Abstract Abdominally based free flaps are commonly utilized in the context of breast reconstruction. Historically, postoperative care of these patients involved liberal amounts of intravenous fluid administration; however, overadministration of fluids puts patients at risk of developing flap edema via fluid shifts, electrolyte imbalances, wound dehiscence, and other sequelae. The purpose of this study is to assess fluid administration trends in this cohort at the authors' institution and assess its impact on patient outcomes. A retrospective review was performed on patients who underwent free-flap breast reconstruction. Patient demographics and hospitalization data were collected, and type of abdominal flap and reconstruction timing was noted. Perioperative fluid administration volumes were tracked, and primary outcomes included complication rate and type (e.g., acute blood loss anemia [ABLA], partial/total flap loss, etc.). Multivariable logistic regression was performed to assess the impact of fluid volume on patient outcomes. A total of 115 patients (mean age of 51.3 ± 10.5 years) underwent 188 abdominally based free flaps. Deep inferior epigastric artery perforator flaps were performed most often (n = 91), followed by muscle-sparing transverse rectus abdominis flaps (n = 88). Multivariable logistic regression demonstrated that high perioperative fluid administration (≥9,000 mL) was associated with increased odds of medical complications (odds ratio [OR] = 21.7; confidence interval [CI]: 5.54–84.5; p < 0.001). Patients with high fluid administration volumes experienced an increased (but nonstatistically significant) flap complication rate (OR = 2.96; CI: 0.89–9.88; p = 0.08) and developed ABLA at a higher rate (OR = 15.86; CI: 5.30–46.4; p < 0.001). High-volume resuscitation (≥9,000 mL) was associated with increased odds of ABLA as well as a greater likelihood of medical and flap complications in patients undergoing abdominally based free flaps for breast reconstruction. These data should be used to guide the development of protocols within institutions, which perform free flaps for breast reconstruction.

Abstract Robots have been used effectively in plastic and reconstructive surgery (PRS) for reconstruction. The utilization of robotics in all surgical specialties is expanding with the goal of offering the most appropriate patient-centered care possible, especially in complex multidisciplinary cases. Despite the safety, efficiency, and reproducibility of robotics in PRS, there is a paucity of required and formalized training in PRS residency programs. The ACGME and industry published guidelines were investigated. Robotic surgery case logs of Mayo Clinic Arizona General Surgery residents were analyzed with attention to equivalency certification (EQ). Over the past 5 years, the equivalency certification from Intuitive (Sunnyvale, CA) was obtained by 30% of all general surgery residents at our institution (range, 0–100). The case numbers to obtain the equivalence certification are industry recommendations, and proficiency is determined by the program director. The ACGME does not mandate robotics training in general surgery residency. According to the Society of American Gastrointestinal and Endoscopic Surgeons (SAGES), trainees must complete 20 console cases and 10 bedside cases to become industry certified. With respect to training and advancing the field, PRS residents could successfully obtain certification in their residency programs. The minimum case requirement recommended by SAGES is not burdensome and can ensure robotic privileges in PRS practice immediately following graduation. By improving the training for minimally invasive robotic surgery in plastic surgery, patients and healthcare systems benefit from improved quality of life outcomes and decreased postoperative length of stay, which results in less strain on our entire medical system.

Summary: Sacral reconstruction post tumor resection has historically been executed with the placement of hardware or free tissue transfer. Reconstruction using a vascularized bone graft is an alternative that avoids the complications associated with hardware placement or free tissue transfer. This article describes the first documented case of spinoplastic reconstruction using an iliac crest vascularized bone graft (IC-VBG) after the resection of a sacral ependymoma. This is a case of a 17-year-old boy with a history of a sacral myxopapillary ependymoma. He presented to a local emergency department complaining of 6 months of urinary incontinence and progressive paresthesias affecting the left lower extremity. Magnetic resonance imaging was significant for a lesion located in the extradural spinal canal. Biopsy confirmed a myxopapillary ependymoma, World Health Organization grade II. The initial intervention involved tumor resection with titanium hardware placement. He subsequently required replacement of the titanium hardware with carbon fiber, secondary to the need for surveillance imaging. He underwent harvesting and inset of the IC-VBG at the time of hardware replacement. IC-VBG is a safe and effective modality for spinoplastic reconstruction. It enhances the potential for solid bony union and offers a practical alternative to free bone transfer. This approach provides an asset to add to a reconstructive surgeon’s armamentarium, making it an essential tool for reconstructive surgeons working in conjunction with spinal surgery colleagues.

Abstract Background The presence of a chimeric gracilis and profunda artery perforator (PAP) flap with a common arterial pedicle has been demonstrated on computed tomography angiography in up to 59% of patients and confirmed in a cadaveric model. Already utilized for head and neck reconstruction by Heredero et al, this novel flap could provide more volume than either flap alone which is advantageous, particularly in patients with sizable defects. The purpose of this study was to determine the average tissue volume that can be utilized from this chimeric flap. Methods CT Angiogram imaging studies exhibiting chimeric flap anatomy were reviewed over a 7-year period at a single institution utilizing Visage Version 7.1, a radiology picture archiving and communication system. This software was used to trace the flap pedicles and to capture estimated soft tissue volumes of each respective flap. Results A total of 31 patients, consisting of 52 lower extremity gracilis and PAP chimeric flaps, underwent tissue volume analysis. The average total volume of soft tissue supplied by the gracilis flap was found to be 70.21 cm3 (standard deviation [SD] = 26.99). The average volume of the PAP flap was 31.73 cm3 (SD = 26.12). The average total volume captured by the chimeric gracilis and PAP flap was 101.94 cm3 (SD = 62.40). Conclusion The potential soft tissue volume that can be harvested from a chimeric gracilis and PAP flap is significantly greater than solitary gracilis or PAP flaps. This chimeric flap may serve as a viable and advantageous reconstructive option for patients requiring large volume soft tissue coverage, particularly if other sizable options are not available.
