Women make up an estimated 10% of the veteran population.1 The US Department of Veterans Affairs (VA) projected that there would be an increase of 18,000 female veterans per year for 10 years based on 2015 data. The number of women veterans enrolled in the VA health care increased from 397,024 to 729,989 (83.9%) between 2005 and 2015.2 This rise in the number of enrolled women veterans also increased the demand for female-specific health care services, such as breast reduction surgery, a reconstructive procedure provided at the Malcom Randall VA Medical Center (MRVAMC) federal teaching hospital in Gainesville, Florida.
Patients who experience symptomatic macromastia will report a history of neck and shoulder pain, shoulder grooving from bra straps, inframammary intertrigo, difficulty finding clothes that fit, and discomfort participating in sports. For the treatment of symptomatic macromastia, patients report a high satisfaction rate after breast reduction surgery.3-5 Unfortunately, the complications from the surgery can significantly disrupt a woman’s life due to previously unplanned hospital admissions, clinic appointments, wound care, time off work, and poor aesthetic outcome. Faculty awareness of a large number of complications for patients after breast reduction surgery prompted the MRVAMC Plastic Surgery Service to establish a stricter surgical screening protocol using body mass index (BMI) values and negative nicotine status to help patients be healthier and reduce the potential risk before offering surgery. A medical literature search did not find an existing study on veteran-specific breast reduction surgery.
Methods
The University of Florida and North Florida/South Georgia Veterans Health System Institutional Review Board approved a retrospective chart review of all breast reduction surgeries performed at MRVAMC over a 20-year period (July 1, 2000-June 30, 2020). Electronic health records were queried for all primary bilateral breast reduction surgeries performed for symptomatic macromastia using Current Procedural Terminology code 19318. Potentially modifiable or predictable risk factors for wound complications were recorded: nicotine status, BMI, diabetes mellitus (DM) status, skin incision pattern, and pedicle location. Skin incision patterns were either vertical (periareolar plus a vertical scar from the areola to the inframammary fold) or traditional Wise pattern (also known as anchor pattern: periareolar scar, vertical scar to inframammary fold, plus a horizontal scar along the inframammary fold) as seen in Figures 1 and 2. The pedicle is the source of blood supply to the nipple, which was documented as either from the inferior aspect or the superior or superior/medial aspect.
For this study, the blood supply from the superior and superior/medial was logged in the same category. Records were reviewed 3 months after surgery for documentation of local wound complications, such as hematoma, infection, wound breakdown, skin necrosis, and nipple necrosis. Major complications were defined as requiring an unplanned hospital admission or urgent return to the operating room. A χ2 test using a P value of < .05 was used to determine statistical significance between the incidence of wound complications and the individually identifiable variables.
Results
One hundred fifteen bilateral breast reduction surgeries were performed at MRVAMC over a 20-year period. Patient median age was 43 years. Median combined specimen weight was 1272 g. Forty-eight (41.7%) wound complications were documented, including 8 (7%) major complications. Most complications were identified in the first 7 years of the study before the new protocol and consult template became active. The new template resulted in the local complication rate dropping from 62% (July 2000-June 2007) to 26% (July 2007-June 2020). BMI > 32 (P = .03) and active nicotine use (P = .004) were found to be statistically significant independent risk factors for wound complications. Median BMI for all patients was 30. DM status (P = .22), skin incision pattern (P = .25), and pedicle location (P = .13) were not found to be predictors of wound complications (Table). There was no significant change in the incidence of major complications before and after the new protocols were enforced.
Discussion
Breast reduction surgery is an elective reconstructive option to treat symptomatic macromastia. There are several accepted ways to do the reduction surgical procedure where the blood supply (pedicle) to the nipple can vary and the visible scars can be in a horizontal, vertical, or Wise pattern. Technique is usually based on surgeon training, comfort, and preference. There are several known complications specific to this operation that include asymmetry, changes in nipple sensation, unattractive scars, diminished ability to breastfeed, and wound complications.5-7 Wound complications include seroma, hematoma, dehiscence, infection, wound breakdown, skin necrosis, and nipple necrosis.
This study focused on wound complications with the objective of identifying and modifying risk factors. Two known risk factors documented in the literature, nicotine use and obesity, already had been addressed by our service, and results were known anecdotally but had not been previously verified. This study also looked at other potential risk factors, including the pedicle location, skin incision, and DM status.
Residents or fellows participated in all the surgeries. An outcome analysis from The American College of Surgeons National Surgical Quality Improvement Program database from 2005 to 2011 found that resident participation was associated with morbidity, including wound complications.8 This study was performed at a federal hospital with a complexity level 1a rating, which is designated based on the highest level of patient volume, risk, teaching, research, intensive care unit beds, and specialty services.9 The hospital is closely affiliated with a level 1 trauma center and teaching hospital; therefore, resident and fellow participation is not a modifiable risk factor.
