Background: Chronic empyema is usually considered to be very challenging in clinical management and has a high mortality rate. On this basis, if combined with bronchopleural fistula (BPF) and huge irregular abscess cavity, there are not many treatment options available, and some patients may even develop cachexia due to long-term chronic consumption. The application of pedicled combined muscle flaps to repair and reconstruct according to the region of abscess cavity may improve the quality of life for such complex cases. Case presentation: A 59-year-old male patient underwent surgical treatment for lung squamous cell carcinoma 2 years ago. Due to the low differentiation of malignant tumor, empyema complicated with BPF occurred after the fourth cycle of chemotherapy. His past medical history was free of other illnesses. The patient was admitted to our hospital for further treatment because of long-term chest tube drainage and obvious respiratory irritation symptoms such as cough during body position change. Chest computed tomography (CT) scan revealed a left-sided hydropneumothorax. Bronchoscopy revealed BPF. Considering that the volume of the abscess cavity did not shrink significantly after long-term drainage, we chose first-stage surgery to complete the debridement of empyema and the closure of the fistula. In the second-stage surgery, the combined pedicled muscle flaps were used to complete the filling in different areas of the huge irregular residual cavity. This surgical mode of staging and sub-regional treatment of abscess cavity has achieved satisfactory clinical results. Conclusions: Utilizing the pedicled combined muscle flaps to address chronic empyema accompanied by a huge irregular abscess cavity shows promise as a treatment method for eliminating residual cavity in various regions.

Complications in the femoral area following vascular surgery are frequent and linked to considerable morbidity, including the risk of underlying graft infection. Sartorius muscle flaps are an important adjunct for the treatment of wound complications. In this study, we examined our experience with prophylactic sartorius muscle flap coverage and its association with prosthetic vascular graft infection. In this single-center analysis, electronic medical records were retrospectively reviewed for all sartorius muscle flap procedures performed from 2012 to 2021. Prophylactic indication was defined as flap reconstruction during index revascularization in the absence of active inguinal infection. Over the 9-y period, a total of 54 prophylactic sartorius flaps were performed in 47 patients. The median patient age was 66 y (interquartile range [IQR] 61-77 y). Wound complications requiring reintervention occurred in 16 (29.6%) patients, including 6 (11.1%) surgical site infections, 5 (9.3%) wound dehiscence, and 5 (9.3%) infected seromata. Among patients suffering wound complications, 30-d readmission (75.0% versus 26.3%, P = 0.004) and reoperative flap creation rates (25.0% versus 2.6%, P = 0.010) were higher, whereas 30-d mortality rates (0.0% versus 5.3%, P = 0.51) were similar. Only one patient (1.9%) developed vascular graft infection over a median follow-up period of 2.4 y (IQR 0.9-4.0 y). On multivariate analysis, body mass index (adjusted odds ratio 1.23, 95% confidence interval, 1.12-1.35, P = 0.023) was associated with reoperative wound complications. Wound complications were common after prophylactic sartorius flap creation in this high-risk population; however, infection of the underlying vascular graft was rare. These data suggest that sartorius flap may be effective in a prophylactic role. [ABSTRACT FROM AUTHOR]

INTRODUCTION. One of the most formidable complications in thoracic surgery is bronchopleural fistula after pneumonectomy. Main bronchus stump reinforcement during surgery is used as method of prevention of this complication. The question of the preferred plastic material remains debatable.The OBJECTIVE was to compare the results of myoplasty and diaphragmoplasty of the right main bronchus stump after pneumonectomy performed for destructive pulmonary tuberculosis.METHODS AND MATERIALS. A retrospective study from 2015 to 2022 was conducted. The study included 30 patients who were divided into 2 groups. Group 1 included 19 patients who underwent diaphragmoplasty; group 2 included 11 patients who underwent myoplasty. Patients were comparable in terms of sex, age, functional indices, and features of the course and prevalence of the underlying disease. The short-term and long-term results of surgical treatment were compared.RESULTS. Complicated course of the postoperative period was observed in 6 (31.6 %) patients in group 1 and in 5 (45.5 %) patients in group 2. Satisfactory immediate result in group 1 was achieved in 17 (89.5 %) patients, in group 2 – in 8 (72.7 %). In the remote period, the result of complex treatment of TB patients in group 1: successful treatment – 13 (68.5 %), ineffective treatment – 2 (10.5 %), loss to follow-up – 2 (10.5 %), lethal outcome – in 2 (10.5 %); in group 2: successful treatment – 8 (72.7 %), ineffective treatment – in 3 (27.3 %).CONCLUSIONS. Right-sided pneumonectomy in patients with destructive pulmonary tuberculosis with drug-resistant mycobacteria is accompanied by a high risk of main bronchus stump failure. The diaphragm and chest wall muscles are reliable materials for strengthening the main bronchus stump.

Abstract This study aimed to investigate the clinical outcomes of local muscle or myocutaneous flap transfer for emergent repair of Gustilo IIIB open tibiofibular fractures. This retrospective case series study included patients with Gustilo IIIB open tibiofibular fractures treated by local muscle or myocutaneous flap transfer in Weifang People’s Hospital between May 2016 and April 2021. Fifteenpatients (11 males aged 19–72 years) were included. The follow-up ranged from 8 to 24 months. The ranges of bone healing time and wound healing time were 6–17 months and 1–3 weeks, respectively. The length of hospital stay was 26 days (11–50 days). All patients reported acceptable functional recovery and satisfactory leg appearance, with Johner-Wruhs scores of excellent, good, and fair in 10, four, and one patients, respectively. The excellent-good rate was 93.3%. The complications included one case of infection and one case of nonunion. In conclusion, local muscle or myocutaneous flap transfer for emergent repair of Gustilo IIIB open tibiofibular fractures may be useful in providing adequate soft tissue coverage and fracture healing with low complication and infection rates.

Summary: Soft tissue defects of the distal third of the leg are challenging and management with simple split thickness skin graft or conservative measures is often difficult. The peroneus brevis muscle flap is well described in the literature to cover such defects. The aim of our study was to review the different applications and potential complications of the peroneus brevis muscle flap.A comprehensive review of all existing evidence on the use of peroneus brevis muscle flaps for coverage of defects in the distal third of the leg in adult populations was performed.Two hundred forty-eight records were identified in the literature search, among which 15 met the PICOS (Patient, Intervention, Comparison, Outcome and Study design) criteria. All selected studies were retrospective. Overall, 222 patients who received peroneus brevis muscle flaps were analyzed. Indications for reconstruction were post-traumatic defects, infected wounds, and chronic wounds. The overall complication rate was 21% (46/222) with the most commonly reported complication being skin graft loss. We observed 2 cases of partial flap loss, 17 cases of skin graft loss, 2 cases of post-operative hematoma, 2 cases of recurrent infection, 12 cases of partial flap necrosis, 3 cases of skin graft necrosis, and 8 cases of delayed wound healing. Overall, 16 patients (7%) required revision surgery. No cases of donor site morbidity were described.The current review shows that the peroneus brevis muscle flap is a versatile and reliable option for the coverage of small to medium sized defects of the distal leg, ankle, and foot with low complication rates and donor site morbidity.

Background: Incisional complications of groin after inflow or infrainguinal bypasses with prosthetic conduits can result in major morbidities that require reoperation, infected graft removal, and limb loss. Muscle flaps are typically performed to treat groin wound complications, but they are also done prophylactically at the time of index procedures in certain high‐risk‐for‐poor‐healing patients to mitigate anticipated groin wound complications. We used a nationwide multi‐institutional database to investigate outcomes of prophylactic muscle flaps in high‐risk patients who underwent prosthetic bypasses involving femoral anastomosis. Methods: We utilized ACS‐NSQIP database 2005–2021 to identify all elective inflow and infrainguinal bypasses that involve femoral anastomoses. Only high‐risk patients for poor incisional healing who underwent prosthetic conduit bypasses were selected. A 1:3 propensity‐matching was performed to obtain two comparable studied groups between those with (FLAP) and without prophylactic muscle flaps (NOFLAP) based on demographics and comorbidities. 30‐day postoperative outcomes were compared. Results: Among 35,011 NOFLAP, 990 of them were propensity‐matched to 330 FLAP. There was no significant difference in 30‐day mortality, MACE, pulmonary, or renal complications. FLAP was associated with higher bleeding requiring transfusion, longer operative time, and longer hospital stay. FLAP also had higher overall wound complications (15.2% vs. 10.6%; p = 0.03), especially deep incisional infection (4.9% vs. 2.4%; p = 0.04). Conclusion: Prophylactic muscle flap for prosthetic bypasses involving femoral anastomosis in high‐risk‐for‐poor‐healing patients does not appear to mitigate 30‐day wound complications. Caution should be exercised with this practice and more long‐term data should be obtained to determine whether prophylactic flaps decrease the incidence of graft infection. [ABSTRACT FROM AUTHOR]

Racial disparities persist in surgical outcomes after spine surgery for primary and metastatic cancers. Muscle flap closure of spinal defects after oncologic resection has been shown to reduce wound complication rate with favorable cost-effectiveness. It is currently unknown whether racial disparities may affect the reception of this treatment. Spinal surgery procedures for tumor resection and subsequent reconstruction were identified in the 2011–2022 National Surgical Quality Improvement Program databases. Cases were propensity score matched for covariates like age, comorbidities, number of vertebral levels reconstructed, and length of stay to isolate the predictive impact of race on reception of muscle flap closure (p < 0.05). A total of 9467 patients who underwent oncologic spine surgery and had known race and ethnicity were identified in the final cohort. Two hundred thirty-two (2.5%) cases included muscle flap closure during the index surgery. After matching (n = 4196), minority race/ethnicity was associated with lower rates of muscle flap closure (2.2%) than non-Hispanic White race/ethnicity (3.8%) (p = 0.0037). Upon weighted univariate logistic regression, minority racial and ethnic identification also predicted lower likelihood of muscle flap closure (OR: 0.57, 95% CI: 0.52–0.63, p < 0.001). Among patients who received muscle flap closure, the overall rate of all major or minor thirty-day postoperative complications was not different depending on race and ethnicity (p > 0.05). There are evident racial disparities in the reception of muscle flap closure after oncologic spine surgery. Further work may investigate the role of intersecting socioeconomic factors like insurance status and hospital characteristics. Muscle flap closure is a surgical technique within plastic surgery that has been associated with lower rates of complications after spine surgery to remove tumors. Our study shows that minority racial and ethnic groups are less likely on average to receive muscle flap closure. [ABSTRACT FROM AUTHOR]

Purpose: Facial paralysis results from congenital or acquired facial nerve damage, leading to significant cosmetic and functional deficits. Surgical resection of parotid and midface tumors can cause facial paralysis, necessitating effective treatment strategies. This review addresses the challenge of restoring movement and function in late-stage facial paralysis, focusing on dynamic repair techniques involving nerve and muscle transplantation. Methods: The review encompasses studies on dynamic repair surgery for late facial paralysis, including techniques such as local muscle flap with pedicle transfer, vascularized nerve flap with pedicle transfer, and multiple muscle flap procedures. A systematic literature search was conducted using PubMed, Web of Science, and Google Scholar, covering studies from 2000 to 2024. Keywords included "dynamic repair", "late-stage facial paralysis", "nerve and muscle transplantation", "muscle flap", and "tendon transposition". Included were clinical studies, systematic reviews, and meta-analyses reporting surgical outcomes. Exclusion criteria included studies with insufficient data and non-peer-reviewed articles. Results: Dynamic repair techniques involving nerve and muscle transplantation are essential for treating late-stage facial paralysis. Each surgical method has strengths and limitations. The masseter muscle flap demonstrates high success rates, although it can cause horizontal tension and jaw contour issues. The temporalis muscle flap is effective for smile restoration but may lead to temporal concavity. The gracilis muscle flap is widely used, especially with dual nerve innervation, showing high success in spontaneous smiles but requiring a longer recovery period. The latissimus dorsi flap is effective but can cause edema and shoulder issues. The serratus anterior free flap offers flexibility with precise vector positioning but may not achieve adequate lip elevation and can cause cheek swelling. Combined multi-flap surgeries provide more natural facial expressions but increase surgical complexity and require advanced microsurgical skills. Conclusions: Dual nerve innervation shows promise for restoring spontaneous smiles. One-stage surgery offers faster recovery and reduced financial burden. Comprehensive patient evaluation is crucial to select the most suitable surgical method. Dynamic repair techniques involving nerve and muscle transplantation provide effective solutions for restoring function and aesthetics in late-stage facial paralysis. Future research should focus on long-term outcomes, patient satisfaction, and standardizing surgical protocols to optimize treatment strategies. [ABSTRACT FROM AUTHOR]

Managing wounds of the lateral malleolus is challenging owing to limited nearby tissues and possibly injured or inadequate vessels for free flaps, especially in case of underlying infections. Moreover, free flaps require specialized skills and are not suitable for every patient. Therefore, identifying reliable local alternatives is crucial. This retrospective study investigated the efficacy and safety of the distally based peroneus brevis muscle flap in treating complex and infected soft-tissue defects of the lateral malleolus. A retrospective medical chart review of all patients who underwent a distally based peroneus brevis muscle flap reconstruction in the context of an infected lateral malleolus defect at Geneva University Hospitals between October 2020 and January 2024 was performed. Ten patients underwent lateral malleolus reconstruction using a distally based peroneus brevis muscle flap primarily to address post-traumatic infections. Flap coverage was performed within 4 weeks of infection onset for post-traumatic cases, alongside antibiotic treatment. The defects were moderate in size, with a median width of 2.5 cm and length of 5.5 cm. There were no complete or partial flap failures. All patients regained the ability to walk within 5 days after surgery. The distally based peroneus brevis muscle flap was efficient in managing complex and infected soft-tissue defects of the lateral malleolus, with control of infection in all patients and minimal donor-site morbidity.

Case summary: A cat aged 12 years and 7 months was referred to a multidisciplinary hospital for investigation of feline injection site sarcoma (FISS) on the left thoracolumbar region. A CT examination of the mass revealed a multi-lobulated mass affecting the body wall, extending from the level of lumbar vertebrae L2 to L4. The mass was excised with 5 cm lateral margins, including resection of the 13th left rib, the caudal edge of the latissimus dorsi (LD) muscle, full-thickness abdominal wall and sections of the lumbar epaxial muscles. To reconstruct the defect, a combination of muscle flaps was used. This included diaphragmatic advancement and lateralisation, rotation of the LD, and creation of transposition flaps from the internal abdominal oblique and external abdominal oblique muscles, ensuring closure without tension. Skin closure required mobilising an inguinal flank fold flap. The cat was discharged from hospital 3 days postoperatively. Histopathology confirmed a diagnosis of FISS with clean wide margins. A gradual return to normal activity and complete healing of the surgical site was reported on follow-up, with one minor complication related to the skin flap (bruising at the base of the inguinal flank fold flap). Relevance and novel information: This report describes the use of the aforementioned combination of muscle flaps to close a major abdominal wall defect in a cat with an excellent outcome. Practitioners can consider this technique when planning tissue reconstruction after FISS resection. [ABSTRACT FROM AUTHOR]

To study the surgical result and efficacy of different methods of mastoid obliteration with cavity care. This prospective study included 60 patients who had cholesteatoma, conducted in the Department of Ear Nose and Throat (ENT), Institute of Medical Sciences, Banaras Hindu University, Varanasi from July 2015 to July 2017. The mastoid cavity was obliterated with either muscle flap/bone dust/hydroxyapatite. detailed history otoscopic examination was done pre-operatively and follow up were recorded at 1 month and 3 months in postoperative period. 60 patients were included, who underwent canal wall down mastoid surgery. each group muscle flap (group 1), bone dust (group 2) and hydroxyapatite (group 3) included 20 patients, age group 31–40 year with its maximum incidence of 43.3%, Preop PTA value were almost equal in all group but on comparison at 1 month in postoperative period significant improvement was present in group 1 versus 2(0.021) and group 2 versus 3(0.003) but not in group 1 versus 3. Although at 3 month there were significant improvement was present in all groups. The incidence of pain, discharge, giddiness and wax formation were markedly reduced and healing of cavities was early and better in obliterated cavities done by muscle flap and bone dust material as compared to hydroxyapatite cavities, at the end of 3 months. outcome and quality of life was better and almost equal in muscle flap and bone dust material group as compared to hydroxyapatite group.

Poststernotomy mediastinitis is the most severe and dangerous complication in cardiac surgery. Treatment of such patients still poses great difficulties for the surgeon dealing with this problem. At the reconstructive stage, they consist in the lack of criteria for choosing a method of plastic surgery and standardized surgical technologies. The use of autologous tissues is generally performed: greater omentum and muscle flaps. The article presents the experience of treating a patient with poststernotomy mediastinitis. The surgery was two-staged. The effectiveness of using vacuum-assisted dressings has been demonstrated. Performing final debridement and wound preparation followed by repair of the defect with a full-thickness flap of the pectoralis major muscle on the perforating branch of the internal thoracic artery led to the patient’s recovery.

Purulent arthritis of the sternoclavicular joint requires surgical treatment. The volume of the intervention depends on the degree of the joint's transformation and patient's general condition. The resulting defect of the chest wall tissues requires surgical closure at the reconstructive stage. In case of an extensive defect area with a skin deficiency, it is most advisable to use full-thickness flaps of the latissimus dorsi or pectoralis major muscles. The article presents a clinical case of a patient operated for purulent arthritis of the sternoclavicular joint. The surgical treatment was planned in two stages. During the first stage, the use of vacuum-assisted dressings demonstrated its effectiveness. The second, reconstructive stage, included plastic surgery for the chest wall defect using a full-thickness flap of the pectoralis major on the thoracic branch of the thoracoacromial artery. The progress of the patient's surgical and general treatment was described in detail.

To explore the method and significance of pelvic floor peritoneal reconstruction after abdomino-perineal resection for low rectal cancer. By searching the literature on pelvic floor structure reconstruction and pelvic floor peritoneum reconstruction after rectal cancer surgery, and reviewing the pelvic floor reconstruction technology of rectal cancer, it is found that it is necessary to close the pelvic floor peritoneum after laparoscopic abdomino-perineal resection of rectal cancer. Although it increases the difficulty of surgery for surgeons, it can reduce the incidence of pelvic and perineal infection, intestinal adhesion, intestinal obstruction and radiation enteritis, and improve the quality of life of patients. This article reviews the methods of pelvic floor reconstruction and pelvic floor peritoneal reconstruction and their advantages and disadvantages. [ABSTRACT FROM AUTHOR]

A judicious, well-planned bone and soft tissue debridement remains one of the cornerstones of state-of-the-art treatment of fracture-related infection (FRI). Meticulous surgical excision of all non-viable tissue can, however, lead to the creation of large soft tissue defects. The management of these defects is complex and numerous factors need to be considered when selecting the most appropriate approach. This narrative review summarizes the current evidence with respect to soft tissue management in patients diagnosed with FRI. Specifically we discuss the optimal timing for tissue closure following debridement in cases of FRI, the need for negative microbiological culture results from the surgical site as a prerequisite for definitive wound closure, the optimal type of flap in case of large soft tissue defects caused by FRI and the role of negative pressure wound therapy (NPWT) in FRI. Finally, recommendations are made with regard to soft tissue management in FRI that should be useful for clinicians in daily clinical practice. Level of evidence Level V. [ABSTRACT FROM AUTHOR]

Cloacal exstrophy (CE) is rare and challenging to reconstruct. In the majority of CE patients voided continence cannot be achieved and so patients often undergo bladder neck closure (BNC). Prior mucosal violations (MVs), a surgical event when the bladder mucosa was opened or closed, significantly predicted failed BNC in classic bladder exstrophy with an increased likelihood of failure after 3 or more MVs. The aim of this study was to assess predictors for failed BNC in CE. CE patients who underwent BNC were reviewed for risk factors for failure including osteotomy use, successful primary closure, and number of MVs. Chi-squared and Fisher's exact tests were used for comparing baseline characteristics and surgical details. Thirty-five patients underwent BNC. Eleven patients (31.4%) failed BNC including a vesicoperineal fistula in nine, vesicourethral and vesicocutaneous fistula in one each. The fistula rate in patients with 2 or more MVs was 47.4% (p = 0.0252). Two patients subsequently developed a vesicocutaneous fistula after undergoing repeated cystolithotomies. A rectus abdominis or gracilis muscle flap were used to close the fistula in 11 and 2 patients, respectively. MVs have a greater impact in CE with an increased risk of failed BNC after 2 MVs. CE patients are most likely to develop a vesicoperineal fistula while a vesicocutaneous fistula is more likely after repeat cystolithotomy. A prophylactic muscle flap should be considered at time of BNC in patients with 2 or more MVs. Prognosis Study, Level III. [Display omitted] [ABSTRACT FROM AUTHOR]

Diabetic patients often experience lower extremity wounds resulting from foot deformity, poor circulation and neuropathy. Conditions such as gangrene or osteomyelitis often require surgical intervention resulting in large tissue defects. Use of a muscle flap may be considered to fill in the wound defect, cover exposed bones, and bring in well vascularized tissue to the area. Synthetic electrospun fiber matrix (SEFM) offers a unique construct to augment these flap procedures and allows for quicker wound healing. In the present two-patient case report, patients underwent SEFM-augmented abductor digiti minimi muscle flaps to encourage healing of large surgical defects on the lateral foot. Both patients presented with gangrenous and infected wounds requiring surgical resection and debridement of fifth metatarsal to address underlying osteomyelitis and necrotic bone. Subsequently, proximally or distally based abductor digiti minimi muscle flap was performed and the SEFM was then applied over the muscle flap. Both wounds achieved closure at around 14 weeks without complication. Use of the SEFM in conjunction with perforator-based muscle flaps represents a novel approach in treating poorly vascularized surgical wounds in a challenging patient population.

Free flap reconstruction is the standard of care for extensive defects of the head and neck area. In this study, two types of free flaps, the antero-lateral thigh flap (ALT) and the vastus lateralis muscle flap, were compared. The primary endpoint was flap success, secondary endpoints were complication rates, hospitalization and surgery time. Cases with defect situations of the scalp and consecutive microvascular free flap reconstructions using either ALT flaps or vastus lateralis muscle flaps between 2014 and 2022 were retrospectively analyzed. Indications, perioperative handling and outcomes were compared. Twenty patients were included in the analysis. Ten patients (50%) received a free flap reconstruction using an ALT flap and ten patients (50%) received a vastus lateralis flap. A simultaneous two-team approach was possible in each case and the flap success rate was 100% with the need for one successful anastomosis revision. The mean defect size in our cohort was 147 ± 46 cm2. There were no significant differences in surgery time, duration of hospitalization or complication rate between both cohorts. Both free flaps, the ALT and the vastus lateralis flap, are suitable for the closure of large scalp defects. They provide high success rates, short surgery times without the need for patient repositioning and low donor-site morbidity. The vastus lateralis muscle flap bares the advantage of being perforator-independent and allows for the preparation of long vessels for anastomosis if needed while baring the disadvantage of a prolonged period of healing via granulation or the need for secondary surgery in terms of covering by split-thickness skin grafts which may interfere with necessary adjuvant treatment in oncological patients.

Abstract Background Rectovaginal fistula (RVF) is a troublesome and refractory complication after low anterior resection (LAR) for rectal cancer. An omental flap repair was performed for the RVF caused due to Crohn’s disease and childbirth trauma. However, there are few cases of an omental flap repair for RVF after LAR. Herein, we present a successfully repaired case of RVF by omental flap coverage after LAR for rectal cancer. Case presentation A 50-year-old female patient with advanced rectal cancer underwent laparoscopic LAR with double-stapling technique anastomosis and achieved curative resection. She complained of a stool from the vagina and was diagnosed with RVF on the postoperative day (POD) 18. Conservative therapy was ineffective. We performed laparoscopic fistula resection and direct closure of the vagina and rectum, designed the omentum that could reach the pelvis, repaired RVF by omental flap coverage, and performed transverse colostomy on POD 25. She was discharged on initial POD 48. Seven months after the initial operation, colostomy closure was administered. There was no recurrence of RVF found 1 year after the initial operation. Conclusions The patient achieved an omental flap coverage for RVF. We successfully performed the omental flap coverage repair in patients with RVF after the leakage of LAR. An omental flap may become an alternative treatment for muscle flap or an effective treatment for RVF.

The medial gastrocnemius (GN) muscle flap is a historical reconstructive option in lower limb reconstruction. The flap is proximally based on the medial sural artery, and it is assumed not possible to harvest a distally based flap because of the absence of other minor pedicles. The aim of this study is to investigate the presence and the anatomy of a distal secondary pedicle given off by the posterior tibial artery (PTA). A retrospective CTA study was performed of 120 limbs between April 2018 and June 2020. 3D reconstruction was performed to delineate the anatomy of the distal secondary pedicle, if present. The distance of the pedicle, if found, from the intermalleolar line to the patella was noted. The number of pedicles, if multiple, was documented, as well as branches to the soleus muscle and the skin. A distal pedicle to the gastrocnemius muscle was found in 64% of limbs. The average location from the intermalleolar line is 168 mm. The branching pattern from the PTA showed an isolated vessel going to the distal medial gastrocnemius (32.8%), two branches to the medial gastrocnemius and skin (39.3%), two branches to the medial gastrocnemius and soleus (24.6%), and three branches to the medial gastrocnemius, soleus, and the skin (3.3%). This study confirms the presence of the secondary axial distal pedicle of the GN muscle. Furthermore, this study confirms that there is a likely association between the distal medial gastrocnemius pedicle and the PTA skin perforators. [ABSTRACT FROM AUTHOR]

Background. Resection arthroplasty with non-free muscle flap transfer allows to quickly eliminate the infection, but resulting in functional impairment of hip joint. To date, there are only a few publications with a small number of observations, where the proportion of patients who underwent the second stage of the revision hip arthroplasty (rTHA) is extremely small. The aim of the study was to evaluate the effect of resection arthroplasty on the functional outcomes and incidence of adverse outcomes in patients with difficult-to-treat (DTT) periprosthetic infection who had previously undergone resection arthroplasty with a non-free transfer of the axial flap fom the vastus lateralis muscle. Methods. The prospective study included 24 patients. During the period 20112021, at the first stage of the treatment for chronic recurrent DTT PJI of the hip, resection arthroplasty was performed with a non-free transfer of an island flap from the vastus lateralis muscle. Subsequent reimplantation of the endoprosthesis was performed in at least 1 year after the infection remission. The functional outcomes, degree of the lower limb shortening immediately before and in two or more years after revision arthroplasty (rTHA), the results of the microbiological cultures at the first and second stages of PJI treatment, technical aspects of the surgery as well as the postoperative period and long-term PJI remission were studied. Results. Revision arthroplasty resulted in a statistically significant improvement of the postoperative functional outcome and quality of life in patients. The average Harris score agter rTHA increased from 53 to 83 points after surgery, EQ-5D degree of the quality of life increased from 50 points to 80, the overall score from 0.61 to 0.74 and average intensity of pain via VAS decreased from 3 points to 1 point in 3.1 years after rTHA (p0.05). After reEP, complete restoration of the limb length was achieved in 29.1% of cases (n = 7) with an average compensation of the limb length for 4.5 cm. In 66.7% of patients (n = 16), the results of the intraoperative tissue biopsy microbiological analysis during reEP were culture negative. The recurrence rate of PJI was 12.5% (n = 3) up to 30 days after rTHA and 4.2% (n = 1) with a follow-up period of 3.1 years (IQR 2.14.1). With a single revision surgery performed without a delay, stable remission of DTT PJI was 95.8%. Conclusion. Complex two-stage surgical treatment using resection arthroplasty with a non-free muscle flap transfer at the stage of debridement and subsequent revision has demonstrated high efficiency in eliminating the infectious process as well as restoring weight-bearing capacity and extremity function. It could be recommended as a method of choice in the treatment of patients with DTT PJI of hip joint.

An omental flap may become an alternative treatment for muscle flap or an effective treatment for RVF. [ABSTRACT FROM AUTHOR]

Chronic post‐pneumonectomy empyema (CPPE) associated with bronchopleural fistula (BPF) is a potentially fatal complication and remains a surgical challenge. This study aims to propose a treatment protocol for managing this severe disease. From July 2009 to June 2021, 47 CPPE with BPF patients were treated in our department. CT scan with 3D reconstruction was used to detect BPF and to evaluate the location and volume of empyema cavity. Different surgical techniques were used to close BPFs according to they sizes. Multiple pedicled muscle flaps were chosen to fill the empyema cavity, and among them, latissimus dorsi (LD) was the mostly used flap. For cases that regional flaps were not suitable, free flaps were used. Patients were followed‐up from 7.9 to 102.8 months. Forty‐four patients (93.6%) healed after the operation. Closure of BPFs failed in three patients (6.4%), leading to regional infection. These patients were treated by bronchoscopic application of sealants, continuous drainage and antibiotics, and they eventually healed. Total or partial flap loss was not seen in any of the cases. Treatment protocol was proposed based on these results. CT scan with 3D reconstruction is an effective examination to evaluate pleural cavity defect and BPF. Proper technique to close the BPF and right choice of flap to fulfil the empyema cavity are the two most important key points to treat CPPE associated with BPF patients. [ABSTRACT FROM AUTHOR]

BackgroundThe World Health Organization guidelines for management drug resistant tuberculosis include surgery as an additional method in selected cases. Pneumonectomies have higher risk of morbidity such as bronchial fistulas which may be prevented by bronchial stump covering. We compare two methods of bronchial stump reinforcement.Methods and materialsA retrospective single center follow-up study was done in 52 patients who underwent pneumonectomy for drug resistant pulmonary tuberculosis. Between 2000 and 2017 we performed pneumonectomies with pericardial fat reinforcement of bronchial stump in group 1 (n = 42), and between 2017 and 2021 in group 2 with pedicled muscle flap reinforcement group 2 (n = 10).ResultsBronchial fistulas occurred in 17/42 (41%) of patients group 1 and there was no fistula in group 2, and this was statistically different (Fisher's test p = 0.02). Post-operative complications were seen in 24/42 (57%) of the patients in Group 1, and 4/10 (40%) patients in Group 2 (Fischer's test p = 0.53). In group 1 positive bacteriology decreased from 74% to 24% just after surgery, and in group 2 it decreased from 90% to 10%, but this was not statistically different (Fisher's test p = 0.63). In group 1 no-one died the first month, but 8/42 (19%) died within a year; in group 2 one died within a month, and only this death (10%) within a year. This difference in case fatality was not statistically significant.ConclusionsThe use of pedicle muscle flap for bronchial stump coverage during the pneumonectomies for destructive drug resistant tuberculosis can prevent severe postoperative fistulas and improve postoperative life.

Case Summary: A cat aged 12 years and 7 months was referred to a multidisciplinary hospital for investigation of feline injection site sarcoma (FISS) on the left thoracolumbar region. A CT examination of the mass revealed a multi-lobulated mass affecting the body wall, extending from the level of lumbar vertebrae L2 to L4. The mass was excised with 5 cm lateral margins, including resection of the 13th left rib, the caudal edge of the latissimus dorsi (LD) muscle, full-thickness abdominal wall and sections of the lumbar epaxial muscles. To reconstruct the defect, a combination of muscle flaps was used. This included diaphragmatic advancement and lateralisation, rotation of the LD, and creation of transposition flaps from the internal abdominal oblique and external abdominal oblique muscles, ensuring closure without tension. Skin closure required mobilising an inguinal flank fold flap. The cat was discharged from hospital 3 days postoperatively. Histopathology confirmed a diagnosis of FISS with clean wide margins. A gradual return to normal activity and complete healing of the surgical site was reported on follow-up, with one minor complication related to the skin flap (bruising at the base of the inguinal flank fold flap)., Relevance and Novel Information: This report describes the use of the aforementioned combination of muscle flaps to close a major abdominal wall defect in a cat with an excellent outcome. Practitioners can consider this technique when planning tissue reconstruction after FISS resection., Competing Interests: The authors declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article., (© The Author(s) 2024.)

Background: Management of sternal wound infections (SWIs) in pediatric patients following congenital heart surgery can be extremely difficult. Patients with congenital cardiac conditions are at risk for complications such as sternal dehiscence, infection, and cardiopulmonary compromise. In this study, we report a single-institution experience with pediatric SWIs.Methods: Fourteen pediatric patients requiring plastic surgery consultation for complex sternal wound closure were included. A retrospective chart review was performed with the following variables of interest: demographic data, congenital cardiac condition, respective surgical palliations, development of mediastinitis, causative organism, number of debridements, presence of sternal wires, and choice of flap coverage. Primary endpoints included achieved chest wall closure and overall survival.Results: Of the 14 patients, 8 (57%) were diagnosed with culture-positive mediastinitis. The sternum remained wired at the time of final flap closure in eight (57%) patients. All patients were reconstructed with pectoralis major flaps, except one (7%) who also received an omental flap and two (14%) who received superior rectus abdominis flaps. One patient (7%) was treated definitively with negative pressure wound therapy, and one (7%) was too unstable for closure. Six patients developed complications, including one (7%) with persistent mediastinitis, two (14%) with hematoma formation, one (7%) with abscess, and one (7%) with skin necrosis requiring subsequent surgical debridement. There were three (21%) mortalities.Conclusions: The management of SWI in congenital cardiac patients is challenging. The standard tenets for management of SWI in adults are loosely applicable, but additional considerations must be addressed in this unique subset population. [ABSTRACT FROM AUTHOR]

Introduction  An anatomical study was conducted to test a modified C-shaped flap designed for patients undergoing a keyhole approach and/or minicraniotomy for retrosigmoid approach (KRSA). Materials and Methods  Ten heads specimens were used. The surgical technique investigated was based on a 4-cm C-shaped skin incision with medial convexity (placed 8 cm laterally to the external occipital protuberance, with the lower edge terminating 1.5 to 2 cm above the mastoid tip), which followed by careful subperiosteal dissection and completed by reflecting and securing the skin flap layer anteriorly and the muscle flaps superiorly and inferiorly by stitches. Anatomical findings, including depth of surgical corridor till to the cerebellopontine cistern (CPC) as well as the sparing of neurovascular structures, were evaluated in every specimen. Results  Twenty surgical approaches to CPC were conducted, resulting in a short working distance to the target (32 mm) without any need for a self-retaining retractor. In every specimen, the integrity of occipital muscles and cutaneous nerves was maintained, and a solid multilayer closure was always achieved. These data suggest that landmarks-based design of this C-shaped incision could be helpful in avoiding damages to the soft tissues encountered during KRSA. Conclusion  This modified approach provides a wide surgical corridor to access the CPC while ensuring the minimal invasiveness of the standard S-shaped incision. Compared with the latter, it preserves better the integrity of the surrounding soft tissues and appears less likely to cause any iatrogenic injury to occipital muscles and cutaneous nerves.

ObjectiveThis study aimed to propose a novel surgical method via combination of fat graft and paraspinal muscle flap, in order to treat cerebrospinal fluid (CSF) leak during posterior thoracolumbar surgery. The clinical outcomes were also evaluated.MethodsData of a total of 71 patients who were diagnosed with intraoperative incidental durotomy and CSF leak after posterior thoracolumbar surgery in our hospital form January 2019 to January 2021 were retrospectively collected and analyzed. Among them, 34 and 37 patients were assigned into conventional suturing (CS) group and fat graft and paraspinal muscle flap (FPM) group, respectively. Patients’ demographic and clinical data were compared between the two groups.ResultsThe average drainage tube time in the FPM group was 3.89 ± 1.17 days, which was shorter than that in the CS group (5.12 ± 1.56, P

Recurrence of carpal tunnel syndrome implies the reappearance of symptoms after release surgery. If the cause of recurrence is not an incomplete release, but a traction neuritis, the tendency is to add to the revision surgery of the carpal tunnel the use of flaps to cover the median nerve. These flaps establish a physical barrier between the nerve and the rest of the adjacent structures, preventing adhesions, and providing neovascularization and better nerve sliding. In the present work, we detail a revision surgery in which the first lumbrical muscle is used as a covering flap. This flap has two benefits. Firstly, it acts as a vascularized coverage for the median nerve (avoiding the formation of fibrosis and favoring its sliding); secondly, a structure that takes up space is removed from the carpal tunnel, thus reducing the pressure within it. Along with the explanation of the technique, the present article provides a detailed description of the anatomical variability of the first lumbrical muscle and its vascularization, as well as the results of a cadaveric study on the location of the vascular pedicle of the first lumbrical muscle.

Background Little is known about the sensate recovery of skin grafts over free non-neurotized muscle flaps. The aim of this study was to evaluate the sensitivity of free gracilis muscle flaps and meshed skin grafts without nerve coaptation. Methods Thirteen consecutive patients with a median age of 55 years (range, 21–70 years) who underwent lower extremity reconstruction between September 2014 and October 2016 were included. Complications, flap contour, skin perception, and sensate recovery were assessed. Results All flaps survived completely. In one patient, wound dehiscence and infection occurred 1 month after surgery. After a median follow-up of 14 months (range, 10–51 months), a satisfactory contour and skin perception were achieved. The Semmes-Weinstein (SW) monofilament test (154.8±22 g) and static two-point discrimination (2-PD) (12.6±0.7 mm) showed intermediate recovery compared to the surrounding site (41% and 76%, respectively). There was an intermediate correlation between flap size and sensate recovery (2-PD: r=0.27, P=0.36; SW test: r=0.45, P=0.12). Vibration sensation recovered to 60%, whereas thermal sensation remained poor (19% at 5°C and 25% at 25°C). Conclusions Finer sensation could be partially restored. However, thermal sensation remained poor.

Zenker's traction diverticulum is a potentially fatal complication of anterior cervical spinal surgery which is likely under-reported. It is managed by medical stabilization, surgical abscess drainage, hardware removal, cricopharyngeal myotomy, and diverticulectomy with or without muscle flap interposition. We present two cases of Zenker's traction diverticulum perforation with spinal hardware erosion and infection, both of which opted for the muscle flap interposition. Given the inevitable scarring of the esophagus from the hardware and the low risk and significant benefit associated with a flap, a preemptive sternocleidomastoid flap at the time of the anterior spinal hardware may help reduce the growing burden of complication.

(1) Background: Lower extremity microvascular reconstruction aims at restoring function and preventing infection while ensuring optimal cosmetic outcomes. Muscle (M) or fasciocutaneous (FC) free flaps are alternatively used to treat similar conditions. However, it is unclear whether one option might be considered superior in terms of clinical outcomes. We performed a meta-analysis of studies comparing M and FC flaps to evaluate this issue. (2) Methods: The PRISMA guidelines were followed to perform a systematic search of the English literature. We included all articles comparing M and FC flap reconstructions for lower limb soft tissue defects following trauma, infection, or tumor resection. We considered flap loss, postoperative infection, and donor site morbidity as primary outcomes. Secondary outcomes included minor recipient site complications and the need for revision surgery. (3) Results: A total of 10 articles involving 1340 patients receiving 1346 flaps were retrieved, corresponding to 782 M flaps and 564 FC flaps. The sizes of the studies ranged from 39 to 518 patients. We observed statistically significant differences (p < 0.05) in terms of donor site morbidity and total flap loss with better outcomes for FC free flaps. Moreover, the majority of authors preferred FC flaps because of the greater aesthetic satisfaction and lesser rates of postoperative infection. (4) Conclusion: Our data suggest that both M and FC free flaps are safe and effective options for lower limb reconstruction following trauma, infection, or tumor resection, although FC flaps tend to provide stronger clinical benefits. Further research should include larger randomized studies to confirm these data. [ABSTRACT FROM AUTHOR]

Abstract Background Gastro-tracheobronchial fistula after esophagectomy is a rare but life-threatening complication associated with high mortality. Several authors reported postoperative management of tracheobronchial fistula. However, treatment is demanding and challenging, and the strategy is still controversial. Case presentation A 64-year-old man underwent thoracoscopic esophagectomy with two-field lymph node dissection and gastric conduit reconstruction by an intrathoracic anastomosis for esophageal cancer at a local hospital in June 2013. After surgery, a gastro-tracheal fistula and a gastro-bronchial fistula of the left main bronchus were diagnosed, and the patient was referred to our hospital for the management of the gastro-tracheobronchial fistula. CT and bronchoscopy and esophagogastroduodenoscopy performed at our hospital revealed that the gastro-bronchial fistula of the left main bronchus was cured by packing with the omentum from the gastric conduit and the gastro-tracheal fistula located 3 cm above the carina remained open. We concluded that the fistula would not resolve without further surgical procedure. However, such an operation was expected to be difficult and to need much time due to severe adhesion among the gastric conduit and/or trachea, bronchus, lung, and chest wall. Therefore, a two-stage operation was planned for safety and outcome certainty. The first operation was performed to close the fistula in October 2013. The gastric conduit was separated from the trachea and resected; then, the fistula was sutured and covered by intercostal muscle and latissimus dorsi muscle flaps. A month after the first operation, reconstruction with pedunculated jejunum was performed via the percutaneous route. The patient’s postoperative course was uneventful. Conclusion If the omentum is not observed between the gastric conduit and the tracheobronchus when a gastro-tracheobronchial fistula occurs after esophagectomy, surgeons should perform surgical treatment because conservative treatment is unlikely to cure. During surgery, the use of two types of muscle flaps, such as the intercostal muscle and the latissimus dorsi muscle flaps, is helpful for the closure of gastro-tracheobronchial fistulas.
