Effect of stainless-steel wire internal fixation on intracapsular condylar fracture.

OBJECTIVES: The aim of the study was to investigate the clinical effect of stainless-steel wire fixation on the early mouth-opening movement of an intracapsular fracture involving the condylar process. MATERIALS AND METHODS: In this study, patients who underwent mandibular condylar intracapsular fracture surgery in our hospital from 2012 to 2020 were selected as research subjects. A total of 44 patients received steel wire internal fixation treatment, 32 patients received titanium plate-and-nail rigid internal fixation, and 28 patients underwent conservative non-surgical treatment. RESULTS: For the patients in the stainless-steel wire group, the degree of mouth opening reached normal levels of 3.7 cm approximately 10 days after surgery. The recovery time for the patients in the titanium plate-and-nail rigid internal-fixation group was 21 days, while the patients in the conservative treatment group needed 60 days to recover. CONCLUSION: The treatment of fixation with a stainless-steel wire for intracapsular condylar fracture reduced the time taken to perform mouth-opening exercises and improved the recovery rate of patients.

Morphological aspects and pathological impacts of cystic echinococcosis in liver of slaughtered sheep and host-parasite relationship / [Aspectos morfológicos e impactos patológicos da equinococose cística no fígado de ovelhas abatidas e relação hospedeiro-parasita]

ABSTRACT Cystic echinococcosis (CE) is a parasite-borne disease caused by the larval stage of Echinococcus granulosus belonging to family Taeniidae, is an endemic disease, distributed worldwide as a neglected parasite with socioeconomic repercussions. It causes severe alterations in liver of infected host, and it could be fatal if untreated. The main objective of the present study is to measure and evaluate the condition of hydatidosis in slaughtered sheep in Al Baha region, Saudi Arabia. A total of 601 slaughtered sheep in Al Baha abattoirs were examined for hydatidosis during the year 2020. Various organs were examined for the presence of parasite cysts, and the cyst contents were examined by light microscopy. Also, liver sections infected with cysts were examined for pathological alterations and host-parasite interactions. Forty-two animals were infected (6.09%) with the highest prevalence during summer. During gross examination, it was observed that the sheep liver is the most affected organ by the disease. The liver contained multiple cysts with varying sizes, filled with clear to slightly turbid fluid containing protoscoleces. Detailed sections of the infected liver revealed significant fibrosis around the central vein, portal vein congestion, infiltration of inflammatory cells, and necrosis. Sections through hydatid cysts showed the presence of three surrounding layers with a laminar membrane bordering the cyst lined by a germinal epithelium surrounding several brood capsules with many protoscolesces inside supported by a set of rostellar hooklets. Considerable efforts should be spent to control the transmission of parasitic cysts and inhibit the incorrect disposal of infected meat from slaughterhouses. Also, more focus should be done on epidemiological and control programs of these parasites.

RESUMO A equinococose cística (EC) é uma doença transmitida por parasitas causada pelo estágio larval do Echinococcus granulosus, pertencente à família Taeniidae, é uma doença endêmica, distribuída mundialmente como um parasita negligenciado com repercussões socioeconômicas. Ela causa alterações graves no fígado do hospedeiro infectado e pode ser fatal se não for tratada. O principal objetivo do presente estudo é medir e avaliar a condição da hidatidose em ovelhas abatidas na região de Al Baha, na Arábia Saudita. Um total de 601 ovelhas abatidas em matadouros de Al Baha foram examinadas quanto à hidatidose durante o ano de 2020. Vários órgãos foram examinados quanto à presença de cistos de parasitas, e o conteúdo dos cistos foi examinado por microscopia de luz. Além disso, seções de fígado infectadas com cistos foram examinadas quanto a alterações patológicas e interações hospedeiro-parasita. Quarenta e dois animais foram infectados (6,09%), com a maior prevalência durante o verão. Durante o exame macroscópico, observou-se que o fígado das ovelhas é o órgão mais afetado pela doença. O fígado continha vários cistos de tamanhos variados, preenchidos com fluido claro a levemente turvo contendo protocistos. Seções detalhadas do fígado infectado revelaram fibrose significativa ao redor da veia central, congestão da veia porta, infiltração de células inflamatórias e necrose. As seções através dos cistos hidáticos mostraram a presença de três camadas circundantes, com uma membrana laminar que margeia o cisto, revestida por um epitélio germinativo que envolve várias cápsulas de cria com muitos protoscolescentes em seu interior, sustentados por um conjunto de ganchos rostelares. Esforços consideráveis devem ser despendidos para controlar a transmissão de cistos parasitários e inibir o descarte incorreto de carne infectada em abatedouros. Além disso, deve-se dar mais atenção aos programas epidemiológicos e de controle desses parasitas.

Uso de injertos capsulares autólogos periprotésicos en mamoplastías estéticas / Used of peri prosthetics autologous capsular graft in aesthetic mammoplasty

INTRODUCCIÓN Y OBJETIVO: presentamos nuestra experiencia con el uso de injertos de capsulas autólogas peri protésicas en pacientes que evolucionaron con ptósis mamaria importante, que tenían implantes siliconados envejecidos implantados en plano subglandular y que además presentaban contractura capsular unilateral Baker III o IV y donde fue necesario cambiar de plano de implantación a sub muscular prolongando la cobertura protésica de musculo pectoral con capsulas autólogas a manera de injer-to simple para cubrir totalmente al implante siliconado, obtenidas de la mama sana contra lateral tipo I a II de Baker, seguido de la mamoplastia de elevación. El objetivo del trabajo es utilizar y reaprovechar tejidos autólogos sanos a cero costos. MATERIAL Y MÉTODO: registramos 12 pacientes operadas, de quienes se obtuvo un segmento de capsulas peri protési-cas autólogas resecadas en bloque de la mama sana contra lateral incluyendo el implante en su interior a través de disección digital simple o con electrobisturí, de prótesis implantadas en plano sub glandular. No se reglo el tamaño de la capsula en únicos moldes, sino se utilizó el tamaño requerido para la cobertura del implante, las cuales fueron injertadas uniendo el segmento medial y el distal del músculo pectoral, cubriendo y protegiendo el nuevo implante que fue implantado en plano submuscular. Posteriormente se ejecutó la mamoplastia de elevación. RESULTADOS: de las 12 pacientes, 1 evoluciono con shock anafiláctico por automedicación de una quinolona fluorada y presento edema generalizado, seroma moderado al 5to día de post operación lo que generó una revisión quirúrgica de urgencia, observando necrosis del injerto capsular motivo por el que fueron movidas. Y una paciente presento un aumento significativo y proyección del polo inferior mayor de la mama en relación con su homóloga seguramente porque se injerto un segmento mayor tamaño de capsula y no quedo a tensión suficiente en esa región, pero no se presentó ninguna reacción local inflamatoria excepto una forma asimétrica de esa mama. El resto es decir las otras 10 pacientes evolucionaron satisfactoriamente. CONCLUSIÓN: el uso de capsulas peri protésicas autólogas, son una alternativa técnica para tener en cuenta en mamoplastias de elevación cuando se opta por cambio de plano de implantación de las prótesis, cuando no se cuentan con matrices acelulares de alto costo, siendo un tejido con alta probabilidad de integración a cero costos y cuando es necesario cubrir al implante.

INTRODUCTION AND OBJECTIVE: we present our experience of using periprosthetic autologous capsule grafts in patients who evolved with significant breast ptosis, had aged silicone implants placed in the sub glandular plane, had unilateral capsular contracture Baker III or IV and had the need to change the plane of implantation to sub muscle plane to prolong the prosthetic coverage with autologous grafted capsules obtained from the healthy contralateral breast Baker type I to II, followed by lifting mammoplasty. The objective of this project is to use and take advantage of healthy autologous tissues at no cost. MATERIALS AND METHODS: we registered 12 operated patients from whom we resected, from the healthy contralateral breast, segments of autologous periprosthetic capsules, including the implant inside through simple digital dissection or with an electro scalpel of the prostheses located in the sub-glandular plane. The size of the capsule was not regulated in single mold, instead the required size to cover the implant was used and was grafted joining the medial and distal segment of the pectoral muscle, wrapping and protecting the new implant located at the submuscular plane. Subsequently, mammoplasty elevation was performed. RESULTS: of the 12 patients, 1 evolved, on the 5th day of surgery, with an anaphylactic shock due to self medication with a fluorinated quinolone tablet presenting a generalized edema, intense seroma, leading to an emergency surgical review and observing necrosis on the capsular graft, which had to be removed. Another patient presented a significant increase and projection of the lower pole of the breast in relation to its counterpart, surely because a larger segment of the capsule was grafted and was not tensioned enough in that region. No local inflammatory reaction was observed except for an asymmetric shape of that breast. The ten remaining patients evolved satisfactorily. CONCLUSIONS: the use of autologous periprosthetic capsules is an alternative technique to be considered for mammoplasty elevation when deciding to change the prostheses implantation plane, since it is a tissue with a high probability of integration at no cost, especially when high cost acellular matrices are not available and when it is necessary to cover the new implant.

Treatment of Irreparable Rotator Cuff Tears: Superior Capsular Reconstruction with Fascia Lata Allograft / Tratamento das rupturas irreparáveis do manguito rotador: Reconstrução capsular superior com aloenxerto de fáscia lata

Abstract Objective The objective of the present study was to evaluate the efficacy and safety of superior capsular reconstruction (SCR) using fascia lata allograft. Methods A prospective case series of 15 patients with irreparable supraspinatus tear who underwent SCR using fascia lata allograft. The American Shoulder and Elbow Surgeons (ASES) scale at 12 months after surgery was the primary outcome. The University of California Los Angeles (UCLA), Constant-Murley, and Single Assessment Numeric Evaluation (SANE) scales, in addition to the range of motion, were secondary outcomes. Radiological parameters were also evaluated by simple radiographs and magnetic resonance imaging (MRI). Results Fifteen patients completed 12 months of postoperative follow-up. The ASES score increased from 34.0 to 73.0 (p= 0.005). The UCLA, Constant-Murley, and SANE scales also showed statistically significant differences (p= 0.001; p= 0.005; and p= 0.046). In the evaluation of range of motion, there was improvement in elevation and in external rotation (95 to 140°, p= 0.003; 30 to 60°, p= 0.007). Six patients (40%) had complete graft healing. The clinical outcomes were significantly higher in the patients who presented graft healing. Conclusions Superior capsular reconstruction using a fascia lata allograft is a safe and effective procedure in short follow-up. Level of Evidence IV; Therapeutic Study; Case Series.

Na avaliação da amplitude de movimento, houve melhora na elevação e rotação externa (95 a 140°, p= 0,003; 30 a 60°, p= 0,007). Seis pacientes (40%) tiveram cicatrização completa do enxerto. Os desfechos clínicos foram significativamente maiores nos pacientes que apresentaram cicatrização do enxerto. Conclusões A RCS com aloenxerto de fáscia lata é um procedimento seguro e eficaz com um curto acompanhamento de tempo. Nível de evidência IV; Estudo Terapêutico; Série de casos.

Vasculitis intestinal y hallazgos en la videocápsula endoscópica: reporte de caso y revisión de la literatura / Intestinal Vasculitis and Endoscopic Video Capsule Findings: Case Report and Literature Review

Resumen Las vasculitis sistémicas pueden llegar a afectar los vasos sanguíneos de todos los tamaños, provocando necrosis e inflamación. La granulomatosis con poliangitis (GPA) es una vasculitis de vasos pequeños y medianos. Las presentaciones clínicas pueden ser locales o difusas en el tracto gastrointestinal. Presentamos el caso de un paciente con diagnóstico de vasculitis sistémica asociada a anticuerpos anticitoplasma (ANCA) mieloperoxidasa (MPO) (poliangitis microscópica) confirmada con biopsia renal, con clínica de 15 días consistente en astenia, adinamia, oliguria subjetiva, edema de miembros superiores e inferiores, hiporexia y melenas. En el examen físico, el tacto rectal fue positivo para melenas, posteriormente presentó anemización secundaria a melenas, por lo que se realizó videocápsula endoscópica en la que se evidenciaron hallazgos compatibles con vasculitis entérica. Durante su estancia presentó compromiso multisistémico dado por la afectación renal, pulmonar, neurológica y gastrointestinal, manejada en la unidad de cuidados intensivos (UCI), donde se iniciaron pulsos de esteroide sistémico y hemodiálisis. Conclusión: la vasculitis gastrointestinal es una complicación rara; sin embargo, ocurre y causa una grave amenaza para la vida de los pacientes. El diagnóstico diferencial debe cubrir otras enfermedades inflamatorias, especialmente la enfermedad de Crohn. Su adecuado reconocimiento influencia de forma significativa el pronóstico, pues el inicio rápido de la terapia con esteroides puede cambiar el curso de la enfermedad.

Abstract Systemic vasculitis can affect blood vessels of all sizes, causing necrosis and inflammation. Granulomatosis with polyangiitis (GPA) is a vasculitis of small and medium blood vessels. Clinical manifestations may be local or diffuse in the gastrointestinal tract. We present a patient's case with systemic vasculitis associated with anti-cytoplasmic antibodies (ANCA), myeloperoxidase (MPO) antibodies (microscopic polyangiitis) confirmed through renal biopsy, presenting a 15-day clinical picture consisting of asthenia, adynamia, subjective oliguria, edema of the upper and lower limbs, hyporexia, and melena. The digital rectal examination was positive for melena in the physical examination, later presenting melena with secondary anemization. An endoscopic video capsule was performed, showing findings compatible with enteric vasculitis. During his stay, he presented multisystemic involvement due to renal, pulmonary, neurological, and gastrointestinal involvement, managed in the intensive care unit (ICU), where systemic steroid pulses and hemodialysis started. Conclusion: although gastrointestinal vasculitis is a rare complication, it occurs and threats patients' lives. Differential diagnosis should cover other inflammatory diseases, especially Crohn's disease. Gastrointestinal vasculitis early diagnosis significantly influences prognosis, as prompt steroid therapy can change the course of the disease.

Experience in the Use of Video Capsule Endoscopy in Patients with Unexplained Iron Deficiency Anemia / Experiencia con el uso de la videocápsula endoscópica en pacientes con anemia ferropénica inexplicada

Abstract Introduction: The prevalence of iron deficiency anemia in developed countries has been estimated between 2-5 %, associated with high morbidity and mortality. Etiological identification is sometimes difficult and requires diagnostic methods, such as video capsule endoscopy (VCE). Aim: This study intends to characterize the findings of this technique in patients with unexplained iron deficiency anemia. Materials and methods: Descriptive observational retrospective study. We describe the VCE findings (PillCamSB2-SB3) in all patients seen between 2011 and 2019. The findings were interpreted according to the Saurin classification: normal (P0), uncertain potential (P1), and high bleeding potential (P2). Results: Of the 490 VCEs performed during the study period, 155 indicated iron deficiency anemia; 106 were women (68.4 %), and the mean age was 57.1 ± 16.6 years. The main comorbidities were cardiovascular in 23 (18.3 %) and arterial hypertension in 16 (12.6 %). Antiplatelets were present in 18 (15.4 %) and anticoagulants in six (5.1 %). Small bowel lesions were vascular in 44 studies (28.4 %), inflammatory in 33 (21.2 %), and neoplastic in seven (4.5 %). Angiectasias were the most frequent lesions in 33 cases (21.3 %). P2 lesions were present in 53 VCEs (34.2 %). Conclusions: VCE is helpful in the study of iron deficiency anemia and helps detect positive findings in the midgut in three out of four patients for which it is indicated. The most frequent significant P2 lesions were vascular. These findings allow providing adequate treatment.

Resumen Introducción: la prevalencia de la anemia ferropénica en países desarrollados se ha estimado entre 2 %-5 %, asociada con una alta morbimortalidad.

Objetivo: el objeto del presente estudio fue caracterizar los hallazgos de esta técnica en pacientes con anemia ferropénica inexplicada. Materiales y métodos: estudio descriptivo, observacional y retrospectivo. Se describen los hallazgos de VCE (PillCamSB2-SB3) en todos los pacientes atendidos entre 2011 y 2019. Los hallazgos se interpretaron según la clasificación de Saurin: normal (P0), potencial incierto (P1) y alto potencial de sangrado (P2). Resultados: del total de 490 VCE realizadas durante el período del estudio, 155 se efectuaron con indicación de anemia ferropénica; 106 fueron mujeres (68,4 %) y la edad media fue de 57,1 ± 16,6 años. Las comorbilidades principales fueron cardiovasculares en 23 (18,3 %) e hipertensión arterial en 16 (12,6 %). La ingesta de antiplaquetarios se presentó en 18 (15,4 %) y anticoagulantes en 6 (5,1 %). Las lesiones en el intestino delgado fueron vasculares en 44 estudios (28,4 %), inflamatorias en 33 (21,2 %) y neoplásicas en 7 (4,5 %). Las angiectasias fueron las lesiones más frecuentes en 33 casos (21,3 %). En 53 VCE se presentaron lesiones P2 (34,2 %). Conclusiones: la VCE es útil en el estudio de la anemia ferropénica, y ayuda a detectar hallazgos positivos en el intestino medio en 3 de cada 4 pacientes en los cuales se indica su uso. Las lesiones P2 significativas más frecuentes fueron las vasculares. Estos hallazgos permiten enfocar un tratamiento adecuado.

Utility of capsule endoscopy in the diagnosis of gastrointestinal graft-versus-host disease.

INTRODUCTION AND AIM: Graft-versus-host disease (GvHD) is a complication of hematopoietic cell transplantation, and the small bowel is one of the main targets in the gastrointestinal tract. Capsule endoscopy is a safe procedure and can be useful in the diagnosis of GvHD. The aim of the present study was to compare the diagnostic yield of capsule endoscopy with the histopathologic findings in GvHD. MATERIALS AND METHODS: A retrospective diagnostic test study included all the patients with suspected GvHD that underwent gastroscopy and colonoscopy, with histopathologic evaluation of the biopsies taken, and capsule endoscopy, within the time frame of July 2015 and July 2019. Capsule endoscopy findings were compared with the histopathologic diagnosis, considered the gold standard. RESULTS: Twenty-one patients with GvHD (7 [33%] women; 37 ± 11.9 years of age) were included, 20 (95%) of whom had acute GvHD. The median gastric transit time of the capsule was 55 minutes (20-113) and the median small bowel transit time was 261 minutes (238-434). The entire small bowel was visualized through capsule endoscopy in 17 cases (80.95%). The histopathologic findings and capsule endoscopy findings resulted in the diagnosis of GvHD in 17 and 16 cases, respectively. There was agreement between the histopathologic and capsule endoscopy findings in 18 cases (15 positive and 3 negative). Sensitivity, specificity, positive predictive value, negative predictive value, and diagnostic yield of capsule endoscopy were 88%, 75%, 94%, 60%, and 85%, respectively. CONCLUSIONS: Capsule endoscopy is a safe tool for the diagnosis of GvHD, with high sensitivity and positive predictive value, as well as moderate agreement with histopathologic findings.

Abordaje interhemisférico contralateral. Nota técnica / Contralateral interhemispheric approach. Technical note

El abordaje interhemisférico contralateral es una variante del abordaje interhemisférico transcalloso que permite optimizar el acceso a lesiones ubicadas en los ventrículos laterales o en sus paredes. La planificación del ángulo de entrada mediante neuronavegador nos permitió el manejo de un Cavernoma ubicado sobre el núcleo caudado e inmediato a la cápsula interna sin realizar callosotomía convencional ni comprometer las estructuras sensibles adyacentes.

Contralateral interhemispheric approach is a variant of the well-know interhemispheric transcallosal approach that allows to optimize the lateral wall ventricle lesions management. Neuronavigation planning allowed us to deal with a caudate nucleus cavernoma contiguous to internal capsule without conventional callosotomy and additional damage neither.

Morphologic and molecular study on the lens anterior capsule in systemic sclerosis / Relato sobre estudo morfológico e molecular da cápsula anterior do cristalino na esclerose sistêmica

ABSTRACT This study aimed to analyze the anterior lens capsule specimens from both eyes of a patient with systemic sclerosis and compare them to the eyes of a control patient. No significant differences between systemic sclerosis and control eyes were observed in the results from the hematoxylin-eosin and picrosirius staining. In the samples obtained from both systemic sclerosis and control eyes, there were expressions of caspase, a molecule expressed in cell death by apoptosis. Heparanase was overexpressed in the systemic sclerosis sample compared to the control sample. Therefore, the anterior lens capsule of the patient with systemic sclerosis is probably affected by the disease since it showed marked expression of heparanase 1.(AU)

RESUMO Analisamos as amostras das cápsulas anteriores do cristalino de uma paciente com esclerose sistêmica e comparamos com as de um paciente controle. Não foram observadas diferenças significativas entre esclerose sistêmica e controle nos resultados da coloração com hematoxilina-eosina e picrosirius. Nas amostras obtidas da esclerose sistêmica e do controle, obtivemos expressão de caspase, uma molécula expressa na morte celular por apoptose. A heparinase foi expressa de forma mais marcante na amostra de esclerose sistêmica quando comparada ao controle. Portanto, a cápsula anterior do cristalino da paciente com esclerose sistêmica provavelmente foi afetada pela doença, uma vez que mostrou expressão aumentada de heparinase 1.(AU)

Eficacia de la infiltración periarticular con anestésico local y adyuvantes para control del dolor postquirúrgico en la artroplastía total de rodilla / Effectiveness of peri-articular infiltration with local anesthetic and adjuvants for post-surgical pain control in total knee replacement

Resumen: Introducción: La artroplastía total de rodilla (ATR) es uno de los tratamientos ortopédicos más exitosos; sin embargo, se ha asociado a dolor postquirúrgico intenso en 30-60% de los pacientes. Nosotros planteamos que la infiltración de la cápsula articular de la rodilla durante la cirugía disminuirá el dolor postquirúrgico. Material y métodos: Estudio experimental, aleatorio, doble ciego, en pacientes sometidos a ATR unilateral entre Abril de 2018 a Enero de 2019. Los pacientes fueron divididos en dos grupos, el primero infiltración con placebo y el segundo con solución anestésica y adyuvantes (fentanilo, epinefrina y ketorolaco). Se cuantificó mediante escala visual análoga (EVA) del dolor a las cuatro, seis, ocho, 12, 18, 24, 36 y 48 horas postquirúrgicas, así como del consumo de analgésicos opioides y antieméticos. Resultados: Veinte pacientes en cada grupo, con un seguimiento de cuatro semanas. No hubo diferencias significativas en las características demográficas entre ambos grupos. Se observó un mejor control del dolor postquirúrgico en el grupo que recibió infiltración con anestésico y adyuvante, además de una disminución en el consumo de analgésicos opioides y antieméticos. No hubo diferencia en sangrado ni en la incidencia de infecciones entre ambos grupos. Conclusión: La infiltración pericapsular es un método seguro y eficaz, como parte de la analgesia multimodal en la artroplastía total de rodilla, ya que disminuye el dolor postquirúrgico, el consumo de opioides y antieméticos y no incrementa el sangrado postquirúrgico.

Abstract: Introduction: Total knee arthroplasty (TKA) is one of the most successful orthopedic treatments, however, it has been associated with severe postsurgical pain in 30-60% of patients. We propose that infiltration of the articular capsule of the knee during surgery will decrease postsurgical pain. Material and methods: Experimental, randomized, double-blind study in patients undergoing unilateral TKA between April 2018 and January 2019. Patients were divided into two groups, the first infiltration with placebo and the second with anesthetic solution and adjuvants (fentanyl, epinephrine and ketorolac). Pain was measured with the visual analog scale (VAS) at 4, 6, 8, 12, 18, 24, 36 and 48 hours postsurgical, as well as the consumption of opioid analgesics and antiemetics. Results: 20 patients in each group, with a follow-up of 4 weeks. There were no significant differences in demographic characteristics between the two groups. Better control of postsurgical pain was observed in the group that received infiltration with anesthetic and adjuvant, as well as a decrease in the consumption of opioid analgesics and antiemetics. There was no difference in bleeding or in the incidence of infections between the two groups. Conclusion: Peri-capsular infiltration is a safe and effective method, as part of multimodal analgesia in total knee arthroplasty, as it decreases postsurgical pain, opioid and antiemetic use and does not increase postsurgical bleeding.

Ileal neuroendocrine tumor: diagnosis by endoscopic capsule / Tumor neuroendocrino ileal: diagnóstico por cápsula endoscópica

The diagnosis of neuroendocrine tumors of the small intestine is usually challenging. They are infrequent, and the clinical course is insidious with nonspecific manifestations. Routine endoscopic and abdominal imaging studies are more often unremarkable. Therefore, distant metastases are frequently detected at the time of diagnosis. The tumor markers chromogranin A, synaptophysin, and neuron-specific enolase, and capsule endoscopy, and device-assisted enteroscopy are useful resources to establish a diagnosis. The aim was to present a case of neuroendocrine tumor of small intestine diagnosed with base in findings of the capsule endoscopy and further open surgery.

El diagnóstico de tumores neuroendocrinos del intestino delgado suele ser un desafío. Son infrecuentes y el curso clínico es insidioso con manifestaciones inespecíficas. Los estudios de imágenes endoscópicos y abdominales de rutina suelen ser anodinos. Por tanto, las metástasis a distancia se detectancon frecuencia en el momento del diagnóstico. Los marcadores tumorales cromogranina A, sinaptofi-sina y enolasa neuronal específica, y la cápsula endoscópica y la enteroscopía asistida por dispositivo son recursos útiles para establecer un diagnóstico. El objetivo de este trabajo fue presentar un caso de tumor neuroendocrino de intestino delgado diagnosticado con base en hallazgos de la cápsula endoscópica y de una nueva cirugía abierta.

Diagnóstico de divertículo de Meckel mediante cápsula endoscópica / Diagnose of Meckel's diverticulum through endoscopic capsule

Meckel's diverticulum can be present in up to 1.2% of the population. It is usually diagnosed as an imaging finding, but it can present with complications such as digestive bleeding, intestinal obstruction, diverticulitis, ulcers, and perforation, more frequently in childhood or infancy. The diagnosis workup for this condition will depend on their clinical manifestation, the most frequent being gastrointestinal bleeding of obscure origin or small intestinal bleeding. In this context, although capsule endoscopy is the preferred technique, its diagnostic yield for the detection of Meckel's diverticulum is not entirely clear and it has not been compared in a controlled studies with other diagnostic methods. Here we report the diagnosis of a Meckel diverticulum and its intestinal complications by means of capsule endoscopy in a patient with iron deficiency anemia and gastrointestinal bleeding

El divertículo de Meckel puede estar presente en el 1,2% de la población general. Usualmente es diagnosticado como un hallazgo, pero puede presentarse con mayor frecuencia en la niñez o infancia por sus complicaciones como hemorragia digestiva, obstrucción intestinal, diverticulitis, úlceras y perforación. El enfrentamiento diagnóstico de esta condición dependerá de la manifestación clínica, siendo lo más frecuente hemorragia digestiva de origen oscuro o de intestino delgado. En este contexto, si bien la cápsula endoscópica es la técnica de elección, su rendimiento diagnóstico para la detección del divertículo de Meckel no es del todo claro y no ha sido comparado de forma controlada con otras técnicas diagnósticas. En el presente caso se reporta el diagnóstico de un divertículo de Meckel y sus complicaciones intestinales mediante cápsula endoscópica en una paciente con anemia ferropriva y hemorragia digestiva.

Retención de videocápsula endoscópica, una nueva enfermedad médico-quirúrgica: serie de casos.

BACKGROUND: The endoscopic video capsule (EVC), a minimally invasive method of study of the gastrointestinal system indicated in occult gastrointestinal bleeding, has as main complication the retention of endoscopic capsule (CR), currently it is managed with direct extraction using double-balloon enteroscopy; however, when it fails due to its location or associated pathologies, the surgical intervention results in the most successful approach. OBJECTIVE: To evaluate clinical characteristics and management of patients with video capsule endoscopy retention. METHOD: From January 2001 to December 2018, a retrospective search was carried out in three centers, of patients with CR diagnosis, clinical variables and approach were evaluated, in addition to a critical review of the literature. RESULTS: 15 patients with a diagnosis of CR (eight 8 women and seven men), average age 65 (range: 45-77). Seven required surgical management, three endoscopic and five medical management. CONCLUSIONS: The CR is a new pathology of low prevalence, the surgical management resulting from a second therapeutic line when the removal of the VCE has not been possible endoscopically, this pathology requires special attention in the patient's medical history and symptoms for diagnosis and management.

ANTECEDENTES: La videocápsula endoscópica (VCE), método mínimamente invasivo de estudio del sistema gastrointestinal indicado en hemorragia digestiva oculta, tiene como principal complicación la retención de la cápsula endoscópica (RCE). Actualmente se maneja con extracción directa empleando enteroscopia de doble balón; sin embargo, cuando falla por su localización o por patologías asociadas, la intervención quirúrgica resulta el método de mayor éxito. OBJETIVO: Evaluar las características clínicas y el manejo de pacientes con RCE. MÉTODO: De enero de 2001 a diciembre de 2018 se realizó un búsqueda retrospectiva, en tres centros, de pacientes con diagnóstico de RCE. Se evaluaron variables clínicas y de manejo, y además se realizó una revisión crítica de la literatura. RESULTADOS: Se hallaron 15 pacientes con diagnóstico de RCE (ocho mujeres y siete hombres), con una edad promedio de 65 años (rango: 45-77). Siete requirieron manejo quirúrgico, tres manejo endoscópico y cinco manejo médico. CONCLUSIONES: La RCE es una patología nueva de baja prevalencia. El manejo quirúrgico resulta ser una segunda línea terapéutica cuando la extracción de la VCE no ha sido posible endoscópicamente. Para su diagnóstico y manejo, esta patología requiere una especial atención a la historia clínica, los antecedentes y los síntomas de los pacientes.
