Omental transposition flap for sternal wound reconstruction in diabetic patients.

In 2004, we published our 12-year experience with tissue transfer for deep sternal wound infection after median sternotomy, finding increased rates of reoperation for diabetic patients. Therefore, we decided to alter our treatment approach to diabetic patients to include sternal debridement followed by omental transposition. Eleven diabetic patients underwent omental transposition by our division during the study period. Hospital records were retrospectively reviewed to determine outcomes and complications. We found that diabetic patients treated after implementation of the new treatment approach were 5.4 times less likely to require reoperation for sternal wound management than were patients in the previous series, most of whom had been treated with pectoralis muscle flaps (95% confidence interval, 0.5- 50.5). By altering our treatment approach to use omental transposition as the initial surgical therapy, we were able to demonstrate a trend toward decreased need for flap revision in diabetic patients.
