Final answer:
A gastrocutaneous fistula is an abnormal connection between the stomach and the skin surface. It can cause the leakage of stomach contents through the skin and may require medical or surgical intervention to close.
Step-by-step explanation:
An abnormal connection between the stomach and the skin surface would most appropriately be termed a gastrocutaneous fistula. A gastrocutaneous fistula is an opening or passage that develops between the stomach and the skin, usually as a result of surgery or trauma. It can lead to the leakage of stomach contents through the skin, causing infection and other complications.
This abnormal connection may require medical or surgical intervention to close the fistula and prevent further complications. Treatment options may include antibiotics, wound care, and surgery to repair the fistula.
Peptic ulcers, on the other hand, are sores that develop in the lining of the stomach or duodenum and are not directly related to an abnormal connection between the stomach and the skin.
