Beahm MD, FACS, Robert L Walton MD, FACS and David W Chang MD,FACS INTRODUCTION: Obesity has become a nationwide epidemic. The obese patient presents a highly problematic, yet growing population of patients presenting for breast reconstruction. Donor and recipient complications with autologous flaps appear to be higher in this group, leading some authors to recommended implant reconstruction in these patients, yet prosthetic options are limited due to inadequate size and shape.1-9 (Figures 1 and 2) A number of surgeons refuse to operate or limit their options for breast reconstruction in the very obese patient due to the potential for high complication rates. While unfavorable outcomes have stifled interest in breast reconstruction in the very obese, objective criteria are generally lacking. Currently there are no established clinical recommendations to objectively guide decision making for breast
reconstruction in the very obese patient. METHODS: A retrospective review of outcomes of breast reconstruction in obese patients was conducted over a 15 year period (1/1/1990 to 1/1/2005). Analysis criteria utilized stratified Body Mass Indices (BMI) (25-29.9, 30-349, 35-399, and >40) These patients were matched to normal weight patients (BMI < 24.9) by age and type of reconstruction including autologous flaps from the lower abdominal wall (Transverse Rectus Myocutaneous (TRAM), Deep inferior Epigastric (DIEP) and Superficial Inferior Epigastric (SIEA) flaps); Latissimus Dorsi (LD) flaps (with and without implants), and implant only methods. Outcomes analysis included assessment of complications including: fat necrosis, flap loss (total or partial), delayed wound healing (donor and/or recipient sites) abdominal wall complications in TRAM flap patients such as chronic pain, bulge, hernia, infection; length of hospital stay and medical complications such as Pulmonary embolus(PE)
and deep vein thrombosis(DVT) in a comparative analysis between the groups, including the prevalence of premorbid conditions such as Diabetes mellitus (DM) and coronary artery disease (CAD) and overall aesthetic outcome. Where possible, the decision making process for the type of reconstruction, such as the indications cited for or against immediate or delayed reconstruction, was assessed.

Source: http://www.doksinet RESULTS: The BMI in 3518 study patients ranged from 15.2 to 599 The mean BMI of the patients treated was noted to increase annually (24.2 to 268) over the study period The complication rate was comparable for all the BMI indices <35. In patients with a BMI ≥35 a significant increase in post-operative complications was noted in
all methods of reconstruction. Complication rates: 50% vs. 34% (TRAM); 333% vs 225% (Implant); 40% vs 33 %( LD); Overall 39% vs. 309% While complications increased with patients with a BMI over 35 and approached 100% in those with a BMI over 40 there was no linear correlation in this relationship. In a focused study of patients from 2000-2005 assessment of patient satisfaction and overall aesthetic outcome was deemed lower in patients presenting for breast reconstruction with a BMI ≥ 35. CONCLUSION: We have demonstrated an increased post-operative complication rate following breast reconstruction in patients with a BMI ≥35 compared to patients having a BMI <35. Reconstructive outcome satisfaction rates in these massively obese patients also appear to be low compared to breast reconstruction in thinner patients. These data provide argument for reassessing our approach to management of breast defects in obese patients having a BMI >35. Prospective study is warranted to
develop an appropriate treatment algorithm that will optimize surgical outcomes in this select patient group. Figure 2: Same patient seen in figure 1.
