Comparison of the Explantation Rate of Poly Implant Prothèse, Allergan, and Pérouse Silicone Breast Implants within the First Four Years after Reconstructive Surgery before the Poly Implant Prothèse Alert by the French Regulatory Authority.

2015

Background. In March 2010, ANSM (Agence Nationale de Sécurité du Medicament), the French Medical Regulatory Authority, withdrew Poly Implant Prothèse (PIP) breast implants from the market due to the use of non-medical-grade silicone gel. The aim of this study was to compare the removal rate (and reasons thereof) of breast implants produced by different manufacturers before the ANSM alert. Materials and Methods. From October 2006 to January 2010, 652 women received 944 implants after breast cancer surgery at the Gustave Roussy Comprehensive Cancer Center, Paris (France). The complications and removal rates of the different implant brands used (PIP, Allergan, and Pérouse) were evaluated and compared. Results. PIP implants represented 50.6% of the used implants, Allergan 33.4%, and Pérouse 16%. The main reasons for implant removal were patient dissatisfaction due to aesthetic problems (43.2%), infection (22.2%), and capsular contracture (13.6%). Two years after implantation, 82% of Pérouse implants, 79% of PIP, and 79% of Allergan were still in situ. There was no difference in removal rate among implant brands. Conclusion. Before the ANSM alert concerning the higher rupture rate of PIP breast implants, our implant removal rate did not predict PIP implant failure related to the use of nonapproved silicone gel. read more

[Fasciae latae perforator flap for breast reconstruction: An attractive alternative in case of DIEP contraindication].

Feb, 2017

The musculocutaneous tensor fascia latae flap was one of the first free flaps described. It is possible to harvest a flap with the same skin paddle, vascularized by a septo-cutaneous perforator running through the tensor fascia lata muscle septum and coming from the ascending branch of the lateral circumflex femoral artery. The DIEP is currently the workhorse of autologous breast reconstruction, but there are some contraindications. The septo-cutaneous tensor fascia latae perforator flap may be an alternative for women with lateral upper thigh lipodystrophy. Between 2010 and 2014, three flaps have been performed in two patients for delayed breast reconstruction (one case of unilateral reconstruction, and one bilateral). Perforators were identified by preoperative angiography. The intervention was performed in a two-team approach, in only one operative position. Perforators were located in the horizontal axis of the upper rim of the pubis bone. One perforator artery was dissected for each flap. The mean caliber of the pedicle was 2.8mm, and the mean length was 6.4cm. The operative time was 240minutes for unilateral flap, 375minutes for bilateral flap. There was no case of total or partial necrosis, or complications on the donor site. Cosmetic results were considered satisfying by patients and surgeons with the reconstructed breast as well as the donor site. Septo-cutaneous fascia lata perforator flap is an attractive flap for breast reconstruction in patients with DIEP contraindication and lateral upper thigh lipodystrophy. It has many advantages: easy to harvest, length and calibre of the pedicle, double team approach, only one operating position, quality of reconstruction. It is necessary to carry out a larger series of cases to study the complication rate in the donor site. read more

Remote peripheral tissue oxygenation does not predict postoperative free flap complications in complex head and neck cancer surgery: A prospective cohort study.

Feb, 2017

Patients undergoing free flap reconstruction after head and neck cancer may develop free flap complications. In the perioperative period, haemoglobin content and oxygen tissue saturation (StO) measured directly on the free flap reflect peripheral tissue oxygenation. However, in this type of surgery, StO cannot always be applied directly or proximate to the free flap. The aim of this study was to assess the possible value of StO measured at the thenar eminence and other 24hour perioperative factors on free flap complications. read more

Autologous tracheal replacement for cancer.

Dec, 2015

Surgical research has failed during fifty years to find an ideal substitute for the trachea after extended resection. All the prostheses could erode the adjacent structures or lead to infection or obstructive issues. Innovation in surgery development has been improved using novel techniques of plastic surgery. During the last ten years, we have developed a technique using free fasciocutaneous flaps. This allows us to construct tubes for tracheal replacement. The most accurate flap used for this technique is the forearm free flap (FFF). Reinforcement of the flap with autologous strips of cartilage harvested from the last ribs offers sufficient resistance to respiratory pressure. This technique is also completely autologous without any stent in the tracheal lumen. From 2004 to 2015 we have already reconstructed the trachea of 16 patients for 12 primary tracheal neoplasms [including 9 adenoid cystic carcinoma (ACC) and 3 squamous cell carcinoma (SCC)], 3 secondary tracheal Neoplasms and one for benign lesion. This article describes the indications, determination of resectability, patient selection, subheading for surgery, postoperative management and results of this technique. read more

Occult cancer in specimens of reduction mammaplasty aimed at symmetrization. A multicentric study of 2718 patients.

Jun, 2015

Women who have undergone surgical treatment for breast cancer often benefit from a contralateral reduction mammaplasty (CRM) aimed at symmetrization of the contralateral breast unaffected by the initial cancer. In our 7-year multicentric study (12 centers) of 2718 patients, incidence of CRM cancers (CRMc) was 1.47% (n = 40) [95% CI 1.05%-2.00%]. The CRMc group had significantly more initial mammary cancers of invasive lobular carcinoma (ILC, 22.5% vs 12.0%) and ductal carcinoma in situ (DCIS, 35.0% vs 21.6%) types than the healthy CRM group (p = 0.017). 35.0% (n = 14) of patients had en bloc resection; 25.0% (n = 10) of surgical specimens were correctly oriented. En bloc resection and orientation of surgical specimens enable precise pinpointing of the CRMc. A salvage lumpectomy may be proposed as an option when margins are invaded. The histological distribution of the 40 CRMc (mean size 12.7 mm) was carcinoma in situ (CIS) 70%, ILC 12.5%, invasive ductal carcinoma (IDC) 12.5% and tubular carcinoma (TC) 5.0%. read more

The Laryngoscope

Pharyngotracheal fistula closure using the internal mammary artery perforator island flap.

May, 2014

Salvage laryngectomy following organ preservation therapy is a frequent condition that exposes patients to pharyngocutaneous and pharyngotracheal fistulas. Definitive treatment frequently requires well vascularized tissue harvested from the chest. To limit tracheostoma obstruction, a thin and pliable flap is preferable. The internal mammary artery perforator (IMAP) island flap fulfills these criteria, but it is not well known and is not commonly used by head and neck surgeons. In this article, based on our experience, we describe our surgical technique and the strengths and weaknesses of this flap. read more

Cervicothoracic reconstruction with an anteromedial thigh flap: a novel flap concept.

Jun, 2013

The anteromedial thigh region is more popular as a donor site for skin graft than for flap. It is an extended area whose limits are poorly defined. This explains why flaps vascularised by different source arteries but described under the same name can be found in the literature introducing confusion and misunderstanding. This confusion was introduced since the primary descriptions as Baek presented in 1983 an anteromedial skin flap whose source artery was the superficial femoral artery and Song published a year later, under the same name, a flap vascularised by the innominate descending branch of the lateral circumflex femoral artery. Whatever the name and the source artery, the anteromedial thigh region is an under-exploited region which can be useful in the case of composite and complex defects. Anteromedial thigh flaps, either as pedicled or as a microvascular free-tissue transfer, were used in reconstructive surgery. We here describe a chimeric flap of the anteromedial thigh region and used as a flow-through flap. read more

Modification of flap design for total mobile tongue reconstruction using a sensitive antero-lateral thigh flap.

Jul, 2012

Reconstruction of large carcinologic tongue defect is mandatory to recover adequate speech and swallowing. Free flaps provide thin and pliable tissues needed to restore the shape and the volume of the tongue but their functional outcomes, especially in case of total mobile tongue reconstruction, are still limited. The authors describe a modification of flap design called the 'cathedral triptych' used with the antero-lateral thigh flap. This modified design recreates a near normal neotongue shape with more projected tip and vertical bulk that can contact the palate and the upper lip. Ten patients underwent total mobile tongue reconstruction with a sensitive antero-lateral thigh flap and a 'cathedral triptych' design. This modification of flap shaping and folding optimises postoperative oral function. read more

Axillary Padding without Drainage after Axillary Lymphadenectomy - a Prospective Study of 299 Patients with Early Breast Cancer.

Jun, 2012

BACKGROUND: After lymphadenectomy for early breast cancer, seroma formation is a constant event requiring a suction drainage. This drainage is the strongest obstacle to reducing the hospital stay. Axillary padding without drainage appears to be a valuable option amid the various solutions for reducing the hospital stay. METHODS: We conducted a comparison between 114 patients with padding and 185 patients with drainage. Data were obtained from 2 successive prospective studies. RESULTS: The mean hospital stay was 2.4 days (range 1-4) in the padding group and 4.2 days (range 2-9) in the drainage group (p < 0.05). There were fewer needle aspirations for seroma in the padding group (8.8 vs. 23%, p < 0.05). At 6 weeks, only 28% (32/114) of the patients in the padding group reported pain versus 51% (94/185) in the drainage group. The mean pain intensity at 6 weeks was 3 and 4.3 respectively (p < 0.0001). CONCLUSION: Axillary padding without drainage was associated with a better post-operative course than suction drainage in this historical comparison, and the hospital stay was significantly shortened. There are only few series published on this new technique but they all indicate good feasibility and good tolerance. A large randomised multicentric evaluation is now warranted. read more
