RESUMEN
ABSTRACT: The purpose of this article is to describe the activities developed within the framework "Regional Workshop on Optimization of Protection in Pediatric Interventional Radiology in Latin American and Caribbean countries," developed between October 16th and 19th of the year 2023 in the city of San José, Costa Rica. The workshop was carried out as part of a joint work between the Pan American Health Organization (PAHO) and the World Health Organization (WHO), in cooperation with the International Atomic Energy Agency (IAEA). The main objective of the regional workshop was to gather the experiences and future work planning among participants in the Optimization of Protection in Pediatric Interventional Radiology in Latin America and the Caribbean (OPRIPALC) program. It involved professionals from 14 centers across 11 countries in the region, along with 4 experts from PAHO/WHO/IAEA. The work modalities during the workshop consisted of keynote presentations, individual presentations, group work, and general discussions. An online survey was carried out after the workshop, with the objective of knowing the opinion of the event participants and determining the impact and projection of the OPRIPALC program. During the workshop the centers had to present their experiences: the use of the DOLQA dose management system was presented and work was done on the consensus document on good practices. The activities, topics and organization of the workshop were valued positively by the participants. There is unanimity among the centers that the OPRIPALC program has had a positive impact and they wish to continue actively participating in the next biennium.
RESUMEN
OBJECTIVE: To describe a rare case of gastrointestinal stromal tumor (GIST) outside the gastrointestinal tract and arising in the rectovaginal septum with literature review. CASE: This study involved a 29-year-old woman, gravida 0, with a GIST presenting as an asymptomatic tumor in the rectovaginal septum. The tumor was excised locally, and the patient received imatinib as adjuvant therapy. She is free of disease 2 years after surgery. CONCLUSIONS: To our knowledge, only 5 cases of GIST presenting as rectovaginal mass have been reported previously. Local excision is the definitive treatment and the use of imatinib shows promising results. Mitotic activity, cellularity, and necrosis are the main prognostic factors. Long-term follow-up is necessary.Different physicians involved in the evaluation of a mass arising in the rectovaginal septum should be alert of GIST as differential diagnosis, even in young women.
