Resumen
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.
Abstract
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.
