Impact of Radiation on Implant-Based Breast Reconstruction in Prepectoral Versus Submuscular Planes.

BACKGROUND: Postmastectomy implant-based breast reconstruction (IBR) in the setting of radiation (XRT) comes with a high risk of perioperative complications regardless of reconstruction method. The aim of study was to identify the effects of XRT on IBR using a prepectoral versus submuscular approach. METHODS: A retrospective chart review was performed after institutional review board approval was obtained. Patients at a single institution who had 2-stage IBR from June 2012 to August 2019 were included. Patients were separated into 4 groups: prepectoral with XRT (group 1), prepectoral without XRT (group 2), submuscular with XRT (group 3), and submuscular without XRT (group 4). Patient demographics, comorbidities, and postoperative complications were recorded and analyzed. RESULTS: Three hundred eighty-seven breasts among 213 patients underwent 2-stage IBR. The average age and body mass index were 50.10 years and 29.10 kg/m2, respectively. One hundred nine breasts underwent prepectoral reconstruction (44 in group 1, 65 in group 2), and 278 breasts underwent submuscular reconstruction (141 in group 3, 137 in group 4). Prepectoral tissue expander placement was associated with higher complication rates in the radiated group (38.6% compared with 34.0% submuscular) and lower complication rates in the nonradiated group (26.2% compared with 29.2% submuscular), although significantly less explants were performed in prepectoral group, regardless of XRT status. The 3 most common complications overall were contracture (15.1% radiated, 10.4% nonradiated), infection (18.4% radiated, 11.9% nonradiated), and seroma (15.7% radiated, 10.9% nonradiated). CONCLUSIONS: Two-stage, prepectoral tissue expander placement performs clinically better than submuscular in nonradiated patients compared with radiated patients; however, no statistical significance was identified. Prepectoral had a significantly less incidence of reconstructive failure than submuscular placement regardless of XRT status. Future larger-scale studies are needed to determine statistically significant difference in surgical approach.

Single-Institution Experience With Component Separation for Ventral Hernia Repair: A Retrospective Review.

PURPOSE: In this study, we reviewed our institution's experience using component separation for repair of ventral hernias. METHODS: This was a retrospective review of all component separations for ventral hernia between July 2009 and December 2015. Recorded data included body mass index (BMI), preoperative albumin, smoking history, comorbidities, additional procedures, length of surgery, hospitalization, recurrence, and postoperative complications. RESULTS: One hundred ninety-six component separations were performed in the study period. The average patient age was 56 years, and 65.3% of patients were female. The average BMI was 32.6 kg/m; preoperative albumin was 3.59; 18.4% were current smokers; 28.1% were diabetic; and 14.3% had heart disease. Postoperative complications developed in 16.8% of patients. Recurrence developed in 8.7% of patients. Patients who developed a postoperative complication had a higher BMI (P = 0.025) and lower albumin (P = 0.047) compared with patients who did not develop complications. Current smokers were more likely to develop complications (P = 0.008). More than one third of patients had additional procedures at the time of the ventral hernia repair. The addition of a plastic surgery procedure was not associated with an increased risk of developing a complication (P = 0.25). Patients who developed complications had a significantly longer hospital course (P < 0.001) but no difference in total operative time (P = 0.975). Increased number of comorbidities did not statistically correlate with an increased complication rate (P = 0.65) or length of hospital stay (P = 0.43). CONCLUSIONS: We identified risk factors that increase the likelihood of postoperative complications and length of hospital stay. In addition, this study suggests that more comorbidities and additional procedures at the time of the hernia repair may not have as large of impact on complication risk as previously thought.

Ketorolac and Hematoma Incidence in Postmastectomy Implant-Based Breast Reconstruction.

BACKGROUND: Ketorolac tromethamine (Toradol) is an effective a nonsteroidal anti-inflammatory drug and a powerful analgesic for patients undergoing breast surgery. However, the potential for postoperative bleeding has not yet been explored specifically in women undergoing implant-based breast reconstruction. There is concern that an increased risk of bleeding exists in this population due to the lack of tissue apposition as a result of implant placement. We therefore seek to assess the associated risk of bleeding complication in implant-based breast reconstruction at our academic institution. To the best of our knowledge, this represents the first case series addressing safety profile of Toradol specifically in patients undergoing nonautologous, implant-based breast reconstruction. METHODS/RESULTS: A single-center, retrospective review was performed analyzing our institutional experience with Toradol in nonautologous, implant-based breast reconstruction following mastectomy. A prospective database of 522 patients collected between 2008 and 2013 was analyzed. Within the database, 57 patients who received intraoperative ketorolac were identified among a total of 180 patients undergoing prosthetic reconstruction. No statistically significant difference was found in the incidence of clinically relevant hematoma formation between the control and Toradol groups. The frequency of hematoma formation in the control was 0.09 (11/123 patients, 95% confidence interval = 0.05-0.15) and 0.04 in the Toradol group (2/57 patients, 95% confidence interval = 0.01-0.12), resulting in a P value of 0.32. Regarding the secondary outcomes, we did not detect a statistically significant difference in the total number of complications or length of hospital stay in the Toradol and control groups. CONCLUSIONS: Review of our breast reconstruction database did not find a trend toward an elevated incidence of hematoma associated with intraoperative Toradol use in implant-based postmastectomy reconstruction.

Robotic-assisted deep inferior epigastric artery perforator flap abdominal harvest for breast reconstruction: A case report.

The deep inferior epigastric perforator (DIEP) flap is a mainstay of autologous breast reconstruction. The da Vinci robot has recently been adapted for an increasing number of reconstructive surgeries. The literature has yet to describe its use for the intra-abdominal harvest of the deep inferior epigastric vessels (DIEV) during DIEP flap breast reconstruction. We show the use of the da Vinci robotic surgical system for the intra-abdominal dissection of DIEV during delayed breast reconstruction with a DIEP flap in a 51-year-old female who had undergone a right modified radical mastectomy. After dissecting the flap from the anterior abdominal wall leaving only the targeted perforating vessels intact, a 1.5 cm fascial incision was made adjacent to the perforator and the vessels were dissected to below the level of the fascia. The intra-abdominal robotic-assisted dissection of the DIEV up to the perforator was then completed. The DIEV were divided at their origin using the robot and the flap removed from the abdomen for subsequent reconstruction. This technique enabled improved precision of flap harvest while also decreasing the donor-site morbidity by minimizing the incision length of the anterior rectus sheath. The patient had an uneventful postoperative course and, at 9-month follow-up, exhibited no evidence of flap or donor-site complications, specifically hernia or bulge. This novel approach for the harvest of a DIEP flap introduces an alternative technique to the conventional DIEP flap procedure in the appropriate patient population. Risks inherent to this technique as well as additional costs must be considered.
