Efficacy and safety of submucosal tunneling endoscopic resection for multiple submucosal tumors of upper gastrointestinal tract / 中华消化内镜杂志

In order to evaluate the efficacy and safety of submucosal tunneling endoscopic resection (STER) for the treatment of multiple submucosal tumors (SMT) in the upper gastrointestinal tract, data of 24 cases with upper gastrointestinal SMT (including 56 SMT lesions) treated at Taizhou Municipal Hospital and Shanghai East Hospital from January 2016 to June 2021 were collected for retrospective observation. The treatment effect, occurrence of major adverse events and follow-up results were analyzed. The results showed that 19 cases (79.2%) underwent tumor resection through one tunnel, and 5 cases (20.8%) underwent tumor resection through two tunnels. The length of the tunnel was 3-12 cm, with an average of 6.2 cm. The surgical time ranged from 19 to 130 minutes, with an average of 55.6 minutes. The overall resection rate was 89.29% (50/56). The hospitalization time was 2-7 days, with an average of 3.5 days. Major adverse events occurred in 2 cases (8.3%), all of which were mucosal injuries, and were cured with titanium clips and self expanding metal sealing stents. During a follow-up period of 6-64 months, with an average of 32.0 months, there was no residual tumor, tumor implantation tunnel, local recurrence, distant metastasis or death. To sum up, STER is safe and feasible for the treatment of multiple SMT in the upper gastrointestinal tract. The main resection method is single tunnel, and double tunnel is required for multiple SMT far apart.

CHAMPS score in predicting mortality of patients with acute nonvariceal upper gastrointestinal bleeding

SUMMARY OBJECTIVE: The aim of this study was to evaluate the performance of the Charlson Comorbidity Index ≥2, in-hospital onset, albumin <2.5 g/dL, altered mental status, Eastern Cooperative Oncology Group performance status ≥2, steroid use score in predicting mortality in patients with nonvariceal upper gastrointestinal bleeding and compare it with the Glasgow-Blatchford score; the albumin, international normalized ratio; alteration in mental status, systolic blood pressure, and age 65 score; the age, blood tests, and comorbidities score; and Complete Rockall score. METHODS: The data of patients with acute upper gastrointestinal bleeding who visited the emergency department during the study period were obtained from the hospital automation system by using the classification of disease codes and analyzed in this retrospective study. Adult patients with endoscopically confirmed nonvariceal upper gastrointestinal bleeding were included in the study. Patients with bleeding from the tumor, bleeding after endoscopic resection, or missing data were excluded. The prediction accuracy of the Charlson Comorbidity Index ≥ 2, in-hospital onset, albumin < 2.5 g/dL, altered mental status, Eastern Cooperative Oncology Group performance status ≥ 2, steroid use score was calculated using the area under the receiver operating characteristic curve and compared with that of Glasgow-Blatchford score, the albumin, international normalized ratio; alteration in mental status, systolic blood pressure, and age 65 score, the age, blood tests, and comorbidities score, and Complete Rockall score. RESULTS: A total of 805 patients were included in the study, and the in-hospital mortality rate was 6.6%. The performance of the Charlson Comorbidity Index ≥ 2, in-hospital onset, albumin < 2.5 g/dL, altered mental status, Eastern Cooperative Oncology Group performance status ≥ 2, steroid use score (area under the receiver operating characteristic curve 0.812, 95%CI 0.783-0.839) was better than Glasgow-Blatchford score (area under the receiver operating characteristic curve 0.683, 95%CI 0.650-0.713, p=0.008), and similar to the the age, blood tests, and comorbidities score (area under the receiver operating characteristic curve 0.829, 95%CI 0.801-0.854, p=0.563), the albumin, international normalized ratio; alteration in mental status, systolic blood pressure, and age 65 score (area under the receiver operating characteristic curve 0.794, 95%CI 0.764-0.821, p=0.672), and Complete Rockall score (area under the receiver operating characteristic curve 0.761, 95%CI 0.730-0.790, p=0.106). CONCLUSION: The performance of the Charlson Comorbidity Index ≥ 2, in-hospital onset, albumin < 2.5 g/dL, altered mental status, Eastern Cooperative Oncology Group performance status ≥ 2, steroid use score in predicting in-hospital mortality for our study population is better than Glasgow-Blatchford score and similar to the the age, blood tests, and comorbidities score, the albumin, international normalized ratio; alteration in mental status, systolic blood pressure, and age 65 score, and Complete Rockall score.

Successful endoscopic removal of a swallowed toothbrush, a therapeutic challenge. A case report / Extracción endoscópica exitosa de un cepillo de dientes, un reto terapéutico. Reporte de caso

Abstract Introduction: Toothbrush swallowing, whether voluntary or accidental, is a rare event and must be handled as an emergency, because these foreign bodies, due to their length and hardness, are not expected to pass completely through the digestive tract and may cause serious complications. Case presentation: A 22-year-old woman with an eating disorder (bulimia nervosa) involuntarily swallowed a toothbrush while inducing vomiting. Unfortunately, after the initial assessment in the emergency department, and due to the lack of symptoms, her psychiatric history, and the fact the toothbrush was not observed in imaging studies, she was discharged. Due to the patient's insistence that she was telling the truth, she was referred to a secondary healthcare institution by her treating physician, where the successful endoscopic extraction of the toothbrush was performed 36 hours after it was swallowed. The procedure was carried out with the patient under sedation and by experts in digestive extraction who used an overtube, foreign body forceps, and polypectomy loops. Conclusion: Cases of toothbrush swallowing are rarely reported and occur mainly in people with mental illnesses, such as eating disorders involving self-induced vomiting. Therefore, in these cases, physicians should always believe what these patients say, even in the absence of symptoms and imaging findings, as this enables their timely referral to a digestive service to confirm whether the toothbrush was swallowed or not and to perform the endoscopic extraction as soon as possible, since it can cause serious complications due to its characteristics.

Resumen Introducción. La ingesta de cepillos de dientes, voluntaria o accidental, es una situación poco frecuente que requiere ser tratada como una emergencia, pues por su longitud y dureza, no se espera que estos cuerpos extraños tengan un tránsito completo por el tracto digestivo, lo que puede causar graves complicaciones. Presentación del caso. Mujer de 22 años con trastorno alimentario (bulimia nerviosa) quien al inducirse vomito ingirió involuntariamente un cepillo de dientes. Lamentablemente, después de la valoración inicial en el servicio de urgencias, debido a que no presentaba síntomas, a su antecedente psiquiátrico y a la no identificación del cepillo en estudios de imagen, fue dada de alta. Ante la insistencia de la paciente de decir la verdad, fue remitida por su médico tratante a una institución de salud de segundo nivel, donde, a las 36 horas de la ingesta, se realizó la extracción endoscópica exitosa del cepillo. El procedimiento fue realizado bajo sedación por expertos en extracción digestiva usando un sobretubo, pinzas para cuerpos extraños y asas de polipectomía. Conclusión. Los casos de ingesta de cepillos de dientes son raramente reportados y ocurren principalmente en personas con trastornos psiquiátricos como desórdenes alimentarios que involucran la inducción de vómito. Por tanto, en estos casos siempre se debe creer la versión del paciente, incluso en ausencia de síntomas y hallazgos imagenológicos, pues esto posibilita una remisión oportuna al servicio digestivo para confirmar la ingesta y realizar la extracción endoscópica lo más pronto posible, ya que, por sus características, pueden causar graves complicaciones.

Validação da pontuação Rockall no sangramento do trato gastrointestinal superior em um hospital terciário colombiano / Validation of the rockall score in upper gastrointestinal tract bleeding in a colombian tertiary hospital

ABSTRACT Background Rockall score is the most widely used prognostic scale for assessing risk of complications from non-varicose upper gastrointestinal bleeding (UGIB). Several studies have been conducted in adult populations with non-varicose UGIB in different parts of the world, with conflicting findings regarding the extent of association between the score and some morbidity and mortality outcomes. Also, there is controversy regarding the best cut-off point for the score. Moreover, no studies validating this score in Colombia have been carried out. Objective To assess the diagnostic performance of the Rockall score in predicting rebleeding and mortality in patients with non-varicose UGIB. Methods A prospective cohort study was conducted in patients requiring upper gastrointestinal endoscopy (UGIE) for non-varicose bleeding. The pre-and post-endoscopy Rockall scores were calculated and outcomes, including mortality, UGIB-associated mortality and in hospital rebleeding were determined at the 1 and 3-month time points. The association between the scores and these outcomes was assessed using the chi2 or the Fisher test, whereas the discrimination ability of the score was determined using the areas under the ROC curve (AUC). High discrimination ability was considered to exist in cases in which an AUC ≤0.7 with α=0.05 could be rejected. Results Overall, 177 patients were analyzed. In-hospital outcomes at 1 and 3 months were 12%, 17% and 23% for general mortality, 6%, 12% and 15% for UGIB mortality, and 19%, 30% and 37% for rebleeding. The post-endoscopy Rockall score was associated with the three outcomes at the three time points assessed, while the pre-endoscopy score was only associated with general mortality at the three time points, and rebleeding at 1 and 3 months. Regarding discrimination ability, although the AUC was greater than expected by randomness (0.5) in all cases, only one AUC ≤0.7 was rejected in the post-endoscopy score for in-hospital UGIB mortality (AUC=0.901; 95%CI: 0.845—0.958), at 1 month (AUC=0.836; 95%CI: 0.717—0.954) and at 3 months (AUC=0.869; 95%CI: 0.771—0.967), and for rebleeding at 1 month (AUC=0.793; 95%CI: 0.725—0.861) and at 3 months (AUC=0.806; 95%CI: 0.741—0.871). Conclusion An association was found between the Rockall score and rebleeding and mortality in patients with non-varicose UGIB. Only the post-endoscopy score had a high predictive ability for rebleeding and UGIB mortality.

RESUMO Contexto O escore de Rockall é a escala de prognóstico mais amplamente usada para avaliar o risco de complicações de sangramento gastrointestinal superior não varicoso. Vários estudos foram conduzidos em populações adultas com sangramento gastrointestinal superior não varicoso em diferentes partes do mundo, com achados conflitantes quanto à extensão da associação entre o escore e alguns desfechos de morbimortalidade. Há também controvérsias em relação ao melhor ponto de corte para a pontuação. Além disso, não foram realizados estudos que validem essa pontuação na Colômbia. Objetivo Avaliar o desempenho diagnóstico do escore de Rockall na previsão de ressangramento e mortalidade em pacientes com sangramento gastrointestinal superior não varicoso. Métodos Um estudo de coorte prospectivo foi conduzido em pacientes que necessitaram de endoscopia digestiva alta (EDA) para sangramento não varicoso. Os escores de Rockall pré e pós-endoscopia foram calculados e os resultados, incluindo mortalidade, mortalidade associada ao sangramento gastrointestinal superior não varicoso e ressangramento intra-hospitalar foram determinados nos pontos de tempo de 1 e 3 meses. A associação entre os escores e esses desfechos foram avaliados pelo teste de chi2 ou Fisher, enquanto a habilidade de discriminação do escore foi determinada pelas áreas sob a curva ROC (AUC). Alta capacidade de discriminação foi considerada existente nos casos em que uma AUC ≤0,7 com α=0,05 poderia ser rejeitada. Resultados No geral, 177 pacientes foram analizados. Os desfechos hospitalares em 1 e 3 meses foram de 12%, 17% e 23% para mortalidade geral, 6%, 12% e 15% para mortalidade com hemorragia digestiva alta e 19%, 30% e 37% para ressangramento. O escore de Rockall pós-endoscopia foi associado aos três desfechos nos três momentos avaliados, enquanto o escore pré-endoscopia foi associado apenas à mortalidade geral nos três momentos, e ressangramento em 1 e 3 meses. Em relação à capacidade de discriminação, embora a AUC fosse maior do que o esperado pela aleatoriedade (0,5) em todos os casos, apenas uma AUC ≤0,7 foi rejeitada no escore pós-endoscopia para mortalidade com hemorragia digestiva alta intra-hospitalar (AUC =0,901; 95%IC: 0,845—0,958), em 1 mês (AUC =0,836; 95%IC 0,717—0,954) e em 3 meses (AUC =0,869; 95%IC: 0,771—0,967), e para ressangramento em 1 mês (AUC =0,793; 95%IC: 0,725—0,861) e aos 3 meses (AUC =0,806; 95%IC: 0,741—0,871). Conclusão Foi encontrada associação entre o escore de Rockall, ressangramento e mortalidade em pacientes com hemorragia digestiva alta não varicosa. Apenas o escore pós-endoscopia teve alta capacidade preditiva para ressangramento e mortalidade por sangramento gastrointestinal superior não varicoso.

Perfusion index: Could this be a new triage tool for upper gastrointestinal system bleeding in the emergency department? A prospective cohort study

ABSTRACT BACKGROUND: Many scoring systems for predicting mortality, rebleeding and transfusion needs among patients with upper gastrointestinal bleeding (UGIB) have been developed. However, no scoring system can predict all these outcomes. OBJECTIVE: To show whether the perfusion index (PI), compared with the Rockall score (RS), helps predict transfusion needs and prognoses among patients presenting with UGIB in emergency departments. In this way, critical patients with transfusion needs can be identified at an early stage. DESIGN AND SETTING: Prospective cohort study in an emergency department in Turkey, conducted between June 2018 and June 2019. METHODS: Patients' demographic parameters, PI, RS, transfusion needs and prognosis were recorded. RESULTS: A total of 219 patients were included. Blood transfusion was performed in 174 patients (79.4%). The PI cutoff value for prediction of the need for blood transfusion was 1.17, and the RS cutoff value was 5. The area under the curve (AUC) value for PI (AUC: 0.772; 95% confidence interval, CI: 0.705-0.838; P < 0.001) was higher than for RS (AUC: 0.648; 95% CI: 0.554-0.741; P = 0.002). 185 patients (84.5%) were discharged, and 34 patients (15.5%) died. The PI cutoff value for predicting mortality was 1.1, and the RS cutoff value was 7. The AUC value for PI (AUC: 0.743; 95% CI: 0.649-0.837; P < 0.001) was higher than for RS (AUC: 0.725; 95% CI: 0.639-0.811; P < 0.001). CONCLUSION: PI values for patients admitted to emergency departments with UGIB on admission can help predict their need for transfusion and mortality risk.

Tratamiento quirúrgico de la hemorragia digestiva alta por enfermedad de Dieulafoy / Surgical treatment of upper gastrointestinal bleeding dueto Dieulafoy disease

La enfermedad de Dieulafoy constituye menos del 2 % de las causas de hemorragia digestiva alta. Corresponde a la presencia de un vaso sanguíneo arterial de trayecto tortuoso, que protruye a través de un defecto mucoso localizado, generalmente, proximal en el estómago. Se presenta como una hematemesis masiva, a veces recu-rrente, con inestabilidad hemodinámica. La endoscopia es el método diagnóstico y terapéutico de elección. Si esta fracasa, está indicado practicar una angiografía selectiva que permita identificar el punto sangrante y producir un embolismo. En algunas ocasiones, ninguna de estas dos técnicas consigue detener la hemorragia, en cuyo caso está indicada una cirugía urgente. Se deben practicar resecciones gástricas limitadas (gastrectomías en cuña o tubulares) a la zona sangrante localizada mediante las pruebas anteriores; así, se evitan grandes gastrectomías que implican la práctica de anastomosis por el gran riesgo de dehiscencia que estas últimas cuando hay inestabilidad hemodinámica.Se presenta el caso de un paciente con hemorragia digestiva alta secundaria a enfermedad de Dieulafoy, que precisó intervención quirúrgica urgente por la imposibilidad de resolver el sangrado mediante endoscopia. Se describen el diagnóstico y el tratamiento de la enfermedad de Dieulafoy como causa de hemorragia digestiva alta en el adulto, y se presenta una revisión de la literatura científica

Dieulafoy's disease constitutes less than 2% of the causes of upper gastrointestinal bleeding. It corresponds to the presence of a tortuous arterial blood vessel which protrudes through a localized mucosal defect, usually proximal in the stomach. It presents as a massive hematemesis, sometimes recurrent, with hemodynamic instability.Endoscopy is the diagnostic and therapeutic method of choice. If this fails, it is indicated to perform a selective angiography to identify the bleeding point and embolize it. In some cases, none of these two techniques manages to stop the bleeding, in which case urgent surgery is indicated. Limited gastric resections (wedge or tubular gastrectomies) should be performed to the bleeding area, thus avoiding large gastrectomies that involve anastomosis due to the high leak risk they have in hemodynamically unstable patients.We present the case of a patient with upper gastrointestinal bleeding secondary to Dieulafoy's disease, who required urgent surgical intervention due to the impossibility of resolving the bleeding endoscopically. The diagnosis and treatment of Dieulafoy's disease as a cause of upper gastrointestinal bleeding in adults are described and a review of the scientific literature is presented

Utilidade clínica dos escores de risco no sangramento varicoso / Clinical utility of risk scores in variceal bleeding

ABSTRACT BACKGROUND: Variceal bleeding remains important cause of upper gastrointestinal bleed. Various risk scores are used in risk stratification for non-variceal bleed. Their utility in variceal bleeding patients is not clear. This study aims to compare probability of these scores in predicting various outcomes in same population. OBJECTIVE: This study aims to compare probability of these scores in predicting various outcomes in same population. To study characteristics and validate AIMS65, Rockall, Glasgow Blatchford score(GBS), Progetto Nazionale Emorragia Digestiva (PNED) score in variceal Upper Gastrointestinal Bleed (UGIB) patients for predicting various outcomes in our population. METHODS: Three hundred subjects with UGIB were screened prospectively. Of these 141 patients with variceal bleeding were assessed with clinical, blood investigations and endoscopy and risk scores were calculated and compared to non-variceal cases. All cases were followed up for 30 days for mortality, rebleeding, requirement of blood transfusion and need of radiological or surgical intervention. RESULTS: Variceal bleeding (141) was more common than non variceal (134) and 25 had negative endoscopy. In variceal group, cirrhosis (85%) was most common etiology. Distribution of age and sex were similar in both groups. Presence of coffee coloured vomitus (P=0.002), painless bleed (P=0.001), edema (P=0.001), ascites (P=0.001), hemoglobin <7.5 gms (P<0.001), pH<7.35 (P<0.001), serum bicarbonate level <17.6 mmol/L (P<0.001), serum albumin<2.75 gms% (P<0.001), platelet count <1.2 lacs/µL (P<0.001), high INR 1.35 (P<0.001), BUN >25mmol/L (P<0.001), and ASA status (P<0.001), high lactate >2.85 mmol/L (P=0.001) were significant. However, no factor was found significant on multivariate analysis. Rockall was found to be significant in predicting mortality and rebleed. AIMS65 was also significant in predicting mortality. GBS was significant in predicting blood transfusion and need of intervention. PNED score was significant in all events except mortality. CONCLUSION: All four scores had lower predictive potential in predicting events in variceal bleed. However, AIMS65 & Rockall score were significant in predicting mortality, while GBS in predicting need of transfusion and intervention. PNED score was significant in all events except mortality.

RESUMO CONTEXTO: O sangramento varicoso permanece como importante causa de sangramento gastrointestinal superior. Vários escores são utilizados na estratificação do risco para sangramento não varicoso. Sua utilidade em pacientes de sangramento varicoso não é clara. OBJETIVO: Este estudo tem como objetivo comparar a probabilidade desses escores em prever vários desfechos na mesma população. Estudar característica e validar o AIMS65, o Rockall, a Pontuação de Glasgow Blatchford (GBS), o escore Progetto Nazionale Emorragia Digestiva (PNED), na pontuação em hemorragia gastrointestinal varicosa superior (UGIB) em pacientes para prever vários resultados em nossa população. MÉTODOS: Um total de 300 indivíduos com UGIB foram rastreados prospectivamente. Destes, 141 pacientes com sangramento varicoso foram submetidos à avaliação clínica, hematológica e endoscopia tendo seus escores de risco calculados e comparados aos casos não-varicosos. Todos os casos foram acompanhados por 30 dias para mortalidade, necessidade de transfusão sanguínea por ressangramento ou de necessidade de intervenção radiológica ou cirúrgica. RESULTADOS: O sangramento varicoso (141) foi mais comum do que não varicoso (134) e em 25 teve endoscopia negativa. No grupo varicoso, a cirrose foi a etiologia mais comum (85%). A distribuição da idade e do sexo foi semelhante em ambos os grupos. Presença de vômito colorido em borra de café (P=0,002), sangramento indolor (P=0,001), edema (P=0,001), ascite (P=0,001), hemoglobina <7,5 GMS (P<0,001), pH <7,35 (P<0,001), nível de bicarbonato sérico <17,6 mmol/L (P<0,001), albumina sérica <2,75 GMS% (P<0,001), contagem plaquetária <1,2 Lacs/μL (P<0,001), INR elevada 1,35 (P<0,001), Bun >25 mmol/L (P<0,001) e estado ASA (P<0,001), lactato elevado >2,85 mmol/L (P=0,001) foram significativos. Entretanto, nenhum fator foi encontrado como significativo na análise multivariada. Rockall foi significativo em prever a mortalidade e ressangrar. O AIMS65 também foi significante na predição da mortalidade. O GBS foi significativo na predição de transfusão sanguínea e necessidade de intervenção. O escore de PNED foi significante em todos os eventos, exceto mortalidade. CONCLUSÃO: Todos os quatro escores apresentaram menor potencial preditivo na predição de eventos em sangramento varicoso. Entretanto, o AIMS65 e o escore de Rockall foram significantes na predição da mortalidade, enquanto o GBS na predição da necessidade de transfusão e intervenção. O escore de PNED foi significante em todos os eventos, exceto mortalidade.

Upper Gastrointestinal Tract Endoscopic Biopsies

Introduction: Upper GI Upper gastrointestinal tract is an important site for wide variety of lesions especially malignant tumors. Endoscopy in combination with endoscopic biopsy plays an important role in the diagnosis of upper gastrointestinal tract neoplasms and therefore aids in their early management. Aims and objective: This study was done to determine thehistopathologic spectrum of Upper Gastrointestinal Tract Mucosal Biopsies.Materials and methods: A prospective study of upper GI endoscopic biopsy was carried out in a tertiary care hospital over a span of one year.55 biopsysamples were subjected to histopathological examination. Results:: Among the 55 endoscopic biopsies- Oesophageal biopsies were 25 (45.45%), gastric biopsies were 18(32.7%) and duodenal biopsies were 12 (21.8%). Out of 55 cases, 35 (63.63%) were males and 20 (36.36%) were females with a male to female ratio of 1.75:1. Biopsies comprised of 42 (76.3%)non neoplastic cases and 13(23.6%) neoplastic cases. Among the 13 neoplastic cases,08 cases were from oesophagus and 05 cases from stomach. All the 08 esophageal malignancies were squamous cell carcinoma and all the 05 gastric malignancies were adenocarcinoma.Conclusion: We conclude that Histopathological analysis of gastrointestinal lesions aids the clinicians for follow up and specific treatment and provides a powerful diagnostic tool for better patient management.

The Role of Gut Microbiota and Use of Probiotics in the Treatment of Upper Gastrointestinal Diseases

Gut microbiota have been known to play an essential role in host immunity and metabolism. Dysbiosis is associated with various gastrointestinal (GI) and other diseases such as cancers, metabolic diseases, allergies, and immunological disorders. So far, the role of gut microbiota has been studied mainly in lower GI disease but has recently been reported in upper GI diseases other than Helicobacter pylori infection, including Barrett's esophagus, esophageal carcinoma, gastric cancer, functional dyspepsia, and non-steroidal anti-inflammatory drug-induced small intestinal mucosal injury. Probiotics have some beneficial effect on these diseases, but the effects are strain specific.

The value of ultrasound in diagnosis of neonatal upper and lower gastrointestinal perforation / 中国小儿急救医学

Objective@#To explore the value of ultrasound in the differential diagnosis of neonatal upper and lower gastrointestinal tract(GIT)perforation.@*Methods@#We retrospectively reviewed the ultrasound findings of 42 neonates of surgery-confirmed neonatal GIT perforation in our hospital from January 1, 2015 to December 31, 2018.The accuracy of ultrasound for detecting GIT perforation and the ultrasound features of upper and lower GIT perforation were evaluated.@*Results@#(1)Of the 42 neonates with GIT perforation, 1 case didn′t undergo ultrasound, 2 cases were missed, and 1 case was misdiagnosed.Thirty-eight neonates were diagnosed of GIT perforation by ultrasound preoperatively, with a detection rate of 92.7%(38/41). The locations of GIT perforation were identified by ultrasound in 30 cases(78.9%, 30/38), including 11 cases of upper GIT perforation and 19 cases of lower GIT perforation.(2)A common sonographic finding of GIT perforation in 38 cases was pneumoperitoneum, which appeared as an echogenic line with posterior reverberation artifact under diaphragm or anterior to hepatic/splenic surface and a "stratosphere" sign in M-mode sonography.Free gas changed position when the patient′s position was changed, and didn′t change due to respiratory change.Besides, free gas dispersed with compression on abdomen, and gathered without compression.(3)Upper GIT perforation was showed that poor filling of the stomach cavity, and the abdominal free gas sharply increased.Lower GIT perforation was characterized by collapsed bowel, blurred and interrupted intestinal wall structure, and more accompanied with intestinal obstruction.(4)There was no significant difference of detection rate between ultrasound and X-ray in diagnosing GIT perforation[92.7%(38/41)vs.83.3%(35/42)](P>0.05), whereas ultrasound more sensitive for a very small amount of free gas in the early stage of perforation.(5)Helicobacter pylori infection was found in two cases of GIT perforation.@*Conclusion@#Ultrasound can be used for differential diagnosis of upper and lower GIT perforation, and could be recommended as the first choice for detecting GIT perforation in neonatal patients.

The value of ultrasound in diagnosis of neonatal upper and lower gastrointestinal perforation / 中国小儿急救医学

Objective To explore the value of ultrasound in the differential diagnosis of neonatal upper and lower gastrointestinal tract ( GIT) perforation. Methods We retrospectively reviewed the ultra-sound findings of 42 neonates of surgery-confirmed neonatal GIT perforation in our hospital from January 1, 2015 to December 31,2018. The accuracy of ultrasound for detecting GIT perforation and the ultrasound fea-tures of upper and lower GIT perforation were evaluated. Results (1)Of the 42 neonates with GIT perfora-tion,1 case didn′t undergo ultrasound,2 cases were missed,and 1 case was misdiagnosed. Thirty-eight neo-nates were diagnosed of GIT perforation by ultrasound preoperatively,with a detection rate of 92. 7%(38/41). The locations of GIT perforation were identified by ultrasound in 30 cases(78. 9%,30/38),including 11 cases of upper GIT perforation and 19 cases of lower GIT perforation. (2)A common sonographic finding of GIT perforation in 38 cases was pneumoperitoneum,which appeared as an echogenic line with posterior rever-beration artifact under diaphragm or anterior to hepatic/splenic surface and a "stratosphere" sign in M-mode sonography. Free gas changed position when the patient′s position was changed,and didn′t change due to re-spiratory change. Besides,free gas dispersed with compression on abdomen,and gathered without compres-sion. (3)Upper GIT perforation was showed that poor filling of the stomach cavity,and the abdominal free gas sharply increased. Lower GIT perforation was characterized by collapsed bowel,blurred and interrupted intestinal wall structure, and more accompanied with intestinal obstruction. ( 4 ) There was no significant difference of detection rate between ultrasound and X-ray in diagnosing GIT perforation [92. 7%(38/41) vs. 83. 3%(35/42)]( P>0. 05),whereas ultrasound more sensitive for a very small amount of free gas in the early stage of perforation. (5) Helicobacter pylori infection was found in two cases of GIT perforation. Conclusion Ultrasound can be used for differential diagnosis of upper and lower GIT perforation,and could be recommended as the first choice for detecting GIT perforation in neonatal patients.

Disminución en la frecuencia de infección por Helicobacter pylori en endoscopías digestivas altas / Helicobacter pylori infection detected during upper gastrointestinal endoscopy

Background: Helicobacter pylori (HP) is the most widespread chronic human infection worldwide and the most important pathogenic factor of gastric cancer. The calculated prevalence at the Clinical Hospital of the University of Chile from 2002 to 2005 was 44.9%. Aim: To determine the current prevalence of HP in patients undergoing an upper gastrointestinal endoscopy (UGI) and analyze its distribution according to age and endoscopic findings. Material and Methods: We reviewed 3.433 UGI performed during the year 2015, selecting those in which rapid urease test (RUT) was done. A positive RUT or a positive gastric biopsy (GB) were considered as HP infection. Results: RUT was done in 1862 UGI (55%) performed in patients aged 51 ± 17 years, (66% women). In 23% of these endoscopies, the RUT was positive. A GB was obtained 43% of endoscopies and 30% were positive for HP. In 105 patients the RUT was negative and the GB positive (rendering a 19.5% false negative rate). HP was detected by RUT and GB in 29% of endoscopies. The highest prevalence of infection (38.1%) was found between 40 and 49 years. HP infection had odds ratio of 4.24 for nodular gastropathy, 2.63 for gastric ulcer and 2.14 for duodenal ulcer (p < 0.05). Conclusions: HP prevalence in our center decreased significantly from 44.9% to 28.9% in 11 years. False negative RUT results may bias this finding. The use of proton pump inhibitors and antimicrobials that can interfere with the detection of HP should be registered to properly analyze the results of the RUT.

Results The date pits were the most common type of foreign bodies and upper esophagus were the most common locations in upper gastrointestinal tract; In Logistic regression analysis, risk factors for complications were the duration of impaction that longer than 12 hours (OR

Endoscopy and clinicopathological characteristics of upper gastrointestinal tract metastasis / 中国内镜杂志

Objective To explore the endoscopic and clinicopathological characteristics of upper gastrointestinal tract metastasis,it can improve the diagnosibility of endoscopists and pathologists. Methods Three cases of upper gastrointestinal tract metastasis and seven cases in the related literature were studied, and its endoscopy and clinicopathological findings were analyzed with a review of the literature, whose gastrointestinal symptoms were the first manifestation. Results Case 1 endoscopic detection of esophageal ulcer lesions, pathological diagnosis of metastatic cancer, considering the source of the lung, confirmed by imaging examination; Case 2 showed that the gastric body was prominent, and the pathological diagnosis was squamous cell carcinoma. It was suggested that the clinical examination should be carried out without metastasis, and then confirmed by imaging examination and bronchoscopy biopsy; Case 3 endoscopic examination revealed multiple polypoid lesions in the stomach and duodenum, and was pathologically diagnosed as metastatic renal cell carcinoma. 3 patients were correctly diagnosed, thus avoiding unnecessary radical surgical treatment. 7 cases of patients in the literature were aged, they were also in a variety of gastrointestinal symptoms and the first diagnosis, no previous history of cancer, endoscopic lesions in the stomach or duodenum, supplemented by immunohistochemical staining in pathological diagnosis were diagnosed as metastases, the primary tumor site without organ specific. Conclusion The metastasis of upper gastrointestinal tract is rare, especially when the gastrointestinal symptoms were the first manifestation,it is usually missed and misdiagnosed. The diagnosis relies on the endoscopic and pathological examination, supplemented by the imaging examination, so the patients could get effective treatment in time.

Characteristics of Upper Gastrointestinal Tract Involvement in Korean Pediatric Crohn's Disease: A Multicenter Study / 대한소아소화기영양학회지

PURPOSE: Crohn's disease (CD) can involve any site of the gastrointestinal tract (GIT). However, the characteristics of upper GIT involvement in CD are unclear, especially in the Eastern pediatric population. This study aimed to estimate the prevalence of upper GIT involvement and identify the clinical features of Korean children with CD. METHODS: This was a retrospective multicenter cohort study that included 52 pediatric patients with CD who underwent esophagogastroduodenoscopy and biopsy. The clinical symptoms and endoscopic and histologic features of the upper GIT were identified according to the presence or absence of upper gastrointestinal symptoms. RESULTS: Among the 52 patients, upper GIT involvement was noted in 50.0% (26/52). The mean age at CD diagnosis was 14.1±2.1 years. Gastric ulcer was the most common lesion (19.2%) found on upper GIT endoscopy, followed by duodenal ulcers (15.4%). Chronic inflammation was the most common histopathologic feature (75.0%), followed by gastric erosion (17.3%). Granuloma was found in 9.6% of patients. Helicobacter pylori infection was identified in 5.8% of patients. Endoscopic and histologic findings were not significantly different, but the mean values of erythrocyte sedimentation rate (60.7±27.1 vs. 43.0±27.6 mm/h, p=0.037) and C-reactive protein (16.5±28.2 vs. 6.62±13.4 mg/dL, p=0.014) were significantly different between patients with and without upper gastrointestinal CD symptoms. CONCLUSION: Upper GIT involvement was relatively common in pediatric patients with CD irrespective of upper gastrointestinal symptoms, and H. pylori infection was relatively uncommon. The results of this study should aid the establishment of regional guidelines for upper GIT examination.
