Relationship between the anatomical location and the selective non-operative management of penetrating stab wounds in the abdomen.

INTRODUCTION: The relationship between the anatomical location of penetrating abdominal stab wounds (SW) and the rate of selective non-operative management (SNOM) based on that location is scarcely reflected in the specialized literature. Our main objective has been to assess this rate based on the anatomical location, and our results. METHODS: Retrospective review of a prospective registry of abdominal trauma from April 1993 to June 2020. The two study groups considered were the Operative Management (OM), and the SNOM, including in this one the use of diagnostic laparoscopy. Penetrating SWs in the abdomen were classified according to anatomical location. RESULTS: We identified 259 patients who fulfilled the inclusion criteria. SNOM was applied in 31% of the patients with a success rate of 96%, and it was more frequent in the lumbar, flank, and thoraco-abdominal regions; within the anterior abdomen it was more applicable in the RH, followed by the LH and epigastrium, respectively. An unnecessary laparotomy was done in 21% of patients, with the highest number in the epigastrium. Taking into account the unnecessary laparotomies and the rates of successful SNOM, 70.5% of lumbar, 66.5% of epigastric, 62% of flank, and 59% of RH penetrating SW could have been managed without a laparotomy. CONCLUSIONS: SNOM of penetrating SW in the abdomen has been safer and more applicable in those located in the lumbar, flank, epigastric, and RH regions.

Relación entre la localización anatómica y el manejo selectivo no operatorio de las heridas por arma blanca penetrantes en abdomen / Relationship between the anatomical location and the selective non-operative management of penetrating stab wounds in the abdomen

Introducción: La localización anatómica de las heridas por arma blanca (HAB) penetrantes en abdomen y su relación con el manejo selectivo no operatorio (MSNO) tiene escaso reflejo en la literatura especializada. Nuestro objetivo principal ha sido valorar la tasa de MSNO en función de esa localización anatómica, y sus resultados. Métodos: Revisión retrospectiva del registro prospectivo de trauma abdominal desde abril de 1993 hasta junio de 2020. Los dos grupos a estudio fueron manejo operatorio (MO) y MSNO, incluyendo en este último grupo el uso de laparoscopias exploradoras como método diagnóstico. Se clasificaron las HAB penetrantes en abdomen en función de su localización anatómica. Resultados: Identificamos 259 pacientes que cumplían los criterios de inclusión. El MSNO se aplicó en el 31% de los pacientes, con una tasa de éxito del 96,5%. En las HAB de las regiones lumbares, flancos y toracoabdominales fue donde se optó más frecuentemente por este manejo; y en el abdomen anterior fue más aplicable en el hipocondrio derecho (HD), seguido del hipocondrio izquierdo (HI) y epigastrio. Se realizó una laparotomía innecesaria en el 21%, con la cifra más alta en el epigastrio. Teniendo en cuenta los porcentajes de MSNO y laparotomías evitables en cada región, el 70,5% de las HAB lumbares, el 66,5% de las epigástricas, el 62% de flancos y el 59% de HD se podrían haber manejado con éxito sin laparotomía. Conclusiones: El MSNO de las HAB penetrantes en abdomen ha resultado más seguro y aplicable en las localizadas en las regiones lumbares, flancos, epigastrio e HD (AU)

Liposarcoma del cordón espermático simulando una hernia inguinal incarcerada / Liposarcoma of the spermatic cord mimicking an incarcerated inguinal hernia

INTRODUCCIÓN: Los tumores paratesticulares representan del 7%-10% de las masas intraescrotales. Los sarcomas abarcan el 90% de las lesiones malignas del cordón espermático y de éstas, aproximadamente, el 3%-7% son liposarcomas. CASO CLÍNICO: Presentamos el caso de un varón de 45 años, que consultó en urgencias por una masa inguinoescrotal derecha no reductible, diagnosticándose de hernia inguinal incarcerada. Se realizó cirugía urgente evidenciando una gran tumoración de aspecto lipomatoso, dependiente de cordón espermático. Se realizó orquiectomía y hernioplastía inguinal. La anatomía patológica, reveló un liposarcoma bien diferenciado de cordón espermático. Posteriormente, se realizó estudio de extensión, sin afectación a distancia y no precisó tratamiento adyuvante. Actualmente, tras dos años de seguimiento no ha presentado recidiva. DISCUSIÓN: Sólo alrededor de 200 casos han sido comunicados previamente en la literatura y sólo 61 de éstos se presentaron simulando una hernia inguinal incarcerada. Debido a la baja incidencia de esta patología es difícil de conocer la historia natural y llegar a conclusiones sobre los resultados del tratamiento, el cual hasta el momento sigue siendo la orquiectomía radical, con escisión amplia de los tejidos locales. El papel de la radio y quimioterapia aun es controvertido. CONCLUSIONES: Los sarcomas del cordón espermático son neoplasias raras con alta tasa de recurrencia local. Su manejo inicial es quirúrgico. Se requiere de un alto índice de sospecha clínica para el diagnóstico ya que las implicaciones oncológicas varían en función del tratamiento que, en ocasiones, es llevado a cabo por cirujanos generales al simular una hernia inguinal.

INTRODUCTION: Paratesticular tumors represent 7%-10% of intraescrotal masses. Sarcomas account for 90% of malignant lesions of the spermatic cord and of these approximately 3%-7% are liposarcomas. CLINICAL CASE: This is the case of a 45 year old male who consulted in the emergency department for a non-reducible right inguino-scrotal mass and was diagnosed with an incarcerated inguinal hernia. Emergency surgery was performed which revealed a large lipomatous tumor, originating from the spermatic cord. Orchiectomy and hernioplasty were performed. Histopathology revealed a well-differentiated liposarcoma of the spermatic cord. Later extension study was conducted, without distant affectation, and did not require adjuvant treatment. Today, after two years of monitoring has been no recurrence. DISCUSSION: Only about 200 cases have been previously reported in the literature and only 61 of these were presented mimicking an incarcerated inguinal hernia. Due to the low incidence of this disease it is difficult to know the natural history and draw conclusions on the results of treatment, which so far remains the radical orchiectomy with wide local excision of the tissue. The role of radiotherapy and chemotherapy is still controversial
