Abstract Background Two-stages pre-pectoral breast reconstruction may confer advantages over direct to implant (DTI) and subpectoral reconstruction in selected patients who have no indication for autologous reconstruction. The primary endpoint of the study was to evaluate and compare the incidence of capsular contracture in the pre-pectoral two-stages technique versus the direct to implant technique. Complications related to the two surgical techniques and patient satisfaction were also evaluated. Methods A retrospective review of 45 two stages and 45 Direct-to-implant, DTI patients was completed. Acellular dermal matrix was used in all patients. An evaluation of anthropometric and clinical parameters, surgical procedures and complications was conducted. Minimum follow-up was 12 months after placement of the definitive implant. Results There was no statistically significant difference in the rate of capsular contracture in the two groups. Rippling occurred more in DTI reconstruction. In the two-stages reconstruction, lipofilling was applied more often and there was a higher incidence of seroma. Patient satisfaction extrapolated from the Breast Q questionnaire was better for patients submitted to two-stage implant-based breast reconstruction. Conclusion Dual-stage pre-pectoral reconstruction with acellular dermal matrix appears to be a good reconstructive solution in patients with relative contraindications for one-stage heterologous reconstruction with definitive prosthesis and no desire for autologous reconstruction.

Innovative approaches to reconstruction have ushered in an era of breast reconstruction in which direct-to-implant procedures can provide an immediately reconstructed breast. Balancing the benefits against its technical challenges is vital. The authors evaluated the safety and efficacy of using direct-to-implant versus conventional two-stage reconstruction through a systematic meta-analysis.A literature search identified all articles published after 1999 involving prosthetic-based breast reconstruction as a two-stage tissue expander/implant or direct-to-implant technique. The primary outcomes of interest, including implant loss, capsular contracture, reoperation, and infection, were analyzed by means of head-to-head meta-analysis.Thirteen studies involving 5216 breast reconstructions were included. The average patient age was 47.2 ± 1.0 years, the average body mass index was 24.9 ± 0.8 mg/k2, and the average follow-up was 40.8 months. Wound infection, seroma, and capsular contracture risk were similar between groups. However, direct-to-implant reconstruction was associated with a higher risk for skin flap necrosis (OR, 1.43; p = 0.01; I2 = 51 percent) and reoperation (OR, 1.25; p = 0.04; I2 = 43 percent). Ultimately, the risk for implant loss was nearly two-fold higher with direct-to-implant reconstruction compared with tissue expander/implant reconstruction (OR, 1.87; p = 0.04; I2 = 33 percent).Although direct-to-implant and two-stage tissue expander/implant reconstruction are successful approaches, this meta-analysis demonstrates significantly greater risk of flap necrosis and implant failure with direct-to-implant reconstruction. The authors' findings suggest that the critical component of patient selection is judgment of mastectomy flap tissue quality. These findings can enhance the risk counseling process and highlight the need for additional investigations to optimize outcomes.

Background: Postmastectomy radiation therapy is increasingly indicated in patients with node-positive breast cancer. The authors prospectively evaluated long-term outcomes in patients with two-stage implant-based reconstruction and postmastectomy radiation therapy to the permanent implant. Methods: A cohort of 1415 patients operated on by a single surgeon from 1998 to 2010 was evaluated annually. Outcomes were recorded prospectively. Complication rates were compared between irradiated and nonirradiated implants, including reconstructive failure (implant loss), complications (e.g., capsular contracture), aesthetic results, and satisfaction. Predicted implant loss and replacement rates were examined by irradiation status with Kaplan-Meier analysis and the log-rank test. Results: A total of 2133 breast implant reconstructions with a mean follow-up of 56.8 months (range, 12 to 164 months) were included. Three hundred nineteen implants received radiation. Implant loss occurred in 9.1 percent of irradiated implants and 0.5 percent of nonirradiated implants (p < 0.01). Capsular contracture grade IV was present in 6.9 percent of irradiated and 0.5 percent of nonirradiated implants (p < 0.01). There was no difference between groups regarding implant replacement. Ninety-two percent of irradiated patients had good to excellent aesthetic result, and 94.2 percent would choose implants again. Predicted implant loss rates were 17.5 percent and 2.0 percent for irradiated and nonirradiated implants, respectively, at 12 years (p < 0.01), and predicted implant replacement rates were 12.7 percent and 8.8 percent, respectively, at 8 years (p = not significant). Conclusions: This is the largest prospective long-term outcomes evaluation in women with immediate tissue expander/implant reconstruction and postmastectomy radiation therapy. Most patients had a good to excellent aesthetic result and preserve their reconstruction at 12 years. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, III.

Complications and outcomes were monitored following the implantation of 1655 breast implants over a 15-year period. Smooth, polyurethane, and textured implants were used in a variety of clinical settings. The time course of capsular contracture was analyzed by the Kaplan-Meier method. Regardless of implant type or indication for surgery, the probability of contracture increased with time. Polyurethane-covered implants were associated with a significant reduction in the risk of contracture for at least 7 years following implantation. Smooth and textured silicone implants had contracture rates similar to each other, and the particular type of surface texturing (Biocel versus Siltex) was of no consequence. Contracture was more common following breast reconstruction and implant replacement than after augmentation mammaplasty and was not affected by filler material or implant size. Implant position did not alter the risk of contracture after augmentation; tissue expansion did not affect the risk of contracture after breast reconstruction. Infections were unusual but most common after reconstruction and unrelated to surface texture or filler material. Skin wrinkling was more frequent with saline implants and in the presence of surface texturing. Implant rupture was rare, with an incidence of 1 per 760 implant-years. Implant-associated connective-tissue disease was noted in only one individual, an incidence of 1 per 3801 implant-years.

Purpose. In modern breast cancer treatment, a growing role has been observed for breast reconstruction together with an increase in clinical indications for postmastectomy radiotherapy (PMRT). Choosing the optimum type of reconstructive technique is a clinical challenge. We therefore conducted a national multicenter study to analyze the impact of PMRT on breast reconstruction. Methods. We conducted a retrospective case-control multicenter study on women undergoing breast reconstruction. Data were collected from 18 Italian Breast Centres and stored in a cumulative database which included the following: autologous reconstruction, direct-to-implant (DTI), and tissue expander/immediate (TE/I). For all patients, we described complications and surgical endpoints to complications such as reconstruction failure, explant, change in type of reconstruction, and reintervention. Results. From 2001 to April 2020, 3116 patients were evaluated. The risk for any complication was significantly increased in patients receiving PMRT (aOR, 1.73; 95% CI, 1.33–2.24; ). PMRT was associated with a significant increase in the risk of capsular contracture in the DTI and TE/I groups (aOR, 2.24; 95% CI, 1.57–3.20; ). Comparing type of procedures, the risk of failure (aOR, 1.82; 95% CI, 1.06–3.12, ), explant (aOR, 3.34; 95% CI, 3.85–7.83, ), and severe complications (aOR, 2.54; 95% CI, 1.88–3.43, ) were significantly higher in the group undergoing DTI reconstruction as compared to TE/I reconstruction. Conclusion. Our study confirms that autologous reconstruction is the procedure least impacted by PMRT, while DTI appears to be the most impacted by PMRT, when compared with TE/I which shows a lower rate of explant and reconstruction failure. The trial is registered with NCT04783818, and the date of registration is 1 March, 2021, retrospectively registered.
