Final answer:
The patient who had surgery to remove part of the intestines is likely experiencing visceral pain, which is associated with pain receptors in internal organs and is typically diffuse and not easily localized.
Step-by-step explanation:
The patient who had surgery to remove part of the intestines is most likely experiencing visceral pain. This type of pain occurs when the pain receptors in the pelvic or abdominal organs are activated, often due to injury, disease, or following a surgical procedure. Unlike somatic or referred pain, visceral pain is typically more diffuse and not as easily localized, which is consistent with the description of the patient's complaint after intestinal surgery. It is worth noting that while it is possible for visceral pain to lead to referred pain, the question seems to be asking about the direct, initial type of pain the patient is feeling.
