The =stomach= is opened from the pylorus after the size of the latter has been ascertained. The anterior wall may be cut midway between the greater and lesser curvatures, or the cut may follow the greater curvature, extending through the cardia into the œsophagus. As the stomach is opened its contents are inspected and removed. They should not be allowed to escape into the abdominal cavity. When the organs are removed _en masse_ the stomach may be opened from the cardiac end. The organ may also be opened by an incision through its posterior wall or along its lesser curvature, as occasion may demand. If it is desired to save the pyloric ring the incision may stop above or below it and begin again on the other side. The stomach, with the lower portion of the œsophagus and the superior portion of the duodenum, may be separated from their attachments and examined outside of the body. The =pancreas= is examined by turning the stomach toward the thoracic cavity, cutting or tearing the gastrocolic omentum, and cutting the exposed organ by a longitudinal incision through head, body and tail, or by means of parallel transverse incisions made through the different parts of the organ. The ducts of Wirsung and Santorini should be explored. It must be freed from the duodenum before it is weighed. The pancreas may be removed in connection with stomach, duodenum and liver and examined outside of the body. This is advisable in all cases of perforation of the stomach, ulcer, carcinoma and surgical anastomoses, carcinoma of pancreas, acute pancreatitis, obstruction of common duct, duodenal ulcer, etc.
