Abstract

We analyze the case of a patient with intermittent episodes of lower gastrointestinal bleeding and suspected Meckel's diverticulum, whose presence was confirmed by 99mTc-pertechnetate scintigraphy. A previous exploratory laparotomy had been performed without finding the diverticulum. In spite of years of medical treatment, the patient presented a new episode of lower gastrointestinal bleeding with normal colonoscopy. A new 99mTc-pertechnetate scintigraphy (including SPECT/CT) was performed and allowed the anatomical location of a Meckel's diverticulum and enabled its removal by laparoscopic radioguided surgery.

The introduction of SPECT/CT in the scintigraphic diagnostic protocol in Meckel's diverticulum increases diagnostic safety and improves lesion location. Furthermore, it favors the performance of radioguided surgery and facilitates the lesion resection, particularly when the patient has suffered previous abdominal surgery, with a more conservative procedure, reducing the morbidity associated with the surgical procedure.

Resumen

Analizamos el caso de un paciente con episodios intermitentes de hemorragia digestiva baja y sospecha de divertículo de Meckel, cuya presencia se confirmó mediante gammagrafía con 99mTc-pertecnetato. Anteriormente se había realizado laparotomía exploradora sin encontrarse el divertículo. Tras años de control con tratamiento médico, presenta un nuevo episodio de hemorragia digestiva baja con colonoscopía normal. La realización de una nueva gammagrafía con 99mTc-pertecnetato (incluyendo SPECT/TAC) permitió localizar anatómicamente el divertículo de Meckel y plantear su exéresis mediante cirugía laparoscópica radiodirigida.

La introducción de la SPECT/TAC en el protocolo diagnóstico del divertículo de Meckel incrementa la seguridad diagnóstica y mejora la localización de la lesión permitiendo la realización de cirugía radiodirigida que facilita la resección de la misma, particularmente en el caso de una reintervención, con un procedimiento más conservador, reduciendo la morbilidad relacionada con la cirugía.
