DIEP皮瓣与背阔肌肌皮瓣再造一侧乳房时对侧乳房处理的比较

目的：探讨DIEP（腹壁下动脉穿支,deepinferiorepigasticperforator,简称DIEP）皮瓣与背阔肌肌皮瓣再造一侧乳房时对侧乳房处理策略的比较。方法：2006年7月至2009年10月,选取15例保留乳头乳晕的乳癌改良根治术和10例Poland综合征的患者,其中12例行一侧DIEP皮瓣再造,余13例行一期背阔肌肌皮瓣转移并植入扩张器,术前对侧乳房下垂,3～5个月后二期乳房行假体置换扩张器,如双侧乳房不对称,同时进行对侧乳房的乳房缩小处理,期望能达到两侧对称性。结果：10例DIEP再造的乳房与对侧基本对称,另外2例要求二期修整。13例背阔肌肌皮瓣要求处理对侧下垂乳房,经处理后,与DIEP再造乳房相比,对称性仍感不足。结论：与DIEP乳房再造相比,背阔肌肌皮瓣乳房再造之后为了达到两侧乳房对称,处理对侧乳房是必要的。

Smoking increases donor site complications in breast reconstruction with DIEP flap

Objective: Reconstruction with deep inferior epigastric perforator flap (DIEP) is considered to be the first choice for autologous breast reconstruction. The primary aims of this retrospective study were to find out if differences in smoking habits and BMI are useful predictors for postoperative complications in DIEP surgery.

Methods: Three hundred and one patients were included. Data regarding smoking habits, BMI, age at surgery, total and final flap weight, abdominal scars, parity, number of perforators, chemotherapy, post mastectomy radiation therapy, and preoperative mapping of perforators with either Computer Tomography Angiography or hand-held ultra sound Doppler were collected. Complications that occurred in the first 30 postoperative days were taken into account.

Results and conclusions: It was found that former smokers had a risk for donor site complication more than double that of never smokers (OR =2.12, CI =1.10–4.10, p?=?0.025). Differences in BMI within the range from 18–33.7 did not have any significant impact on complication rates, neither at the donor site nor at the breast.     

Intraoperative venous congestion in free transverse rectus abdominis musculocutaneous and deep inferior epigastric artery perforator flaps during breast reconstruction: A systematic review

BACKGROUND:

Even with patent deep inferior epigastric vein anastomoses, venous congestion can occur during free transverse rectus abdominis musculocutaneous (TRAM) or deep inferior epigastric artery perforator (DIEP) flap surgery and lead to flap compromise if not recognized and managed.

OBJECTIVES:

To identify the incidence of intraoperative venous congestion and describe the best available prevention and treatment methods.

METHODS:

Systematic electronic searches of the PubMed database including Medline were performed to identify studies published until 2014. The following keywords were used: “DIEP” or “free TRAM” and “venous insufficiency” or “venous congestion”. Supplemental searches were conducted to identify referenced studies. Statistical analysis using the χ² test was performed.

RESULTS:

Nine studies representing 4747 free abdominal flaps cases were included and demonstrated an overall incidence of intraoperative venous congestion of 2.8%. The incidence in DIEP flaps (3.3%) was significantly higher than that in the free TRAM flaps (1.0%). All nine articles reported using the superficial inferior epigastric vein to treat venous insufficiency.

CONCLUSION:

The risk for developing intraoperative venous congestion following free abdominal flap breast reconstruction is influenced by inadequate perforator selection and persistent dominance in the superficial venous system. The solution is establishing another venous draining route using the superficial inferior epigastric vein.     

The unilateral deep inferior epigastric perforator flap: Comparing university to community hospital

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.     

Factors that predict deep inferior epigastric perforator flap donor site hernia and bulge

Abstract

Deep inferior epigastric artery perforator (DIEP) flap has become the gold standard in autologous breast reconstruction. Attention is now being focused on the impact of DIEP flap harvest technique on abdominal hernia rates. The aim of this study was to evaluate DIEP abdominal wall morbidity in relation to flap harvest and fascial closure technique. A retrospective analysis of patients undergoing DIEP flap breast reconstruction between 2012 and 2016 was performed. Post-operative evaluation of the abdominal wall integrity was performed by an operating consultant. The rectus fascia was closed using one of three techniques. The study included 202 patients, in whom 234 DIEP flaps were performed. Eight patients (3.4%) developed a clinically evident abdominal bulge post-operatively and one (0.5%) had a hernia. Harvesting two or more perforators was more likely to result in post-operative abdominal hernia/bulge than taking a single perforator (p?=?.032). Using a perforator from the lateral row or both rows was more likely to result in a hernia/bulge than if a single medial perforator was harvested (p?=?.026). Comparison of the rectus fascia closure technique did not show any statistically significant difference in abdominal wall morbidity. Consideration should be given towards perforator selection when harvesting a DIEP flap. Where appropriate, a suitable single medial row perforator with a favourable suprafascial course should be chosen. This study has not shown mesh-free fascial closure to be inferior to mesh-supported closure. Careful consideration to the role of synthetic mesh within this patient cohort should be given.
