| Sumario: | Introduction: Gastrointestinal stromal tumors (GISTs), the specific kit-positive mesenchymal tumors, are rarely found in the anorectum and account for 5% of all GIST cases. Surgical excision remains the main treatment for anorectal GIST. The available techniques include enucleation transanal excision or sometimes an abdominoperineal resection for large or low tumors. Case Study: We present a middle-aged female with a complaint of intermittent rectal pain for 1 year. Diagnostic workup detected a mass in the rectovaginal septum. A transvaginal excision was performed. Final histopathology showed rectal GIST. On regular follow-up visits, there was no detectable recurrence, and her anal pain disappeared completely. Discussion: Colorectal GIST accounts for only 0.1% of all colorectal tumors; this infrequency has led to a controversy in its diagnosis and management. Nevertheless, surgery remains a cornerstone element in the management of rectal GISTs. Different resection methods have been described in the literature, ranging from less-invasive approach such as transanal excision to a more radical one like an abdominoperineal resection. As there is no standard approach, choosing which one to perform depends on the tumor size, its location, and the surgeon’s preference. Conclusion: Transvaginal excision could be considered a safe minimally invasive approach for low-lying rectal GISTs. |
