Pseudoquiste esplénico espontáneo: Enfoque diagnóstico y terapéutico. Reporte de un caso / Spontaneous splenic pseudocyst: Diagnostic and therapeutic approach. A case report

Introducción. Los quistes esplénicos son entidades anatómicas y clínicas poco frecuentes, con una incidencia aproximada de 0,07 %. Se clasifican como quistes esplénicos primarios, que contienen revestimiento epitelial y se subdividen en parasitarios y no parasitarios según su etiología, y quistes secundarios, que no poseen revestimiento epitelial en la luz quística y suelen ser el resultado de un traumatismo abdominal. Por lo general, son asintomáticos y se pueden encontrar de manera incidental durante estudios de imagen o en cirugía. Los síntomas están relacionados con el tamaño de los quistes. El tratamiento ideal es la resección quirúrgica, que puede ser total o parcial. Caso clínico. Paciente femenina de 23 años, sin antecedentes de trauma, con dolor abdominal intermitente, de varios meses de evolución. En los estudios imagenológicos se identificó un pseudoquiste esplénico gigante. Fue tratada mediante esplenectomía total por laparoscopia, sin complicaciones quirúrgicas. Resultados. Tuvo una adecuada evolución postoperatoria. Conclusión.El diagnóstico de quiste esplénico se realiza mediante estudios imagenológicos y se confirma con el análisis histopatológico. La esplenectomía total ha sido el tratamiento tradicional; sin embargo, ahora mediante la implementación de abordajes mínimamente invasivos, se prefiere la esplenectomía parcial, con el fin de preservar tejido esplénico y su función inmunológica.

Introduction.Splenic cysts are rare anatomical and clinical entities, with an approximate incidence of 0.07%. They are classified as primary splenic cysts, which contain epithelial lining and are subdivided into parasitic and non-parasitic depending on their etiology, and the secondary splenic cysts, which do not have an epithelial lining in the cystic lumen and are usually the result of abdominal trauma. They are usually asymptomatic and can be found incidentally during imaging studies or in surgery. The symptoms are related to the size of the cysts. The ideal treatment is surgical resection, which can be total or partial. Clinical case. A 23-year-old female patient, with no history of trauma, with intermittent abdominal pain, lasting several months. Imaging studies identified a giant splenic pseudocyst. She was treated by total laparoscopic splenectomy, without surgical complications. Results. She had an adequate postoperative evolution. Conclusion. The diagnosis of splenic cyst is made through imaging studies and confirmed with histopathological analysis. Total splenectomy has been the traditional treatment; however, now through the implementation of minimally invasive approaches, partial splenectomy is preferred, in order to preserve splenic tissue and its immunological function.

Esplenúnculo intrapancreático simulando neoplasia / Intrapancreatic splenunculus simulating neoplasia

Introducción. El esplenúnculo se ha descrito con una incidencia global del 10 al 30 %. Puede ser una entidad de origen congénito o adquirida, frecuentemente está asociada a trauma abdominal o antecedente de esplenectomía por diversas causas. Caso clínico. Mujer en edad media, con antecedente de trauma abdominal y esplenectomía por ruptura traumática, quien 30 años después presenta un cuadro de dolor abdominal. Los estudios imagenológicos identificaron una masa sólida intrapancreática. Resultados. Fue llevada a pancreatectomía distal. Los hallazgos histológicos e inmunohistoquímicos confirmaron que la masa pancreática correspondía a un esplenúnculo intrapancreático adquirido, asociado al evento traumático previo. Conclusión. Los esplenúnculos suelen constituir un "incidentaloma". Los estudios imagenológicos se encuentran limitados, pues la tomografía computarizada, la resonancia nuclear magnética y la ultrasonografía presentan características imagenológicas similares con los tumores pancreáticos hipervascularizados, por lo que se debe practicar el estudio histopatológico durante su valoración. Esta entidad se debe incluir dentro de los diagnósticos diferenciales, con mayor énfasis en aquellos pacientes con historia de trauma abdominal y esplenectomía asociada, un escenario en el que esta lesión puede simular una neoplasia sólida del páncreas, con características malignas.

Introduction. Splenunculus has been described with an overall incidence of 10 to 30%. It can be an entity of congenital or acquired origin, it is frequently associated with abdominal trauma or a history of splenectomy for various reasons. Clinical case. Middle-aged woman, with a history of abdominal trauma and splenectomy due to traumatic rupture, who 30 years later presents with abdominal pain. Imaging studies identified a solid intrapancreatic mass. Results. She was taken to OR for distal pancreatectomy. The histological and immunohistochemical findings confirmed that the pancreatic mass corresponded to an acquired intrapancreatic splenunculus, associated with the previous traumatic event. Conclusion. Splenuncles usually constitute an "incidentaloma". Imaging studies are limited, since computed tomography, magnetic resonance imaging, and ultrasonography present similar imaging characteristics with hypervascularized pancreatic tumors, so histopathological study must be included during their evaluation. This entity should be included in the differential diagnoses, with greater emphasis on those patients with a history of abdominal trauma and associated splenectomy, a scenario in which this lesion can simulate a solid neoplasm of the pancreas, with malignant characteristics.

Hidatidosis esplénica única / Isolated splenic hydatid disease

RESUMEN La hidatidosis es una parasitosis endémica en la Argentina. Los órganos más afectados son hígado y pulmón, pero la afectación esplénica única es infrecuente. El objetivo del trabajo es presentar 2 casos de hidatidosis esplénica única. Su diagnóstico presuntivo se realizó mediante el antecedente epidemiológico y los estudios por imágenes. Las serologías resultaron negativas en ambos casos. El tratamiento fue quirúrgico: se realizó esplenectomía laparoscópica total. Esta patología debe sospecharse en zonas endémicas ante la aparición de quistes esplénicos a pesar de presentar serologías negativas. La esplenectomía total evita la recidiva local y cavidades residuales; se prefiere el abordaje laparoscópico al disminuir la estadía hospitalaria y las complicaciones de la pared abdominal.

ABSTRACT Hydatid disease is an endemic parasitosis in Argentina. The liver and lungs are the organs more commonly affected, but isolated splenic involvement is rare. The aim of this study is to report two cases of isolated splenic hydatid disease. The diagnosis was suspected by epidemiology and imaging tests. The serologic tests were negative in both cases. Surgical management was decided and both patients underwent laparoscopic total splenectomy. This disease should be suspected in endemic areas in the presence of splenic cysts despite negative serologic tests. Total splenectomy prevents local recurrence and complications associated with the residual cavity. The laparoscopic approach is preferred as it results in a shorter length of hospital stay and fewer abdominal wall complications.

Aneurisma esplénico como hallazgo incidental durante el embarazo: a propósito de un caso / Splenic aneurysm as an incidental finding during pregnancy: a case report

El embarazo, especialmente el tercer trimestre, incrementa notablemente el riesgo de rotura de los aneurismas esplénicos. Cuando esto ocurre, se desencadena un cuadro clínico grave manifestado principalmente como un dolor abdominal agudo acompañado de inestabilidad hemodinámica. A pesar de la gran morbimortalidad tanto materna como fetal que esto conlleva, no existe hoy en día consenso sobre su manejo óptimo. Se presenta el caso de una secundigesta a la que se diagnostica de manera incidental un aneurisma en la arteria esplénica durante el segundo trimestre de gestación. Tras confirmarse dicho diagnóstico mediante resonancia magnética, se decide realizar una esplenectomía programada vía laparotómica en semana 24+2. La evolución maternofetal posterior fue favorable hasta la semana 40 en la que se produjo un parto eutócico. Los aneurismas esplénicos deben tratarse en todas las gestantes, independientemente de su tamaño o sintomatología, pues el beneficio supera los riesgos que supone una cirugía programada.

Pregnancy, especially the third trimester, significantly increases the risk of splenic aneurysm rupture. When this occurs, it results in a severe clinical presentation primarily characterized by acute abdominal pain accompanied by hemodynamic instability. Despite the substantial maternal and fetal morbidity and mortality associated with this condition, there is currently no consensus on its optimal management. We present the case of a second-time pregnant woman who incidentally received a diagnosis of a splenic artery aneurysm during the second trimester of gestation. After confirming this diagnosis through magnetic resonance imaging, it was decided to perform a scheduled laparotomic splenectomy at 24+2 weeks of gestation. Subsequent maternal and fetal evolution was favorable until the 40th week when a eutocic delivery occurred. Splenic aneurysms should be treated in all pregnant women, regardless of their size or symptomatology, as the benefits outweigh the risks associated with elective surgery.

Tumor pseudopapilar sólido de páncreas, una neoplasia inusual / Solid Pseudopapillary Tumor of the Pancreas, an Unusual Neoplasm

Presentación del caso. Se trata de una mujer de 26 años que presentó dolor en epigastrio e hipocondrio izquierdo, con aumento del perímetro abdominal y pérdida de 5 kg de peso corporal. En el examen físico se detectó una masa de gran tamaño en el epigastrio, con bordes regulares, ligeramente dolorosa al tacto y no móvil. Los estudios de imagen revelaron una neoplasia mixta en el cuerpo y cola pancreática. Intervención terapéutica. Se practicó una esplenopancreatectomía corpo-caudal, con extirpación completa del tumor. Evolución clínica. La paciente recibió cuidados especializados y vigilancia estrecha posquirúrgica en la unidad de cuidados intensivos, sin presentar complicaciones relevantes. Tras el alta hospitalaria, la paciente refirió un buen estado general en los controles de seguimiento, que incluyeron una tomografía realizada a los 12 meses, donde no se evidenciaron restos o recidivas tumorales

Case presentation. A 26-year-old woman who presented with pain in the epigastrium and left hypochondrium, with increased abdominal perimeter and loss of 5 kg of body weight. Physical examination revealed a large mass in the epigastrium, with regular borders, slightly painful to the touch and non-mobile. Imaging studies revealed a mixed neoplasm in the pancreatic body and tail. Treatment. A corpo-caudal splenopancreatectomy was performed, with complete removal of the tumor. Outcome. The patient received specialized care and close postoperative surveillance in the intensive care unit, with no relevant complications. After hospital discharge, the patient reported a good general condition in the follow-up controls, which included a computed tomography scan performed after 12 months, where no tumor remnants or recurrences were evidenced

Clinical observation of splenectomy with distal pancreatectomy during cytoreductive surgery in epithelial ovarian cancer / 复旦学报（医学版）

Objective To evaluate the safety and efficacy of splenectomy with distal pancreatectomy during cytoreductive surgery in epithelial ovarian cancer(EOC).Methods A total of 17 patients from Zhongshan Hospital,Fudan University and the First Affiliated Hospital of University of Science and Technology of China(Anhui Provincial Hospital)received splenectomy with distal pancreatectomy during cytoreductive surgery in EOC were recruited.Their clinicopathological characteristics,postoperative complications and survival situation were retrospective analyzed.Results Of the 17 patients,there were 13 primary cases and 4 recurrent cases.Eleven cases(64.7%)had preoperative imaging finding with metastatic lesions in the splenic hilum,among whom 6 cases had distal pancreas metastasis during the operation.The drainage was placed in the splenic fossa for the measurement of amylase levels in drain fluid and was removed after 8(3-12)days.There were 4 patients had postoperative pancreatic fistula(POPF)of grade A,3 patients had POPF of grade B and no POPF of grade C occurred.The 2 patients with POPF of grade B improved after percutaneous drainage,and the rest recovered with somatostatin,antibiotic drugs and medicines without perioperative mortality.The interval between surgery to chemotherapy was 17.5(13-37)days.The median follow-up time was 14(4-64)months and the median progression-free survival was 10(5-32)months.Conclusion Splenectomy with distal pancreatectomy as part of cytoreduction surgery in EOC is needed for optimal resection,and the complication of pancreatic fistula could be managed conservatively.

The assessment of hepatic hemodynamic characteristics in cirrhotic patients with splenectomy based on iodine map of dual-source CT / 实用放射学杂志

Objective To investigate the hepatic hemodynamic characteristics of cirrhotic patients with splenectomy using iodine map of dual-source computed tomography(DSCT).Methods Twenty-four cirrhotic patients with splenectomy were selected as a study group,41 cirrhotic patients without splenectomy as a cirrhosis group and other 32 patients with normal liver as a control group.The iodine concentration(IC)in hepatic arterial and venous phases was measured on the iodine map,and the arterial iodine fraction(AIF)and portal venous iodine concentration(PVIC)were calculated.Receiver operating characteristic(ROC)curves were plotted and the area under the curve(AUC)was recorded to evaluate the diagnostic efficacy of each parameter using the DeLong test.Results IC in arterial phase and AIF were significantly higher,and IC in venous phase and PVIC were significantly lower in study group(P<0.05).The AUC values of the four parameters between study group and cirrhosis group were 0.735,0.992,0.943,and 0.994,respectively.Conclusion DSCT iodine map is helpful for clinical quantitative assessment of hepatic hemodynamic characteristics in cirrhotic patients with splenectomy,and the PVIC has optimal independent diagnostic performance.

Efficacy of Partial Splenic Artery Embolization Versus Splenectomy for Hypersplenism Secondary to Liver Cirrhosis:a Meta-analysis / 医学研究杂志

Objective To systematically evaluate the efficacy of partial splenic artery embolization(PSE)and splenectomy in the treatment of secondary hypersplenism in liver cirrhosis.Methods PubMed,Cochrane Library,Embase,CNKI,Wan Fang were searched to collect randomized controlled trials and cohort studies about the efficacy of PSE versus splenectomy in the treatment of hyper-splenism secondary to liver cirrhosis from inception to October 30,2021.Two reviewers screened the literature,extracted data,and as-sessed the risk of bias of included studies.Meta-analysis was then conducted.Results A total of 14studies were included with 1092 patients.The results of the meta-analysis showed that there was no significant difference in postoperative leukocyte levels at 1 week,1 month,and 1 year after surgery between the PSE group and the splenectomy group.However,6months after surgery,the level of postop-erative leukocyte in the splenectomy group was significantly higher than that in the PSE group.For postoperative platelet counts,there was no significant difference at 1 month and 1 year after surgery between the two groups.However,1 week(MD=-65.46,95％CI:-116.39--14.52,P=0.01)and 6months(MD=-117.99,95％CI:-229.71--6.27,P=0.04)after surgery,the level of postoperative platelet in splenectomy group was significantly higher than that in PSE group.There was no significant difference in postoperative erythro-cyte levels at 1 week,1 month,and 1 year after surgery between the two groups.The level of postoperative natural killer cells in the PSE group was significantly higher than that in the splenectomy group at 1 month(MD=6.02,95％CI:4.27-7.77,P＜0.001)and 1 year(MD=3.53,95％CI:1.68-5.37,P=0.0002)after surgery.Compared with splenectomy group,PSE group exhibited less intraopera-tive bleeding(MD=-73.92,95％CI:-89.39--58.45,P＜0.001),less hospitalization costs(MD=-0.80,95％CI:-1.27--0.34,P=0.0008)and shorter length of stay(MD=-4.08,95％CI:-5.22--2.95,P＜0.001).Conclusion The current evi-dence shows that PSE has certain short-term and long-term effects on hypersplenism.Compared with splenectomy,it has less surgical trauma,less hospital stay and less cost,easy to control complications,and retains some immune function,which is worth spreading in the clinic.Limited by the quantity and quality of the included literature,more high-quality studies are needed to confirm the above conclu-sions.

Clinical observation of preemptive analgesia with pentazocine for perioperative pain management in partial splenectomy / 中国基层医药

Objective:To investigate the clinical effect of preemptive analgesia with pentazocine on perioperative pain management in partial splenectomy.Methods:A total of 100 patients with traumatic splenic rupture who underwent partial splenectomy at Yiwu Central Hospital between October 2019 and November 2021 were randomly assigned to either the control group or the study group, with 50 patients in each group using the random number table method. Both groups received patient-controlled analgesia postoperatively. Additionally, the study group received intravenous pentazocine administration before surgery. The amount of anesthetic used during surgery, postoperative anesthesia recovery indices, postoperative pain response, serum inflammatory factor levels, and the number of effective patient-controlled analgesia pump presses within 48 hours postoperatively were recorded and evaluated. Any adverse drug reactions were also monitored.Results:The dosages of propofol [(462.24 ± 27.13) mg] and remifentanil [(365.98 ± 26.78) μg] in the study group were significantly lower than those in the control group [(511.82 ± 26.32) mg, (406.86 ± 26.08) μg, t = 14.49, 12.63, both P < 0.001). The recovery time of spontaneous breathing [(6.86 ± 0.97) minutes], anesthesia recovery time [(13.24 ± 0.82) minutes] and extubation time [(17.14 ± 1.07) minutes] were significantly shorter than those in the control group [(7.62 ± 0.90) minutes, (14.32 ± 0.84) minutes, (18.22 ± 1.06) minutes, t = 5.80, 8.58, 6.93, all P < 0.001]. The Visual Analogue Scale (VAS) scores in the study group were significantly lower than those in the control group at 24 and 48 hours after surgery, both in resting and coughing state ( t = 7.82, 9.31, 4.95, 8.47, all P < 0.001). The serum levels of tumor necrosis factor-alpha, interleukin-1, and interleukin-6 were significantly lower in the study group than in the control group ( t = 21.53, 25.61, 18.45, 16.90, 17.33, 14.86, all P < 0.001), while the serum level of interleukin-10 was significantly higher in the study group than in the control group ( t = -20.85, -19.61, both P < 0.001). The number of effective patient-controlled pump analgesia presses within 48 hours postoperatively in the study group [(6.24 ± 1.17) times] was significantly lower than that in the control group [(10.26 ± 1.34) times, t = 12.95, P < 0.05). In addition, the overall incidence of adverse drug reactions in the study group [4.00% (2/50)] was significantly lower than that in the control group [18.00% (9/50), χ2 = 5.01, P < 0.05]. Conclusion:Preemptive analgesia with pentazocine for patients undergoing partial splenectomy can effectively reduce the dosage of anesthetics during surgery and the dosage of analgesics after surgery, enhance the recovery from postoperative anesthesia, suppress postoperative inflammatory reactions, alleviate pain responses, and minimize the risk of adverse drug reactions.

Portal thrombosis after surgical treatment of schistosomatic portal hypertension

SUMMARY OBJECTIVE: Several studies have investigated the correlation between the effects of different surgical treatments and laboratory exams for schistosomal portal hypertension, especially concerning portal system thrombosis. The etiopathogenic factors of this thrombosis are not fully understood. In this study, the correlation between surgical treatment for schistosomal portal hypertension and the occurrence of postoperative portal system thrombosis was investigated. METHODS: A total of 61 patients who underwent surgical treatment for schistosomal portal hypertension were distributed into four groups: Patients in Group 1 (n=12) underwent portal variceal disconnection associated with splenic artery ligation and spleen preservation. Patients in Group 2 (n=20) underwent portal variceal disconnection and total splenectomy. Patients in Group 3 (n=20) underwent portal variceal disconnection with subtotal splenectomy, preserving the upper splenic pole supplied by the splenogastric vessels. Patients in Group 4 (n=9) underwent portal variceal disconnection with total splenectomy and autogenous splenic implants on the greater omentum. Late postoperative portal vein thrombosis was diagnosed using Doppler ultrasound. RESULTS: Over the 10-year follow-up, portal vein thrombosis occurred in 26 operated patients (42.6%), with no significant difference observed among the four surgical groups (p=0.217). Most of the thrombi only partially occluded the portal system veins. All the patients presented with a thrombus inside the portal vein. There was no difference in hematological and biochemical tests between groups with or without portal vein thrombosis. CONCLUSIONS: Portal vein thrombosis is often observed in the late postoperative period, irrespective of the surgical treatment employed, and is not associated with patient characteristics or any hematological and biochemical tests.

Littoral cell angioma of the spleen: case report and literature review

ABSTRACT Littoral cell angioma is an extremely rare splenic vascular tumor originating from the cells lining the splenic red pulp sinuses. Approximately 150 cases of littoral cell angioma have been reported since 1991. Its clinical manifestation is usually asymptomatic and is mostly diagnosed as an incidental finding through abdominal imaging. Herein, we present a case of littoral cell angioma in a 41-year-old woman with no previous comorbidities, which initially presented as a nonspecific splenic lesion diagnosed on imaging in the emergency room. The patient was treated through laparoscopic intervention.

Quiste esplénico epidérmico infectado. Reporte de caso

Los quistes esplénicos son infrecuentes y presentan una baja incidencia (0.07%). Las etiologías son varias, pero en su mayoría se deben a parasitarios y no parasitarios. Entre los primeros se encuentran los quistes hidatídicos por equinococosis que son más comunes sobre todo en zonas endémicas. En el siguiente trabajo se presenta el caso de una paciente de sexo femenino de 17 años de edad que consulta por un cuadro de 6 días de evolución que inicia con dolor, tipo puntada de moderada intensidad, localizado en hipocondrio izquierdo, acompañado de fiebre graduada en 38 grados con escalofríos.

Splenic cysts are uncommon and have a low incidence rate (0.07%). The etiologies are diverse, but mostly attributed to both parasitic and non-parasitic origins. Among the former, hydatid cysts due to echinococcosis are more prevalent, especially in endemic areas. This report describes the case of a 17-year-old female patient who presented with a 6-day history of pain, of moderate intensity and stabbing type, localized in the left hypochondrium. The pain was accompanied by a fever reaching 38 degrees Celsius and chills.

Manejo de traumatismo esplénico en el Hospital Nacional de Itauguá

Introducción: El bazo es el órgano más afectado en el traumatismo cerrado de abdomen en el adulto. El traumatismo esplénico puede ser por lesiones no penetrantes (cerrado) o por lesiones penetrantes. Las pruebas de imagen más útiles a la hora de evaluar el trauma esplénico son la ecografía de evaluación enfocada para traumatismo (FATS, por sus siglas en inglés) y la tomografía computarizada (TC). Objetivo: describir el manejo del traumatismo esplénico en el Hospital Nacional de Itauguá. Metodología: Se trata de un estudio observacional, descriptivo de serie de casos en el cual se incluyó a pacientes adultos con diagnóstico de traumatismo esplénico que fueron atendidos en la urgencia de adultos del Hospital Nacional de Itauguá entre enero de 2018 y enero de 2020. Se incluyó a la totalidad de los pacientes atendidos y no se excluyó a ninguno. Las variables que se estudiaron fueron sexo, edad, tipo de trauma, mecanismo de trauma, hemodinamia, imagenología (FATS y TC), grado de la lesión (I al V), cirugía de urgencias, cirugía realizada, tratamiento no operatorio, éxito del tratamiento, días de internación, óbito y lesiones asociadas. Resultados: Se presenta una serie de 10 casos, todos son del sexo masculino y cuya edad tiene una media de 30,7 ± 10,58 años. En todos los casos el trauma fue cerrado. El mecanismo del trauma fue accidente con motocicleta en el 80 %. En cuanto a la hemodinamia el 80 % estuvo estable, el 100 % se realizó la FACTS y el 80 % la TC. El grado más frecuente fue el grado IV con 40 %. Discusión: el manejo del trauma esplénico ha cambiado a lo largo del tiempo, actualmente se busca un manejo no quirúrgico, sin embargo, esto depende de las condiciones del paciente.

Introduction: The spleen is the most affected organ in blunt trauma to the abdomen in the adult. Splenic trauma can be due to non-penetrating (blunt) or penetrating injuries. The most useful imaging tests when evaluating splenic trauma are focused assessment sonography for trauma (FATS) and computed tomography (CT). Objective: to describe the management of splenic trauma at the Hospital Nacional de Itauguá. Methodology: this is an observational, descriptive case series study in which adult patients with a diagnosis of splenic trauma who were seen in the adult emergency department of the Hospital Nacional de Itauguá between January 2018 and January 2020 were included. All patients attended were included and none were excluded. The variables studied were sex, age, type of trauma, mechanism of trauma, hemodynamics, imaging (FATS and CT), grade of injury (I to V), emergency surgery, surgery performed, non-operative treatment, treatment success, days of hospitalization, death and associated injuries. Results: We present a series of 10 cases, all of them male, with a mean age of 30.7 ± 10.58 years. In all cases the trauma was blunt. The mechanism of trauma was motorcycle accident in 80 %. Regarding hemodynamics, 80% were stable, 100% underwent FACTS and 80% underwent CT. The most frequent grade was grade IV with 40%. Discussion: the management of splenic trauma has changed over time, currently non-surgical management is sought, however, this depends on the patient's conditions.

Trombocitopenia inmune primaria refractaria y el uso de terapia combinada, reporte de caso / Refractory primary immune thrombocytopenia and use of combined therapy, case report

RESUMEN La trombocitopenia inmune primaria es un trastorno autoinmune adquirido, caracterizado por una destrucción plaquetaria excesiva, derivada de la producción de anticuerpos contra la membrana plaquetaria, conllevando a un alto riesgo de hemorragia para el paciente. Actualmente, la piedra angular del tratamiento sigue siendo el uso de agentes de primera línea como los glucocorticoides y la inmunoglobulina intravenosa. Sin embargo, en algunos casos los pacientes pueden ser refractarios a estos, con el requerimiento de terapias de segunda y tercera línea. Se presenta el caso clinico de una paciente de 25 años con historia de trombocitopenia inmune primaria con presentación severa por la presencia de sangrado gastrointestinal y estado anémico asociado, con refractariedad a diferentes estrategias de tratamiento, incluida la esplenectomia, requiriendo posterior manejo combinado con Ri-tuximab, con el cual se logró mantener un recuento plaquetario adecuado. Consideramos que este caso toma interés clinico dado los escasos reportes de casos de esta condición y la limitada evidencia que se tiene ante las terapias secuenciales en pacientes refractarios a tratamiento de primera linea.

ABSTRACT Primary immune thrombocytopenia is an acquired autoimmune disorder, characterized by platelet destruction, resulting from the production of antibodies against the platelet membrane, involving ahigh risk of bleeding for the patient. Currently, the cornerstone of treatment is the use of first-line agents such glucocorticoids and intravenous immunoglobulin. However, in some patients may be refractory to these agents, requiring the use of second and third line agents. We present the case of a 25-year-old female patient with a history of primary immune thrombocytopenia with severe presentation due to the presence of gastrointestinal bleeding and associated anemic state, with refractoriness to different treatment including splenectomy and the subsequent use of Rituximab, which was used to maintain an adequate platelet count. We consider that this case is of clinical interest given the scarce case reports of this condition and the limited evidence on sequential therapies in patients refractory to first line treatment.

Hemoperitoneo secundario a lesión esplénica tras colonoscopia diagnóstica. Una complicación infrecuente

Introducción: La colonoscopia es una herramienta básica en el estudio de patologías del área colorrectal, así como uno de los pilares del screening del cáncer de colon y recto. Sin embargo, no es un procedimiento exento de riesgos, algunos de ellos con elevada morbimortalidad. Caso Clínico: Varón de 55 años con enolismo crónico y hepatopatía por Virus Hepatitis C y Enfermedad Pulmonar Obstructiva Crónica. En estudio por diarrea se solicita una ecografía de abdomen donde, como único hallazgo, se muestra una lesión de 7 mm a nivel de páncreas y una colonoscopia con intención diagnóstica que no muestra alteraciones significativas. Con la sospecha de que la lesión pancreática pudiese ser la causa del cuadro diarreico, se realiza un escáner abdominal donde se muestra una colección subcapsular a nivel esplénico de 11 × 3 cm compatible con hematoma sin signos de sangrado activo. Dada la estabilidad hemodinámica, se inicia manejo conservador, con empeoramiento del dolor abdominal e hipotensión en las siguientes 12 h. Se repite prueba de imagen objetivando aumento de hematoma esplénico y líquido libre intraabdominal. Se indica cirugía urgente donde se evidencia hemoperitoneo secundario a lesión esplénica que obliga a realizar esplenectomía. Conclusión: La presencia de una posible lesión esplénica yatrogénica se debe tener en cuenta en el diagnóstico diferencial en un paciente con dolor abdominal de inicio agudo y anemización o alteración del estado hemodinámico dentro de las primeras 24-48 h tras la realización de una colonoscopia.

Introduction: Colonoscopy is a basic tool in the study of pathology of the colorectal area, as well as one of the pillars of colon and rectal cancer screening. However, it is not a risk-free procedure, some of them with high morbimortality. Case Report: 55-year-old male with chronic alcoholism and hepatopathy due to HCV, COPD. During a study for diarrhea, an ultrasound of the abdomen revealed a 7 mm pancreas tumor, and a diagnostic colonoscopy showed no significant alterations. With the suspicion that the pancreatic lesion could be the cause of the diarrhea, an abdominal scan was performed showing a subcapsular collection at the splenic level of 11 × 3 cm compatible with hematoma without signs of active bleeding. Due to the hemodynamic stability, conservative management was decided, with worsening abdominal pain and hypotension in the following 12 hours. A new imaging test showed an enlarged splenic hematoma and free abdominal fluid suggestive of hemoperitoneum. Urgent surgery found hemoperitoneum secondary to splenic lesion and splenectomy was required. Conclusion: The presence of a possible iatrogenic splenic lesion should be considered in the differential diagnosis in a patient with acute onset abdominal pain and anemia or hemodynamic status alteration within the first 24-48 hours after colonoscopy.

Rotura atraumática idiopática de bazo

Objetivo: Se presenta un caso de rotura esplénica atraumática. Caso Clínico: Mujer joven que estando ingresada y con reposo relativo por colección intraabdominal cercana a la colostomía presenta rotura de bazo. Se realiza esplenectomía urgente evidenciando gran hemoperitoneo y rotura esplénica. Discusión y conclusiones: El diagnóstico de rotura esplénica atraumática debe tenerse en cuenta en los pacientes con dolor abdominal de aparición súbita ya que un retraso en el diagnóstico puede conducir a un aumento de la tasa de mortalidad.

Objective: A case of idiopathic atraumatic splenic rupture is presented. Clinical case: A young woman was admitted to hospital with relative rest due to an intra-abdominal collection near the colostomy and presented with a ruptured spleen. An urgent splenectomy was performed, revealing large haemoperitoneum and splenic rupture. Discussion and conclusions: the diagnosis of atraumatic splenic rupture should be taken into account in patients with sudden onset abdominal pain, as a delay in diagnosis may lead to an increased mortality rate.

Principales modificaciones asociadas a la esplenectomía / Main modifications associated with splenectomy

Introducción. El bazo es un órgano linfoide implicado en el reconocimiento antigénico, la depuración de patógenos y la remoción de eritrocitos envejecidos o con inclusiones citoplasmáticas. La esplenectomía es una técnica utilizada tanto para el diagnóstico (linfomas), el tratamiento (trombocitopenia inmune, anemia hemolítica adquirida) y la curación (microesferocitosis hereditaria) de diversas enfermedades. Métodos. Describir los principales cambios hematológicos y complicaciones asociadas al procedimiento de esplenectomía. Discusión. Los cambios posteriores a la esplenectomía pueden ser inmediatos, como la aparición de cuerpos de Howell-Jolly, la trombocitosis y la presencia de leucocitosis durante las primeras dos semanas. Otras complicaciones tempranas incluyen la presencia de trombosis, en especial en pacientes con factores de riesgo secundarios (edad, sedentarismo, manejo hospitalario, obesidad) o un estado hipercoagulable (diabetes, cáncer, trombofilia primaria), siendo tanto el flujo de la vena porta como el volumen esplénico los principales factores de riesgo para su aparición. Las complicaciones tardías incluyen la alteración en la respuesta inmune, aumentando el riesgo de infecciones por bacterias encapsuladas, en conjunto con una reducción en los niveles de IgM secundario a la ausencia de linfocitos B a nivel de bazo. Debido al riesgo de infecciones, principalmente por Streptococcus pneumoniae, la esplenectomía parcial se ha considerado una opción. Conclusión. Una adecuada valoración de la indicación de esplenectomía y la identificación precoz de complicaciones posoperatorias son fundamentales para reducir la mortalidad asociada a la esplenectomía

Introduction. The spleen is a lymphoid organ involved in antigen recognition, pathogen clearance, and removal of aged erythrocytes or those with cytoplasmic inclusions. Splenectomy is a technique used for diagnosis (lymphomas), treatment (immune thrombocytopenia, acquired hemolytic anemia), and cure (hereditary microspherocytosis) of various diseases. Methods. To describe the main hematological changes and complications associated with the splenectomy procedure. Discussion. Changes after splenectomy can be considered immediate: the appearance of Howell-Jolly bodies, thrombocytosis, and leukocytosis during the first two weeks. Other complications include the presence of thrombosis, especially in patients with risk factors (age, sedentary lifestyle, long hospital stay, obesity) or a hypercoagulable state (diabetes, cancer, primary thrombophilia), with both portal vein flow and splenic volume being the main risk factors for its appearance. Late complications include altered immune response, increased risk of infections by encapsulated bacteria, and a reduction in IgM levels secondary to the absence of B lymphocytes in the spleen; due to the risk of diseases mainly by Streptococcus pneumoniae, partial splenectomy has been considered an option. Conclusion. An adequate assessment of the indication for splenectomy and the early identification of complications are essential to reduce the mortality associated with splenectomy

Procedimiento anestésico-quirúrgico en un adulto con esplenomegalia por linfoma primario de bazo / Anesthetic-surgical procedure in an adult with splenomegaly due to primary spleenic lymphoma: en

Se describe el caso clínico de un adulto joven de 30 años de edad, con antecedente de buena salud, quien fue asistido en el Servicio de Cirugía del Hospital Universitario Manuel Ascunce Domenech en Camagüey por presentar aumento de volumen en la región abdominal de dos meses de evolución, concomitante con astenia, anorexia, vómitos y pérdida de peso. En el examen físico resultaron notables el abdomen globuloso (bazo palpable) sin dolor, un hematoma periumbilical y múltiples adenopatías supraclaviculares; en tanto, en los estudios imagenológicos se evidenció la presencia de esplenomegalia. Se realizó esplenectomía con administración de anestesia general endotraqueal y en el estudio histopatológico de la muestra resecada se confirmó el diagnóstico de linfoma primario del bazo.

The case report of a 30-year-old young adult with a history of good health is described, who was assisted at the Surgery Service of Manuel Ascunce Domenech University Hospital in Camagüey due to volume increase in the abdominal region with a course of two months, concomitant with asthenia, anorexia, vomits and weight loss. Physical examination revealed a globular abdomen (palpable spleen) with no pain, a periumbilical hematoma, and multiple supraclavicular adenopathies; meanwhile, in the imaging studies splenomegaly was evidenced. Splenectomy was performed with administration of general endotracheal anesthesia and the histopathological study of the resected sample confirmed the diagnosis of primary spleenic lymphoma.

Giant splenic cysts discovered incidentally after early abortion

Splenic cysts are rare tumors, grouped into parasitic and non-parasitic cysts, no-parasitic cysts are further classified into primary and secondary cysts depending on the mucous membrane of the cyst, radiological imaging allows the diagnosis to be made but confirmation of the diagnosis is based on an atom-o-pathological examination of the part. surgical treatment is the cornerstone of symptomatic and complicated splenic cysts. The conservative treatment is a reference for splenic cysts. We report the case of a young woman who was presented with a simple cyst of the spleen.

Hemodynamic characteristics of proper hepatic artery and portal vein in patients after splenectomy and devascularization / 临床肝胆病杂志

Objective To investigate the characteristics of hemodynamics of proper hepatic artery and portal vein after splenectomy and devascularization. Methods The clinical data of 103 patients with portal hypertension who underwent splenectomy and devascularization in the Capital Medical University-Affiliated You'an Hospital from April 2014 to February 2019 were retrospectively analyzed. Their hemodynamics of the proper hepatic artery and portal vein were recorded before and 1 week-, and 1-, 3-, 6-, 12-, and 24-months after surgery and then statistically analyzed. Continuous data with normal distribution were compared using paired-samples t test. Results Compared with the before surgery data, the portal vein diameter, portal vein flow, maximum velocity, and average velocity of the portal vein were all significantly decreased 1-week-, 1-, 3-, 6-, 12-, and 24-months after splenectomy and devascularization (all P < 0.05). The blood flow and velocity of the proper hepatic artery was significantly increased 1 week and 1 month after surgery (all P < 0.05); however, there was no statistically significant difference at 3-, 6-, 12-, and 24-months after surgery. Conclusion The diameter, flow, and flow velocity of the portal vein after splenectomy and devascularization were significantly lower than those before surgery, whereas the proper hepatic artery flow and flow velocity were increased within 1 month after surgery and then returned back to the pre-surgery levels 3 months after surgery.
