RESUMO
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).

BACKGROUND: Endovascular embolization is frequently used for vascular lesions of the head and neck. Newer agents may help to enhance visualization and improve treatment outcomes. METHODS: The CLARIDAD clinical trial was a prospective, single center, first-in-man investigation of neurovascular embolization using the novel embolic agent ihtObtura for a broad indication, covering the need for a liquid embolic agent in head and neck procedures. The primary outcomes assessed were therapeutic efficacy to deliver ihtObtura to embolize the catheterized pedicle and associated angiographic vascularity, and subsequent loss of radiopacity. Safety endpoints included procedural adverse events, modified Rankin Scale (mRS) score, morbidity, and mortality. Radiologic and clinical follow-up evaluations were conducted at 30, 90, 180 days, and 1 year post-treatment. RESULTS: 65 consecutive patients (mean age 37.8 years, 50.8% women) were treated over 129 sessions. A total of 42 brain arteriovenous malformations (AVMs; 90% grades III and IV), 8 dural arteriovenous fistulas (DAVFs), and 15 hypervascular tumors were treated with ihtObtura using an average of 3.9 mL per session and 7.7 mL per patient. We achieved therapeutic effectiveness in 99% of catheterizations. Radiopacity loss was complete after 74.3% of the sessions at 30 days, 95.6% at 90 days, and 100% at the 1 year follow-up. Serious adverse events (mRS score >2) occurred in two patients (3.1%) with previously ruptured high grade AVMs leading to one death and one permanent disabling morbidity. CONCLUSIONS: The study showed that ihtObtura was a novel, safe, and effective liquid embolic agent for the treatment of AVMs, DAVFs, and hypervascular tumors. Its key property of significant radiopacity loss contributes to improve anatomical understanding, particularly in staged procedures, as well as reduction in post-procedural imaging artifact. There may be additional benefits of eliminating tantalum from the embolic mixture in terms of lesion penetration.
RESUMO
INTRODUCTION: Several studies associate the presence of higher serum concentrations of infliximab (IFX) with fistula healing in perianal Crohn's disease (CD). This study aimed to evaluate serum IFX concentrations in patients with perianal fistulizing CD (PFCD) in the presence or absence of general, clinical, and radiological activities. METHODS: This was a cross-sectional study in patients with PFCD during maintenance treatment with IFX from two centers. Serum IFX concentrations were measured before their next infusion and anal fistulas were evaluated by clinical examination and magnetic resonance imaging (MRI), whenever possible, performed 90 days before or after serum collection. According to clinical scores, radiological activity, and disease markers, patients were classified as in remission or active disease. Mean serum IFX concentrations were compared between the groups. RESULTS: Thirty-eight patients with PFCD were included. Demographic characteristics were similar in patients with remission or active disease. The overall mean serum IFX concentration of the entire sample (n = 38) was 5.21 ± 4.75 µg/mL (median 3.63; IQR 1.44-8.82). Serum IFX levels were 6.25 ± 5.34 µg/mL (median 3.62; IQR 1.95-11.03) in the 23 (60.5%) patients in remission and 3.63 ± 3.24 µg/mL (median 3.63; IQR 1.32-6.43; p = 0.226) in the 15 (39 .5%) who presented active disease. When evaluating general, clinical, and radiological activity of PFCD, and deep remission in isolation, no statistical difference between the groups was observed (p = 0.226, p = 0.418, p = 0.126, and p = 0.232, respectively). The 13 (34.2%) patients with an optimized dose of IFX had significantly higher serum concentrations than the remaining 25 (65.8%) with a standard dose: 8.33 ± 4.41 µg/mL (median 8.36; IQR 3.82-11.20) vs. 3.59 ± 4.13 µg/mL (median 1.97; IQR 1.18-3.85) -p = 0.002. Patients in remission and with an optimized IFX dose had significantly higher serum IFX concentrations than those with a standard dose (p = 0.006), whereas no significant difference was observed among those with active disease (p = 0.083). CONCLUSION: There were no differences in IFX serum concentrations in patients with clinical or radiological active PFCD as compared with those in remission. Patients with an optimized IFX dose had significantly higher serum concentrations than those with a standard dose. Patients in remission and with an optimized IFX dose had significantly higher serum concentrations than those with a standard dose.

OBJECTIVES: To use three-dimensional anorectal ultrasonography (3D-US) to evaluate the outcome of ligation of the intersphincteric fistula tract (LIFT) in patients with crypto-glandular transsphincteric fistula and describing the patterns of healing, failure, and recurrence rate. METHODS: After classifying the fistula and determining the length of the sphincter muscle to be transected, the patients were submitted to LIFT. The accuracy of pre- and postoperative 3D-US with 360° endoprobe (16 MHz) with automatic scanning and clinical findings was evaluated against surgical findings. Three outcomes were considered: healing, failure (persistent anal fistula through the original external opening or intersphincteric), and recurrence (reappearance of the anal fistula). RESULTS: Sixty-three patients of both sexes were evaluated. The 3D-US assessment revealed primary healing in 50 (79.3%) patients, although in 6 (9.5%) cases healing was delayed and the cavity was without communication with the anal canal. The procedure failed in 9 (15.9%) and fistula recurred in 4 (6.3%), all of whom underwent a second surgery based on a new 3D-US, resulting in a 92.3% (12/13) healing rate on 3D-US. CONCLUSIONS: A 3D-US was found to be useful in the preoperative assessment of fistulas by quantifying the percentage of muscle to be transected, and in the postoperative assessment by identifying healing, types of failure, and recurrence. The 3D-US was accurate and consistent with surgical findings.

OBJECTIVES: Oronasal fistulas are common sequelae following cleft lip and palate surgery and can significantly impact a patient's quality of life. They result from various factors, including surgical techniques, tissue management, and patient-specific factors. This case report explores the modern approach to oronasal fistula closure using periodontal plastic surgery principles. MATERIALS AND METHODS: The report presents two cases of patients with oronasal fistulas due to previous maxillofacial surgical intervention. These patients underwent microsurgical procedures that involved partial flap thickness preparation of the fistula areas, the use of connective tissue grafts from the palate, and meticulous suturing techniques to ensure graft integrity. The procedures were performed in stages, and postoperative care was provided. RESULTS: Both cases demonstrated successful fistula closure and graft survival. The patients reported improvements in breathing, speech, aesthetics, and quality of life. The second case also included guided bone regeneration and implant placement. CONCLUSIONS: Oronasal fistulas resulting from maxillofacial surgery can be effectively treated using periodontal plastic surgery techniques, significantly improving patients' quality of life and aesthetic outcomes. This approach represents a valuable addition to the existing repertoire of oronasal fistula closure methods.

Pancreaticopleural fistula is a rare complication of pancreatitis. We present a rare case of pancreaticopleural fistula in a 43-year-old alcoholic male. He presented with recurrent episodes of left pleural effusion that were managed with aspiration and chest tube placement. An MRI of the chest and upper abdomen revealed a pancreaticopleural fistula. The patient underwent distal pancreatectomy with splenectomy and Roux-en-Y pancreaticojejunostomy. The surgical approach was our first-line management due to the unavailability of octreotide and endoscopic retrograde cholangiopancreatography. His recovery was complicated by an empyema that was managed by tube thoracostomy and IV antibiotics. There was no issue detected at his 3-month follow-up clinic visit.
RESUMO
This image article presents an 88-year-old indigenous woman with a history of several episodes of abdominal pain, for which she went to numerous different hospitals in the countryside, was always treated with analgesics, and then discharged. After a long time, the patient eventually was evaluated with magnetic resonance imaging. The test revealed a displaced gallbladder with thickened walls, multiple stones, and a fistulous tract extending to the skin. This case underscores the significant challenges faced by patients in regions with limited healthcare access, highlighting the impact of delayed diagnosis and inadequate management on patient outcomes.
RESUMO
Introduction Submandibular gland fistula (SGF) is a rare subset of salivary gland fistulas. It is seldom tough to diagnose them prior to surgical exploration, and it is often clinically confused with close differentials. An early diagnosis based on pertinent clinical features and focused radiological findings can be pivotal in optimal management and help prevent recurrence and avoid unnecessary investigations/interventions. Objective To review articles that discuss SGF and provide vital etiological, clinical, and imaging features of this rare entity that can aid in early clinical diagnosis. Data Synthesis An extensive review involving PubMed and Google Scholar and reported in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) standards. Conclusion Submandibular gland fistula is a rare entity. It can be confused with close differentials, including branchial fistulas, if not thoroughly examined. Discharge from fistulae along with submandibular pain/tenderness and/or swelling are important diagnostic clues. A history of trauma, nodule at the site of discharge, prior submandibular disease/calculi, or discharge aggravated with food further increases a clinical suspicion. Optimal radiological investigation looking for calculi/foreign body and delineating the fistula tract is vital to affirm a diagnosis. Gland with fistula excision is a commonly advocated treatment of choice with no reports of recurrence, although conservative management and gland preserving surgery have also reported a favorable prognosis.

Pancreatic leaks occur when a disruption in the pancreatic ductal system results in the leakage of pancreatic enzymes such as amylase, lipase, and proteases into the abdominal cavity. While often associated with pancreatic surgical procedures, trauma and necrotizing pancreatitis are also common culprits. Cross-sectional imaging, particularly computed tomography, plays a crucial role in assessing postoperative conditions and identifying both early and late complications, including pancreatic leaks. The presence of fluid accumulation or hemorrhage near an anastomotic site strongly indicates a pancreatic fistula, particularly if the fluid is connected to the pancreatic duct or anastomotic suture line. Pancreatic fistulas are a type of pancreatic leak that carries a high morbidity rate. Early diagnosis and assessment of pancreatic leaks require vigilance and an understanding of its imaging hallmarks to facilitate prompt treatment and improve patient outcomes. Radiologists must maintain vigilance and understand the imaging patterns of pancreatic leaks to enhance diagnostic accuracy. Ongoing improvements in surgical techniques and diagnostic approaches are promising for minimizing the prevalence and adverse effects of pancreatic fistulas. In this pictorial review, our aim is to facilitate for radiologists the comprehension of pancreatic leaks and their essential imaging patterns.
RESUMO
Background and Purpose: To validate the scales of knowledge, attitude, and practice of self-care for arteriovenous fistulas in renal patients on hemodialysis. Methods: A methodological study verified the evidence of validity based on the content, response processes, and internal structure of the scales. The content was evaluated by six judges, and the response processes were verified with six patients. In the evaluation of the internal structure, the scales were applied to 220 patients for exploratory factor analysis with evaluation of McDonald's omega adjustment and calculation indexes. Results: The scales explained variance and McDonald's omega values of 40.4%/0.896, 60.7%/0.843, and 36.9%/0.702 for the knowledge (19 items), attitude (4 items), and practice (8 items), respectively. Conclusions: The scale of attitude was valid after the analysis of the content evidence, response processes, and internal structure. The arteriovenous fistula self-care knowledge and practice scales explained less than 50% of the constructs. Therefore, it is recommended that new studies be conducted to validate scales of knowledge and practice of fistula self-care.
RESUMO
Background: Atrio-oesophageal fistulas (AEFs) are an uncommon complication of pulmonary vein ablation, and its diagnosis is challenging. Multidisciplinary interventions and diagnostic imaging are usually required and may play a role in the initial assessment. Case summary: A 69-year-old female with atrial fibrillation who had undergone recent pulmonary vein ablation consulted with unspecific symptoms and sudden hemiparesis. Brain imaging showed pneumocephalus and acute infarcts. Chest computed tomography (CT) was highly suspicious for AEF. Surgical exploration revealed a swollen mediastinum attached to the right inferior pulmonary vein. Discussion: Non-specific symptoms after pulmonary vein ablation should prompt the suspicion of complications. In the presence of fever or neurological deficit, AEF must be suspected and assessed with a contrast-enhanced chest CT, which has become the gold standard. In brain imaging, pneumocephalus and multiple punctate acute infarcts might also indicate the presence of this complication.
RESUMO
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.
RESUMO
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.

Dural Arteriovenous Fistulas (dAVFs) of the anterior cranial fossa (ACF) are uncommon but carry a high risk of hemorrhage and pose substantial treatment challenges. Recent advancements in endovascular treatment (EVT), including the introduction of novel liquid embolic agents, have markedly bolstered EVT's role in managing ACF-dAVFs, with notable series published in the last five years. We aimed to assess the feasibility, safety, and efficacy of EVT for ACF-dAVFs. We searched Medline, Scopus, Web of Science, and Cochrane Library databases following PRISMA guidelines. Eligible studies included those with ≥ 5 patients undergoing embolization of ACF-dAVFs, detailing both angiographic and clinical outcomes. We used single proportion analysis with 95% confidence intervals under a random-effects model, I2 to assess heterogeneity, and Baujat and sensitivity analysis to address high heterogeneity. Publication bias was assessed by funnel-plot analysis and Egger's test. Outcomes included complete occlusion following embolization, unsuccessful endovascular embolization attempts, incomplete occlusion following embolization, symptom resolution or clinical improvement following embolization, recurrence; procedure-related complications, morbidity, and mortality. Additionally, a subanalysis for studies exclusively utilizing Onyx™ embolic system was done. Eighteen studies comprising 231 ACF-dAVF were included. Unsuccessful endovascular embolization attempts rate was 2%. Complete occlusion rate was 85%, with 4% of complications. Incomplete occlusion rate was 10%. Successfully embolized patients experienced either symptom resolution or clinical improvement in 94% of cases. Morbidity and mortality rates were 1% and 0%, respectively. Onyx subanalyses showed an overall rate of 0% for unsuccessful attempts, 95% for complete occlusion, and 5% for incomplete occlusion. Symptom resolution or clinical improvement was 98% and recurrence rate was 0%. EVT for ACF-dAVF is highly feasible, effective, and safe, with a low rate of complications, morbidity, and mortality. The subanalyses focusing on Onyx embolizations revealed superior efficacy and safety outcomes compared to the findings of the primary analyses involving all included studies.

BACKGROUND: Hemodialysis (HD) patients present an increased carotid intima-media thickness (CIMT) and calcified plaques, and studies have demonstrated that CIMT is predictor for cardiovascular death in this patient population; hence, the importance of identifying early non-invasive markers of atherosclerosis. We aim to propose a new three-perspective CIMT measuring method in HD population, and to further investigate the possible use and value of this method to predict outcomes. METHODS: A cross-sectional study was conducted, the CIMT was measured with duplex ultrasound during the perioperative access planning. Software provided maximum CIMT in a 10 mm (mm) width of the common carotid artery. CIMT was measured in Right (R) and Left (L) carotid arteries, both in anterior (a), lateral (l), and posterior (p) view. The sum of these values (Ra+Rl+Rp+La+Ll+Lp) was completed and termed as Sixth Carotid Intimal (SCI) score. We stratified either in low (summation <4) or high (>=4) SCI score groups. Demographics, patency rates, complications, and mortality were collected; chi-square test was used for our analysis. RESULTS: A total of 30 patients (mean age 49 years and 56% females) that underwent access creation in the upper arm from 2010 to 2016 were selected and studied. A low SCI score was found 19 patients and 11 had high SCI, no significant difference was observed in demographics, history cardiovascular disease, and clinical outcomes as early thrombosis, and primary, primary-assisted patency at 12 months. Interestingly, during the follow up period of 36 months a significant higher difference in late thrombosis rates occurred (63.6% vs 26.3%, p = .044) and a higher all-cause mortality (54.4% vs 15.7%, p = .025) in patients with SCI score group above 4. CONCLUSIONS: The SCI score method, might offer a screening tool for traditional cardiovascular risk factors in HD patients. In this study, we demonstrate an increased rate in late thrombosis and mortality in those with high SCI. Further research is necessary to better define the role of CIMT in vascular surgical procedures.
RESUMO
Introduction Enteroatmospheric fistulas (EAF) present significant challenges in surgical management due to their complex nature and high mortality rate. Traditional approaches often rely on prolonged parenteral nutrition, but emerging evidence suggests the potential benefits of enteral nutrition via fistuloclysis, an underappreciated enteral nutrition route. This study aims to evaluate the effectiveness of nutritional therapy, specifically fistuloclysis, in patients with EAF managed at the Trauma Unit of Santo Tomás Hospital, Panama. Methods A retrospective analysis was conducted on nine male patients diagnosed with EAF between January 2016 and December 2020. Data on demographics, fistula characteristics, and nutritional management were collected through chart review. Descriptive statistics were used for analysis. Results We analyzed nine patients, all of whom received enteral nutrition (EN) via fistuloclysis in a median of 5.5 days from the diagnosis of EAF. Seven patients required parenteral nutrition (PN) at the beginning. The use of specialized enteral formulas, supplemented with hydrolyzed proteins and medium-chain triglycerides, facilitated discontinuation of PN once 80% of nutritional requirements were met via the enteral route, and EN was continued until definitive surgery. The median duration of PN was 34 days. No adverse effects related to EN were observed, whereas complications such as central venous catheter infections were reported in all cases requiring PN. Conclusion Fistuloclysis is a viable and effective alternative to traditional PN in patients with EAF. Specialized nutritional strategies, including the use of semi-elemental formulas, contribute to improved outcomes and reduced complications. Early initiation and gradual increase in enteral nutrition via fistuloclysis demonstrate safety and efficacy, underscoring the importance of tailored nutritional approaches in optimizing patient care for complex surgical conditions.
RESUMO
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.
