Insights
Most children with acute abdominal pain in the emergency department observation unit (EDOU) have non-surgical causes. The EDOU is effective for monitoring pediatric patients with undiagnosed abdominal pain.
Area of Science:
- Pediatric Emergency Medicine
- Gastroenterology
- Clinical Outcomes Research
Background:
- Acute abdominal pain is a common reason for pediatric emergency department visits.
- Determining the etiology of abdominal pain in children can be challenging, necessitating observation.
- The emergency department observation unit (EDOU) offers a setting for managing these patients.
Purpose of the Study:
- To evaluate the outcomes of children admitted to the EDOU for acute abdominal pain of unclear origin.
- To identify factors influencing disposition (discharge vs. admission) in this patient population.
Main Methods:
- Retrospective cohort study of pediatric patients (≤18 years) presenting with acute abdominal pain.
- Exclusion of children with clear alternative explanations for pain.
- Analysis of disposition data and interventions using chi-squared tests.
Main Results:
- 237 children were included; 84% were discharged, and 16% were admitted.
- Only 9% of admitted patients underwent surgery, with 4% confirmed appendicitis.
- Common discharge diagnoses included abdominal pain not otherwise specified and acute gastroenteritis.
- No specific symptoms reliably predicted admission; diarrhea was associated with discharge.
Conclusions:
- The majority of pediatric EDOU admissions for abdominal pain are due to non-surgical conditions.
- The EDOU serves as a valuable setting for observing and managing children with acute abdominal pain of uncertain etiology.
Objective:
This study aimed to determine the outcome of children with unclear etiology for acute abdominal pain admitted to the emergency department observation unit (EDOU).
Methods:
This is a retrospective cohort study of children 18 years or younger who presented with acute abdominal pain to a tertiary pediatric ED and were observed in the EDOU. Children with alternative explanations for abdominal pain were excluded. Patients were classified based on disposition, and data were analyzed using χ tests.
Results:
There were 237 patients included in the study (median age, 9 years; 46% male). Mean length of stay in EDOU was 14.4 hours. Fifty-four percent were evaluated by surgery. Two hundred (84%) were discharged; 37 (16%) were admitted, of whom 22 (9%) underwent surgical intervention (13 appendectomies, 6 ovarian cystectomies, 2 small-bowel obstructions, 1 cholecystectomy). Eight had acute appendicitis on pathology reports. The duration of symptoms, the presence of fever, nausea/vomiting, right-lower-quadrant pain, rebound tenderness, or leukocytosis greater than 10,000 cells/μL did not predict admission. Patients with diarrhea were more likely to be discharged home (P = 0.02). Intravenous hydration (86%) and pain control (63%) were the most common interventions in the EDOU. Abdominal pain not otherwise specified and acute gastroenteritis were the 2 most common discharge diagnoses. Eight (4%) of the 200 discharged patients returned to the ED within 48 hours, and all were discharged home from the ED.
Conclusions:
The majority of children admitted to the EDOU with abdominal pain have nonsurgical causes of abdominal pain. The EDOU provides a reasonable alternative for monitoring these patients pending disposition.

Assessment of the Abdomen I: Inspection and Auscultation
The abdominal examination is a cornerstone of clinical medicine, serving as a critical tool in diagnosing various gastrointestinal (GI) diseases. It involves a systematic approach that includes inspection and auscultation, each with distinct yet complementary roles in assessing the abdomen. This article will delve into these two primary methods healthcare professionals use to examine the abdomen.
Inspection of the Abdomen
The first step in any abdominal examination is inspection.
Peptic Ulcer Disease III: Clinical Manifestations and Diagnostic Studies
Few clinical manifestations differentiate gastric ulcers from duodenal ulcers. Distinctions in the location, timing, and pain relief are crucial for healthcare providers in differentiating between gastric and duodenal ulcers during clinical assessments.
