Abstract

Abstract: Aim: Patients with incisional hernia with a width greater than 9 centimeters, submitted to Posterior Component Separation Trasversus Abdominis Release, by Department of Emergency and Transplantation Surgery in Varese Hospital, were analyzed to define the modifications in respiratory physiology after surgery. Material and Methods: Patients that underwent Posterior Component Separation were prospectively analyzed by evaluating: volume of laparocele, volume of abdominal cavity and their ratio. Furthermore Pulmonary Peak pressures and Pulmonary Plateau pressures were measured in three different times: at the induction of the anaesthesia, when the mesh was placed and at the closure of the anterior muscular layer. All patients were submitted to a pre-operative simple spirometry, and re-examinated three months after the surgical procedure with the same procedure to check if modifications in their respiratory function were present. Results: Primary results of the study will be shown to define how this surgical procedure impacts on the respiratory function of the patients. The expectation is that an improvement of the respiratory physiology happens independently from a pulmonary pressure elevation which is determinated by the re-allocation of the herniated viscera in the abdomen when the anterior muscular fascia is closed. Conclusions: the aim of this study is to show how, the reconstitution of a functional abdominal wall with an efficient respiratory accessory musculature guaranteed by the laparocele correction with Posterior Component Separation, ensures an improvement of respiratory physiology visible with spirometry, independently from the development of a superior intrathoracic pressure.
