Necrosis esofágica aguda (esófago negro) asociado a neoplasias digestivas / Acute esophageal necrosis (black esophagus) associated with digestive neoplasms

INTRODUCCIÓN. La necrosis esofágica aguda es un síndrome raro que se caracteriza endoscópicamente por una apariencia negra circunferencial irregular o difusa de la mucosa esofágica intratorácica, la afectación es generalmente del esófago distal y la transición abrupta de mucosa normal en la unión gastroesofágica, con extensión proximal variable. CASOS. Se presentan dos casos con diferentes comorbiliades, presentación de signos y síntomas, antecedentes y tratamiento, teniendo en común el diagnóstico a través de endoscopía digestiva alta. RESULTADOS. Caso clínico 1: tratamiento clínico basado en hidratación, suspensión de vía oral, omeprazol intravenoso y sucralfato; mala evolución clínica caracterizada por: disfagia, intolerancia oral y recurrencia del sangrado digestivo alto, se realiza colocación de gastrostomía endoscópica. Caso clínico 2: esófago con mucosa con fibrina y parches de necrosis extensa, se realiza compensación tanto de foco infeccioso pulmonar como hidratación y nutrición, en estudios complementarios se observa masa colónica, con estudio histopatológico confirmatorio de adenocarcinoma de colon en estado avanzado. DISCUSIÓN. La esofagitis necrotizante aguda es una entidad inusual, de baja prevalencia e incidencia, asociada con estados de hipoperfusión sistémica y múltiples comorbilidades que favorezcan un sustrato isquémico. Al revisar los reportes de casos que hay en la literatura médica, los casos que reportamos se correlaciona con las características clínicas, epidemiológicas, endoscópicas y factores de riesgo causales de la enfermedad. La presentación clínica más frecuente es el sangrado digestivo alto, que se debe correlacionar con el hallazgo endoscópico clásico. Nuestro primer caso reportado termina con la colocación de una gastrostomía para poder alimentarse. CONCLUSIÓN. El pronóstico de la necrosis esofágica aguda es malo y se requiere un alto índice de sospecha clínica y conocimiento de esta infrecuente patología para un diagnóstico temprano y un manejo oportuno. Se requiere una evaluación por endoscopia digestiva alta. Es una causa de sangrado gastrointestinal que conlleva tasas altas de mortalidad, principalmente en adultos mayores frágiles. El reconocimiento temprano y la reanimación agresiva son los principios fundamentales para un mejor resultado de la enfermedad.

INTRODUCTION. Acute esophageal necrosis is a rare syndrome that is characterized endoscopically by an irregular or diffuse circumferential black appearance of the intrathoracic esophageal mucosa, the involvement is generally of the distal esophagus and the abrupt transition of normal mucosa at the gastroesophageal junction, with variable proximal extension. CASES. Two cases are presented with different comorbidities, presentation of signs and symptoms, history and treatment, having in common the diagnosis through upper gastrointestinal endoscopy. RESULTS. Clinical case 1: clinical treatment based on hydration, oral suspension, intravenous omeprazole and sucralfate; poor clinical evolution characterized by: dysphagia, oral intolerance and recurrence of upper digestive bleeding, endoscopic gastrostomy placement was performed. Clinical case 2: esophagus with mucosa with fibrin and patches of extensive necrosis, compensation of both the pulmonary infectious focus and hydration and nutrition is performed, in complementary studies a colonic mass is observed, with a confirmatory histopathological study of colon adenocarcinoma in an advanced state. DISCUSSION. Acute necrotizing esophagitis is an unusual entity, with low prevalence and incidence, associated with states of systemic hypoperfusion and multiple comorbidities that favor an ischemic substrate. When reviewing the case reports in the medical literature, the cases we report correlate with the clinical, epidemiological, endoscopic characteristics and causal risk factors of the disease. The most common clinical presentation is upper gastrointestinal bleeding, which must be correlated with the classic endoscopic finding. Our first reported case ends with the placement of a gastrostomy to be able to feed. CONCLUSION. The prognosis of acute esophageal necrosis is poor and a high index of clinical suspicion and knowledge of this rare pathology is required for early diagnosis and timely management. Evaluation by upper gastrointestinal endoscopy is required. It is a cause of gastrointestinal bleeding that carries high mortality rates, mainly in frail older adults. Early recognition and aggressive resuscitation are the fundamental principles for a better outcome of the disease.

Serie de casos de sangrado intraluminal postoperatorio en colectomía izquierda / Case series of postoperative intraluminal bleeding in left colectomy

Introducción: El sangrado digestivo intraluminal postoperatorio es una entidad poco frecuente y su manifestación clínica no difiere de la hemorragia digestiva baja de otra etiología. A pesar de que su presentación más habitual es la hematoquecia autolimitada en la primera deposición, en un discreto porcentaje puede requerir transfusiones, tratamiento endoscópico, hemodinámico, o incluso cirugía. Objetivo: Analizar los pacientes con sangrado digestivo intraluminal postoperatorio tratados en un centro de alta complejidad y realizar una revisión bibliográfica del tema. Diseño: Estudio retrospectivo, descriptivo. Material y métodos: Pacientes con sangrado anastomótico durante el post operatorio inmediato de una colectomía izquierda, operados en el Servicio de Cirugía General y Coloproctología desde enero del 2017 a diciembre del 2021. Las variables estudiadas fueron edad, sexo, anticoagulación y su causa, descenso de hemoglobina, cirugía realizada y su indicación, vía de abordaje, configuración de la anastomosis, electividad de la cirugía, complicaciones, días de internación y manejo terapéutico. Resultados: Se incluyeron 4 pacientes con una edad media de 72 (rango 54-87) años y una distribución por sexo de 1:1. En todos la colectomía izquierda fue programada y en 3 el abordaje fue laparoscópico. La anastomosis fue termino-terminal con sutura mecánica circular. Todos los pacientes presentaron sangrado en las primeras 24 horas postoperatorias. El tratamiento fue decidido de acuerdo a la condición hemodinámica: en los 2 pacientes con estabilidad hemodinámica fue suficiente el tratamiento conservador con reanimación y transfusiones. Los otros 2 que presentaron inestabilidad hemodinámica requirieron manejo intervencionista con endoscopía rígida, videocolonoscopía y cirugía. Conclusión: El sangrado intraluminal es una complicación poco frecuente de la anastomosis colorrectal que requiere manejo intervencionista solo en los pacientes que presentan inestabilidad hemodinámica. (AU)

Introduction: Postoperative intraluminal gastrointestinal bleeding is a rare entity and its clinical manifestation does not differ from lower gastro-intestinal bleeding of another etiology. Despite the fact that its most common presentation is self-limited hematochezia at the first stool, in a small percentage it may require transfusions, endoscopic or hemodynamic management, or even surgery. Aim: To analyze the patients with postoperative intraluminal gastrointestinal bleeding treated in a tertiary center and to carry out a bibliographic review of the subject. Design: Retrospective descriptive study. Material and methods: Patients with immediate postoperative anastomotic bleeding from a left colectomy, operated on at the General Surgery and Coloproctology Service from January 2017 to December 2021 were included. The variables recorded were age, sex, anticoagulation and its cause, decrease in hemoglobin, procedure performed and its indication, surgical approach, type of anastomosis, electiveness of surgery, complications, hospital stay and management. Results: Four patients with a mean age of 72 (range 54-87) years and a 1:1 gender distribution were included. All procedures were elective and 3 laparoscopic. All anastomoses were performed end-to-end with a circular stapler. All patients presented bleeding in the first 24 postoperative hours. The treatment was decided according to the hemodynamic condition; patients with hemodynamic stability (2) received medical treatment while those with hemodynamic instability (2) required interventional management with rigid endoscopy, colonoscopy and surgery. Conclusion: Intraluminal bleeding is a rare complication of colorectal anastomosis that requires interventional management only in patients with hemodynamic instability. (AU)

Introducción: Existen varios sistemas de puntuación para predecir los resultados adversos en los pacientes con hemorragia digestiva alta no varicosa, pero no se han validado lo suficiente y cada uno pertenece a distintas poblaciones fuentes. Objetivo: Demostrar la utilidad de una escala propuesta para predecir las probabilidades de resangrado, de mortalidad y de necesidad de cirugía en los pacientes con hemorragia digestiva alta no varicosa. Métodos: Se realizó un estudio retrospectivo de una prueba diagnóstica en el hospital de Prenda, Luanda, Angola desde enero del 2021 hasta mayo del 2022. El universo estuvo formado por 93 pacientes atendidos durante ese período con el criterio de inclusión de tener el diagnóstico de hemorragia digestiva alta de origen no varicoso. Resultados: De un total de 93 pacientes se obtuvo como desenlace primario una recurrencia del sangrado de 18 pacientes para un 19,35 por ciento del total, seguido con 12 fallecidos para un 12,90 por ciento del total y cuatro fallecidos para un 4,40 por ciento del total. Los valores predictivos de la escala de forma general fueron, al ser aplicada una sensibilidad de 0,91, la especificidad de un 0,92, el valor predictivo negativo de un 0,95 y el valor predictivo negativo de un 0,86. Conclusiones: La escala propuesta tiene una sensibilidad y especificidad adecuada para predecir, en los pacientes con hemorragia digestiva alta no varicosa, la probabilidad de resangrado, de mortalidad y la necesidad de cirugía(AU)

Introduction: Several scoring systems exist to predict adverse outcomes in patients with nonvariceal upper gastrointestinal bleeding, but they have not been sufficiently validated and each pertains to different source populations. Objective: To demonstrate the usefulness of a proposed scoring scale to predict the probability of rebleeding, mortality, and need for surgery in patients with nonvariceal upper gastrointestinal bleeding. Methods: A retrospective study of a diagnostic test was performed at the hospital of Prenda, Luanda, Angola, from January 2021 to May 2022. The study universe consisted of 93 patients attended during that period, with the inclusion criterion of having a diagnosis of upper gastrointestinal bleeding of nonvariceal origin. Results: From a total of 93 patients, the primary outcome was a recurrence of bleeding in 18 patients, accounting for 19.35 percent of the total; followed by 12 deaths, representing 12.90 percent of the total, and four deaths, accounting for 4.40 percent of the total. After the scale was applied, the following general predictive values were obtained: sensitivity of 0.91, specificity of 0.92, negative predictive value of 0.95 and negative predictive value of 0.86. Conclusions: The proposed scale presents adequate sensitivity and specificity for predicting the probability of fatal rebleeding and the need for surgery in patients with nonvariceal upper gastrointestinal bleeding(AU)

Angiosarcoma gastrointestinal multifocal, con compromiso extenso de estómago, intestino delgado y colon. Reporte de un caso / Multifocal gastrointestinal angiosarcoma, with extensive gastric, small intestine and colon involvement. A case report

Introducción. El angiosarcoma es una neoplasia vascular originada a nivel del endotelio, de baja frecuencia, conocido por su agresividad y crecimiento acelerado. Alcanza solo el 1 al 2 % del total de los sarcomas. La presentación gastrointestinal es infrecuente y su incidencia es poco conocida debido al escaso reporte de casos en la literatura. Suele identificarse en etapas avanzadas debido a la dificultad del diagnóstico histopatológico por sus características morfológicas, siendo necesario aplicar tinciones especiales o estudio inmunohistoquímico. Caso clínico. Por su interés y singularidad, presentamos el caso de un paciente masculino de 54 años, quien consultó con hemorragia digestiva profusa, anemización y requerimiento de terapia transfusional. Resultados. Durante el proceso diagnóstico, en la endoscopia encontraron diversas lesiones multifocales que se extendían por gran parte del tracto gastrointestinal. El estudio histopatológico mostró angiosarcoma gastrointestinal. Discusión. El angiosarcoma del tracto gastrointestinal es extremadamente infrecuente, de difícil diagnóstico y bajas posibilidades de manejo curativo, con opciones terapéuticas limitadas, lo que configura un mal pronóstico a corto plazo

Introduction. Angiosarcoma is a vascular neoplasm originating from endothelial cells, known for its aggressiveness, accelerated growth and reduced frequency. Reach only 1 to 2% of total sarcomas. Gastrointestinal presentation is extremely rare, the true incidence is poorly known, due to the limited reports of this entity in the literature. It is usually identified in advanced stages in view of the difficulty of the histopathological diagnosis, attributable to its morphological characteristics, being necessary to apply special stains or immunohistochemical study. Case report. Due to their interest and uniqueness, we present the case of a 54-year-old male patient, who presented with a profuse gastrointestinal bleeding, anemia, and requirement for transfusion therapy. Results. The endoscopy detected several multifocal lesions that extended most of the gastrointestinal tract. The histopathological study showed gastrointestinal angiosarcoma. Discussion. Angiosarcoma of the gastrointestinal tract is extremely uncommon, difficult to diagnose and has low possibilities of curative management, with limited therapeutic options, which configures a poor prognosis in the short term

Recompensation of complications in patients with hepatitis B virus-related decompensated cirrhosis treated with entecavir antiviral therapy / 中华肝脏病杂志

Objective: To analyze the occurrence of recompensation conditions in patients with chronic hepatitis B virus-related decompensated cirrhosis after entecavir antiviral therapy. Methods: Patients with hepatitis B virus-related decompensated cirrhosis with ascites as the initial manifestation were prospectively enrolled. Patients who received entecavir treatment for 120 weeks and were followed up every 24 weeks (including clinical endpoint events, hematological and imaging indicators, and others) were calculated for recompensation rates according to the Baveno VII criteria. Measurement data were compared using the Student t-test or Mann-Whitney U test between groups. Categorical data were compared by the χ (2) test or Fisher's exact probability method between groups. Results: 283 of the 320 enrolled cases completed the 120-week follow-up, and 92.2% (261/283) achieved a virological response (HBV DNA 20 IU/ml). Child-Pugh and MELD scores were significantly improved after treatment (8.33 ± 1.90 vs. 5.77 ± 1.37, t = 12.70, P < 0.001; 13.37 ± 4.44 vs. 10.45 ± 4.58, t = 5.963, P < 0.001). During the 120-week follow-up period, 14 cases died, two received liver transplants, 19 developed hepatocellular cancer, 11 developed gastroesophageal variceal bleeding, and four developed hepatic encephalopathy. 60.4% (171/283) (no decompensation events occurred for 12 months) and 56.2% (159/283) (no decompensation events occurred for 12 months and improved liver function) of the patients had achieved clinical recompensation within 120 weeks. Patients with baseline MELD scores > 15 after active antiviral therapy achieved higher recompensation than patients with baseline MELD scores ≤15 [50/74 (67.6%) vs. 109/209 (52.2%), χ (2) = 5.275, P = 0.029]. Conclusion: Antiviral therapy can significantly improve the prognosis of patients with hepatitis B virus-related decompensated cirrhosis. The majority of patients (56.2%) had achieved recompensation. Patients with severe disease did not have a lower probability of recompensation at baseline than other patients.

Factors influencing bilirubin elevation and its correlation with UGT1A1 gene polymorphism in the early postoperative period of transjugular intrahepatic portosystemic shunt / 中华肝脏病杂志

Objective: To investigate the factors influencing total bilirubin elevation and its correlation with UGT1A1 gene polymorphism in the early postoperative period of transjugular intrahepatic portosystemic shunt (TIPS). Methods: 104 cases with portal hypertension and esophageal variceal hemorrhage (EVB) treated with elective TIPS treatment were selected as the study subjects and were divided into a bilirubin-elevated group and a normal bilirubin group according to the total bilirubin elevation level during the early postoperative period. Univariate analysis and logistic regression were used to analyze the factors influencing total bilirubin elevation in the early postoperative period. PCR amplification and first-generation sequencing technology were used to detect the polymorphic loci of the UGT1A1 gene promoter TATA box, enhancer c.-3279 T > G, c.211G > A, and c.686C > A. Logistic regression was used to analyze the correlation of four locus alleles and genotypes with elevated total bilirubin in the early postoperative period. Results: Among the 104 cases, 47 patients were in the bilirubin elevated group, including 35 males (74.5%) and 12 females (25.5%), aged (50.72 ± 12.56) years. There were 57 cases in the normal bilirubin group, including 42 males (73.7%) and 15 females (26.3%), aged (51.63 ± 11.10) years. There was no statistically significant difference in age (t = -0.391, P = 0.697) and gender (χ(2) = 0.008, P = 0.928) between the two groups of patients. Univariate analysis revealed that preoperative alanine transaminase (ALT) level (χ(2) = 5.954, P = 0.015), total bilirubin level (χ(2) = 16.638, P < 0.001), MELD score (χ(2) = 10.054, P = 0.018), Child-Pugh score (χ(2) = 6.844, P = 0.022), and postoperative portal vein branch development (χ(2) = 6.738, P = 0.034) were statistically significantly different between the two groups. Logistic regression analysis showed that preoperative ALT level, total bilirubin level, and portal vein branch development after TIPS were correlated with the elevated total bilirubin in the early postoperative period. The polymorphism of the c.211G > A locus of the UGT1A1 gene correlation had elevated total bilirubin in the early postoperative period of TIPS. The risk of elevated total bilirubin was increased in the population carrying allele A (P = 0.001, OR = 4.049) in the early postoperative period. Allelic polymorphisms in the TATA box promoter region and enhancer c.-3279 T > G and c.686C > A had no statistically significant difference between the bilirubin-elevated group and the normal bilirubin group. Conclusion: The preoperative ALT level, total bilirubin level, and portal vein branch development are correlated with the elevated total bilirubin in early postoperative patients. The polymorphisms of the UGT1A1 gene and enhancer c.211G > A are correlated with the occurrence of elevated total bilirubin in the early postoperative period of TIPS. Allele A carrier may have a higher risk of elevated total bilirubin in the early postoperative period.

Anti-neutrophil cytoplasmic antibody-associated vasculitis with gastrointestinal bleeding as the main symptom: a case report and literature review / 中华危重病急救医学

Anti-neutrophil cytoplasmic antibody-associated vasculitis (AAV) has a wide range of symptoms, and it is difficult for clinicians to make a quick and correct diagnosis. On November 11, 2021, a 36-year-old male patient with AAV was admitted to the emergency and critical care department of Yichang Central People's Hospital. He was admitted to the emergency intensive care unit (EICU) with gastrointestinal symptoms (abdominal pain, black stool) as the main physical signs, and was initially diagnosed as AAV with gastrointestinal hemorrhage (GIH). No bleeding point was found after repeated gastroscopy and colonoscopy. Abdominal emission CT (ECT) showed diffuse hemorrhage in the ileum, ascending colon and transverse colon. Multi-disciplinary consultation in the whole hospital considered the diffuse hemorrhage caused by small vascular lesions in the digestive tract caused by AAV. Pulse therapy with methylprednisolone 1 000 mg/d and immunosuppressive therapy with cyclophosphamide (CTX) 0.2 g/d were administered. The patient's symptoms quickly relieved and transferred out of the EICU. After 17 days of treatment, the patient finally died of massive gastrointestinal bleeding. A systematic review of relevant literatures combined with the case diagnosis and treatment process found that only a minority of AAV patients present with gastrointestinal symptoms as their first symptoms, and patients with GIH were very rare. Such patients had a poor prognosis. This patient delayed the use of induced remission and immunosuppressive agents due to the treatment of gastrointestinal bleeding, which may be the main cause of life-threatening GIH secondary to AAV. Gastrointestinal bleeding is a rare and fatal complication of vasculitis. Timely and effective induction and remission treatment is the key to survival. Whether patients should receive maintenance therapy, the duration of maintenance therapy, and the search for markers of disease diagnosis and treatment response are directions and challenges for further research.

Comparison of aspirin treatment strategies for primary prevention of cardiovascular diseases: A decision-analytic Markov modelling study / 北京大学学报(医学版)

OBJECTIVE@#To compare the expected population impact of benefit and risk of aspirin treatment strategies for the primary prevention of cardiovascular diseases recommended by different guidelines in the Chinese Electronic Health Records Research in Yinzhou (CHERRY) study.@*METHODS@#A decision-analytic Markov model was used to simulate and compare different strategies of aspirin treatment, including: Strategy ①: Aspirin treatment for Chinese adults aged 40-69 years with a high 10-year cardiovascular risk, recommended by the 2020 Chinese Guideline on the Primary Prevention of Cardiovascular Diseases; Strategy ②: Aspirin treatment for Chinese adults aged 40-59 years with a high 10-year cardiovascular risk, recommended by the 2022 United States Preventive Services Task Force Recommendation Statement on Aspirin Use to Prevent Cardiovascular Disease; Strategy ③: Aspirin treatment for Chinese adults aged 40-69 years with a high 10-year cardiovascular risk and blood pressure well-controlled (< 150/90 mmHg), recommended by the 2019 Guideline on the Assessment and Management of Cardio-vascular Risk in China. The high 10-year cardiovascular risk was defined as the 10-year predicted risk over 10% based on the 2019 World Health Organization non-laboratory model. The Markov model simulated different strategies for ten years (cycles) with parameters mainly from the CHERRY study or published literature. Quality-adjusted life year (QALY) and the number needed to treat (NNT) for each ischemic event (including myocardial infarction and ischemic stroke) were calculated to assess the effectiveness of the different strategies. The number needed to harm (NNH) for each bleeding event (including hemorrhagic stroke and gastrointestinal bleeding) was calculated to assess the safety. The NNT for each net benefit (i.e., the difference of the number of ischemic events could be prevented and the number of bleeding events would be added) was also calculated. One-way sensitivity analysis on the uncertainty of the incidence rate of cardiovascular diseases and probabilistic sensitivity analysis on the uncertainty of hazard ratios of interventions were conducted.@*RESULTS@#A total of 212 153 Chinese adults, were included in this study. The number of people who were recommended for aspirin treatment Strategies ①-③ was 34 235, 2 813, and 25 111, respectively. The Strategy ③ could gain the most QALY of 403 [95% uncertainty interval (UI): 222-511] years. Compared with Strategy ①, Strategy ③ had similar efficiency but better safety, with the extra NNT of 4 (95%UI: 3-4) and NNH of 39 (95%UI: 19-132). The NNT per net benefit was 131 (95%UI: 102-239) for Strategy ①, 256 (95%UI: 181-737) for Strategy ②, and 132 (95%UI: 104-232) for Strategy ③, making Strategy ③ the most favorable option with a better QALY and safety, along with similar efficiency in terms of net benefit. The results were consistent in the sensitivity analyses.@*CONCLUSION@#The aspirin treatment strategies recommended by the updated guidelines on the primary prevention of cardiovascular diseases showed a net benefit for high-risk Chinese adults from developed areas. However, to balance effectiveness and safety, aspirin is suggested to be used for primary prevention of cardiovascular diseases with consideration for blood pressure control, resulting in better intervention efficiency.

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

Connotation of distal bleeding based on modern pathophysiological mechanism and application of Huangtu Decoction for acute coronary syndrome complicated with acute upper gastrointestinal hemorrhage in critical care medicine / 中国中药杂志

Huangtu Decoction, first recorded in Essentials from the Golden Cabinet(Jin Kui Yao Lue) from ZHANG Zhong-jing in Han dynasty, is used to treat distal bleeding. It is mainly treated for the syndrome of failing to control blood with spleen-yang deficiency. The connotation of distal bleeding is more extensive, including not only upper gastrointestinal bleeding in the traditional sense such as peptic ulcer bleeding, gastrointestinal tumors, gastric mucosal lesions, vascular dysplasia, esophagogastric variceal bleeding, and pancreatic and biliary tract injury, but also other anorectal diseases such as part colon and rectal cancer swelling or polyps, hemorrhoids, and anal fissure and other parts of bleeding such as epistaxis, thrombocytopenia, functional uterine bleeding, threatened abortion, and unexplained hematuria. Distal bleeding also involves syndromes of failing to keep part deficient and cold fluids in interior, such as nocturia, enuresis, clear nose, sweating, cold tears, and leucorrhea, and excessive gastrointestinal bleeding caused by anti-plate and anticoagulant drugs, unexplained positive in the fecal occult blood test, and other modern clinical new problems. The indications of Huangtu Decoction include not only lower blood, defecation before blood, distant blood, hematemesis, epistaxis, and other diseases in traditional Chinese medicine, but also three types of clinical manifestations including bleeding, deficiency syndrome, and stagnant heat syndrome. In the clinic, Huangtu Decoction can be used to treat acute upper gastrointestinal bleeding, acute coronary syndrome complicated with acute upper gastrointestinal bleeding, bleeding events caused by excessive antiplatelet and anticoagulant drugs, unexplained positive in the fecal occult blood test, gastrointestinal tumor with bleeding, thrombocytopenia, and other acute and critical diseases. The dosage of Cooking Stove Earthkey, Rehmanniae Radix, and Asini Corii Colla in Huangtu Decoction is the key to hemostasis.

Study on the comparative analysis of the efficacy of transmesenteric vein extrahepatic portosystemic shunt and transjugular intrahepatic portosystemic shunt in the treatment of cavernous transformation of portal vein / 中华肝脏病杂志

Objective: To compare the safety and efficacy of transmesenteric vein extrahepatic portosystemic shunt (TEPS) and transjugular intrahepatic portosystemic shunt (TIPS) in the treatment of cavernous transformation of the portal vein (CTPV). Methods: The clinical data of CTPV patients with patency or partial patency of the superior mesenteric vein treated with TIPS or TEPS treatment in the Department of Vascular Surgery of Henan Provincial People's Hospital from January 2019 to December 2021 were selected. The differences in baseline data, surgical success rate, complication rate, incidence rate of hepatic encephalopathy, and other related indicators between TIPS and TEPS group were statistically analyzed by independent sample t-test, Mann-Whitney U test, and Chi-square test. Kaplan-Meier survival curve was used to calculate the cumulative patency rate of the shunt and the recurrence rate of postoperative portal hypertension symptoms in both groups. Results: The surgical success rate (100% vs. 65.52%), surgical complication rate (6.67% vs. 36.84%), cumulative shunt patency rate (100% vs. 70.70%), and cumulative symptom recurrence rate (0% vs. 25.71%) of the TEPS group and TIPS group were statistically significantly different (P < 0.05). The time of establishing the shunt [28 (2141) min vs. 82 (51206) min], the number of stents used [1 (12) vs. 2 (15)], and the length of the shunt [10 (912) cm vs. 16 (1220) cm] were statistically significant between the two groups (t = -3.764, -4.059, -1.765, P < 0.05). The incidence of postoperative hepatic encephalopathy in the TEPS group and TIPS group was 6.67% and 15.79% respectively, with no statistically significant difference (Fisher's exact probability method, P = 0.613). The pressure of superior mesenteric vein decreased from (29.33 ± 1.99) mmHg to (14.60 ± 2.80) mmHg in the TEPS group and from (29.68 ± 2.31) mmHg to (15.79 ± 3.01) mmHg in TIPS group after surgery, and the difference was statistically significant (t = 16.625, 15.959, P < 0.01). Conclusion: The best indication of TEPS is in CTPV patients with patency or partial patency of the superior mesenteric vein. TEPS improves the accuracy and success rate of surgery and reduces the incidence of complications.

Hemorragia digestiva alta grave por fistula entre arteria esplénica y manga gástrica / Severe upper gastrointestinal bleeding due to fistula between splenic artery and gastric sleeve / Hemorragia digestiva alta grave devido a fístula entre artéria esplênica e manga gástrica

La hemorragia digestiva determinada por una fístula entre manga gástrica y seudoaneurisma de arteria esplénica o polo superior de bazo es infrecuente. Se presenta un caso clínico de una paciente de 52 años con antecedentes de cirugía de manga gástrica y fuga anastomótica. Ingresó por hemorragia digestiva alta grave. Se operó de emergencia y realizó punto hemostático sobre cara posterior de manga gástrica. Se reintervino por resangrado realizándose la gastrectomía y esplenopancreatectomía distal por solución de continuidad de arteria esplénica. Dada la inestabilidad hemodinámica se efectuó un esofagostoma y yeyunostomía, reconstruyéndose a los 8 meses con buena evolución.

Gastrointestinal bleeding caused by a fistula between the gastric sleeve and a pseudoaneurysm of the splenic artery or upper pole of the spleen is uncommon. A clinical case of a 52-year-old patient with a history of gastric sleeve surgery and anastomotic leak is presented. She was admitted for severe upper gastrointestinal bleeding. She underwent emergency surgery and performed a hemostatic stitch on the posterior face of the gastric sleeve. She underwent reoperation due to rebleeding, performing gastrectomy and distal splenopancreatectomy due to discontinuation of the splenic artery. Given the hemodynamic instability, an esophagostomy and jejunostomy were performed, reconstructing at 8 months with good evolution.

O sangramento gastrointestinal causado por uma fístula entre a manga gástrica e um pseudoaneurisma da artéria esplênica ou pólo superior do baço é incomum. Apresenta-se o caso clínico de um paciente de 52 anos com história de cirurgia de manga gástrica e fístula anastomótica. Ele foi internado por hemorragia digestiva alta grave.

Introducción: Los medicamentos antiulcerosos son utilizados frecuentemente en pacientes hospitalizados, sin embargo, a menudo este uso no está indicado. Objetivo: Describir la frecuencia de prescripción e indicación de medicamentos para prevenir el sangrado gastrointestinal en pacientes hospitalizados. Materiales y métodos: Estudio de corte trasversal, descriptivo, prospectivo del servicio de Medicina Interna de la Sociedad de Cirugía de Bogotá- Hospital de San José de Bogotá, Colombia. Se excluyeron pacientes con diagnóstico de sangrado gastrointestinal o antecedente de alergia a los medicamentos antiulcerosos. Se recolectaron datos demográficos, así como fármacos prescritos. Se determinó si la indicación del fármaco era adecuada y se identificó el tipo de error de prescripción. Resultados: Se incluyeron 179 pacientes, 102 (57%) mujeres. Promedio de edad de 61,3 años (±20,2). El principal diagnóstico de ingreso fue enfermedad infecciosa 76 (42,4%). Del total de pacientes, 165 (92,17%) recibieron medicamento para prevención del sangrado gastrointestinal. La indicación fue adecuada en 75 pacientes (41,89%). El error más frecuente fue el uso en pacientes de bajo riesgo de sangrado, 101 (97,1%). Conclusión: Un alto porcentaje de los pacientes recibió medicación para la prevención del sangrado gastrointestinal. En aproximadamente la mitad de estos no estaba indicada.

Introduction: Anti-ulcer medications are frequently used in hospitalized patients, yet their use is not usually indicated. Objective: To describe the frequency of prescription and indication of medications to prevent gastrointestinal bleeding in hospitalized patients. Materials and methods: A cross-sectional, descriptive, prospective study was carried out in the Internal Medicine service of the Surgery Society of Bogota-San Jose Hospital of Bogota (Colombia). Excluded patients were those with either a gastrointestinal bleeding diagnosis or a history of allergy to anti-ulcer medications. Demographic data and information regarding prescribed medications were collected. It was determined whether the medicine indication was adequate and the type of prescription error was identified. Results: 179 patients were included in the study, 57% (102) of which were women. The average age was 61.3 (±20.2) years old. Infectious disease was the main admission diagnosis (76; 42.4%). A 92.17% (165) of the total number of patients received medications to prevent gastrointestinal bleeding. This indication was adequate for 75 (41.89%) patients. The most frequent error was their use in bleeding low-risk patients (101; 97.1%). Conclusion: A high percentage of patients received medication to prevent gastrointestinal bleeding. However, in about half of these patients it was not indicated.

Introduction: Chronic hemorrhagic radiation proctitis (CHRP) appears secondary to pelvic radiotherapy. Argon plasma coagulation (APC) is an effective, safe, easy-to-use, and relatively inexpensive therapy. Objective: To describe the short- and long-term therapeutic response of APC in patients with CHRP, as well as to evaluate the quality of life before and after the intervention. Material and Methods: Observational, prospective case series study of 46 patients with CHRP, treated at the National Center for Minimally Access Surgery between 2017 and 2020. Summary measures and comparison of means (paired Student's t-test) were used for baseline and final hemoglobin, as well as for the quality of life scores applied before and after the intervention. The Kaplan-Meier method was used to determine the recurrence free time. A level of significance less than 0.05 was estimated for a 95 por ciento confidence interval. Results: A mean of 3,6 ± 2,394 APC sessions was required. The mean hemoglobin increased 1,9 g / L. Short-term therapeutic response was observed in 100 % of patients, and long-term in 91,3 por ciento. The mean score for quality of life decreased by 12,065 points (p˂ 0,00). The perceived global perception increased by a mean of 7,326 points (p˂ 0,00). Conclusions: APC has a good therapeutic response in the short and long term with few sessions and a low number of complications, with an improvement in the quality of life of the patients(AU)
