RESUMO
Introdução: Os traumas abdominais representam notável importância dentre as causas predominantes de morbi-mortalidade no mundo. Em se tratando de óbitos relacionados a essas lesões, estão na categoria de causas externas, as quais no Brasil representam a segunda causa geral de mortalidade, principalmente na população em idade ativa. Notadamente, traumas estão fortemente relacionados a acidentes automobilísticos, cujas taxas vêm crescendo nos últimos anos. Neles, ocorrem os politraumas, cuja região abdominal é inclusa de forma prevalente. Objetivo: a presente pesquisa tem como objetivo apresentar o perfil de óbitos os quais sejam associados a trauma abdominal e submetido ao Instituto Médico-Legal, entre os anos de 2019 até 2021. Metodologia: estudo retrospectivo, do tipo transversal, de caráter fundamentalmente quantitativo, no qual foram avaliados os laudos de óbitos decorrentes de trauma abdominal necropsiados no IML de Toledo (PR), no período de 2019 a 2021. Foram avaliadas as variáveis sexo, idade, tipo de lesão, circunstância dos óbitos e órgão mais acometido. Resultados e discussão: dos 916 óbitos trazidos à Polícia Científica de Toledo (PR) advindos de causas externas, os inclusos dentre os traumas abdominais representaram um percentual de 51,05% (n=462), no período de 2019 a 2021. Observou-se maior prevalência de óbitos por acidentes automobilísticos (68,61%), cuja causa principal foi o politrauma (37,45%). O sexo masculino fora o mais prevalente, com 84,85% (n=392), cuja faixa etária teve concentração entre os 18 aos 29 anos. Os órgãos mais lesionados foram o fígado (69,31%) e o baço (33,66%). Considerações finais: nesta amostra houve predominância de óbitos por acidentes, principalmente associados ao trauma contuso, em homens na faixa entre 18 e 29 anos, cujo órgão mais lesado fora o fígado. O conhecimento acerca do perfil de óbitos é uma importante ferramenta epidemiológica frente a possíveis intervenções, além de servir como fonte estatística para outros trabalhos do âmbito médico-legal.
Introduction: Trauma represents a notable importance among the predominant causes of morbidity and mortality in the world. When it comes to deaths related to these injuries, they are in the category of external causes, since in Brazil they represent the second general cause of mortality, especially in the working-age population. Notably, traumas are strongly related to car accidents, whose rates have been increasing in recent years. In them, polytraumas occur, whose abdominal region is prevalently included. Objective: this research aims to present the profile of deaths which are associated with abdominal trauma and hospitalized at the Instituto Médico-Legal, between the years 2019 to 2021. Methodology: retrospective, cross-sectional study, fundamentally quantitative, in which the reports of deaths resulting from abdominal trauma necropsied at the IML of Toledo (PR), from 2019 to 2021, were evaluated. The variables were gender, age, type of injury, injuries of the deaths and most affected organ. Results and removal: Of the 916 deaths brought to the Scientific Police of Toledo (PR) from external causes, those included among abdominal traumas represented a percentage of 51.05% (n=462), in the period from 2019 to 2021. there was a higher prevalence of deaths from car accidents (68,61%), whose main cause was polytrauma (37.45%). Males were the most prevalent, with 84.85% (n=392), whose age group was concentrated between 18 and 29 years. The most injured organs were the liver (69.31%) and the spleen (33.66%). Final considerations: in this sample there was a predominance of deaths from accidents, mainly associated with blunt trauma, in men aged between 18 and 29 whose most injured organ outside the liver. Knowledge about the profile of deaths is an important epidemiological tool in the face of possible interventions, in addition to serving as a statistical source for other studies in the medical-legal field.

RESUMO
Introdução: O estudo explora a cirurgia de contorno corporal em pacientes submetidos a cirurgias bariátricas. Nos últimos anos, esse tipo de intervenção cirúrgica ganhou destaque devido ao aumento na busca por procedimentos reparadores após significativa perda de peso. O texto enfatiza a importância da flancoplastia, técnica que visa melhorar o contorno corporal. Métodos: Foi realizada revisão da literatura para elucidação da anatomia da gordura profunda da fáscia toracolombar, e feito um paralelo com a técnica de flancoplastia utilizada em nosso serviço em pacientes pós-bariátricos submetidos a abdominoplastia 360° ou 270° no Hospital Daher Lago Sul, em Brasília- DF. Resultados: A lipoaspiração profunda dos flancos, muitas vezes necessária em cirurgias de contorno corporal, pode não ser suficiente para retirar a gordura profunda à fáscia toracolombar e durante esse procedimento observa-se risco aumentado de lesões retroperitoneais. No entanto, a flancoplastia, que envolve a ressecção da gordura profunda à fáscia toracolombar, demonstrou proporcionar resultados satisfatórios e minimizar esses riscos. Conclusão: O estudo enfoca a importância do conhecimento anatômico preciso, destacando a relevância da flancoplastia como uma técnica valiosa para melhorar os resultados estéticos e reduzir complicações em pacientes pós-bariátricos, complementando a cirurgia bariátrica e melhorando a qualidade de vida do paciente.
Introduction: The study explores body contouring surgery in patients undergoing bariatric surgery. In recent years, this type of surgical intervention has gained prominence due to the increase in the search for reparative procedures after significant weight loss. The text emphasizes the importance of flankplasty, a technique that aims to improve body contour. Methods: A literature review was carried out to elucidate the anatomy of the deep fat of the thoracolumbar fascia, and a parallel was made with the flankplasty technique used in our service in post-bariatric patients undergoing 360° or 270° abdominoplasty at Daher Lago Sul Hospital, in Brasília-DF. Results: Deep liposuction of the flanks, often necessary in body contouring surgeries, may not be sufficient to remove fat deep into the thoracolumbar fascia and during this procedure, there is an increased risk of retroperitoneal injuries. However, flankplasty, which involves resection of fat deep into the thoracolumbar fascia, has been shown to provide satisfactory results and minimize these risks. Conclusion: The study focuses on the importance of precise anatomical knowledge, highlighting the relevance of flankplasty as a valuable technique to improve aesthetic results and reduce complications in post-bariatric patients, complementing bariatric surgery and improving the patient's quality of life.
RESUMO
Introducción. El dolor abdominal es uno de los principales motivos de admisión a urgencias y una de las causas más frecuentes es la enfermedad diverticular, que aumenta su prevalencia en el adulto mayor. Sin embargo, la diverticulitis del intestino delgado es una enfermedad infrecuente y en la mayoría de casos es asintomática. No obstante, la perforación de un divertículo intestinal es una complicación común de esta patología, por lo que debe ser considerado como un diagnóstico diferencial de abdomen agudo en este grupo poblacional. Caso clínico. Paciente masculino de 71 años, quien consultó por dolor abdominal de inicio súbito, con signos de irritación peritoneal al examen físico. Dado su deterioro hemodinámico fue llevado a cirugía y en la laparotomía exploratoria se halló una diverticulitis aguda perforada de yeyuno e íleon distal. Resultados. El paciente cursó con una adecuada evolución postoperatoria, sin reingresos. Conclusión. La diverticulitis aguda yeyuno-ileal es una causa importante, pero no frecuente de perforación intestinal. Hay muy pocos casos reportados en la literatura, lo que la convierte en un reto diagnóstico para el médico de urgencias y el cirujano general. No obstante, debe ser considerado como un diagnóstico diferencial en adultos mayores con abdomen agudo.
Introduction. Abdominal pain is one of the main reasons for admission to the emergency room and one of the most frequent causes is diverticular disease, which increases its prevalence in the elderly. However, diverticulitis of the small bowel is rare and in most cases asymptomatic. However, perforation of an intestinal diverticulum is a common complication of this pathology and should be considered as a differential diagnosis of acute abdomen in this population group. Clinical case. A71-year-old male patient presented with abdominal pain of sudden onset, with signs of peritoneal irritation. Given his hemodynamic deterioration, he was taken to surgery and in the exploratory laparotomy an acute perforated diverticulitis of the jejunum and distal ileum was found. Results. The patient had an adequate postoperative evolution, without readmissions. Conclusion. Acute jejuno-ileal diverticulitis is an important but uncommon cause of intestinal perforation. There are very few cases reported in the literature, which makes it a diagnostic challenge for the emergency physician and general surgeon. However, it should be considered as a differential diagnosis in older adults with acute abdomen.

Acute abdominal pathologies can cause electrocardiogram (ECG) changes mimicking an acute coronary syndrome (ACS), resulting in diagnostic uncertainty and delay. We report a 65-year-old male with multiple risk factors for ACS who presented with four hours of progressive epigastric and chest pain that resolved in the emergency department. ECG findings were concerning for new deeply inverted T-waves with normal troponins, raising concerns for Wellens Syndrome. Emergent heart catheterization was negative but abdominal computed tomography angiography showed occlusion of the superior mesenteric vessels. Subsequent exploratory laparotomy revealed a small bowel volvulus with extensive necrosis, resulting in a 430 cm resection.
RESUMO
An arcuate line hernia is a generally asymptomatic, ascending protrusion of intraperitoneal structures over the linea arcuata. Arcuate line herniae are scarcely reported in the literature. Only a few publications were found. No clear descriptions of the techniques for repair have been published either. We aim to provide diagnostic images and illustrate our method to repair this hernia.
RESUMO
We describe cases of intestinal failure wherein inpatient admission was critical toward enteral autonomy. We performed a retrospective chart review of 6 children with long-term parenteral nutrition dependence who were weaned from parenteral nutrition after admission. Admissions included feeding and medication titration, interdisciplinary care, and a home parenteral nutrition team consultation.
RESUMO
SUMMARY: Endometriosis, defined as the presence of endometrial glands and stroma outside the uterine cavity, is a chronic inflammatory condition that affects between 8 % and 44 % of women of reproductive age. Occasionally it presents as a sensitive mass in the abdominal wall, in relation to a surgical scar. On the other hand, in the most severe stage of endometriosis, intestinal involvement is common, and endometriotic disease of the appendix may be present even in appendices with macroscopically normal appearance. Simultaneous affectation of both locations is very rare. Nevertheless, treatment of choice is the excision of both lesions with safety margins. The aim of this manuscript was to report a case of simultaneous deep endometriosis affecting the total abdominal wall and vermiform appendix, resected in a single surgical procedure, which subsequently required abdominal wall repair with mesh plasty. Since desmoid tumors and endometriosis share similar clinical signs and unspecific imaging exams, both options should be considered in case of abdominal wall mass in female patients of childbearing age, especially if they have a history of uterine-related surgery.
La endometriosis se define como la presencia de glándulas endometriales y estroma fuera del útero. Es una afección crónica que afecta entre el 8 % y el 44 % de las mujeres en edad reproductiva. Ocasionalmente se presenta como una masa sensible en la pared abdominal, en relación con una cicatriz quirúrgica. Por otro lado, en su estadio más grave de la endometriosis, la afectación intestinal es común y puede afectar al apéndice, pudiendo estar presente incluso en apéndices de apariencia macroscópicamente normal. La afectación de ambas localizaciones simultáneamente es muy infrecuente. Sin embargo, el tratamiento de ambas lesiones es su exéresis quirúrgica con márgenes de seguridad. El objetivo de este manuscrito fue reportar un caso de endometriosis profunda simultánea que afectaba la pared abdominal total y el apéndice vermiforme, las que fueron resecadas en un solo tiempo quirúrgico, incluyendo posteriormente reparación de la pared abdominal con uso de malla. Dado que los tumores desmoides y la endometriosis comparten signos clínicos similares y exámenes de imágenes inespecíficos, se deben considerar ambas opciones en caso de masas en la pared abdominal de mujeres en edad fértil, especialmente si tienen antecedentes de cirugía relacionada con el útero.

Significance: The laparotomy is a common surgical procedure with a wide range of indications. Ideally, once the goals of surgery were achieved, the incision edges could then be approximated and the abdomen primarily closed. However, in some circumstances, it may be impossible to achieve primary closure, and instead the abdomen is intentionally left open. This review discusses the indications and objectives for the open abdomen (OA), summarizes the most common techniques for temporary abdominal closure, and illustrates treatment algorithms grounded in the current recommendations from specialty experts. Recent Advances: Still a relatively young technique, multiple strategies, and technologies have emerged to manage the OA. So too have the recommendations evolved, based on updated classifications that take wound characteristics into account. Recent studies have also brought greater clarity on recommendations for managing infection and malnutrition to support improved clinical outcomes. Critical Issues: The status of the OA can change rapidly depending on the patient's condition, the wound quality, and many other factors. Thus, there is a significant need for comprehensive treatment strategies that can be adapted to these developing circumstances. Future Directions: Treatment recommendations should be continuously updated as new technologies are introduced and old techniques fall out of use.

BACKGROUND: The leading cause of death in older people is cardiovascular diseases. Several studies have found that neck circumference (NC) is a simple anthropometric marker associated with adiposity. The aim of this study is to estimate and validate NC cut-off points as adiposity markers and analyze their association with cardiovascular and chronic metabolic diseases in older people. METHODS: A cross-sectional study in 358 non-disabled, community-dwelling older people (71.7 ± 3.9 years) living in Santiago de Chile and participating in the HTSMayor study was conducted. Measurements of body composition and cardiovascular risks were evaluated. Receiver operating characteristic (ROC) curves and multiple logistic regression models were used to evaluate the association of NC with cardiovascular and chronic metabolic diseases. NC cut-off points were obtained to predict obesity, abdominal obesity, and adiposity. RESULTS: The best performance values of neck circumference relative to obesity and adiposity were obtained with respect to abdominal obesity (40.6 cm in men and 34.2 cm in women). Higher NC values were associated with a higher area under the curve (AUC) for men and women (men: AUC = 0.84; women: AUC = 0.86). NC was significantly associated with a higher risk for diabetes mellitus (OR = 1.95), hypertension (OR = 2.42), acute myocardial infarction (OR = 4.36), and comorbidities (OR = 2.01), and a lower risk for sarcopenia (OR = 0.35). CONCLUSIONS: This study shows that NC is a useful tool for detecting abdominal obesity, obesity, and adiposity in older people and that a higher NC increases the risk of chronic diseases.
RESUMO
OBJECTIVE: Abdominal Aortic Aneurysms (AAA) growth remains a process not fully understood. The objective of this study was to analyze risk factors associated with changes in AAA diameter in a Mexican cohort. METHODS: An observational study in which we analyzed the entirely of patients in which an AAA was reported in a Computed Tomography (CT) study from 2014 to 2021 who had a follow-up CT. We divided them by groups depending on the diagnosis of type 2 diabetic mellitus and pharmacological history (diabetic vs non-diabetic, metformin vs non-metformin intake and statin vs non-statin intake). We compared pre and post follow-up AAA diameters using paired t-tests. A multivariate analysis was performed in order to identify independent variables associated with an increased growth rate. Statistical analysis was performed on Stata 17. RESULTS: During the studied period 72 (39.77%) patients had a follow-up CT. Mean age was 75 years (±9.05) and 52 (72.22%) were men. When comparing infra-renal largest diameter through time based on metformin intake, a significant difference was found only in the metformin non-intake group (42.05 ± 12.54 vs45.34 ± 12.06 [P = 0.02]), in contrast the metformin intake group measures were non-significantly different (36.13 ± 7.04 vs 37.00 ± 4.51; P = 0.57) through follow-up. In the multivariate analysis AAA largest diameter at diagnosis correlated with significantly increased growth rate (coeff = 0.06, P < 0.05). CONCLUSIONS: AAA diameters appear to change through time in a non-linear pattern influenced by different epidemiological and clinical factors. Metformin intake appears to promote a stability in AAA diameter growth in our studied population.

OBJECTIVE: To examine the relationship between the age-adjusted Charlson comorbidity index (A-CCI) with body composition and overall survival in patients newly diagnosed with colorectal cancer (CRC). RESEARCH METHODS AND PROCEDURES: In this cohort study, patients (≥ 18 years old) with CRC were followed for 36 months. Computed tomography images of the third lumbar were analyzed to determine body composition, including skeletal muscle area (SMA), skeletal muscle index (SMI), skeletal muscle radiodensity (SMD), visceral adipose tissue (VAT), and subcutaneous adipose tissue (SAT). Phenotypes based on comorbidity burden assessed by A-CCI and body composition parameters were established. RESULTS: A total of 436 participants were included, 50% male, with a mean age of 61 ± 13.2 years. Approximately half of the patients (50.4%) had no comorbidity, and the A-CCI median score was 4 (interquartile range: 3-6). A higher A-CCI score was a risk factor for 36-month mortality (HR = 3.59, 95% CI = 2.17-5.95). Low SMA and low SMD were associated with a higher A-CCI. All abnormal phenotypes (high A-CCI and low SMA; high A-CCI and low SMD; high A-CCI and high VAT) were independently associated with higher 36-month mortality hazard (adjusted HR 5.12, 95% CI 2.73-9.57; adjusted HR 4.58, 95% CI 2.37-8.85; and adjusted HR 2.36, 95% CI 1.07-5.22, respectively). CONCLUSION: The coexistence of comorbidity burden and abnormal body composition phenotypes, such as alterations in muscle or fat compartments, may pose an additional risk of mortality in patients newly diagnosed with CRC. Early assessment and management of these phenotypes could be crucial in optimizing outcomes in such patients.

Background: Kawasaki disease (KD), an acute febrile illness and systemic vasculitis, is the leading cause of acquired heart disease in children in industrialized countries. KD leads to the development of coronary artery aneurysms (CAA) in affected children, which may persist for months and even years after the acute phase of the disease. There is an unmet need to characterize the immune and pathological mechanisms of the long-term complications of KD. Methods: We examined cardiovascular complications in the Lactobacillus casei cell wall extract (LCWE) mouse model of KD-like vasculitis over 4 months. The long-term immune, pathological, and functional changes occurring in cardiovascular lesions were characterized by histological examination, flow cytometric analysis, immunofluorescent staining of cardiovascular tissues, and transthoracic echocardiogram. Results: CAA and abdominal aorta dilations were detected up to 16 weeks following LCWE injection and initiation of acute vasculitis. We observed alterations in the composition of circulating immune cell profiles, such as increased monocyte frequencies in the acute phase of the disease and higher counts of neutrophils. We determined a positive correlation between circulating neutrophil and inflammatory monocyte counts and the severity of cardiovascular lesions early after LCWE injection. LCWE-induced KD-like vasculitis was associated with myocarditis and myocardial dysfunction, characterized by diminished ejection fraction and left ventricular remodeling, which worsened over time. We observed extensive fibrosis within the inflamed cardiac tissue early in the disease and myocardial fibrosis in later stages. Conclusion: Our findings indicate that increased circulating neutrophil counts in the acute phase are a reliable predictor of cardiovascular inflammation severity in LCWE-injected mice. Furthermore, long-term cardiac complications stemming from inflammatory cell infiltrations in the aortic root and coronary arteries, myocardial dysfunction, and myocardial fibrosis persist over long periods and are still detected up to 16 weeks after LCWE injection.

Mycotic aneurysms of the iliac and other large arteries are rare and are associated with increased morbidity and mortality. Treatment of mycotic aneurysms usually requires modification of the surgical technique done for cases of degenerative or atherosclerotic aneurysms. Degenerative and atherosclerotic fusiform aneurysms are usually managed with aneurysmorrhaphy using a prosthetic graft, which however is not ideal for mycotic aneurysms. Avoidance of prosthetic material at the site of mycotic aneurysm is a better option with higher chances of resolution of infection and favorable patient outcome.

Testicular ischemia is one of the most rarely reported complications of endovascular abdominal aortic aneurysm repair (EVAR). Although the pathogenesis remains unclear, thromboembolic events in the setting of testicular artery origin occlusion by the stent graft and poor baseline collateral testicular circulation are presumed causes. A 73-year-old man developed acute right testicular infarction 3 days after EVAR, requiring orchiectomy. This case emphasizes the importance of recognizing and evaluating testicular pain after EVAR and counseling patients on this possible EVAR complication.
RESUMO
Introducción. Las complicaciones posteriores a la reparación endovascular de aneurisma (EVAR) pueden resolverse con técnicas endovasculares. Sin embargo, cuando está indicada, la explantación de una endoprótesis es un procedimiento complejo, que se asocia a lesiones vasculares o viscerales, con alta morbimortalidad, en pacientes con edad avanzada y múltiples comorbilidades, y por lo tanto, alto riesgo quirúrgico. No existen dispositivos producidos por la industria para explantar las endoprótesis aórticas, por lo que el objetivo de este trabajo fue desarrollar un dispositivo para la explantación de endoprótesis aórticas. Métodos. Se llevó a cabo un estudio experimental, en fase preclínica, para desarrollar un dispositivo para la explantación de endoprótesis aórticas, con pruebas en modelos 3D y en un modelo animal porcino cadavérico. Resultados. Es factible desarrollar un modelo experimental de un nuevo dispositivo para explantar endoprótesis aórticas, denominado explantador de Cabrera, y comprobar su funcionamiento en un modelo animal cadavérico. El uso del explantador de Cabrera limitó el daño de la pared aórtica por parte de la endoprótesis en un 100 % al momento de su explantación en un modelo experimental ex vivo. Conclusión. Usando una jeringa septo, el explantador de Cabrera es superior a la técnica estándar de explantación de una endoprótesis al limitar la lesión de la pared aórtica, al colapsar y liberar los ganchos de fijación suprarrenal de forma controlada y segura al interior de la luz aórtica y, posteriormente, extraerla de forma rápida y efectiva, conservando la mayor cantidad de aorta sana para la posterior reconstrucción aorto-ilíaca.
Introduction. Complications after endovascular aneurysm repair (EVAR) can be resolved with endovascular techniques; however, when indicated, stent explantation is a complex procedure, which is associated with vascular or visceral injuries, with high morbidity and mortality in patients, with advanced age and multiple comorbidities, and therefore high surgical risk. There are no devices produced by the industry to explant aortic endoprostheses, so the objective of this work was to develop a device for the explantation of aortic endoprostheses. Methods. An experimental study was carried out, in the preclinical phase, to develop a device for the explantation of aortic endoprostheses, with tests in 3D models and in a cadaveric porcine animal model. Results. It is feasible to develop an experimental model of a new device for explanting aortic endoprostheses, called Cabrera explanter, and verify its operation in a cadaveric animal model. The use of the Cabrera explanter limited damage to the aortic wall by the endoprosthesis by 100% at the time of explantation in an ex vivo experimental model. Conclusions. Using a septum syringe, the Cabrera explanter is superior to the standard stent explantation technique by limiting injury to the aortic wall, collapsing and releasing the adrenal fixation hooks in a controlled and safe manner into the aortic lumen, and subsequently, extract it quickly and effectively, preserving the greatest amount of healthy aorta for the subsequent aorto-iliac reconstruction.

Introducción. El síndrome de la arteria mesentérica superior, también conocido como síndrome de Wilkie, es una entidad infrecuente en la que una reducción del ángulo o espacio aorto-mesentérico determina una compresión extrínseca con obstrucción del tercio distal del duodeno, demostrando síntomas y signos característicos de obstrucción intestinal. El pilar del tratamiento es el manejo médico conservador con repleción nutricional, con el objetivo de aumentar el grosor de la grasa retroperitoneal y con esto resolver la compresión duodenal. Caso clínico. Paciente de 16 años, con un curso crónico marcado por dolor abdominal, estreñimiento, distensión, pirosis y pérdida de peso. Inicialmente se trató como una enfermedad ácido-péptica, con pobre mejoría, por lo que se realizaron estudios imagenológicos con lo que se documentó una disminución del ángulo aortomesentérico. Resultado. Se instauró un manejo médico con un protocolo de repleción nutricional por vía oral, para lograr ganancia de peso y evitar la cirugía. Conclusión. Con base a los síntomas y hallazgos en imágenes diagnósticas se hizo el diagnóstico de síndrome de la arteria mesentérica superior, que es una causa de obstrucción intestinal con muy baja incidencia. Su presentación clínica incluye gran variedad de síntomas, entre los que destaca el dolor abdominal y la pérdida de peso. Es frecuente la confusión con otras enfermedades más frecuentes, como enfermedad ácido-péptica, reflujo gastrointestinal y malabsorción. Su diagnóstico requiere un alto índice de sospecha, por lo que es importante conocer esta entidad y considerarla en el estudio de pacientes con los síntomas mencionados.
Introduction. Superior mesenteric artery syndrome, also known as Wilkie syndrome, is a rare entity in which a reduction in the aorto-mesenteric angle or space determines extrinsic compression with obstruction of the distal third of the duodenum, demonstrating characteristic symptoms and signs of intestinal obstruction. The mainstay of treatment is conservative medical management with nutritional repletion, with the aim of increasing the thickness of the retroperitoneal fat and thereby resolving duodenal compression. Clinical case. A 16-year-old patient, with a chronic course marked by abdominal pain, constipation, bloating, heartburn and weight loss. Initially was treated as an acid-peptic disease, with poor improvement. Imaging studies were performed, which documented a decrease in the aorto-mesenteric angle. Conclusion. Based on the symptoms and findings on diagnostic images, the diagnosis of superior mesenteric artery syndrome was made, which is a cause of intestinal obstruction with a very low incidence. Its clinical presentation includes a wide variety of symptoms, among which abdominal pain and weight loss stand out. Confusion with other more common diseases is common, such as acid-peptic disease, gastrointestinal reflux and malabsorption. Its diagnosis requires a high index of suspicion, so it is important to know this entity and consider it in the study of patients with the aforementioned symptoms.

El presente estudio es una comparación del dolor abdominal producido por trastornos gastrointestinales, aliviado por Ageratina ligustrina , entre los grupos maya Tzeltal, Tzotzil y Q Ìeqchi Ì, el cual integró un enfoque etnomédico, etnobotánico y transcultural, comparando estudios previos con el presente trabajo de campo. Para evaluar la eficacia de Ageratina para aliviar el dolor abdominal, se realizó un inventario de las moléculas reportadas en esta especie, así como de su actividad farmacológica, a través de una revisión bibliográfica. Los resultados mostraron que la epidemiología del dolor producido por TGI, su etnobotánica y el modelo explicativo del dolor abdominal fueron similares entre grupos étnicos. Asimismo, se identificaron 27 moléculas con efectos antiinflamatorios y antinociceptivos, lo que podría explicar por qué esta especie es culturalmente importante para los pobladores maya Tzeltal, Tzotzil y Q Ìeqch i Ì para el alivio del dolor abdominal, mientras que, desde el punto de vista biomédico, es una especie con potencial para inhibir el dolor visceral.
The current study is a comparison of the abdominal pain conception produced by gastrointestinal disorders, relieved by Ageratina ligustrina , among inhabitants of the Mayan Tzeltal, Tzotzil, and Q'eqchi' groups ethnomedical, ethnobotanical, and cross -cultural approaches were used to compare previous studies with the present field work. To evaluate the efficacy of A. ligustrina to relieve pain, also through a bibliographic review an inventory of the molecules present in this species was performed, as well as their pharmacological activity. The results showed that the epidemiology of pain produced by GID, its ethnobotany, and the explanatory model of abdominal pain are similar among ethnic groups. Likewise, 27 molecules with anti-inflammatory and anti-nociceptive effects were identified, which could explain why this species is culturally important for the Mayan Tzeltal, Tzotzil, and Q'eqchi' groups for the relief of abdominal pain, while, from a biomedical point of view, it is a species with potential to inhibit visceral pain.

BACKGROUND: Prior research has established the effectiveness of magnesium in relieving postoperative pain. This article aims to evaluate magnesium sulfate for perioperative analgesia in adults undergoing general abdominal surgery under general anesthesia. OBJECTIVE: The primary aim was to assess pain scores at 6 and 24 hours postoperatively in patients receiving magnesium sulfate vs. the control group. Secondary outcomes were postoperative opioid consumption, perioperative complications, and time to rescue analgesia. METHODS: A comprehensive database search identified studies comparing magnesium sulfate with control in adults undergoing general anesthesia for general abdominal surgery. Using random-effects models, data were presented as mean ± Standard Deviation (SD) or Odds Ratios (OR) with corresponding 95% Confidence Intervals (95% CI). A two-sided p-value < 0.05 was considered statistically significant. RESULTS: In total, 31 studies involving 1762 participants met the inclusion criteria. The magnesium group showed significantly lower postoperative pain scores at both early (within six hours) and late (up to 24 hours) time points compared to the control group. The early mean score was 3.1 ± 1.4 vs. 4.2 ± 2.3, and the late mean score was 2.3 ± 1.1 vs. 2.7 ± 1.5, resulting in an overall Mean Difference (MD) of -0.72; 95% CI -0.99, -0.44; p < 0.00001. The magnesium group was associated with lower rates of postoperative opioid consumption and shivering and had a longer time to first analgesia administration compared to the saline control group. CONCLUSION: Magnesium sulfate administration was linked to reduced postoperative pain and opioid consumption following general abdominal surgery.

This case report describes the management of a woman diagnosed with a retroperitoneal cystic tumor during pregnancy. The 29-year-old patient presented at 29 weeks of pregnancy with abdominal pain. A retroperitoneal tumor measuring 224 × 156 × 235 mm was identified on ultrasound and magnetic resonance imaging. The patient underwent cesarean section delivery of a healthy neonate at 37 weeks. Uncomplicated laparoscopic surgery was performed during the postpartum period, resulting in a histologic diagnosis of a retroperitoneal lymphangioma. A review of articles published between 2003 and 2023 on the diagnosis, management, and prognosis of gestational lymphangiomas was conducted using the PubMed, SCOPUS and SpringerLink databases. Ten articles, including case reports of lymphangiomas diagnosed during pregnancy, were identified. The most frequent location was the gastrointestinal tract, with no cases reported in the retroperitoneal area. A good perinatal outcome was reported in the majority of cases. Lymphangiomas are rare benign tumors that are even more uncommon during pregnancy. Watchful waiting can offer a good obstetric and perinatal prognosis.
RESUMO
INTRODUCTION: Abdominal aortic aneurysm (AAA) is a growing public health problem, and not all patients have access to surgery when needed. This study aimed to analyze spatiotemporal variations in AAA mortality and surgical procedures in Brazilian intermediate geographic regions and explore the impact of different surgical techniques on operative mortality. METHODS: A retrospective longitudinal study was conducted to evaluate AAA mortality from 2008 to 2020 using space-time cube (STC) analysis and the emerging hot spot analysis tool through the Getis-Ord Gi* method. RESULTS: There were 34,255 deaths due to AAA, 13,075 surgeries to repair AAA, and a surgical mortality of 14.92%. STC analysis revealed an increase in AAA mortality rates (trend statistic = +1.7693, p = 0.0769) and a significant reduction in AAA surgery rates (trend statistic = -3.8436, p = 0.0001). Analysis of emerging hotspots revealed high AAA mortality rates in the South, Southeast, and Central-West, with a reduction in procedures in São Paulo and Minas Gerais States (Southeast). In the Northeast, there were extensive areas of increasing mortality rates and decreasing procedure rates (cold spots). CONCLUSION: AAA mortality increased in several regions of the country while surgery rates decreased, demonstrating the need for implementing public health policies to increase the availability of surgical procedures, particularly in less developed regions with limited access to services.
