Neumatocele en paciente pediátrico. ¿Cuándo debemos actuar? / Pneumatocele in a pediatric patient. When should we act?

El neumatocele es una lesión cavitada llena de aire de carácter adquirido que se encuentra en el interior del parénquima pulmonar. Aunque las causas pueden variar, el origen infeccioso bacteriano es lo más frecuente. Los cambios en los serotipos de neumococo y el aumento de las neumonías necrotizantes observado en las últimas décadas hacen de este tipo de lesiones algo cada vez más frecuente. Es importante conocer la evolución esperable, así como también saber qué paciente se beneficia de intervención para evitar secuelas a largo plazo y complicaciones graves. En este artículo se exponen las causas, epidemiología, orientación diagnóstica y una propuesta de manejo para el neumatocele.

A pneumatocele is an air-filled cavitary lesion of acquired nature located within the pulmonary parenchyma. Although causes can vary, bacterial infectious origin is the most common. Changes in pneumococcal serotypes and the increase in necrotizing pneumonia observed in recent decades have made these lesions increasingly frequent. It is important to know the expected evolution and to identify which patients would benefit from intervention to prevent long-term sequelae and severe complications. This article exposes the causes, epidemiology, diagnostic approach, and a management proposal for pneumatocele.

Introdução: A saúde bucal é um aspecto que não deve ser subestimado pelos pacientes, principalmente se considerar que as infecções odontogênicas podem levar a quadros graves, incluindo complicações cervicotorácicas, como Mediastinite e cervicofaciais, como Angina de Ludwig. Para tanto, é imprescindível que os profissionais da odontologia saibam reconhecer os principais sinais e sintomas dessas infecções, sua evolução, conhecer as complicações associadas e qual o manejo adequado. Objetivo: Assim, é objetivo deste trabalho, relatar, discutir um caso clínico de uma infecção odontogênica grave que acarretou em complicação cervical, com trajeto em direção ao mediastino, necessitando manejo multidisciplinar, e explorar os principais aspectos desse quadro e a conduta necessária, que exige, no mínimo, intervenção cirúrgica, antibioticoterapia e manutenção das vias aéreas. Relato de caso: O caso trata de um paciente com infecção odontogênica, iniciada como uma pericoronarite do dente 38 semieruptado, que evoluiu para a área cervical, demandando imediata drenagem nesta região pois encaminhava-se para uma mediastinite. Após a drenagem cervical e antibioticoterapia e, assim que houve redução do trismo, foi removido o dente 38, evoluindo para a cura.Conclusões:As infecções odontogênicas, principalmente as que acometem os espaços fasciais e cervicais profundos, são potencialmente graves e devem ter suas principais manifestações clínicas entre os domínios de conhecimento dos profissionais Bucomaxilofaciais, pois necessitam de diagnóstico preciso, manejo rápido e tratamento adequado e precoce, considerando a velocidade com que podem evoluir (AU).

Introduction: Oral healthis an aspect that should not be underestimated by patients, especially considering that dental infections can lead to serious symptoms, including cervicothoracic complications, such as Mediastinitis and cervicofacial complications, such as Ludwig's Angina. Therefore, it is essential that dental professionals know how to recognize the main signs and symptoms of these infections, their evolution, know the associated complications and appropriate management.Objective: Thus, this work aims to report and discuss a clinical case of a serious odontogenic infection that resulted in a cervical complication, with a path towards the mediastinum, requiring multidisciplinary management, and to explore the main aspects of this condition and the necessary conduct, which requires, at least, surgical intervention, antibiotic therapy and airway maintenance.Case report: The case concerns a patient with odontogenic infection, which began as pericoronitis of semi-erupted tooth 38, which progressed to the cervical area, requiring immediate drainage in this region as it was heading towards mediastinitis. After cervical drainage and antibiotic therapy and, as soon as the trismus was reduced, tooth 38 was removed, progressing towards healing.Conclusions: Odontogenic infections, especially those that affect the fascial and deep cervical spaces, are potentially serious and should have their main clinical manifestations among the domains of knowledge ofOral and Maxillofacial professionals, as they require accurate diagnosis, rapid management and adequate and early treatment, considering the speed at which they can evolve (AU).

Absceso hepático en Cali, Colombia / Liver abscess in Cali, Colombia

INTRODUCCIÓN: El absceso hepático (AH) es el tipo mas común de abscesos viscerales. Se estima que el perfil epidemiológico de esta enfermedad ha cambiado con el aumento de la resistencia de los microorganismos y el uso de nuevos medicamentos. OBJETIVO: Describir las características demográficas y clínicas de los pacientes hospitalizados con diagnóstico de AH en un hospital universitario del suroccidente colombiano. MÉTODOS: Se realizó un estudio observacional retrospectivo, en la Fundación Valle del Lili, Cali, Colombia. Se incluyeron pacientes mayores de 18 años con diagnóstico de AH hospitalizados entre 2011-2020. RESULTADOS: Se incluyeron 182 pacientes. La mediana de edad fUe 56 años (rango intercuartílico, 45-67) y 62,1% fueron hombres. El microrganismo mas común fue Klebsiella pneumoniae (17,6%). La mayoría requirió drenaje percutáneo (58,2%). El 58,8% tuvo un absceso único y 54,4% fue manejado en cuidados intensivos. El 7,1% de los pacientes falleció. Al comparar los casos que fueron manejados en cuidados intensivos vs. aquellos que no lo fueron, hubo más hepatomegalia (28,3 vs. 11,0%, p = 0,004), derrame pleural derecho (48,5 vs. 28,1%, p = 0,010), cirugía (42,4 vs. 13,4%, p < 0,001), falla terapéutica (22,2 vs. 7,3%, p = 0,007) y muerte (12,1 vs. 1,2%, p = 0,005) en los atendidos en UCI. CONCLUSIÓN: Las Enterobacterales son la principal causa de AH en nuestra población. La mortalidad ha disminuido, pero la hospitalización en cuidados intensivos sigue siendo alta.

BACKGROUND: Liver abscess (LA) is the most common type of visceral abscess. It is estimated that the epidemiological profile of this disease has changed with the increase in resistance and the use of new drugs. AIM: To describe the demographic and clinical characteristics of hospitalized patients with a diagnosis of LA in a university hospital in the southwestern region of Colombia. METHODS: A. retrospective observational study was conducted at Fundación Valle del Lili, Cali, Colombia. Patients older than 18 years with a diagnosis of LA hospitalized between 2011-2020 were included. RESULTS: A total of 182 patients were included. The median age was 56 years (interquartile range, 45-67) and 62.1% were men. The most common microorganism was Klebsiella pneumoniae (17.6%). The majority required percutaneous drainage (58.2%). A 58.8% had a single abscess and 54.4% were treated in ICU. A 7.1% of the patients died. When comparing cases treated in the ICU vs. those who did not, there was more hepatomegaly (28.3 vs. 11.0%, p = 0.004), right pleural effusion (48.5 vs. 28.1%, p = 0.010), surgery (42.4 vs. 13.4%, p < 0.001), therapeutic failure (22.2 vs. 7.3%, p = 0.007) and death (12.1 vs. 1.2%, p = 0.005) in patients treated in ICU. CONCLUSION: Enterobacterales are the main cause of LA in our population. Mortality has decreased, but intensive care hospitalization remains high.

Introducción: la piomiositis (PMS) es una infección bacteriana aguda o subaguda del músculo esquelético. Entidad rara en pediatría, suele acompañarse de la formación de abscesos. Se presenta más frecuentemente en preescolares de sexo masculino, afectando mayoritariamente a extremidades y región pélvica. La manifestación multifocal es frecuente. El principal agente etiológico es Staphylococcus aureus. Caso clínico: 3 años, sexo masculino, sano. Consulta por fiebre continua de hasta 39 ºC de seis días de evolución, dolor de ambos miembros inferiores a predominio izquierdo, cojera y repercusión general. Examen físico: tumoración en muslo izquierdo de límites difusos de 13 x 5 cm, lisa, firme, impresiona adherida a planos musculares, dolorosa. Sin elementos fluxivos en la piel. Ecografía de partes blandas: aumento de tejidos blandos de la extremidad. Resonancia magnética (RM): abscesos que comprometen logia de los aductores del miembro izquierdo, el vasto externo del muslo derecho, musculatura paravertebral lumbar izquierda y cérvico-torácica izquierda. Tratamiento: drenaje, requiere de múltiples limpiezas quirúrgicas y antibioticoterapia prolongada. Cultivo de la lesión: Staphylococcus aureus meticilino resistente (SAMR). Buena evolución clínica e imagenológica. Discusión: la PMS ha presentado una incidencia creciente con la aparición del SAMR. La ecografía es un método adecuado para realizar diagnóstico local. La experiencia en la interpretación de la RM permite pesquisar el compromiso multifocal, identificando focos sin traducción clínica. La antibioticoterapia y el drenaje quirúrgico son los pilares del tratamiento. El pronóstico es bueno en la mayoría de los casos.

Introduction: pyomyositis (PMS) is an acute or subacute bacterial infection of the skeletal muscle. It is a rare infection in pediatrics, and it is usually accompanied by abscess formation. It occurs more frequently in male preschoolers, mostly affecting the extremities and pelvic region. The multifocal manifestation is frequent. The main etiological agent is Staphylococcus aureus. Clinical case: 3 year-old, male, healthy patient. He consulted for continuous fever of up to 39ºC of 6 days of evolution, pain in both lower limbs predominantly on the left, lameness and general repercussions. Physical examination: a 13 x 5 cm tumor in the left thigh with diffuse limits, smooth, firm, adhered to muscle layers, painful. Without fluxive elements on the skin. Soft tissue ultrasound: enlargement of the soft tissues of the extremity. Magnetic resonance imaging (MRI): abscesses involving the adductor lodge of the left limb, the vastus lateralis of the right thigh, left lumbar paravertebral musculature and left cervical-thoracic musculature. Treatment: drainage, requires multiple surgical cleanings and prolonged antibiotic therapy. Culture of the lesion: methicillin-resistant Staphylococcus Aureus (MRSA). Good clinical and imaging evolution. Discussion: PMS has had an increasing incidence with the appearance of MRSA. Ultrasound is a suitable method for local diagnosis. Experience in the interpretation of MRI has enabled us to research multifocal involvement, identifying unobserved foci during clinical check-up. Antibiotic therapy and surgical drainage are the main treatments. The prognosis is good in most cases.

Cavernosografía por TC con reconstrucción 3D: una herramienta urológica para el diagnóstico vascular de la disfunción eréctil de origen venoso / Cavernosografía por TC con reconstrucción 3D: una herramienta urológica para el diagnóstico vascular de la disfunción eréctil de origen venoso

Describir la utilidad de la cavernosografía por tomografía computarizada (TC) de la vasculatura venosa peneana para el diagnóstico de disfunción eréctil de origen venoso. Método: Entre el año 2017 y 2021 en el Servicio de Radiología de la Clínica de la mujer de Bogotá, Colombia, se realizaron 32 cavernosografías como método radiológico para el diagnóstico vascular de pacientes con disfunción eréctil y sospecha de escape venoso. El procedimiento se hizo con un método estandarizado y la lectura de la imagen se hizo utilizando la clasificación del drenaje venoso anómalo mediante TC para la clasificación de escapes venosos: tipo A, sin escape; tipo B, escape sistema venoso profundo; tipo C, escape sistema venoso superficial, y tipo D, escape en sistema venoso superficial y profundo. Resultados: Treinta y dos pacientes fueron diagnosticados con insuficiencia venosaL: tipo A dos pacientes, escape tipo B tres pacientes, escape tipo C cuatro pacientes y escape tipo D 20 pacientes. En dos pacientes poscirugía de ligadura venosa se encontró neovascularización que escapaba y en un paciente con Peyronie se encontró escape venoso superficial y profundo con falta de llenado de los cuerpos cavernosos distales. Conclusión: El diagnóstico etiológico en la disfunción eréctil debe ser un objetivo clínico para poder ofrecer tratamientos exitosos más específicos. Uno de los métodos potenciales de diagnóstico es la realización de cavernosografía por TC en pacientes seleccionados, lo que permite una imagen más detallada anatómicamente profunda del drenaje venoso bajo una visualización tridimensional similar a la que se observaría en una disección quirúrgica.

To describe the usefulness of computed tomography (CT) cavernosography of the penile venous vasculature for the diagnosis of erectile dysfunction of venous origin. Method: Between 2017 and 2021 in the Radiology Service of the Women's Clinic of Bogota, Colombia, 32 cavernosographies were performed as a radiological method for the vascular diagnosis of patients with erectile dysfunction and suspected venous leakage. The procedure was performed with a standardized method and the reading of the image was done using the classification of anomalous venous drainage by CT for the classification of venous leaks: type A, no leak; type B, deep venous system leak; type C, superficial venous system leak, and type D, leak in superficial and deep venous system. Results: Thirty-two patients were diagnosed with venous insufficiency: type A two patients, type B leak three patients, type C leak four patients and type D leak 20 patients. In two patients after venous ligation surgery, neovascularization was found escaping and in one patient with Peyronie's disease, superficial and deep venous leakage was found with lack of filling of the distal cavernous bodies. Conclusion: The etiological diagnosis of erectile dysfunction should be a clinical objective to offer more specific and successful treatments. One of the potential diagnostic methods is the performance of CT cavernosography in selected patients, which allows a more detailed anatomically deep image of the venous drainage under a three-dimensional visualization like what would be seen in a surgical dissection

Escisión de Glándula Submandibular por Sialoadenitis Crónica Esclerosante Asociada a Sialolito en el Conducto Submandibular / Submandibular Gland Excision Due to Chronic Sclerosing Sialadenitis Associated With Sialolith in Submandibular Duct

La sialoadenitis crónica esclerosante puede extenderse desde una sialoadenitis focal hasta una cirrosis completa de la glándula. Aparece entre los 40 y 70 años de edad y afecta principalmente a la glándula submandibular. Se asocia con sialolitos y agentes infecciosos inespecíficos. La causa más frecuente de sialolitiasis es la formación de cálculos macroscópicamente visibles en una glándula salival o en su conducto excretor, de los cuales el 80 % al 90 % provienen de la glándula submandibular. Esta predilección probablemente se deba a que su conducto excretor es más largo, más ancho y tiene un ángulo casi vertical contra la gravedad, contribuyendo así a la estasis salival. Además, la secreción semimucosa de la misma es más viscosa. El sitio principal de ubicación de los litos en el conducto submandibular es la región hiliar con un 57 %. La sintomatología típica de la sialolitiasis es el cólico con tumefacción de la glándula y los dolores posprandiales. Reportamos el caso de un paciente masculino de 55 años, quien ingresa al servicio de Cirugía Oral y Maxilofacial del Hospital General Balbuena de la Ciudad de México por presentar un aumento de volumen en la región submandibular izquierda de consistencia dura y dolorosa a la palpación de 15 días de evolución, acompañada de aumento de temperatura en la zona compatible con un absceso. Los estudios de imagen reportan un sialolito en la región hiliar del conducto submandibular de 2,0 x 1,7 x 1,0 cm. Debido a su localización y tamaño, el tratamiento ideal en estos casos es la escisión de la glándula junto con el lito previo drenaje del absceso e inicio de terapia antibiótica doble.

Chronic sclerosing sialadenitis can range from focal sialadenitis to complete cirrhosis of the gland. It appears between 40 and 70 years of age and mainly affects the submandibular gland. It is associated with sialoliths and nonspecific infectious agents. The most common cause of sialolithiasis is the formation of macroscopically visible stones in a salivary gland or its excretory duct, of which 80 % to 90 % come from the submandibular gland. This predilection isprobably due to the fact that their excretory duct is longer, wider and has an almost vertical angle against gravity, thus contributing to salivary stasis. In addition, the semimucous secretion of it is more viscous. The main location of the stones in the submandibular duct is the hilar region with 57 %. The typical symptomatology of sialolithiasis is colic with swelling of the gland and postprandial pain. We report the case of a 55-year-old male patient, who was admitted to the Oral and Maxillofacial Surgery Service of the Hospital General Balbuena in Mexico City due to an increase in volumen in the left submandibular region that was hard and painful on palpation of 15 days of evolution, accompanied by increased temperature in the area compatible with an abscess. Imaging studies report a 2.0 x 1.7 x 1.0 cm sialolith in the submandibular duct hilar region. Due to its location and size, the ideal treatment in these cases is excision of the gland together with the stone previous drainage of the abscess and initiation of dual antibiotic therapy.

Fístula sigmoido-glútea como complicación infrecuente de la enfermedad diverticular / Sigmoid-gluteal fistula as a rare complication of diverticular disease

Las fistulas colo-cutáneas de origen diverticular son poco frecuentes, máxime en ausencia de cirugía o drenaje percutáneo previos. Presentamos una mujer de 90 años con una sigmoitis complicada con una colección abdominal perforada hacia el retroperitoneo y la región glútea. (AU)

Mama supranumeraria: resección mediante técnica abierta con dren versus sin dren / Supranumerary breast: resection by open technique with drain vs without drain

Introducción. El tejido mamario accesorio es una anomalía congénita que se presenta en el 2-6 % de la población femenina. En este tejido se pueden desarrollar las mismas patologías que en la mama normal. El manejo curativo es la resección quirúrgica. El objetivo de este estudio fue comparar los resultados de la técnica de resección vía abierta de tejido mamario accesorio con dren vs sin dren. Métodos. Se realizó un estudio observacional tipo cohorte retrospectivo, teniendo en cuenta dos grupos de pacientes con tejido mamario accesorio: a uno de ellos se les realizó resección quirúrgica mediante técnica abierta con dren y al otro grupo sin dren. Además, se incluyó un brazo prospectivo donde se evaluó la calidad de vida y la satisfacción de las pacientes con el resultado posoperatorio mediante el uso de la herramienta Breast-Q. Resultados. Se recolectó la información de 82 pacientes, la mayoría mujeres; 22 se intervinieron con técnica con dren y 60 con técnica sin dren. 13,6 % de los pacientes presentaron complicaciones tempranas, siendo la infección de sitio operatorio la más frecuente (36,4 %). En general, las complicaciones fueron más comunes en el grupo con dren (40,9 % vs 3,4 %), con una diferencia estadísticamente significativa (p=0,000). La calidad de vida fue similar en ambos grupos. Conclusiones. Los pacientes a quienes se les realizó resección de mama supernumeraria y se dejó un sistema de drenaje en el lecho de disección presentaron más complicaciones posoperatorias que las pacientes a quienes no se les dejó dren

Introduction. Accessory breast tissue is a congenital anomaly that occurs in 2-6% of the female population. It can develop the same pathologies that in the normal breast. The curative management of this pathology is surgical resection. The objective of this study was to compare the results of the accessory breast tissue open resection technique with a drain vs without a drain. Methods. An observational retrospective cohort study was conducted considering two groups of patients with accessory breast tissue: one of them underwent surgical resection using an open technique with a drain and the other group without a drain. In addition, a prospective arm where the quality of life and satisfaction of the patients with the postoperative result was evaluated by the Breast-Q tool. Results. Eighty-two patients were included, most of them women; 22 were operated with open technique with drain and 60 without drain. 13.6% of patients presented early complications, with surgical site infection being the most frequent (36.4%) and, in general, complications were more common in the group with drain (40.9% vs 3.4%) with a statistically significant difference (p=0.000). Quality of life was similar in both groups.Conclusions. Patients who undergo supernumerary breast resection and leaving drainage in the dissection bed present more postoperative complications compared to those without drain

Abscesos renales: experiencia en un hospital pediátrico de referencia / Renal abscesses: Experience at a referent Pediatric Hospital

INTRODUCCIÓN: El absceso renal es infrecuente en pediatría, con clínica y laboratorio inespecíficos. Ante su sospecha, es necesario realizar imágenes para establecer diagnóstico. Objetivo: Describir las características clínico-epidemiológicas, microbiológicas, diagnósticas y terapéuticas de abscesos renales en pediatría. PACIENTES Y MÉTODOS: Estudio retrospectivo, descriptivo, de pacientes internados con absceso renal, en seguimiento por Infectología del Hospital de Niños Ricardo Gutiérrez, durante 9 años. RESULTADOS: 15 pacientes (67% varones), mediana de edad 9 años (rango [r] 0,7-17). Cuatro pacientes con comorbilidades. El síntoma más frecuente fue fiebre seguido por dolor lumbar. El recuento medio de leucocitos en sangre fue de 15.700/mm3 (r: 7.100-45.000) y la PCR de 193 mg/L (r: 1-362). Cuatro pacientes presentaron urocultivo positivo: dos Escherichia coli, uno Klebsiella pneumoniae y E. coli y otro Candida albicans y K. pneumoniae. Ningún paciente presentó bacteriemia. El diagnóstico se confirmó por ecografía. Se realizó drenaje en siete pacientes, con aislamiento de Staphylococcus aureus en dos y Pseudomonas aeruginosa en uno. El tratamiento incluyó terapia combinada en 67%. Mediana de antibioterapia intravenosa fue 16 días (r: 7-49), total de 28 (r: 14-91). Un paciente requirió terapia intensiva y dos, nefrectomía. CONCLUSIÓN: Los abscesos renales son infrecuentes, con gran morbimortalidad. Sospechar en paciente con infección del tracto urinario (ITU) de evolución tórpida que persiste febril. En nuestro estudio, la alta sensibilidad de la ecografía renal permitió su diagnóstico precoz.

BACKGROUND: Renal abscesses are infrequent in pediatrics, with nonspecific clinical and laboratory findings. When suspected, imaging is essential to establish the diagnosis. Aim: To describe the clinical-epidemiological, microbiological, diagnostic and therapeutic characteristics of renal abscesses in pediatrics. METHODS: Retrospective and descriptive study of hospitalized patients with renal abscess, followed by Infectious Diseases Department of Ricardo Gutiérrez Children's Hospital during 9 years. Statistical analysis: Epi Info 7.2.2.6. RESULTS: 15 patients (67% male), median age 9 years (range [r] 0.7-17) were included. Four patients had underlying disease. The most frequent symptom was fever, with a median duration of 10 days (r:1-36), followed by lumbar pain. The median white blood cell count was 15,700/mm3 (r: 7,100-45,000) and CRP 193mg/L (r: 1-362). Four patients presented positive urine culture: 2 Escherichia coli, 1 Klebsiella pneumoniae and E. coli and 1 Candida albicans and K. pneumoniae. No patient had bacteremia. The diagnosis of abscess was confirmed by ultrasound. Surgical drainage was performed in 7 patients, with isolation of Staphylococcus aureus in 2 and Pseudomonas aeruginosa in 1. Empirical treatment included 3rd generation cephalosporin, combined in 67% of cases. The median of intravenous antibiotic therapy was 16 days (r: 7-49) with a total of 28 days (r:14-91). One patient required transfer to intensive care unit and 2 nephrectomy. CONCLUSION: Renal abscesses are infrecuent in pediatrics, but they present significant morbidity and mortality. It should be suspected in patients with urinary tract infection (UTI)with torpid evolution that persists with fever without antibiotic response. In our study, the high sensitivity of renal ultrasound allowed early diagnosis.

Evolution and progress of surgical intervention strategies for acute pancreatitis / 中华外科杂志

Acute pancreatitis is one of the common surgical acute abdominal diseases. Since people first recognized acute pancreatitis in the middle of the nineteenth century, a diversified minimally invasive treatment model with standardization has been formed today. According to the main line of surgical intervention of acute pancreatitis treatment,this period can be roughly divided into five stages:exploration stage, conservative treatment stage, pancreatectomy stage, debridement and drainage of the pancreatic necrotic tissue stage, and minimally invasive treatment as the first choice led by the multidisciplinary team mode stage. Throughout history, the evolution and progress of surgical intervention strategies for acute pancreatitis cannot be separated from the progress of science and technology, the update of treatment concepts and the further understanding of the pathogenesis. This article will summarize the surgical characteristics of acute pancreatitis treatment at each stage to explain the development of surgical treatment of acute pancreatitis,to help investigate the development of surgical treatment of acute pancreatitis in the future.

Transanal drainage tube for prevention of anastomotic leak after anterior resection for rectal cancer: a meta-analysis / 中华胃肠外科杂志

Objective: To assess the effectiveness of transanal drainage tube (TDT) in reducing the incidence of anastomotic leak following anterior resection in patients with rectal cancer. Methods: We conducted a systematic search for relevant studies published from inception to October 2022 across multiple databases, including PubMed, Embase, Web of Science, Cochrane Library, CNKI, Wanfang, and VIP. Meta-analysis was performed using Review Manager 5.4 software. The primary outcomes included total incidence of anastomotic leak, grade B and C anastomotic leak rates, reoperation rate, anastomotic bleeding rate, and overall complication rate. Results: Three randomized controlled trials involving 1115 patients (559 patients in the TDT group and 556 in the non-TDT group) were included. Meta-analysis showed that the total incidences of anastomotic leak and of grade B anastomotic leak were 5.5% (31/559) and 4.5% (25/559), respectively, in the TDT group and 7.9% (44/556) and 3.8% (21/556), respectively, in the non-TDT group. These differences are not statistically significant (P=0.120, P=0.560, respectively). Compared with the non-TDT group, the TDT group had a lower incidence of grade C anastomotic leak (1.6% [7/559] vs. 4.5% [25/556]) and reoperation rate (0.9% [5/559] vs. 4.3% [24/556]), but a higher incidence of anastomotic bleeding (8.2% [23/279] vs. 3.6% [10/276]). These differences were statistically significant (P=0.003, P=0.001, P=0.030, respectively). The overall complication rate was 26.5%(74/279) in the TDT group and 27.2% (75/276) in the non-TDT group. These differences are not statistically significant (P=0.860). Conclusions: TDT did not significantly reduce the total incidence of anastomotic leak but may have potential clinical benefits in preventing grade C anastomotic leak. Notably, placement of TDT may increase the anastomotic bleeding rate.

Clinical management and prognosis for descending necrotizing mediastinitis / 中华耳鼻咽喉头颈外科杂志

Objective: To investigate the clinical characteristics, treatment experiences and prognostic factors for descending necrotizing mediastinitis (DNM). Methods: A retrospective analysis was performed on the data of 22 patients with DNM diagnosed and treated in Henan Provincial People's Hospital from January 2016 to August 2022, including 16 males and 6 females, aged 29-79 years. After admission, all patients underwent CT scanning of the maxillofacial, cervical, and thoracic regions to confirm their diagnoses. Emergency incision and drainage were performed. The neck incision was treated with continuous vacuum sealing drainage. According to the prognoses, the patients were divided into cure group and death group, and the prognostic factors were analyzed. SPSS 25.0 software was used to analyze the clinical data. Rusults: The main complaints were dysphagia (45.5%, 10/22) and dyspnea (50.0%, 11/22). Odontogenic infection accounted for 45.5% (10/22) and oropharyngeal infection accounted for 54.5% (12/22). There were 16 cases in the cured group and 6 cases in the death group, with a total mortality rate of 27.3%. The mortality rates of DNM typeⅠand typeⅡwere respectively 16.7% and 40%. Compared with the cured group, the death group had higher incidences for diabetes, coronary heart disease and septic shock (all P<0.05). There were statistically significant differences between the cure group and the death group in procalcitonin level (50.43 (137.64) ng/ml vs 2.92 (6.33) ng/ml, M(IQR), Z=3.023, P<0.05) and acute physiology and chronic health evaluation Ⅱ(APACHEⅡ) score (16.10±2.40 vs 6.75±3.19, t=6.524, P<0.05). Conclution: DNM is rare, with high mortality, high incidence of septic shock, and the increased procalcitonin level and APACHE Ⅱ score combined diabetes and coronary heart disease are the poor prognostic factors for DNM. Early incision and drainage combined with continuous vacuum sealing drainage technique is a better way to treat DNM.

OBJECTIVE@#To evaluate the feasibility and safety of one- stage bilateral video-assisted thoracic surgery (VATS) for resection of bilateral multiple pulmonary nodules (BMPNs).@*METHODS@#We analyzed the clinical characteristics, pathological features, perioperative outcomes and follow-up data of 41 patients with BMPNs undergoing one-stage bilateral VATS from July, 2011 to August, 2021.@*RESULTS@#One-stage bilateral VATS was performed uneventfully in 40 of the patients, and conversion to open surgery occurred in 1 case. The surgical approaches included bilateral lobectomy (4.9%), lobar-sublobar resection (36.6%) and sublobar-sublobar resection (58.5%) with a mean operative time of 196.3±54.5 min, a mean blood loss of 224.6±139.5 mL, a mean thoracic drainage duration of 4.7±1.1 days and a mean hospital stay of 14±3.8 days. Pathological examination revealed bilateral primary lung cancer in 15 cases, unilateral primary lung cancer in 21 cases and bilateral benign lesions in 5 cases. A total of 112 pulmonary nodules were resected, including 67 malignant and 45 benign lesions. Postoperative complications included pulmonary infection (5 cases), respiratory failure (2 cases), asthma attack (2 cases), atrial fibrillation (2 cases), and drug-induced liver injury (1 case). No perioperative death occurred in these patients, who had a 1-year survival rate of 97.6%.@*CONCLUSION@#With appropriate preoperative screening and perioperative management, one-stage bilateral VATS is feasible and safe for resection of BMPNs.

The timing of pericardial drainage catheter removal and restart of the anticoagulation in patients suffered from perioperative pericardial tamponade during atrial fibrillation catheter ablation and uninterrupted dabigatran: Experiences from 20 cases / 中华心血管病杂志

Objective: To investigate the timing of pericardial drainage catheter removal and restart of the anticoagulation in patients with atrial fibrillation (AF) suffered from perioperative pericardial tamponade during atrial fibrillation catheter ablation and uninterrupted dabigatran. Methods: A total of 20 patients with pericardial tamponade, who underwent AF catheter ablation with uninterrupted dabigatran in Beijing Anzhen Hospital from January 2019 to August 2021, were included in this retrospective analysis. The clinical characteristics of enrolled patients, information of catheter ablation procedures, pericardial tamponade management, perioperative complications, the timing of pericardial drainage catheter removal and restart of anticoagulation were analyzed. Results: All patients underwent pericardiocentesis and pericardial effusion drainage was successful in all patients. The average drainage volume was (427.8±527.4) ml. Seven cases were treated with idarucizumab, of which 1 patient received surgical repair. The average timing of pericardial drainage catheter removal and restart of anticoagulation in 19 patients without surgical repair was (1.4±0.7) and (0.8±0.4) days, respectively. No new bleeding, embolism and death were reported during hospitalization and within 30 days following hospital discharge. Time of removal of pericardial drainage catheter, restart of anticoagulation and hospital stay were similar between patients treated with idarucizumab or not. Conclusion: It is safe and reasonable to remove pericardial drainage catheter and restart anticoagulation as soon as possible during catheter ablation of atrial fibrillation with uninterrupted dabigatran independent of the idarucizumab use or not in case of confirmed hemostasis.

Analysis of the causes of long-standing pelvic anterior sacral space infection and discussion of management techniques / 中华肿瘤杂志

Objective: To investigate the causes and management of long-term persistent pelvic presacral space infection. Methods: Clinical data of 10 patients with persistent presacral infection admitted to the Cancer Hospital of Zhengzhou University from October 2015 to October 2020 were collected. Different surgical approaches were used to treat the presacral infection according to the patients' initial surgical procedures. Results: Among the 10 patients, there were 2 cases of presacral recurrent infection due to rectal leak after radiotherapy for cervical cancer, 3 cases of presacral recurrent infection due to rectal leak after radiotherapy for rectal cancer Dixons, and 5 cases of presacral recurrent infection of sinus tract after adjuvant radiotherapy for rectal cancer Miles. Of the 5 patients with leaky bowel, 4 had complete resection of the ruptured nonfunctional bowel and complete debridement of the presacral infection using an anterior transverse sacral incision with a large tipped omentum filling the presacral space; 1 had continuous drainage of the anal canal and complete debridement of the presacral infection using an anterior transverse sacral incision. 5 post-Miles patients all had debridement of the presacral infection using an anterior transverse sacral incision combined with an abdominal incision. The nine patients with healed presacral infection recovered from surgery in 26 to 210 days, with a median time of 55 days. Conclusions: Anterior sacral infections in patients with leaky gut are caused by residual bowel secretion of intestinal fluid into the anterior sacral space, and in post-Miles patients by residual anterior sacral foreign bodies. An anterior sacral caudal transverse arc incision combined with an abdominal incision is an effective surgical approach for complete debridement of anterior sacral recalcitrant infections.
