Article Synopsis
  • The study investigates the effectiveness of two surgical techniques (Wise pattern vs. modified vertical technique) for post-mastectomy reconstruction in patients with severe breast ptosis.
  • It highlights that while both methods had similar BMI among patients, the Wise pattern showed a higher incidence of complications, such as seroma and skin necrosis.
  • The findings suggest that the vertical pattern might be a safer and simpler option for certain patients, potentially reducing the risk of complications.

Inflammatory breast carcinoma (IBC) is an aggressive form of breast cancer involving skin lymphatics. Breast reconstruction traditionally has been delayed in IBC. Immediate reconstruction has been described in select patients.

Breast cancer-related lymphedema is characterized by progressive limb enlargement and occurs in up to 30% of breast cancer patients following axillary lymph node dissection (ALND). Immediate lymphatic reconstruction (ILR) is a preventative technique used to reduce lymphedema rates by performing lymphovenous anastomoses of disrupted afferent lymphatics. This study presents a novel method of axillary reconstruction following ALND using a buried dermal flap that provides local tissue with intact subdermal lymphatics to the axillary dead space.

Background: Implant infection is problematic in breast reconstruction. Traditionally, infected tissue expanders (TE)/implants are removed for several months before replacement, resulting in breast reconstruction delay. Salvage involving device removal, negative pressure wound therapy with instillation and dwell (NPWTi-d) placement, and early staged TE/implant replacement within a few days has been described.

Infection after implant-based breast reconstruction remains challenging, with infection rates up to 24%. Best clinical practice indicates prophylactic oral antibiotics are ineffective at preventing infection. Absorbable antibiotic beads have been routinely used in other surgical subspecialties such as orthopedic and vascular procedures for continuous local antibiotic delivery to the surgical site when implants are placed.

Background:  Lymphedema can occur in patients undergoing axillary lymph node dissection (ALND) and radiation for breast cancer. Immediate lymphatic reconstruction (ILR) is performed to decrease the risk of lymphedema in patients after ALND. Some patients who ultimately require ALND are candidates for attempted sentinel lymph node biopsy (SLNB) or targeted axillary excision.

Background and objective Immediate lymphatic reconstruction (ILR) is emerging as a useful adjunct after axillary lymph node dissection (ALND), leading to a decrease in lymphedema rates from 30 to 3-13% in breast cancer patients. ILR requires coordination between two surgical specialties for oncologic ALND and microsurgical axillary lymphatic anastomosis. This study aimed to assess the trends in the frequency of ILR performed after ALND at our institution.

Background And Purpose: Within, we compare the short-term outcomes of patients receiving same day mastectomy and tissue expander reconstruction for those discharged on postoperative day one versus those discharged immediately following surgery to explore the safety, efficacy, and potential impact on hospital processes.

Methods: This was a retrospective review of patients undergoing mastectomy with immediate TE reconstruction from March 2019 to March 2021. Patients were stratified into two cohorts; observation overnight (OBS), and discharge on same day of surgery (DC).

Deep inferior epigastric perforator (DIEP) flaps are becoming the most frequent choice for autologous breast reconstruction. There are many benefits to DIEP flaps, but the procedures can be lengthy and have a steep learning curve. The balance of efficiency and education can be difficult to achieve.

Infections are problematic in postmastectomy implant-based reconstruction with infection rates as high as 30%. Strategies to reduce the risk of infection have demonstrated various efficacies. A prolonged course of systemic, oral antibiotics has not shown evidence-based benefit.

Summary: Staged implant-based breast reconstruction with immediate tissue expanders (TEs) is the most common method of breast reconstruction after mastectomy. TEs traditionally are filled with saline for expansion. Some surgeons have advocated initial intraoperative fill of the TE with air to avoid excess pressure on ischemic mastectomy skin flaps.

Background:  Microsurgical techniques have a steep learning curve. We adapted validated surgical approaches to develop a novel, competency-based microsurgical simulation curriculum called Fundamentals of Microsurgery (FMS). The purpose of this study is to present our experience with FMS and quantify the effect of the curriculum on resident performance in the operating room.

Background: Breast pocket irrigation with antiseptic solutions is performed to reduce contamination with breast implants. The optimal antiseptic irrigation solution and the efficacy of individual practices are unclear. Oxychlorosene sodium is frequently used at our institution.

Introduction: Smoking is a risk factor for post-operative complications following breast reconstruction. Abruptly refraining from all nicotine products may be difficult for patients with a new cancer diagnosis. The goal of this study is to assess complications following a distinct approach to tissue expander reconstruction in nicotine users.

Unlabelled: Patients undergoing free flap breast reconstruction are at a high risk for venous thromboembolism based upon Caprini scores. Guidelines for venous thromboembolism prophylaxis recommend high-risk groups receive extended chemoprophylaxis for several weeks after gynecological, orthopedic, and surgical oncology cases. Extended prophylaxis has not been studied in free flap breast reconstruction.

Background:  Deep inferior epigastric artery perforator (DIEP) flap is a common method of breast reconstruction. Enhanced recovery after surgery (ERAS) postoperative protocols have been used to optimize patient outcomes and facilitate shorter hospital stays. The effect of patient expectations on length of stay (LOS) after DIEP has not been evaluated.

Background:  Transcutaneous tissue oximetry is widely used as an adjunct for postoperative monitoring after microvascular breast reconstruction. Despite a high sensitivity at detecting vascular issues, alarms from probe malfunctions/errors can generate unnecessary nursing calls, concerns, and evaluations. The purpose of this study is to analyze the false positive rate of transcutaneous tissue oximetry monitoring over the postoperative period and assess changes in its utility over time.

Background: Patients with hormone receptor-positive breast tumors receive hormonal therapy with either selective estrogen receptor modulators (SERMs) (eg, tamoxifen) or aromatase inhibitors (AIs) (eg, anastrozole) for 5 to 10 years. Patients are using these therapies frequently during breast reconstruction. Literature investigating the effects of hormonal modulators on breast reconstruction outcomes demonstrates conflicting results.

Background:  Sarcopenia is a condition characterized by the loss of skeletal muscle mass and strength. Recently, there has been a tremendous amount of research into the prognostic value of sarcopenia in surgical outcomes. The purpose of this study was to compare postoperative outcomes in free flap breast reconstruction in patients with and without sarcopenia.

In 2009, 86,424 breast reconstructions were performed in the United States, with 76% being implant-based procedures. Capsular contracture and infection are the 2 most cited indications for implant explantation, resulting in a reconstruction failure. However, several patients are dissatisfied with implant reconstruction even without the aforementioned complications.
