RESUMO

Background: Acute appendicitis is widely recognized as the prevailing abdominal surgical emergency globally, exhibiting an annual incidence ranging from 96.5 to 100 cases per 100,000 adults. Conversely, situs inversus totalis is a rare anatomical anomaly characterized by the complete reversal of the chest and abdominal organs, occurring in approximately 1 out of every 10,000 to 50,000 individuals. Clinical case: 53-year-old female patient who presented to the emergency department with a complaint of diffuse abdominal pain of colic nature that had persisted for 5 days. The patient referred systemic hypertension, pre-diabetes mellitus type 2, and situs inversus as relevant medical history. A laparotomy procedure was conducted, revealing a perforated appendix located in the right hypochondrium. Additionally, the patient exhibited situs inversus totalis, with the colon positioned in its normal anatomical location. Conclusions: Due to the low incidence of situs inversus totalis, in cases similar to the one presented, the utilization of image studies and laboratory studies is imperative for accurate diagnosis. In the face of diagnostic suspicions and inconclusive paraclinical studies, the most effective approach is to pursue surgical examination and intervention, preferably utilizing laparoscopic techniques.

Introducción: la apendicitis aguda es la urgencia quirúrgica abdominal más frecuente en el mundo, con una incidencia anual de 96.5 a 100 casos por 100,000 adultos. Por otra parte, el situs inversus totalis es un trastorno posicional inverso de los órganos torácicos y abdominales con una incidencia de 1 en 10,000 a 50,000 personas. Caso clínico: paciente del sexo femenino de 53 años que se presentó en sala de urgencias refiriendo dolor abdominal difuso tipo cólico de 5 días de evolución. La paciente refirió hipertensión arterial sistémica esencial, prediabetes mellitus tipo 2 y situs inversus. Se realizó intervención quirúrgica (laparotomía) en la que se encontró el apéndice perforado en hipocondrio derecho y situs inversus totalis con colon en posición anatómica normal. Conclusiones: debido a la baja incidencia del situs inversus totalis, el diagnóstico en casos como el presentado representa un reto en el que el uso de estudios de imagen y laboratorio resulta indispensable. Ante la sospecha diagnóstica y estudios paraclínicos con resultados no concluyentes, la mejor estrategia consiste en la exploración y el manejo quirúrgicos, preferentemente laparoscópicos.

RESUMO

Introducción. La transposición de los órganos debido al situs inversus (SI) es una rara afección que dificulta el diagnóstico de la apendicitis aguda. Esta condición hace que la sintomatología del paciente y los hallazgos al examen físico puedan ser atípicos, lo que demanda el uso de imágenes para la confirmación diagnóstica en la mayoría de los casos. Métodos. Se describieron tres casos de apendicitis en pacientes con diagnóstico de situs inversus. Dos de ellos tenían el antecedente conocido, mientras el tercer caso fue diagnosticado de forma intraoperatoria. Resultados. En dos pacientes se decidió llevar a cirugía vía laparoscópica sin imágenes diagnósticas adicionales. Los pacientes evolucionaron de manera satisfactoria. Conclusión. Siempre se debe considerar la apendicitis dentro de los diagnósticos diferenciales en los pacientes con dolor en fosa ilíaca izquierda. Es fundamental diagnosticar y tratar la apendicitis de manera efectiva para minimizar las complicaciones asociadas. La importancia de la anamnesis y la sospecha clínica del examinador son vitales en estos casos, que se pueden confirmar con las imágenes diagnósticas. Pueden existir casos en donde la condición clínica del paciente no permita la realización de estudios diagnósticos por imágenes; esto apoya cada vez más el uso del abordaje laparoscópico. Se recomienda considerar el abordaje laparoscópico en primera instancia, ya que nos permite la confirmación diagnóstica de situs inversus totalis en caso de que el antecedente sea desconocido y facilita el manejo oportuno de la urgencia.

Introduction. Organ transposition due to situs inversus (SI) is a rare condition that makes the diagnosis of acute appendicitis difficult. This condition entails that the patient' symptoms and physical examination findings may be atypical, which requires the use of images for diagnostic confirmation in most cases. Clinical cases. Three cases of appendicitis in patients diagnosed with situs inversus are described. Two of them had a known medical history, while the third case was diagnosed intraoperatively. Results. In two patients it was decided to undergo laparoscopic surgery without additional diagnostic images. The patients progressed satisfactorily. Conclusion. Appendicitis should always be considered in the differential diagnoses in patients with pain in the left iliac fossa. It is essential to diagnose and treat appendicitis effectively to minimize associated complications. The importance of the anamnesis and the examiner's clinical suspicion are vital in these cases, which can be confirmed with diagnostic images. There may be cases where the patient's clinical condition does not allow diagnostic imaging studies to be performed, increasingly supports the use of the laparoscopic approach. It is recommended to consider the laparoscopic approach in the first instance, since it allows us to confirm the diagnosis of situs inversus totalisin case the history is unknown and facilitates timely management of the emergency.

RESUMO

ABSTRACT BACKGROUND: Bile duct injury (BDI) causes significant sequelae for the patient in terms of morbidity, mortality, and long-term quality of life, and should be managed in centers with expertise. Anatomical variants may contribute to a higher risk of BDI during cholecystectomy. AIMS: To report a case of bile duct injury in a patient with situs inversus totalis. METHODS: A 42-year-old female patient with a previous history of situs inversus totalis and a BDI was initially operated on simultaneously to the lesion ten years ago by a non-specialized surgeon. She was referred to a specialized center due to recurrent episodes of cholangitis and a cholestatic laboratory pattern. Cholangioresonance revealed a severe anastomotic stricture. Due to her young age and recurrent cholangitis, she was submitted to a redo hepaticojejunostomy with the Hepp-Couinaud technique. To the best of our knowledge, this is the first report of BDI repair in a patient with situs inversus totalis. RESULTS: The previous hepaticojejunostomy was undone and remade with the Hepp-Couinaud technique high in the hilar plate with a wide opening in the hepatic confluence of the bile ducts towards the left hepatic duct. The previous Roux limb was maintained. Postoperative recovery was uneventful, the drain was removed on the seventh post-operative day, and the patient is now asymptomatic, with normal bilirubin and canalicular enzymes, and no further episodes of cholestasis or cholangitis. CONCLUSIONS: Anatomical variants may increase the difficulty of both cholecystectomy and BDI repair. BDI repair should be performed in a specialized center by formal hepato-pancreato-biliary surgeons to assure a safe perioperative management and a good long-term outcome.

RESUMO RACIONAL: As lesões de via biliar (LVB) impõem sequelas significativas ao paciente em termos de morbidade, mortalidade e qualidade de vida a longo prazo, devendo ser manejadas em centros especializados. Variantes anatômicas podem contribuir para um maior risco de LVB durante colecistectomia. OBJETIVOS: Relatar paciente com lesão de via biliar associado a situs inversus totalis. MÉTODOS: Paciente do sexo feminino, 42 anos, com histórico prévio de situs inversus totalis e LVB inicialmente reparada simultaneamente à lesão, há 10 anos, por um cirurgião não especializado. Ela foi encaminhada a um centro especializado devido a episódios recorrentes de colangite e um padrão laboratorial colestático. Colangiressonância revelou uma grave estenose anastomótica. Devido à sua idade jovem e colangites recorrentes, foi submetida a uma revisão cirúrgica da hepaticojejunostomia com técnica de Hepp-Couinaud. Até onde sabemos, este é o primeiro relato de reparo de LVB em um paciente com situs inversus totalis. RESULTADOS: A hepaticojejunostomia realizado prèviamente foi desfeita e refeita empregando a técnica de Hepp-Couinaud, alta na placa hilar, com uma ampla abertura na confluência dos ductos biliares em direção ao ducto hepático esquerdo. A alça de roux anterior foi mantida. A recuperação pós-operatória transcorreu sem intercorrências, o dreno foi removido no sétimo dia pós-operatório, e a paciente está agora assintomática, com bilirrubina e enzimas canalículares normais, e sem mais episódios de colestase ou colangite. CONCLUSÕES: Variantes anatômicas podem aumentar a dificuldade tanto da colecistectomia quanto do reparo de LVB, o qual deve ser realizado em um centro especializado por cirurgiões hepatobiliares para garantir um manejo perioperatório seguro e um bom resultado a longo prazo.

RESUMO

Se presenta el caso de un paciente varón de 77 años con diagnóstico de colecistitis crónica calculosa y coledocolitiasis, con antecedente de situs inversus totalis. Se le realizó una colecistectomía con exploración de vías biliares laparoscópica, utilizando la "técnica francesa en espejo", con extracción de los cálculos. El paciente evolucionó favorablemente. El objetivo del presente trabajo es dar a conocer el caso clínico que es poco frecuente su reporte en la literatura mundial (solo 9 casos). Su importancia radica en que sería el primer reporte de caso clínico publicado de una colecistectomía y exploración de vías biliares laparoscópica con retiro del cálculo en colédoco en un paciente con situs inversus totalis, realizado en el Perú.

We present the case of a 77-year-old male patient with a diagnosis of chronic calculous cholecystitis and choledocholithiasis, with a history of situs inversus totalis. Therefore, a laparoscopic cholecystectomy with common bile duct exploration were performed, using the "french mirror technique", with stone extraction. Patient evolved favorably. The aim of this study is to present this clinical case that is rarely reported in the world literature (only 9 cases). Its importance lies in the fact that it would be the first published clinical case report of a laparoscopic cholecystectomy and bile duct exploration with removal of the common bile duct stones in a patient with situs inversus totalis, performed in Peru.

RESUMO

Situs inversus totalis (SIT) is a congenital condition in which the major visceral organs are reversed or in a mirror image from their normal positions that affects one per 10,000 live births. It is associated with dextrocardia (DXC) in which the heart is located on the right side of the chest. We present a challenging cardiac resynchronization therapy (CRT) implantation in a 60-year-old man with SIT-DXC, heart failure, extreme bradycardia, wide QRS, and left ventricular (LV) dysfunction. The procedure was complex due to the mirror-image anatomy and the tortuous origin of the coronary sinus (CS) branches that required a subselection catheter for adequate lead implantation.

RESUMO

Introducción: El situs inversus totalis es una condición congénita en la cual los órganos torácicos y abdominales se encuentran en posición contraria a la posición habitual. En la literatura quirúrgica internacional se encuentran publicados no más de 55 casos de colecistectomía en pacientes con situs inversus totalis. La resolución laparoscópica de una paciente en nuestra Institución nos permite revisar esta particular condición patológica. Caso Clínico: Paciente femenino de 43 años de edad hospitalizada por una colecistitis aguda la cual es resuelta por vía laparoscópica sin incidentes. Material y Método: Se resume la literatura actual mediante una extensa revisión en PubMed de los reportes más relevantes. Considerando que todos los artículos publicados son casos clínicos o pequeñas series de casos, se presentan los resultados de esta revisión en tablas con estadística descriptiva básica. Discusión: Se discuten las características generales de estos pacientes, la presentación clínica, diagnóstico y técnica quirúrgica. Conclusión: La colecistectomía laparoscópica constituye el estándar de oro en pacientes con situs inversus y patología biliar, la cual debe ser realizada por un cirujano experimentado acomodando los trocares apropiadamente, debido a las dificultades técnicas que se encuentran en estos pacientes por las anomalías anatómicas propias de esta condición. El diagnóstico radiológico actual permite la planificación del abordaje y del procedimiento quirúrgico apropiado para cada paciente.

Introduction: Situs inversus totalis is a congenital condition in which the thoracic and abdominal organs are in the opposite position from normal anatomy. We found no more than 55 cases of cholecystectomy in patients with situs inversus totalis published in the international surgical literature. The laparoscopic resolution of a patient in our Institution allows us to review this particular pathological condition. Clinical Case: A 43-year-old female patient was admitted for acute cholecystitis and was resolved laparoscopically without any incidents. Material and Method: We summarized the current literature through an extensive PubMed review of the most relevant reports. Considering that all published articles are clinical cases or small case series, we present the results of this review in a table with basic descriptive statistics. Discussion: We discuss the general characteristics of these patients, clinical presentation, diagnosis, and surgical technique. Conclusions: Laparoscopic cholecystectomy is the gold standard in patients with situs inversus and biliary pathology, which must be performed by an experienced surgeon, properly accommodating the trocars due to the technical difficulties in these patients secondary to anatomical anomalies typical of this condition. Current radiological diagnosis allows planning the appropriate approach and surgical procedure for each patient.

Reporte: Se diagnosticó apendicitis aguda en un paciente varón de 28 años que conocía su anormalidad anatómica y se corroboró con imágenes tomográficas y la exploración laparoscópica. Ingresó a emergencia con 30 horas de dolor abdominal con inicio en epigastrio y posterior irradiación hacia la fosa iliaca izquierda. La tomografía confirmó su condición de situs inversus totalis y signos patológicos en la apendicitis localizada en FII; se realizó la intervención por laparoscopia sin complicaciones. Discusión: En pacientes con dolor en el cuadrante inferior izquierdo es importante un adecuado diagnóstico diferencial y el conocimiento previo de una anormalidad anatómica comunicada oportunamente hace viable un diagnóstico adecuado y una resolución quirúrgica exitosa.

Introduction: Situs inversus totalis is a rare congenital malformation, characterized by an inverted position of the thoracic and abdominal organs, negatively influencing the diagnostic approach and surgical treatment. Report: Acute appendicitis was diagnosed in a 28-year-old male patient who knew his anatomical abnormality and was corroborated with tomographic images and laparoscopic exploration. He was admitted to the emergency room with 30 hours of abdominal pain with onset in the epigastrium and subsequent radiation to the left iliac fossa. The tomography confirmed his condition of situs inversus totalis and pathological signs in localized appendicitis in FII; The laparoscopic intervention was performed without complications. Discusions: In patients with pain in the left lower quadrant, an adequate differential diagnosis is important and prior knowledge of an anatomical abnormality communicated in a timely manner, that makes feasible an adequate diagnosis and successful surgical resolution.

RESUMO

Resumen Introducción: El situs inversus totalis asociado a la transposición de grandes arterias es una condición médica rara y poco descrita. Existen pocos casos reportados con esta asociación, los cuales, en su mayoría, corresponden a pacientes adultos que presentan una transposición de grandes arterias corregida congénitamente. La complejidad del caso descrito está demarcada tanto por su etiología, como por su baja frecuencia de aparición y reto quirúrgico. Caso clínico: se describe el caso de un neonato con diagnóstico antenatal de transposición de grandes arterias, asociado a hallazgo de dextrocardia y dextrogastria que sugirió situs inversus totalis en radiografía de tórax posnatal, en quien se realizó procedimiento de Jatene de mayor complejidad a la usual por su anatomía. Conclusiones: La presencia de una asociación entre el situs inversus totalis y otra malformación anatómica, como la transposición de grandes arterias, es poco frecuente. Sin embargo, dicha asociación es un factor determinante tanto para la realización oportuna del diagnóstico, como para la elección del tratamiento apropiado y la presentación de posibles complicaciones posteriores.

Abstract Introduction: Situs inversus totalis associated with transposition of the great arteries is a rare and infrequently described medical condition. There are few reported cases of this association, most of which are in adult patients with congenitally corrected transposition of the great arteries. Objective: The complexity of the described case is marked by both its etiology as well as its infrequent presentation and surgical challenge. Clinical case: This was a newborn with a prenatal diagnosis of transposition of the great arteries associated with a finding of dextrocardia and dextrogastria which suggested situs inversus totalis on the postnatal chest x-ray, who underwent a more complex Jatene procedure than usual because of his anatomy. Conclusions: Situs inversus totalis associated with another anatomical malformation, such as transposition of the great arteries, is uncommon. However, this association is a determining factor for both timely diagnosis as well as for choosing the appropriate treatment, and for the development of possible subsequent complications.

RESUMO

RESUMEN Se presenta el caso de un paciente masculino de 22 años con trombosis venosa profunda de vena cava inferior, iliacas y femorales y que presenta como factores de riesgo una agenesia de la porción suprarrenal de la vena cava inferior y lupus eritematoso sistémico. Además, se evidenció la presencia de situs inversus total, condición que se asocia a malformaciones venosas presentes en el caso. Como tratamiento se utilizó anticoagulación con heparina de bajo peso molecular y posteriormente anticoagulante oral. A pesar el extenso territorio de la trombosis se descartó la necesidad de instalar filtro en la vena cava inferior por la ausencia de la misma en la aurícula derecha. Se intentó sin éxito la repermeabilización con trombolítico.

ABSTRACT We present the case of a 22-year-old male patient with deep vein thrombosis of the inferior vena cava, iliac and femoral veins, who presents as risk factors an agenesis of the suprarenal portion of the inferior vena cava and systemic lupus erythematosus. In addition, the presence of total situs inversus was evidenced, a condition that is associated with venous malformations present in the case. As treatment, anticoagulation was used with low molecular weight heparin and subsequently oral anticoagulant. Despite the extensive territory of the thrombosis, the need to install a filter in the inferior vena cava was ruled out due to its absence in the right atrium. Repermeabilization with thrombolytic therapy was attempted without success.

RESUMO

INTRODUCTION AND IMPORTANCE: Obesity is a worldwide pandemic and is closely associated with an increased risk of comorbidities and overall mortality. Surgery has emerged as an essential strategy to ameliorate obesity-attributable comorbidities and as a powerful weight-loss tool. Due to the increasing number of obese patients predicted to elect surgery, individuals with rare anomalies such as situs inversus can be expected. CASE PRESENTATION: We present the case of a 49-year-old woman with situs inversus with levocardia. She had a high BMI and was admitted for bariatric surgery. After several adjustments to our technique, the procedure was completed without complications. CLINICAL DISCUSSION: Laparoscopic bariatric surgeries are highly demanding; variations from the normal anatomy could challenge the medical team. CONCLUSION: Preoperative diagnosis and highly trained surgeons is of paramount importance to adequately treat every patient.

RESUMO

INTRODUCTION: Situs inversus totalis (SIT) is an autosomal recessive congenital disorder. Acute cholecystitis is a diagnosis challenge in patients with SIT. CLINICAL CASE: A 26-year-old female who presented with atypical gallbladder colic. Assessed by Surgery, concluding diagnosis of acute cholecystitis and SIT. Laparoscopic cholecystectomy was performed. DISCUSSION: SIT is a rare congenital pathology, defined by the transposition of thoracic and abdominal viscera. Most patients are asymptomatic and they're discovered incidentally. The SIT goes far beyond the paradigm of treatments and surgical techniques. CONCLUSIONS: The pathology turns into a behavior modification for surgical treatment, however, it is possible to carry them out successful procedure.

INTRODUCCIÓN: El situs inversus total (SIT) es un trastorno congénito autosómico recesivo. La colecistitis aguda es un reto diagnóstico en los pacientes con SIT. CASO CLÍNICO: Mujer de 26 años con cólico vesicular atípico. Valorada por cirugía, se concluye el diagnóstico de colecistitis aguda y SIT. Se realiza colecistectomía laparoscópica, sin complicaciones. DISCUSIÓN: En el SIT definido por transposición de vísceras torácicas y abdominales, la mayoría de los pacientes son asintomáticos y se descubre incidentalmente. El SIT supera el paradigma de tratamientos y técnicas quirúrgicas. CONCLUSIONES: Esta patología requiere modificación de conductas para el tratamiento quirúrgico, pero es posible realizarlo con éxito.

RESUMO

ABSTRACT Introduction: About half a million patients in Colombia are currently infected with Trypanosoma cruzi. However, little is known about patients with Chagas disease and anatomical defects such as dextrocardia. Case presentation: A 52-year-old male patient with a 4-year history of dyspnea, chest pain, lower limb edema and syncope (requiring hospitalization), arrhythmias and dextrocardia, underwent serological tests for T. cruzi that were positive. A literature review was conducted to find case reports of patients with dextrocardia or situs inversus and Chagas disease in order to determine the proper treatment. Conclusion: Cases of patients with dextrocardia and Chagas disease are rare. Besides the reported case, only three other cases were found in the literature, which were relatively similar, although they could be considered more severe. According to the findings, the use of etiological treatment is acceptable in patients with coronary anatomic abnormalities and T. cruzi infection. The present case draws attention to the importance of adequately approaching and monitoring this type of patient.

RESUMEN Introducción. En la actualidad, en Colombia hay aproximadamente medio millón de personas infectadas con Trypanosoma cruzi; sin embargo, no hay mucha información sobre pacientes que viven con enfermedad de Chagas y anomalías anatómicas como la dextrocardia. Presentación del caso. Paciente masculino de 52 años con cuadro clínico de aproximadamente cuatro años de evolución consistente en disnea, dolor torácico, edema de extremidades inferiores, síncope (que requirió hospitalización), arritmias y dextrocardia, a quien se le practicaron pruebas serológicas para T. cruzi que resultaron positivas. Con el fin de establecer el tratamiento adecuado, se realizó una revisión de la literatura buscando reportes de casos de pacientes con dextrocardia o situs inversus y enfermedad de Chagas. Conclusión. Los casos de pacientes con dextrocardia y enfermedad de Chagas son poco frecuentes: además del caso reportado, en la literatura solo se encontraron tres reportes adicionales, los cuales fueron relativamente similares, aunque podrían considerarse más severos. Según los hallazgos, el uso de tratamiento etiológico es adecuado en pacientes con anormalidades anatómicas cardiovasculares e infección por T. cruzi. El presente caso llama la atención sobre la importancia de tener un enfoque y seguimiento adecuados en este tipo de pacientes.

RESUMO

El situs inversus es una rara anomalía congénita. El primer caso de colecistectomía laparoscópica en un paciente con situs inversus totalis se realizó en 1991. Se presenta el caso de un paciente varón, de 66 años, que presentó litiasis vesicular. Durante el protocolo preoperatorio se documentó situs inversus totalis. Fue intervenido quirúrgicamente de forma electiva y se realizó colecistectomía laparoscópica sin complicaciones. Diversos autores reportan casos en los que realizaron colecistectomía laparoscópica con tres y cuatro trócares, y con diferente posición de los puertos. Es técnicamente demandante realizar una colecistectomía laparoscópica en pacientes con situs inversus totalis, pero es seguro realizarla.Situs inversus totalis is a rare congenital anomaly. The first case of laparoscopic cholecystectomy in a patient with situs inversus totalis was reported in 1991. A 66-year-old male with cholelithiasis. Clinical assessment and radiological investigation diagnosed situs inversus totalis. Laparoscopic cholecystectomy was performed electively without complications. Authors report changes in the number and position of trocars to perform laparoscopic cholecystectomy. Although it is technically challenging, it is safe to perform a laparoscopic cholecystectomy in a patient with situs inversus totalis.

RESUMO

INTRODUCTION: Dextrocardia is characterized by the positioning of the heart to the right of the thoracic cavity, usually with the apex oriented to the right and its inverse anatomy 1,2. It is a rare congenital pathology that can be associated with other congenital cardiac anomalies, as well as a change in position of all thoracoabdominal structures 1-4. Its diagnosis in adult life is usually incidental. We present the clinical case of a 64-year-old man with an electrocardiogram that showed deviation of the QRS complex axis to the extreme right and a physical examination compatible with dextrocardia, which was later confirmed with images. OBJECTIVES: To review the medical literature related to the diagnosis of dextrocardia through the presentation of a clinical case. METHODS: The clinical data of the case were collected by means of anamnesis, physical examination and specialized exams of the patient, as well as his clinical file. The literary review was made using the MEDLINE® search engine for scientific journals. RESULTS: Dextrocardia affects less than 1% of the general population according to the studies reviewed. Its importance lies in the association with other congenital pathologies such as cardiac and extracardiac structural malformations, which increases morbidity and mortality in this group of patients. It is imperative, when suspected, complete the study with images that allow confirming or ruling out other structural anomalies.

RESUMO

Resumen: El situs inversus totalis es la inversión congénita completa de órganos torácicos y abdominales. Se presenta el caso de una paciente de 3 años sin antecedentes médicos previos, a quien en atención primaria, y por un cuadro respiratorio agudo, se evidencia el hallazgo de dextrocardia y burbuja gástrica a derecha en la radiografía de tórax, sospechándose situs inversus totalis. Fue derivada a cardiología infantil donde se confirmó el diagnóstico con un ecocardiograma transtorácico, asociado a un hallazgo de preexcitación ventricular en el electrocardiograma. Una vez resuelto el cuadro respiratorio agudo, la paciente se mantiene controlada de manera periódica en atención primaria y por especialista de manera semestral.

Abstract: Situs inversus totalis is the complete congenital inversion of thoracic and abdominal organs. We present the case of a 3-year-old girl with no previous medical history. When seen with an acute respiratory syndrome, dextrocardia and gastric bubble on the right side led to the diagnosis of Situs inversus. She was referred to infant cardiology where the diagnosis was confirmed with a transthoracic echocardiogram. In addition, the electrocardiogram identified the presence of ventricular preexitation. Once the acute respiratory symptoms subsided, the patient remains controlled periodically in primary care and by a specialist every six months. No episodes of tachycardia have been detected.

RESUMO

ANTECEDENTES: El situs inversus totalis (SIT) es una condición congénita infrecuente, en la cual los órganos asimétricos del abdomen y el tórax presentan una disposición en espejo; su asociación con aneurismas de aorta abdominal (AAA) es inusual y supone un reto quirúrgico. CASO CLÍNICO: Presentamos el caso de una paciente con SIT y AAA, por lo que se decide llevar a reparación quirúrgica. El AAA en pacientes con SIT es infrecuente; en la literatura hay pocos casos reportados. A pesar de ser una relación inusual, su tratamiento de forma electiva fue segura en nuestra paciente. BACKGROUND: The situs inversus totalis (SIT) is a rare congenital condition, in which the asymmetric organs of the abdomen and thorax have a mirror ubication; its association with abdominal aortic aneurysms, is unusual. CASE REPORT: We will present the case of a patient with SIT, who has an abdominal aortic aneurysm, taken to open surgical repair. The presentation of abdominal aortic aneurysms in patients with infrequent SIT, with few reported cases in the literature. Despite being an unusual relationship, elective treatment was safe, as we seen in our patient.

RESUMO

INTRODUCTION: Situs Inversus Totalis (SIT) is a rare finding of complete reversal of the thoracic and abdominal organs with an estimated incidence of 0.005%-0.01% in the population. Severe trauma has not been reported in this population. We present a case of multiple chest stab wounds in a patient with previously unknown SIT. PRESENTATION OF CASE: A 39-year-old male was admitted to the emergency room with multiple stab wounds on the left side of the chest. Upon admission the patient was hypotensive, with miosis and intubated. Significant ECG findings were an inverted P wave, inverted QRS complex and inverted T wave in V1. A chest CT scan showed SIT, hemopneumothorax on the left side and, despite multiple stab wounds on the left side of the chest, no cardiac damage. The surgical team decided for a conservative approach and the patient remained in the ICU for two days. After five days he was discharged in good clinical conditions. DISCUSSION: SIT generally does not have a clinical relevance throughout the patients life and most diagnoses are coincidental. However, when discovered in acute surgical cases, it requires an accurate evaluation by the surgical team due to anatomical differences that may produce undesirable outcomes in emergency cases such as appendicitis and general trauma. CONCLUSION: There have been very few reports of SIT and trauma in the medical literature. This might be the first ever reported case of a patient with SIT who suffered multiple stab wounds on the left side of the chest and was saved because of his condition.

RESUMO

BACKGROUND: Situs inversus totalis is a rare genetic condition characterized by the transposition of organs to the opposite side of the body, consequently, clinical syndromes show an atypical clinical picture creating a challenge for the surgery team and predisposing to delays in treatment and diagnosis. Laparoscopic cholecystectomy is the gold standard for acute cholecystitis, and in patients with situs inversus, the laparoscopic technique must be modified to accommodate the patient's anatomy. CASE PRESENTATION: We present the case of a 55-year-old male patient without any past medical history, he presented to the emergency room with abdominal pain in his upper left quadrant. After a thorough examination, acute cholecystitis and situs inversus was diagnosed. He underwent a modified laparoscopic cholecystectomy without complications. In his postoperative period, residual choledocholithiasis was identified and ERCP was done. On follow-ups, the patient is doing well. CONCLUSIONS: Although rare and technically demanding, laparoscopic cholecystectomy and ERCP in a patient with situs inversus is feasible. The altered anatomy could lead to complex procedures, therefore proper planning and careful execution of intraoperative techniques are required to treat these patients safely and effectively.
