Choose a pediatric, adult, or older adult age population and a diagnosis that you have the least knowledge that presents as an acute abdomen. Using the textbook and an additional scholarly reference, identify the diagnosis, discuss the subjective and objective data, and any specific physical examination techniques or diagnostic studies that are pathognomonic for this condition.

Introduction:

An acute abdomen is a medical emergency characterized by sudden and severe abdominal pain. It requires prompt diagnosis and intervention as it may be caused by a variety of underlying conditions, some of which can be life-threatening. In this assignment, we will focus on the pediatric population and a specific diagnosis that presents as an acute abdomen. The chosen diagnosis for this discussion is intussusception, a condition that occurs primarily in infants and young children.

Intussusception:

Intussusception is a telescoping or invagination of one portion of the intestine into another, leading to bowel obstruction. It is the most common cause of intestinal obstruction in children between the ages of 3 months and 6 years (Stollman & Newman, 2014). The exact cause of intussusception is unknown, but it is often associated with viral infections or lymphoid hyperplasia (Stollman & Newman, 2014).

Subjective Data:

The subjective data obtained from the patient or caregiver is crucial in assessing intussusception. Caregivers may report symptoms that initially appear non-specific, such as the child being fussy, irritable, or having periods of inconsolable crying. As the condition progresses, more specific symptoms may present, including sudden onset of severe abdominal pain, drawing of legs toward the abdomen, and episodes of pallor or flushing (Cope, 2018).

Objective Data:

The objective assessment of a patient with suspected intussusception involves a comprehensive physical examination. The abdomen should be carefully inspected for any visible signs of distension, asymmetry, or abnormal peristaltic waves. Abdominal palpation may reveal a sausage-shaped mass in the right upper quadrant or upper mid-abdomen, which represents the intussuscepted bowel (Cope, 2018).

Auscultation of the abdomen may reveal decreased or absent bowel sounds, indicating possible bowel obstruction. It is important to note that while these physical findings can be suggestive of intussusception, they are not pathognomonic of the condition and may be present in other abdominal pathologies as well.

Diagnostic Studies:

Imaging studies play a crucial role in confirming the diagnosis of intussusception. The first-line imaging modality for suspected cases is an ultrasound examination of the abdomen. Ultrasound is non-invasive and can provide real-time imaging of the intestine, allowing for visualization of the intussusception and assessing its location, length, and reduction (Stollman & Newman, 2014).

During the ultrasound examination, a target sign or doughnut sign may be visualized, representing the intussusception. Additionally, the presence of mesenteric lymph nodes or ascites may be suggestive findings (Cope, 2018). It is important to note that although ultrasound is highly sensitive and specific for intussusception, it is operator-dependent, and experienced sonographers are required to obtain accurate results.

In some cases where ultrasound findings are equivocal or not available, further diagnostic testing such as a contrast enema may be necessary. A contrast enema involves the administration of contrast material into the rectum and colon, which helps to identify and reduce the intussusception by hydrostatic pressure (Cope, 2018). The reduction of the intussusception may be visualized during the procedure, further confirming the diagnosis.

Conclusion:

Intussusception is a condition that primarily affects infants and young children, leading to bowel obstruction. Prompt diagnosis is essential as delay in treatment can result in bowel ischemia, perforation, and peritonitis. The subjective and objective data, along with specific physical examination techniques and diagnostic studies, play a vital role in identifying and confirming the diagnosis of intussusception.

Subjective data obtained from caregivers may include non-specific symptoms such as irritability and inconsolable crying, progressing to more specific symptoms of severe abdominal pain and leg drawing. Objective assessment involves thorough abdominal examination, looking for distension, asymmetry, abnormal peristaltic waves, and palpating for the presence of a sausage-shaped mass.

Imaging studies, particularly ultrasound, are the mainstay for diagnosing intussusception. Visualization of a target or doughnut sign on ultrasound is suggestive of the condition. If ultrasound results are equivocal or unavailable, a contrast enema can be performed to further confirm the diagnosis by visualizing the reduction of the intussusception.

Overall, a comprehensive knowledge of intussusception’s presentation, physical findings, and diagnostic studies is crucial to provide timely and appropriate management for children presenting with an acute abdomen.
