Incidence and related factors of umbilical venous catheter tip migration / 中华围产医学杂志

Objective:To analyze the incidence and the related factors of umbilical vein catheter (UVC) tip migration within 7 d after umbilical vein catheterization.Methods:This prospective study involved neonates who were successfully indwelled with UVCs in the Department of Neonatology of Gansu Provincial Women and Child-care Hospital from June 2020 to December 2021. The position of the UVC tip, length of umbilical stump, body weight, and abdominal circumference were recorded after the UVCs were inserted successfully, and the changes in these four data at 2, 24, 48, 72 h, and 7 d after catheterization were analyzed and compared. All the subjects were divided into the non-migrate group, inward migration group, and outward migration group. Chi-square test, Mann-Whitney U test, or Kruskal Wallis H test were used for statistical analysis. Results:A total of 157 newborns were enrolled, with 51 cases in the inward migration group, 62 cases in the outward migration group, and 44 cases in the non-migrate group. There were no significant differences among the three groups regarding gestational age, birth weight, gender, born through cesarean section, age at the time of catheterization, use of sedation, and feeding modes (all P>0.05). The migration rates of UVCs tip at 2, 24, 48, 72 h, and 7 d after catheterization were 0, 27.4% (43/157), 27.2% (31/114), 25.3% (21/83), and 29.0% (18/62), respectively. The cumulative migration rates at 24, 48, 72 h, and 7 d were 27.4% (43/157), 47.1% (74/157), 60.1% (95/157), and 72.0% (113/157), respectively. Compared with the non-migrate group, the inward migration group had a shorter umbilical cord stump at 24 and 48 h [0.5 cm (0.4-0.5 cm) vs 0.6 cm (0.5-0.8 cm); 0.4 cm (0.3-0.5 cm) vs 0.5 cm (0.5-0.6 cm), Z=－5.55 and －3.69, both P<0.05], less abdominal circumference increment at 48 and 72 h [0.6 cm (0.5-1.0 cm) vs 0.9 cm (0.7-1.2 cm); 0.6 cm (0.3-0.9 cm) vs 0.9 cm (0.7- 1.3 cm), Z=－2.03 and －2.09, both P<0.05)], and more weight loss percentage [－4.7% (－6.0%-－3.6%) vs －3.1% (－3.7%-－2.2%); －6.0% (－7.5%-－5.0%) vs －3.9% (－5.1%-－2.4%), Z=－3.75 and －2.96, both P<0.05]. The abdominal circumference increased more in the outward migration group at 24, 48, 72 h, and 7 d than those in the non-migrate group [1.6 cm (0.9-1.9 cm) vs 0.7 cm (0.5-0.9 cm); 1.5 cm (1.2-1.8 cm) vs 0.9 cm (0.7-1.2 cm); 1.7 cm (1.3-1.9 cm) vs 0.9 cm (0.7-1.3 cm); 1.6 cm (1.1-1.9 cm) vs 0.9 cm (0.6-1.3 cm), Z=－4.82, －4.79, －3.74, and －3.09, all P<0.05]. Conclusion:The incidence of UVC tip migration is high, which could be affected by dryness and retraction of the umbilical cord stump and the change in neonatal abdominal circumference and body weight.

Migración de dispositivo intrauterino a vejiga / Intrauterine device migration to bladder

Introducción: La litiasis vesical secundaria se forma en el reservorio vesical y requiere la existencia de condiciones patológicas previas como lo son los cuerpos extraños. Objetivo: Describir dos casos clínicos de litiasis vesical secundaria a migración de un dispositivo intrauterino. Caso clínico: Se presentan dos casos de migración intravesical de dispositivo intrauterino con litiasis vesical secundaria. Se diagnosticaron años después de su inserción, ante la aparición de dolor pélvico, cistitis a repetición y hematuria. La laparoscopia no fue útil para su diagnóstico. En consulta de Urología la ultrasonografía y la radiografía de pelvis fueron herramientas diagnósticas útiles ante la sospecha inicial de esta patología. Presentaron buena evolución y regresión total de los síntomas tras cistolitotomía suprapúbica. Conclusión: Se debe pensar en la posibilidad de migración de un dispositivo intrauterino a vejiga ante la cronicidad de síntomas urinarios irritativos bajos en toda mujer que emplee este método anticonceptivo y desconozca su paradero(AU)

Introduction: Secondary bladder lithiasis is formed in the bladder reservoir and requires the existence of previous pathological conditions such as foreign bodies. Objective: To describe two clinical cases of bladder lithiasis secondary to intrauterine device migration. Clinical case report: Two cases of intravesical migration of an intrauterine device with secondary bladder stones are reported. They were diagnosed years after insertion, due to the appearance of pelvic pain, recurrent cystitis and hematuria. Laparoscopy was not helpful for its diagnosis. In Urology consultation, ultrasound and pelvic radiography were useful diagnostic tools in the event of the initial suspicion of this pathology. They showed good evolution and total regression of symptoms after suprapubic cystolithotomy. Conclusion: The possibility of an intrauterine device migration to the bladder should be considered when chronicity of irritative low urinary symptoms in every woman who uses this contraceptive method and which locations are unknown(AU)

Laparoscopy treatment of liver abscess secondary to an unusual foreign body (rosemary twig)

A hepatic abscess caused by a swallowed foreign body is a rare and challenging diagnosis. Most patients have nonspecific symptoms, and more than 90% of patients do not remember having swallowed it, which occurred accidentally. In this setting, fish bones, chicken bones, and toothpicks are the most found foreign bodies. We reported the case of a 54-year-old male patient admitted with abdominal pain and intermittent fever. He was diagnosed with liver abscess and treated successfully with antibiotics and a laparoscopic procedure; a rosemary twig was found during the abscess drainage procedure. Furthermore, a literature review of 22 cases of laparoscopic treated liver abscesses associated with a foreign body was made.

Una espina en un pajar: espina de pescado alojada en la tiroides / A fish bone in a haystack: fish bone lodged in thyroid

Introducción. La ingestión accidental de cuerpos extraños como espinas de pescado es muy poco frecuente; en ocasiones, pueden alojarse en el esófago y es posible su migración extraluminal. Este accidente se presenta principalmente en países asiáticos por el gran consumo de pescado. La migración extraluminal de una espina de pescado desde el esófago a la glándula tiroides es aún más infrecuente, con pocos reportes en la literatura.Objetivo. Presentar nuestra experiencia en el diagnóstico y manejo quirúrgico de un paciente con un cuerpo extraño (espina de pescado) alojado en la glándula tiroides y, asimismo, hacer una revisión de la literatura científica.Caso clínico. Se presenta una paciente de 53 años, sin antecedentes de importancia y con un cuadro clínico de tres meses de evolución consistente en odinofagia posterior a la ingestión accidental de una espina de pescado. En la ecografía practicada en otra institución se observó un cuerpo extraño alojado en el lóbulo tiroideo izquierdo en relación con la musculatura del esófago. En la tomografía de cabeza y cuello se apreciaba una imagen hiperdensa lineal de 2,6 cm de longitud en la misma localización. En la exploración quirúrgica se encontró tejido fibrótico en la región posterior del lóbulo tiroideo izquierdo y se procedió a practicar una tiroidectomía subtotal izquierda. La evolución posoperatoria fue adecuada.Conclusiones. La migración extraluminal de cuerpos extraños en el tubo digestivo es factible, sobre todo la de las espinas de pescado por su morfología. La tomografía es la herramienta diagnóstica más confiable para detectar cuerpos extraños alojados en la glándula tiroides. Es necesario conocer las posibles complicaciones y, asimismo, optimizar las posibles intervenciones, pues de eso depende el pronóstico clínico del paciente

Introduction: Accidental ingestion of foreign bodies such as fish bones is very rare; sometimes they may lodge in the esophagus, and extraluminal migration is possible. This accident occurs mainly in Asian countries due to the large fish consumption. Extraluminal migration of a fish bone from the esophagus to the thyroid gland is even more infrequent, with few reports in the literature.Objective: To present our experience in the diagnosis and surgical management of a patient with a foreign body (fish bone) lodged in the thyroid gland and to review the scientific literature.Clinical Case: A 53-year-old patient is presented, without a significant history and with a clinical picture of three months of evolution consisting of odynophagia after accidental ingestion of a fish bone. In the ultrasound performed at another institution, a foreign body was observed lodged in the left thyroid lobe in relation to the musculature of the esophagus. Head and neck tomography showed a linear 2.6 cm long hyperdense image at the same location. On surgical exploration, fibrotic tissue was found in the posterior region of the left thyroid lobe and a left subtotal thyroidectomy was performed. Postoperative evolution was adequate.Conclusions: Extraluminal migration of foreign bodies in the digestive tract is feasible, especially that of fish bones due to their morphology. Tomography is the most reliable diagnostic tool to detect foreign bodies lodged in the thyroid gland. It is necessary to know the possible complications and to optimize the possible interventions, since the clinical prognosis of the patient depends on it

External Iliac Artery Laceration Caused by Hip Prosthesis Migration / Laceração da artéria ilíaca externa por migração de prótese da anca

Abstract Hip arthroplasty is a common and safe intervention in orthopedic surgery. However, the proximity of this joint to large vessels makes the occurrence of vascular injury a rare but serious and possibly lethal complication of this surgical technique. Acute vascular injuries in the context of a hip arthroplasty have variable etiologies and clinical presentations, and are more common in revision surgeries and in situations of medial intrapelvic migration and of chronic infection of the hip prosthesis. In the present article, the authors present a case of acute and late major vascular complication in the context of hip arthroplasty revision. The patient developed an acute laceration of the external iliac artery caused by chronic and progressive medial intrapelvic acetabular migration of the hip prosthesis associated with chronic infection.

Resumo A artroplastia da anca é uma intervenção frequente e segura na cirurgia ortopédica. No entanto, a proximidade dessa articulação com vasos de grande calibre faz com que a ocorrência de lesão vascular maior seja uma complicação rara, mas grave e possivelmente letal, dessa técnica cirúrgica. As lesões vasculares agudas no contexto de uma artroplastia da anca têm etiologia e apresentação clínica variáveis e são mais frequentes em cirurgias de revisão e situações de migração medial intrapélvica e de infecção crônica de próteses da anca. No presente artigo, os autores apresentam um caso com complicação vascular maior aguda e tardia em contexto de revisão de prótese da anca. Trata-se de um paciente que desenvolveu uma laceração aguda da artéria ilíaca externa em contexto de migração acetabular intrapélvica crônica progressiva da prótese da anca associada a infecção crônica.

Migración intracraneal de aceite de silicona a través del nervio óptico post-vitrectomía / Intracranial migration of silicone oil through the optic nerve post-vitrectomy

La migración intracraneal del aceite de silicona intraocular es una complicación rara en el tratamiento de las complicaciones de la retinopatía diabética. Se han postulado varios posibles mecanismos etiopatogénicos para explicar este fenómeno de migración. El aceite de silicona se presenta hiperdenso en la tomografía, siendo un desafío distinguirlo de la hemorragia subaracnoidea, resaltando la utilidad de la resonancia magnética. En pacientes con evidencia de retinopexia de silicona previa, la visualización de una lesión intraventricular con un artefacto de desplazamiento químico asociado aumenta la posibilidad de que se trate de una migración del aceite de silicona. Presentamos el caso de un paciente con antecedente de retinopexia con aceite de silicona y cefalea intensa, identificándose migración del aceite de silicona al sistema ventricular con estudios de tomografía y resonancia.

The intracranial migration of intraocular silicone oil is a rare complication in the treatment of complications of diabetic retinopathy. Several possible etiopathogenic mechanisms have been published to explain this phenomenon of migration. Silicone oil appears hyperdense on tomography, being a challenge to distinguish it from subarachnoid hemorrhage, highlighting the usefulness of magnetic resonance imaging. In patients with evidence of previous silicone retinopexy, the visualization of an intraventricular lesion with a chemical displacement device presents the possibility that it is a migration of the silicone oil. To present the case of a patient with a history of retinopexy with silicone oil and intense headache, identifying the migration of silicone oil in the ventricular system with tomography and resonance studies.

Kirschner Wire Migration after the Treatment of Acromioclavicular Luxation for the Contralateral Shoulder - Case Report / Migração do fio de Kirschner após o tratamento da luxação acromioclavicular para o ombro contralateral - relato de caso

Abstract The use of metal wires, called Kirschner wires, is a simple and effective fixation method for the correction of shoulder fractures and of dislocations in orthopedic surgery.Wire migration during the postoperative follow-up is a possible complication of the procedure. The authors present the case of a 48-year-old male patient, a business administrator, who suffered a fall from his own height during a soccer match resulting in right shoulder trauma. The patient was treated at a specialized orthopedics and trauma hospital and was diagnosed with a grade V acromioclavicular dislocation. Four days after the trauma, the acromioclavicular dislocation was surgically treated using ligatures with anchor wires, coracoacromial ligament transfer, and fixation with Kirshner wires from the acromion to the clavicle. At the follow-up, 12 days after the surgical procedure, migration of the Kirschner wire to the acromion edge was identified. The patient was oriented to undergo another surgery to remove the Kirshner wire, due to the possibility of further migration; nonetheless, he refused the surgery. Nine months after the surgical treatment, the patient complained of pain on the left shoulder (contralateral side), difficulty tomobilize the shoulder, ecchymosis, and protrusion. Bilateral radiographs demonstrated that the Kirschner wire, originally from the right shoulder, was on the left side. The patient then underwent a successful surgery to remove the implant.

Resumo O uso dos fios metálicos, denominados fios de Kirschner, é um método de fixação simples e eficaz para a correção de fraturas e luxações do ombro na cirurgia ortopédica. Uma das possíveis complicações é a migração do fio durante o acompanhamento pósoperatório. Os autores apresentam um caso de um paciente masculino de 48 anos, administrador, que sofreu uma queda de mesmo nível com trauma em ombro direito durante uma partida de futebol. Atendido emumhospital de referência de ortopedia e traumatologia, foi diagnosticada luxação acromioclavicular grau V. Quatro dias após o trauma, fez-se o tratamento cirúrgico da luxação acromioclavicular com amarrilhos com fios de âncora, transferência do ligamento coracoacromial e fixação com fio de Kirchner do acrômio à clavícula. No retorno, 12 dias após o procedimento cirúrgico, identificou-se amigração do fio de Kirschner do bordo do acrômio. Apesar de orientado a se submeter a cirurgia para remoção do fio, o paciente se recusou.Novemeses após o tratamento cirúrgico, o paciente apresentou dores no ombro esquerdo (lado contralateral), dificuldade para mobilizar o ombro, equimose e saliência. Foram feitas radiografias bilaterais e foi constatado que o fio de Kirschner, originalmente no ombro direito, estava no ombro contralateral. Fez-se então cirurgia para remoção do implante, com sucesso.

Sawing Through The Neck - A Case of Serrated Fish Bone Migrating to Prevertebral Space

@#Fish bone is the commonest pharyngeal foreign body, however migrating fish bone is a rare occurrence. We report a case of a 54-year-old male who had history of fish bone ingestion over a week and presented with odynophagia and worsening neck pain. Rigid esophagoscopy revealed tip of a fish bone which was embedded in granulation tissue. The fish bone migrated further with manipulation. Aided with computed tomography scan findings, the serrated fish bone was finally removed via transcervical approach without any complication. In conclusion, high index of suspicion and prompt removal of migrating fish bone with the aid of computed tomography imaging is necessary to avoid fatal complications.

Abdominal Pain Due to Hem-o-lok Clip Migration after Laparoscopic Cholecystectomy / 대한소화기학회지

During laparoscopic cholecystectomy, a surgical clip is used to control the cystic duct and cystic artery. In the past, metallic clips were usually used, but over recent years, interest in the use of Hem-o-lok clips has increased. Surgical clip migration into the common bile duct (CBD) after laparoscopic cholecystectomy has rarely been reported and the majority of reported cases involved metallic clips. In this report, we describe the case of a 53-year-old woman who presented with abdominal pain caused by migration of a Hem-o-lok clip into the CBD. The patient had undergone laparoscopic cholecystectomy 10 months previously. Abdominal CT revealed an indistinct, minute, radiation-impermeable object in the distal CBD. The object was successfully removed by sphincterotomy via ERCP using a stone basket and was identified as a Hem-o-lok clip.

Silent invasion of Hem-O-Lok clip

A 58-year-old man underwent laparoscopy-assisted distal gastrectomy (LADG) with Billroth I gastroduodenostomy due to early gastric cancer. During surgery, the perigastric vessels were ligated with Hem-o-Lok clips. Esophagogastroduodenoscopy (EGD) 6 months later showed a fungating mass at the anastomosis site. Repeat EGD 1 year after LADG showed a Hem-o-Lok clip at the fungating mass lesion. Because the patient was asymptomatic, with no major abnormalities on clinical examination, and endoscopic removal of the clip would have been difficult due to the presence of adhesions and inflammation, no attempt was made to remove the clip. The patient remained well after the exposed Hem-o-Lok clip was identified. A third EGD 6 months later showed that the clip had disappeared from the anastomosis site, and that this site was covered with normal mucosa surrounding the scar.

Embolization by Bullet Dislodged from the Heart

Abstract Embolization by a dislodged projectile is a rare complication that may occur in cases of gunshot cardiac injuries. We report a case of a firearm projectile cardiac injury that evolved, with dislocation of the projectile during cardiac surgery, into embolization of the right external carotid artery.

Bezoar gástrico de plástico como causa de pancreatitis aguda: reporte de un caso y revisión de la literatura / Gastric plastic bezoar causing acute pancreatitis: case report and literature review

Introducción. Un bezoar se define como un elemento no digerible atrapado en algún punto del tubo digestivo, el cual puede ser ingerido de forma intencional o accidental. El primer reporte de un bezoar en la literatura médica lo hizo Baudamant en 1779. Caso clínico. Se presenta un caso de un bezoar de plástico, un cepillo dental, como causa de pancreatitis aguda y su manejo por laparoscopia, con una revisión de la literatura. Discusión y conclusiones. Aunque los bezoares gástricos son poco frecuentes, y más aún el de plástico, es importante tenerlos en cuenta como causa de pancreatitis aguda. Definitivamente, el abordaje laparoscópico es el ideal en pacientes sin obstrucción intestinal o inestabilidad hemodinámica

Introduction: A bezoar is defined as an indigestible element trapped somewhere in the gastrointestinal tract, which can be ingested intentionally or accidentally. The first report of a Bezoar in the medical literature was by W. Baudamant in 1779. Case report: We present the case of a plastic bezoar, a toothbrush, as the cause of acute pancreatitis and its management by laparoscopy, and a literature review. Discussion and conclusions: Although gastric bezoars are rare conditions, and furthermore so plastic bezoars, it is important to take them into account as a rare cause of acute pancreatitis. Definitely the laparoscopic approach is ideal for patients without intestinal obstruction or hemodynamic instability

Migration of a contraceptive subdermal device into the lung

A single-rod subdermal contraceptive implant is usually located around the insertion site, has been usually known to migrate within less than 2 cm of the insertion site and the true migration over 2 cm has been rarely reported. We report a case of migrated radiopaque subdermal contraceptive implant into lung in a 37-year-old woman. On conducted chest computed tomography, subdermal contraceptive implant was in subsegmental branch in left posterior basal segment of lung. Removal of subdermal contraceptive implant in left posterior basal segment of lung by mini-thoracotomy was performed by a chest surgeon. Complications with insertion and removal of subdermal contraceptive implant are rare in the hands of medical professionals familiar with the techniques and these procedures should only be undertaken by those with relevant training. The migration over 2 cm should not occur if the correct subdermal insertion procedure is followed and carried out by a properly trained individual.

Late Migration of Amplatzer Septal Occluder Device to the Descending Thoracic Aorta

Percutaneous closure of atrial septal defect (ASD) has become an increasingly common procedure. Serious complications of the procedure, such as cardiac migration, are rare, and usually occur <72 hours after device placement. In this report, we present the case of a patient who underwent successful surgical treatment for the migration of an ASD occluder device to the thoracic aorta 12 months after ASD closure.

Polymethyl methacrylate (Linnea Safe) causes local inflammatory response after intramuscular implant in BALB/c mice but it is not observed in distant organs / Polimetilmetacrilato (Linnea Safe) provoca resposta inflamatória localizada após implante intramuscular em camundongos BALB/c, mas não é observado em órgãos a distância

ABSTRACT Introduction: Among its different therapeutic functions, the use of polymethyl methacrylate (PMMA) for more than a decade has has stood out in the replacement of the volumes lost with the aging process and filling in wrinkles and creases. It is considered a permanent biomaterial despite its reliability is widely discussed by health professionals. Objective: To analyze the size of the microspheres in of three different commercialized types of PMMA, and the inflammatory process generated by the implant, as well as to evaluate possible migration of the microspheres. Methods: The polymers of the brands Biossimetric®, MetaCrill® and Linnea Safe® were analyzed by scanning electron microscope (SEM) and had the dispersion and the size of its particles determined. After this analysis, it was decided to implant in BALB/c mice the polymer of the brand Linnea Safe®, which was the more homogeneous product. The animals submitted to polymer implantation were euthanized at 3, 7, 15, 30, 60, 90 and 120 days after implantation, allowing the weighing of the implanted paws and the histopathological analysis of some tissues. Results: It was observed that the implantation of Linnea Safe® PMMA microspheres in mice triggered an acute inflammatory process 3 to 15 days after the surgical procedure, evolving to chronic non-granulomatous inflammation with collagen deposition, tissue reorganization after 30 days of PMMA implantation up to 120 days; also, no microspheres were observed in distant organs. Conclusion: The Linnea Safe® PMMA behaved as a safe and stable biomaterial, once its microspheres were sized to prevents phagocytosis, and leads to local and controlled inflammation.

RESUMO Introdução: Entre suas diversas funções terapêuticas, há mais de uma década o polimetilmetacrilato (PMMA) vem se destacando na reposição de volumes perdidos com processo de envelhecimento e preenchimento de sulcos e rugas. É considerado um biomaterial permanente, apesar de sua confiabilidade ser amplamente discutida por profissinais da área da saúde. Objetivos: Analisar o tamanho das microesferas de três formas comercializadas de PMMA e o processo inflamatório gerado pelo implante, bem como avaliar a possível migração das microesferas. Métodos: Os polímeros das marcas Biossimetric®, MetaCrill® e Linnea Safe® foram analisados por microscópio eletrônico de varredura (MEV) e tiveram a dispersão e o tamanho de suas partículas determinados. Após essa análise, decidiu-se implantar em camundongos BALB/c o polímero da marca Linnea Safe®, o qual se apresentou mais homogêneo. Os animais submetidos ao implante do polímero foram eutanasiados aos 3, 7, 15, 30, 60, 90 e 120 dias após o implante, permitindo a realização da pesagem das patas implantadas e a análise histopatológica de alguns tecidos. Resultados: Observou-se que a implantação de microesferas de PMMA Linnea Safe® em camundongos desencadeou um processo inflamatório agudo de 3 a 15 dias após o procedimento cirúrgico, evoluindo para inflamação crônica não granulomatosa com deposição de colágeno e reorganização do tecido após 30 dias de implantação de PMMA até 120 dias; além disso, não foram observadas microesferas em órgãos a distância. Conclusão: O PMMA da marca Linnea Safe® comportou-se como um biomaterial seguro e estável, uma vez que as microesferas apresentaram tamanho que impedem sua fagocitose e provocam inflamação localizada e controlada.

Appendicitis caused by ingestion of metal foreign body / Apendicite provocada por ingesta de corpos estranhos metálicos

INTRODUCTION: The ingestion of foreign bodies is a frequent occurrence, especially among children. The majority of these objects travel safely through the gastrointestinal tract, without causing symptoms or leaving sequelae. Acute appendicitis is the emergency surgical pathology of greater prevalence. However, the impaction of a foreign body into the appendicular lumen as an etiologic agent of appendicitis is a very rare event. CASE REPORT: We describe the case of a 21-year-old male patient with lower abdominal pain over approximately six days, in association with vomiting, fever and abdominal distension. After imaging studies, a radiopaque foreign body was identified in a pelvic topography, with distention and air-fluid levels in intestinal loops. Our patient was submitted to an open appendectomy, evidencing acute perforated appendicitis and the presence of two foreign bodies in its lumen. The patient progressed satisfactorily in the post-operative period, with use of broad-spectrum antibiotics. DISCUSSION: Foreign bodies impacted in the gastrointestinal tract are usually removed by endoscopic techniques. When these bodies cause infections, there should be a resolution, preferably by surgical laparoscopy, which will serve both for diagnostic as therapeutic purposes. (AU)

INTRODUÇÃO: A ingesta de corpos estranhos é um acontecimento frequente, principalmente entre crianças. A maioria destes passa de forma inócua pelo trato gastrointestinal, sem causar sintomas ou deixar sequelas. Apendicite aguda é a patologia cirúrgica emergencial de maior prevalência. CONTUDO: a impactação de um corpo estranho no lúmen apendicular como agente etiológico de apendicite é um evento muito raro. RELATO DE CASO: Descrevemos o caso de um paciente masculino de 21 anos com quadro de dor abdominal baixa há aproximadamente 6 dias, associando-se a vômitos, febre e distensão abdominal. Após exames de imagem, identificou-se corpo estranho radiopaco em topografia pélvica, distensão e níveis hidroaéreos em alças intestinais. Foi submetido a apendicectomia laparotômica, evidenciando-se apendicite aguda perfurada e presença de dois corpos estranhos em seu lúmen. Evoluiu de forma satisfatória no pós-operatório, tendo-se feito uso de antibióticos de largo espectro. DISCUSSÃO: Corpos estranhos impactados no trato gastrointestinal são usualmente retirados por técnicas endoscópicas. Quando provocam quadros infecciosos, deve-se proceder a uma resolução cirúrgica, preferencialmente por videolaparoscopia, a qual servirá tanto para fins diagnósticos quanto terapêuticos. (AU)

Migrated pharyngeal fish bone causing spondylodiscitis. Case report / Espondilodiscite causada por espinha de peixe migrada para faringe. Relato de caso / Espondilodiscitis causada por espina de pescado migrada para la faringe. Relato de caso

Ingestion of foreign bodies is a common problem seen at emergency rooms and frequently involves chicken and fish bones. There are few cases of migrated foreign bodies through the retropharynx causing infectious process in the area but no one, despite the proximity, causing spondylodiscitis. Perhaps such condition is attributed to the integrity of the longus colli fascia covering and protecting the cervical spine. We described the first case of spondylodiscitis due to a foreign body (saw-toothed fish bone) that penetrated the longus colli fascia and carved into vertebral body C3.

A ingestão de corpos estranhos é problema comum nos pronto-socorros e geralmente ocorrem com ossos de aves e espinhas de peixes. Há alguns relatos de casos de migração de corpos estranhos para a retrofaringe, que causam processo infeccioso local, mas não há nenhum caso descrito de espondilodiscite (apesar da proximidade). Talvez a ausência de infecção na coluna vertebral decorra da integridade da fáscia do músculo longo do pescoço, que recobre e protege a coluna cervical. Descrevemos o primeiro caso de espondilodiscite em decorrência de migração de uma espinha serrilhada de peixe que penetrou profundamente na fáscia do músculo longo do pescoço e atingiu o corpo vertebral de C3.

La ingestión de cuerpos extraños es un problema común en los puestos de primeros auxilios y, generalmente, ocurre con huesos de aves y espinas de pescados. Hay algunos relatos de casos de migraciones de cuerpos extraños para la retrofaringe, las cuales causan procesos infecciosos locales, pero no hay ningún caso descrito de espondilodiscitis (aun considerando la proximidad). Quizás la ausencia de infección en la columna vertebral resulte de la integridad de la fascia del músculo largo del cuello, que recubre y protege a la columna cervical. Describimos el primer caso de espondilodiscitis causado por la migración de una espina serrada de pescado, la cual penetró profundamente en la fascia del músculo largo del cuello y alcanzó al cuerpo vertebral de C3.

Misplacement or Migration? Extremely Rare Case of Cardiac Migration of a Ureteral J Stent

A 29-year-old woman with mild back pain when coughing and suprapubic discomfort after voiding was admitted to Pusan National University Hospital. Two weeks earlier, she had undergone a hysterectomy and right-sided ureteroneocystostomy for uterine atony and right ureteral injury with bladder rupture. Computed tomography showed that a ureteral J stent extended from the right ovarian vein to the right cardiac chamber. The stent was retrieved via both femoral veins with a snare loop and pigtail catheter. Computed tomography showed that the urinary and vascular tracts were normal 5 months after the procedure.

Absceso hepático piógeno por hueso de pescado: reporte de un caso / Pyogenic liver abscess due to fish bone: case report

Se informa el caso de un hombre residente en la ciudad de Bogotá, Colombia, quien consultó al servicio de urgencias del Hospital el Tunal de dicha ciudad por dolor abdominal progresivo de seis días de evolución, localizado en el cuadrante superior derecho, asociado a ictericia y fiebre, sin antecedentes relevantes. Al ingreso tenía deterioro marcado del estado general, por lo que requirió atención en la unidad de cuidados intesivos; se le hicieron estudios de imágenes diagnósticas que documentaron una colección multiseptada en el lóbulo hepático izquierdo, y un cuerpo extraño. En la laparotomía se encontró un hueso de pescado como causa del absceso. Con el drenaje y la terapia antibiótica la evolución fue favorable.

We report the case of a man who consulted the emergency department of Hospital el Tunal in Bogotá, Colombia, because of six days of progressive abdominal pain in the upper right quadrant, associated with jaundice and fever; there was no relevant information in his medical history. On admission he was found in poor general condition and required management in the intensive care unit; diagnostic imaging studies documented a multiseptate collection in the left hepatic lobe, and a foreign body. He was submitted to laparotomy in which a fish bone was found as the cause of the abscess. After drainage of the collection and with antibiotic therapy evolution was favorable.
