The role of vein grafts in reconstructive head and neck microsurgery

Abstract Objective: Free tissue transfer is widely used for head and neck reconstruction. In certain circumstances, vein grafting is required to elongate free flap pedicles to connect them to appropriate recipient vessels. Because of controversy regarding the use of interposition vein grafts in free tissue reconstruction, this paper reports vein graft indications, techniques, safety, and outcomes for head and neck microvascular surgery. Methods: Twenty-six patients (23 men and 3 women) who underwent interposition vein grafting concurrent with free tissue transfer were included in this study. The most common reason for head and neck reconstruction with vein graft was tumor recurrence, followed by flap salvage. The interposition vein grafts were applied in two manners as temporary arteriovenous (A-V) loop and conduit to extend the length of the free flap for venous drainage. Results: The most common reconstructions were anterolateral thigh flaps (15 cases), followed by vastus lateralis myocutaneous (3 cases) and radial forearm (2 cases) flaps. The common recipient vessels were superior thyroid artery, superficial temporal artery and external jugular vein. The free flap loss rate was 7.7% with vein grafts and 4.9 without vein grafts (p = 0.380). The free flap complication rate was 50.0% and 16.8% in patients with and without vein grafts, respectively (p < 0.001). Radiation therapy, chemotherapy, prior neck dissection, and prior free flap transfer were more common in the vein graft group (all p < 0.001). The hospital stay was significantly longer for the vein graft group than for the non-vein graft group (29.5 vs. 19.0 days; p = 0.001). Conclusion: Overall free flap survival rates of 92.3% and 95.1% in the vein and non-vein graft groups, respectively - indicating the reliability of the vein grafts in challenging head and neck reconstructions, particularly in salvage cases and patients with multiple reconstructions. Level of evidence: Level 3.

Sandwich graft technique outcomes in medium and large size nasal septal perforations / Resultados da técnica de enxerto sanduíche em perfurações do septo nasal de médio e grande porte

Abstract Introduction: Surgical treatment of medium and large sized nasal septal perforation is challenging. Techniques with and without interposition grafts are used. Objective: The aim of this study is to explain how we apply the sandwich graft technique that we use in medium and large nasal septal perforations as well as to present the results. Methods: We retrospectively reviewed the patients who were operated with the sandwich graft technique between January 2014 to December 2018 and followed up for at least 6 months. The demographic data, symptom scores, examination, and surgical findings of the patients were taken from the hospital records. Surgical outcomes were presented according to both perforation etiologies (idiopathic or iatrogenic) and sizes (Group A: < 2cm, Group B: ≥ 2 cm). Results: We reviewed 52 cases and 56 surgeries. The average diameter of the perforations was 19.2 mm. The success rate after initial surgeries was 84.6% (44/52). After 4 revision surgeries, the perforation was closed in 88.5% of the cases (46/52). Success rates for Group A and Group B were 90.0% and 86.4%, respectively (p = 0.689). The success rates in idiopathic and iatrogenic cases were 93.3% and 86.5%, respectively (p = 0.659). Conclusion: This study showed that the success rate of sandwich graft technique was higher in medium-sized perforations than large-sized ones and in idiopathic perforations compared to iatrogenic ones, but the latter rate was not statistically significant. This demonstrated that perforation size was not as important in the sandwich graft technique as in flap techniques.

Resumo Introdução: O tratamento cirúrgico da perfuração do septo nasal de médio e grande porte ainda é um desafio. Várias técnicas são usadas, com e sem enxertos de interposição. Objetivo: Descrever o uso da técnica de enxerto sanduíche que usamos nas perfurações de septo nasal de médio e grande porte e apresentar os resultados. Método: Revisamos retrospectivamente os prontuários de pacientes que foram operados com a técnica de enxerto sanduíche entre janeiro de 2014 e dezembro de 2018, com acompanhamento por pelo menos seis meses. Os dados demográficos, escores de sintomas, exames e achados cirúrgicos dos pacientes foram extraídos dos registros hospitalares. Os resultados cirúrgicos foram apresentados de acordo com as etiologias (idiopática ou iatrogênica) e os tamanhos da perfuração (Grupo A: < 2cm, Grupo B: >2cm). Resultados: Revisamos 52 casos e 56 cirurgias. O diâmetro médio das perfurações foi de 19,2 mm. A taxa de sucesso após as cirurgias iniciais foi de 84,6% (44/52). Após quatro cirurgias de revisão, a perfuração foi fechada em 88,5% dos casos (46/52). As taxas de sucesso para os Grupos A e B foram, respectivamente, 90,0% e 86,4% (p = 0,689). As taxas de sucesso nos casos idiopáticos e iatrogênicos foram, respectivamente, 93,3% e 86,5% (p = 0,659). Conclusão: Este estudo mostrou que a taxa de sucesso da técnica de enxerto sanduíche foi maior nas perfurações de médio porte do que nas de grande porte e nas perfurações idiopáticas do que nas iatrogênicas, mas sem significância estatística. Esse dado demonstrou que o tamanho da perfuração não foi tão importante na técnica de enxerto sanduíche quanto nas técnicas com uso de retalho.

Abstract: Hallux rigidus is the degenerative pathology of the metatarsophalangeal joint of the hallux. This pathology causes pain and decreased movement. There are multiple surgical treatments for this pathology, all with their respective indications. We present the case of a 54-year-old patient diagnosed with hallux rigidus who had only the lateral aspect of the metatarsal head affected. This patient was treated with a novel surgical procedure, performing an interposition hemiarthroplasty using the hallucis brevis extender associated with a cheilectomy and exostectomy. The patient had a favorable clinical evolution with improvement evidenced by clinical scales, with resolution of the symptoms and without complications. Interposition hemiarthroplasty using the extensor hallucis brevis is a successful joint and movement preservation treatment for hallux rigidus in young patients with lateral unicompartmental involvement of the metatarsal head, in whom it is important to preserve movement.

Objective:To evaluate the safety and efficiency of a modified double-tract reconstruction procedure─proximal gastrectomy with piggyback interposed jejunal single-channel reconstruction (PJIR-STR) for early SiewertⅡ adenocarcinoma of esophagogastric junction (AEG).Method:Data of 8 SiewertⅡ AEG patients at Shanxi Tumor Hospital and undergoing PJIR-STR from May 2018 to Oct 2019 were retrospectively analyzed. The gastroesophageal reflux disease questionnaire (GerdQ) was used to score the patients at 3, 6, 12, and 18 months after surgery. The severity of postoperative reflux esophagitis was assessed by gastroscopy at 3, 6 months after surgery, using the Los Angeles Classification criteria.Result:All patients recovered well after surgery without serious complications. No obvious gastroesophageal reflux was observed in all patients at different periods (All of the GerdQ scores were <8 points.) The results of gastroscopy showed that 1 patient was diagnosed as grade B reflux esophagitis at 3, 6 months after surgery, which was responsive to conservative treatment, and the other 7 patients had no grade B or above reflux esophagitis.Conclusion:PJIR-STR is a feasible, safe reconstruction with excellent efficiency of dual anti-reflux for the SiewertⅡ AEG.

Interposition urethroplasty for glandular hypospadias and severe penile curvature / 中华实用儿科临床杂志

Objective:To evaluate the therapeutic efficacy of interposition urethroplasty on glandular hypospadias and severe penile curvature.Methods:A total of 9 cases of congenital glandular hypospadias and 2 cases of congenital severe penile curvature (>30°) treated with the interposition urethroplasty technique in the Shenzhen Children′s Hospital from November 2008 to December 2019 were retrospectively analyzed.The mean age of initial surgery was 40 (25-109) months.Two cases were surgically treated with one-staged interposition urethroplasty and the remaining were treated with two-staged interposition urethroplasty.They were followed up for 8 months to 12 years, including the penile morphology, urination, urethrocutaneous fistula, urethral stricture and uroflowmetry.Continuous variables were presented as ± s deviation, Student′s t-test was used for comparison between groups. Results:The median length of interposition urethra was 3.2 (2.2-4.2) cm.The cosmetic appearance of penis was good without residual chordee, urethral stricture or urethral diverticulum in all patients.Two cases had urethrocutaneous fistula(one-staged repair and two-staged repair were performed in one case respectively), which were successfully repaired by re-operation.The maximum of uroflowmetry in patients at 3 months [(8.3±1.0) mL/s] and 6 months [(6.7±1.9) mL/s] after surgery was significantly lower than that of children in healthy control group [(10.5±3.7) mL/s] ( t=3.221, 3.864, all P<0.05). However, there was no significant difference in 1-year maximum of uroflowmetry postoperatively between surgically treated patients [(10.5±3.7) mL/s] and healthy control group ( P>0.05). Conclusions:Interposition urethroplasty is an effective and safe treatment for glandular hypospadias and/or severe penile curvature in children.

Management of Complex Hand Injuries with Suspension Interposition Arthroplasty and Carpometacarpal Joint Buttress Plating Based on Intra-operative Creativity and Flexibility: A Case Report

@#A young patient presented to our centre with swollen right hand following a motor vehicle accident. He was diagnosed with closed fractures of trapezoid, ulnar three metacarpal bones, radial styloid and ulnar styloid. The hand injuries were complicated with compartment syndrome. Emergent fasciotomy and application of external fixator of the hand were performed. Definitive fixation of the fractures was delayed due to the wound care post fasciotomy. During the definitive fixation of the hand, the trapezoid was found to be comminuted and completely extruded. Abundant callus was found at the fracture sites of the metacarpal bones. Anatomic fixation was not feasible. Principle-based intra-operative creativity and flexibility were of great significance in the unconventional fixation of the complex hand injuries described in this case report.

Iso-peristaltic colonic loop interposition for the treatment of benign oesophageal stricture: a case report with review of literature

Corrosive oesophageal strictures are a common and debilitating condition in India. Patients generally have dysphagia, cachexia, drooling of saliva, aspiration pneumonitis, and lung abscess. Though endoscopic dilatations are done in cases of short segment strictures, surgical oesophageal by pass is the permanent solution for this condition. A 24 years female presented with complaints of dysphagia and cachexia, due to corrosive stricture. Patient had a history of poison ingestion 2 years back. Intra-operatively stricturous mucosa is excised and an iso peristaltic colonic loop by pass was carried out. Post operatively patient had a complication of anastomotic leak which was treated conservatively, excepting which patient is symptom free and gaining weight on a follow up period of 1 year. Ever since first described by Kelling and Vuillet in 1911 colonic interposition is mostly used around the globe for oesophageal bypass in both benign and malignant conditions. Stomach and jejunum are the other conduits that can be used. Iso peristaltic loop is mostly used to reduce the incidence of reflux. Right colon or transverse colon graft based on the mid colic artery or the left colic artery owing to the reliable blood supply and less diameter. This procedure has a high complication rate of around 27% most of which are due to the vascular comprise of the graft.

Current results of arterial injuries seen at femoral and popliteal arteries in civil society

Background: Lower extremity arterial injuries caused by penetrating or fired-gun trauma may result in limb or loss of life. Early intervention has critical importance. The aim of this study was to investigate the importance of early intervention and outcomes.Methods: We retrospectively reviewed the data on 144 patients (18 females, 126 males) who were treated in Istanbul Medipol University Hospital between January 2016 to 2018. All patients had an arterial injury at level of femoral and popliteal arteries. Standard statistical methods were used for data analysis.Results: Revascularization was performed to all 144 (18 females, 126 males) patients. Autologous saphenous vein graft interposition was performed in 96 patients. End-to-end repair was performed in 39 patients. 9 patients underwent a polytetrafluoroethylene graft (8 mm ringed) interposition.Conclusions: All viable limbs should be revascularized rapidly. The primary goal is to provide bleeding control rapidly and to prevent the prolongation of ischemic time. It should be kept in mind that in addition to surgical technique, fasciotomy may be required in arterial injuries with ischemic time of more than 6-8 hours.

Irreducible Knee Dislocation with Vastus Medialis Muscle Interposition

Knee dislocation is one of the rare orthopedic emergencies that require special management with an annual incidence rate of less than 0.02%. Knee dislocations are classified by Kennedy, according to the direction of tibial dislocation in relation to the femur, as anteromedial, posteromedial, anterolateral, and posterolateral. Operative intervention and multi-ligament reconstruction are usually required in knee dislocation. Interposition of the vastus medialis inside the joint of a dislocated knee is an uncommon scenario where reduction becomes impossible. In this report, we present a case of irreducible knee dislocation with vastus medialis muscle interposition. Before reduction, we performed arthroscopy of the knee and removal of the interposed muscle to prevent extravasation of the fluid by sealing the torn capsular area.

Colonic Intramucosal Cancer in the Interposed Colon Treated with Endoscopic Mucosal Resection: A Case Report and Review of Literature

Colon interposition is a surgical procedure used for maintenance of luminal conduit after esophagectomy. Although epithelial neoplasia, such as adenoma and adenocarcinoma, may develop in the interposed colon, there are only few case reports on the condition. Due to the rarity of this condition, there is no definite consensus on recommending screening endoscopy for the early detection of neoplasia in the interposed colons. Here, we report a case of intramucosal adenocarcinoma in an interposed colon. Initial endoscopic resection for this tumor failed to accomplish complete resection. A subsequent endoscopic resection was performed 1 month later and complete resection was achieved. Based on our experience and recommendation on screening endoscopy for gastric cancer in Korea, we suggest that regular screening esophagogastroduodenoscopies should be performed following esophagectomy to detect early neoplasia in the stomach and interposed colon and avoid adverse results induced by delayed detection.

Luxación de la articulación interfalángica proximal del hallux con interposición de un hueso sesamoideo: una revisión bibliográfica / Dislocation of the proximal hallux interphalangeal joint with interposition of a sesamoid bone: a blibliographic review

Resumen: La luxación irreductible de la articulación interfalángica del hallux es una patología poco frecuente y hay pocos casos descritos. Se presenta como una luxación dorsal con interposición del sesamoideo; éste puede ser radiológicamente indetectable. Reportamos el caso de un paciente de 29 años que tras un traumatismo deportivo presentó una luxación interfalángica del hallux que pasó desapercibida hasta el octavo día. Al igual que en varios casos descritos en la literatura, no se pudo realizar una reducción cerrada, por lo que se procedió a una reducción abierta por una incisión dorsal. Una revisión bibliográfica revela que existen varias opciones terapéuticas, al igual que múltiples tipos de abordajes, y que estas lesiones generalmente presentan un buen pronóstico.

Abstract: The irreducible dislocation of the hallux interphalangeal joint is an infrequent condition and only a few cases have been described. It presents as dorsal dislocation with interposition of the sesamoid bone, which has the possibility of being radiologically undetectable. We present the case of a 29 year-old patient who, after a sports trauma sustained a hallux interphalangeal dislocation that went unnoticed for eight days. Since, closed reduction was not possible, as occurred in several cases reported in the literature, open reduction was performed through a dorsal incision. Based on a bibliographic review, it is possible to state that there are several treatment options and multiple approaches, and that these lesions usually have a good prognosis.

Glenohumeral interposition of rotator cuff stumps: a rare complication of traumatic rotator cuff tear / Interposição dos cotos do manguito rotador na articulação glenoumeral: uma complicação rara da lesão traumática do manguito rotador

Abstract The present report describes a case where typical findings of traumatic glenohumeral interposition of rotator cuff stumps were surgically confirmed. This condition is a rare complication of shoulder trauma. Generally, it occurs in high-energy trauma, frequently in association with glenohumeral joint dislocation. Radiography demonstrated increased joint space, internal rotation of the humerus and coracoid process fracture. In addition to the mentioned findings, magnetic resonance imaging showed massive rotator cuff tear with interposition of the supraspinatus, infraspinatus and subscapularis stumps within the glenohumeral joint. Surgical treatment was performed confirming the injury and the rotator cuff stumps interposition. It is important that radiologists and orthopedic surgeons become familiar with this entity which, because of its rarity, might be neglected in cases of shoulder trauma.

Resumo O objetivo deste trabalho é relatar um caso com os achados de imagem característicos da lesão traumática do manguito rotador com interposição de múltiplos cotos de tendões do manguito rotador entre a glenoide e o úmero, confirmada cirurgicamente. Esta condição é uma rara complicação do trauma do ombro. Em geral ocorre no trauma de alta energia, frequentemente associada com luxação da articulação glenoumeral. No caso em questão não houve documentação de luxação franca da articulação glenoumeral. As radiografias mostraram aumento do espaço articular, rotação interna do úmero e fratura do coracoide. Nas imagens de ressonância magnética, além das alterações observadas nas radiografias, foi identificada ruptura massiva do manguito rotador com interposição dos cotos dos tendões do supraespinal, do infraespinal e do subescapular no interior da articulação glenoumeral. Foi realizado tratamento cirúrgico confirmando a lesão e a interposição dos cotos do manguito. É importante que radiologistas e ortopedistas estejam familiarizados com esta entidade, que, pela sua raridade, pode ser negligenciada no atendimento do trauma do ombro.

Standardized surgical techniques for adult living donor liver transplantation using a modified right lobe graft: a video presentation from bench to reperfusion

After having experienced more than 2,000 cases of adult living donor liver transplantation (LDLT), we established the concepts of right liver graft standardization. Right liver graft standardization intends to provide hemodynamics-based and regeneration-compliant reconstruction of vascular inflow and outflow. Right liver graft standardization consists of the following components: Right hepatic vein reconstruction includes a combination of caudal-side deep incision and patch venoplasty of the graft right hepatic vein to remove the acute angle between the graft right hepatic vein and the inferior vena cava; middle hepatic vein reconstruction includes interposition of a uniform-shaped conduit with large-sized homologous or prosthetic grafts; if the inferior right hepatic vein is present, its reconstruction includes funneling and unification venoplasty for multiple short hepatic veins; if donor portal vein anomaly is present, its reconstruction includes conjoined unification venoplasty for two or more portal vein orifices. This video clip that shows the surgical technique from bench to reperfusion was a case presentation of adult LDLT using a modified right liver graft from the patient's son. Our intention behind proposing the concept of right liver graft standardization is that it can be universally applicable and may guarantee nearly the same outcomes regardless of the surgeon's experience. We believe that this reconstruction model would be primarily applied to a majority of adult LDLT cases.

Reconstitución de tránsito esofágico con interposición de colon derecho / Esophageal reconstruction using right colon interposition

Background: Esophageal replacement therapy is indicated for benign and malignant esophageal lesions and can be performed using stomach, jejunum or colon. Aim: To report the experience using right colon interposition for esophageal replacement. Material and Methods: Review of medical records of 41 patients aged 17 to 73 years (29 males), subjected to right colon interposition in the last 20 years. Indications, complications, mortality and long term results were recorded. Results: Forty nine percent of patients had a malignant esophageal lesion. Esophagectomy was performed using a transhiatal route or thoracotomy in 44 and 30 percent of patients, respectively. Retroesternal ascension was the most common route used in 88 percent of patients. The most common surgical complication was cervical fistula in 29 percent of patients, followed by fistula of the anastomosis between colon and jejunum in 7 percent of patients. Pneumonia was the most common medical complication. Postoperative mortality was 7 percent. Conclusions: The mortality in this series of patients is similar to that reported elsewhere.

Introducción: La cirugía de reemplazo esofágico actualmente se indica para tratamiento de enfermedades benignas y malignas del esófago. Existen diversas técnicas de reconstitución de tránsito esofágico que utilizan estómago, yeyuno o colon. Objetivo: Presentar la experiencia acumulada en el Hospital Clínico de la Universidad de Chile utilizando la técnica de transposición de colon derecho para la reconstitución de tránsito esofágico. Materiales y Métodos: Estudio descriptivo restrospectivo que incluyó a los pacientes sometidos a reconstitución de tránsito esofágico mediante interposición de colon derecho, durante los últimos 20 años, basado en la revisión sistemática de historias clínicas, analizando causas, morbilidad precoz y tardía, mortalidad operatoria, compararándolos con los resultados de la literatura. Resultados: Se incluyen 41 pacientes operados, con edad promedio de 63,6 años (17-73), 29 de ellos de sexo masculino (70,7 por ciento). El 48,7 por ciento correspondieron a neoplasias malignas, el resto a patología benigna. En 43,9 por ciento la esofaguectomía se realizó por vía transhiatal y 29,7 por ciento por toracotomía.

La complicación más frecuente correspondió a la fístula cervical en 29,3 por ciento seguida de la fistula en colo-yeyuno anastomosis en el 7,3 por ciento de los casos. La neumonía fue la complicación médica más frecuente (14,7 por ciento). La mortalidad postoperatoria fue 7,3 por ciento. Conclusión: El uso de interposición de colon derecho tiene indicaciones precisas. La mortalidad operatoria reportada se ajusta a lo encontrado en la literatura internacional.

A comparative study of fascial sheath interposition versus no fascial sheath interposition in No Scalpel Vasectomy.

Background: Since the introduction of male sterilization by surgery on deferens, several techniques have emerged to improve the results in terms of time, invasiveness, post operative infection, complications and success rate. Introduction: Vasectomy was introduced by Sharp in 1897. No scalpel vasectomy was introduced in China by Dr. Li Shun-Qiang in 1974. Intact fascial sheath helps in restoration of vas lumen and fascial sheath interposition prevents recanalization of vas by prevention of meeting of epithelialization from cut end of vas. Material and methods: The study was performed at PGIMS, Rohtak by performing surgery and follow-up up to one year of 326 subjects of no scalpel vasectomy. Clients were allocated in two groups. Group - A (155) with fascial sheath interposition and Group - B (171) without fascial sheath interposition. Surgeries were performed as a routine surgical procedure after full preparation of client including consent. Results: Majority of clients (56.1%) in Group - A were in age group 31-40 years followed by 22-30. years (28.4%), 41-50 years (14.8%) and 0.7% in age group more than 50 years. in Group - B, majority were also in age group 21-30 years (63.7%), followed by 31-40 years (29.8%), 41-50 years(5.9%) and 0.6% were of above 50 years. In Group - A, fascial sheath interposition was not possible in 17.2% clients due to non separation of sheath from vas. Sperm granuloma formation was observed in 8.6% in Group - A and 5.6% in Group-B. In comparison of 100% success rate in Group - A failure rate of 1.8% was observed in Group - B. Conclusion: The present study supports the existing literature that fascial sheath interposition adds a little more to the operating time of vasectomy, increases chances of wound infection and granuloma but has a less failure rate of vasectomy.
