[Identification of an objective reference parameter for the reconstruction of a large incisional hernia following...

Repairing a parietal defect of a large incisional hernia should not be limited to the closure of the breach by means of the modern biocompatible prosthetic sheets, but must also be able to restore a correct intra abdominal pressure, otherwise the derangement from the normal respiratory dynamics and the circulatory stasis in the abdominal veins and in those of the lower limbs remain unaltered. Over-correcting the parietal abdominal tension on the contrary can cause a dangerous compartmental syndrome. The attempts of an intraoperative measurement of the correct intra abdominal pressure restoration has been generally hampered from the condition of curarization of the patient during the operation. Using the automatic mechanical ventilator fixed at volume and not at pressure priority, as usual, can offer the possibility to calibrate, following objective parameters, the propriety of the surgical repair still during the final phases of the reparative operation. The simplicity and ingenuity of the here proposed method and the normal availability in every operative theatre of the necessary means for this measurements described, requires attention among the surgeons and a large diffusions of its simple use.
