Evaluation of Chest Wall Motility After MIRPE

Status Recruiting

Clinical Trial Summary

Pectus excavatum (PE) is the most common congenital deformity of the chest wall and surgical treatment using the minimally invasive technique (MIRPE) is consolidating as the choice to perform PE correction. In this technique, a temporary metal bar is placed in a retrosternal position, pushing the sternum without the need for cartilage resection. Despite the advantages obtained, it is not free from complications, with the displacement of the bar being one of the main problems. Therefore, the aim of this study is to evaluate a new bridging device for the set of two metal bars to be used in the surgical treatment of PE, verifying the clinical and surgical complications and evaluating the change in lung volumes and thoracoabdominal kinematics using optoelectronic plethysmography , preoperatively and 180 days after MIRPE; and also evaluating diaphragmatic mobility via ultrasound examination to assess the craniocaudal displacement of the left branch of the vein preoperatively and 180 days later. There will be 20 participants, who after performing a computed tomography of the chest to obtain the Haller index, clinical and laboratory tests, electrocardiogram and echocardiogram. Participants will be randomized and divided into two groups: 10 control individuals (traditional MIRPE technique used in the Service) and 10 intervention individuals (with bridge fixators developed in partnership with Traumec Tecnologia e Implantes, Brazil). The effectiveness of the fixators will be evaluated by the degree of displacement of the bars, using a mathematical formula, using a lateral chest X-ray in the immediate postoperative period (d0) and another image from the end of the period analyzed (dX), 15, 30, 90 and 180 days after the surgical procedure; evaluation of postoperative pain through the numerical pain scale; use of validated questionnaires on quality of life (physical and mental health) using two instruments, SF-36 and PEEQ. All data obtained between the two groups will be submitted to descriptive and inferential statistics.

Clinical Trial Description

Population to be studied: 20 individuals with pectus excavatum will be selected to undergo minimally invasive repair of pectus excavatum (MIRPE). Participants will be randomized into two groups: control and intervention group. In the latter, two metal bars and the bridge model fastener will be used as proposed in this study. The preoperative evaluation consists of anamnesis, physical examination, and laboratory tests. An electrocardiogram and echocardiogram will be performed to assess the participants' cardiac function. A computed tomography (CT) scan of the chest will also be performed to obtain the Haller index, as well as an analysis of lung volumes and thoracoabdominal kinematics and diaphragmatic mobility. Participants will also answer the quality of life questionnaires that will be repeated postoperatively. Participants will undergo minimally invasive repair of pectus excavatum (MIRPE) with one or two metal bars according to randomization. In the postoperative period, the displacement of the metal bars will be evaluated through chest X-ray and pain scale evaluation. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
