Hernia de Garengeot: presentación de un caso y revisión de la literatura / De Garengeot hernia: a case report and literature review

INTRODUCTION: Femoral hernias have a high risk of strangulation or obstruction, and their acute presentations are associated with a high risk of mortality, occurring in up to 60% of cases with complications. The presence of the appendix within the femoral sac has been described in a maximum of 1% of cases, which has been called Garengeot hernia, but only 0.08% with concomitant appendicitis. CASE REPORT: Woman 56 years old, cholecystectomized, with no other relevant history, 5 months of evolution, right femoral region volume increase, consultation for 24 hours of evolution of habitual pain exacerbation, CT scan showing complicated hernia, with appendix inside of the hernial sac. The right inguinal approach is performed, the cecal appendix is the only content within the hernial sac, with signs of acute appendicitis, appendectomy and hernia repair with Prolene mesh. Diagnosis is confirmed with biopsy. DISCUSSION AND CONCLUSION: Acute appendicitis within De Garengeot's hernia is extremely rare and often difficult to diagnose. The diagnosis of a femoral hernia appendicitis is often obscured by nonspecific clinical findings that indicate a complicated hernia. Computed tomography may be useful to definitively diagnose acute appendicitis contained within a femoral hernia. It is important to always consider De Garengeot hernia as a differential diagnosis in patients with inguinal mass of acute pain, so as not to delay its detection and management.

Un recorrido por la pared abdominal: evaluación de las hernias por tomografía computada multidetector / A tour of the abdominal wall: assessment of hernias by multidetector computed tomography

Si bien el diagnóstico de hernias de la pared abdominal es clínico y el estudio más indicado es la ecografía, en una gran cantidad de casos es difícil su evaluación o no se sospecha su presencia debido al biotipo del paciente, la ausencia de síntomas, la aparición de complicaciones o corresponde a algún tipo de hernia poco frecuente. Además, la debilidad de la pared abdominal generada por una cirugía predispone a la eventración de órganos, a veces poco habituales, como el hígado, la vejiga o el apéndice. La utilización de la tomografía computada multidetector (TCMD) brinda grandes ventajas cuando resulta dificultoso establecer el diagnóstico por otros métodos. También puede ser un hallazgo incidental a tener en cuenta por sus posibles complicaciones futuras. En el presente trabajo describimos los principales hallazgos por TCMD de las hernias y eventraciones de la pared abdominal (como la umbilical, epigástrica, hipogástrica, inguinal, de Spiegel, lumbar, obturatriz, intercostal e incisional) y su contenido.

Although the diagnosis of abdominal wall hernias is clinical, and the most appropriate study is ultrasound, in a lot of cases they are difficult to evaluate, or their presence is not suspected because of the biotype of the patient, the absence of symptoms, the presence of complications, or the appearance of rare hernias. Surgery weakness generated in the wall leads to organ hernia, sometimes unusual, as in the liver, bladder, or appendix. The use of multidetector computed tomography (MDCT) is a great advantage in these situations where the diagnosis can be difficult to determine with other methods. It also can be an incidental finding to consider eventual complications. In this paper, the main MDCT findings in abdominal wall hernias are described, including umbilical, epigastric, hypogastric, inguinal, Spiegel, lumbar, obturator, intercostal, and incisional, as well as their content.
