Prevention of large and giant postoperative ventral hernia prosthetic hernioplasty postoperative complications

Abstract

Aim. To evaluate the effectiveness of regional prolonged irrigation with ropivacaine ozonated solution at large and giant postoperative ventral hernia prosthetic hernioplasty. Methods. 77 patients who underwent a planned surgery for large and giant postoperative ventral hernia from 2010 to 2012 were examined. All patients were distributed to two groups. The main group included 26 patients in whom a polyvinyl chloride catheter was installed in periprosthetic tissue for the wound irrigation using anesthetic (ropivacaine) ozonated solution for regional prolonged anesthesia and wound complications prevention as well as for preoperative preparation and intra-abdominal pressure monitoring for abdominal compression syndrome prevention using the technique developed by authors. The comparison group consisted of 51 patients in whom prevention of wound complications was carried out conventionally, and who received narcotic analgesics. Ultrasonography of postoperative wound area was used for local inflammation intensity assessment. Pain was assessed using numeric visual analogue scale in both groups. Results. 4 (15.4%) patients of the main group developed subcutaneous tissue seroma at the 5-6th day. In comparison group wound complications were registered in 15 (29.4%) patients, including 11 cases of seromas, 2 cases of suppurative inflammation, 1 case of ischemic necrosis of the wound edges, and also an isolated case of limphorrhea which occurred on the first day. The observations showed that the average pain level among patients of the main group was 3.8±0.4 points, compared to the control group - 5.3±0.4 points. Conclusion. Periprosthetic irrigation with ropivacaine ozonated solution provides adequate anesthesia, reduces the number of wound complications and promotes early rehabilitation.
