Introduction: Reducing donor site morbidity after deep inferior epigastric artery perforator (DIEP) flap harvest relies mainly upon maintaining integrity of the anterior rectus sheath fascia. The purpose of this study is to describe our minimally-invasive technique for robotic DIEP flap harvest., Methods: A retrospective review of four patients undergoing seven robotic-assisted DIEP flaps from 2019 to 2020 was conducted. Average patient age and BMI were 52 years (range: 45-60 years) and 26.7 kg/m 2 (range: 20.6-32.4 kg/m 2 ), respectively. Average follow-up was 6.31 months (range: 5.73-7.27 months). Robotic flap harvest was performed with intramuscular perforator dissection in standard fashion, followed by the transabdominal preperitoneal (TAPP) approach to DIEP pedicle harvest using the da Vinci Xi robot. Data was collected on demographic information, perioperative characteristics. Primary outcomes included successful flap harvest as well as donor site morbidity (e.g., abdominal bulge, hernia, bowel obstruction, etc.)., Results: All four patients underwent bilateral abdominally-based free flap reconstruction. Three patients received bilateral robotic DIEP flaps, and one patient underwent unilateral robotic DIEP flap reconstruction. The da Vinci Xi robot was used in all cases. Average flap weight and pedicle length were 522 g (range: 110-809 g) and 11.2 cm (range: 10-12 cm), respectively. There were no flap failures, and no patient experienced abdominal wall donor site morbidity on physical exam., Conclusion: While further studies are needed to validate its use, this report represents the largest series of robotic DIEP flap harvests to date and is a valuable addition to the literature., (© 2022 Wiley Periodicals LLC.)

We describe the use of the medial sural artery musculocutaneous perforator (MSAP) flap at our institution. It is a relatively new flap, originally described in 2001 for lower extremity defects, that has become increasingly popular for head and neck reconstruction due to its versatility, thinness, pliability, long pedicle, and particularly favorable donor site. It has been described for reconstruction of oral defects, but there is little published on its use in pharyngeal reconstruction. We suggest that the MSAP is an ideal flap for addressing defects caused by pharyngoesophageal stenosis, pharyngeal fistulas, or laryngopharyngectomies. We review 5 cases at our institution from June 2016 to November 2017.

Background:  Transversus abdominis plane (TAP) blocks have been shown to significantly reduce pain and narcotic consumption following major abdominal surgeries. This study investigates the literature on their use in microsurgical breast reconstruction., Patients and Methods:  A systematic review of TAP blocks in autologous breast reconstruction was performed., Results:  Across 10 included studies, 174 patients (5 studies) received an intraoperative TAP block injection, 185 patients (4 studies) received a TAP catheter for intermittent postoperative analgesia, and 325 patients served as controls for a total of 684 included patients. The majority of TAP block delivery techniques were ultrasound guided (7/10 studies). Liposomal bupivacaine (LB) was the most commonly used analgesic (4 studies and139 patients) followed by conventional bupivacaine (3 studies and 105 patients). Eight studies found a significant reduction in oral, intravenous, and/or total morphine requirements in the TAP group when either the daily average and/or total inpatient consumption was compared with the control. Hospital length of stay was significantly shorter for patients undergoing single intraoperative TAP block injection with any analgesic as compared with standard narcotic-based protocols (mean difference= -0.95 days; 95% CI: -1.72 to -0.17 days; p  = 0.02). Looking at TAP blocks specifically with LB, there was a mean decrease of 0.83 days as compared with the control, which was not statistically significant (95% CI: -1.90 to 0.25 days; p  = 0.13)., Conclusion:  While the current data support the use of TAP blocks in autologous breast reconstruction, additional studies with more standardized protocols should be performed to determine the most optimal practice., Competing Interests: None declared., (Thieme Medical Publishers 333 Seventh Avenue, New York, NY 10001, USA.)

Objectives: The medial sural artery perforator (MSAP) free flap is an uncommonly utilized soft tissue flap in head and neck reconstruction. It is a thin, pliable, fasciocutaneous flap that provides significant pedicle length. The donor site can be closed primarily, and its location is more aesthetically pleasing to patients. We aim to describe the MSAP flap and compare it to other commonly used free flaps in the head and neck., Study Design: Retrospective case series., Methods: A retrospective review of all MSAP cases performed at New York University Langone Health was performed from July 2016 to November 2017. We examined the patients' age, diagnosis, history of prior radiation therapy, and comorbidities, as well as flap-specific information and recipient site., Results: Twenty-one patients underwent a variety of different head and neck procedures with coverage using an MSAP flap. Recipient sites included tongue, cheek, soft and hard palate, cervical esophagus, and pharynx. Pedicle length ranged from 8 cm to 12 cm. The smallest surface area harvested was 24 cm 2 (6 cm × 4 cm), and the largest was 120 cm 2 (15 cm × 8 cm). The flaps ranged from 5 to 12 mm in thickness. Venous coupler size ranged from 2.0 to 3.5 mm. Primary closure of the donor site was achieved in 18 of 21 flaps. Twenty of 21 flaps were transferred successfully., Conclusion: The MSAP flap is a highly versatile and reliable option for a thin, pliable soft tissue flap with a donor site that may be preferable over the radial forearm free flap and anterolateral thigh flap in complex head and neck reconstruction., Level of Evidence: 4 Laryngoscope, 129:1330-1336, 2019., (© 2018 The American Laryngological, Rhinological and Otological Society, Inc.)

Background: The medial sural artery perforator flap offers thin, pliable tissue with a relatively long pedicle and low donor-site morbidity. This study explores the characteristics and uses of the medial sural artery perforator flap along with postoperative outcomes and complications., Methods: A systematic literature review was performed using PubMed, Embase, and Cochrane Central Register of Controlled Trials to identify all cases of medial sural artery perforator flap reconstruction. Descriptive and meta-analyses were performed on pooled outcomes. Multivariate logistic regression identified factors associated with increased complication rates., Results: Thirty-five studies encompassing 526 medial sural artery perforator flaps were included for analysis. The most common reasons for surgery were oncologic (47.6 percent) and traumatic injuries (31.8 percent). The oral cavity was the most common recipient location (45.5 percent). Average flap dimensions were 6.0 ± 2.3 cm × 9.8 ± 3.6 cm, with an average pedicle length of 10.1 ± 6.6 cm. Meta-analysis revealed an overall complication rate of 14.3 percent (Q value = 22.16; p = 0.877; I(2)= -39.9). Use of chimeric medial sural artery perforator flaps was associated with significantly higher rates of complications (OR, 3.92; p = 0.039; 95 percent CI, 1.10 to 13.89). The majority of flap donor sites were closed primarily (68 percent) versus 32 percent that were covered with split-thickness skin grafts. A flap width greater than 5.75 cm had an odds ratio of 5.3 (95 percent CI, 1.3 to 21.8; p = 0.014) of having a donor-site complication if closed primarily., Conclusions: The medial sural artery perforator flap offers thin, pliable tissue with a relatively long pedicle and has minimal donor-site morbidity when the donor site is managed appropriately. As such, it should be considered a workhorse flap for both head and neck and extremity reconstruction.
