Prepectoral Wise-Pattern Staged Implant-Based Breast Reconstruction for Obese or Ptotic Patients.

INTRODUCTION: The obese or ptotic breast demonstrates significant difficulty in breast reconstruction after mastectomy with increased rates of perioperative complications compared with the general population, regardless of reconstruction type. Implant-based reconstruction in this patient population with the traditional horizontal elliptical skin-sparing mastectomy tends to have aesthetically displeasing qualities secondary to skin flap redundancy and blunting of the breast contour. Wise-pattern closures have been described with submuscular direct-to-implant and 2-stage reconstructions, with more favorable complication profile when staged. Our study aims to report outcomes and safety of a prepectoral 2-stage wise-pattern closure technique in the obese and/or ptotic population. METHODS: A retrospective chart review was performed to identify all overweight, obese, and/or grade III ptotic patients who have undergone a 2-stage, wise-pattern skin closure with prepectoral placement of tissue expander by a single surgeon. Patient demographics, comorbidities, and perioperative descriptors were reported. Delayed wound healing, infection, seroma formation, and explantation or reoperation were recorded for each patient involved in the study. RESULTS: Thirty-seven obese and/or ptotic breasts among 21 patients underwent immediate prepectoral tissue expander placement with wise-pattern skin reduction closure with mean body mass index of 35.3 kg/m, and 25% of patients were diabetic The most common complication rates by breast were seroma formation (50%) and wound/dehiscence at T-point (28.6%), which all ultimately healed with intervention as described. One major (2.7%) and 1 minor (2.7%) infection were successfully treated with antibiotics. There were no cases of implant exposure. Two operative complex repairs and 1 elective explantation were performed. Diabetes and increasing body mass index were statistically associated with an increased overall perioperative complication rate. CONCLUSIONS: Prepectoral, 2-stage breast reconstruction with wise-pattern skin reduction performs well in obese and/or ptotic patients with favorable rates of perioperative complications. Wound dehiscence was prevalent but managed with wound care when complex repair was not required to expedite adjuvant chemotherapy. Infection rates and reoperation rates were low, and all patients reported positive aesthetic results at the completion of reconstruction.

The oncoplastic reduction approach to breast conservation therapy: benefits for margin control.

BACKGROUND: Reduction mammaplasty during lumpectomy allows more generous resection and minimizes potential for poor cosmesis as compared with breast conservation therapy alone. OBJECTIVES: The authors assessed the benefits of oncoplastic reduction for margin status in patients with breast cancer by conducting a retrospective review of cases of tumor resection alone vs tumor resection with oncoplastic reduction. METHODS: Patients with breast cancer who underwent lumpectomy performed by a single oncologic surgeon between 2009 and 2013 were included. Patients were stratified into 2 groups based on surgical procedure: tumor resection with oncoplastic reduction (group 1) vs tumor resection alone (group 2). Patient demographics including risk factors, diagnosis, cancer stage, and procedure type were recorded. Tumor size, specimen weight, width of narrowest margin, and receptor status were determined. Outcome variables included margin positivity (≤1 mm), need for re-excision, and conversion to completion mastectomy. RESULTS: A total of 222 breasts from 207 patients were included in the study: 83 in group 1 and 139 in group 2. The patients in group 1 had a lower incidence of positive margins and wider free surgical margins, required re-excision less often, and went on to completion mastectomy less often. Patients in group 1 were younger and had cancer that was more advanced. When controlling for these variables on multivariate regression analysis, the oncoplastic technique was independently associated with fewer positive margins and fewer instances of re-excision. CONCLUSIONS: The oncoplastic reduction technique achieves wider free margins and less often necessitates re-excision or subsequent mastectomy. The long-term oncologic effect of this approach deserves further study. LEVEL OF EVIDENCE: 4.

Hereditary multiple intestinal atresias: 2 new cases and review of the literature.

Intestinal atresias are a common cause of newborn bowel obstruction (Dalla Vecchia LK, Grosfeld JL, West KW, et al, Intestinal atresia and stenosis: a 25-year experience with 277 cases. Arch Surg 1998; 133[5]:490-496). Hereditary multiple intestinal atresias, first reported by Guttman et al in 1973, is the rarest form of multiple atresias (Guttman FM, Braun P, Garance PH, et al, Multiple atresias and a new syndrome of hereditary multiple atresias involving the gastrointestinal tract from stomach to rectum. J Pediatr Surg 1973;8:633-640; Bass J, Pyloric atresia associated with multiple intestinal atresias and immune deficiency. J Pediatr Surg 2002;37:941-942.). It has been proposed to be autosomal recessive, to involve atresias in a variable combination of sites from stomach to rectum, and to be universally fatal (Bilodeau A, Prasil P, Cloutier R, et al, Hereditary multiple intestinal atresia: thirty years later. J Pediatr Surg 2004;39:726-730; Moreno LA, Gottrand F, Turck D, et al, Severe combined immunodeficiency syndrome associated with autosomal recessive familial multiple gastrointestinal atresias: study of a family. Am J Med Genet 1990;37:143-146). Patients have significant intestinal dysfunction and unrelenting sepsis stemming from a poorly defined, severe immunologic defect. Our case report presents 2 full siblings to nonconsanguineous parents with pyloric atresia, multiple small bowel and colonic atresias, and severe immune dysfunction. Care was withdrawn within 3 months of life on both siblings after multiple bouts of sepsis. Data suggest that the immune defect may not be primary, but in fact be secondary to intestinal dysfunction. Although the subjects in this article ultimately had fatal outcomes, a comprehensive immunologic/physiologic picture is presented in hopes of furthering the understanding of this grave disease.
