Tension pneumoperitoneum after intussusception pneumoreduction

High risk and low incidence diseases: Pediatric intussusception

INTRODUCTION

Pediatric intussusception is a serious condition that carries with it a high risk of morbidity and mortality.

OBJECTIVE

This review highlights the pearls and pitfalls of pediatric intussusception, including the presentation, diagnosis, and management in the emergency department (ED) based on current evidence.

DISCUSSION

Intussusception is one of the most common pediatric abdominal emergencies. This is associated with one part of the intestine telescoping into another, resulting in bowel edema. If the intussusception remains untreated, obstruction, ischemia, necrosis, and perforation may result. Most cases are idiopathic, with 10-25 % associated with a pathologic mass or lead point. The most common age group affected includes those between 3 months to 5 years. The triad of intermittent abdominal pain, currant jelly stool, and sausage-shaped mass is uncommon, though most patients will present with intermittent abdominal pain. Nonbilious emesis and bloody stools (gross blood or guaiac positive) are also common. Younger patients can present atypically, including altered mental status or lethargy. Thus, intussusception should be considered in pediatric patients with abdominal pain, emesis, and a sausage-shaped mass, as well as those with atypical presentations such as altered mental status or lethargy if there is no other etiology found on testing. The diagnostic modality of choice is ultrasound. Plain radiography may assist in evaluating for obstruction and perforation. Treatment includes prompt reduction of the intussusception. In patients who are stable and have no evidence of perforation, non-operative reduction with hydrostatic or pneumatic reduction should be attempted. Operative intervention is necessary in those who are unstable, peritonitic, or have a focal lead point. Discharge may be appropriate for patients following successful non-operative reduction if the patient is able to tolerate clear fluids, is asymptomatic, and can return for any recurrence of symptoms.

CONCLUSION

An understanding of pediatric intussusception and its many potential mimics can assist emergency clinicians in diagnosing and managing this high risk disease.

Gastric rupture with pneumoperitoneum after mouth-to-nose breathing in an infant

BACKGROUND

Gastric rupture with resulting tension pneumoperitoneum occurs rarely in infants. It may be associated with resuscitative efforts.

OBJECTIVES

This report presents a unique case of gastric rupture and illustrates the factors necessary for prompt recognition and treatment.

CASE REPORT

The patient was a 16-week-old infant with nasal congestion whose father had attempted to clear her nose by a mouth-to-mouth-and-nose maneuver. The alert and attentive patient presented to the Emergency Department in respiratory distress, with marked abdominal distention. She was diagnosed with a massive tension pneumoperitoneum, which was decompressed by needle aspiration. A laceration of the lesser curvature of the stomach was repaired at laparotomy; the patient recovered uneventfully.

CONCLUSION

Tension pneumoperitoneum is rarely seen but has key defining elements. A simple procedure is critical to relief of the condition.
