40 Questions
What is an incisional hernia?
An incisional hernia is caused by a defect in the abdominal musculature that develops after a surgical incision, resulting in a protrusion in the area of the surgical scar.
What does protrusion of the navel indicate?
Protrusion of the navel indicates an umbilical hernia.
What can happen if a hernia is nonreducible or incarcerated?
If a hernia is nonreducible or incarcerated, the blood supply to the protruded contents may become obstructed and require immediate surgery.
When may diastasis recti become apparent?
Diastasis recti may become apparent when the patient raises his or her head from the table.
What causes a diaphragmatic hernia?
A diaphragmatic hernia occurs when there is a defect in the diaphragm that allows abdominal contents to move into the chest cavity.
How can you determine the size of an umbilical hernia?
Measure the diameter of the umbilical opening rather than the protruding contents.
At what age do most umbilical hernias close spontaneously?
By 1 to 2 years of age.
What is diastasis rectus abdominis?
A separation 1 to 4 cm wide in the midline between the xiphoid and the umbilicus.
What should be considered if an infant is vomiting frequently?
Peristaltic waves observed in the abdomen.
When does the maximum size of an umbilical hernia generally occur?
By 1 month of age.
What are some signs of an umbilical hernia that the examiner should look for during the physical examination?
Inflammation, swelling, or bulge
What is the significance of periumbilical discoloration (Cullen sign) during the examination?
It suggests intra-abdominal bleeding
What is the term for the pearl-like, enlarged and sometimes painful umbilical nodule that can be the first sign of an intra-abdominal malignancy?
Sister Mary Joseph's nodule
What are some possible causes of generalized symmetric distention of the abdomen?
Obesity, enlarged organs, fluid, or gas
What can cause distention from the umbilicus to the symphysis?
Ovarian tumor, pregnancy, uterine fibroids
What are three common causes of paralytic ileus?
Diuretics, narcotics, hypothyroidism
How can a patient on diuretics for hypertension develop a paralytic ileus?
Hypokalemia
What physical maneuver can help reveal previously unseen bulges or masses in the abdomen?
Asking the patient to take a deep breath and hold it
What does it indicate if a patient's abdomen is significantly distended with hypoactive bowel sounds and diminished deep tendon reflexes?
Possible paralytic ileus
How can you differentiate between an umbilical hernia and an incisional hernia?
Umbilical hernias occur at the umbilicus, while incisional hernias occur at the site of a previous surgical incision
What is a common finding in infants characterized by the protrusion of omentum and intestine through the umbilical opening?
Umbilical hernia
What term is used to describe the protrusion of abdominal contents through a defect in the abdominal wall at the site of a surgical scar?
Incisional hernia
What type of hernia is characterized by a protrusion of abdominal contents through a defect in the diaphragm?
Diaphragmatic hernia
What is a possible diagnosis when there is a nodule of granulomatous tissue in the folds of skin in the umbilicus?
Paralytic ileus
What should alert you to the possibility of congenital anomalies when inspecting the umbilical cord of a newborn?
A single umbilical artery
What is the difference between an umbilical hernia and an incisional hernia?
Umbilical hernia occurs at the belly button, while incisional hernia occurs at the site of a previous surgical incision.
Explain the mechanism behind a diaphragmatic hernia.
A diaphragmatic hernia occurs when there is a hole in the diaphragm, allowing abdominal organs to move into the chest cavity.
What is the main risk associated with a paralytic ileus?
The main risk with paralytic ileus is the potential for bowel perforation due to the lack of movement within the intestines.
How does peristalsis affect the movement of food in the alimentary tract?
Peristalsis is a wave-like muscle contraction that propels food along the digestive tract through rhythmic contractions and relaxations.
What are the protective functions of the mesentery in the abdominal cavity?
The mesentery covers most of the small intestine and anchors it to the posterior abdominal wall, providing protection and support.
What is the difference between a paralytic ileus and a mechanical obstruction in the intestine?
Paralytic ileus is caused by decreased or absent intestinal motility, while a mechanical obstruction is caused by a physical blockage in the intestine.
Explain the pathophysiology of a diaphragmatic hernia.
A diaphragmatic hernia occurs when abdominal organs move into the chest cavity through a defect in the diaphragm.
What are the risk factors for developing an umbilical hernia?
Risk factors for developing an umbilical hernia include obesity, multiple pregnancies, and chronic coughing.
How does an incisional hernia differ from other types of hernias?
An incisional hernia occurs at the site of a previous surgical incision, while other hernias may develop in different areas of the abdominal wall.
What are the signs and symptoms of a strangulated hernia?
Signs and symptoms of a strangulated hernia include severe abdominal pain, nausea, vomiting, and discoloration of the overlying skin.
How is an umbilical hernia diagnosed?
An umbilical hernia is typically diagnosed based on physical examination, where a bulge is felt near the umbilicus.
Discuss the potential complications of an untreated diaphragmatic hernia in infants.
Untreated diaphragmatic hernia in infants can lead to respiratory distress, lung hypoplasia, and even death.
What are the treatment options for an incarcerated umbilical hernia?
Treatment for an incarcerated umbilical hernia involves manual reduction or surgical repair to prevent strangulation.
Explain the role of the ileocecal valve in the prevention of backward flow of fecal material.
The ileocecal valve acts as a one-way valve that prevents the reflux of fecal contents from the large intestine into the small intestine.
How does a paralytic ileus differ from an obstruction caused by adhesions?
A paralytic ileus results from decreased motility without a physical blockage, while an obstruction due to adhesions involves a mechanical blockage caused by scar tissue.
