Sexual health outcomes after penile reconstruction in the exstrophy–epispadias complex

The penis in exstrophy-epispadias complex (EEC) males is diminutive and patients are often dissatisfied with appearance and length. Due to an increased risk of psychosexual dysfunction, patients desire penile reconstruction. Surgical options include penile lengthening with a full thickness skin graft (SG) or tissue expansion (TE) used for cutaneous coverage or neophalloplasty using a radial forearm free flap or pedicled antero-lateral thigh flap. The aim of this study was to assess sexual health outcomes before and after SG or TE assisted lengthening and neophalloplasty. Patients aged 18 years or older, who underwent penile reconstruction were identified using an institutionally approved database of EEC patients. Patient perception of penile appearance, sexual function, their frequency of sexual intercourse and overall satisfaction with reconstruction were assessed using a survey consisting of validated and non-validated questions. Eighty-three patients underwent penile reconstruction, 57 met the inclusion criteria and 28 responded to the survey (49.1%). Fourteen were reconstructed using a SG, 6 with TE and 8 underwent neophalloplasty. Median time from reconstruction to survey completion was 4.4 years (range 1.2-13.2) Four patients had a diagnosis of epispadias, 1 cloacal exstrophy, 23 classic bladder exstrophy (CBE). Before reconstruction patients were dissatisfied with their penile appearance with a median penile perception score of 4.5 compared to 7.5 after surgery (p=0.0034, Fig.1). Twenty-three patients were dissatisfied with penile length, with 18 reporting an improvement following reconstruction (p=0.0002). There was no correlation in time after reconstruction with PPS or satisfaction with penile length (p=0.86 and p=0.55, respectively). Overall, the median Sexual Health Inventory for Men (SHIM) score was 19, with no difference between the surgical groups (p=0.33). Nine patients engaged in sexual intercourse before reconstruction which increased to 17 afterwards. All three surgical methods improved patient perception of penile appearance and length. Patients who previously never engaged in intercourse were able to and those who had were doing so more frequently, of which a greater proportion were in a relationship. The results are encouraging though must be interpreted with caution due to the small number of responders and possible risk of bias. These findings provide vital information for future patients and routine psychological assessment will help manage patient expectations to improve satisfaction.

Novel design for local full-thickness skin graft: optimizing donor sites of radial forearm free flap.

Donor site deformities remain the primary issues after radial forearm free flap (RFFF) translocations. This study introduced a local full-thickness skin graft (FTSG) from an adjacent cutaneous area to manage RFFF donor sites and evaluated the esthetic and functional outcomes post-operatively. This was a retrospective study among patients undergoing ablative surgery for head and neck tumors followed by defect reconstruction using a RFFF. The RFFF donor site defects were covered by local FTSGs from the adjacent skins whose harvesting was assisted by a forearm model or traditional FTSGs from abdomen. The color matching degree, surgical scars, ranges of wrist movement, and grip strengths in donor forearms were assessed in two groups at twelve months after surgery. Patients undergoing local FTSGs recovery exhibited better color matching than those repaired by traditional FTSGs from the abdomen. In forearm model, the local FTSGs width should be less than 22% of the forearm circumference located 5cm away from the center of Fossa cubitalis. All the local FTSGs transplanted with this technique showed primary or secondary healing. This study demonstrated using this innovatively designed local FTSGs to close RFFF donor sites was more advantageous than traditional methods.

A 31-year review of composite radial forearm free flaps for head and neck reconstruction

The aim of this study was to report the patient characteristics and radial fracture rates in a consecutive series of composite radial forearm free flap (CRFFF) for head and neck reconstruction over a 31-year period. The patients were identified from between 1990 to 2020 inclusive from theatre records and records from previous analyses at the Unit on free flap outcomes. Electronic case notes were accessed where available, to gather information on the operation, histopathology, and radiographs. Patients were categorised into three groups for analysis: (1) new oral cancers with a composite radial being the first choice of flap, (2) new oral cancers with a composite radial being the choice of flap following compromise of another bony flap, (3) osteoradionecrosis (ORN) cases. There were 103 CRFFF cases, median (IQR) age 69 (59-80) years, comprising 78 (Group 1), 5 (Group 2) and 20 (Group 3). The CRFFF failure rate was 6% (6/103) and the radius fracture rate was also 6% (6/103), both with 95% confidence interval 2.2-12.2%. Of the 6 radius fractures, 1 underwent surgical management (rush nailing), 1 died in hospital and the others managed with cast immobilisation. Two-year overall survival after surgery for the103 patients was 54% (SE 5%), while 5-year survival was 40% (SE 5%). In conclusion, in spite of the familiarity with other bone flaps such as fibular free flap, DCIA, scapula, and the limited bone stock and potential fracture related morbidity associated with the CRFFF, this flap still has a place in the surgical reconstructive armamentarium.

Clinical outcomes for microvascular reconstruction in oral cancers: experience from a single surgical centre.

Reconstruction of a surgical defect is an important part of the management of oral cancers. Microvascular free flap construction provides better functional and cosmetic outcomes. Between 2014 and 2020, some 524 patients underwent microvascular reconstruction. Comorbidity variables were scored using the Charlson Comorbidity Index (CCI). Complications were recorded using Clavien-Dindo criteria. Eighty-three (15.84%), 339 (64.69%) and 102 (19.47%) patients underwent free radial forearm flap, free anterolateral thigh flap and free fibula osteocutaneous flap (FFOCF), respectively. Clavien-Dindo complications of grade III and above were seen in 39 (7.44%) patients. Total flap loss was seen in 18 patients and of these, 16 were salvaged using alternative free flaps or pedicled flaps. On univariate analysis, overall and major complication rates were higher in FFOCF (p=0.171). Major complications significantly more common in patients with a CCI score >4 (p=0.001). Patients aged >65 years had higher rates of complications (p=0.03). Microvascular free tissue transfer is a reliable, safe and gold standard modality in surgical reconstruction and can be replicated in non-institutional settings.

The radial forearm snake flap: An underutilized technique for fasciocutaneous and osteocutaneous forearm flaps with primary closure

The radial forearm free flap (RFFF) is associated with troublesome donor site morbidity related to split thickness skin grafting (STSG). The radial forearm snake flap with primary closure of the donor site may reduce donor site complications. Single institution, retrospective cohort study comparing rates of delayed donor site wound healing and tendon exposure in 52 patients undergoing radial forearm snake flap and 95 patients undergoing conventional RFFF with STSG closure of the donor site. Tendon exposure occurred in zero (0%) patients undergoing snake flap and four (4.2%) patients undergoing conventional RFFF (0/52 vs. 4/95; p=0.297). Delayed wound healing occurred in zero (0%) patients undergoing snake flap and 19 (20.0%) patients undergoing conventional RFFF (0/52 vs. 19/95; p < 0.001). The radial forearm snake flap provides an alternative to conventional RFFF harvest, which enables primary donor site closure with reduced rates of delayed donor site healing.

Radial Forearm Free Flap Phalloplasty in Female-to-Male Transsexuals - A Comparison Between Gottlieb and Levine's and Chang and Hwang's Technique

BackgroundPhalloplasty is a crucial part of female-to-male genital gender-affirming surgery, however, up to date, there is still no standardized phalloplasty technique. AimTo evaluate the outcome of a single-center series of phalloplasties using the free radial forearm flap variations by Chang and Hwang vs by Gottlieb and Levine on a similar number of transgender patients. MethodsBetween 2018 and 2020, 45 female to male transgender patients underwent phalloplasty using a neuro-microvascular free radial forearm flap in our department. Twenty patients underwent phalloplasty by the use of the Chang and Hwang design, whereas 25 patients were subjects to a phalloplasty according to Gottlieb and Levine technique. Patients’ demographics, procedural characteristics, postoperative complications, and outcome of both groups were retrospectively evaluated and compared with each other. ResultsPatients’ demographics were similar in both groups. We did not observe relevant differences concerning postoperative complications comparing the two groups, except for the statistically significant lower rate of partial flap necrosis in the Gottlieb and Levine group. No statistically significant risk factors for an increase in complication rate could be identified. Urethral fistulas were the leading cause of revision. Clinical ImplicationOptimizing a phalloplasty surgical technique and contributing to establish the gold standard in phalloplasty. Strengths & LimitationThis retrospective study presents the first comparison between the free radial forearm flap phalloplasty by Chang and Hwang and by Gottlieb and Levine performed at the same department on a similar number of transgender patients published so far. ConclusionThe Chang and Hwang design is associated with a lower rate of urologic complications (fistulas, stenosis) while the Gottlieb and Levine design has a statistically significant lower incidence of partial flap necrosis. Future prospective trials are needed to establish the gold standard in phalloplasty.Spennato S, Ederer IA., Borisov K et al.

Reconstruction following transoral robotic surgery for head and neck cancer: Systematic review.

We performed a systematic review to characterize reconstructive modalities and postoperative surgical outcomes following TORS resection. A search of the PubMed, SCOPUS, and EMBASE databases was conducted to identify studies describing patients undergoing reconstruction of TORS defects. Twenty-six studies met inclusion criteria, consisting of 260 patients who underwent TORS resection followed by reconstruction. Twenty-one studies reported tumor classification information, with TORS performed for 44 (23.0%) T1, 86 (45.0%) T2, 33 (17.3%) T3, and 28 (14.7%) T4 tumors. Eighteen distinct reconstructive modalities were described in the studies identified, including nine unique free flap types. The most commonly performed reconstruction was the radial forearm free flap (RFFF), accounting for 121/260 (46.5%) of reconstructions performed. Reported surgical complications included 5 pharyngocutaneous fistulae, 13 hemorrhagic complications, 24 infectious complications, and 5 free flap failures. Our findings demonstrate favorable surgical outcomes but minimal quantitative functional data to compare reconstructive options following TORS.

International assessment of interobserver reproducibility of flap delineation in head and neck carcinoma

Background: Several reports have suggested that radiotherapy after reconstructive surgery for head and neck cancer (HNC), could have deleterious effects on the flaps with respect to functional outcomes. To predict and prevent toxicities, flap delineation should be accurate and reproducible. The objective of the present study was to evaluate the interobserver variability of frequent types of flaps used in HNC, based on the recent GORTEC atlas. Materials and methods: Each member of an international working group (WG) consisting of 14 experts delineated the flaps on a CT set from six patients. Each patient had one of the five most commonly used flaps in HNC: a regional pedicled pectoralis major myocutaneous flap, a local pedicled rotational soft tissue facial artery musculo-mucosal (FAMM) (2 patients), a fasciocutaneous radial forearm free flap, a soft tissue anterolateral thigh (ALT) free flap, or a fibular free flap. The WG’s contours were compared to a reference contour, validated by a surgeon and a radiologist specializing in HNC. Contours were considered as reproducible if the median Dice Similarity Coefficient (DSC) was > 0.7. Results: The median volumes of the six flaps delineated by the WG were close to the reference contour value, with approximately 50 cc for the pectoral, fibula, and ALT flaps, 20 cc for the radial forearm, and up to 10 cc for the FAMM. The volumetric ratio was thus close to the optimal value of 100% for all flaps. The median DSC obtained by the WG compared to the reference for the pectoralis flap, the FAMM, the radial forearm flap, ALT flap, and the fibular flap were 0.82, 0.40, 0.76, 0.81, and 0.76, respectively. Conclusions: This study showed that the delineation of four main flaps used for HNC was reproducible. The delineation of the FAMM, however, requires close cooperation between radiologist, surgeon and radiation oncologist because of the poor visibility of this flap on CT and its small size.

Effect of tongue reconstruction following hemiglossectomy on articulation and speech intelligibility

This study is aimed to investigate the articulatory functions of patients who have undergone tongue reconstruction following hemiglossectomy. The second aim of the study is to compare the speech intelligibility between hemiglossectomy patients who have undergone tongue reconstruction using pectoralis major myocutaneous with those hemiglossectomy patients who had undergone tongue reconstruction using radial forearm free flap.Fourteen patients who have undergone tongue reconstruction following hemiglossectomy as a treatment for oral cancer between the age of 30 to 60 years were taken up for this study. Tamil Articulation Test was used for assessing the articulatory functions of patients. The speech intelligibility of each patient was assessed using the Ali Yavar Jung National Institute for the Hearing Handicapped intelligibility rating scale. Analysis of articulatory errors revealed linguoalveolar consonants were more impaired when compared to other consonants. Patients with radial forearm free flap had somewhat better speech intelligibility compared to patients with pectoralis major myocutaneous flap reconstruction.The type of reconstruction also impacts the speech intelligibility. Effective intervention can be planned based on the comprehensive speech evaluation and analysis of articulatory error relative to place and manner of production.

Assessment of Speech and Deglutition in Patients with Carcinoma Tongue Post Radial Forearm Free Flap Cover.

Over the past 30years, the introduction of reconstructive techniques incorporating microvascular free tissue transfer has transformed the quality of life of patients undergoing head and neck surgery.The free forearm flap was first described for head and neck reconstruction by Yang in 1981 when he used this flap to reconstruct a neck defect secondary to a burn scar contracture.In this retrospective cohort study, we have evaluated patients who underwent reconstruction of hemiglossectomy defect with radial forearm free flap for malignancy of tongue, from year 2018 to 2020, with reference to deglutition and speech.As per the data obtained, 41.7% and 50% of the patients had achieved excellently intelligible speech and moderately intelligible speech respectively whereas only 8.3% had poorly intelligible speech. On evaluation of post operative swallowing, 83.4% of the patients had excellent swallowing score and the remaining 16.6% had moderate and poor swallowing score.Hence, reconstruction of hemiglossectomy defects with radial forearm free flap is an excellent method to restore the functional outcomes in speech and deglutition.

Speech and swallowing function following microsurgical reconstruction of palatal defects in a series of six pediatric patients.

Reconstruction of extensive palatal defects in growing patients aims to restore speech intelligibility and swallowing function while avoiding excessive scarring formation that may cause growth disturbances in the palate and midface region. Free flaps transfer healthy, well-vascularized tissue to the defect area, and their combination with pharyngeal flaps allow for restoration of the velopharyngeal function. We examined speech and swallowing after microsurgical palate reconstruction in a series of six pediatric patients. Radial forearm free flaps were used in all cases, in combination with a superiorly based pharyngeal flap in five cases. Mean age at surgery was 10.7 years. Etiologies included recurrent oronasal fistula due to failed primary cleft palate repair (n=4), embryonal rhabdomyosarcoma of the maxilla (n=1), and inflammatory fibrous hyperplasia (n=1). Speech evaluations (with the Hirose standard and listener ratings) and swallowing assessments (based on videofluoroscopy swallowing studies and patient-reported swallowing and diet) were performed in average 44 months postoperatively. All flaps survived without major postoperative complications. Speech intelligibility was graded as "excellent" in four patients and "moderate" in two. Hypernasality and nasal obstruction were each judged as "none/minimal" in five cases and "moderate" in one case. All patients tolerated oral diet without significant nasal regurgitation. In five of six patients, the swallowing assessment showed good motion and velopharyngeal closure. Microsurgical reconstruction of extensive palatal defects using radial forearm free flap, with or without a superiorly based pharyngeal flap, is a reliable technique that can deliver substantial improvement of speech and swallowing in pediatric patients.

Comparison of Outcomes of the Radial Forearm Free Flap Vs Pectoralis Major Pedicled Flap for the Reconstruction of Oral Soft Tissue Defects

Introduction: Head and neck cancers are one of common cancers with peri oral cancers are more prevailing in areas with use of tobacco, ghutka and alcohol. Peri oral soft tissue defects can occur after tumor ablation or trauma. Objectives/Aim: To assess the flap survival and oral competence in radial forearm free flap versus pedicled pectoralis major myocutaneous flap. Method: A randomized control trial was conducted at Department of Plastic Surgery BVH, Bahawalpurfrom July 2019 to December 2020. A total of 60 patients were randomly divided in two equal groups. In Group A, radial forearm free flap and in Group B pedicledpectoralis major myocutaneous flap were used for reconstruction offull thickness defects. Data was entered and analyzed by using SPSS version 27.0. Mean and Standard Deviation were calculated for quantitative variables. Frequency and percentages were calculated for qualitative variables.Chi-square test was used to compare the flap survival and oral competence between the groups and p 0.05 which is not statistically significant. Results: The mean age of patients in group A was 47.47 ± 12.28 years and in group B was 48.40 ± 12.02 years. Out of 60 patients, 80%&amp; 60% of patients in group A &amp; B were males respectively. Partial Flap lossin group A was 6.67% and in Group B 10%. Overall flap survival was 93.33% in Group A &amp; 86.67% in Group B with the p &gt; 0.05 which is not statistically significant. Conclusion: Radial forearm free flap is comparable option for head and neck reconstruction to the pectoralis major myocutaneous flap with fewer complication rate and overall successful outcome.

Bone Union of Osseous Microvascular Free Tissue Transfer in Mandibular Reconstruction.

ObjectivesOsseous microvascular free tissue transfer (MFTT) is the gold standard for reconstruction for most segmental mandibulectomy defects. The most common osseous MFTT utilized in reconstruction is the fibular, scapular, and osteocutaneous radial forearm (OCRF) free flap. We evaluated postoperative bone union as well as clinical complications following MFTT and the impact of various patient and reconstructive characteristics, including type of osseous MFTT.Study DesignRetrospective cohort study.SettingTertiary care academic hospital.MethodsThis study examined patients who underwent osseous MFTT for mandibular defects from January 2017 to January 2019.ResultsAn overall 144 osteotomies in 58 patients were evaluated. Of the 144 junctions, 28 (19.4%) showed radiographic nonunion. Patients who underwent preoperative (odds ratio [OR] = 0.30, P = .027) and postoperative (OR = 0.28, P = .003) radiation had a significantly lower bone union score. Time from surgery to postoperative imaging was associated with higher bone union scores (OR = 1.07, P = .024). When bone union scores were compared among types of MFTT, fibular (OR = 5.62, P = .008) and scapular (OR = 4.69, P = .043) MFTT had significantly higher scores than OCRF MFTT. Twelve (20.7%) patients had postoperative complications. There was no statistically significant correlation between clinical complications and various variables, including type of osseous MFTT.ConclusionPre- and postoperative radiation and time from surgery have an impact on bone union. Regarding the type of MFTT, fibular and scapular MFTT appeared to have higher bone union when compared with OCRF. There was no impact of bone union or type of osseous MFTT on clinical complications.

Comparison of Functional and Survival Outcomes in Pedicled and Microsurgical Flap Reconstruction for Near-Total and Total Glossectomies.

Introduction:Patients with advanced carcinoma tongue end up with near-total/total glossectomy (NTG/TG). We intended to compare functional, oncological, and survival outcomes of patients undergoing pedicled and microsurgical flap reconstruction in NTG/TG patients at our hospital.Methodology:A prospective study was conducted for 7 years on 91 patients with carcinoma tongue who underwent NTG/TG at our institute. Patients underwent anterolateral thigh (ALT), free radial artery forearm flap (FRAFF), and pectoralis major myocutaneous (PMMC) flap reconstruction and were followed up for immediate complications and functional outcomes for speech, swallowing, and decannulation after completion of adjuvant treatment and then for survival rates for a period of 60 months and statistically analysed with log rank test and Fisher’s exact test for correlation.Results:Ninety-one (42.85%) patients underwent NTG, while 57.14% underwent TG. 85% of patients had >5 mm margin, 14% had ≤ of 5 mm, and none were positive. 57% of patients did not have postoperative complications and 10% underwent re-exploration. During follow-up, 85.7% of patients were able to take orally: 52% soft diet and 32% liquid diet. Multivariate analysis of individual flaps, swallowing, and speech intelligibility values were significant. After 5 years of postadjuvant therapy, there was 76% overall survival, 11% local recurrence and 12% had regional recurrence.Discussion:Morbidity and functional outcome depends on the extent of resection. PMMC flaps can be done on lack of expertise. FRAFF has better functional outcomes owing to pliability of flap. ALT and other bulky flaps require expertise and are prone to flap-related complications. Planning of reconstruction should be based on the defect size together with counseling of patients regarding the risk of complications and delay in adjuvant therapy.

Paediatric oral caustic soda ingestion: Case series and lessons learned

Introduction: The ingestion of sodium hydroxide otherwise known as caustic soda causes devasting injuries. Oral complications include microstomia, fibrosis and trismus. We present a case series of paediatric oral caustic soda ingestion injuries and their management by the Oral Maxillofacial (OMFS) team at Royal Manchester Children’s Hospital and the lessons learnt from these cases. Methods: A total of 3 cases are presented. The patients had injuries when they were 20, 22, and 30 months old. Treatment modalities ranged from custom splinting, steroid infiltration, scar-release procedures, commissuroplasty, split thickness skin grafts and free tissue transfer. 2 patients were referred years post injury. 1 patient was referred acutely. Results: In one case a radial forearm free flap was used for reconstruction of the commissure and buccal mucosa after several failed contracture release procedures. This improved mouth opening removing reliance of PEG tube feeding. One case had severe injuries remains tracheostomy and PEG tube dependent with pending future reconstructive surgery at an older age. The final case was referred to our department early and custom splints have been used since the injury to maintain mouth opening with some success. Conclusions: Treatment of the complications of oral caustic soda ingestion in the paediatric population is challenging. The cases presented highlight that; relapse following contracture release is common and that in selected cases free tissue transfer can lead to satisfactory outcomes. We advocate early referral to an OMFS team in all cases of severe injury. Introduction: The ingestion of sodium hydroxide otherwise known as caustic soda causes devasting injuries.

Closure of radial forearm free flap donor-site defect with proportional local full-thickness skin graft: case series study of a new design.

ObjectivesThe aim of this study was to describe a simple, convenient, and reliable new technique using local full-thickness skin graft (FTSG) for skin coverage of a donor-site defect of the radial forearm free flap (RFFF).Patients and Methods Between April 2016 and April 2021, five patients with oral squamous cell carcinoma underwent mass resection combined with RFFF reconstruction. After RFFF harvesting, donor-site defects were restored by proportional local FTSG.ResultsThe donor-site defects ranged in size from 24 to 41.25 cm2, with a mean of 33.05 cm2. Good or acceptable esthetic outcomes were obtained in all five patients. There was no dehiscence, skin necrosis, wound infection, or severe scarring at the graft site through the end of the postoperative follow-up period, and no patient had any specific functional complaint.ConclusionThe proportional local FTSG showed promising results for skin coverage of the donor-site defect of the RFFF. This technique could decrease the need for skin grafts from other sites.

Comparison Between Radial Forearm Free Flap and Pectora is Major Myocutaneous Flap for Reconstruction in Oral Cavity Cancer Patients: Assessment of the Quality of Life

We aimed to evaluate the quality of life of Chinese patients after immediate reconstruction surgery on individuals with oral cavity cancer. In addition, we compared the differences between radial forearm free flap and pectoralis major myocuta- neous flap. Using the University of Washington quality of life v4 questionnaire, 1:1 matched research was performed on patients received PMM or RFF flap. Chi-square test was used to analyze the variables. One hundred twenty four of 179 questionnaires were returned (69.3%). Age, N stage, and postoperative radiotherapy were similar for both groups. However, there were significant differences between two groups in gender, T stage, operation duration, and complication rate. Oral cavity cancer patients reconstructed with radial forearm free flap had better shoulder and speech functions but worse appearance domains. The results of our research provide important information for patients and physicians during their discussion of treatment programs for oral cavity cancers.

Skin Color Match in Head and Neck Reconstructive Surgery.

To quantify the degree of color match achieved during microvascular facial reconstruction, and to describe a novel technique for improving reconstructive skin color match. We hypothesize that split-thickness skin grafts (STSG) placed atop de-epithelialized free tissue produces better facial skin color match than free tissue with intact epithelium. Cross sectional photographic study of reconstructed facial skin color match. Sixty-eight adults, who underwent head and neck reconstructive surgery, were divided into six categories based on cutaneous reconstructive technique: cervicofacial flap, radial forearm free flap (RFFF), fibula free flap, anterolateral thigh free flap (ALT), STSG over adiopofascial flap (STAFF), and STSG over myogenous flap (STMF). Averaged color samplings of the reconstructed defect and adjacent normal skin were taken from digital photographs. The color difference was calculated using the delta-E calculation. Blinded expert observers also rated the degree of color match. Nonparametric cohort contrast and correlation statistical analyses were performed. The mean delta-E's and 10-point Likert ratings for the ALT, fibula, RFFF, STAFF, STMF, and cervicofacial flaps were 11.6, 10.0, 7.7, 6.3, 8.8, and 4.7, and 5.1, 6.4, 2.4, 3.2, 2.7, and 1.1, respectively. Likert scale inter-rater correlation was strong, with coefficient=0.80. On average, STSG over de-epithelialized myogenous and adipofascial free tissue transfers produced a better color match than the skin paddles of donor sites, with the exception of the radial forearm donor site. Delta-E values obtained from photos correlated well with expert ratings of color match. This reliable technique for quantifying color match may be used in future studies. 3 Laryngoscope, 132:1753-1759, 2022.

Extracorporeal lung support for tracheoesophageal fistula surgical repair with free flap

Tracheoesophageal fistula results in persistent leakage of saliva into the trachea, prevents oral feeding, and predisposes to aspiration pneumonia. Large fistula closure may require a free flap to cover the defect. When the defect involves the tracheal area between the neck and the mediastinum, a tubeless field for optimal exposure can be advantageous. This article reports the use of veno-venous extracorporeal lung support, a known safe and efficient technique to support the patient’s respiratory function, for this purpose. The typical veno-venous extracorporeal lung support setting includes a femoro-jugular bypass. The patient cases reported here had characteristics that precluded the use of the jugular vein, such as neck radiation dermatitis, previous radical neck dissection, and poor accessibility. Therefore a more rarely described femoro-femoral approach was used. The cases of three patients with persistent tracheoesophageal fistula who had free flap surgeries (two bi-paddled radial forearm free flap and one latissimus dorsi muscle free flap) assisted by femoro-femoral veno-venous extracorporeal lung support are reported.
