Background: In transgender or non-binary patients (TGNB) with failed penile inversion vaginoplasty (PIV), peritoneal flap vaginoplasty (PFV) and intestinal segment vaginoplasty (ISV) facilitate restoration of neovaginal depth and sexual function. This study compared the outcomes of revision PFV and ISV in TGNB patients with failed PIV., Methods: TGNB patients who underwent secondary PFV or ISV from December 2018 to April 2023 were reviewed., Results: Twenty-one (5.8%) patients underwent secondary PFV and 24 (6.6%) underwent secondary ISV, due to vaginal stenosis (n = 45, 100.0%). Mean duration to first successful dilation and average vaginal depth were comparable between the groups. Seven (33.3%) PFV patients experienced short-term complications, including introital dehiscence (n = 2, 9.5%), vaginal stenosis (n = 2, 9.5%), vaginal bleeding (n = 2, 9.5%), and reoperation (n = 2, 9.5%). Nine (42.9%) experienced long-term complications, including urethrovaginal fistula formation (n = 2, 9.5%), hypergranulation (n = 2, 9.5%), vaginal stenosis (n = 7, 33.3%), and reoperation (n = 6, 28.6%). Ten (41.7%) ISV patients experienced short-term complications, including dehiscence (n = 4, 19.0%), ileus (n = 2, 8.3%), introital stenosis (n = 2, 9.5%), and reoperation due to vaginal bleeding (n = 2, 8.3%). Six (25.0%) experienced long-term complications, including introital stenosis (n = 3, 12.5%), mucosal prolapse (n = 2, 8.3%), and reoperation due to mucosal prolapse (n = 4, 16.7%). Secondary PFV had a higher rate of vaginal stenosis (p = 0.003). There were no cases of partial or full-thickness flap necrosis., Conclusion: Revision PFV and ISV represent viable techniques for addressing vaginal stenosis secondary to PIV. Although PFV and ISV had comparable rates of short-term complications, ISV demonstrated a lower incidence of recurrent vaginal stenosis, which may inform operative decision-making., (Copyright © 2024 British Association of Plastic, Reconstructive and Aesthetic Surgeons.

Fillet of toe flap (FTF) leverages the "spare parts" algorithm in reconstructive surgery-utilizing tissue from amputated or otherwise non-salvageable body parts, thus avoiding donor-site morbidity. This study assesses the efficacy of FTF coverage in non-traumatic foot amputations. A retrospective review of patients undergoing foot amputation with FTF coverage between January 2013 to August 2023 was conducted. Patient characteristics, operative details, and outcomes were collected. Primary outcome was FTF survival (no necrosis ≤7 days postoperatively). Secondary outcome was acute complications (≤42 days postoperatively). A total of 70 patients were included. Mean age was 65.0±13.7 years. Median Charlson Comorbidity Index was 6.0 (interquartile range [IQR]: 4.0-7.0). The most common wound location was the hallux (n=34). In 45 (64.2 %) patients with preoperative angiography, the patency rates were: first dorsal metatarsal artery (n=10, 22.2 %), lateral plantar artery (n=7, 15.6 %), medial plantar artery (n=6, 13.3 %), and dorsalis pedis artery (n=4, 8.9 %). Mean follow-up duration was 9.0 (IQR: 32) months. Fifteen (21.4 %) patients experienced at least one acute complication: deep surgical site infection (SSI; i.e., abscess, gangrenous necrosis; n=13, 18.6 %) and cellulitis (n=7, 10.0 %). Eleven (15.7 %) patients required reoperation for debridement (n=4, 5.7 %), wound closure (n=4, 5.7 %), flap necrosis (n=3, 4.3 %), incision and drainage (n=1, 1.4 %), split-thickness skin grafting (n=1, 1.4 %), and foreign body exploration (n=1, 1.4 %). FTF survival was 94.2 % (n=66). FTF facilitates reconstruction in complex cases and should be integrated into each chronic LE wound algorithm to avoid additional donor-site morbidity, and to facilitate stump-length preservation or limb salvage., Competing Interests: Declaration of competing interest The authors have no conflicts of interest to declare., (Copyright © 2024.

Background: Local flaps remain a valuable reconstructive tool as a means for limb salvage for patients with advanced arterial disease. Our single-center, retrospective cohort study aims to compare the outcomes of different patterns of blood flow affected by vascular disease to pedicles in local flap reconstruction of the foot and ankle., Methods: A retrospective review of 92 patients and 103 flaps was performed. On angiograms, pattern of blood flow to the flap pedicle was determined to be direct inline flow (DF) or indirect flow (IF). Patterns of IF were either by arterial-arterial connections (AC) or unnamed randomized collaterals (RC). Primary outcomes were immediate flap success and limb salvage. Comparative analyses were performed using the χ2 and Fisher tests for categorical variables., Results: Among all flaps, 73.8% (n = 76/103) had DF and 26.2% (n = 27/103) had IF. Both groups experienced similar rates of immediate flap success (DF = 97.3% vs IF = 92.6%, P = 0.281) and limb salvage (DF = 75.% vs IF = 66.7%, P = 0.403). However, the rate of contralateral amputation was significantly higher in the IF group (26.9% vs 5.3%, P = 0.006). When comparing the 3 distinct patterns of blood flow (DF vs AC vs RC), pedicled flaps were more commonly supplied by DF and AC, while random pattern flaps were more commonly supplied by RC (P = 0.042)., Conclusions: Alternative routes of revascularization can maintain local flap viability and achieve similar rates of limb salvage but risks contralateral amputation. We found that pedicled and local muscle flaps require inline blood flow or blood supply by ACs. Meanwhile, random pattern flap can be supported by random collaterals., Competing Interests: Conflicts of interest and sources of funding: none declared., (Copyright © 2024 Wolters Kluwer Health, Inc.

Background: The surgical decision for limb-salvage with free tissue transfer (FTT), partial foot amputation (PFA), or below-knee amputation (BKA) for complex lower extremity (LE) wounds hinges on several factors, including patient choice and baseline function. However, patient-reported outcome measures (PROMs) on LE function, pain, and QoL for chronic LE wound interventions are limited. Thus, the study aim was to compare PROMs in patients who underwent FTT, PFA, or BKA for chronic LE wounds., Methods: PROMs were collected via QR code for all adult chronic LE wound patients who presented to a tertiary wound center between June 2022 and June 2023. A cross-sectional analysis of patients who underwent FTT, PFA, or BKA was conducted. The 12-Item Short Survey (SF-12), PROM Information System Pain Intensity (PROMIS-3a), and Lower Extremity Functional Scale (LEFS) were completed at 1, 3, and 6 months and 1, 3, and 5 years postoperatively. Patient demographics, comorbidities, preoperative characteristics, and amputation details were collected., Results: Of 200 survey sets, 71 (35.5%) underwent FTT, 51 (25.5%) underwent PFA, and 78 (39.0%) underwent BKA. Median postoperative time points of survey completion between FTT (6.2 months, IQR: 23.1), PFA (6.8 months, IQR: 15.5), and BKA (11.1 months, IQR: 21.3) patients were comparable (P = 0.8672). Most patients were male (n = 92, 76.0%) with an average age and body mass index (BMI) of 61.8 ± 12.6 years and 30.3 ± 7.0 kg/m2, respectively. Comorbidities for FTT, PFA, and BKA patients included diabetes mellitus (DM; 60.6% vs 84.2% vs 69.2%; P = 0.165), peripheral vascular disease (PVD; 48.5% vs 47.4% vs 42.3%; P = 0.790), and chronic kidney disease (CKD; 12.1% vs 42.1% vs 30.8%; P = 0.084). No significant differences were observed between FTT, PFA, and BKA patients in mean overall PROMIS-3a T-scores (49.6 ± 14.8 vs 54.2 ± 11.8 vs 49.6 ± 13.7; P = 0.098), LEFS scores (37.5 ± 18.0 vs 34.6 ± 18.3 vs 38.5 ± 19.4; P = 0.457), or SF-12 scores (29.6 ± 4.1 vs 29.5 ± 2.9 vs 29.0 ± 4.0; P = 0.298)., Conclusion: Patients receiving FTT, PFA, or BKA for chronic LE wounds achieve comparable levels of LE function, pain, and QoL postoperatively. Patient-centered functionally based surgical management for chronic LE wounds using interdisciplinary care, preoperative medical optimization, and proper patient selection optimizes postoperative PROMs., Competing Interests: Conflicts of interest disclosures: The authors have no conflicts of interest to declare., (Copyright © 2024 Wolters Kluwer Health, Inc.

Background: Patients with nonhealing lower extremity (LE) wounds often require a split-thickness skin graft (STSG) for closure. Nonviable tissue must be debrided before STSG inset. Our study aimed to compare differences in debridement depth on STSG outcomes., Methods: Chronic, atraumatic LE wounds receiving STSG from December 2014 to December 2022 at a single institution were reviewed. Demographics, wound characteristics, operative details, and outcomes were collected. Superficially debrided wounds were compared with wounds receiving deep debridement (DD), defined by debriding to the level of white tissue underlying the granulation tissue. Subanalysis was performed on wounds that had a negative and positive postdebridement culture. Primary outcome was graft failure., Results: Overall, 244 wounds in 168 patients were identified. In total, 158 (64.8%) wounds were superficially debrided and 86 (35.3%) received DD. The cohort had a median Charlson Comorbidity Index of 4 [interquartile range (IQR): 3]. Diabetes (56.6%) and peripheral artery disease (36.9%) were prevalent. The only statically significant demographic difference between groups was congestive heart failure (SD: 14.9% versus DD: 3.0%, P = 0.017). Wound size, depth, and all microbiology results were similar between groups. Postoperatively, the DD group demonstrated significantly less graft failure (10.5% versus 22.2%, P = 0.023). In a multivariate regression, DD was independently associated with lower odds of graft failure (OR: 0.0; CI, 0.0-0.8; P = 0.034). Sub-analysis of graft failure supported this finding in culture-positive wounds (DD: 7.6% versus DD: 22.1%, P = 0.018) but not in culture-negative wounds (13.6% versus 22.2%, P = 0.507)., Conclusions: The DD technique demonstrates improved outcomes in chronic, culture-positive LE wounds receiving STSG., Competing Interests: The authors have no financial interest to declare in relation to the content of this article., (Copyright © 2024 The Authors.

Background: The use of free tissue transfer (FTT) is efficacious for chronic, non-healing lower extremity (LE) wounds. The four pillars of managing patient comorbidities, infection control, blood flow status, and biomechanical function are critical in achieving successful limb salvage. The authors present their multidisciplinary institutional experience with a review of 300 FTTs performed for the complex LE limb salvage of chronic LE wounds. Methods: A single-institution, retrospective review of atraumatic LE FTTs performed by a single surgeon from July 2011 to January 2023 was reviewed. Data on patient demographics, comorbidities, preoperative management, intraoperative details, flap outcomes, postoperative complications, and long-term outcomes were collected. Results: A total of 300 patients who underwent LE FTT were included in our retrospective review. Patients were on average 55.9 ± 13.6 years old with a median Charlson Comorbidity Index of 4 (IQR: 3). The majority of patients were male (70.7%). The overall hospital length of stay (LOS) was 27 days (IQR: 16), with a postoperative LOS of 14 days (IQR: 9.5). The most prevalent comorbidities were diabetes (54.7%), followed by peripheral vascular disease (PVD: 35%) and chronic kidney disease (CKD: 15.7%). The average operative LE FTT time was 416 ± 115 min. The majority of flaps were anterolateral thigh (ALT) flaps (52.7%), followed by vastus lateralis (VL) flaps (25.3%). The immediate flap success rate was 96.3%. The postoperative ipsilateral amputation rate was 12.7%. Conclusions: Successful limb salvage is possible in a highly comorbid patient population with a high prevalence of diabetes mellitus, peripheral vascular disease, and end-stage renal disease. In order to optimize patients prior to their LE FTT, extensive laboratory, arterial, and venous preoperative testing and diabetes management are needed preoperatively. Postoperative monitoring and long-term follow-up with a multidisciplinary team are also crucial for long-term limb salvage success.
