¢A patient undergoes a total gastrectomy because of a proximally located gastric cancer. After the surgery, which of the following digestive enzymes will be produced in inadequate amounts?
A. Amylase B. Chymotrypsin C. Lipase D. Pepsin E. Trypsin

The correct answer is D. Pepsin is secreted by the chief cells of the stomach. Pepsinogen is activated by contact with stomach acid.
Gastric cancer is treated with surgical resection when it is regionally confined. Total gastrectomy is recommended for proximal tumors. Patients who have distal gastric cancers are able to have similar outcomes with subtotal gastrectomy. Adjunctive perioperative chemoradiation or perioperative chemotherapy is done for later stage disease. The stomach secretes pepsin (chief cells), gastrin (G-cell stimulation), pepsinogen (G-cell stimulation), and hydrochloric acid as initial means for digestion of food substances. |
