Application of a subcutaneous negative pressure drain without subcutaneous suture: impact on wound healing in gynecologic surgery

ObjectiveTo evaluate the surgical outcome of a subcutaneous negative pressure drain without subcutaneous suture on wound healing in women undergoing abdominal gynecologic surgery.Study designThe medical records of total 322 patients who underwent abdominal surgery, including cytoreductive surgery for ovarian cancer, between March 2010 and January 2013 were reviewed retrospectively. Patients were divided into two groups by the presence of subcutaneous negative pressure drains without subcutaneous suture, or suture without drainage.ResultsPatient's characteristics in the two groups were not statistically different. Among all patients, the 71 patients who had a subcutaneous wound drain achieved a higher rate of clear healing (97.2% vs. 88.8%; p = 0.033): 100% vs. 98.0% (not significant) in 126 benign and 95.6% vs. 82.8% (p = 0.032) in 196 malignant disease patients. In a multivariate analysis, wound drain placement was an independent prognostic factor affecting the surgical wound outcome; the disruption (OR, 0.100; 95% CI, 0.021-0.485; p = 0.004) rate was significantly lower with subcutaneous negative pressure drain. Placement of a subcutaneous negative pressure drain without subcutaneous suture resulted in clinical benefit, such as shorter admission duration (median, 8 vs. 11 days; p = 0.021).ConclusionsApplication of subcutaneous negative pressure drain is one of the effective and easy ways for clearer wound healing after major gynecologic surgery for malignant disease.
