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.

Hematoma subcapsular esplénico espontáneo y mononucleosis infecciosa: una asociación de interés para el cirujano

La rotura espontánea de bazo es una complicación infrecuente pero muy grave de la mononucleosis infecciosa. Dada la urgencia con la que suele presentarse tal situación, la esplenectomía suele ser la opción quirúrgica más utilizada. Presentamos el caso de un paciente en el que con el diagnóstico de rotura esplénica espontánea se somete a laparoscopia diagnóstica en la que se consigue la preservación del bazo con buena evolución clínica. A la luz de este paciente, consideramos que, en caso de estabilidad clínica y hematomas subcapsulares de bazo, la laparoscopia con preservación esplénica es una opción viable y con buenos resultados. (provisto por Infomedic International)

Spontaneous rupture of the spleen is a rare but very serious complication of infectious mononucleosis. Given the urgency with which such a situation usually presents, splenectomy is usually the most used surgical option. We present the case of a patient diagnosed with spontaneous splenic rupture who underwent diagnostic laparoscopy in which spleen preservation was achieved with good clinical evolution. In the light of this patient, we consider that, in the case of clinical stability and subcapsular haematomas of the spleen, laparoscopy with splenic preservation is a viable option with good results.

Secondary amyloidosis with concomitant gastric GIST and gastric adenocarcinoma - A case report

Secondary amyloidosis is a well-established entity and has been described in association with chronic inflammatory conditions such as rheumatoid arthritis, ankylosing spondylitis, bronchiectasis, tuberculosis, etc., It has also been reported in association with neoplasms such as Hodgkin's lymphoma, Waldenstrom's macroglobulinemia, renal cell carcinoma, lung carcinoma, etc. However, only a few case reports documenting the association of amyloidosis with gastrointestinal tumor (GIST) and gastric adenocarcinoma are available in the literature. Hereby, we report a case of a 74-year-old male who presented with colicky abdominal pain and vomiting. Ultrasonography revealed a common bile duct (CBD) stone and a small extra-luminal gastric mass. Endoscopic retrograde cholangiopancreatography (ERCP) was performed to remove the CBD stone which revealed an incidental finding of gastric ulcer. A biopsy was taken from the gastric ulcer which on histopathological examination was confirmed as adenocarcinoma leading onto total gastrectomy. During total gastrectomy, an inadvertent injury to the spleen led to simultaneous splenectomy. Multiple samples from the gastric ulcer, the extra-luminal gastric mass, and the spleen were subjected to histopathological examination. Gastric ulcer was confirmed as adenocarcinoma, gastric extra-luminal mass was confirmed as GIST, and splenic examination revealed widespread deposition of amyloid which on Congo-red stain imparted an apple-green birefringence on polarizing microscopy. To the best of our knowledge, this is the first-ever case of such an association where gastric adenocarcinoma occurred with concomitant gastric GIST and secondary amyloidosis of the spleen.

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.

Absceso esplénico en un paciente adulto. Reporte de caso

El absceso esplénico es una entidad poco común. Se define como la presencia de una lesión ocupante de espacio en el bazo asociada a infección. Ha sido descrito en 0,14-0,7 % de los estudios de autopsias. Se presenta el caso de un paciente de 60 años, de color de piel blanca, que acudió al hospital por presentar fiebre y diarreas, con dolor en fosa lumbar izquierda. Fue ingresado y trasladado a Unidad de Cuidados Intensivos debido a fallo renal agudo por deshidratación. Al trasladarse a sala abierta se diagnosticó un absceso esplénico mediante ultrasonido y tomografía. No se decidió operar en ese momento porque no tenía criterio. Posteriormente sufrió de abdomen agudo y shock séptico por ruptura del absceso hacia cavidad abdominal y fue intervenido de urgencia; se realizó esplenectomía y toilette de la cavidad. Su evolución posterior fue favorable. Por lo poco común de esta entidad, se decidió la publicación del caso.

The splenic abscess is a rare entity. It is defined as the presence of a space-occupying lesion in the spleen associated with infection. It has been described in 0.14-0.7% of autopsy studies. The case of a 60-years-old patient, white-skinned, who came to the hospital due to fever and diarrhea, with pain in the left lumbar fossa is presented. He was admitted and transferred to the Intensive Care Unit due to acute renal failure due to dehydration. When transferred to the open room, a splenic abscess was diagnosed by ultrasound and tomography. It was not decided to operate at that time because there are no criteria. Subsequently, he presented acute abdomen and septic shock due to rupture of the abscess into the abdominal cavity and underwent emergency surgery, performing splenectomy and the cavity's toilette. His subsequent evolution was positive. Due to the unusual nature of this entity, it was decided to publish the case.

Tumor Sólido Pseudopapilar de Páncreas en varón

Objetivo: Comunicar el caso de un varón diagnosticado de tumor sólido pseudopapilar de páncreas (TSPP). Esta patología afecta fundamentalmente a mujeres jóvenes, siendo extremadamente infrecuente en hombres. Caso Clínico: Varón de 40 años diagnosticado por TC de masa intraabdominal sólida bien delimitada, de 12,5 × 13 × 8,5 cm, heterogénea, con calcificaciones periféricas y realce tras la administración de contraste en fase portal, dependiente de cuerpo-cola pancreática. Se realiza puncion, no concluyente. La laparotomía exploradora mostró tumoración sólida dependiente de cola pancreática que incluye vasos esplénicos. Se liberó el tumor de forma periférica, requiriendo pancreatectomía distal y esplenectomía. El resultado AP informó neoplasia pseudopapilar sólida de cola pancreática de bajo grado de malignidad, bien diferenciado (G1). Alta hospitalaria al 12° día sin complicaciones. Actualmente libre de enfermedad tras dos años de la intervención. Discusión: Este tumor infrecuente representa el 1%-3% de las neoplasias pancreáticas. El 90% afecta a mujeres jóvenes, con proporción de mujeres a hombres de 4:1. En estos, tiene mayor potencial maligno con peor pronóstico. Conclusión: La baja incidencia en varones puede dificultar el diagnóstico. Sin embargo, debemos tenerlo en cuenta en el diagnóstico diferencial, ya que el tratamiento quirúrgico radical aumenta significativamente la supervivencia al evitar la recurrencia local y las metástasis a distancia, lo que supone un reto quirúrgico.

Objective: To report the case of a male diagnosed with a solid pseudopapillary tumor of the páncreas. This pathology fundamentally affects young women, being extremely infrequent in men. Clinical Case: A 40-year-old man diagnosed by CT with a well-defined solid intra-abdominal mass, 12.5 × 13 × 8.5 cm, heterogeneous, with peripheral calcifications and enhancement after contrast administration in the portal phase, dependent on the body-tail of the pancreas. Fine needle puncture is performed, inconclusive. The exploratory laparotomy showed a solid tumor dependent on the pancreatic tail that included splenic vessels. The tumor was released peripherally, requiring distal pancreatectomy and splenectomy. The AP result reported solid pseudopapillary neoplasm of the pancreatic tail of low grade of malignancy, well differentiated (G1). Hospital discharge on the 12th day without complications. Currently free of disease two years after the intervention. Discussion: This rare tumor represents 2%-3% of pancreatic neoplasms. 90% affects young women, with a ratio of women to men of 4:1. In these, it has greater malignant potential with worse prognosis. Conclusion: The low incidence in males can make diagnosis difficult. However, we must take it into account in the differential diagnosis, since radical surgical treatment significantly increases survival by avoiding local recurrence and distant metastases, which is a surgical challenge.

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

Pancreatectomía izquierda laparoscópica: ¿la sistematización de la técnica es de utilidad? / Laparoscopic left pancreatectomy: is systematization of the technique useful?

RESUMEN Antecedentes: la pancreatectomía izquierda laparoscópica es un procedimiento de alta complejidad que debe ser sistematizado para reducir complicaciones y tiempos quirúrgicos. Objetivo: Describir los resultados con una técnica sitematizada de esplenopancreatectomía laparoscópica. Material y métodos: se seleccionaron pacientes candidatos a realizar esplenopancreatecomía distal en el período comprendido entre 2007 y 2022. Se excluyeron pacientes con enfermedad sistémica. La técnica quirúrgica laparoscópica consiste en ligar los vasos cortos como primer paso, luego disecar y cortar la arteria esplénica, dejando la sección de la vena como último gesto quirúrgico. Esto evita la congestión venosa del bazo. Se analizaron variables preoperatorias, intraoperatorias y posoperatorias. Resultados: sobre un total de 155 pacientes, 90 fueron intervenidos por vía laparoscópica y 65 por vía convencional. El tiempo quirúrgico promedio fue 168 minutos. Cuando se analizó el tiempo quirúrgico en los abordajes laparoscópicos, se observó una disminución del tiempo a partir del caso número 30. La mortalidad fue del 1,12%. La incidencia de fístula pancreática total fue 41%. La necesitad de transfusión intraoperatoria ocurrió en el 10,7% de los pacientes y la tasa de conversión fue del 13,3%. Conclusión: la sistematización de la técnica de la pancreatectomía laparoscópica permite la reducción de los tiempos quirúrgicos, adquirir mayor seguridad en la disección y realizar procedimientos cada vez más complejos.

ABSTRACT Background: Laparoscopic left pancreatectomy is a high complexity procedure that should be systematized to reduce complications and operative time. Objective: To describe the results achieved with a systematized technique for laparoscopic pancreatectomy and splenectomy. Materials and methods: We selected patients who were candidates for distal pancreatectomy and splenectomy between 2007 and 2022. Patients with systemic diseases were excluded. The laparoscopic technique consists of ligating the short vessels as a first step, then dissecting and cutting the splenic artery, leaving the section of the vein as the last surgical gesture to avoid venous congestion of the spleen. Perioperative, intraoperative and postoperative variables were analyzed. Results: A total of 155 patients were analyzed, 90 underwent laparoscopy and 65 underwent conventional surgery. Mean operative time was 168 minutes The operative time in the laparoscopic approach decreased from case 30 onwards. Mortality rate was 1.12%. The incidence of pancreatic fistula was 41%. Need for intraoperative transfusion occurred in 10.7% of the patients and the conversion rate was 13.3%. Conclusion: The systematization of the technique of pancreatic laparoscopy is essential to reduce surgical times, ensure safe dissections and performe more complex procedures.

Real-World Compliance of Surgical Treatment According to the Korean Gastric Cancer Guideline 2018: Evaluation From the Nationwide Survey Data 2019 in Korea

Purpose@#This study evaluated real-world compliance with surgical treatment according to Korea's gastric cancer treatment guidelines. @*Materials and Methods@#The 2018 Korean Gastric Cancer Treatment Guidelines were evaluated using the 2019 national survey data for surgically treated gastric cancer based on postoperative pathological results in Korea. In addition, the changes in surgical treatments in 2019 were compared with those in the 2014 national survey data implemented before the publication of the guidelines in 2018. The compliance rate was evaluated according to the algorithm recommended in the 2018 Korean guidelines. @*Results@#The overall compliance rates in 2019 were 83% for gastric resection extent, 87% for lymph node dissection, 100% for surgical approach, and 83% for adjuvant chemotherapy, similar to 2014. Among patients with pathologic stages IB, II, and III disease who underwent total gastrectomy, the incidence of splenectomy was 8.08%, a practice not recommended by the guidelines. The survey findings revealed that 48.66% of the patients who underwent gastrectomy had pathological stage IV disease, which was not recommended by the 2019 guidelines. Compared to that in 2014, the rate of gastrectomy in stage IV patients was 54.53% in 2014. Compliance rates were similar across all regions of Korea, except for gastrectomy in patients with stage IV disease. @*Conclusions@#Real-world compliance with gastric cancer treatment guidelines was relatively high in Korea.

A Xiphoid Elongation Following a Trauma Laparotomy: A Case Report

Xiphoid elongation is a rare phenomenon where the xiphoid process elongates after stimuli such as surgery, physical therapy, or trauma. We report on a 47-year-old male involved in a traffic accident who went into cardiac arrest. He received ongoing cardiopulmonary resuscitation for nine minutes before recovery of cardiac rhythm, and transfer from a local hospital to the trauma center. He received management for hypotensive shock which was temporarily corrected using Resuscitative Endovascular Balloon Occlusion of the Aorta, and underwent trauma laparotomy in which ileocolic artery ligation and a splenectomy were performed. Six months later, the patient reported epigastric discomfort when he bent over. A hard, linear mass was palpated along the upper midline incision scar and a computed tomography scan showed an elongated xiphoid process (10 cm). The patient underwent surgical excision, and electrocauterization of the xiphoid process. This is a rare case of xiphoid elongation following multiple stimuli to the xiphoid process.

The mechanism of action of partial splenic artery embolization in treatment of liver cirrhosis and hypersplenism / 临床肝胆病杂志

Hypersplenism is a common complication caused by liver cirrhosis and portal hypertension, and at present, splenectomy and partial splenic artery embolization (PSE) are the main methods for the treatment of hypersplenism. Splenectomy has a marked effect in the treatment of hypersplenism and can significantly improve the clinical symptoms of patients with hypersplenism. Compared with splenectomy, PSE causes partial splenic parenchymal infarction and thus achieve similar clinical efficacy as partial splenectomy while preserving the spleen and its function. Although PSE is an effective method for the treatment of hypersplenism, there are few reports on the effect of PSE on liver fibrosis, immunity, and liver regeneration in China and globally. This article summarizes the common causes of hypersplenism, the mechanism of PSE in the treatment of hypersplenism, the therapeutic effect of different embolization methods and materials, and the effect of PSE on liver fibrosis, immunity, and liver regeneration, so as to provide a theoretical basis and new ideas for the clinical treatment of hypersplenism.

Establishment and validation of a risk prediction model for portal vein thrombosis in liver cirrhosis by nomogram / 中华消化内镜杂志

Objective:To explore the independent risk factors of portal vein thrombosis (PVT) in liver cirrhosis, and to establish and evaluate a risk prediction model for PVT in patients with cirrhosis.Methods:A total of 295 cases of cirrhosis hospitalized in Renmin Hospital of Wuhan University from December 2019 to October 2021 were divided into a modeling set ( n=207) and an internal validation set ( n=88) by the random number table. In addition, patients with cirrhosis hospitalized in Yichang Central People's Hospital, Wuhan Puren Hospital, No.2 People's Hospital of Fuyang City and People's Hospital of China Three Gorges University during the same period were collected as an external validation set ( n=92). The modeling set was divided into PVT group ( n=56) and non-PVT group ( n=151). Univariate analysis was used to preliminarily screen the related indicators of PVT, and then multivariate logistic regression analysis with forward stepwise regression was used to determine independent risk factors for PVT. A nomogram prediction model was constructed based on the independent risk factors obtained. The internal and external validation set were used to verify the predictive ability of the model. Distinction degree was used to evaluate the ability of the model to distinguish patients with or without PVT. Hosmer-Lemeshow goodness-of-fit test was used to evaluate the consistency between predicted risk and the actual risk of the model. Results:Univariate analysis showed that smoking, history of splenectomy, trans-jugular intrahepatic portosystemic shunt (TIPS), gastrointestinal bleeding and endoscopic variceal treatment, and levels of hemoglobin, alanine aminotransferase, aspartate aminotransferase and D-dimer were significantly different between the PVT group and the non-PVT group ( P<0.05). Multivariate logistic regression analysis found that smoking ( P=0.020, OR=31.21, 95% CI: 1.71-569.40), levels of D-dimer ( P=0.003, OR=1.12, 95% CI: 1.04-1.20) and hemoglobin ( P=0.039, OR=0.99, 95% CI: 0.97-1.00), history of TIPS ( P=0.011, OR=18.04, 95% CI: 1.92-169.90) and endoscopic variceal treatment ( P=0.001, OR=3.21, 95% CI: 1.59-6.50) were independent risk factors for PVT in patients with liver cirrhosis. Receiver operator characteristic (ROC) curve analysis showed that the area under the ROC curve (AUC) for the internal validation set was 0.802 (95% CI: 0.709-0.895) ( P<0.001), and the AUC for the external validation set was 0.811 (95% CI: 0.722-0.900) ( P<0.001). Both AUC were larger than 0.75. The calibration curve of Hosmer-Lemeshow goodness-of-fit test showed that the P values of both internal validation set ( χ2=3.602, P=0.891) and the external validation set ( χ2=11.025, P=0.200) were larger than 0.05. Conclusion:Smoking, history of TIPS or endoscopic variceal treatment, levels of D-dimer and hemoglobin are independent risk factors for PVT in patients with liver cirrhosis. The prediction nomogram model based on the above factors has strong predictive ability.
