BACKGROUND

Prosthetic hernioplasty is the most effective method of surgical treatment of median postoperative hernias. Various laxative incisions are widely used, and the measurement of peripheral blood saturation is important in terms of determining the likelihood of an increase in intra-abdominal pressure.

OBJECTIVE

To study the dependence of intra-abdominal pressure and blood oxygen saturation in patients with different incisional hernia repair.

MATERIAL AND METHODS

The study involved 20 patients of different sexes aged 52.5±6.4 years with postoperative median hernias with a hernial gate width of up to 10 cm (W1—W2 SWR-classification) without relapses and infringement. Patients underwent hernioplasty «sublay preperitoneal» according to the classical method (control group) and using wavelike relaxing incision of anterior wall of rectus sheath (main group). We measured size of the hernial gate, intra-abdominal pressure and blood oxygen saturation in all patients at various stages of a clinical study.

RESULTS

Level of intra-abdominal pressure in the main group of patients was significantly lower than in the control group of patients (p=0.05) after surgery. The peripheral blood saturation in patients of the main group immediately after surgery, as well as on the 5th day after its completion, were significantly higher than in the control group (p=0.05).

CONCLUSION

To prevent an increase intra-abdominal pressure and reduce the risk of intra- and postoperative complications, it is important to measure the blood oxygen saturation in patients with incisional hernias. Also it is important to use a wavelike relaxing incision of anterior wall of rectus sheath with prosthetic hernioplasty «sublay». The larger size of the hernial gate indicates a decrease in peripheral blood saturation.
