ABSTRACT Introduction: Robotic transanal surgery (RTS) is the analog of TAMIS and represents a new focus for the advancement of transanal platforms robotic transanal surgery is sometimes referred to as robotic TAMIS. Though limited to only a few centers world-wide, experience with robotic transanal surgery has been encouraging. Most research with robotic transanal surgery has concentrated on local excision of rectal neoplasia, although more complex procedures such as transanal proctectomy are possible using the robotic approach. This article reports the surgical technique of R-TAMIS performed in the Brazilian National Cancer Institute (INCA, Rio de Janeiro). Methods: 71-year-old, female with cardiologic disease (heart failure), with a 1.5 cm rectal neoplasm at 4 cm from the anal verge in the right anterolateral position. Biopsy revealed neuroendocrine tumor. A compete colonoscopy revealed no evidence of synchronous lesions. Work-up included 3D endorectal ultrasonography and magnetic resonance imaging, which demonstrated the lesion to be uT1uN0. The patient was counseled about surgical options − local excision versus low anterior resection. Due to the cardiologic condition, the patient was elected to proceed with local excision with robotic transanal surgery. Conclusion: Robotic TAMIS is a safe and effective operative procedure for high selected cases of rectal neoplasm. It enhances surgeon ergonomics and facilitates tumor removal and suture in the transanal approach.
