-up visit at Month 1.

Comparions of the number of the consumption of hospital care (medical acts and consultations, rehospitalization) between the two groups from Day 1 to the follow-up visit at Month 1.

Only for the medical device's group.

• Qualitative questionnaire specifically created about efficacy and acceptability of the medical device at the patient 's exit from hospital. This questionnaire uses Likert scale from 0 to 10 to evaluate each use step of the medical device, closed-ended questions and open questions for comments. A descriptive analysis will done with the answers
• Closed-ended questions will be asked in a questionnaire specifically created about acceptability and use of the medical device. A descriptive analysis will done with the answers and will be asked during the weekly phone follow-up.

Only for the medical device's group. This questionnaire uses Likert scales from 0 to 10 to evaluate each use step ofthe medical device, closed-ended questions and open questions fr comments. It will be asked at the end of the clinical study at each caregiver.
