Assessment of Intra-abdominal Pressure During the Perioperative Period of Hernia Repair

Thousands of patients worldwide undergo abdominal surgery every day; 2-11% of laparotomies will progress to an incisional hernia, particularly midline laparotomies, which are associated with higher hernia rates, reaching up to 70% in obese patients (1,2). Long-term recurrence after incisional hernia repair is close to 30% after primary repair and may increase to 70% in cases of iterative (redo) surgery (3). The main risk factors for incisional hernia formation or recurrence include surgical site infection, surgical technique, respiratory insufficiency (COPD), as well as overweight and obesity, the prevalence of which is rapidly increasing. Midline incisional hernias are the most frequent and represent a significant public health issue. In abdominal wall surgery, some teams perform so-called tension-free repairs, whereas others favor repairs under tension. The tension-free concept may be associated with a lower recurrence rate. However, this intuitive concept has never been mechanically defined, using perioperative pressure measurements or surface tension assessment. Few studies have investigated abdominal pressure and muscle tension measurements in relation to abdominal wall surgery. The aim of this study is to evaluate a protocol for measuring abdominal pressures during open repair of midline incisional hernia.
