After the removal of the intestines from the body they are opened by the intestinal shears, beginning either with the jejunum or the large intestine, the cut being made in the line of the mesenteric attachment. As the intestine is opened careful attention should be paid to the contents of each portion. It is very poor technique to dilate the intestine with water or to run water through it before it is opened. There is danger of washing away parasites, blood, etc. When the intestine is distended the opening is easy, but when collapsed it can be more easily opened if an assistant straightens it out and holds it on the stretch in advance of the enterotome. It may be opened on the table, in the tray, or in a pail. The latter method is a clean and convenient one. As the intestine is opened it is passed on the flat beneath the handle of the pail as it rests on the rim, so that the intestinal contents are scraped off into the pail and the clean mucosa examined as it is pulled from the pail into a basin or tray. The ileocæcal valve should be carefully examined from above before it is cut through. The appendix may be opened from the intestine by the small probe-pointed shears, the cut being made on the side opposite the mesenteric attachment. Transverse sections can be made, if desired. When the intestines are opened within the body, the enterotome is introduced into an opening made in the ileum just above the ileocæcal valve and the intestine is cut upward to the duodenum, along its mesenteric attachment, the coils being drawn upon the probe-pointed blade of the enterotome with the left hand. After the small intestine is opened the enterotome is introduced through the ileocæcal opening and the large intestine cut in the anterior tænia as far as the rectum. The opening of the intestine within the body should be left until all the other abdominal organs have been examined, because of the disagreeable mess made by the escape of the intestinal contents into the cavity.
