The effect of triclosan-coated sutures in wound healing. A double blind randomised prospective pilot study

BACKGROUND Wound infection and dehiscence are both major contributors to postoperative morbidity. One potential cause or co-factor is the use of suture material. A recently introduced subcutaneous suture is coated with triclosan (TC), an antiseptic drug. It is suggested to reduce wound complications. METHODS To investigate the effect of TC on wound healing a double blind prospective pilot study in women undergoing a breast reduction was performed. Each patient was her own control. After randomisation the TC-coated sutures were used either on the left or right side. The contralateral side was used as the control. The incidence of dehiscence was studied. RESULTS Twenty-six patients were included. In the TC breasts there was a wound dehiscence in 16 cases, whereas in the control breasts in seven cases a dehiscence was observed (P=0.023). CONCLUSION These results suggest that TC-coated sutures should be used with caution. These sutures have already been introduced on to the market without good clinical studies and might have potential adverse effects as shown by these data.

‘Reconstruction: Before or after postmastectomy radiotherapy?’ A systematic review of the literature

OBJECTIVE The aim of this review is to investigate the effect of timing of the reconstruction and radiotherapy, with respect to complication rate and cosmetic outcome, with a special focus on the timing of the placement of the definite implant. METHODS PubMed was searched for publications between January 2000 and December 2012. Of 37 eligible studies, timing of reconstruction, type, and incidence of complications were recorded. First, we calculated the weighted mean including confidence intervals for complications and cosmetic outcome overall, and for the following subgroups: (1) Autologous reconstruction after radiotherapy; (2) Definite implant reconstruction after radiotherapy; (3) Autologous reconstruction before radiotherapy; (4) Definite implant reconstruction before radiotherapy. A second analysis was performed using only studies that directly compared group 1 versus 3 and 2 versus 4. RESULTS A large variation in complication rates (8.7-70.0%) and in acceptable cosmetic outcome (41.4-93.3%) was reported. The first analysis showed more complications and a higher revision rate if an implant reconstruction was performed after radiotherapy; for autologous reconstruction fibrosis occurred more often if reconstruction was applied first. The second analysis showed no significant differences in total complication rate. Only implant failure occurred more often if applied after radiotherapy (odds ratio (OR) 3.03 [1.59-5.77]). No differences were found in both patient and physician satisfaction. CONCLUSIONS A definite implant reconstruction placed before radiotherapy limits the rate of complications. For autologous reconstruction, less fibrosis is seen if reconstruction is performed after radiotherapy, but timing had no significant impact on total complication rate.

Two-stage implant-based breast reconstruction compared with immediate one-stage implant-based breast reconstruction augmented with an acellular dermal matrix: an open-label, phase 4, multicentre, randomised, controlled trial

BACKGROUND The evidence justifying the use of acellular dermal matrices (ADMs) in implant-based breast reconstruction (IBBR) is limited. We did a prospective randomised trial to compare the safety of IBBR with an ADM immediately after mastectomy with that of two-stage IBBR. METHODS We did an open-label, randomised, controlled trial in eight hospitals in the Netherlands. Eligible women were older than 18 years with breast carcinoma or a gene mutation linked with breast cancer who intended to undergo skin-sparing mastectomy and immediate IBBR. Randomisation was done electronically, stratified per centre and in blocks of ten to achieve roughly balanced groups. Women were assigned to undergo one-stage IBBR with ADM (Strattice, LifeCell, Branchburg, NJ, USA) or two-stage IBBR. The primary endpoint was quality of life and safety was assessed by the occurrence of adverse outcomes. Analyses were done per protocol with logistic regression and generalised estimating equations. This study is registered at Nederlands Trial Register, number NTR5446. FINDINGS 142 women were enrolled between April 14, 2013, and May 29, 2015, of whom 59 (91 breasts) in the one-stage IBBR with ADM group and 62 (92 breasts) in the two-stage IBBR group were included in analyses. One-stage IBBR with ADM was associated with significantly higher risk per breast of surgical complications (crude odds ratio 3·81, 95% CI 2·67-5·43, p<0·001), reoperation (3·38, 2·10-5·45, p<0·001), and removal of implant, ADM, or both (8·80, 8·24-9·40, p<0·001) than two-stage IBBR. Severe (grade 3) adverse events occurred in 26 (29%) of 91 breasts in the one-stage IBBR with ADM group and in five (5%) of 92 in the two-stage IBBR group. The frequency of mild to moderate adverse events was similar in the two groups. INTERPRETATION Immediate one-stage IBBR with ADM was associated with adverse events and should be considered very carefully. Understanding of selection of patients, risk factors, and surgical and postsurgical procedures needs to be improved. FUNDING Pink Ribbon, Nuts-Ohra, and LifeCell.

No increase of local recurrence rate in breast cancer patients treated with skin-sparing mastectomy followed by immediate breast reconstruction

BACKGROUND The aim of this study was to evaluate the incidence of local recurrence after SSM with IBR and to determine whether complications lead to postponement of adjuvant therapy. METHOD Patients that underwent IBR after SSM between 2004 and 2011 were included. RESULTS A total of 157 reconstruction procedures were performed in 147 patients for invasive breast cancer (n = 117) and ductal carcinoma in situ (n = 40). The median follow-up was 39 months [range 6-97]. Estimated 5-year local recurrence rate was 2.9% (95% CI 0.1-5.7). The median time to start adjuvant therapy was 27.5 days [range 19-92] in 18 patients with complications, and 23.5 days [range 8-54] in 46 patients without complications (p = 0.025). CONCLUSION In our single-institution cohort, IBR after SSM carried an acceptable local recurrence rate. Complications caused a delay of adjuvant treatment but this was within guidelines and therefore not clinically relevant.

Single-stage breast reconstruction using Strattice™: A retrospective study.

INTRODUCTION Strattice™, a porcine acellular dermal matrix, has emerged as a product to augment implant-based breast reconstruction. It aims to resolve problems related to poor tissue coverage of the implant. Presently, evidence justifying the use of Strattice in breast reconstruction is lacking. The objective of this study is to assess the clinical outcomes of a patient cohort that underwent single-stage implant-based breast reconstruction with the additional use of Strattice. METHODS We conducted a retrospective chart review of patients who underwent single-stage breast reconstruction with the use of Strattice. All cases of breast reconstruction after oncologic or prophylactic mastectomy between 2010 and 2014 in one of eight different centres in the Netherlands were included. Patient demographics, treatment characteristics and clinical outcome data were collected. The outcomes were presented using descriptive statistics, and the associations were evaluated using Fishers exact test. RESULTS Eighty-eight patients who underwent either unilateral (60 patients) or bilateral (25 patients) (n = 110 breasts) single-stage breast reconstruction with the use of Strattice were identified. The indication for mastectomy was therapeutic in 69.1% (76) of cases and prophylactic in 30.9% (34) of cases. The reported minor complications included seroma (20.9%), skin necrosis (20.0%), wound dehiscence (11.8%), erythema/inflammation (14.5%) and infection (11.8%). In 22 breasts (22.7%), reoperation was necessary, with explantation of the implant in 11 breasts (11.8%). CONCLUSIONS In this cohort, the total complication rate was very high (78%). Although most complications were minor, reoperation was performed in 22.7%, with explantation of the implant in 11.8% of breasts. We suggest that patient selection, experience of the surgeon and handling of early complications are factors playing a crucial role in the success of the operation. The use of a Strattice sheet in single-stage implant-based breast reconstruction may be a promising technique, but more evidence from prospective, randomized studies is necessary to justify its use.

A novel therapeutic strategy for turban tumor: scalp excision and combined reconstruction with artificial dermis and split skin graft

Brooke–Spiegler syndrome is a hereditary tumor predisposition disorder characterized by the development of cylindromas, trichoepitheliomas, and spiradenomas. Predilection sites of the disease are hair follicles and sweat glands of the head and neck. In some patients, the tumors can coalesce to so‐called turban tumors, which then usually cause cosmetic, psychological, and functional impairment. A curative therapy is not yet available, and thus total scalp excision followed by split skin graft is evolving as a frequently applied therapy. However, this treatment can lead to the formation of a thin and vulnerable skin, which hampers wearing a wig. Therefore, a more robust and functional solution is preferable. Here, we report on a woman with a turban tumor who suffered enormously from the disease and had secluded herself from social life.

Anatomical evaluation of the internal mammary vessels based on magnetic resonance imaging (MRI).

INTRODUCTION The rib-sparing technique to access the internal mammary vessels for microanastomosis is the current practice in our hospital nowadays. This study is performed to analyse the best intercostal space to expose those vessels. PATIENTS AND METHODS Magnetic resonance imaging (MRI) of the chest wall of 133 women was evaluated. The Schwabegger classification (representing the anatomical variation), the intercostal space between ribs two, three and four, and the surface of the internal mammary artery and veins in the second and third intercostal space were determined on multiplanar reconstructed T2-weighted images. RESULTS In more than half of the cases, the anatomy followed Schwabegger variation two; one lateral artery and one medial vein were symmetrical. If a second vein was present, the bifurcation was most commonly in the third intercostal space. The second intercostal space above the mammary vessels was significantly wider than the third one. The surface of the artery and vein(s) was significantly larger in the second intercostal space. CONCLUSION In most clinical situations, the second intercostal space is most likely the best approach to the internal mammary vessels for microanastomosis using a rib-sparing technique because of wider intercostal space and larger artery and vein.

Substantial chest-wall deformity following tissue expansion after radiotherapy

We present the case of a 54-year-old woman who underwent a two-stage breast reconstruction with a tissue expander after sustaining a lumpectomy and local radiotherapy for breast cancer. During expansion, the woman developed an abnormal concave deformity of the chest wall. Although respiratory or aesthetic consequences were expected, our patient reported only pain and was satisfied with the end result. Osteoporosis or local recurrence was excluded as predisposing factors, and radiotherapy was considered to be the causal factor in our patient. On the basis of this finding, we advise surgeons to take the risk of chest-wall deformity into consideration when planning a reconstruction with tissue expanders, especially in patients with a history of radiotherapy, and we recommend an alternative reconstructive method in this group of patients.

Sensory recovery of the breast after innervated and non-innervated autologous breast reconstructions: A systematic review

BACKGROUND The sensory recovery of the reconstructed breast is an undervalued topic in the field of autologous breast reconstruction. This systematic review aimed to evaluate the available literature on the sensory recovery of the breast after innervated and non-innervated autologous breast reconstructions and to assess the possible benefits of sensory nerve coaptation compared to spontaneous reinnervation of the flap. METHODS A comprehensive literature search was conducted in PubMed, Embase and the Cochrane Library to identify all eligible studies regarding the sensory recovery of all types of innervated and non-innervated autologous breast reconstructions. RESULTS The search yielded 334 hits, of which 32 studies concerning 1177 breast reconstructions were included. The amount of heterogeneity between the studies was high, which made the pooling of data difficult. The studies indicated that spontaneous reinnervation of autologous breast reconstructions occurred to a variable extent, depending on how and when it was measured. Despite these variable results, the sensory recovery of innervated flaps, however, was superior, started earlier and gradually improved over time with a higher chance of approaching normal values than non-innervated flaps. There is a lack of studies that assess the return of erogenous sensation and quality of life. CONCLUSION The current evidence shows that nerve coaptation results in superior sensory recovery of the reconstructed breast compared to spontaneous reinnervation of the flap. This review illustrates that more standardised, high-quality studies with adequate sample sizes are needed to objectively evaluate the sensory recovery of the breast after autologous breast reconstructions.

Equilibrium-Phase High Spatial Resolution Contrast-Enhanced MR Angiography at 1.5T in Preoperative Imaging for Perforator Flap Breast Reconstruction

Objectives The aim was (i) to evaluate the accuracy of equilibrium-phase high spatial resolution (EP) contrast-enhanced magnetic resonance angiography (CE-MRA) at 1.5T using a blood pool contrast agent for the preoperative evaluation of deep inferior epigastric artery perforator branches (DIEP), and (ii) to compare image quality with conventional first-pass CE-MRA. Methods Twenty-three consecutive patients were included. All patients underwent preoperative CE-MRA to determine quality and location of DIEP. First-pass imaging after a single bolus injection of 10 mL gadofosveset trisodium was followed by EP imaging. MRA data were compared to intra-operative findings, which served as the reference standard. Results There was 100% agreement between EP CE-MRA and surgical findings in identifying the single best perforator branch. All EP acquisitions were of diagnostic quality, whereas in 10 patients the quality of the first-pass acquisition was qualified as non-diagnostic. Both signal- and contrast-to-noise ratios were significantly higher for EP imaging in comparison with first-pass acquisitions (p<0.01). Conclusions EP CE-MRA of DIEP in the preoperative evaluation of patients undergoing a breast reconstruction procedure is highly accurate in identifying the single best perforator branch at 1.5Tesla (T). Besides accuracy, image quality of EP imaging proved superior to conventional first-pass CE-MRA.
