RESUMO

Introducción. Los tumores desmoides son lesiones de los tejidos blandos, histológicamente benignas, poco frecuentes y con gran agresividad local y carencia de potencial metastásico. Se relacionan estrechamente con antecedentes traumáticos o quirúrgicos, como la cesárea, y su tratamiento generalmente es quirúrgico. Métodos. Presentamos una serie de tres pacientes intervenidas en nuestro centro durante el año 2020. Se revisan sus antecedentes y se describe su tratamiento. Resultados. En todas nuestras pacientes se encontró algún antecedente quirúrgico, dos cesáreas y una resección de un disgerminoma. El tratamiento empleado fue la resección quirúrgica con márgenes libres y reparación del defecto mediante malla. Conclusiones. El tumor desmoide es una patología poco frecuente, su diagnóstico se realiza mediante exámenes imagenológicos y se confirma con el estudio histológico; es importante hacer el diagnóstico diferencial con el sarcoma. La cirugía radical sigue siendo el tratamiento de elección, aunque algunos autores proponen el tratamiento conservador.


Introduction. Desmoid tumors are soft tissue lesions, histologically benign, rare and with great local aggressiveness and lack of metastatic potential. They are closely related to traumatic or surgical history such as caesarean section. Their treatment is generally surgical. Methods. We present a case series of three patients operated on in our center during the year 2020. Their history is reviewed and their type of treatment is presented. Results. In all our patients, surgical history was found (two caesarean sections and one resection of a dysgerminoma). The treatment used was surgical resection with free margins and mesh repair of the defect. Conclusions. Desmoid tumor is a rare pathology; its diagnosis is made by imaging studies, and confirmed by histology. It is important to make a differential diagnosis with sarcoma. Radical surgery remains the treatment of choice, although some authors propose conservative treatment.

RESUMO

Gastrointestinal Stromal Sarcomas (GIST) are mesenchymal neoplasms whose incidence accounts for 1-2% of digestive tumors, being located in the stomach (55-60%) and small intestine (30%). The advances in its knowledge and management succeeded in the last years have being spectacular. This review aims to summarize the most important of them for surgeons. We identified four areas of interest: molecular oncology, laparoscopic approach, management of GIST located at unusual locations, and management of advanced GIST. Advances in the field of molecular oncology lead to the discovery of new oncogenic mutations making the term Wil Type GIST obsolete. Moreover, these advances allow for the development of 2 new drugs: Avapritinib and Ripretinib, that added to the previous 3 commercially available drugs (imatinib, sunitinib and regorafenib) make possible the management of GIST with resistant mutations. The principles of the surgical management of primary GIST are well stablished which laparoscopic approach must accomplish. This approach is limited by 2 main factors: location and size. The diagnosis of GIST in unusual locations as esophagus, duodenum, rectum of out of the gastrointestinal tract (EGIST), implies an extraordinary therapeutic challenge, being imperative to manage them by surgeons and oncologist among others in the setting of a multidisciplinary team. The management of advanced/metastatic GIST has changed in a revolutionary fashion because surgery is now part of its treatment as adjuvant to tyrosine kinase inhibitors.


Los tumores del estroma gastrointestinal (GIST) suponen el 1-2% de los tumores digestivos, siendo su localización más frecuente el estómago (55-60%) y el intestino delgado (30%). Los avances más importantes sucedidos en los últimos años se centran en cuatro áreas: biología molecular, abordaje quirúrgico laparoscópico, manejo técnico del GIST en localizaciones inusuales y tratamiento e integración de la cirugía en el manejo del GIST avanzado. Los avances en el conocimiento de la biología molecular del GIST han dado lugar a la progresiva identificación de nueva mutaciones oncogénicas que hacen del concepto wild type obsoleto. Estos avances han permitido el desarrollo de dos nuevos fármacos, avapritinib y ripretinib, lo que permite el tratamiento de pacientes con mutaciones resistentes a las tres líneas terapéuticas clásicas. El tratamiento quirúrgico del GIST se rige por unos principios técnicos bien establecidos que el abordaje laparoscópico debe cumplir, abordaje que queda limitado por dos factores clave: localización y tamaño. El GIST de localización infrecuente (esófago, duodeno o recto, o extradigestivo) supone un reto terapéutico. Estos pacientes deben ser manejados en un contexto multidisciplinario. La cirugía queda integrada en el manejo del GIST avanzado, considerándose como adyuvante a los inhibidores de la tirosina cinasa.

RESUMO

Introducción: la rotura traumática del diafragma es una lesión infrecuente que aparece en politraumatismos o agresiones. Predomina en los varones entre 20 y 50 años de edad, siendo los accidentes de tráfico la principal causa en Europa. El diagnóstico preoperatorio requiere alto nivel de sospecha junto con las adecuadas exploraciones radiológicas. El retraso diagnóstico se asocia con elevada morbilidad y mortalidad, constituyendo la intervención quirúrgica inmediata un factor determinante para el éxito en el tratamiento de estos pacientes. El objetivo de este informe fue analizar la incidencia y epidemiología de la rotura traumática del diafragma en nuestro medio, y exponer nuestros resultados en el diagnóstico y tratamiento de esta lesión. Material y métodos: presentamos siete casos correspondientes al periodo 1999-2005 y analizamos el motivo de ingreso, la clínica, las formas de diagnóstico, las lesiones asociadas, el tratamiento y la evolución. Conclusiones: el diagnóstico de rotura diafragmática es difícil debido a su baja frecuencia y a su sintomatología variable, no obstante, debe ser considerado en todo paciente politraumatizado. La tomografía helicoidal es la exploración radiológica de elección y la vía de abordaje más adecuada es la laparotomía media.


BACKGROUND: Traumatic diaphragmatic rupture is an infrequent lesion usually found in polytrauma cases or after violent attacks. Patients are usually males between 20 and 50 years old, and car accidents are the main causes in Europe. Preoperative diagnosis must be based on a high level of suspicion and appropriate radiological explorations. Diagnostic delay is associated with high morbidity and mortality and early surgical treatment is required for successful management. We undertook this study to analyze the epidemiology of diaphragmatic rupture and to report our results in the diagnosis and treatment of this injury. METHODS: We present seven cases from 1999 through 2005. We analyzed the reasons for admission, signs and symptoms, diagnostic approach, associated lesions, treatment and course. CONCLUSION: Diagnosis of diaphragmatic rupture is difficult due to changeable symptomatology; nevertheless, it must be considered in all polytraumatized patients. Computerized tomography is the radiological exploration of choice and the most suitable surgical approach is laparotomy.
