RESUMO
Gastrointestinal stromal tumors (GISTs) are a type of mesenchymal tumors. They are rare in rectum. This location is a surgical challenge due to the high morbidity after aggressive surgeries. We present the case of an 81-year-old female with a high-grade GIST treated with transvaginal excision and adjunctive therapy with imatinib. The postoperative period was uneventful without anal dysfunction. Within the types of surgical treatment available, transvaginal excision is an acceptable procedure in lesions located in the rectovaginal region.
RESUMO
Mesenteric laceration is an uncommon cause of hemoperitoneum, with nonspecific signs and symptoms and frequently is camouflaged by the signs of other traumatic lesions. There is a high risk to go unnoticed increasing morbidity and mortality. We report a case of a 43-year-old man, who was involved in a motorcycle accident, with thoraco-abdomino-pelvic trauma, but without evidence of intra-abdominal lesions on exams, with exception of hemoperitoneum. Due to hemodynamic instability, it was performed an exploratory laparotomy. Intraoperative findings were mesenteric lacerations affecting a small bowel segment. This case demonstrates that a high index of suspicion is necessary to diagnose and treat lesions like mesenteric laceration, not visible early on imaging but potentially fatal, with high risk of complications.
