title: Laparoscopic radical resection of low rectal carcinoma integrating transanal endoscopic microsurgery: a case report.
abstract: A male patient with lower-segment rectal carcinoma underwent laparoscopic radical resection and regional lymph node dissection. The extracorporeal rectoanal anastomosis was completed using transanal endoscopic microsurgery (TEMS) without requiring any additional abdominal incision. The pathological examination identified a clean margin. At the postoperative 6-month visit, the patient exhibited generally normal defecation, urination, and sexual function, but no sign of local recurrence or distant metastasis. TEMS integrating laparoscopy is a surgically and oncologically feasible, effective, and safe procedure for lower anterior resection.
