GASTRIC DIGESTION. 343 When it is certain that all the bleeding has stopped, the peritoneum is to he opened upon a director. On stretching open the wound the distended stomach comes into view, its oblique muscular structure being plainly visible through its serous covering. The gastric wall should then be seized with a pair of artery forceps at a point where there are not many vessels and drawn forward. Two strong silk threads are then passed into the walls of the stomach with a curved needle, at distances from each other about equal to the diameter of the tube of the cannula, and brought out again at a similar distance from the points where they were introduced. An incision is then made into the gastric walls, between the two threads, rather shorter than the diameter of the tube of the cannula. Im- mediately some bubbles of gas escape and some of the fluid contents of the stomach, which must be sponged off. The opening into the stomach is now to be stretched with a pair of blunt hooks until it is large enough to pass the inner flange of the cannula, which is to be then introduced and pushed into the stomach up to its outer plate. The form of the cannula usually employed is repre- sented in Fig. 145 ; it consists of two tubes, each ter- minating at one end in a circular plate, the two tubes being cut with a screw-thread, on the outside of one and the interior of the other, so that the distance be- tween the two plates, when the tubes are joined together, may be altered at will. After the insertion of the cannula the stomach is fastened to it by the threads which were previously inserted, and the ends of these threads passed through the abdominal walls in such a way as to fasten the stomach to them, and at the same time when tied together keep the edges of the wound in the abdominal walls in apposition.
