Complicaciones perianales causadas por agentes modeladores inyectados en glúteos / Perianal complications caused by gluteal injection of modeling agents

En este reporte presentamos tres pacientes en quienes ocurrieron condiciones inflamatorias perianales tardías, luego de la administración de sustancias modeladoras no identificadas en los glúteos. El diagnóstico inicial y supuesto no fue correcto, ya que no se investigó durante la evaluación preliminar el antecedente de la administración de elementos modeladores. Recomendamos que los pacientes con patologías inflamatorias del ano, sobre todo aquellos cuyo curso es extraño, se les pregunte acerca de la administración de agentes modeladores en los glúteos. Esta práctica puede contribuir a la eficacia del diagnóstico de manifestaciones perianales caracterizadas por flogosis, que se presentan de forma inusual. (AU)

In this report we present three patients in which late perianal inflammatory conditions occurred after administration of unidentified modeling agents to the buttocks. The initial diagnosis was not correct because of the administration of modeling agents was not investigated during the initial eval-uation. We recommend inquiring patients with inflammatory pathologies of the anus, especially those whose course is unusual, about the adminis-tration of modeling agents to the buttocks. This approach can contribute to the efficiency of the diagnosis of perianal complaints characterized by inflammation, but rare in its appearance. (AU)

Migração para veia hepática de cateter totalmente implantável para quimioterapia em paciente com carcinoma de mama: relato de caso / Hepatic vein migration of a totally implantable venous access port-a-cath for chemotherapy in a breast carcinoma patient: case report

Resumo O cateter totalmente implantável (CTI) é utilizado na administração da quimioterapia. Em menos de 1% dos casos de complicação, pode ocorrer migração do CTI para quimioterapia para a circulação sistêmica. O objetivo deste estudo foi descrever um caso de migração do CTI para a veia hepática. Uma paciente do sexo feminino, de 44 anos de idade, teve diagnóstico de câncer de mama com indicação de quimioterapia neoadjuvante. Realizou-se a implantação de cateter port-a-cath. Durante o procedimento de punção do cateter, houve retorno normal de sangue, e foi realizada infusão de soro fisiológico. Em seguida, houve um aumento de volume no local do port e não retorno de sangue à aspiração. A radiografia de tórax mostrou embolização do cateter em topografia hepática. Retirou-se o cateter pela técnica do laço (sem complicações), e a paciente recebeu alta no dia seguinte. Possíveis alterações no funcionamento do CTI devem chamar atenção da equipe responsável.

Abstract A totally implantable venous access port (TIVAP) is used for chemotherapy administration. Venous port migration to the systemic circulation occurs in less than 1% of complications. The aim of this study is to describe a case of TIVAP migration to the hepatic vein. A 44-year-old female patient with breast cancer was prescribed neoadjuvant chemotherapy. A port-a-cath was surgically implanted for chemotherapy. During the port puncture procedure, blood returned normally when aspirated. When the port was first accessed and flushed with saline solution, swelling was observed at the port site and blood could no longer be aspirated. A chest radiography showed catheter embolization in the region of the hepatic vein. The catheter was retrieved using a snare technique (without complications) and the patient was discharged the next day. The care team should be alert to possible TIIVAP malfunction.

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.

Espina de pescado alojada en la glándula tiroides / Fishbone lodged in the thyroid gland

Los cuerpos extraños alojados en la vía aéreodigestiva superior son un motivo de consulta frecuente para el otorrinolaringólogo. Uno de los más frecuentes son las espinas de pescado. En raras ocasiones, éstas migran hacia tejidos adyacentes y generan complicaciones importantes. Presentamos el caso de una paciente que tras la ingesta de pescado manifiesta sensación de cuerpo extraño faríngeo, odinofagia y dolor látero cervical derecho. Dada la ausencia de hallazgos a la exploración física y laringoscópica se realiza una tomografia computarizada cervical, visualizando un cuerpo extraño alojado en la glándula tiroidea. Se interviene mediante cervicotomía media, realizando la extracción de la espina sin complicaciones. El diagnóstico precoz y manejo adecuado es determinante para prevenir complicaciones en estos casos.

Foreign bodies in the aerodigestive tract are commonly confronted in otolaryngology practice. The most frequent are the fish bones. In rare cases they can move and cause numerous complications. We report the case of a patient that manifest the sensation of pharyngeal foreign body, after fish ingestion. She also referred odynophagia and right cervical pain. Physical and laryngoscopic examination were normal. A cervical CT was performed, where a foreign body lodged in the thyroid gland was visualized, median cervicotomy was done and the foreign body was extracted. Early diagnosis and adequate management are crucial to prevent complications in these cases.

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

Hiatal hernia repair: prevention of mesh erosion and migration into the esophagogastric junction / Correção de hérnia hiatal: prevenção de erosão e migração de tela na junção esofagogástrica

ABSTRACT Background: Erosion and migration into the esophagogastric lumen after laparoscopic hiatal hernia repair with mesh placement has been published. Aim: To present surgical maneuvers that seek to diminish the risk of this complication. Method: We suggest mobilizing the hernia sac from the mediastinum and taking it down to the abdominal position with its blood supply intact in order to rotate it behind and around the abdominal esophagus. The purpose is to cover the on-lay mesh placed in "U" fashion to reinforce the crus suture. Results: We have performed laparoscopic hiatal hernia repair in 173 patients (total group). Early postoperative complications were observed in 35 patients (27.1%) and one patient died (0.7%) due to a massive lung thromboembolism. One hundred twenty-nine patients were followed-up for a mean of 41+28months. Mesh placement was performed in 79 of these patients. The remnant sac was rotated behind the esophagus in order to cover the mesh surface. In this group, late complications were observed in five patients (2.9%). We have not observed mesh erosion or migration to the esophagogastric lumen. Conclusion: The proposed technique should be useful for preventing erosion and migration into the esophagus.

RESUMO Racional: Com a colocação de tela foi têm sido publicadas erosões e migrações para o lúmen esofagogástrico após correção de hérnia hiatal laparoscópica. Objetivo: Apresentar manobras cirúrgicas que buscam diminuir o risco dessa complicação. Método: Sugerimos mobilizar o saco de hérnia do mediastino e levá-lo à posição abdominal com o suprimento sanguíneo intacto, a fim de girá-lo para trás e ao redor do esôfago abdominal. O objetivo é cobrir a malha colocada sobre a forma "U" para reforçar a sutura da crura haital. Resultados: Realizamos reparo laparoscópico de hérnia hiatal em 173 pacientes (grupo total). Complicações pós-operatórias precoces foram observadas em 35 pacientes (27,1%) e um morreu (0,7%) devido a tromboembolismo pulmonar maciço. Cento e vinte e nove pacientes foram acompanhados por média de 41+28 meses. A colocação da tela foi realizada em 79 desses pacientes. O saco remanescente foi girado atrás do esôfago para cobrir a superfície da tela. Nesse grupo, complicações tardias foram observadas em cinco pacientes (2,9%). Não observamos erosão da tela ou migração dela para o lúmen esofagogástrico. Conclusão: A técnica proposta pode ser útil para prevenir a erosão e a migração para o esôfago de telas na correção de hérnias hiatais.

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.

Incidence of thrombotic events and complications associated to inferior vena cava filters in patients with and without anticoagulation therapy / Incidencia de eventos trombóticos y complicaciones asociadas al uso de filtros de vena cava en pacientes en pacientes con o sin terapia anticoagulante

Abstract Objective: Anticoagulation is the primary management to prevent venous thromboembolism; inferior vena cava filters (IVCFs) provide a mechanical prophylactic alternative when anticoagulation is contraindicated. The aim of this study was to evaluate in IVCF patients, whether the initiation of anticoagulation therapy is associated with decreased rates of recurrent thrombotic events and device-related complications. Methods: This was a retrospective review of patients that underwent insertion of IVCF. Subjects with IVCF were studied in two groups: those initiated on anticoagulation (A) and without anticoagulation (NA). Variables as indications for IVCF, anticoagulation, recurrence of thrombosis, complications, and reinterventions were examined. Results: From April 2007 to March 2014, 54 patients underwent IVCF placement; (61% of females), with mean age of 54 years (standard deviation ± 19). 28 (52%) were initiated on anticoagulation, during a mean follow-up period of 28 months, five experienced recurrent thrombosis and three were on the A group (p=0.5); when comparing patients that developed post-thrombotic syndrome, seven were in the A group and seven in the NA. Two patients with IVC rupture were in the A group (p=0.5), and the only case of IVCF migration occurred in the A group. 11 (20%) patients died from comorbidities nonrelated to the device or procedure (four in the A cohort). Conclusions: Patients with IVCF on anticoagulation have equivalent rates of thrombotic events and device-related complications than those patients NA.

Resumen Objetivo: La anticoagulación es la terapia de elección para la prevención de tromboembolismo venoso; los filtros de vena cava inferior (FVCI) proveen una alternativa mecánica profiláctica cuando la anticoagulación está contraindicada. El objetivo de este estudio fue evaluar si la terapia anticoagulante se asocia con una tasa menor de eventos trombóticos recurrentes y complicaciones relacionadas con el dispositivo. Métodos: Los pacientes fueron categorizados en dos grupos: Aquellos a los que se les inicio anticoagulación (A) y aquellos que no (NA). Variables tales como indicación de la colocación del filtro, anticoagulación, recurrencia de trombosis y complicaciones fueron examinadas. Resultados: De abril de 2007 a marzo 2014, a 54 pacientes se les coloco un filtro (61% fueron mujeres), con una media de edad de 54 años [Desviación estándar (DE) ±19. Veintiocho (52%) fueron iniciados en anticoagulación y durante un seguimiento de 28 meses, 5 pacientes experimentaron recurrencia de trombosis, 3 en el grupo A (p=0.5). Al comparar los pacientes que desarrollaron síndrome posflebítico, 7 pertenecieron al grupo A y 7 al grupo NA. Dos pacientes con ruptura de vena cava pertenecieron al grupo A (p=0.5) y el único caso de migración del dispositivo ocurrió en el grupo A. Once (20%) pacientes fallecieron debido a comorbilidades no relacionadas con el dispositivo o el procedimiento. Conclusión: Pacientes con FVCI en anticoagulación tienen tasas de eventos trombóticos y complicaciones asociadas a los dispositivos equivalentes a aquellos pacientes sin anticoagulación.

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.

Removal of intramural trapped intrauterine device by cystoscopic incision of bladder wall

ABSTRACT A healthy 37 - year - old woman referred to our clinic with one - year history of recurrent urinary tract infection, dysuria and frequency. Her past medical history informed us that an IUD (Copper TCu380A) had been inserted 11 years ago. Eleven months after the IUD insertion she had become pregnant, unexpectedly. At that time, she had undergone gynecological examination and abdominal ultrasound study. However, the IUD had not been found, and the gynecologist had made the diagnosis of spontaneous fall out of the IUD. She had experienced normal pregnancy and caesarian section with no complications. On physical examination, pelvic examination was normal and no other abnormalities were noted. Urinalysis revealed microhematuria and pyuria. Urine culture was positive for Escherichia coli. Ultrasound study revealed a calculus of about 10 mm in the bladder with a hyperdense lesion. A plain abdominal radiograph was requested which showed a metallic foreign body in the pelvis. We failed to remove the IUD by cystoscopic forceps because it had strongly invaded into the uterine and bladder wall. Despite previous papers suggesting open or laparoscopic surgeries in this situation (1, 2), we performed a modified cystoscopic extraction technique. We made a superficial cut in the bladder mucosa and muscle with J - hook monopolar electrocautery and extracted it completely with gentle traction. This technique can decrease the indication of open or laparoscopic surgery for extraction of intravesical IUDs. In the other side of the coin, this technique may increase the risk of uterovesical fistula. Therefore, the depth of incision is important and the surgeon should cut the bladder wall superficially with caution. Although present study is a case report which is normally classified as with low level of evidence, it seems that our modified cystoscopic extraction technique is a safe and useful method for extraction of partially intravesical IUDs.

Colocación de Endobutton intraarticular posterior a plástica de ligamento cruzado anterior / Intra-articular migration of Endobutton fixation following ACL reconstruction

La ruptura del ligamento cruzado anterior es una patología frecuente en deportistas, siendo la reconstrucción del mismo uno de los procedimientos más frecuentes en la cirugía ortopédica. Se han descripto múltiples técnicas quirúrgicas, con distintos injertos y sistemas de fijación. Si bien la fijación femoral es controvertida, el sistema de fijación suspensoria con Endobutton demostró tener una fuerza biomecánica mayor que la de los tornillos interferenciales. La migración intraarticular del Endobutton es una complicación infrecuente que ha sido descripta previamente en la literatura. Presentamos el caso de un paciente masculino de 24 años de edad, con una migración intraarticular del Endobutton posterior a una plástica del ligamento cruzado anterior de cuatro meses de evolución

The anterior cruciate ligament (LCA) ruptures are a frequent pathology in athletes, being the reconstruction one of the most frequent procedures in orthopedic surgery. Many surgical techniques have been described, with different grafts and fixation systems. Although femoral fixation is controversial, the suspensory fixation system with Endobutton have demonstrated a greater biomechanical force in comparison with interferential screws. The intra-articular migration of Endobutton is an infrequent complication that has been previously described in the literature. We present a 24 years male patient, with an intraarticular migration of the Endobutton posterior LCA reconstruction of four months of evolution. Two stage revision ACL reconstruction were performed modifying the fixation method to a bone patellar bone graft

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.

¿Que se trago mi hijo? Urgencias en niños por ingestión de cuerpo extraño. Experiencia de seis años en un hospital pediátrico / What did my son drink? Emergency in children due to ingestion of foreign body. Six-year experience in a pediatric hospital

La ingestión de cuerpo extraño (CE) es la segunda causa de endoscopia de urgencia después de la hemorragia de vías digestivas; es un problema frecuente en la población pediátrica. Los niños pueden ingerir cualquier tipo de objeto, la mayoría de los cuales pueden pasar sin inconvenientes por el tracto gastrointestinal. No obstante, algunos pueden poner en riesgo la vida o acarrear complicaciones

Foreign body ingestion is the second cause of emergency endoscopy after bleeding from the digestive tract; It is a frequent problem in the pediatric population. Children can ingest any type of object, most of which can pass without inconvenience through the gastrointestinal tract; however, some can be life-threatening or complicating
