Early Surgical Site Infection Following Tissue Expander Breast Reconstruction with or without Acellular Dermal Matrix: National Benchmarking Using National Surgical Quality Improvement Program

Background Surgical site infections (SSIs) result in significant patient morbidity following immediate tissue expander breast reconstruction (ITEBR). This study determined a single institution's 30-day SSI rate and benchmarked it against that among national institutions participating in the American College of Surgeons National Surgical Quality Improvement Program (ACS-NSQIP). Methods Women who underwent ITEBR with/without acellular dermal matrix (ADM) were identified using the ACS-NSQIP database between 2005 and 2011. Patient characteristics associated with the 30-day SSI rate were determined, and differences in rates between our institution and the national database were assessed. Results 12,163 patients underwent ITEBR, including 263 at our institution. SSIs occurred in 416 (3.4%) patients nationwide excluding our institution, with lower rates observed at our institution (1.9%). Nationwide, SSIs were significantly more common in ITEBR patients with ADM (4.5%) compared to non-ADM patients (3.2%, P=0.005), and this trend was observed at our institution (2.1% vs. 1.6%, P=1.00). A multivariable analysis of all institutions identified age ≥50 years (odds ratio [OR], 1.4; confidence interval [CI], 1.1-1.7), body mass index ≥30 kg/m2 vs. 4.25 hours (OR, 1.9; CI, 1.5-2.4) as risk factors for SSIs. Our institutional SSI rate was lower than the nationwide rate (OR, 0.4; CI, 0.2-1.1), although this difference was not statistically significant (P=0.07). Conclusions The 30-day SSI rate at our institution in patients who underwent ITEBR was lower than the nation. SSIs occurred more frequently in procedures involving ADM both nationally and at our institution

Wide local excision, Mohs micrographic surgery, and reconstructive options for treatment of dermatofibrosarcoma protuberans of the breast: A retrospective case series from Mayo Clinic

Abstract Background Dermatofibrosarcoma protuberans (DFSP) of the breast is a dermal fibroblastic neoplasm requiring wide excisional margins due to recurrence rates ranging from 26 to 60%. The current literature on reconstructive options and utility of Mohs micrographic surgery for DFSP of the breast is scarce. We describe surgical management of DFSP of the breast at our institution with the largest case series reported to date. Methods A retrospective review was performed of women who underwent surgery for DFSP of the breast at our institution between 1990 and 2019. Continuous data was summarized using mean, median, and range; categorical data was summarized with frequency count and percentage. Preoperative lesion size and postoperative defect size were evaluated using 2-sided Fisher exact test, and p-values < 0.05 were considered statistically significant. Results Nine patients underwent wide local excision (WLE) with reconstruction including pedicled latissimus dorsi flaps (n = 2), local flap advancement (n = 2), mastectomy with implant (n = 1), oncoplastic breast reduction (n = 1), and skin grafts (n = 3). Nine underwent Mohs micrographic surgery (MMS) with complex primary closure. Mean postoperative maximum wound defect size for WLE was 10.8 cm versus 7.0 cm for MMS with no statistical significance (p = 0.77). Mean preoperative maximum lesion size for WLE was 6.4 cm versus 3.3 cm for MMS with no statistical significance (p = 0.07). Complications with WLE included wound dehiscence in three patients and seroma in one patient. No complications were reported with MMS and primary closure. Recurrence was reported in one WLE patient, which was successfully detected despite flap coverage and resected without complications. Median follow-up for the patients without recurrence was 5.0 years, with two patients in MMS cohort lost to follow-up. Five-year overall survival was 100%. Conclusions MMS and WLE are both viable surgical options for managing DFSP of the breast. MMS could potentially minimize reconstructive needs due to smaller average defect size and result in fewer complications but may also result in asymmetry. Immediate flap reconstruction, especially in larger defects, can achieve excellent aesthetic outcomes for patients with DFSP of the breast without compromising detection of disease recurrence

A reconstructive algorithm after thigh soft tissue sarcoma resection including predictors of free flap reconstruction

BACKGROUND: Reconstruction of defects of the thigh after oncologic resection plays a vital role in limb salvage. Our goal was to evaluate our institution\u27s experience on thigh sarcomas to develop evidence-based recommendations to guide the reconstructive surgeon, including factors that would predict the need for free flap reconstruction. METHODS: We reviewed all thigh defects requiring plastic surgeon reconstruction following sarcoma resection at our institution from 1997 to 2014. Patient demographics, comorbidities, multimodality therapies, and operative characteristics were analyzed. RESULTS: There were 159 thigh reconstructions. Reconstruction was achieved by primary closure (15%), skin graft (13%), local fasciocutaneous flap (8%), local muscle flap (31%), regional muscle flap (28%), or free flap (4%). For the proximal third of the thigh, the most common flaps were pedicled thigh muscle and rectus abdominis flaps; for the middle third of the thigh, it was pedicled thigh muscle flaps; and for the distal third, it was pedicled gastrocnemius muscle flaps. Factors shown to be predictive of requiring a free flap included wide defects (p = 0.03) and location in the middle third of the thigh (p = 0.001). CONCLUSION: There are multiple options for reconstructing defects from thigh STS. When primary closure and skin grafts are not an option, most defects can be closed with pedicled local or regional muscle or fasciocutaneous flaps. Free flap reconstruction is rarely required but can be necessary when defects are wide or located in the middle third of the thigh

Complications after thigh sarcoma resection.

BACKGROUND AND OBJECTIVES: Standard treatment for extremity sarcoma is limb-sparing surgery often with radiation, but complications occur frequently. We sought to determine factors predictive of wound complications after thigh sarcoma resection and reconstruction while analyzing trends over time. METHODS: We reviewed all thigh defects requiring plastic surgeon reconstruction following sarcoma resection at our institution from 1997 to 2014. Patient demographics, comorbidities, operative characteristics, multi-modality therapies, and complications were analyzed. Wound complications were: infection, dehiscence, seroma, hematoma, or partial/total flap loss. RESULTS: There were 159 thigh reconstructions followed for 30 months on average. Eighty-seven percent of patients underwent radiation and 42% had chemotherapy. Almost half (49.1%) had a complication. The most common wound complication was surgical site infection (23.3%) followed by dehiscence (19.5%), and seroma (10.7%). Less common were partial (2.5%) or total flap loss (0.6%). Reoperation was required in 21 patients (13.2%). Tobacco use, older patient age, cardiac disease, and higher body mass index were independently associated with wound complications. Complications trended towards decreasing over time, but this was not statistically significant. CONCLUSIONS: Tobacco use, cardiac disease, and higher body mass index, but not the timing of reconstruction, appear to increase the risk of wound complications after thigh soft tissue sarcomas resection and plastic surgery reconstruction
