Effect of Wound Closure Technique on Wound Infection in the Morbidly Obese: results of a randomized trial.
The effect of suture obliteration of the subcutaneous dead space in morbidly obese abdominal wounds was studied in a randomized trial, comparing a pre-fascial retention suture technique (utilized for approximated of the thick panniculus) to controls where the skin was simply closed with staples. The wound infection rates were similar (11.8% for the sutured group versus 12.3% for controls, p 0.4), as were the total wound complication rates (26.5% for sutured group versus 21.9% for controls, p 0.4). Ultrasound study of the wounds closed without suturing the panniculus demonstrated no dead spaces. We conclude that no advantage is to be gained by suturing the subcataneous fat, however thick. The finding is of general application in wound closures involving thick layers of fat.
