A

acute cholecystitis

24
Q

Rovsing sign is suggestive of

A

acute appendicitis

25
Q

What is cullen sign?

A

periumbilical darkening of skin from blood

A physical examination characterized by periumbilical ecchymosis and bluish-red discoloration. Can be seen in any disease that causes retroperitoneal hemorrhage (e.g., ruptured abdominal aortic aneurysm). Classically associated with pancreatitis.

26
Q

What is cullen sign suggestive of?

A

Hemoperitoneum

*A physical examination characterized by periumbilical ecchymosis and bluish-red discoloration. Can be seen in any disease that causes retroperitoneal hemorrhage (e.g., ruptured abdominal aortic aneurysm). Classically associated with pancreatitis.

27
Q

Flexion of right thigh at right angles to trunk and external rotation of same leg in supine position results in hypogastric pain is called what sign?

A

obturator

28
Q

obturator sign is indicative of

A

appendicitis, pelvic abscess, inflammatory mass

29
Q

Left shoulder pain when patient is supine or in trendelenburg

A

Kehr sign

A referred pain to the left shoulder as a result of irritation of the left hemidiaphragm. Occurs because both left phrenic nerve, which innervates the left hemidiaphragm, and the left supraclavicular nerves, which innervate the skin over the shoulder, have common cranial nerve roots (C3 and C4). Most common cause is splenic injury.

30
Q

what is Kehr sign indicative of?

A

hemoperitoneum

A referred pain to the left shoulder as a result of irritation of the left hemidiaphragm. Occurs because both left phrenic nerve, which innervates the left hemidiaphragm, and the left supraclavicular nerves, which innervate the skin over the shoulder, have common cranial nerve roots (C3 and C4). Most common cause is splenic injury.

31
Q

Parietal Pain

A

Where the peritoneum touches the abdominal wall, called the parietal peritoneum, it is somatically innervated and produces parietal pain.

Parietal pain, like somatic pain, is punctate, localizable, and sharp.

32
Q

Pain that is punctate, localizable, and sharp

A

Somatic and Parietal Pain

33
Q

Most abdominal pain can be narrowed down to what 4 major mechnisms?

Q

What are some cardiovascular causes of acute abdomen?

A

ACS, Acute Mesenteric Ischemia, AAA/aortic dissection

37
Q

A full-thickness injury of the wall of the gastrointestinal tract that results in leakage of enteric contents. Causes include direct trauma (e.g., penetrating injury) and ischemia (e.g., due to bowel obstruction).
