A gastric band for laparoscopic gastric restrictive surgery includes a band (1) having a latch portion (11) and a latch element (12) which is fixed to the latch portion (11) when the band is encircled. A filler bag (2) is disposed on the inner circumferential surface of the band (1). A protecting saddle (3) extends axially from the lateral end of the band (1) and is located corresponding to the filler bag (2). For gastric band plicaton, the stomach is plicated to form a large gastric pouch and a plicated portion. For laparoscopic sleeve gastrectomy, a part of the stomach is removed to form the stomach to be a small sleeve shape, and the incision location is sewed. The filler bag (2) is covered below the connecting position of the patients stomach and esophagus by the band (1), and the protecting saddle (3) is covered onto the plicated portion or incision location to prevent the patient from overeating.
