Prolonged postoperative antibiotic administration reduces complications after medial thigh lift.

There is widespread consensus that there is no indication for postoperative antibiotic administration after elective surgery. However, medial thigh lift (MTL) remains a procedure with a notoriously high rate of wound-healing disorders and infections. This study investigates the correlation between prolonged antibiotic administration and complications after MTL in massive weight loss patients. We performed a single-institution retrospective review of 121 patients undergoing MTL between 2009 and 2020. Data on postoperative outcome, demography, surgery and comorbidities were collected. All patients received intravenous antibiotics preoperatively. One group was continued on oral antibiotics for two weeks postoperatively. Complications and surgical site infections were observed and evaluated. There was no difference between the groups regarding age, BMI, or presence of obesity-associated risk factors. We observed complications in 76 patients (71%), with 60 (56%) minor and 16 (15%) major complications. The group without prolonged antibiotic administration had a higher number of total complications (OR 3.5; p = 0.0037), major complications (OR 4; p = 0.01), and wound infections (OR 6.8; p = 0.0004). Logistical regression analysis showed that this effect was independent of type of weight loss, resection volume, and age. Reduction of major infections by prolonged antibiotics was, however, dependent on BMI Δ. No side-effects associated with antibiotics were registered in this series. This study suggests that prolonged antibiotic administration may decrease complications in MTL. We thus continue to use prolonged antibiotic administration after MTL. Further research is needed to determine the optimal duration of antibiotic treatment. Level of Evidence: Level IV: therapeutic study.

The Edmonton Obesity Staging System as a predictor for postoperative complications after medial thigh lift in massive weight loss patients.

BACKGROUND: This study investigates the correlation between the Edmonton Obesity Staging System (EOSS) and the occurrence of postoperative complications after medial thigh lift in formerly obese patients. PATIENTS AND METHODS: A single-institution retrospective review of patients undergoing medial thigh lift between 2009 and 2019 after massive weight loss. Data on demography, comorbidities, surgery, and postoperative outcome were extracted from patients' charts. Patients were grouped into EOSS categories. Complications were classified into minor and major. Logistic regression analysis was performed to determine the association between risk factors and complications. RESULTS: One hundred and eight patients were included in the study. Complications occurred in 76 (70%) of the patients, most of which were minor (60/108, 56%). Complications increased with increasing EOSS stage, and all EOSS 3 patients had complications. Classification as EOSS 2 or 3 significantly associated with occurrence of postoperative complications (OR 99.3, p<0.001) as well as minor and major complications individually (OR 3.1 and 6.5, p<0.05). This effect was independent of body mass index (BMI), maximum BMI loss, type of weight loss, volume of liposuction, weight of resected tissue, and type of surgery. CONCLUSION: EOSS is a robust and independent predictor for postoperative complications in medial thigh lift surgery after massive weight loss.
