Underwent Flap Reconstruction Research Articles

Comparisons of different general anesthetic techniques on immune function in patients undergoing flap reconstruction for oral cancer.

Anesthetic-induced immunosuppression is of particular interest in tumor surgery. This study aimed to investigate the influence of the 4 most common general anesthetic techniques on immune function in patients undergoing flap reconstruction for oral cancer. 116 patients were randomly divided into 4 groups. Patients in group S were given sevoflurane-based anesthesia. Group P was administered propofol-based anesthesia. The SD group received sevoflurane combined with dexmedetomidine anesthesia. The propofol combined with dexmedetomidine anesthesia (PD) group received PD. Blood samples were obtained at 5 time points: baseline (T0), 1 hour after the start of the operation (T1), end of the operation (T2), 24 hours (T3), and 48 hours (T4) after the operation. Lymphocyte subsets (including CD3+, CD4+, CD8+, and B lymphocytes) and dendritic cells were analyzed by flow cytometry. Blood glucose, norepinephrine, and cortisol levels were measured using ELISA and a blood gas analyzer respectively. In total, 107 patients were included in the final analysis. Immunological indicators, except CD8+ counts, were all decreased in groups S, P, and SD at T1-4 compared with the baseline value, and the counts of CD3+, CD4+, and dendritic cells, as well as CD4+/CD8+ ratios, were significantly higher in the PD group than in the S, P, and SD at T1-3 (P < .05). There were no significant differences between groups P and SD at any observation time point. Intraoperative stress indices, including norepinephrine and cortisol levels, were significantly lower in the PD group than in the other 3 groups at T1-2 (P < .05). These findings suggest that PD as a probably optimal choice can alleviate immunosuppression in patients undergoing flap reconstruction for oral cancer.

VRAM Versus ALT Flap Reconstruction for Large Head and Neck Defects: Does Weight Influence Complication Rate?

Background: Obesity remains a high-level risk factor for various cancers. Yet, some research has shown that higher BMIs may improve survival outcomes, particularly for head and neck squamous cell carcinoma (HNSCC). While this is a clear deviation from the norm, it raises the question of what other effects obesity may have on head and neck cancer patients, including surgical outcomes. Choosing the most appropriate flap for patients can be difficult for even experienced surgeons. Head and neck reconstructive surgeries are no exception to this rule and can be especially challenging. To produce the most favorable outcomes, a physician must be able to combine all flap attributes including donor and recipient site location, flap thickness, as well as each patient’s individual risk factors such as prior radiation. Purpose: The purpose of this study was to compare the outcomes of vertical rectus femoris myocutaneous (VRAM) and anterolateral thigh (ALT) flaps in overweight and obese individuals with varying head and neck cancers leaving large-sized defects to the outcomes in normal and underweight patients. Methods: A retrospective chart review was conducted of VRAM and ALT flaps performed over a period of 12 months at our university hospital for large head and neck reconstruction. Results: Of the 17 ALT patients, 80% (4/5) of the underweight patients, 57% (4/7) of the normal weight patients, 50% (1/2) of the overweight patients, and 33% (1/3) of the obese patients experienced complications. Of the 15 VRAM patients, 40% (2/5) of the underweight patients, 83% (5/6) of the overweight patients, and 50% (1/2) of the obese patients experienced complications. Conclusions: In our small sample size, a smaller percentage of obese patients with head and neck cancer who underwent flap reconstruction surgery had complications when undergoing ALT flaps than VRAM flaps, which contrasts with the normal and underweight patients, who had less complications with VRAM flaps than ALT flaps.

Comparison of instep and non-instep flap in the reconstruction of the weight-bearing portion of the forefoot and heel.

Instep flaps are commonly used for the reconstruction of weight-bearing areas of the foot. However, in cases of large defects or damage to the instep area, non-instep flaps such as reverse sural flaps (RSF) or free anterolateral thigh flaps (ALTF) can be employed. Previous studies have primarily focused on heel reconstruction when comparing different flaps, without considering the forefoot. This study aims to verify the clinical outcomes of these flaps and determine the appropriate donor site for weight-bearing areas of the foot including forefoot reconstruction. In a retrospective study, 39 patients who had undergone flap reconstruction of weight-bearing area defects in the foot with a follow-up period of ≥1 year were included. The patients were categorized into two groups: Group A (n = 19) using instep flaps, and Group B (n = 20) using non-instep flap including RSFs and ALTFs. Surgical outcomes were assessed based on the success of the flap, the presence of partial necrosis, the number of additional surgeries, and complications related to the donor site. Clinical evaluation included visual analogue scale (VAS) and American Orthopedic Foot and Ankle Society (AOFAS) score, and the occurrence of ulcers. All flaps were successful, while partial necrosis occurred in one case in Group B. There were three reclosures after flap border debridement in both groups and one donor site debridement in Group A. The VAS scores during weight-bearing were 2.0 ± 1.1 and 2.2 ± 1.5 for Groups A and B, respectively (p = .716). The AOFAS scores were 52.8 ± 6.8 and 50.2 ± 12.7 for Groups A and B, respectively (p = .435). The occurrence of ulcers was 0.4 ± 0.9 times for Group A and 0.3 ± 0.7 times for Group B, with no significant difference between the two groups (p = .453). There was no difference in clinical outcomes between the types of flaps after reconstruction of the forefoot and hindfoot. Therefore, it is recommended to choose the appropriate flap based on factors such as the size of the defect, its location, and vascular status rather than the type of flap.

Evaluating postoperative hernia incidence and risk factors following pelvic exenteration

Pelvic exenteration (PE) is a technically challenging surgical procedure. More recently, quality of life and survivorship following PEs are being increasingly acknowledged as important patient outcomes. This includes evaluating major long-term complications such as hernias, defined as the protrusion of internal organs through a facial defect (The PelvEx Collaborative in Br J Surg 109:1251–1263, 2022), for which there is currently limited literature. The aim of this paper is to ascertain the incidence and risk factors for postoperative hernia formation among our PE cohort managed at a quaternary centre.MethodA retrospective cohort study examining hernia formation following PE for locally advanced rectal carcinoma and locally recurrent rectal carcinoma between June 2010 and August 2022 at a quaternary cancer centre was performed. Baseline data evaluating patient characteristics, surgical techniques and outcomes was collated among a PE cohort of 243 patients. Postoperative hernia incidence was evaluated via independent radiological screening and clinical examination.ResultsA total of 79 patients (32.5%) were identified as having developed a hernia. Expectantly, those undergoing flap reconstruction had a lower incidence of postoperative hernias. Of the 79 patients who developed postoperative hernias, 16.5% reported symptoms with the most common symptom reported being pain. Reintervention was required in 18 patients (23%), all of which were operative.ConclusionThis study found over one-third of PE patients developed a hernia postoperatively. This paper highlights the importance of careful perioperative planning and optimization of patients to minimize morbidity.

Postsurgical Pyoderma Gangrenosum Requiring Plastic Surgical Intervention: A Practical Review.

Pyoderma gangrenosum is a neutrophilic dermatosis characterized by immune dysfunction and pathergy. Thus, it is frequently seen in patients with underlying systemic illnesses or postoperatively. For the performance of the debridement or closure of the resultant defect, plastic surgeons are often involved in the care of pyoderma patients. However, both procedures may exacerbate the injury. Therefore, plastic surgeons must be familiar with the presentation of postsurgical pyoderma to avoid further damage and safely repair related soft tissue defects. A systematic search of the PubMed/Medline database was performed using the following keywords: "pyoderma gangrenosum" and "surgery." This online database search has identified 656 studies published between 1958 and 2022. Only reconstructed cases of postsurgical pyoderma gangrenosum were selected. Twenty-eight patients who developed pyoderma after dermatologic, plastic, orthopedic, cardiovascular, general, or obstetric surgery were included in this study. The average time to the PG presentation and diagnosis was 5.5 and 17 days, respectively. Diagnostic scoring tools were not used, and the diagnosis was primarily based on histopathology after repeated treatment failures. The patients received split- or full-thickness skin grafts, local, pedicled, and free flaps. An estimated 82.1% underwent skin grafting, whereas 42.9% underwent flap reconstruction. In addition, 21.4% got both the graft and flap. Accurate diagnosis of PSPG, prevention of further surgical injury, and timely medical management are vital for improving patient outcomes. Reconstruction can be performed, if required. However, despite the availability of different reconstructive techniques, there is no standard approach to the management of the PSPG.

Outcomes of flap reconstruction for diabetic foot ulcers: a systematic review and meta-analysis of Clinical Studies

Background: People with diabetic foot ulcers (DFU) are at risk of major amputation, which is associated with a high mortality rate (exceeding 50% at five years) and reduced quality of life. We hypothesise that flap reconstruction of diabetic foot ulcers improves patient outcomes in comparison to standard treatment modalities including major amputation. Methods: MEDLINE, EMBASE, the Cochrane Library and grey literature were searched on 9 th February 2022. Comparative and single-arm studies reporting outcomes of DFU treated with local, regional or free flaps including function, limb loss, mortality, and flap failure were included. Risk of bias was assessed and meta-analysis of proportions was performed. Results: 3,878 records were retrieved, of which 45 met the inclusion criteria, including 1,681 patients who underwent flap reconstruction of DFU. Free flaps were most commonly performed (n = 1,257, 72%). Only one study utilised a verified functional outcome measure. At 12 months, the mortality rate was 6.35% (95% C.I. 3.89 – 10.20), limb loss rate was 11.39% (95% C.I. 7.02 – 17.96) and the free flap failure rate was 9.95% (95% C.I. 8.19 – 12.05). All studies were at high risk of bias. A comparative meta-analysis of interventions was not performed due to study method and outcome heterogeneity. Conclusions: There is short-term evidence that flap reconstruction (including microsurgical transfer) has low mortality, limb loss and flap failure rates. However, there are limited high-quality comparative studies, and uncertainty remains regarding the outcome of DFU flap reconstruction in comparison to other treatments.

Calculating Tumor Volume Using Three-Dimensional Models in Preoperative Soft-Tissue Sarcoma Surgical Planning: Does Size Matter?

This feasibility study aims to explore the use of three-dimensional virtual surgical planning to preoperatively determine the need for reconstructive surgery following resection of an extremity soft-tissue sarcoma. As flap reconstruction is performed more often in advanced disease, we hypothesized that tumor volume would be larger in the group of patients that had undergone flap reconstruction. All patients that were treated by surgical resection for an extremity soft-tissue sarcoma between 1 January 2016 and 1 October 2019 in the University Medical Center Groningen were included retrospectively. Three-dimensional models were created using the diagnostic magnetic resonance scan. Tumor volume was calculated for all patients. Three-dimensional tumor volume was 107.8 (349.1) mL in the group of patients that had undergone primary closure and 29.4 (47.4) mL in the group of patients in which a flap reconstruction was performed, p = 0.004. Three-dimensional tumor volume was 76.1 (295.3) mL in the group of patients with a complication following ESTS treatment, versus 57.0 (132.4) mL in patients with an uncomplicated course following ESTS treatment, p = 0.311. Patients who had undergone flap reconstruction had smaller tumor volumes compared to those in the group of patients treated by primary closure. Furthermore, a larger tumor volume did not result in complications for patients undergoing ESTS treatment. Therefore, tumor volume does not seem to influence the need for reconstruction. Despite the capability of three-dimensional virtual surgical planning to measure tumor volume, we do not recommend its utilization in the multidisciplinary extremity soft-tissue sarcoma treatment, considering the findings of the study.

A review of functional and surgical outcomes of gynaecological reconstruction in the context of pelvic exenteration

BackgroundRadical surgical excision may be the only curative option for patients with advanced pelvic malignancy, but concerns surrounding the functional outcomes and survivorship of patients undergoing exenterative surgery remain. This is especially important in the context of vulvovaginal resection, where patients are often younger and surgery can have a profoundly negative impact on quality of life, body image and overall wellbeing. Reconstructive procedures are an important means of mitigating these adverse effects but outcomes are poorly described. AimTo define the outcomes associated with gynaecological reconstructive procedures following pelvic exenterative surgery and to compare them with the outcomes of those patients who did not undergo reconstruction. MethodsAn international, multicentre retrospective investigation comparing the outcomes of reconstruction with no reconstruction. The protocol was prospectively registered (NCT05074069). Results334 patients were included. 77 patients had a neovagina reconstructed, 139 patients underwent flap reconstruction and 118 were not reconstructed. Patients who underwent reconstruction had a longer operative time and hospital stay with an increased risk of minor perineal complications. Reconstruction did not confer an increased risk of surgical reintervention, and overall complication rates were equivalent. Procedure-specific major morbidity was 5.2 % and 11.5 % for neovaginal and flap reconstruction, respectively. 66 % of patients undergoing neovaginal reconstruction experienced no long term morbidity. 7 % developed neovaginal stenosis and 12 % suffered disease recurrence. ConclusionNeovaginal reconstruction is safe in carefully selected patients and offers specific advantages over alternative techniques, with few patients requiring reoperation. Primary closure does not increase perineal morbidity.

Computed tomography-defined sarcopenia as a risk factor for short-term postoperative complications in oral cancer patients with free flap reconstruction: A retrospective population-based cohort study.

Postoperative complications after free flap reconstruction for oral cancer can increase cost and prolong hospitalization. This study explored risk factors for complications, focusing on sarcopenia. The study explored the associations between computed tomography-defined sarcopenia and the occurrence of postoperative complications, adjusted for age, gender, smoking, alcohol, ASA scoring, clinical stage of tumor, tumor site, type of free flap used, presence of tracheotomy, and blood test parameters. Of 253 patients, 17.39% (44/253) of oral cancer patients had comorbid sarcopenia. Univariate analysis showed an overall postoperative complication rate of 65.90% in the sarcopenia group and 51.67% in the non-sarcopenia group. Multivariate modeling showed sarcopenia and smoking were major risk factors for total and respiratory complications, increasing the risks by over two-fold. No factors significantly impacted surgery-specific complications. This study identified sarcopenia as a risk factor for postoperative complications in oral cancer patients undergoing flap reconstruction.

Frailty as a Predictor of Post-Surgical Outcomes in Patients With Cutaneous Malignancies of the Scalp and Neck Requiring Flap Reconstruction.

Investigate the ability of frailty status to predict post-surgical outcomes in patients with cutaneous malignancies of the scalp and neck undergoing flap reconstruction. National Surgical Quality Improvement Program database was used to isolate patients with cutaneous malignancies of the scalp and neck who underwent surgical resection between 2015 to 2019. Univariate and multivariate analyses were performed to determine if frailty score correlated with negative post-operative outcomes. Receiver operating characteristic (ROC) curves allowed testing of the discriminative performance of age versus frailty. This study demonstrated an independent correlation between frailty and major complications as well as non-home discharge. In ROC curve analysis, frailty demonstrated superior discrimination compared to age for predicting major complications. Our study demonstrated an association between increasing frailty and major complications as well as the likelihood of a non-home discharge. When compared to age, frailty was also shown to be a better predictor of major complications.

Flap Reconstruction Outcome Following Surgical Resection of Soft Tissue and Bone Sarcoma in the Setting of (Neo)adjuvant Therapy: A Sarcoma Center Experience.

Soft tissue and bone sarcomas are heterogeneous groups of malignant tumors. The shift in their management, with an emphasis on limb salvage, has deemed the involvement of reconstructive surgeons an integral part of their multidisciplinary treatment. We present our experience with free and pedicled flaps in the reconstruction of sarcomas at a tertiary referral university hospital and major sarcoma center. All patients undergoing flap reconstruction after sarcoma resection over a 5-year period have been included in the study. Patient-related data and postoperative complications were collected retrospectively, ensuring a minimum follow-up of 3 years. A total of 90 patients underwent treatment with 26 free flaps and 64 pedicled flaps. Postoperative complications occurred in 37.7% of patients, and the flap failure rate was 4.4%. Diabetes, alcohol consumption and male gender were associated with increased early necrosis of the flap. Preoperative chemotherapy significantly increased the occurrence of early infection and late dehiscence, while preoperative radiotherapy was associated with a higher incidence of lymphedema. Intraoperative radiotherapy was associated with late seromas and lymphedema. Reconstructive surgery with either pedicled or free flaps is reliable, but it can be demanding in the setting of sarcoma surgery. A higher complication rate is to be expected with neoadjuvant therapy and with certain comorbidities.

Surgical management of pressure ulcers in spinal cord injury patients.

Pressure ulcers (PU) are a common yet debilitating injury within the spinal cord injury (SCI) population. This retrospective data analysis is intended to identify the contributing factors, review the current management protocol, and risk of recurrence of PU in SCI patients at Victoria's state referral centre for traumatic spinal cord injuries. A retrospective audit of the medical records of SCI patients with pressure ulcers was conducted for the period of January 2016 to August 2021. Patients aged 18 years and older who presented for surgical management of their PU were included in the study. Among the 93 patients who met the inclusion criteria, there were a total of 195 surgeries for 129 PU. Ninety-seven percent were classified as grade of 3 or 4 and 53% had osteomyelitis on presentation. 58% were either current smokers or ex-smokers, and 19% were diabetic. Debridement alone was the most common type of surgical management (58%), followed by flap reconstruction (25%). Those who underwent flap reconstruction were admitted for 71 days longer, on average. 41% of the surgeries were associated with a post-operative complication, with the most prominent being an infection at 26%. Of the 129 PU, 11% recurred at least 4months post initial presentation. There are a multitude of a factors that impact prevalence, surgical complications, and recurrence of PU. This study provides insight into these factors to review our current practices and optimize surgical outcomes in the management of PU in the SCI population.

Use of negative pressure wound therapy on locoregional flaps: a case–control study

The use of negative pressure wound therapy (NPWT) is ubiquitous in the management of complex wounds. Extending beyond the traditional utility of NPWT, it has been used after reconstructive flap surgery in a few case series. The authors sought to investigate the outcomes of NPWT use on flap reconstruction in a case-control study. Patients who underwent flap reconstruction between November 2017 and January 2020 were reviewed for inclusion in the study, and divided into an NPWT group and a control group. For patients in the NPWT group, NPWT was used directly over the locoregional flap immediately post-surgery for 4-7 days, before switching to conventional dressings. The control group used conventional dressing materials immediately post-surgery. Outcome measures such as flap necrosis, surgical site infections (SSIs), wound dehiscence as well as time to full functional recovery and hospitalisation duration were evaluated. Of the 138 patients who underwent flap reconstruction, 37 who had free flap reconstructions were excluded, and 101 patients were included and divided into two groups: 51 patients in the NPWT group and 50 patients in the control group. Both groups had similar patient demographics, and patient and wound risk factors for impaired wound healing. Results showed that there was no statistically significant difference between flap necrosis, SSIs, wound dehiscence, hospitalisation duration as well as functional recovery rates. Cost analysis showed that the use of NPWT over flaps for the first seven postoperative days may potentially be more cost effective in our setting. In this study, the appropriate use of NPWT over flaps was safe and efficacious in the immediate postoperative setting, and was not inferior to the conventional dressings used for reconstructive flap surgery. The main benefits of NPWT over flaps include better exudate management, oedema reduction and potential cost savings. Further studies would be required to ascertain any further benefit.

A Patient with Acute Necrotizing Fasciitis after a Total Knee Replacement: A Case Report

Necrotizing fasciitis is a relatively rare and serious fatal soft-tissue infection that is characterized by a rapidly spreading bacterial infection located in the subcutaneous tissues. We report a 59-year-old man who was diagnosed with acute necrotizing fasciitis, following a primary total knee replacement. He received primary total knee replacement that was uneventful and smooth intraoperatively. An immediate high fever was reported in the next few days, with several complications, confirming a diagnosis of necrotizing fasciitis. The most effective treatment for this disease is a rapid primary diagnosis and surgical debridement. Gold standard treatment includes intravenous therapy, such as antibiotics, surgical debridement, and intensive care. As a result of possible GI complications that triggered necrotizing fasciitis, the patient underwent flap reconstruction. This report's aim is to review the comprehensive treatment, management, and experience of necrotizing fasciitis, highlighting the roles with a multidisciplinary care team for improving the condition of this patient.

A Size-Based Criteria for Flap Reconstruction After Thigh-Adductor, Soft-Tissue Sarcoma Resection.

Resection of soft-tissue sarcomas from the adductor compartment is associated with significant complications. Free/pedicled flaps often are used for wound closure, but their effect on healing is unclear. We compared wound complications, oncologic, and functional outcomes for patients undergoing flap reconstruction or primary closure following resection of adductor sarcomas. A total of 177 patients underwent resection of an adductor sarcoma with primary closure (PrC) or free/pedicled flap reconstruction (FR). Patient, tumor, and treatment characteristics were compared, as well as wound complications, oncologic, and functional outcomes (TESS/MSTS87/MSTS93). To examine the relative benefit of flap reconstruction, number needed to treat (NNT) was calculated. In total, 143 patients underwent PrC and 34 had FR, 68% of which were pedicled. There were few differences in demographic, tumor, or treatment characteristics. No significant difference was found in the rate of wound complications. Length of stay was significantly longer in FR (18 days vs. PrC 8 days; p < 0.01). Oncologic and functional outcomes were similar over 5 years follow-up. Uncomplicated wound healing occurred more often in FR compared with PrC for tumors with ≥15 cm (NNT = 8.4) or volumes ≥ 800 ml (NNT = 8.4). Tumors ≤ 336 ml do not benefit from a flap, whereas those > 600 ml are 1.5 times more likely to heal uneventfully after flap closure. Although flap use prolonged hospitalization, it decreased wound healing complications for larger tumors, and in all sized tumors, it demonstrated similar functional and oncologic outcomes to primary closure. Our size-based treatment criteria can help to identify patients with large adductor sarcomas who could benefit from flap reconstruction. (Retrospective cohort study).

The effect of botulinum neurotoxin A on soft-tissue complications in intraoral reconstructions

Intraoral reconstruction has become more common in recent years. Patients may suffer from complications because of hypersalivation. This issue can be overcome with an aid aimed at reducing saliva production. In this study, patients who underwent flap reconstruction were examined. The aim was to compare the complication rates between those who were administered with botulinum neurotoxin type A (BTXA) to the salivary glands before the reconstruction and those who were not. Patients who underwent flap reconstruction between January 2015 and January 2021 were included in the study. The patients were divided into 2 groups. BTXA was applied to the parotid and submandibular glands in the 1st group at least 8 days before the operation to reduce the salivary secretion. BTXA application was not applied to the patients in the 2nd group before the operation. A total of 35 patients were included in the study. There were 19 patients in group 1 and 16 patients in group 2. The tumor type in both groups was squamous cell carcinoma. For patients in the 1st group, salivary secretion decreased in an average of 3.84 days. In the statistical analysis, no significant difference was found between the groups in terms of age, comorbidity, smoking-complication development, and comorbidity-complication development. When infection was excluded, there was a significant difference in the development of complications between the groups. BTXA application before the operation is beneficial to minimize complications in patients who plan to undergo elective intraoral reconstruction.

Dufourmentel Rhomboid Flap versus the Karydakis and Bascom Flap Reconstruction Following Wide Excision of Pilonidal Sinus Disease

Abstract Background: Primary closure of the defect following radical excision of pilonidal sinus disease often has high complication rates. Objectives: This study aims to compare the outcomes of the Karydakis and Bascom off-midline flap closure techniques with the more recently described Dufourmentel rhomboid flap technique. Design: Retrospective cohort study. Setting: Patients who underwent elective pilonidal sinus excision with flap reconstruction at a tertiary referral center from January 2019 to January 2023. Patients and Methods: De-identified data of patients who underwent elective pilonidal sinus excision with flap reconstruction at a tertiary referral center from January 2019 to January 2023 were analyzed. Patients who underwent pilonidal sinus surgery without flap reconstruction were not included in the analysis. Institutional ethical committee review was waived for this study. Main Outcome Measures: Wound healing time, postoperative complications, disease recurrence, operative duration, and length of hospital stay. Sample Size: Forty-four patients. Results: Over a 4-year duration, 44 patients had elective pilonidal sinus surgery, of whom 44 (36 men, eight women) underwent flap reconstruction of the defect. Mean age and body mass index was 25.6 years and 26.6 kg/m2, respectively. The overall mean complete wound healing time was 10.8 weeks, with the Dufourmentel group having the quickest healing time compared to the Karydakis and Bascom groups (6.1 weeks versus 10.8 weeks versus 13.9 weeks, respectively; P = 0.206) At a mean follow-up duration of 8 months, 18 (40.1%) patients developed postoperative wound complications. Overall wound complication rate was lowest in the Dufourmentel group (9.1% versus 52.9% versus 56.3%, respectively; P = 0.030). This was largely contributed by the reduced wound dehiscence rate (9.1% versus 35.3% versus 56.3%, respectively; P = 0.043). The rates of wound infection, sinus recurrence, and reoperation were low and statistically comparable across all three groups. Conclusion: Our findings suggest the superiority of the Dufourmentel flap reconstruction technique compared to the Karydakis and Bascom closure techniques following elective pilonidal sinus excision. Limitations: Retrospective study with a small sample size and short follow-up duration. Conflict of Interest: The authors have no conflict of interest to declare.

Reintroducing Flap Reconstruction: One Institution's Safe Return to Flap Surgery during the COVID-19 Pandemic.

Prevention of nosocomial coronavirus disease 2019 (COVID-19) infection for patients undergoing flap-based reconstructive surgery is crucial to providing care and maintaining operative volume and income to support plastic surgery programs. We conducted this study to (1) determine the postoperative incidence of COVID-19 among patients undergoing flap reconstruction from December 1, 2019 to November 1, 2020 and (2) compare 30-day outcomes between patients who underwent surgery before and during the early pandemic. We conducted an 11-month retrospective cohort study of all patients who underwent flap reconstruction across our institution. We abstracted patient demographics, intraoperative management, COVID-19 testing history, and 30-day postoperative complications from electronic health records. Nosocomial COVID-19 infection was defined as reverse transcription polymerase chain reaction (RT-PCR) viral ribonucleic acid detection within 30 days of patients' postoperative course or during initial surgical admission. We used chi-squared tests to compare postoperative outcomes between patients who underwent surgery before (prior to March 12, 2021, when our institution admitted its first COVID-19 patient) versus during (on/after March 12, 2021) the pandemic. Among the 220 patients (mean [standard deviation] age = 53.8 [18.1] years; female = 54.8%) who underwent flap reconstruction, none had nosocomial COVID-19 infection. Five (2%) patients eventually tested COVID-19 positive (median time from surgery to diagnosis: 9 months, range: 1.5-11 months) with one developing partial flap loss while infected. Between patients who underwent free flap surgery before and during the pandemic, there were no significant differences in 30-day takebacks (15.6% vs. 16.6%, respectively; p > 0.999), readmissions (9.4% vs. 12.6%, respectively; p = 0.53), and surgical complications (e.g., total flap loss 1.6% vs. 2.1%, p = 0.81). Robust precautions can ensure the safety of patients undergoing flap surgeries across an academic medical institution, even during periods of high COVID-19 admission rates. Further studies are needed to generate evidence-based guidelines that optimize infection control and flap survival for patients undergoing reconstruction.

Submental Flap as a Reconstructive Option for Reconstruction in Oral Cancer

Objective: To demonstrate the advantages and oncological safety of the submental flap.&#x0D; Study Design: Case series.&#x0D; Place and Duration of Study: Department of Plastic and Reconstructive Study, Combined Military Hospital Rawalpindi, Multan and Peshawar Pakistan, from Jul 2014 to May 2020.&#x0D; Methodology: Twenty patients underwent flap reconstruction with a submental flap. The patients were diagnosed with squamous cell carcinoma, basal cell carcinoma and verrucous carcinoma at different sites of the head and neck. Only patients with no cervical lymph node metastasis were included.&#x0D; Results: We operated a total of 20 patients, out of which 11 (55%) were male and 9 (45%) were female. The mean age was 62.75 years (range: 47-80 years). Thirteen (65%) patients were diagnosed with Squamous cell carcinoma, 5 (25%) with Basal cell carcinoma and 2 (10%) were diagnosed with Verrucous carcinoma on histopathology. Two (10%) patients reported back with regional recurrence and were given postoperative radiotherapy. One (5%) patient had complete flap loss while 2 (10%) had distal tip necrosis.&#x0D; Conclusion: In carefully selected cases submental flap is a viable option, without the risk of occult metastasis.

Characteristics and Outcomes of Patients Undergoing Surgical Management of Hidradenitis Suppurativa: An ACS-NSQIP Data Analysis.

Objective: Hidradenitis suppurativa (HS) is a painful inflammatory skin disease. Management is largely medical, with surgery reserved for severe refractory cases. In this study, we sought to conduct a retrospective analysis of a multi-institutional surgical database to investigate the surgical management of patients with HS and identify trends in the postoperative outcomes. Approach: The 2011-2019 American College of Surgeons National Surgical Quality Improvement Program (NSQIP) database was reviewed to identify patients who underwent surgery for management of HS. Postoperative outcomes were assessed, including surgical and medical complications, length of hospital stay, reoperation, readmission, and nonhome discharge. This article was reported according to the STROBE criteria. Results: We identified 1,030 patients, of which 62% were female and 50% were black. The most common comorbidity was obesity (61%). Surgery was mainly performed by general surgeons (62%) and plastic surgeons (31%). Complications were overall low, with readmission being the most common (7.1%, unplanned 6.0%), followed by reoperation (5.8%). The most common surgical complication was superficial incisional infection (5.1%) and most common medical complication was sepsis (3.8%). Obesity is seen to affect surgical complication rates, with patients with obesity having higher rates of dehiscence (obese: 3.1% and nonobese: 1.0%; p = 0.03) but lower rates of organ space infection (obese: 0.5% and nonobese: 2.0%; p = 0.03) and transfusion (obese: 2.5% and nonobese: 5.2%; p = 0.04). A focus on complications in patients undergoing flap reconstruction (n = 293; 23%), identified higher rates of surgical complications, with superficial incisional infection being the most common (flap reconstruction: 7.5% and incision and drainage, debridement, skin graft: 4.1%; p = 0.04). Innovation: The surgical management of HS is analyzed at the national level, with postoperative complications seen to depend on race and obesity-status. Conclusions: Surgical management for HS is associated with low postoperative complications, making surgery a viable treatment option for this debilitating disease.
