Fechamento de comunicação bucossinusal com retalho de corpo adiposo de bochecha: relato de caso clínico / Closure of bucosinusal communication with cheek adipose body flap: Clinical case report

A comunicação bucossinusal (CBS) é uma complicação relativamente frequente na prática odontológica que ocorre em procedimentos cirúrgicos, principalmente, exodontias dos molares superiores. O diagnóstico dessa comunicação é feito através de exames clínicos intraorais, empregando a manobra de Valsava, e para a confirmação do diagnóstico, utiliza-se exame radiográfico. A literatura cita inúmeros métodos de tratamento, entretanto não evidenciam a técnica específica para cada caso, entre esses métodos existe o retalho com o corpo adiposo da bochecha, que apresenta alto índice de sucesso no fechamento das CBS. Quando a CBS é fechada incorretamente ou de forma tardia o paciente fica propício a desenvolver quadros de sinusite crônica ou aguda, além de fístulas bucossinusais. Portanto, deve-se identificar e tratar essa comunicação de imediato para evitar o desenvolvimento de outras complicações. O objetivo do presente trabalho é apresentar um caso clínico de um paciente com comunicação bucossinusal atendido na clínica odontológica da Unidade de Ensino Superior de Feira de Santana (UNEF), com a finalidade de demostrar a técnica cirúrgica utilizando a rotação do corpo adiposo da bochecha (Bola de Bichat).

The bucosinusal communication (BCS) is a relatively frequent complication in dental practice that occurs in surgical procedures, especially extractions of the upper molars. The diagnosis of this communication is made through intraoral clinical examinations, using the Valsava maneuver, and for the confirmation of the diagnosis, radiographic examination is used. The literature cites numerous methods of treatment, however they do not evidence the specific technique for each case, among these methods there is the graft with the adipose body of the cheek, which has a high success rate in the closure of the CBS. When the CBS is closed incorrectly or late, the patient is prone to develop chronic or acute sinusitis, in addition to bucosinusal fistulas. Therefore, this communication should be identified and treated immediately to prevent the development of other complications. The objective of the present study is to present a clinical case of a patient with bucosinusal communication attended at the dental clinic of Unidade de Ensino Superior de Feira de Santana (UNEF), with the purpose of demonstrating the surgical technique using the rotation of the adipose body of the cheek (Bichat ball).

Incidência de complicações durante os anos iniciais de formação de um serviço de fissuras labiopalatinas / Incidence of complications during the initial years of formation of a cleft lip and palate service

Introdução: A fissura labiopalatina é a malformação congênita craniofacial mais comum. Dificuldades na alimentação, fala e audição são comuns nestes pacientes, necessitando de tratamento multidisciplinar, o que dificulta a criação e manutenção de serviços especializados. A diversidade de classificações e o grande número de técnicas cirúrgicas utilizadas nas cirurgias primárias (queiloplastia e palatoplastia) dificultam a comparação de dados epidemiológicos e de complicações entre os serviços, existindo carência de estudos avaliando centros especializados em fissuras labiopalatinas recém-criados. Método: Foi realizado estudo do tipo coorte prospectiva com pacientes com diagnóstico de fissura labiopalatina submetidos a procedimentos cirúrgicos primários, no Hospital de Clínicas da Universidade Federal de Uberlândia, entre julho de 2017 e fevereiro de 2023. Foram incluídos pacientes menores de 18 anos com acompanhamento pós-operatório de pelo menos 3 meses. Resultados: Participaram do estudo 79 pacientes, que foram submetidos a 115 cirurgias primárias (54 queiloplastias e 61 palatoplastias). Foram relatadas 11 complicações neste período: 2 deiscências em queiloplastia (3,70%), 1 cicatriz hipertrófica em queiloplastia (1,85%), 6 fístulas em palatoplastia (9,83%) e 2 deiscências em palatoplastia (3,28%). A incidência de complicações foi de 9,56% quando analisado o total de cirurgias, sendo 5,55% nos pacientes submetidos a queiloplastia e 13,11% nos pacientes submetidos a palatoplastia. Conclusão: A incidência de complicações durante os anos iniciais de estruturação do serviço foi semelhante a outros estudos da literatura.

Introduction: Cleft lip and palate is the most common congenital craniofacial malformation. Difficulties in eating, speaking, and hearing are common in these patients, requiring multidisciplinary treatment, which makes it difficult to create and maintain specialized services. The diversity of classifications and the large number of surgical techniques used in primary surgeries (cheiloplasty and palatoplasty) make it difficult to compare epidemiological data and complications between services, and there is a lack of studies evaluating newly created specialized centers for cleft lip and palate. Method: A prospective cohort study was carried out with patients diagnosed with cleft lip and palate who underwent primary surgical procedures at the Hospital de Clínicas of the Universidade Federal de Uberlândia, between July 2017 and February 2023. Patients under 18 years of age with follow-up were included. post-operative period of at least 3 months. Results: 79 patients participated in the study, who underwent 115 primary surgeries (54 cheiloplasties and 61 palatoplasties). 11 complications were reported in this period: 2 dehiscences in cheiloplasty (3.70%), 1 hypertrophic scar in cheiloplasty (1.85%), 6 fistulas in palatoplasty (9.83%) and 2 dehiscences in palatoplasty (3.28%). The incidence of complications was 9.56% when analyzing the total number of surgeries, being 5.55% in patients undergoing cheiloplasty and 13.11% in patients undergoing palatoplasty. Conclusion: The incidence of complications during the initial years of structuring the service was similar to other studies in the literature.

Manejo Quirúrgico de Fístula Bucosinusal: Reporte de Caso y Revisión de la Literatura

Las fístulas bucosinusales son complicaciones poco frecuentes originadas a partir de comunicaciones bucosinusales de larga trayectoria o no tratadas que predisponen a desarrollar cuadros patológicos tales como infecciones, sinusitis y un establecimiento crónico de la fístula si no es tratada de manera apropiada y oportuna. El tratamiento indicado es el cierre quirúrgico de esta comunicación, la cual puede ser lograda mediante múltiples técnicas; siendo el tamaño, localización y compromiso de los tejidos blandos circundantes los factores principales para considerar una técnica por sobre otra. El siguiente artículo tiene como objetivo presentar el manejo de una fístula bucosinusal de larga data en un paciente de 71 años con antecedentes médicos de radioterapia de cabeza y cuello.

Oroantral fistulae are rare complications originating from non-treated or long-term oroantral communications which can contribute to the development of certain pathological entities such as local infections, sinusitis and chronic fistula formation. The treatment modality indicated is surgical closure of the communication, which can be achieved through multiple techniques, being the size, location and nearby soft tissue the main factors for considering one technique over another. The objective of the following article is to present the management of an oroantral fistula in a 71 year old patient with a medical history of head and neck radiotherapy.

Experiencia en el manejo de fístulas enterocutáneas postoperatorias en el Hospital Nacional del 2017 al 2022

Introducción: la mayoría de las fistulas enterocutáneas se producen como complicación de una o varias cirugías previas. La mortalidad sigue siendo muy elevada. Su tratamiento supone un reto para el cirujano y gran uso de recursos humanos, económicos y prolongada estancia hospitalaria. Objetivo: determinar la experiencia del manejo de las fístulas enterocutáneas postoperatorias en el servicio de cirugía general del Hospital Nacional de Itauguá durante el periodo 2017-2022. Metodología: estudio observacional descriptivo retrospectivo de corte transversal, con muestreo no probabilístico. Solo hubo 30 casos con fichas completas, las cuales sometimos a procesamiento y análisis de las variables de interés. Resultados: de la muestra final 70 % fueron hombres, el promedio de edad fue de 49,6 años y de días de internación 28,6. Solo 5 pacientes consultaron por secreción fecaloide, los demás refirieron secreción seropurulenta por herida o cicatriz operatoria. Del total, 9 fueron de alto débito. El 100 % recibió antibioticoterapia; obitaron 4 de los 14 pacientes intervenidos quirúrgicamente con fin terapéutico. La técnica quirúrgica mayormente utilizada fue: laparotomía + liberación de adherencias e identificación de la fístula + resección intestinal + anastomosis. De los antecedentes la mayoría fueron postoperados de oclusión intestinal mecánica alta o peritonitis aguda de origen apendicular. Conclusión: debido a su alto impacto en la capacidad laboral y social las fístulas enterocutáneas representan patologías quirúrgicas muy complejas y relevantes con bajas tasas de curación definitiva. La mayoría se presentan como complicación de cirugías de urgencia; requiere intervención multidisciplinaria adaptada para cada caso en particular.

Introduction: the occur enterocutaneous fistula as a complication of one or several previous surgeries. Mortality is still very high. Its treatment represents a challenge for the surgeon and great use of human and economic resources and a long hospital stay. Objective: to determine the experience in the management of postoperative enterocutaneous fistulae in the general surgery service of the Itauguá National Hospital during the period 2017-2022. Methodology: retrospective, cross-sectional, descriptive, observational study with non-probabilistic sampling. There were only 30 cases with complete records, which we subjected to processing and analysis of the variables of interest. Results: of the final sample, 70 % were men, the average age was 49,6 years and 28,6 days of hospitalization. Only 5 patients consulted due to fecaloid discharge, the rest reported seropurulent discharge from wound or surgical scar. Of the total, 9 were high debit. 100 % received antibiotic therapy, 4 of the 14 patients who underwent surgery as therapeutics, died. The most commonly used surgical technique was: laparotomy + release of adhesions and identification of the fistula + intestinal resection + anastomosis. Most of the antecedents were post-operated for high mechanical intestinal occlusion or acute peritonitis of appendiceal origin. Conclusion: due to their high impact on work and social capacity, enterocutaneous fistulas represent very complex and relevant surgical pathologies with low definitive cure rates. Most present as a complication in emergency surgeries; requires multidisciplinary intervention adapted to each particular case.

Manejo endovascular de hemoptisis secundaria a pseudoaneurisma de la aorta torácica, mediante un abordaje proximal

Objetivo: Describir un caso clínico y una alternativa de manejo para el tratamiento de la hemoptisis secundaria a patología la aneurismática de la aorta torácica. Materiales y Métodos: Revisión de historia clínica y exámenes complementarios, disponibles en sistema digital del centro asistencial de origen. Resultados: Se presenta el caso de paciente masculino, 56 años, que cursó con cuadro de hemoptisis, posteriormente objetivado como secundario a un pseudoaneurisma de la aorta torácica. Entre sus antecedentes destaca, enfermedad aorto-ilíaca tratada mediante un bypass de aorta torácica. Se decidió la reparación endovascular, mediante un abordaje proximal, utilizando la arteria axilar. Discusión: Las indicaciones para el uso de la reparación torácica endovascular de la aorta (TEVAR) se están expandiendo ampliamente, incluyendo a pacientes previamente intervenidos o aquellos que antiguamente se consideraban con un riesgo prohibitivamente alto para una cirugía. La fístula aorto-bronquial, es una complicación rara, sin embargo, existe correlación entre su desarrollo y la cirugía de aorta torácica. La sospecha diagnóstica debe ser alta. La AngioTC, cumple un doble rol, tanto para el diagnóstico, como para la planificación preoperatoria, hecho fundamental para conseguir una terapia adecuada.

Objective: To describe a clinical case and a management alternative for the treatment of hemoptysis secondary to thoracic aortic aneurysm pathology. Material and Method: Review of clinical history and complementary examinations, available in the digital system of the health care center of origin. Results: We present the case of a male patient, 56 years old, presented with hemoptysis, later found to be secondary to a pseudoaneurysm of the thoracic aorta. History included aorto-iliac disease treated by thoracic aortic bypass. Endovascular repair was decided by a proximal approach using the axillary artery. Discussion: Indications for the use of TEVAR are expanding widely. Including previously operated patients or those formerly considered prohibitively high risk for surgery. Aortobronchial fistula is a rare complication, however, there is a correlation between its development and thoracic aortic surgery. Diagnostic suspicion should be high. AngioCT plays a dual role in diagnosis and preoperative planning, which is essential to achieve adequate therapy.

Fístula pancreática: una complicación temida. Experiencia en una unidad de cirugía hepatobiliopancreática de cuarto nivel / Pancreatic fistula: A feared complication. Experience in a fourth level hepatobiliopancreatic surgery unit

Introducción. La fístula pancreática postoperatoria es una de las complicaciones más importantes en la cirugía hepatobiliopancreática. Su diagnóstico se hace mediante la presencia de un nivel de amilasa en el líquido de drenaje al menos tres veces por encima del valor de la amilasa en suero a partir del tercer día postoperatorio. El objetivo de este estudio fue caracterizar los pacientes con fístula pancreática postoperatoria en nuestra institución, evaluando la importancia de la detección temprana y el establecimiento de un manejo oportuno. Métodos. Estudio descriptivo, retrospectivo, que incluyó los pacientes sometidos a pancreatoduodenectomía, con diagnóstico de fístula pancreática postoperatoria como complicación de cirugía hepatobiliopancreática, en el Hospital Internacional de Colombia, en Piedecuesta, entre enero del 2017 y diciembre de 2020. Se excluyeron los pacientes con otro tipo procedimiento quirúrgico y aquellos que decidieron no participar en el estudio. Resultados. Se evaluaron 69 pacientes, con un predominio del sexo femenino (n=38; 55,1 %) y mediana de la edad de 57 años. El 33,3 % (n=24) de los pacientes intervenidos desarrollaron fístula pancreática postoperatoria, siendo el 23,2 % fuga bioquímica, grado B 8,7 % y grado C 2,9 %, para quienes se indicaron manejo expectante, control ecográfico y reintervención, respectivamente. Fallecieron 5 pacientes (7,2 %). Conclusiones. La fístula pancreáticapostoperatoria es una complicación para tener en cuenta en todos los pacientes sometidos a pancreatoduodenectomía. Existen estrategias que pueden permitir disminuir la incidencia de esta complicación, con el fin de mejorar el desenlace, el pronóstico y la morbilidad posquirúrgica.

Introduction. Postoperative pancreatic fistula is one of the most important complications in hepatobiliopancreatic surgery. Its diagnosis is made by the presence of an amylase level in the drainage fluid at least three times above the serum amylase value from the third postoperative day. The objective of this study was to characterize patients with postoperative pancreatic fistula at our institution, evaluating the importance of early detection and to establish a timely management. Methods. Descriptive, retrospective study that included patients who underwent pancreatoduodenectomy with a diagnosis of postoperative pancreatic fistula as a complication of hepatobiliopancreatic surgery at the Hospital Internacional Colombia, between January 2017 and December 2020. Patients with another type of procedure performed by this specialty and those who did not decide to participate in the study were excluded. Results. A total of 69 patients were included, the median age was 57 years with a predominance of females (n=38; 55.1%). 33.3% (n=24) of the operated patients developed postoperative pancreatic fistula, with 23.2% having a biochemical leak, grade B in 8.7% and grade C in 2.9%, for whom expectant management, ultrasound control and reintervention were indicated, respectively. Five patients died (7.2%). Conclusions. Pancreatic fistula is a complication to take into account in all patients undergoing pancreatoduodenectomy. There are strategies that can reduce the incidence of this complication and thus improve not only the outcome but also the prognosis and postoperative morbidity.

Fístula enterocutánea: un enfoque desde las generalidades y el estado nutricional / Enterocutaneous fistula: An approach based on generalities and nutritional status

Introducción. Una fístula es una conexión anormal entre dos superficies epitelizadas. Cerca del 80 % de las fístulas entero-cutáneas son de origen iatrogénico secundarias a cirugía, y un menor porcentaje se relacionan con traumatismos, malignidad, enfermedad inflamatoria intestinal o isquemia. La morbilidad y las complicaciones asociadas pueden ser significativas, como la desnutrición, en la que intervienen múltiples factores. Métodos. Se realizó una búsqueda de la literatura en las bases de datos de PubMed, Google Scholar y SciELO, utilizando las palabras claves descritas y se seleccionaron los artículos más relevantes de los últimos años. Resultados. La clasificación de las fístulas se basa en su anatomía, su gasto o secreción diaria y su localización. Existe una tríada clásica de las complicaciones: sepsis, desnutrición y anomalías electrolíticas. El control del gasto de la fístula, el drenaje adecuado de las colecciones y la terapia antibiótica son claves en el manejo precoz de estos pacientes. Los estudios recientes hacen hincapié en que la sepsis asociada con la desnutrición son las principales causas de mortalidad. Conclusiones. Esta condición representa una de las complicaciones de más difícil y prolongado tratamiento en cirugía abdominal y colorrectal, y se relaciona con importantes tasas de morbilidad, mortalidad y altos costos para el sistema de salud. Es necesario un tratamiento multidisciplinario basado en la reanimación con líquidos, el control de la sepsis, el soporte nutricional y el cuidado de la herida, entre otros factores.

Introduction. A fistula is an abnormal connection between two epithelialized surfaces. About 80% of enterocutaneous fistulas are of iatrogenic origin secondary to surgery, and a smaller percentage are related to trauma, malignancy, inflammatory bowel disease or ischemia. The associated morbidity and complications can be significant, such as malnutrition, in which multiple factors intervene. Methods. A literature search was carried out in the PubMed, Google Scholar and SciELO databases using the keywords described and the most relevant articles from recent years were selected. Results. The classification of fistulas is based on their anatomy, their daily secretion output, and their location. There is a classic triad of complications: sepsis, malnutrition and electrolyte abnormalities. Control of fistula output, adequate drainage of the collections and antibiotic therapy are key to the early management of these patients. Recent studies emphasize that sepsis associated with malnutrition are the main causes of mortality. Conclusions. This condition represents one of the most difficult and prolonged complications to treat in abdominal and colorectal surgery, and is related to significant rates of morbidity, mortality and high costs for the health system. Multidisciplinary treatment based on fluid resuscitation, sepsis control, nutritional support, and wound care, among other factors, is necessary.

¿Es la técnica de la ligadura del trayecto fistuloso interesfintérico (LIFT) la mejor alternativa para el tratamiento de la fístula anorrectal compleja?

La fistulotomía es aceptada como la técnica ideal en el tratamiento de la fístula anorrectal (FA) simple con porcentajes de curación superiores al 95% y mínimo daño al aparato esfinteriano, a pesar de que la técnica, por definición, incluye la sección inmediata de la porción distal del esfínter interno. En la FA compleja, el daño potencial a la continencia es una secuela temida, lo que ha motivado la búsqueda de múltiples alternativas terapéuticas, algunas dificultosas y/o que requieren instrumentos sofisticados. La ligadura del trayecto fistuloso interesfintérico (LIFT) es una técnica conservadora que ha sido investigada en forma exhaustiva en los últimos 13 años con resultados variables. Se analiza las posibles causas de las fallas del LIFT (40% como promedio) y las variantes propuestas, incluyendo la técnica preferida del autor en los últimos 15 años, que se caracteriza por un abordaje interesfinteriano del trayecto fistuloso que permite tratar tanto el foco interesfintérico como el orificio fistuloso interno y las glándulas afectadas mediante una setón interesfintérico ajustado, más un pequeño drenaje cutáneo externo. Es un procedimiento simple, reproducible y con óptimos resultados en cuanto a curación, sin sección inmediata del esfínter interno y sin alteración de la continencia. A pesar de ser una técnica promisoria, con la información disponible, el LIFT no cumple con los requisitos para ser considerada como la técnica de elección en el tratamiento de la FA compleja.

Fistulotomy is the best surgical technique to treat a simple anal fistula with success in more than 95% of the cases and minor damage of anal continence. Complex anal fistula is a challenging problem due to higher recurrence rates and incontinence associated to surgical procedures. New methods have been developed for the management of complex anal fistula and some of them include complex procedure and/or the use of sophisticated instruments. Relapses are caused by reactivation of the infection at the internal fistula orifice. This is left untreated by some technique including LIFT, a promising conservative technique that has shown success rates between 20% to 86%. We analyze the probably causes of the failure of LIFT and some variations proposed, including the alternative techniques of intersphincteric approach plus treatment of the pathological anal glands with immediate section of the internal sphincter. In the experience of the author over 15 years, the intersphincteric approach to the fistulous tract, the treatment of the internal fistula orifice with a loose seton and a small cutaneous drainage is the safest technique to cure the complex fistula anal with no damage to anal continence. The benefits of conservative techniques like LIFT must be counterbalanced with the relative high recurrence rates. The quality of current evidence is not good enough to consider LIFT as the gold standard in the treatment of complex anal fistula.

A systematic review on phased surgical management of in-testinal fistula / 中国现代普通外科进展

Objective:To summarize the surgical management experience on intestinal fistula(IF)patients with phasedtherapy and staged operation.Methods:Retrospectively analyzing the clin-ical data of 255 IF patientsin Beijing Tsinghua Changgung Hospital from January 2016 to December 2019,including age,gender,primary disease,IF causes,IF locations,IF numbers,IF natures,IF times,IF diagnoses and evaluations,nutritional risks,nutritional support,and infection statuses.Ac-cording to the pathophysiological characteristics of IF patients,IF therapy included three phases:Phase Ⅰ(IF acute onset),Phase Ⅱ(IF stable maintenance),Phase Ⅲ(IF deterministic operation).The IF deterministic operation included one-stage operation and multi-stage operation.The relationship between strategies and effects were analyzed in each treatment stage.Results:All 141 patients in Phase Ⅰ entered into Phase Ⅱ,in which 112 cases received complete treatment,28 cases gave up,and 1 case died.In 112 caseswho received complete treatment,75 cases were cured(83.7％),37 cases remained infected.The 37 cases that remained infected were combined with the 114 cases who were primarily hospitalized at Phase Ⅲ,were classified into 151 cases who received IF deter-ministic operations,in which 134 cases received stage Ⅰ surgery,and 17 cases received multi-stage surgery.138 cases were cured(91.4％).Conclusion:Intestinal fistula patients could exhibit a better cure ratio throughphasestherapy,which include the acute onset phase,stable maintenance phase,and deterministic operation phase.It is important to classify IF patients into the correct phase and conduct the corresponding treatment.The staged operations are also the key to the intestinal fistula-surgical strategy.

Purpose To evaluate the diagnostic accuracy of abdominal plain scan and contrast-enhanced multi-slice CT after orally diluted iodide in time segment(Post-ODI ANCCE-MSCT)for gastrointestinal fistula(GIF)secondary to acute pancreatitis(AP).Materials and Methods A total of 108 patients with late AP in the prospective and continuously collected database of Hunan Provincial People's Hospital from January 2017 to December 2022 were retrospectively extracted.Their demographic information and clinical features were recorded and GIF were screened by Post-ODI ANCCE-MSCT.The comprehensive clinical diagnosis results within 5 days thereafter were used as reference standards.The sensitivity,specificity,positive predictive value,negative predictive value and accuracy of Post-ODI ANCCE-MSCT for diagnosing GIF secondary to AP were calculated using a four-cell table,and the consistency of the two methods was evaluated by Kappa test and McNemar's test.Results Sensitivity was 91.5%(95%CI 78.7%-97.2%),specificity was 98.4%(95%CI 90.0%-99.9%),positive predictive value was 97.7%(95%CI 86.5%-99.9%),negative predictive value was 93.8%(95%CI 84.0%-98.0%),and the accuracy was 95.4%(95%CI 91.4%-99.3%),respectively.The Kappa value was 0.905,and P value was 0.375 via McNemar's test.Conclusion Post-ODI ANCCE-MSCT can diagnose GIF secondary to AP in a simple,non-invasive,rapid and accurate way,and provide earlier,more accurate and reliable image basis for clinical diagnosis and treatment.

A preliminary clinical study of polyester spacer-enhanced pancreatico-intestinal anastomosis in pancreaticoduodenectomy / 中华肝胆外科杂志

Objective:To investigate the safety and utility of using polyester spacers in conventional pancreatico-enteric anastomosis in pancreaticoduodenectomy to achieve prevention of postoperative pancreatic fistula.Methods:The clinical data of 82 patients with pancreaticoduodenectomy completed by the same physician in Anyang People's Hospital from August 2018 to August 2023 were retrospectively analyzed, including 52 males and 30 females, aged (62.21±9.75) years. They were divided into two groups, test group ( n=40) and control group ( n=42) according to whether polyester spacers were used in pancreatico-intestinal anastomosis, the perioperative data of the two groups were compared, and Logistic analysis was used to analyze the risk factors affecting postoperative pancreatic fistula. Results:There was no statistically significant difference between the two groups in terms of biliary fistula, intestinal fistula, abdominal infection, abdominal bleeding, and postoperative mortality rate (all P>0.05). The incidence of postoperative pancreatic fistula in the test group was 20.0% (8/40) which was lower than that in the control group 45.2% (19/42), and the difference was statistically significant ( P=0.015). Soft pancreas texture ( OR=16.595, 95% CI: 1.891~145.657) was an independent risk factor for postoperative pancreatic fistula, while improved pancreatic enterostomy with polyester spacers ( OR=0.332, 95% CI: 0.114~0.969) could reduce the risk of postoperative pancreatic fistula. Conclusion:Use of polyester spacers to reinforce the pancreatico-enteric anastomosis during pancreaticoduodenectomy reduces the incidence of postoperative pancreatic fistulae with good safety and practicality.

Objective:To investigate the clinical significance of intraoperative prepositioning of dual mediastinal drains in elderly patients developing anastomotic leakage(AL)after a total endoscopic Ivor-Lewis procedure.Methods:This retrospective case-control study analyzed the clinical data of 500 elderly patients who underwent total endoscopic Ivor-Lewis surgery for esophageal or cardia cancer from January 2020 to December 2022.In the control group, one mediastinal drainage tube was placed intraoperatively, while in the study group, two mediastinal drainage tubes were placed.Both groups had a chest tube placed conventionally.The study compared the incidence of anastomotic leak(AL)at 1 month postoperatively, inflammatory indexes in patients with AL, grading of AL, rate of nasal fistula placement, incision infection, anastomotic stenosis, and incidence of hoarseness.Additionally, it compared ICU occupancy, ventilator use, and ICU length of stay between the two groups.Results:The analysis included clinical data from 455 elderly patients.Among the patients who developed AL, the study group had significantly lower peak body temperature[(39.58±1.03)℃ vs.(38.05±0.56)℃, t=4.298, P<0.05], white blood cell count[(18.63±3.35)×10 9/L vs.(14.28±2.78)×10 9/L, t=3.450, P<0.05], and C-reactive protein(CRP)levels[(154.66±41.64)mg/L vs.(122.19±31.29)mg/L, t=2.131, P<0.05]. The study group also had a significantly lower grading of AL and rate of nasal fistula placement(82.4% vs.30.0%, P<0.05). In terms of ICU indicators, the study group had a significantly lower ICU admission rate(64.7% vs.10.0%, P<0.05), shorter period of ventilator use[(6.47±8.15)days vs.(0.90±2.23)days, t=2.62, P<0.05], and shorter ICU stay[(11.70±8.89)days vs.(4.70±6.27)days, t=2.184, P<0.05]. Conclusions:Double mediastinal drainage tubes, have been found to significantly alleviate inflammation, decrease the rate of nasal fistula placement and ICU admission, and shorten the length of ICU stay in elderly patients.Therefore, they are considered safe and deserving of clinical promotion.

The application of gracilis flap in repair of radiation-induced vesicovaginal fistula / 中华泌尿外科杂志

Objective:To investigate the effect of gracilis flap in repair of radiation-induced vesicovaginal fistula.Methods:The data of 18 patients with radiation-induced vesicovaginal fistula treated in the Sixth People’s Hospital Affiliated to Shanghai Jiaotong University School of Medicine from March 2021 to August 2022 were retrospectively reviewed. Their age was (57.3±10.4) years. All patients underwent radical surgery for cervical cancer, and received (24.6±2.8)(range from 20 to 30)times of radiotherapy after surger. The median time between the end of radiotherapy and the onset of vesicovaginal fistula was 14.0(7.8, 18.2)months. The median duration of fistula urine was 12.0(9.8, 18.0)months. All patients were required to use median 19.5(15.8, 27.5) pads per day before surgery. The life quality score(QOL)of 18 cases was median 5.0(5.0, 6.0) points. Three cases had performed laparoscopic vesicovaginal fistula repair, two cases had underwent transvaginal vesicovaginal fistula repair, one case had underwent transvaginal and laparoscopic vesicovaginal fistula repair successively, and the remaining 12 cases were new vesicovaginal fistulas. Two cases were combined with rectovaginal fistulas. All patients underwent the repair of vesicovaginal fistula with gracilis flap interposition in prone and folded knife position, by transvaginal route, the vesicovaginal fistula was mobilized and the two layers were closed, and the vascular pedicle gracilis flap of left inner leg was romoved under the skin tunnel to repair the vesicovaginal fistula. Meanwhile, two cases combined rectovaginal fistulas were repaired and closed the rectovaginal fistulas. The urinary catheters were removed at 3 weeks after the operation and urination was recorded.Results:All patients underwent smooth surgery in (96.6±13.2) minutes. The median follow-up was 13.0(9.8, 20.2)(range from 6 to 24)months. The median number of urine pads used per day in 18 patients was 2.0(1.0, 11.8), and significantly reduced ( P<0.01).QOL score was median 1.0(0, 4.2) point and significantly reduced ( P<0.01).Successful outcome was achieved in 12 patients with no leakage of urine in the vagina. Two cases developed urinary incontinence and required conservative treatment, but the curative effect was poor. Two cases still had vaginal urine leakage performed vesicovaginal fistula repair again. One case was successfully repaired without significant urine leakage.The other case still had significant urine leakage and the QOL score was 3 points. She refused further treatment for self-satisfied. Two cases still had vesicovaginal fistula and rectovaginal fistula after the surgery, and refused further surgery. Conclusions:Repair with gracilis flap interposition is a surgical method with few complications and reliable surgical effect for patients with radiation-induced vesicovaginal fistula.
