The direct cause of peptic ulcers is thedestruction of the gastric or intestinal mucosallining of the stomach by hydrochloric acid, an
acid normally present in the digestive juices ofthe stomach. Infection with thebacterium Helicobacter pylori is thought toplay an important role in causing both gastric
and duodenal ulcers. Helicobacter pylori maybe transmitted from person to person throughcontaminated food and water.

Acute appendicitis is treated by surgery to removethe appendix. The operation may be performedthrough a standard small incision in the rightlower part of the abdomen, or it may be performedusing a laparoscope. In some patients, laparoscopyis preferable to open surgery because the incisionis smaller, recovery time is quicker, and less painmedication is required. The appendix is almostalways removed, even if it is found to be normal.With complete removal, any later episodes of painwill not be attributed to appendicitis.
