Reducing donor-site complications in DIEP flap breast reconstruction with closed incisional negative pressure therapy: A cost-benefit analysis.

INTRODUCTION: Deep inferior epigastric perforator (DIEP) flaps are considered the gold standard for autologous breast reconstruction but create large abdominal incisions that risk donor-site morbidity during harvest. Closed incision negative pressure therapy (ciNPT) is emerging as an effective alternative to standard postoperative dressings, but there is a paucity of data in DIEP flap donor sites. METHODS: We conducted a retrospective case-control study investigating the use of ciNPT in DIEP flap donor sites at a single institution between March 2017 and September 2021. Patients who underwent microsurgical autologous breast reconstruction with DIEP flaps were included. Patients were divided into those with donor incision sites managed with ciNPT (n = 24) and those with conventional postoperative wound dressings (n = 20). We compared patient demographics, wound drainage volumes and postoperative outcomes between the two groups. A cost-benefit analysis was employed to compare the overall costs associated with each complication and differences in length of stay between the two groups. RESULTS: There was no statistically significant difference in age, body mass index (BMI), comorbidity burden or smoking status between the two groups. Both groups had similar lengths of stay and wound drainage volumes with no readmissions or reoperations in either group. There was a statistically significant reduction in donor-site complications (p = 0.018), surgical site infections (p = 0.014) and seroma formation (p = 0.016) in those with ciNPT. Upon cost-benefit analysis, the ciNPT group had a mean reduction in cost-per-patient associated with postoperative complications of £420.77 (p = 0.031) and £446.47 (p = 0.049) when also accounting for postoperative length of stay CONCLUSION: ciNPT appears to be an effective alternative incision management system with the potential to improve complication rates and postoperative morbidity in DIEP flap donor sites. Our analysis demonstrates improved cost-benefit outweighing the increase in costs associated with ciNPT. We recommend a multicentre prospective trial with formal cost-utility analysis to strengthen these findings.

UK Guidelines for Lipomodelling of the Breast on behalf of Plastic, Reconstructive and Aesthetic Surgery and Association of Breast Surgery Expert Advisory Group.

Lipomodelling has become increasingly popular for reconstructive, aesthetic and therapeutic indications. The guidelines summarise available evidence for indications, training, technique, audit and outcomes in lipomodelling and also highlight areas for further research.

Revision Surgery to Improve Cosmesis with Immediate Implant-Based Breast Reconstruction.

BACKGROUND: Following mastectomy for breast cancer, patients may be presented with a range of reconstructive options. The most popular being immediate implant-based reconstruction (IBR). OBJECTIVE: To determine the rate of revision surgery to improve cosmesis following IBR. DESIGN: Retrospective cohort study. SETTING/PATIENTS: All patients who underwent IBR at a single UK-based specialist breast reconstructive centre between June 2012 and June 2013. MEASUREMENTS: The authors collected data, including demographics, original surgery, revision surgeries and factors likely to influence the cosmetic result. RESULTS: A total of 88 procedures were included in the study and follow up was performed for a mean duration of 1125 days. In all, 39 breasts required further revision to improve cosmesis to undergo a total of 53 additional procedures. Lipomodelling was the most frequently performed revision (n = 18), whilst implant exchange (n = 16), implant removal (n = 11) and other minor revisions (n = 8) made up the remainder. An early (<3 months) complication, adjuvant radiotherapy and capsular contracture significantly increased the chance of revision surgery (p = 0.018, p = 0.04 and p = 0.009, respectively). Revision surgery added an additional monetary cost of 27.1%-74.1%, which depends on the original procedure performed. LIMITATIONS: The risk of further revision surgery is likely to be higher in those who are followed up for longer periods. CONCLUSIONS: Following immediate IBR, revision surgery represents a substantial burden to the patient including healthcare costs.

Radioactive seed localization compared with wire-guided localization of non-palpable breast carcinoma in breast conservation surgery- the first experience in the United Kingdom.

OBJECTIVE: In the UK, guidewires have traditionally been used for localization of non-palpable breast lesions in patients undergoing breast conservation surgery (BCS). Radioactive seed localization (RSL) using Iodine-125 seeds is an alternative localization method and involves inserting a titanium capsule, containing radioactive Iodine-125, into the breast lesion. We aim to demonstrate feasibility of RSL compared with guidewire-localization (GWL) for BCS in the UK. METHODS: Data were collected on 100 patients with non-palpable unifocal invasive carcinoma of the breast undergoing GWL WLE prior to the introduction of RSL and the first 100 patients treated with RSL WLE. Statistical comparisons were made using Χ2-squared analysis or unpaired two-sample t-test. Significance was determined to be at p ≤ 0.05. RESULTS: Mean total tumour size was 19.44 mm (range: 5-55) in the GWL group and 18.61 mm (range: 3.8-59) in the RSL group (p = 0.548), while mean total specimen excision weight was significantly lower in the RSL group; 31.55 g (range: 4.5-112) vs 37.42 g (range: 7.8-157.1) (p = 0.018). Although 15 patients had inadequate surgical resection margins in the GWL group compared the 13 in the RSL group (15 vs 13%, respectively, p = 0.684), 10 of the patients in the GWL group had invasive carcinoma present resulting in at least one positive margin compared with only 3 patients in the RSL group (10 vs 3%, respectively, p = 0.045). CONCLUSION: In this study, RSL is shown to be non-inferior to the use of GWL for non-palpable carcinoma in patients undergoing BCS and we suggest that it could be introduced successfully in other breast units. Advances in knowledge: Here we have demonstrated the use of RSL localization results in significant lower weight resection specimens of breast carcinoma when compared with a matched group using GWL, without any significant differences in oncological outcome between the groups.

The introduction of radioactive seed localisation improves the oncological outcome of image guided breast conservation surgery.

INTRODUCTION: Radioactive seed localisation (RSL) has become increasingly popular for localisation of non-palpable breast tumours. This is largely due to advantages it offers in terms of practicality and convenience when compared to guide wire localisation (WL). This institute switched from using WL to RSL in September 2014. The primary aim was to assess whether this change improved the accuracy of excision with regards to inadequate margin rates and weight of excision specimens. The secondary aim was to establish whether there is a "learning curve" associated with RSL technique. METHODS: Retrospective data collection was performed for 333 consecutive cases of unifocal non-palpable invasive breast cancers undergoing excision with WL or RSL. An inadequate margin was defined as tumour <1 mm from an inked radial margin. Patient demographics, tumour characteristics and clinical outcomes were compared between WL and RSL cases. RESULTS: 100 WL and 233 RSL cases were included. Patient demographics and tumour characteristics were similar for both groups. Inadequate margin rates were 18% with WL and 8.6% with RSL (p = 0.013). Median specimen weights were 33.3 g with WL and 28.7 g with RSL (p = 0.014). Subdividing the RSL group into the first 100 cases performed (RSL1) and the subsequent 133 cases (RSL2), inadequate margin rates were 13.0% and 5.3% respectively (p = 0.037). Mean specimen weights were similar. CONCLUSION: Switching from WL to RSL results in a significant reduction in both inadequate margin rates and specimen weights. A procedure-specific learning curve is present on first implementation of RSL and following this, inadequate margin rates are further reduced.

Breast implant associated anaplastic large cell lymphoma: The UK experience. Recommendations on its management and implications for informed consent.

BACKGROUND: Breast implant-associated anaplastic large-cell lymphoma (BIA-ALCL) is a rare, Non-Hodgkin lymphoma arising in the capsule of breast implants. BIA-ALCL presents as a recurrent effusion and/or mass. Tumours exhibit CD30 expression and are negative for Anaplastic Lymphoma Kinase (ALK). We report the multi-disciplinary management of the UK series and how the stage of disease may be used to stratify treatment. METHODS: Between 2012 and 2016, 23 cases of BIA-ALCL were diagnosed in 15 regional centres throughout the UK. Data on breast implant surgeries, clinical features, treatment and follow-up were available for 18 patients. RESULTS: The mean lead-time from initial implant insertion to diagnosis was 10 years (range: 3-16). All cases were observed in patients with textured breast implants or expanders. Fifteen patients with breast implants presented with stage I disease (capsule confined), and were treated with implant removal and capsulectomy. One patient received adjuvant chest-wall radiotherapy. Three patients presented with extra-capsular masses (stage IIA). In addition to explantation, capsulectomy and excision of the mass, all patients received neo-/adjuvant chemotherapy with CHOP as first line. One patient progressed on CHOP but achieved pathological complete response (pCR) with Brentuximab Vedotin. After a mean follow-up of 23 months (range: 1-56) all patients reported here remain disease-free. DISCUSSION: BIA-ALCL is a rare neoplasm with a good prognosis. Our data support the recommendation that stage I disease be managed with surgery alone. Adjuvant chemotherapy may be required for more invasive disease and our experience has shown the efficacy of Brentuximab as a second line treatment.

Reducing implant loss rates in immediate breast reconstructions.

UK best practice guidelines for oncoplastic breast reconstruction were published in 2012. Implant-based reconstruction quality indicator (QI) targets for readmission, return to theatre and implant loss rates were set at 5% by 3 months, along with guidance to achieve these targets. The aims of this study were to quantify complication rates following implant-based reconstruction before and after the implementation of the guidelines. A retrospective audit of 86 patients with 106 implants in the 12 months to June 2013 was performed, C1. Following institutional changes including reducing antibiotic usage, a prospective audit was performed on 89 patients with 105 implants to June 2014, C2. Extended follow-up of salvaged implants was also performed. Demographics were not significantly different between the two cohorts apart from smoking. Implant loss rates fell from 7.5%(C1) to 1.9%(C2), p = 0.054 but at the cost of an increase in the return to theatre rate (14.2%-18%, p > 0.05). The implant salvage rate increased from 47% in C1 to 89.5% in C2, however, 3 of the implants that were salvaged were lost in the long term giving an overall salvage rate of 82.4% in C2. While an implant loss rate of <5% at 3 months appears achievable with less antibiotic use, this was made possible by the institution of an aggressive readmission and salvage policy. We would question the QI standards for readmission and return to theatre for immediate implant-based breast reconstruction, given that our implant loss rate of 1.9% was achieved with a return to theatre rate of 18%.

National trends in immediate and delayed post-mastectomy reconstruction procedures in England: A seven-year population-based cohort study.

INTRODUCTION: Little is known about post-mastectomy reconstruction procedural trends in women diagnosed with breast cancer in England. Our aim was to examine patterns of immediate and delayed reconstruction procedures over time and within regions. METHODS: Women with breast cancer who underwent unilateral index immediate or delayed post-mastectomy reconstruction between 2007 and 2014 were identified using the National Hospital Episode Statistics database. Women were grouped into categories based on the type of reconstruction procedure. Adjusted rates of implant and free flap reconstructions were then calculated across regional Cancer Networks using a regression model to adjust for age, disease, comorbidities, ethnicity, and deprivation. RESULTS: Between 2007 and 2014, 21 862 women underwent immediate reconstruction and 8653 delayed reconstruction. Immediate implant reconstruction increased from 30% to 54%, and immediate free flap reconstruction from 17% to 21%. Adjusted immediate implant and free flap proportions ranged from 17 to 68% and 9-63%, respectively, across regions. Free flaps became more common in the delayed setting, rising from 25% to 42%. However, adjusted rates ranged from 23% to 74% across regions. Networks with high/low rates of free flaps for immediate tended to have high/low rates for delayed reconstruction. CONCLUSION: There has been a substantial increase in the use of immediate implant reconstruction in England. In comparison, there has been an increasing use of autologous free flap reconstruction for delayed procedures. Significant regional variation exists in the type of reconstruction performed, and these patterns need to be examined to determine if variation is related to service provision and/or capacity barriers.

National trends and regional variation in immediate breast reconstruction rates.

BACKGROUND: Previous studies have identified variation in immediate reconstruction (IR) rates following mastectomy for breast cancer across English regions during a period of service reorganization, a national audit and changing guidelines. This study analysed current variations in regional rates of IR in England. METHODS: Patient-level data from Hospital Episode Statistics were used to define a cohort of women who underwent primary mastectomy for invasive or in situ breast carcinoma in English National Health Service (NHS) hospitals between April 2000 and March 2014. A time series of IR rates was calculated nationally and within regions in 28 cancer networks. Regional IR rates before and after the national audit were compared, using logistic regression to adjust for patient demographics, tumour type, co-morbidity and year of mastectomy. RESULTS: Between 2000 and 2014, a total of 167 343 women had a mastectomy. The national IR rate was stable at around 10 per cent until 2005; it then increased to 23·3 per cent by 2013-2014. Preaudit (before January 2008), adjusted cancer network-level IR rates ranged from 4·3 to 22·6 per cent. Postaudit (after April 2009) adjusted IR rates ranged from 13·1 to 36·7 per cent, with 20 networks having IR rates between 15 and 24 per cent. The degree of change was not greatest amongst those that started with the lowest IR rates, with four networks with the largest absolute increase also starting with relatively high IR rates. CONCLUSION: The national IR rate increased throughout the study period. Substantial regional variation remains, although considerable time has elapsed since a period of service reorganization, guideline revision and a national audit.

Acellular dermal matrix (ADM) assisted breast reconstruction procedures: joint guidelines from the Association of Breast Surgery and the British Association of Plastic, Reconstructive and Aesthetic Surgeons.

Tissue expansion with delayed insertion of a definitive prosthesis is the most common form of immediate breast reconstruction performed in the United Kingdom. However, achieving total muscle coverage of the implant and natural ptosis is a key technical challenge. The use of acellular dermal matrices (ADM) to supplement the pectoralis major muscle at the lower and lateral aspects of the breast has been widely adopted in the UK, potentially allowing for a single stage procedure. There is however little published data on the clinical and quality criteria for its use, and no long term follow-up. The guidelines have been jointly produced by the Association of Breast Surgery and the British Association of Plastic, Reconstructive and Aesthetic Surgeons and their aims are: to inform those wishing to undertake ADM assisted breast reconstruction and, to identify clinical standards and quality indicators for audit purposes. The guidelines are based on expert opinion of a multi-disciplinary working group, who are experienced in the technique, and a review of the published data.

Therapeutic mammaplasty--a systematic review of the evidence.

INTRODUCTION: Therapeutic mammaplasty (TM) is suggested to have a number of advantages by comparison to conventional breast conserving surgery (BCS), but there is a paucity of published data on TM which evaluates oncologic and aesthetic end-points, and outcomes remain uncertain. METHODS: Online databases were searched to identify studies regarding TM. Identified studies were scrutinised and key data relating to oncologic and aesthetic outcome, patient reported outcome measures (PROMs) and study design were recorded. RESULTS: Most identified studies were retrospective, and no randomised controlled trials were found. Mean tumour size was reported in nine of 20 studies, with only four of 20 reporting on mean surgical margins obtained at TM. Management of a positive surgical margin following TM varied considerably between studies. With a median follow-up of between 13 and 68 months, rates of local recurrence, metastasis and death were comparable to BCS. Aesthetic assessment was complete in only three of 15 studies. PROMs and aesthetic outcomes were evaluated using non-validated tools. All studies evaluating aesthetic outcome contained evaluation by clinicians, but included patient views in only 10/15 studies. Complication rates ranged between 10% (6/63) and 91% (28/31), but delayed adjuvant treatment in only 6% of cases. CONCLUSION: Identified studies fail to clarify indications or confirm the suggested improved outcomes from TM over BCS, although oncological outcomes appear comparable. High complication rates impact little on delivery of adjuvant therapies. Prospective data registration is required to define indications and quality assurances, and support development of specific assessment tools for this technique in the future.

Use of the ipsilateral breast in anterolateral chest wall reconstruction.

Chest wall ablative surgery often requires autologous tissue transfer to reconstruct the resulting defect. The female breast is commonly of a suitable size to provide anteromedial chest wall coverage as a pedicled dermoglandular flap. In anterolateral defects the latissimus dorsi or serratus anterior flaps are often the preferred choice, in the absence of which free tissue transfer is an alternative technique. However these options may not always be available or suitable. A 90-year-old female presented with a large chest wall mass in keeping with recurrence of oesophageal squamous cell carcinoma in the thoracotomy scar following a previous oesophagectomy. The latissimus dorsi and serratus anterior muscles were transected during the previous thoracotomy. Following complete resection, the ipsilateral breast was used as a rotational dermoglandular flap to provide coverage over the exposed ribs. The use of breast as a local flap is an alternative option in anterolateral chest wall reconstruction.

How to improve plastic surgery knowledge, skills and career interest in undergraduates in one day.

INTRODUCTION: Plastic surgery now occupies a negligible component of many undergraduate curricula. The British Association of Plastic, Reconstructive and Aesthetic Surgeons Undergraduate Course aimed to introduce and improve students' plastic surgery knowledge and skills, as well as develop personal career interests. This research aims to quantify whether this was achieved. METHODS: Students attending the one-day course were invited to complete a questionnaire before and after the course. Questions were self-reflective and incorporated four key themes: (1) plastic surgery knowledge; (2) awareness of the work of a plastic surgeon; (3) ability to perform basic plastic surgical skills; (4) career interest in plastic surgery. Non-medical students were given an identical questionnaire to quantify public perception of the work of a plastic surgeon. RESULTS: 121 students attended from 17 universities across the UK, with 93 completing the questionnaire (77% response rate). Paired analyses compared mean or median scores of the students' answers before and after the course. After completing the course, medical students significantly improved in all four key themes (p<0.01). 93 non-medical students completed questionnaires. Medical students were significantly more accurate at identifying plastic surgery procedures than non-medical students (P < 0.01), which was further strengthened after completing the course (P < 0.001). CONCLUSION: This study demonstrates the positive educational impact of a one-day plastic surgery event for medical students and supports the need for plastic surgery education at an undergraduate level.

Prospective evaluation of late cosmetic results following breast reconstruction: I. Implant reconstruction.

The long-term cosmetic outcome of breast implant reconstruction is unknown. The morbidity and cosmetic outcome of 360 patients who underwent immediate postmastectomy breast reconstruction with various types of implants have been analyzed prospectively over a 9-year period. Of these patients, 334 who completed their reconstruction were suitable for evaluation of their cosmetic outcome. The early complication rate (< 2 months) was 9.2 percent, with an explantation rate of 1.7 percent. The late complication rate (> 2 months) was 23 percent, with a pathological capsular contracture rate of 11 percent at 2 years and 15 percent at 5 years and an implant removal rate of 7 percent. The revisional surgery rate was 30.2 percent. The cosmetic results were assessed prospectively using an objective five-point global scale. Every patient was scored at each visit once surgery was completed. The overall cosmetic outcome deteriorated in a linear fashion, from an initial acceptable result of 86 percent 2 years after patients completed their reconstruction to only 54 percent at 5 years. This decline in cosmetic outcome was not associated with the type of implant used, the volume of the implant, the age of the patient, or the type of mastectomy incision employed. Radiotherapy was not a significant factor because only 28 patients were irradiated. Upon Cox model analysis, pathological capsular contracture was the only factor that contributed significantly to a poor cosmetic outcome in which p < 0.0001 (relative risk 6.3). Despite a high revisional surgery rate, deterioration still occurred, suggesting that other unaccounted for variables were responsible. On photographic retrospective review of the patients without capsular contracture who demonstrated deterioration in their cosmetic scores, it became clear that a possible reason for their poor results was late asymmetry produced by the failure of both breasts to undergo symmetrical ptosis with aging.

Prospective evaluation of late cosmetic results following breast reconstruction: II. Tram flap reconstruction.

Although it is thought that transverse rectus abdominis muscle (TRAM) flap breast reconstruction produces excellent cosmetic results that are maintained over the long term, there is little objective evidence in the literature to support this. One hundred seventy-one consecutive patients who underwent TRAM flap reconstruction were prospectively analyzed over an 8-year period to assess their morbidity and late cosmetic outcome.The early patient complication rate (< 2 months) was 37.4 percent, the late hernia and fat necrosis rates (> 2 months) were 8.8 and 13.5 percent, respectively, and the contralateral symmetrization rate was 33.9 percent. The cosmetic results were evaluated prospectively using an objective five-point global scale. Each patient was scored at each visit once surgery was completed. Follow-up continued until a flap was lost, a patient died, or the point of last patient contact was reached. Six patients died during the study. The actuarial percentage cosmetic outcome remained stable during the study period, with an acceptable result in 96.4 percent of patients at 2 years and in 94.2 percent of patients at 5 years. Only five patients in this series obtained poor cosmetic outcomes, with three due to substantial flap necrosis and two because of poor flap design. Two free TRAM flaps were also lost. Log-rank analysis revealed that neither patient age nor timing of surgery significantly affected the cosmetic outcome. Single pedicle and supercharged (single pedicle) TRAM flaps produced slightly better results than bipedicle and free TRAM flaps. In this prospective longitudinal study, TRAM flap reconstructions were shown to produce aesthetically pleasing results. Moreover, with long-term follow-up, it was demonstrated that these reconstructions maintained their stability.

Necrotising fasciitis of the breast.

Necrotising fasciitis is a rare condition and to the best of our knowledge has never been reported in the breast. We report the first case in the literature of necrotising fasciitis involving the breast.

Effects of a silicone-coated polyamide net dressing and calcium alginate on the healing of split skin graft donor sites: a prospective randomised trial.

An open randomised prospectively controlled trial was performed to assess the healing efficacy, slippage rate and degree of discomfort on removal of calcium alginate and a silicone-coated polyamide net dressing on split skin graft donor sites. Sixteen patients were randomised to the calcium alginate group and 14 to the silicone-coated group. The donor sites were assessed at days 7, 10, 14 and up to day 21. The mean time to healing in the calcium alginate group was 8.75 +/- 0.78 days (range 7 to 14 days) compared to 12 +/- 0.62 days (range 7 to 16 days) for the silicone-coated group (p < 0.01). Although more silicone-coated dressings slipped (5 versus 1), the difference was not statistically significant. Pain during the first dressing change was assessed using a visual analogue pain scale. Although no significant differences were found between the groups, it was necessary to change the dressing protocol in the silicone-coated arm of the trial after entering the first two patients. Overlaid absorbent gauze adhered to the donor site through the fenestrations in the dressing necessitating the placement of paraffin gauze between the experimental dressing and the overlying cotton gauze. There was one infection in the study, occurring in the alginate group. Based on these results we recommend calcium alginate as the dressing of choice for split skin graft donor sites.
