Cuerpos extraños en esófago: revisión de 84 casos

La presencia de cuerpo extraño esofágico (CEE) es una urgencia habitual en gastroenterología. El protocolo en el manejo y la intervención endoscópica puede ser variable entre las instituciones. Objetivo: Definir características clínicas del CEE en adultos, su diagnóstico radiológico y endoscópico, y complicaciones a partir de una muestra de pacientes en un centro de gastroenterología. Materiales y métodos: serie de casos de pacientes que ingresaron desde urgencias y fueron interconsultados al servicio de gastroenterología con diagnóstico presuntivo de CEE. Se recolectaron variables clínicas, así como características, comorbilidades, tiempo de evolución y oportunidad diagnóstica, estudios confirmatorios, y complicaciones. Resultados: 84 sujetos, 70% hombres, promedio de edad 45 (rango:17-87; SD 12,5) años. En 98,8% de los pacientes se realizó endoscopía digestiva alta de modo urgente, con estancia intrahospitalaria promedio de 2,5 días. 93% sin patología de base asociada, en 6/84 (7,14%) pacientes se documentó patología esofágica estructural o funcional. 59/84 70,2%) pacientes consultaron en las primeras 24 horas, en 57,6% se confirmó endoscópicamente presencia de cuerpo extraño. En 67/84 (79,76%) pacientes se realizó radiografía previa a endoscopia, de los cuales, 62/67 (92,5%) con resultado anormal. 70% de los CEE confirmados fueron espinas de pescado. El sitio más frecuente de localización fue en región cricofaringea en el 90% de los casos. En 66/84 (78,6%) sujetos hubo ausencia de complicaciones, seguido de laceración profunda en 10/84 (11,9%) casos. En 3/84 (3,6%) casos se identificaron complicaciones con requerimiento quirúrgico. Conclusiones: La intervención endoscópica en las primeras 24 horas es un momento oportuno para identificación de complicaciones y brindar el tratamiento indicado.

The presence of esophageal foreign body (EFB) is a common emergency in gastroenterology. The protocol for management and endoscopic intervention can be variable among institutions. Objective: to define the clinical characteristics of EFB in adults, its radiological and endoscopic diagnosis, and complications based on a sample of patients in a gastroenterology center. Materials and methods: case series of patients admitted from the emergency department and referred to the gastroenterology department with a presumptive diagnosis of EFB. Clinical variables were collected, as well as characteristics, comorbidities, time of evolution and diagnostic opportunity, confirmatory studies, and complications. Results: 84 subjects, 70% men, mean age 45 (range: 17-87; SD 12.5) years. Urgent upper endoscopy was performed in 98.8% of the patients, with an average in-hospital stay of 2.5 days. 93% had no associated underlying pathology, in 6/84 (7.14%) patients structural or functional esophageal pathology was documented. 59/84 (70.2%) patients consulted in the first 24 hours, in 57.6% the presence of foreign body was confirmed endoscopically. In 67/84 (79.76%) patients radiography was performed prior to endoscopy, of which 62/67 (92.5%) had an abnormal result. Seventy percent of confirmed EFB were fish bones. The most frequent site of localization was in the cricopharyngeal region in 90% of the cases. In 66/84 (78.6%) subjects there was absence of complications, followed by deep laceration in 10/84 (11.9%) cases. In 3/84 (3.6%) cases complications requiring surgery were identified. Conclusions: Endoscopic intervention in the first 24 hours is an opportune moment to identify complications and provide the indicated treatment.

Dolor torácico severo tras retención de cápsula inalámbrica de pH

La cápsula inalámbrica para medir el reflujo gastroesofágico o tambien conocida como cápsula de pHmetría, es una técnica utilizada en la monitorización ambulatoria del reflujo. Esta cápsula es introducida mediante una guía al esofágo y se coloca mediante un sistema de succión y anclaje a la mucosa esofágica. De alli, se comunica con un dispositivo externo mediante señales de radio para registrar la actividad del ácido gástrico en el esófago durante un período determinado de tiempo. A diferencia de la técnica convencional, que implica la inserción de un tubo a través de la nariz hasta el esófago, la cápsula inalámbrica puede ser una alternativa más cómoda y tolerable para los pacientes, lo que podría mejorar la adherencia al procedimiento. Sin embargo, algunos pacientes pueden presentar dolor torácico tras la colocación de la cápsula de pHmetría. Presentamos el caso de una mujer con cuadro clínico de reflujo gastroesofágico, con colocación capsula de pHmetría inalámbrica, lo cual generó dolor torácico severo que precisó la retirada de la cápsula vía endoscópica.

The wireless capsule to measure gastroesophageal reflux, also known as pH monitoring capsule, is a technique used in ambulatory reflux monitoring. This capsule is introduced through a guide into the esophagus and is placed using a suction system and anchored to the esophageal mucosa. From there, it communicates with an external device using radio signals to record the activity of gastric acid in the esophagus over a specified period of time. Unlike the conventional technique, which involves inserting a tube through the nose into the esophagus, the wireless capsule may be a more comfortable and tolerable alternative for patients, potentially improving adherence to the procedure. In some cases, patients may present chest pain after placement of the pH monitoring capsule, however there is little evidence about the etiology and management. We present the case of a woman with a clinical picture of gastroesophageal reflux, with pH monitoring capsule placement, which resulted in severe chest pain that required endoscopic capsule removal.

The Comparative Anatomy of the Upper Digestive System in 26 Species of Zoophagous-Polyphagous Palearctic Birds / Anatomía Comparada del Sistema Digestivo Superior en 26 Especies de Aves Paleárticas Zoófagas-Polífagas

SUMMARY: Birds are the most diversified organisms on Earth, with species covering various niches in each major biome, being essential to understand the modern ecosystem. This study concentrates on the diversification of the anatomical structure of the upper digestive tract for 26 species of zoophage-polyphagous birds and the anatomical differences in the digestive system to reveal aspects related to their evolution and diversification. The trophic spectrum of the selected birds includes several categories of food, or, as in the case of strictly carnivorous birds, to a single food category. After performing the dissections, the digestive tract was separated from the carcass and each digestive segment was measured and analysed. In this study, it was demonstrated that the birds' feeding behaviour influence the macroscopic particularities of the digestive system, more visible in the cranial portion (oropharyngeal cavity, esophagus, proventriculus and gizzard), with little descriptive information in the literature. The tongue is poorly developed and immobile in piscivorous birds, while the tongue of insectivorous birds is long and moves considerably away from the tip of the bill. The esophagus was stretchable and presents longitudinal folds on its entire surface in piscivorous species and not extensible in insectivorous birds.

Las aves son los organismos más diversificados de la Tierra, con especies que cubren varios nichos en cada bioma principal, siendo esenciales para comprender el ecosistema moderno. Este estudio se concentra en la diversificación de la estructura anatómica del tracto digestivo superior para 26 especies de aves zoófago-polífagas y las diferencias anatómicas en el sistema digestivo para revelar aspectos relacionados con su evolución y diversificación. El espectro trófico de las aves seleccionadas incluye varias categorías de alimentos o, como en el caso de las aves estrictamente carnívoras, una sola categoría de alimentos. Después de realizar las disecciones, se separó el tracto digestivo de la canal y se midió y analizó cada segmento digestivo. En este estudio se demostró que el comportamiento alimentario de las aves influye en las particularidades macroscópicas del sistema digestivo, más visibles en la porción craneal (cavidad orofaríngea, esófago, proventrículo y molleja), con poca información descriptiva en la literatura. En las aves piscívoras, la lengua está poco desarrollada e inmóvil, mientras que la lengua de las aves insectívoras es larga y se aleja considerablemente de la punta del pico. El esófago era estirable y presentaba pliegues longitudinales en toda su superficie en especies piscívoras y no extensible en aves insectívoras.

Reemplazo esofágico mínimamente invasivo con tubo de Akiyama en un paciente pediátrico con quemadura esofágica / Minimally invasive esophageal replacement with Akiyama tube in a pediatric patient with esophageal burn

Introducción. La ingesta de cáusticos continúa siendo un problema de salud pública en los países en vía de desarrollo, por lo que a veces es necesario realizar un reemplazo esofágico en estos pacientes. Aún no existe una técnica estandarizada para este procedimiento. Caso clínico. Masculino de 10 años con estenosis esofágica por ingesta de cáusticos, quien no mejoró con las dilataciones endoscópicas. Se realizó un ascenso gástrico transhiatal por vía ortotópica mediante cirugía mínimamente invasiva como manejo quirúrgico definitivo .Discusión. Actualmente existen varios tipos de injertos usados en el reemplazo esofágico. La interposición colónica y gástrica son las que cuentan con mayores estudios, mostrando resultados similares. Conclusiones. La elección del tipo y posición del injerto debe ser individualizada, tomando en cuenta las características de las lesiones y la anatomía de cada paciente para aumentar la tasa de éxito.

Introduction. The ingestion of caustics continues to be a public health problem in developing countries, which is why sometimes is necessary to perform an esophageal replacement in these patients. There is still no standardized technique for this procedure. Clinical case. A 10-year-old male with esophageal stricture due to caustic ingestion, who did not improve with endoscopic dilations. A laparoscopic transhiatal gastric lift was performed orthotopically as definitive surgical management using minimally invasive surgery. Discussion. Currently there are several types of grafts used in esophageal replacement. Colonic and gastric interposition are the ones that have the most studies, showing similar results. Conclusions. Choice of type and position of the graft must be individualized, taking into account the characteristics of the lesions and anatomy of each patient, in order to increase the success rate.

Magnetic sphincter augmentation device for gastroesophageal reflux disease: effective, but postoperative dysphagia and risk of erosion should not be underestimated. a systematic review and meta-analysis / Dispositivo magnético no esfincter para doença do refluxo gastroesofágico: eficaz, mas a disfagia pós-operatória e o risco de erosão não devem ser subestimados. uma revisão sistemática e meta-análise

ABSTRACT BACKGROUND: Magnetic ring (MSA) implantation in the esophagus is an alternative surgical procedure to fundoplication for the treatment of gastroesophageal reflux disease. AIMS: The aim of this study was to analyse the effectiveness and safety of magnetic sphincter augmentation (MSA) in patients with gastroesophageal reflux disease (GERD). METHODS: A systematic literature review of articles on MSA was performed using the Medical Literature Analysis and Retrieval System Online (Medline) database between 2008 and 2021, following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. A random-effect model was used to generate a pooled proportion with 95% confidence interval (CI) across all studies. RESULTS: A total of 22 studies comprising 4,663 patients with MSA were analysed. Mean follow-up was 27.3 (7-108) months. The weighted pooled proportion of symptom improvement and patient satisfaction were 93% (95%CI 83-98%) and 85% (95%CI 78-90%), respectively. The mean DeMeester score (pre-MSA: 34.6 vs. post-MSA: 8.9, p=0.03) and GERD-HRQL score (pre-MSA: 25.8 vs. post-MSA: 4.4, p<0.0001) improved significantly after MSA. The proportion of patients taking proton pump inhibitor (PPIs) decreased from 92.8 to 12.4% (p<0.0001). The weighted pooled proportions of dysphagia, endoscopic dilatation and gas-related symptoms were 18, 13, and 3%, respectively. Esophageal erosion occurred in 1% of patients, but its risk significantly increased for every year of MSA use (odds ratio — OR 1.40, 95%CI 1.11-1.77, p=0.004). Device removal was needed in 4% of patients. CONCLUSIONS: Although MSA is a very effective treatment modality for GERD, postoperative dysphagia is common and the risk of esophageal erosion increases over time. Further studies are needed to determine the long-term safety of MSA placement in patients with GERD.

RESUMO RACIONAL: A implantação de anel magnético (AM) no esôfago é um procedimento cirúrgico alternativo à fundoplicatulra, para o tratamento da doença do refluxo gastroesofágico. OBJETIVOS: O objetivo deste estudo foi analisar a eficácia e segurança do anel magnético em pacientes com doença do refluxo gastroesofágico (DRGE). MÉTODOS: Uma revisão sistemática da literatura de artigos sobre AM foi realizada usando o banco de dados Medline entre 2008 e 2021, seguindo as diretrizes PRISMA. Um modelo de efeito aleatório foi usado para gerar uma proporção agrupada com intervalo de confiança (IC) de 95% em todos os estudos. RESULTADOS: Um total de 22 estudos compreendendo 4.663 pacientes submetidos à colocação do AM foram analisados. O seguimento médio foi de 27,3 (7-108) meses. A proporção ponderada de melhora dos sintomas e satisfação do paciente foi de 93% (IC95% 83-98%) e 85% (IC95% 78-90%), respectivamente. A pontuação média de DeMeester (pré-AM: 34,6 versus pós-AM: 8,9, p=0,03) e pontuação GERD-HRQL (pré-AM: 25,8 versus pós-AM: 4,4, p<0,0001) melhoraram significativamente após a colocação do anel. A proporção de pacientes em uso de inbidor de bomba de prótons (IBP) diminuiu de 92,8% para 12,4% (p<0,0001). A erosão esofágica ocorreu em 1% dos pacientes, o risco aumentou significativamente para cada ano de uso do AM (OR 1,40; IC95% 1,11-1,77, p=0,004). A remoção do dispositivo foi necessária em 4% dos pacientes. CONCLUSÕES: O AM é uma modalidade de tratamento eficaz para a DRGE. A disfagia pós-operatória é comum, e o risco de erosão esofágica aumenta com o tempo.

Endoscopic ablation combined with fundoplication plus acid suppression-duodenal diversion procedure for long segment barrett´s esophagus: early and long-term outcome / Ablação endoscópica combinada com fundoplicatura associada a diversão duodenal no esôfago de barrett longo: resultados precoce e de longo prazo

ABSTRACT BACKGROUND: The addition of endoscopic ablative therapy plus proton pump inhibitors or fundoplication is postulated for the treatment of patients with long-segment Barrett´s esophagus (LSBE); however, it does not avoid acid and bile reflux in these patients. Fundoplication with distal gastrectomy and Roux-en-Y gastrojejunostomy is proposed as an acid suppression-duodenal diversion procedure demonstrating excellent results at long-term follow-up. There are no reports on therapeutic strategy with this combination. AIMS: To determine the early and long-term results observed in LSBE patients with or without low-grade dysplasia who underwent the acid suppression-duodenal diversion procedure combined with endoscopic therapy. METHODS: Prospective study including patients with endoscopic LSBE using the Prague classification for circumferential and maximal lengths and confirmed by histological study. Patients were submitted to argon plasma coagulation (21) or radiofrequency ablation (31). After receiving treatment, they were monitored at early and late follow-up (5-12 years) with endoscopic and histologic evaluation. RESULTS: Few complications (ulcers or strictures) were observed after the procedure. Re-treatment was required in both groups of patients. The reduction in length of metaplastic epithelium was significantly better after radiofrequency ablation compared to argon plasma coagulation (10.95 vs 21.15 mms for circumferential length; and 30.96 vs 44.41 mms for maximal length). Intestinal metaplasia disappeared in a high percentage of patients, and histological long-term results were quite similar in both groups. CONCLUSIONS: Endoscopic procedures combined with fundoplication plus acid suppression with duodenal diversion technique to eliminate metaplastic epithelium of distal esophagus could be considered a good alternative option for LSBE treatment.

RESUMO RACIONAL: A adição de terapia ablativa endoscópica associado a inibidores da bomba de prótons ou fundoplicatura tem sido postulada para o tratamento de pacientes com esôfago de Barrett de segmento longo (EBSL), no entanto, essa conduta não evita o refluxo ácido/biliar nesses pacientes. A fundoplicatura com gastrectomia distal e gastrojejunostomia em Y de Roux (FGD-Y) foi proposta como procedimento de supressão de ácido, demonstrando excelentes resultados no seguimento a longo prazo. Não há relatos na literature com a combinação dessa estratégia terapêutica. OBJETIVOS: Determinar os resultados precoces e a longo prazo observados em pacientes com EBSL com ou sem dysplasia de baixo grau, submetidos a FGD-Y, combinado com terapia endoscópica. MÉTODOS: Estudo prospectivo incluindo pacientes com EBSL, empregando a classificação de Praga, sendo o comprimento circunferencial (C) e máximo (M) e confirmado por estudo histológico. Os pacientes foram submetidos à coagulação com plasma de argônio (CPA, 21 pacientes) ou ablação por radiofrequência (ARF, 31 pacientes). Após o tratamento, eles foram seguidos precoce e tardiamente (5-12 anos), mediante avaliação endoscópica e histológica. RESULTADOS: Foram observadas poucas complicações após o procedimento (úlcera ou estenose). Re-tratamento foi necessário em ambos os grupos de pacientes. A redução do comprimento do epitélio metaplásico foi significativamente melhor após ARF em comparação com CPA (10,95 versus 21,15 mm para C e 30,96 versus 44,41 mm para M). A metaplasia intestinal desapareceu em elevada porcentagem de pacientes, e os resultados histológicos a longo prazo foram bastante semelhantes em ambos os grupos. CONCLUSÕES: Procedimentos endoscópicos combinados com fundoplicatura e gastrectomia distal e gastrojejunostomia em Y de Roux, para eliminar o epitélio metaplásico do esôfago distal podem ser considerados uma boa opção alternativa para o tratamento da EBSL.

Development of adenocarcinoma after radiofrequency ablation of barrett's esophagus associated to fundoplication and suppression-duodenal diversion procedure: a lesson to be learned / Adenocarcinoma em esôfago de barrett após ablação por radiofrequência associada a fundoplicatura e diversão duodenal

ABSTRACT Despite endoscopic eradication therapy being an effective and durable treatment for Barrett's esophagus-related neoplasia, even after achieving initial successful eradication, these patients remain at risk of recurrence and require ongoing routine examinations. Failure of radiofrequency ablation and argon plasma coagulation is reported in 10-20% of cases.

RESUMO Apesar de a terapia de erradicação endoscópica ser um tratamento eficaz e durável para a neoplasia relacionada ao esôfago de Barrett (BE), mesmo após a erradicação inicial bem-sucedida, esses pacientes permanecem em risco de recorrência e requerem exames de rotina contínuos. A falha na ablação por radiofrequência e na coagulação com plasma de argônio é relatada em 10-20% dos casos.

Can COVID-19 impact the natural history of paracoccidioidomycosis? Insights from an atypical chronic form of the mycosis

ABSTRACT Paracoccidioidomycosis (PCM) is a systemic fungal infection caused by Paracoccidioides spp. It can occur as an acute/subacute form (A/SAF), a chronic form (CF) and rarely as a mixed form combining the features of the two aforementioned forms in an immunocompromised patient. Here, we report a 56-year-old male patient with CF-PCM who presented with atypical manifestations, including the development of an initial esophageal ulcer, followed by central nervous system (CNS) lesions and cervical and abdominal lymphatic involvement concomitant with severe SARS-CoV-2 infection. He was HIV-negative and had no other signs of previous immunodeficiency. Biopsy of the ulcer confirmed its mycotic etiology. He was hospitalized for treatment of COVID-19 and required supplemental oxygen in the intensive unit. The patient recovered without the need for invasive ventilatory support. Investigation of the extent of disease during hospitalization revealed severe lymphatic involvement typical of A/SAF, although the patient`s long history of high-risk exposure to PCM, and lung involvement typical of the CF. Esophageal involvement is rare in non-immunosuppressed PCM patients. CNS involvement is also rare. We suggest that the immunological imbalance caused by the severe COVID-19 infection may have contributed to the patient developing atypical severe CF, which resembles the PCM mixed form of immunosuppressed patients. Severe COVID-19 infection is known to impair the cell-mediated immune response, including the antiviral response, through T-lymphopenia, decreased NK cell counts and T-cell exhaustion. We hypothesize that these alterations would also impair antifungal defenses. Our case highlights the potential influence of COVID-19 on the course of PCM. Fortunately, the patient was timely treated for both diseases, evolving favorably.

Corps étrangers chroniques dans l'œsophage chez l'enfant / Chronic foreign bodies in the oesophagus in children

Les ingestions de corps étrangers sont des accidents fréquents en pédiatrie. La plupart sont sans grande conséquence sauf ceux qui sont enclavés dans l'œsophage. Nous rapportons 2 cas de pile bouton intraœsophagienne chez 2 enfants âgés de: 4ans de sexe masculin et 2 ans de sexe féminin. Le motif de consultation dans les deux cas était la dysphagie aux solides. La fibroscopie broncho-oesophagienne a été effectuée dans les 2 cas avec échec d'extraction conduisant à une extraction chirurgicale par voie de thoracotomie chez le garçon et de cervicotomie chez la fille. Une sténose œsophagienne est survenue à 2 mois dans les suites opératoires chez le garçon. L'évolution a été favorable après dilatation aux bougies de Rehbein modifiées. Chez la fille en postopératoire un œdème laryngé est survenu et a nécessité des séances de nébulisations. L'évolution a été favorable chez les 2 enfants avec un recul de 5 ans et de 2 mois. Conclusion: Les piles boutons sont des corps étrangers particuliers qu'il faut extraire en urgence. L'oesophagoscopie reste le moyen le plus fréquemment employé mais la chirurgie reste le dernier recourt avec des possibilités de complication.

Ingestion of foreign bodies is a common accident in paediatrics. Most of them are of little consequence except for those that are enclosed in the esophagus. We report 2 cases of intraesophageal button stacks in 2 children aged 4 years' male and 2 years female. The reason for consultation in both cases was solid dysphagia. Bronchoesophageal fibroscopy was performed in both cases with failed extraction leading to surgical extraction by thoracotomy in boys and cervicotomy in girls. Esophageal stenosis occurred at 2 months of age in the postoperative period in boys. The development was favourable after expansion at the modified Rehbein candles. In the postoperative girl, laryngeal edema occurred and required nebulization sessions. The evolution was favorable in the 2 children with a follow-up of 5 years and 2 months. Conclusion: Button batteries are special foreign bodies that need to be removed urgently. Esophagoscopy remains the most frequently used method, but surgery remains the last resort with the possibility of complications.

Investigation of the histopathological level of Ki-67, caspase-3 expressions of the effects of hesperidin on wound healing in the rat esophagus

Purpose: The effects of hesperidin application on the wound caused by esophageal burns were investigated in this study. Methods: Wistar albino rats were divided into three groups: Control group: only 1 mL of 0.09% NaCl was administered i.p. for 28 days; Burn group: An alkaline esophageal burn model was created with 0.2 mL of 25% NaOH orally by gavage­1 mL of 0.09% NaCl was administered i.p. for 28 days; Burn+Hesperidin group: 1 mL of 50 mL/kg of hesperidin was given i.p. for 28 days to rats after burn injury. Blood samples were collected for biochemical analysis. Esophagus samples were processed for histochemical staining and immunohistochemistry. Results: Malondialdehyde (MDA) and myeloperoxidase (MPO) levels were significantly increased in Burn group. Glutathione (GSH) content and histological scores of epithelialization, collagen formation, neovascularization was decreased. After hesperidin treatment, these values were significantly improved in the Burn+Hesperidin group. In the Burn group, epithelial cells and muscular layers were degenerated. Hesperidin treatment restored these pathologies in Burn+Hesperidin group. Ki-67 and caspase-3 expressions were mainly negative in control group; however, the expression was increased in the Burn group. In the Burn+Hesperidin group, Ki-67 and caspase-3 immune activities were reduced. Conclusion: Hesperidin dosage and application methods can be developed as an alternative treatment for burn healing and treatment.

Analysis of risk factors of radiation-induced toxicity in limited-stage small cell lung cancer treated with hypofractionated intensity-modulated radiotherapy / 中华肿瘤杂志

Objective: To compare the incidence of radiation-related toxicities between conventional and hypofractionated intensity-modulated radiation therapy (IMRT) for limited-stage small cell lung cancer (SCLC), and to explore the risk factors of hypofractionated radiotherapy-induced toxicities. Methods: Data were retrospectively collected from consecutive limited-stage SCLC patients treated with definitive concurrent chemoradiotherapy in Cancer Hospital of Chinese Academy of Medical Sciences from March 2016 to April 2022. The enrolled patients were divided into two groups according to radiation fractionated regimens. Common Terminology Criteria for Adverse Events (CTCAE, version 5.0) was used to evaluate the grade of radiation esophagus injuries and lung injuries. Logistic regression analyses were used to identify factors associated with radiation-related toxicities in the hypofractionated radiotherapy group. Results: Among 211 enrolled patients, 108 cases underwent conventional IMRT and 103 patients received hypofractionated IMRT. The cumulative incidences of acute esophagitis grade ≥2 [38.9% (42/108) vs 35.0% (36/103), P=0.895] and grade ≥ 3 [1.9% (2/108) vs 5.8% (6/103), P=0.132] were similar between conventional and hypofractionated IMRT group. Late esophagus injuries grade ≥2 occurred in one patient in either group. No differences in the cumulative incidence of acute pneumonitis grade ≥2[12.0% (13/108) vs 5.8% (6/103), P=0.172] and late lung injuries grade ≥2[5.6% (6/108) vs 10.7% (11/103), P=0.277] were observed. There was no grade ≥3 lung injuries occurred in either group. Using multiple regression analysis, mean esophageal dose ≥13 Gy (OR=3.33, 95% CI: 1.23-9.01, P=0.018) and the overlapping volume between planning target volume (PTV) and esophageal ≥8 cm(3)(OR=3.99, 95% CI: 1.24-12.79, P=0.020) were identified as the independent risk factors associated with acute esophagitis grade ≥2 in the hypofractionated radiotherapy group. Acute pneumonitis grade ≥2 was correlated with presence of chronic obstructive pulmonary disease (COPD, P=0.025). Late lung injuries grade ≥2 was correlated with tumor location(P=0.036). Conclusions: Hypofractionated IMRT are tolerated with manageable toxicities for limited-stage SCLC patients treated with IMRT. Mean esophageal dose and the overlapping volume between PTV and esophageal are independently predictive factors of acute esophagitis grade ≥2, and COPD and tumor location are valuable factors of lung injuries for limited-stage SCLC patients receiving hyofractionated radiotherapy. Prospective studies are needed to confirm these results.

Nutrition management by a multidisciplinary team for prevention of nutritional deficits and morbidity following esophagectomy

This study evaluated the effects of perioperative nutrition management by a multidisciplinary team on nutrition and postoperative complications of patients with esophageal cancer. A total of 239 patients with esophageal cancer who underwent esophagectomy and gastric conduit reconstruction for esophageal or esophagogastric junction cancer between February 2019 and February 2020 were included in the study. They were divided into the experimental group (120 patients) and the control group (119 patients) using the random number table method. Control group patients received routine diet management and experimental group patients received perioperative nutrition management by a multidisciplinary team. The differences of nutriture and postoperative complications between the two groups were compared. At 3 and 7 days after surgery, the experimental group patients had higher total protein and albumin levels (P<0.05), shorter postoperative anal exhaust time (P<0.05), lower incidence of postoperative gastrointestinal adverse reactions, pneumonia, anastomotic fistula, hypoproteinemia (P<0.05), and lower hospitalization costs (P<0.05) than the control group. Nutrition management by a multidisciplinary team effectively improved the nutriture of patients, promoted the rapid recovery of postoperative gastrointestinal function, reduced postoperative complications, and reduced hospitalization costs.

Seguridad de la endoscopia y biopsia esofágica en un paciente con esofagitis eosinofílica y enfermedad de Von Willebrand / Safety of esophageal endoscopy and biopsy in a patient with eosinophilic esophagitis and Von Willebrand disease

La esofagitis eosinofílica (EoE) es una enfermedad causada por una respuesta inmune frente a antígenos alimentarios en contacto con la mucosa esofágica; por su parte, la enfermedad de Von Willebrand (EVW) es el trastorno hemorrágico hereditario más común en los seres humanos. La característica central de todos los tipos de EVW, es la presencia de cantidades reducidas o de formas anormales del factor de Von Willebrand (FVW) en el torrente sanguíneo. Debido a que no se han reportado casos previos de EVW tipo 2A asociada a EoE, se describe este caso clínico con el objetivo principal de dar a conocer el hallazgo casual de estas dos patologías, la seguridad de la evaluación por endoscopia de vías digestivas altas y el pronóstico de posibles complicaciones

Eosinophilic esophagitis (EoE) is a disease caused by an immune response against food antigens in contact with the esophageal mucosa; alternatively, Von Willebrand disease (VWD) is the most common inherited bleeding disorder in humans. The central characteristic of all types of VWD is the presence of reduced amounts or abnormal forms of VWF in the bloodstream. Since no previous cases of VWD type 2A associated to EoE have been reported, this clinical case is described with the main objective to present the coincidental finding of these two pathologies, the safety of the evaluation by upper gastrointestinal endoscopy, and the prognosis of possible complications

Resultado da miotomia endoscópica peroral (POEM) em acalasia avançada em um seguimento mediano de 17 meses / Outcome of per oral endoscopic myotomy (poem) in sigmoid achalasia at a median follow up of 17 months

ABSTRACT Background: Advanced achalasia cardia (AC) represents the end stage in the natural history of AC. Role of per oral endoscopic myotomy (POEM) in this technically difficult subset is emerging. Methods: Retrospective review of the patients who had undergone POEM for advanced AC with sigmoid esophagus. We assessed the technical success, clinical success and adverse event rate. Pre and post POEM Eckardt score (ES), integrated relaxation pressure-4sec (IRP-4), lower oesophageal sphincter pressure (LESP) and height and width of barium column at 5 minutes were noted. Results: Of the 85 patients who underwent POEM for AC, 10 patients had advanced AC with sigmoid esophagus of which eight were sigmoid and two were advanced sigmoid. The clinical and technical success was 100% with significant reduction of ES, IRP-4, LESP and height and width of barium column at 5 minutes. One patient had a minor adverse event in the form of mucosal injury that was closed with hemoclips. At a median follow up of 17 months there was no recurrence. Conclusion: Our study demonstrates POEM to be a safe and effective modality of treatment in this technically difficult subset of AC with sigmoid morphology.

RESUMO Contexto: Acalasia cárdia avançada representa o estágio final na história natural do megaesôfago. Está emergindo o papel da miotomia endoscópica peroral (POEM) neste subconjunto tecnicamente difícil. Métodos: Foi realizada uma revisão retrospectiva dos pacientes submetidos a POEM para tratamento do megaesôfago avançado. Avaliamos o sucesso técnico, o sucesso clínico e a taxa de eventos adversos. O escore de Eckardt, pré e pós POEM, a pressão integral de relaxamento de 4 seg (IRP-4), a pressão do esfíncter inferior do esôfago e a altura e largura da coluna de bário em 5 minutos, foram anotadas. Resultados: Dos 85 pacientes submetidos a POEM para acalasia cárdia, 10 pacientes apresentaram acalasia cárdia avançado com esôfago com aspecto sigmoide, dos quais dois eram muito avançados. O sucesso clínico e técnico foi de 100% com redução significativa do escore de Eckardt, do IRP-4, da pressão do esfíncter inferior do esôfago e da altura e largura da coluna bário em 5 minutos. Um paciente teve um pequeno evento adverso na forma de lesão mucosa que foi fechada com hemoclipes. Em um seguimento mediano de 17 meses não houve recorrência. Conclusão: Nosso estudo demonstra que a POEM é uma modalidade segura e eficaz de tratamento neste subconjunto tecnicamente difícil de megaesôfago com morfologia sigmoide.

Primary carcinoma esophagus with unusual synchronous second malignancies: A case series

Multiple primary cancer is no longer a rarity. As life expectancy has increased, more individuals are living long enough to develop not only one but also two or more cancers. Herein, we report on three cases of synchronous malignancies associated with the primary esophagus cancer. All three patients posed a challenge for the treatment. These patients carry a dismal prognosis so early diagnosis of subsequent cancer at a curable stage by regular follow-up is encouraged. The early investigation of new symptoms and signs may help to diagnose, initiate early treatment, and reduce the number of deaths from subsequent primary cancers in patients.

Esófago negro asociado a estado de choque. A propósito de un caso / Black esophagus associated with shock. About a case

Resumen La necrosis esofágica aguda, también conocida como esófago negro, es una patología poco común que se diagnostica mediante endoscopia en la que se muestra una mucosa esofágica de aspecto negro. Su causa es desconocida, pero se le atribuye un origen multifactorial. Debe considerarse una lesión esofágica de origen isquémico. Se presenta el caso de un paciente de 56 años con síntomas respiratorios sugestivos de proceso infeccioso grave, con un cuadro clínico rápidamente progresivo y requerimiento de aseguramiento de la vía aérea, soporte vasopresor y orgánico multimodal, estudio endoscópico por clínica de hemorragias de vías digestivas altas con evidencia de lesiones compatibles con necrosis esofágica aguda. A pesar de manejo multimodal en unidad de cuidados intensivos el paciente fallece al día 34 desde su ingreso hospitalario.

Abstract Acute esophageal necrosis, also known as the black esophagus, is a rare pathology diagnosed by endoscopy that shows a black-looking esophageal mucosa. Its cause is unknown, but a multifactorial origin is attributed to it. An esophageal lesion of ischemic origin should be considered. We present the case of a 56-year-old patient with respiratory symptoms suggestive of a severe infectious process, with a rapidly progressive clinical picture and requirement of airway security, multimodal vasopressor, and organic support, and an endoscopic study due to clinical symptoms of upper digestive tract bleeding with evidence of lesions compatible with acute esophageal necrosis. Despite multimodal management in the intensive care unit, the patient died 34 days after hospital admission.

Caracterización clinicoepidemiológica, diagnóstica e histopatológica de pacientes tratados con esofagectomía por cáncer de esófago / Clinical epidemiological, diagnostic, histological and pathological characterization of patients treated with esophagectomy due to esophagus cancer

Introducción: El cáncer de esófago se manifiesta clínicamente en etapas avanzadas y presenta gran letalidad. Objetivo: Caracterizar a los pacientes operados de cáncer de esófago según variables epidemiológicas, clínicas, diagnósticas e histopatológicas. Métodos: Se realizó un estudio observacional, descriptivo y transversal de 87 pacientes con cáncer de esófago, operados en el Servicio de Cirugía General del Hospital Provincial Docente Clinicoquirúrgico Saturnino Lora de Santiago de Cuba, en el periodo 2014-2018. Resultados: Dicha afección predominó en pacientes del sexo masculino (94,2 %) entre los 65 y 74 años de edad (37,9 %); el tipo histológico más frecuente fue el carcinoma epidermoide (89,6 %) y la localización en el tercio medio (49,4 %). Los hábitos tóxicos que primaron fueron el tabaquismo (87,4 %) y el consumo de alcohol (75,8 %). La disfagia y la pérdida de peso se manifestaron en 73,5 y 66,6 % de la serie, respectivamente. El diagnóstico se realizó mediante imágenes, tales como esofagograma, tomografía contrastada de tórax, abdomen y pelvis; así como por medio de endoscopia y biopsia. Conclusiones: Se demostró que los hombres son los más afectados y es más frecuente el diagnóstico en mayores de 60 años de edad. Se observó el vínculo con el hábito de fumar y el consumo de alcohol. La disfagia es el síntoma más común y tardío de la enfermedad. El estudio de las características clínico-histológicas de los pacientes con cáncer de esófago permite un adecuado enfoque diagnóstico de esta afección, así como el desarrollo de acciones de salud preventivas sobre los principales factores de riesgo identificados.

Introduction: The esophagus cancer is clinically manifested in advanced stages and presents great lethality. Objective: To characterize the patients operated on esophagus cancer according to epidemiological, clinical, diagnostic, histological and pathological variables. Methods: An observational, descriptive and cross-sectional study of 87 patients with esophagus cancer was carried out; they were operated in the General Surgery Service of Saturnino Lora Teaching Clinical Surgical Provincial Hospital in Santiago de Cuba, in the period 2014-2018. Results: This affection prevailed in patients from the male sex (94.2 %) between the 65 and 74 years (37.9 %); the most frequent histhologic type was the squamous cell carcinoma (89.6 %) and the localization in the mean third (49.4 %). The toxic habits that prevailed were nicotine addiction (87.4 %) and consumption of alcohol (75.8 %). The dysphagia and loss of weight showed in 73.5 and 66.6 % of the series, respectively. The diagnosis was carried out by means of images, such as esophagogram, chest, abdomen and pelvis contrast tomography, as well as by means of endoscopy and biopsy. Conclusions: It was demonstrated that men are the most affected and it is more frequent the diagnosis in those over 60 years. The link with the habit of smoking and consumption of alcohol was observed. The dysphagia is the most common and late symptom of the disease. The study of clinical, histological and pathological characteristics of patients with esophagus cancer allows an appropriate diagnostic approach of this affection, as well as the development of preventive health actions about the main identified risk factors.

Esofagotomía y cierre primario por cuerpo extraño en esófago superior / Esophagotomy and primary closure due to foreign body in the upper esophagus

RESUMEN Los cuerpos extraños en el esófago son un problema frecuente en urgencias, debido la mayoría de las veces a ingestión accidental. Presentamos el caso de una paciente femenina de 50 años, sin antecedentes patológicos, que consulta por presentar la ingesta de prótesis dental mientras almorzaba, con posterior disfagia, odinofagia y dolor cervical. Se le realizan radiografías y tomografía computarizada (TC) donde se evidencia imagen radiopaca en esófago cervical. Se interconsulta con el Servicio de Gastroenterología, dada la imposibilidad de extracción de la prótesis por vía endoscópica. Se realiza luego cervicotomía lateral izquierda de emergencia, con esofagotomía, extracción del cuerpo extraño y cierre primario del esófago. La obstrucción del esófago por cuerpos extraños puede ocasionar muchas complicaciones. La consecuente demora en el tratamiento puede llevar a un marcado aumento de la mortalidad. Por eso, en este caso, se prioriza la cirugía ante un riesgo elevado de perforación y hemorragia.

ABSTRACT Esophageal foreign bodies are a common problem in the emergency department, usually due to accidental ingestion. We report the case of a 50-year-old otherwise healthy female patient who sought medical care due to dysphagia, odynophagia and cervical pain after swallowing a partial denture while having lunch. The patient underwent X-rays and a computed tomography (CT) scan which showed a radiopaque image in the upper esophagus. After a failed attempt to remove the denture through endoscopy, surgery was decided via a left lateral emergency cervicotomy with esophagotomy, foreign body removal and primary closure of the esophagus. Esophageal obstruction due to foreign bodies may cause many complications. Treatment delays may result in increased mortality. Thus, in this case we prioritized surgery due to high risk of perforation and bleeding.

An unusual case of extensive polypoid high-grade dysplasia in Barrett's esophagus

Barrett's esophagus (BE) is a known precursor of dysplasia and adenocarcinoma. Endoscopic resection and surgery are the techniques used to treat these kinds of lesions. However, endoscopic resection is considered the first choice for the management of superficial lesions. Dysplasia in BE most commonly appears like a flat lesion but here we describe an unusual case of dysplasia and superficial adenocarcinoma looking like an extensive polypoid lesion.

El esófago de Barrett (EB) es un precursor conocido de displasia y adenocarcinoma. La resección endoscópica y la cirugía son las técnicas utilizadas para tratar este tipo de lesiones. Sin embargo, la resección endoscópica se considera la primera opción para el manejo de las lesiones superficiales. La displasia en EB aparece más comúnmente como una lesión plana, pero aquí describimos un caso inusual de displasia y adenocarcinoma superficial que parece una lesión polipoide extensa.
