This is the case of a 62-year-old woman with rectal bleeding. She underwent a colonoscopy which showed a low rectal adenocarcinoma, 6cm from the anal margin. A CT-scan revealed the absence of metastasis and pelvic MRI showed a cT3N1 tumor. The patient was treated with neoadjuvant radiochemotherapy. She received 50 Gray and capecitabine after which a new MRI showed a partial tumor response. The patient underwent surgery 10 weeks after finishing neoadjuvant therapy. We started the operation with a laparoscopic abdominal approach. Four ports were placed. Two 10mm ports were introduced in the umbilicus and the right iliac fossa. Two 5mm ports were inserted in the left and right lower quadrant. Transanal total mesorectal excision (TaTME) was performed with a 5mm, 30-degree scope, monopolar hook, and bipolar forceps. The rectum was dissected 1cm distally from the neoplasia. The specimen was extracted transanally. Anastomosis was carried out transanally using a 33mm EEA™ circular stapler, after examination of the frozen section margin. A protective ileostomy was performed through the 10mm port site in the right iliac fossa and a drainage was put in place in the pelvis through the 5mm port entry site into the left flank. The patient resumed food intake on postoperative day 2 and she was discharged on postoperative day 7. A complete mesorectal excision was confirmed on pathological examination. Fifteen negative nodes were removed. Distal and circumferential margins were negative. The coloanal anastomosis was controlled with colonoscopy one month later. No sign of leakage was detected, and the ileostomy was subsequently closed. The patient reports an adequate continence to gas and feces with one or two bowel movements per day. After 15 months of follow-up, the patient is still disease-free. Our video shows that TaTME is a technique which can be performed by surgeons who have experience in laparoscopic and colorectal surgery. In our operation, we did not use any energy devices, 3D or 4K technology. This procedure can be performed without expensive equipment.
