ABSTRACT

BACKGROUND: The transverse upper gracilis flap is an important reconstructive option for patients who desire autologous reconstruction after mastectomy but in whom a deep inferior epigastric perforator flap is unavailable or undesirable. The authors present an analysis of outcomes and patient satisfaction results, from a consecutive series in a single institution. METHODS: Using a prospectively populated free flap database, all patients undergoing transverse upper gracilis flap breast reconstruction for a mastectomy defect between January of 2013 and December of 2017 were identified. Retrospective review of clinical notes, admissions, and discharge information was conducted to identify outcomes, secondary operations, and complications. All patients were contacted by letter and invited to take part in a patient satisfaction survey a minimum of 12 months after free-flap surgery. RESULTS: Seventy-eight patients underwent transverse upper gracilis flap breast reconstruction using a total of 103 transverse upper gracilis flaps to reconstruct 99 breast mounds in the 5-year period studied. Patient satisfaction is evidenced by BREAST-Q scores showing 81 ± 19 percent Satisfaction with Breasts, 80 ± 20 percent Psychosocial Well-Being, and 84 ± 19 percent Physical Well-Being of the chest. Forty-six of 53 (87 percent) report satisfaction with the postoperative appearance of their thigh unclothed and 51 of 53 (96 percent) report satisfaction clothed. CONCLUSIONS: This is the first consecutive series of transverse upper gracilis flap breast reconstruction outcomes that presents BREAST-Q scores for multiple, postoperative reconstruction modules and details complications stratified by Clavien-Dindo score. The methodology can be easily replicated and benchmarked against. Our donor-site complication rates are lower than previous publications and patient satisfaction data reveal that this is a well-accepted option for patients. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, IV.

ABSTRACT

BACKGROUND: The superficial circumflex iliac artery perforator (SCIP) flap is a versatile option of free tissue transfer for small to large defects. In this study, we examine the advantages of the SCIP flap, its cadaveric anatomy, and clinical subtypes. METHODS: Ten cadavers were dissected and the corresponding pedicles of the SCIP and groin flaps were identified. A retrospective review of 20 clinical cases of free SCIP flap reconstruction was undertaken. The indication for reconstruction, flap dimensions, and survival were analyzed. A systematic literature review was conducted including articles that have previously reported the use of the SCIP flap. RESULTS: The SCIP pedicle was present in all our cadaveric dissections. The starting point of its pedicle ranged from 1.5 to 4.5 cm along the superficial circumflex iliac artery. The median diameter of the perforator and its concomitant vein was 1mm (range 0.8-2 mm). A cutaneous vein (1.3-2.3 mm) could be included in the flap if the concomitant vein was too small. Twenty consecutive patients had free SCIP flaps between 2002 and 2018. The indications were for finger defects (n = 8), thumb reconstruction (n = 1), lower limb compound fractures (n = 3), iatrogenic wounds (n = 2), upper limb large defects (n = 2), and scar contractures (n = 4). Flap dimensions ranged from 2 × 4 cm to 14 × 25cm, and the longest pedicle was 8cm. All flaps survived. The systematic literature review identified 34 previous reports using the SCIP flaps, most of these published by Asian units. CONCLUSION: The SCIP flap is useful for reconstruction throughout the body due to its ease of dissection, thinness, adjustable pedicle length, and flap dimension ranging from tiny to large, as well as the feasibility of raising a compound flap incorporating an adipofascial or vascularized bone component if necessary.This is a level of evidence therapeutic IV study.

ABSTRACT

INTRODUCTION: The aim of this study was to determine the ability of MRI to identify and assess the extent of disease in patients with pathological nipple discharge (PND) with an occult malignancy not evident on standard pre-operative evaluation with mammography and ultrasound. METHODS: Patients presenting to the breast unit of Imperial College Healthcare NHS Trust between December 2009 and December 2018 with PND and normal imaging were enrolled in the study. Pre-operative bilateral breast MRI was performed in all patients as part of our protocol and all patients were offered diagnostic microdochectomy. RESULTS: A total of 82 patients fulfilled our selection criteria and were enrolled in our study. The presence of an intraductal papilloma (IDP) was identified as the cause of PND in 38 patients (46.3%), 14 patients had duct ectasia (DE-17%) and 5 patients had both an IDP and DE. Other benign causes were identified in 11 patients (13.4%). Despite normal mammography and ultrasound a malignancy was identified in 14 patients (17%). Eleven patients had DCIS (13.4%), two had invasive lobular carcinoma and one patient had an invasive ductal carcinoma. The sensitivity of MRI in detecting an occult malignancy was 85.71% and the specificity was 98.53%. The positive predictive value was 92.31% and the negative predictive value was 97.1%. CONCLUSIONS: Although a negative MRI does not exclude the presence of an occult malignancy the high sensitivity and specificity of this diagnostic modality can guide the surgeon and alter the management of patients with PND.

ABSTRACT

A role for complement, particularly the classical pathway, in the regulation of immune responses is well documented. Deficiencies in C1q or C4 predispose to autoimmunity, while deficiency in C3 affects the suppression of contact sensitization and generation of oral tolerance. Complement components including C3 have been shown to be required for both B-cell and T-cell priming. The mechanisms whereby complement can mediate these diverse regulatory effects are poorly understood. Our previous work, using the mouse minor histocompatibility (HY) model of skin graft rejection, showed that both C1q and C3 were required for the induction of tolerance following intranasal peptide administration. By comparing tolerance induction in wild-type C57BL/6 and C1q-, C3-, C4- and C5-deficient C57BL/6 female mice, we show here that the classical pathway components including C3 are required for tolerance induction, whereas C5 plays no role. C3-deficient mice failed to generate a functional regulatory T (Treg) -dendritic cell (DC) tolerogenic loop required for tolerance induction. This was related to the inability of C3-deficient DC to up-regulate the arginine-consuming enzyme, inducible nitric oxide synthase (Nos-2), in the presence of antigen-specific Treg cells and peptide, leading to reduced Treg cell generation. Our findings demonstrate that the classical pathway and C3 play a critical role in the peptide-mediated induction of tolerance to HY by modulating DC function.
