Transanal endoscopic microsurgical techniques have recently been proven a safe and effective way to remove tumors from the rectum. Patients with small (4 cm in diameter or less), early malignant tumors are candidates for TEM as are patients with benign tumors of any kind. Preoperative biopsies and staging are essential, and patient selection is key to achieving successful outcomes with these procedures. Transanal Endoscopic Microsurgery covers indications/contraindications, equipment, operative techniques, oncologic results, and an evidence-based comparison of TEM and traditional approaches. Written by the innovators of these techniques, this book is an essential reference for surgeons who want to incorporate TEM into their practice.
