RESUMO
We previously developed and validated a vortexing-sonication technique for detection of biofilm bacteria on the surface of explanted prosthetic joints. Herein, we evaluated this technique for diagnosis of infected breast tissue expanders and used it to assess colonization of breast tissue expanders. From April 2008 to December 2011, we studied 328 breast tissue expanders at Mayo Clinic, Rochester, MN, USA. Of seven clinically infected breast tissue expanders, six (85.7%) had positive cultures, one of which grew Propionibacterium species. Fifty-two of 321 breast tissue expanders (16.2%, 95% CI, 12.3-20.7%) without clinical evidence of infection also had positive cultures, 45 growing Propionibacterium species and ten coagulase-negative staphylococci. While vortexing-sonication can detect clinically infected breast tissue expanders, 16 percent of breast tissue expanders appear to be asymptomatically colonized with normal skin flora, most commonly, Propionibacterium species.

PURPOSE: There is controversy about performing reduction mammaplasty in younger patients. Although no studies show poor surgical outcomes, a paucity of data exists on long-term outcomes and satisfaction. METHODS: A single center mixed-mode mail and telephone surveyed 203 women who underwent reduction mammaplasty for symptomatic macromastia between 1985 and 2005, who were <21 years of age at surgery. A total of 99 women responded (48.8%). RESULTS: Mean operative patient age was 19.1 years (range, 16.2-20.9 years). Mean follow-up was 15.6 years (range, 6.0-26.4 years). Sustained long-term symptom resolution was highest with shoulder pain (94.7%), breast pain (92.0%), and intertrigo (88.6%). Improvements in feeling uncomfortable (87.5%), finding clothes that fit (86.0%), sports participation (85.2%), and running (83.7%) were reported. Patients reported self-perceived decreased nipple sensitivity (67.2%) and difficulties breast-feeding (65.2%). Prominent incisional scarring was reported by 71.7%; however, 56.5% reported that scarring had not affected them in any way. The majority (93.9%) rated the overall success of their operation as at least 50% successful; 42.4% reported 100% success in treating the problems. Improved quality of life was reported by 88.7%. Most respondents (66.7%) would definitely recommend this procedure to a friend or family member at the same age. Knowing what they know now, 95.9% would choose to have the surgery again. Subgroup analysis of patients <18 years of age (n = 23; mean age, 17.3 years) at the time of surgery revealed equivalent results. CONCLUSIONS: Long-term follow-up of reduction mammaplasty in patients aged 16-20 years shows good overall satisfaction and improvements in quality of life.

BACKGROUND: Since 1997, the authors have used a minimally invasive technique for the management of gynecomastia using ultrasound-assisted liposuction and the arthroscopic shaver to remove breast tissue through a remote incision. This technique has allowed for a consistent, refined, "unoperated" postoperative appearance in this patient population. This study analyzes the outcomes of this procedure and compares the procedure against established techniques. METHODS: A retrospective study was performed on all patients who underwent surgery for gynecomastia at the authors' institution between January of 1988 and October of 2007. A total of 227 patients were divided into four groups: group 1, open excision only (n = 45); group 2, open excision plus liposuction (n = 56); group 3, liposuction only (n = 50); and group 4, liposuction plus arthroscopic shaver (n = 76). Medical records and photographs were used to compare groups for complications and results. RESULTS: Complications using the liposuction plus arthroscopic shaver technique included seroma (n = 2), hematoma (n = 1), scar revision (n = 1), and skin buttonhole from the arthroscopic shaver (n = 1). There was no difference between groups in the overall incidence of complications (p < 0.20) or the need for reoperation (p < 0.325). Results were scored on a scale of 1 (poor) to 5 (excellent). Group 4 (liposuction plus arthroscopic shaver) had the overall highest mean score, with statistical significance between group 2 (open excision plus liposuction) and group 4 (p < 0.0001). CONCLUSION: Arthroscopic mastectomy for gynecomastia is a safe and effective technique, with excellent cosmetic results and an acceptable complication rate.

BACKGROUND: External hemipelvectomy is the ultimate salvage procedure for locally advanced pelvic tumors, infections, and failed revascularizations. It is associated with high wound morbidity requiring surgical management. In this study, the authors analyzed their experience with primary and secondary reconstruction of hemipelvectomy wounds. METHODS: The records of 160 consecutive hemipelvectomy patients from the authors' institution were reviewed to identify the incidence of soft-tissue coverage problems and approaches to their management. RESULTS: At the time of hemipelvectomy, a musculocutaneous hemipelvectomy flap was sufficient for closure in 159 patients, one patient needed a free lower leg fillet flap, and none required pedicle flaps. No hemipelvectomy hernias were observed, although abdominal wall reconstruction was performed in three patients. Wound complications were encountered in 62 patients (39 percent), and 51 patients required operative débridement. Thirty-three patients healed by secondary intention, and 25 underwent delayed reconstruction with local tissue rearrangements (n = 15), split-thickness skin grafting (n = 6), and pedicled flaps (n = 6). All pedicled flaps were contralateral inferiorly based rectus abdominis muscle (n = 2) and musculocutaneous (n = 4) flaps. CONCLUSIONS: Hemipelvectomy is associated with high wound morbidity. When the hemipelvectomy flap has a musculocutaneous design, hernias are exceedingly rare. Although immediate reconstruction is accomplished with a hemipelvectomy flap in the vast majority of cases, secondary reconstructions are often required for management of wound complications. For large defects, a contralateral inferiorly based rectus abdominis muscle or musculocutaneous flap is the reconstruction of choice. The rectus abdominis muscle should therefore always be preserved in hemipelvectomy patients by careful preoperative planning, especially when creation of an ostomy is considered.

Capsular contracture is the most common and frustrating complication in women who have undergone breast implantation. Its cause and, accordingly, treatment and prevention remain to be elucidated fully. The aim of this prospective observational pilot study was to test the hypothesis that the presence of bacteria on breast implants is associated with capsular contracture. We prospectively studied consecutive patients who underwent breast implant removal for reasons other than overt infection at the Mayo Clinic from February through September 2008. Removed breast implants were processed using a vortexing/sonication procedure and then subjected to semiquantitative culture. Twenty-seven of the 45 implants collected were removed due to significant capsular contracture, among which 9 (33%) had >or=20 CFU bacteria/10 ml sonicate fluid; 18 were removed for reasons other than significant capsular contracture, among which 1 (5%) had >or=20 CFU/10 ml sonicate fluid (P = 0.034). Propionibacterium species, coagulase-negative staphylococci, and Corynebacterium species were the microorganisms isolated. The results of this study demonstrate that there is a significant association between capsular contracture and the presence of bacteria on the implant. The role of these bacteria in the pathogenesis of capsular contracture deserves further study.

BACKGROUND: Hemipelvectomy has high wound complication rates. This study aimed to determine variables that may influence hemipelvectomy wound morbidity. METHODS: The records of 160 consecutive hemipelvectomy patients were reviewed with a focus on demographics, treatment, and surgical techniques. Multivariate analysis was used to determine risk factors for postoperative hemipelvectomy wound infection and flap necrosis. RESULTS: There were 31 standard, 62 modified, and 67 extended hemipelvectomy patients in whom 19 contiguous visceral, 62 spinal, 4 contralateral pelvic resections, and 1 contralateral hemipelvectomy were performed. Hospital mortality rate was 5%, and overall morbidity was 54%. Wound complications such as infection (39%) and flap necrosis (26%) were the most common. For modified, standard, and extended hemipelvectomies, rates of wound infection were 29%, 34%, and 51% (P = .036) and rates of flap necrosis were 16%, 25%, and 35% (P = .046), respectively. Longer operative time and increased complexity were associated with higher wound infection and flap necrosis rates. The hemipelvectomy flap design did not influence the frequency of wound infection (P = .173) or flap necrosis (P = .098). Common iliac vessel ligation was the most statistically significant predictor of flap necrosis and was associated with the 2.7-fold increase in flap necrosis rate (P = .001) in patients undergoing posterior flap hemipelvectomy. CONCLUSIONS: External hemipelvectomy has low mortality but high morbidity. Postoperative wound infection and flap necrosis are multifactorial events related to length and extent of operation. Level of vascular ligation strongly influenced flap necrosis rate for posterior flap hemipelvectomy.

BACKGROUND: Flaps are currently the predominant method of reconstruction for irradiated wounds. The usefulness of split-thickness skin grafts (STSG) in this setting remains controversial. The purpose of this study is to examine the outcomes of STSGs in conjunction with VAC therapy used in the treatment of irradiated extremity wounds. METHODS: The records of 17 preoperatively radiated patients with extremity sarcomas reconstructed with STSGs in conjunction with VAC(R) therapy were reviewed regarding details of radiation treatment, wound closure, and outcomes. RESULTS: STSGs healed without complications (>95% of the graft take) in 12 (71%). Minor loss (6% - 20% surface) was noted in 3 patients (17.6%) and complete loss in 2 (11.7%). Two patients (11.7%) required flap reconstructions and 12 (88%) healed without further operative procedures. CONCLUSION: Although flap coverage is an established treatment for radiated wounds, STSG in conjunction with liberal utilization of VAC therapy is an alternative for selected patients where acceptable soft tissue bed is preserved. Healing of the preoperatively radiated wounds can be achieved in the vast majority of such patients with minimal need for additional reconstructive operations.
RESUMO
PURPOSE: Contralateral prophylactic mastectomy (CPM) is one option for reducing the risk of a second breast cancer in women with a personal and family history of breast cancer. Few data are available regarding satisfaction, psychological, and social function after CPM. The purpose of this research is to evaluate women's long-term satisfaction with CPM, factors influencing satisfaction, and psychological and social function after CPM. PATIENTS AND METHODS: This was a descriptive study of all women with a family history of breast cancer, known to be alive, who elected CPM at Mayo Clinic (Rochester, MN) between 1960 and 1993 (n = 621). Ninety-four percent of the women (n = 583) completed a study-specific questionnaire. RESULTS: A mean of 10.3 years after the procedure, the majority of women (83%) were satisfied with their CPM. A smaller number were neutral (8%) or dissatisfied (9%). Women who had a subcutaneous mastectomy had more problems with reconstruction, and fewer of these women were satisfied than women with simple mastectomy. Decreased satisfaction with CPM was associated with decreased satisfaction with appearance, complications with reconstruction, reconstruction after CPM, and increased level of stress in life. The majority of women experienced no change or favorable effects in self-esteem (83%), level of stress in life (83%), and emotional stability (88%). Satisfaction with body appearance, feelings of femininity, and sexual relationships were the most adversely affected with 33%, 26%, and 23% of the women responding negatively. CONCLUSION: Although most women are satisfied with CPM, each woman should weigh the benefits alongside the potential adverse effects.

This study compares the outcome of Singapore flap, vertical rectus abdominis musculocutaneous flap (VRAM), and gracilis musculocutaneous flap vaginal reconstruction. A retrospective review of 99 consecutive patients with complete vaginal defects was conducted at the Mayo Clinic from January 1988 to October 2001. All possible complications were determined for each of the 3 reconstructive techniques, along with the effects of radiation and smoking on the respective complication rates. Preoperative and postoperative sexual function and adequacy were compared between each group. Ninety-nine patients ranging in age from 19 to 80 years (mean, 51.6 years) were compared, with a mean follow-up of 28.9 months. Forty-one VRAM, 13 gracilis, and 45 modified Singapore flaps were used for vaginal reconstruction. The majority was due to acquired vaginal defects due to recurrent pelvic malignancy. The overall complication rate was lower following VRAM than either gracilis or Singapore flap reconstructions (13/41, 31.7%; 8/13, 61.5%; and 21/45, 46.7%, respectively). The flap specific complication rate was least in the VRAM group (9/41, 22%; 7/13, 53.8%; and 17/45, 37.8%, respectively). The VRAM had a significant protective effect against the development of postoperative small bowel obstruction. Preoperative sexual activity predicted postoperative activity in 75 of 88 patients (85.2%) and was not affected by the type of reconstruction, although more patients with a Singapore flap required vaginal dilatation to maintain patency. In conclusion, the VRAM has a lower overall and flap-related complication rate compared with either gracilis or Singapore flap reconstruction. It has become our vaginal reconstructive flap of choice.

BACKGROUND: The authors characterized the unanticipated reoperations after prophylactic mastectomy, with or without implant reconstruction. METHODS: The surgical cohort was comprised of 1417 women with a family history of breast carcinoma. The women received a prophylactic mastectomy with (bilateral, n = 593; contralateral, n = 506) or without reconstruction (n = 318) at the Mayo Clinic (Rochester, MN) between 1960 and 1993. Reoperations and indications for reoperation were compiled from medical records and a patient survey. RESULTS: Three hundred eighteen women received a bilateral (n = 39) or contralateral (n = 279) prophylactic mastectomy without reconstruction. With a median follow-up of 15 years, 18 women (6%) required reoperation. Most of these reoperations occurred within the first year after prophylactic mastectomy. Five hundred ninety-three women had reconstruction with implants following bilateral prophylactic mastectomy. Approximately one-half of the women (52%) required at least 1 unanticipated reoperation during a median follow-up of 14 years. Approximately 39% of all reoperations occurred within 1 year of breast reconstruction and 69% within 5 years. Implant-related issues were the most common cause for reoperation. Some women with breast carcinoma elected to receive contralateral prophylactic mastectomy with therapeutic mastectomy for the affected breast. Five hundred six women received reconstruction with implants. During a median follow-up of 8.8 years, 189 women (37%) required unanticipated reoperation. The most common indication was implant-related issues. The time course of reoperations was similar to that for women in the bilateral group. CONCLUSIONS: Surgical reoperations were fairly common among women who received prophylactic mastectomy with implant reconstruction. Most of the reoperations were implant related. Reoperations were fairly uncommon after prophylactic mastectomy without reconstruction.
