Result: 25 cases of right colectomy (16 laparotomy, 9 laparoscopy), 3 transverse colon resection (2 laparoscopy, 1 laparoscopy), 14 left colectomy (12 laparotomy, 2 laparoscopy), 21 sigmoidectomy (15 laparotomy, 6 laparoscopy), 14 low anterior resection (9 laparotomy, 5 laparoscopy) and 21 abdominoperineal resection (15 laparotomy, 6 laparoscopy). Conclusion: Laparoscopy surgery is more advantageous than laparotomy surgery.
