Staged Suprapectoral Expander/Implant Reconstruction without Acellular Dermal Matrix following Nipple-Sparing Mastectomy

Q2 · MEDICINE

Article

Author: Harness, Jay K ; Salibian, Arthur H ; Mowlds, Donald S

Background:Since the introduction of nipple-sparing mastectomy as an oncologically safe procedure for the treatment of breast cancer, reconstructive efforts for immediate staged expander/implant reconstruction have focused on submuscular implantation with or without acellular dermal matrix. Suprapectoral reconstruction without acellular dermal matrix has received little attention in the reconstructive literature of nipple-sparing mastectomy.Methods:Between 2005 and 2015, 155 patients (250 breasts) underwent nipple-sparing mastectomy with prepectoral staged expander/implant reconstruction using thick mastectomy skin flaps without acellular dermal matrix. Patients with different breast sizes, including those patients with very large breasts who required a primary mastopexy, were considered candidates for the suprapectoral reconstruction. Tumor-related data, comorbidities, and preoperative or postoperative radiation therapy were evaluated for correlation with the final outcome.Results:Patients were followed up for an average of 55.5 months (range, 138.1 to 23.6 months). The tumor recurrence rate was 2.6 percent. Adverse outcomes such as capsular contracture, implant dystopia, and rippling were studied. Aesthetic outcome, based on a three-point evaluation scale, showed 53.6 percent of patients as having a very good result, 31.6 percent showing a good result, 9 percent showing a fair result, and 5.8 percent showing a poor result.Conclusions:The suprapectoral two-stage expander/implant reconstruction without acellular dermal matrix in nipple-sparing mastectomy has certain advantages with respect to breast shape, less morbidity related to expansion, ease of reconstruction, and cost effectiveness. These advantages have to be weighed against those of subpectoral reconstruction with acellular dermal matrix to determine the method of choice.CLINCAL QUESTION/LEVEL OF EVIDENCE:Therapeutic, IV.

[Cup dissociation after reduction of a dislocated hip hemiarthroplasty].

Article

Author: Loubignac, F ; Boissier, F

PURPOSE OF THE STUDYClose reduction of a bipolar hemiarthroplasty dislocation may induce dissociation between the cup and the prosthetic ball head. This rare complication leads to reoperation.CASE REPORTTwo women 84 and 85 years' old suffering from femoral head fracture were treated by bipolar hemiarthroplasty through a postero-lateral approach. After the first post-operative month, a posterior dislocation has occurred. Close reduction, without anesthesia dislocated the intraprosthetic joint.DISCUSSIONDislocation rate is lower for bipolar hemiarthroplasty than for total hip arthroplasty. Reason for these two dislocation was supposed to be a "bottle-opener" effect's by locking the cup on to the posterior acetabular rim. Limb traction is responsible for intra-prosthetic iatrogenic dislocation.CONCLUSIONAnesthesia should be considered as necessary for prosthesis bipolar hemiarthroplasties dislocation treatment. The authors have moved to a different implant and modified their surgical approach (antero lateral). These modifications were introduced in order to reduce the rate of hip dislocation and above all the event of intraprosthetic dislocation when close reduction was necessary.

Do We Need Support in Prepectoral Breast Reconstruction? Comparing Outcomes with and without ADM

Article

Background:The majority of two-stage prepectoral breast reconstruction has been described utilizing acellular dermal matrix (ADM). Although reports of prepectoral breast reconstruction without ADM exist, there is a paucity of comparative studies.Methods:A single-institution retrospective review was performed of consecutive patients undergoing immediate prepectoral two-stage breast reconstruction with tissue expanders from 2017 to 2019. Short-term reconstructive and aesthetic complications were compared between cases that utilized ADM for support and those that did not.Results:In total, 76 cases (51 patients) were identified, of which 35 cases utilized ADM and 41 did not. Risk factors and demographics were similar between the two cohorts with the exception of body mass index, which was higher in the ADM cohort (29.3 versus 25.4, P = 0.011). Average follow-up length was also longer in patients who received ADM (20.3 versus 12.3 months, P < 0.001). Intraoperative expander fill was higher in patients who did not receive ADM (296.8 cm3 versus 151.4 cm3, P < 0.001) though final implant size was comparable in both cohorts (P = 0.584). There was no significant difference in the rate of any complication between the ADM and no ADM cohorts (25.7% versus 17.1%, respectively P = 0.357), including major mastectomy flap necrosis (P = 0.245), major infection (P = 1.000), seroma (P = 0.620), expander explantation (P = 1.000), capsular contracture (P = 1.000), implant dystopia (P = 1.000), and rippling (P = 0.362).Conclusions:Immediate two-stage prepectoral breast reconstruction with tissue expanders has comparable rates of short-term complications with or without ADM support. Safety of prepectoral expander placement without ADM may warrant more selective ADM use in these cases.
