Patient satisfaction and health-related quality of life after autologous tissue breast reconstruction: a prospective analysis of early postoperative outcomes.

For this study, the authors evaluated early psychosocial adjustments and health‐related quality‐of‐life changes after breast reconstruction.

Breast reconstruction after mastectomy for breast cancer

Just as there have been improvements in the early detection and treatment of breast cancer, there have also been improvements in the techniques used for breast reconstruction after mastectomy. There are many reconstructive methods available, using either autologous tissue or implants,[1][1] each

Acellular dermal matrices in abdominal wall reconstruction: a systematic review of the current evidence.

Background: Reconstruction of the anterior abdominal wall is a complex procedure that can be complicated by contamination, loss of domain, previous scarring or radiotherapy, and reduced availability of local tissues. With the introduction of acellular dermal matrices to clinical use, it was hoped that many of the problems associated with previous synthetic materials could be overcome. With their enhanced biocompatibility, acellular dermal matrices are believed to integrate with surrounding tissues while demonstrating resistance to infection, extrusion, erosion, and adhesion formation. Methods: The MEDLINE database was reviewed, including all publications as of December 31, 2011, using the search terms “dermal matrix” or “human dermis” or “porcine dermis” or “bovine dermis,” applying the limits “human” and “English language.” Prospective and retrospective clinical articles were identified. Results: A total of 40 eligible articles were identified and included in this review. Thirty-five of the studies were level IV; the remaining studies were level III. Acellular dermal matrix was used to reconstruct the abdominal wall in a wide range of clinical settings, including trauma, tumor resection, sepsis, and hernia repairs. The operative methods varied widely among clinical studies. While the heterogeneity of the patient populations and techniques limited interpretation of the data, concerns were identified regarding high rates of hernia recurrence with acellular dermal matrix use. Conclusion: High-quality data derived from level I, II, and III studies are necessary to determine the indications for acellular dermal matrix use and the optimal surgical techniques to maximize outcomes in abdominal wall reconstruction. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, IV.

Barriers to Immediate Breast Reconstruction in the Canadian Universal Health Care System

PURPOSE To describe the population-based rates of immediate breast reconstruction (IBR) for all women undergoing mastectomy for treatment or prophylaxis of breast cancer in the past decade, and to evaluate geographic, institutional, and patient factors that influence use in the publically funded Canadian health care system. METHODS This population-based retrospective cohort study used administrative data that included 28,176 women who underwent mastectomy (25,141 mastectomy alone and 3,035 IBR) between April 1, 2002, and March 31, 2012, in Ontario, Canada. We evaluated factors associated with IBR by using a multivariable logistic regression model with the generalized estimating equation approach. RESULTS The population-based, age-adjusted IBR rate increased from 5.1 procedures to 8.7 in 100,000 adult women (43.7%; P < .001), and the increase was greatest for prophylactic mastectomy or therapeutic mastectomy for in situ breast cancer (78.6%; P < .001). Women who lived in neighborhoods with higher median income had significantly increased odds of IBR compared with mastectomy alone (odds ratio [OR], 1.71; 95% CI, 1.47 to 2.00), and immigrant women had significantly lower odds (OR, 0.59; 95% CI, 0.44 to 0.78). A patient had nearly twice the odds of receiving IBR when she was treated at a teaching hospital (OR, 1.84; 95% CI, 1.1 to 3.06) or at a hospital with two or more available plastic surgeons (OR, 2.01; 95% CI, 1.53 to 2.65). Patients who received IBR traveled significantly farther compared with those who received mastectomy alone (OR, 1.04; 95% CI, 1.02 to 1.05 for every 10 km increase). CONCLUSION IBR is available to select patients with favorable clinical and demographic characteristics who travel farther to undergo surgery at teaching hospitals with two or more available plastic surgeons.

Decision regret following breast reconstruction: the role of self-efficacy and satisfaction with information in the preoperative period.

Background: The relationship between satisfaction with information and decision regret has not been previously studied in breast reconstruction patients. The objective of this study, therefore, was to assess this relationship and the factors that may influence satisfaction with preoperative information, including self-efficacy (confidence with seeking medical knowledge). Methods: All patients who underwent breast reconstruction between January of 2009 and March of 2011 were approached to complete the Modified Stanford Self-Efficacy Scale (1 to 10), the satisfaction with information subscale of the BREAST-Q (1 to 100), and the Decision Regret Scale (1 to 100). Two multinomial logistic regression models were built to assess the relationship between patient-reported satisfaction with information and decision regret, and to evaluate the relationship among satisfaction with information, self-efficacy level, and sociodemographic characteristics. Results: In 100 participants (71 percent response rate), the mean Decision Regret Scale score was 9.3 ± 17.3 of 100, and the majority of patients experienced no regret (60 percent). We found that regret was significantly reduced when patients were more satisfied with the preoperative information that they received from their plastic surgeons (&bgr; = 0.95; 95 percent CI, 0.93 to 0.96). Furthermore, patients reported higher satisfaction with information when they possessed more self-efficacy irrespective of their sociodemographic characteristics (&bgr; = 1.06; 95 percent CI, 1.04 to 1.09). Conclusions: Patients who possess lower levels of self-efficacy are at greater risk for experiencing dissatisfaction with the information that they receive in the preoperative period, and ultimately suffered more regret over their decision to undergo breast reconstruction. CLINICAL QUESTION/LEVEL OF EVIDENCE: Risk, IV.

Improving outcomes in microsurgical breast reconstruction: Lessons learnt from 406 consecutive DIEP/TRAM flaps performed by a single surgeon

BACKGROUND Multiple preoperative, intraoperative and postoperative decisions can influence the outcome of microsurgical breast reconstruction. We have simplified the decision-making process by incorporating a number of algorithms into our microsurgical breast reconstruction practice and critically review our results in this study. METHODS Prospectively maintained databases for all microsurgical breast reconstructions performed by a single surgeon over a nine-year period were examined to determine: patient demographics; operative details including flap choice, donor and recipient vessel selection; and, details of intraoperative and early postoperative (<six weeks) complications and their management. RESULTS 406 Consecutive free flap microsurgical breast reconstructions (164 unilateral and 121 bilateral) were performed in 285 patients over the study period. Deep inferior epigastric artery perforator (DIEP) flaps (88%, n=359) were used most commonly followed by muscle-sparing transverse rectus abdominis musculocutaneous (MS-TRAM) flaps (11%, n=44), and fascial-sparing TRAM (FS-TRAM) flaps (0.7%, n=3). One-hundred-seventy-one (48%) DIEP flaps were based on a single perforator while 188 (52%) had multiple perforators. The internal mammary (IM) artery and vein were used as the recipient vessels for 99% (n=403) of flaps. A second venous anastomosis was required for 11.8 percent (n=48) of flaps. Partial flap failure occurred in nine (2.2%) flaps while total flap failure occurred in two flaps (0.5%). Minimum follow-up was three months. CONCLUSIONS Incorporating a number of algorithms into our practice has enabled us to simplify the decision-making processes involved in microsurgical breast reconstruction and to consistently obtain successful surgical outcomes.

A Comparison of Psychological Response, Body Image, Sexuality, and Quality of Life between Immediate and Delayed Autologous Tissue Breast Reconstruction: A Prospective Long-term Outcome Study

Background: This is the first study to use generic distress, cancer-specific, and procedure-specific measures to prospectively evaluate psychological responses, body image, sexuality, and health-related quality of life in immediate compared with delayed breast reconstruction. Methods: Consecutive patients undergoing autologous immediate and delayed breast reconstruction (June of 2009 to December of 2010) completed the Hospital Anxiety and Depression Scale, Body Image Scale, Sexuality Scale, and BREAST-Q preoperatively and postoperatively (6, 12, and 18 months). Linear mixed-effects analyses between each outcome and time point were performed. Results: One hundred six women underwent mastectomy with immediate (n = 30) and delayed breast reconstruction (n = 76). Before reconstruction, 26 percent of patients had abnormal anxiety scores and 9 percent had abnormal depression scores, with no significant differences between groups. Patients awaiting delayed breast reconstruction had significantly impaired prereconstruction body image (p = 0.01) and sexuality (p = 0.01) and worse satisfaction with breast (p < 0.01), psychological (p < 0.01), and sexual well-being (p < 0.01). At 18 months after immediate and delayed breast reconstruction, there was significant improvement in anxiety, depression, body image, sexuality, and health-related quality of life. Conclusions: This single-center study shows that mastectomy with immediate breast reconstruction may protect breast cancer patients from a period of psychosocial distress, poor body image, and diminished sexual well-being compared with those waiting for delayed breast reconstruction. In patients who are oncologically eligible and strongly interested in breast reconstruction, efforts should be made to provide immediate breast reconstruction to decrease the interval of psychosocial distress, poor body image, and impaired sexuality.

Transversus abdominis plane (TAP) catheters inserted under direct vision in the donor site following free DIEP and MS-TRAM breast reconstruction: A prospective cohort study of 45 patients

INTRODUCTION The transversus abdominis plane (TAP) block is a peripheral nerve block of T6-L1 intercostal nerves of the abdominal wall. The purpose of this study was to evaluate the usefulness of intermittent TAP blockade for the first two postoperative days following free muscle sparing-transverse rectus abdominis muscle (MS-TRAM) or deep inferior epigastric perforator (DIEP) flap reconstruction of the breast. Therapeutic--Level II evidence. MATERIAL AND METHODS This prospective cohort consisted of 45 consecutive patients who underwent DIEP or MS-TRAM free-flap breast reconstruction. Intra-operatively, a multi-orifice epidural catheter was inserted under direct vision into the TAP. Ten millilitres of 0.25% bupivacaine was injected into each TAP catheter every 12 h until removal on day 3. The control group consisted of 80 consecutive patients who underwent free MS-TRAM or DIEP free-flap breast reconstructions by the same two surgeons without TAP block. Postoperatively, both groups had patient-controlled analgesia (PCA) and the primary outcome was intravenous (IV) PCA opioid consumption in the first 48 h. RESULTS There were no complications associated with using TAP catheters. The 48-h PCA-delivered opioid requirement was significantly less (p<0.001) in the TAP block group (17.10±17.23 mg IV morphine equivalent) compared to the control group (48.44±39.53 mg). CONCLUSION Intermittent delivery of bupivacaine through the TAP block significantly reduced postoperative parenteral opioid requirements following free MS-TRAM or DIEP flap reconstruction of the breast. This is the first report of the TAP block being inserted under direct vision to provide postoperative analgesia at the abdominal flap donor site following microsurgical breast reconstruction.

Tug 'O' war: challenges of transverse upper gracilis (TUG) myocutaneous free flap breast reconstruction.

Autologous tissue microsurgical breast reconstruction is increasingly requested by women following mastectomy. While the abdomen is the most frequently used donor site, not all women have enough abdominal tissue excess for a unilateral or bilateral breast reconstruction. A secondary choice in such women may be the transverse upper gracilis (TUG) myocutaneous flap. This study reviews our experience with TUG flap breast reconstruction looking specifically at reconstructive success rate and the requirement for secondary surgery. A total of 16 free TUG flaps were performed to reconstruct 15 breasts in eight patients over a period of five years. Data were collected retrospectively by chart review. Follow up ranged from 14 to 41 months. During the follow up period, there was one (6.3%) complete flap loss in an immediate breast reconstruction patient. Four further flaps (25%) failed in their primary aim of breast reconstruction, as they required additional significant reconstruction with either deep inferior epigastric perforator (DIEP) flaps (two flaps (12.5%), one patient) or augmentation with silicone breast implants (two flaps (12.5%), one patient), giving a successful breast reconstruction rate with the TUG flap of only 66.7%. In all of the remaining reconstructed breasts, deficient flap volume or breast contour was seen. Eight flaps were augmented by lipofilling. A total of 62.5% of the donor sites had complications, namely sensory disturbance of the medial thigh (25%) and poor scar (37.5%) requiring revision. This series demonstrates a high rate of reconstructive failure and unsatisfactory outcomes from TUG flap breast reconstruction. We feel this reinforces the necessity of adequate pre-operative patient assessment and counselling, including discussion regarding the likelihood of subsequent revisional surgery, before embarking on this form of autologous breast reconstruction.

Reconstruction of sarcoma defects following pre-operative radiation: Free tissue transfer is safe and reliable

BACKGROUND Neoadjuvant radiotherapy followed by surgical resection and soft tissue reconstruction provides the best possibility of achieving superior limb function in soft tissue sarcomas. The aim of this study was to report our experience of free flap microsurgical reconstruction of recently irradiated soft tissue sarcoma defects. METHODS A retrospective study of microsurgical outcome in consecutively treated extremity and trunk sarcoma patients undergoing free tissue transfer between 2007 and 2012 was conducted from a prospectively collected database. Outcomes in pre-operatively irradiated patients were compared with non-irradiated patients. Demographic data, operative details, limb salvage rate, post-operative including microsurgical complications, and long-term limb function (Toronto Extremity Salvage score, TESS; Musculoskeletal Tumour Society Rating Scale, MSTS) were recorded and analysed for differences between the two study groups. RESULTS Forty-six patients underwent 46 free flaps (pre-irradiated n = 32, non-irradiated n = 14) over the study period. Microvascular complications (intra-operative revision, flap re-exploration, flap loss) were uncommon and similar between the two groups (4/32 and 2/14 respectively, p > 0.05). Recipient site wound healing complications (i.e. not flap related) occurred more frequently in pre-irradiated patients (16 events) compared with the control group (2 events, p = 0.03). There was no significant difference in limb salvage rate, or TESS/MSTS functional outcome scores between the two patient groups. CONCLUSIONS Free tissue transfer is safe and effective in patients undergoing surgical resection and reconstruction following neoadjuvant radiotherapy.
