Mastectomy skin flap necrosis (MSFN) and partial DIEP (deep inferior epigastric artery perforator) flap loss represent two frequently reported complications in immediate autologous breast ...reconstruction. These complications could be prevented when areas of insufficient tissue perfusion are detected intraoperatively. Hyperspectral imaging (HSI) is a relatively novel, non-invasive imaging technique, which could be used to objectively assess tissue perfusion through analysis of tissue oxygenation patterns (StO
%), near-infrared (NIR%), tissue hemoglobin (THI%), and tissue water (TWI%) perfusion indices. This prospective clinical pilot study aimed to evaluate the efficacy of HSI for tissue perfusion assessment and to identify a cut-off value for flap necrosis. Ten patients with a mean age of 55.4 years underwent immediate unilateral autologous breast reconstruction. Prior, during and up to 72 h after surgery, a total of 19 hyperspectral images per patient were acquired. MSFN was observed in 3 out of 10 patients. No DIEP flap necrosis was observed. In all MSFN cases, an increased THI% and decreased StO
%, NIR%, and TWI% were observed when compared to the vital group. StO
% was found to be the most sensitive parameter to detect MSFN with a statistically significant lower mean StO
% (51% in the vital group versus 32% in the necrosis group,
< 0.0001) and a cut-off value of 36.29% for flap necrosis. HSI has the potential to accurately assess mastectomy skin flap perfusion and discriminate between vital and necrotic skin flap during the early postoperative period prior to clinical observation. Although the results should be confirmed in future studies, including DIEP flap necrosis specifically, these findings suggest that HSI can aid clinicians in postoperative mastectomy skin flap and DIEP flap monitoring.
Summary 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.
Objective. The aim of this study is to examine the experience of European surgeons on autologous fat transfer (AFT) and highlight differences between countries and levels of experience. Background ...Data. The popularity of AFT causes an increase in sophisticated scientific research and clinical implementation. While results from the former are well-documented, important aspects of the latter are far less recognized. Methods. An international survey study about surgeon background, besides AFT familiarity, technique, and opinion, was distributed among surgeons from 10 European countries. The differences between countries and levels of experience were analyzed using a logistic regression model. Results. The mean respondent age, out of the 358 completed questionnaires, was 46 years. Ninety-seven percent of the respondents were plastic surgeons, who practiced AFT mostly in breast surgery and considered themselves experienced with the technique. The thigh and abdomen were less favored harvest locations by the Belgium and French respondents, respectively, and both the French and Austrian respondents preferred manual aspiration over liposuction in harvesting the fat. Despite minor differences between countries and experience, the intraglandular space was injected in all subgroups. Conclusions. The expanding use of AFT in Europe will lead to more experience and heterogeneity regarding the technique. However, despite an obvious adherence to Coleman’s method, deviations thereof become more apparent. An important example of such a deviation is the ongoing practice of intraglandular AFT despite being a contraindication in various European guidelines. These unsafe practices should be avoided until scientific clarification regarding oncological safety is obtained and should therefore be the focus of surgeon education in Europe.
Objective. The aim of this study is to compare the cosmetic evaluation of autologous fat transfer (AFT) for various indications between surgeons and different laymen groups. Background Data. Despite ...the upsurge in AFT scientific/clinical interest, objectifying satisfaction has only recently progressed beyond simple Likert-type/Visual Analog Scales. Furthermore, differences in satisfaction between laymen and surgeons has not been thoroughly studied. Method. A photo comparison study between European plastic surgeons and different laymen groups was conducted to investigate agreement on cosmetic evaluation of AFT. Three sets of preoperative/postoperative photographs illustrating patients treated with External Vacuum Expansion (EVE) + AFT for various indications in breast surgery were scored according to the Harris Scale, and the interrater agreement was analyzed using Cohen’s κ. Results. The overall agreement between the surgeons and the groups of former augmentation, control group, and deep inferior epigastric artery perforator patients was fair, moderate, and substantial, respectively. Interrater agreements among different laymen groups and surgeons from different countries among themselves was substantial to almost perfect. Finally, we found that laymen are generally more optimistic about postoperative results than surgeons. Conclusion. In our study, former augmentation patients showed the lowest agreement with surgeons, in the cosmetic appreciation of EVE + AFT and this group might benefit from a more thorough preoperative consultation regarding expectations when choosing AFT. However, overall laymen tend to be more optimistic about postoperative results and surgeon education in general does not seem influenced by surgeon nationality. The significant differences between surgeons and laymen in the cosmetic evaluation of EVE + AFT justifies further studies that focus on the qualitative aspects of these differences to further balance patients’ and surgeons’ expectations.
Abstract
The deep inferior epigastric perforator (DIEP) flap is considered to be the gold standard for autologous breast reconstruction. This study evaluates the outcome of unilateral DIEP flap ...reconstructions, comparing university with a community hospital setting. A total of 77 unilateral DIEP flaps were performed at one university hospital and two community hospitals by the same two surgeons. Outcome parameters were: hospital stay, operating time, wound infection, wound dehiscence, fat necrosis, haematoma, (partial) flap necrosis and the need for surgical intervention. Forty-nine unilateral DIEP flaps were performed in the university hospital and 28 in the community hospitals. Baseline characteristics were equal. No significant difference was found in total complication rate, flap loss or need for surgical intervention. Although wound dehiscence occurred more often in the community hospitals, unilateral DIEP flap breast reconstructions can be performed with a comparable degree of safety and complication risk in both university and community hospital settings.
The fascia temporalis is a thin and well-vascularized tissue and, for this reason, its use in reconstructive surgery is versatile. It can be used as an island flap in defects of the head and neck or ...as a free flap in reconstructions of different anatomic regions. As a "living" spacer in the treatment of wrist ankylosis, its use has not yet been described. The authors present the transfer of the free fascia temporalis into the wrist as a treatment of wrist ankylosis in patients affected by severe rheumatoid arthritis. Four flaps in three patients were performed. Preoperative flexion/extension in the wrist was absent or almost absent and painful, resulting in severely impaired daily activities. After resection of the distal ulna, distal radius, and the proximal surfaces of the proximal row of the carpal bones was performed, the free fascia was used to replace the wrist joint. Postoperative wrist flexion/extension was 45 to 50 degrees on average. In all patients, this procedure allowed painless motion of the wrist, and in all patients, daily activities were improved. A 2-year follow up showed no recurrence of wrist problems and a maintained articular space. In the treatment of wrist ankylosis, the use of the free fascia temporalis offers a good alternative to arthrodesis, maintaining sufficient function for daily activities.
