ICD-10: R11.12

Projectile vomiting, classified under ICD-10-CM code R11.12, is a specific type of vomiting characterized by the forceful expulsion of stomach contents, often projecting a considerable distance. This condition can be indicative of various underlying medical issues and is important for accurate diagnosis and treatment.

Clinical Description

Definition

Projectile vomiting is defined as a sudden and forceful ejection of vomitus, which can occur without the typical retching associated with regular vomiting. This phenomenon can be alarming for patients and may suggest more serious gastrointestinal or neurological conditions.

Etiology

Projectile vomiting can arise from several causes, including but not limited to:
- Gastrointestinal Obstruction: Conditions such as pyloric stenosis, where the opening from the stomach to the small intestine is narrowed, can lead to projectile vomiting, particularly in infants.
- Increased Intracranial Pressure: Neurological issues, such as tumors or traumatic brain injuries, can cause increased pressure in the skull, leading to projectile vomiting.
- Infections: Severe infections, particularly those affecting the gastrointestinal tract, can also result in this symptom.
- Metabolic Disorders: Conditions that disrupt normal metabolic processes may lead to projectile vomiting as a symptom.

Symptoms

Patients experiencing projectile vomiting may also present with additional symptoms, including:
- Nausea
- Abdominal pain or discomfort
- Dehydration signs, such as dry mouth or decreased urine output
- Possible fever if an infection is present

Diagnosis

The diagnosis of projectile vomiting typically involves a thorough clinical evaluation, including:
- Patient History: Gathering information about the onset, frequency, and characteristics of the vomiting, as well as any associated symptoms.
- Physical Examination: Assessing for signs of dehydration, abdominal tenderness, or neurological deficits.
- Diagnostic Imaging: In some cases, imaging studies such as ultrasound or CT scans may be necessary to identify underlying causes like obstructions or tumors.

Treatment

Treatment for projectile vomiting focuses on addressing the underlying cause. This may include:
- Medications: Antiemetics to control vomiting, as well as treatments for any identified infections or metabolic imbalances.
- Surgical Intervention: In cases of obstruction, surgical procedures may be required to correct the issue.
