ABSTRACT
ABSTRACT Lymphangiomas are rare benign tumors that mainly involve the head and neck region in pediatric patients. Lymphangiomas of the small bowel mesentery in adults are rarer. We present two cases of mesenteric lymphangioma with acute abdominal pain on presentation. Case 1: A 38-year-old female presented with abdominal pain, vomiting, fever, and difficult evacuation. On abdominal examination, she had an ill-defined, tender lump, and radiological findings raised a possibility of perforation peritonitis. Thus, exploratory laparotomy was planned. Per-operatively, a mesenteric mass was found, which, on histopathological evaluation, was found to be a mesenteric lymphangioma involving the bowel. Case 2: A 27-year-old male presented with abdominal pain and difficult evacuation. Radiological evaluation revealed a multilobulated lesion involving the mesentery and with differential diagnoses of mesenteric fibromatoses and inflammatory pseudotumor. Histopathological assessment of the resected mass revealed a lymphangioma that was limited to the mesentery. Owing to their rarity and non-specific presentation, mesenteric lymphangiomas are often misdiagnosed on clinical examination and imaging. Thus, histopathological examination is the gold standard to reach a definitive diagnosis.
ABSTRACT
ABSTRACT Introduction: The technique of open abdomen refers to a surgical procedure that intentionally involves leaving an opening in the abdominal wall. This study aimed to evaluate the clinical outcomes, mortality, and morbidity of patients undergoing open abdomen in a public hospital in Brazil and investigate associated risk factors associated with the outcome. Methods: Data from electronic medical records were collected from 2017 to 2022. The variables were used for descriptive analyses, association analysis, and survival analysis using the Kaplan-Meier curve. Results: The sample included 104 patients, with 84 presenting with acute abdomen and 20 with trauma, having highly variable ages and comorbidities. Peritonitis and the need for early reoperation were the most common indication for the procedure, each accounting for 34%, and negative pressure wound therapy was the most commonly used technique. Fistula was the most frequent complication, with the majority forming in the early days after the surgery. The number of interventions and open abdomen time obtained statistical significance in comparison with the outcome. The overall mortality rate was 62,5%. Conclusion: Despite open abdomen being a technique that can have benefits in controlling intraabdominal contamination and preventing abdominal compartment syndrome, its implementation is associated with complications. The mortality and complication rates were high in this sample. The decision to use the technique should be individualized and based on several factors, including the indications and the patient's clinical status.
RESUMO Introdução: A técnica de abdome aberto refere-se a um procedimento cirúrgico que envolve deixar deliberadamente uma abertura na parede abdominal. Este estudo teve como objetivo avaliar o desfecho clínico, mortalidade e morbidade de pacientes submetidos ao abdome aberto em um hospital público do Brasil e investigar fatores de risco associados ao desfecho. Métodos: Dados a partir de prontuários eletrônicos foram coletados de 2017 a 2022. As variáveis foram utilizadas para análises descritivas, análise de associação e de sobrevivência pela curva Kaplan-Meier. Resultados: A amostra correspondeu a 104 pacientes, sendo 84 por abdome agudo e 20 por trauma, com idade e número de comorbidades variados. A peritonite e a necessidade de reabordagem precoce foram as causas mais comuns para a indicação do procedimento, 34% cada, e a terapia de pressão negativa foi a mais utilizada neste estudo, seguindo a técnica de Barker. Fístula é a complicação mais frequente (41%), sendo que a maioria se formou nos primeiros dias após a realização da cirurgia. O número de intervenções e o tempo de abdome aberto obtiveram significância estatística na comparação com o desfecho. A mortalidade geral foi de 62,5%. Conclusão: Apesar de o abdome aberto ser uma técnica que pode trazer benefícios no controle da contaminação intra-abdominal e prevenção de síndrome compartimental abdominal, sua realização está associada a complicações. A taxa de mortalidade e morbidade foram elevadas nesta amostra. A decisão para uso da técnica deve ser individualizada e baseada em vários fatores, incluindo as indicações e o estado clínico do paciente.
ABSTRACT
El dolor abdominal de alto riesgo es una condición común en los servicios de emergencia y está asociado a una alta morbilidad y mortalidad, si no se diagnostica y trata de manera rápida y precisa. Un hombre con síntomas de cólico nefrítico se presentó en emergencia con dolor abdominal intenso y deterioro clínico. Después de una tomografía, se encontró una imagen aneurismática en la arteria iliaca común primitiva izquierda. El paciente fue trasladado a sala de operaciones para una reparación quirúrgica, pero falleció. El dolor abdominal de alto riesgo requiere un abordaje diagnóstico integral y tratamiento individualizado para prevenir complicaciones graves. El aneurisma de la arteria iliaca complicado es una causa potencialmente grave de dolor abdominal en hombres fumadores de edad avanzada con antecedentes de hipertensión y aterosclerosis.
Life-Threatening abdominal pain is a common condition in emergency departments and it is associated with high morbidity and mortality, if not promptly and accurately diagnosed and treated. A man with symptoms of renal colic presented to the emergency room with severe abdominal pain and clinical deterioration. After a CT scan, an aneurysmatic image was found in the left primitive iliac artery. The patient was taken to an operating room for surgical repair but died. Life-Threatening abdominal pain requires a comprehensive diagnostic approach and individualized treatment to prevent serious complications. The complicated iliac artery aneurysm is a potentially serious cause of abdominal pain in elderly male smokers with a history of hypertension and atherosclerosis.
ABSTRACT
El abdomen agudo comprende un amplio grupo de enfermedades con alta incidencia en la práctica quirúrgica habitual. Se presenta el caso de un paciente masculino, de 23 años, con cuadro abdominal agudo, cuyo diagnóstico preoperatorio fue compatible con una apendicitis aguda; al efectuar la laparotomía exploratoria se constató torsión primaria y segmentaria del omento mayor. Esta es una afección de difícil diagnóstico preoperatorio, generalmente diagnosticada durante el acto quirúrgico porque fácilmente se confunde con otras enfermedades del abdomen agudo quirúrgico. Lo indicado en estos pacientes es la remoción del segmento involucrado por lo que se realizó omentectomía parcial y apendicectomía complementaria; el paciente presentó una evolución clínica favorable.
Acute abdomen comprises a wide group of diseases with a high incidence in routine surgical practice. We present a 23-year-old male patient with acute abdominal symptoms, whose preoperative diagnosis was compatible with acute appendicitis; primary and segmental torsion of the greater omentum was found when performing the exploratory laparotomy. This condition is difficult to diagnose preoperatively; it is generally evident during surgery because it is confused with other diseases of the acute surgical abdomen. The removal of the involved segment is indicated in these patients that is why partial omentectomy and complementary appendectomy were performed; the patient had a favourable clinical evolution.

SUMMARY OBJECTIVE: The aim of this study was to evaluate the diagnostic performance of diffusion-weighted imaging compared to non-contrast magnetic resonance imaging in the differential diagnosis of acute appendicitis in pregnant patients. METHODS: A total of 72 pregnant patients with the suspicion of acute appendicitis who underwent magnetic resonance imaging combined with diffusion-weighted imaging examinations were enrolled in this retrospective study. Magnetic resonance imaging images (non-contrast and diffusion-weighted imaging sequences) were evaluated. Moreover, apparent diffusion coefficient ratios were estimated. The diagnostic performances of magnetic resonance imaging and diffusion-weighted imaging findings were statistically analyzed on the basis of surgical and follow-up results. RESULTS: Of 72 pregnant patients, 10 (14%) had acute appendicitis on magnetic resonance imaging and diffusion-weighted imaging. Among 10 patients with acute appendicitis, three (3/10) had perforation. diffusion-weighted imaging findings had higher sensitivity (90 versus 60%), negative predictive value (98.41 versus 93.94%), and accuracy (98.61 versus 94.44%) ratios compared to non-contrast magnetic resonance imaging in the diagnosis of acute appendicitis. There was one false-negative result on diffusion-weighted imaging. Diffusion restriction facilitated the detection of appendicitis. The apparent diffusion coefficient ratios were lower in acute appendicitis than in the normal appendix (0.70±0.19 versus 0.96±0.16) (p<0.05). CONCLUSION: With a shorter scan time and higher diagnostic accuracy, diffusion-weighted imaging can be useful for the early diagnosis of acute appendicitis and for planning appropriate management.
ABSTRACT
The acute abdomen of hernia mainly refers to an incarcerated hernia, which is a common acute abdomen in clinic. CT plays an important role in the diagnosis of incarcerated hernia. If incarcerated hernia is not handled timely and correctly, it may further develop into strangulated hernia, leading to intestinal necrosis, perforation and even endangering the patient′s life. Manual reduction can be attempted for patients with low risk of reduction, and active surgery should be performed for patients with unsuccessful reduction or high risk of manipulative reduction. More and more evidence shows that laparoscopic minimally invasive treatment of acute incarcerated hernia has practical clinical efficacy and fewer postoperative complications. The use of mesh in incarcerated hernia surgery has also been shown to be safe and feasible, as long as it is properly selected, even in incarcerated hernia repair during enterectomy, mesh does not increase the risk of infection in the surgical area and greatly reduces the likelihood of postoperative recurrence. At the same time, the concept of accelerated rehabilitation surgery was used to strengthen perioperative management, reduce complications and promote rehabilitation of patients.
ABSTRACT
ABSTRACT BACKGROUND: Clinical features and outcomes of patients admitted to the intensive care unit due to acute abdomen are important to be investigated. AIMS: To evaluate the outcomes of critically ill subjects with acute abdomen according to etiology, comorbidity and severity. METHODS: Outcomes of 1,523 patients (878 women, mean age 66±18 years) consecutively admitted to a specialized gastrointestinal intensive care unit with different causes of acute abdomen from January 2012 to December 2019, were retrospectively evaluated according to etiology, comorbidity and severity. RESULTS: The most common causes of acute abdomen were obstructive and inflammatory, particularly large bowel obstruction (27%), small bowel obstruction (18%) and acute pancreatitis (17%). Overall mortality was 13%. Surgery was required in 34% of patients. Median length of stay in the hospital was 9 [1-101] days. On univariate analysis mortality was significantly associated with age, APACHE II, Charlson comorbidity index, requirement for surgery and malignancy (p<0.0001), but only APACHE II, Charlson comorbidity index and surgical interventional remained significant on multivariate analysis. CONCLUSIONS: Critically ill patients admitted to the intensive care unit with acute abdomen constitute a heterogeneous group of subjects with different prognosis. Mortality is more related to the severity of the disease, comorbidity and need for surgery than to the etiology of the acute abdomen.
RESUMO RACIONAL: As características clínicas e os desfechos dos pacientes internados na unidade de terapia intensiva devido ao abdômen agudo são importantes serem investigados. OBJETIVOS: Avaliar os desfechos de indivíduos gravemente doentes com abdômen agudo de acordo com etiologia, gravidade e comorbidade. MÉTODOS: Os desfechos de 1.523 pacientes (878 mulheres, média de idade 66±18 anos) que foram previamente admitidos em uma unidade de terapia intensiva especializada em doenças gastrointestinais, com diferentes causas de abdômen agudo entre janeiro de 2012 e dezembro de 2019, foram avaliados retrospectivamente segundo etiologia, comorbidade e gravidade. RESULTADOS: As causas mais comuns de abdômen agudo foram obstrutivas e inflamatórias, com destaque para obstrução em colon (27%), em intestino delgado (18%) e pancreatite aguda (17%). A mortalidade geral foi de 13%. A cirurgia foi necessária em 34%. A média de permanência no hospital foi de 9 [1-101] dias. Na análise univariada a mortalidade foi significativamente associada à idade, APACHE II, índice de comorbidade de Charlson, necessidade de abordagem cirúrgica e presença de malignidade (p<0,0001), mas apenas APACHE II, índice de comorbidade de Charlson e intervenção cirúrgica permaneceram significativos na análise multivariada. CONCLUSÕES: Pacientes internados na unidade de terapia intensiva com abdômen agudo constituem um grupo heterogêneo de indivíduos com prognóstico diferente. A mortalidade está mais relacionada com a gravidade da doença, comorbidade e necessidade de cirurgia do que com a etiologia do abdome agudo.
ABSTRACT
La duodenitis eosinofílica tiene una prevalencia entre 5,1 a 8,2 por 100000 personas. Se desconocen los mecanismos moleculares subyacentes de la enfermedad, pero la hipersensibilidad (alergias estacionales y alimentarias) juega un papel importante en su patogénesis, la predisposición alérgica se encuentra en el 25-35% de los casos. El diagnóstico incluye manifestaciones clínicas, hallazgos imagenológicos y evidencia histológica de infiltración eosinofílica >20 eosinófilos por campo de alto poder. Realizamos un informe de caso clínico y revisión de literatura. Hombre de 25 años con vitíligo que consulta a urgencias refiriendo síntomas de dispepsia, vómitos y dolor abdominal de máxima intensidad, en el examen médico se localiza dolor abdominal superior, con paraclínicos normales excepto un recuento de eosinófilos >2000 células/ul, la ecografía abdominal fue normal, la endoscopia superior reveló pangastritis eritematosa y duodenitis con pliegues rígidos y engrosados, la colonoscopia mostró hemorroides grado I. Coproscópico seriado negativo para parásitos, IgE total, IgA e IgG en rango normal, se reportó IgG positivo a Toxoplasma gondii, perfil de autoinmunidad negativo. En los siguientes 4 días aumenta el dolor abdominal y el recuento de eosinófilos, con endoscopia control y tomografía abdomino-pélvica contrastada que muestran duodeno edematizado con reflujo biliar severo, reporte histopatológico con duodenitis crónica atrófica y con pruebas para alergenos alimentarios positivo a cereales (centeno, soja, cebada), Manihot esculenta, plátano verde, tomate, leche de vaca, naranja y piña. Se indicó dieta restrictiva e inhibidor de la bomba de protones (pantoprazol), control ambulatorio a los 45 días de resolución de los síntomas con recuento de eosinófilos en sangre normal. Se presenta un caso de duodenitis eosinofílica relacionada con alergia alimentaria con mecanismos IgE independientes en un varón joven con vitíligo, que debutó con cuadro clínico inusual de dolor visceral agudo y reflujo biliar, que se resolvió con dieta de eliminación y pantoprazol sin uso de corticoides.
Background: Eosinophilic duodenitis has a prevalence of 5.1 to 8.2 per 100000 persons. The underlying molecular mechanisms are unknown, but hypersensitivity (seasonal and food allergies, asthma, eczema) response plays a major role in its pathogenesis, allergic predisposition can be found up-to 25-35% of cases. The diagnosis includes clinical manifestation, imaging findings and histological evidence of eosinophilic infiltration >20 eosinophils per high-power field. This is a clinical case report. a 25-years old man with vitiligo consult to emergency department referring dyspepsia symptoms, vomiting and abdominal pain of maximal intensity, in the medical exam upper abdominal pain was found, blood laboratories were unremarkable except a high net eosinophil-count >2000 cells/ul, abdominal ultrasound were normal, upper endoscopy revealed duodenitis with rigid and thickened folds, colonoscopy show hemorrhoids grade I. Coproscopy exam was negative for parasites, total IgE, IgA and IgG were in normal range, a positive IgG to Toxoplasma gondii was reported, autoimmunity panel was negative. In the following 4 days the abdominal pain and eosinophils count increase, a new abdomin-pelvic tomography was done showing thickened duodenum with a new endoscopy showing marked edema in duodenum with severe biliary reflux with biopsies describing an atrophic chronic duodenitis. Allergy tests -skin prick and patch tests- were done resulting positive to cereals (rye, soy, barley), Manihot esculenta, green banana, tomato, cow milk, orange and pineapple. A restrictive diet and protons pump inhibitor was indicated, ambulatory control at 45 days after show symptoms resolution with a normal blood eosinophils count. Here is reported a case of eosinophilic duodenitis related to food allergy in a young man with vitiligo debuting with an unusual clinical presentation of acute visceral pain and biliary reflux which resolved with elimination diet and pantoprazole without use of corticoids, with both, IgE and non-IgE mechanisms playing important roles explaining food sensitization.
ABSTRACT
RESUMEN Se presenta el caso de un hombre de 37 años sin antecedentes de dolor abdominal, o padecimiento de alguna enfermedad, que recibió un golpe directo con objeto romo (bate de béisbol) en el cuadrante inferior derecho del abdomen. Asistió a consulta con dolor abdominal selectivo en fosa ilíaca derecha, de aproximadamente 29 horas de evolución, que comenzó después de un trauma abdominal cerrado. Al examen físico se constata signo de Blumberg positivo, punto de McBurney doloroso con hiperestesia cutánea y cierto grado de defensa muscular. En los exámenes complementarios se comprueba leucocitosis y predominio de neutrófilos, con desviación a la izquierda. Se decidió realizar laparotomía exploratoria y se constató en el transoperatorio apendicitis aguda flegmonosa. La etiología traumática en la apendicitis aguda es un diagnóstico por exclusión que debe ser considerado en condiciones específicas.
ABSTRACT We present a 37 year-old man with no antecedents of abdominal pain, or suffering from other illnesses who received a direct blow with a blunt object (baseball bat) in the right lower quadrant of the abdomen. The patient was seen in consultation with a selective abdominal pain in his right iliac fossa, with approximately 29 hours of evolution that began after a closed abdominal trauma. A positive Blumberg sign, a painful McBurney's point with cutaneous hyperesthesia and certain grade of muscular defense were verified on physical exam. Leukocytosis and prevalence of neutrophils with left deviation were proven on complementary exams. An exploratory laparotomy was decided and a phlegmonous acute appendicitis was verified during the periprocedural period. Traumatic etiology in acute appendicitis is a diagnosis for exclusion that should be considered under specific conditions.

Appendicitis/diagnosis , Abdomen, AcuteABSTRACT
Ectopic pregnancy is one of the most common acute abdominal diseases in gynecology. A ruptured ectopic pregnancy can lead to hemorrhagic shock, which is life-threatening. Therefore, early diagnosis and early treatment are extremely critical for preserving fertility and achieving good prognosis in patients with ectopic pregnancy. The available diagnostic methods of ectopic pregnancy include laboratory tests such as progesterone test, human chorionic gonadotropin test and ultrasound examination. Ultrasound examination can help determine the location of uterine and adnexal masses, gestational sacs, and germ, all of which are directly related to the final diagnosis regarding ectopic pregnancy. Ultrasound examination includes abdominal ultrasound and transvaginal ultrasound. Transvaginal ultrasound accesses to the focal tissue closer than abdominal ultrasound, and it does not require a full bladder. These advantages make clinical practice of transvaginal ultrasound easier for both physicians and patients. However, application of transvaginal ultrasound in the diagnosis of ectopic pregnancy requires further investigation to guide the early diagnosis and treatment of ectopic pregnancy. .
