Utility of Omentoplasty in Mediastinitis Treatment following Sternotomy.

BACKGROUND: Mediastinal infection is one of the most serious complications that occurs following open-heart surgery by sternotomy. In the present study, omentoplasty was initially and aggressively used to treat the infection and prevent the recurrence caused by bones in cases of mediastinitis following open-heart surgery at our clinic.

METHODS: Among the 3656 patients who underwent surgery at our department of cardiovascular surgery between January 1996 and December 2012, omentoplasty as a treatment for mediastinitis was applied to 19 (0.51%) patients (of which 13 were males) following sternotomy. The cases were revised on the 15th day following the first surgery and/or when there was a suspicion of mediastinal infection. The necrotic skin, subcutaneous tissue, and bone tissue were resected, and all the affected sternal tissues were removed until healthy hemorrhagic areas were reached.

RESULTS: The average age of the patients was between 49 and 81 years (mean: 65.7 ± 10.5 years). The mean age of the men was 66.08 ± 12.7 years (age range: 49-81 years) and that of the women was 63.2 ± 6.8 years (age range: 55-71 years). The male to female ratio was 2:1, and in both the male and female groups, the approximate age ranged from 55 and 70 years. In the intraoperative cultures received from wound cases, the most common agent of infection was methicillin-resistant coagulase-negative staphylococci. Purulent leaks from eight patients stopped in approximately 4 days. Purulent leaks from the other 11 patients continued until the 6th day, and thus, medical dressing also continued, after which the leaks stopped on the 15th day. The approximate postoperative hospital stay was 32 days (range: 13-63 days).

CONCLUSION: Omentoplasty in heart surgery can be considered an effective method when used to control infection and treat secondary poststernotomy mediastinitis.
