    Insights

    Intussusception rates in Hong Kong children under 5 are higher than previously estimated. Computerized data systems can monitor these trends, accounting for readmissions and transfers.

    Area of Science:

    • Pediatric epidemiology
    • Public health surveillance

    Background:

    • Intussusception is a critical pediatric surgical emergency.
    • Accurate incidence data is vital for public health initiatives, including vaccine impact assessment.

    Purpose of the Study:

    • To evaluate intussusception incidence trends in Hong Kong.
    • To validate the accuracy of the territory's computerized discharge information system for epidemiological surveillance.

    Main Methods:

    • A retrospective review of case notes for children under 5 diagnosed with intussusception or undergoing reduction between 1997 and 2003.
    • Analysis of discharge diagnoses and procedure codes within Hong Kong's electronic health records.

    Main Results:

    • Incidence rates for infants under 1 year were 108/100,000, and for children under 5 were 38/100,000.
    • These rates exceeded prior estimates derived solely from passive discharge data.

    Conclusions:

    • Hong Kong's computerized discharge data system shows potential for intussusception surveillance.
    • Refinements are needed to account for readmissions and transfers for accurate monitoring, especially post-rotavirus vaccine introduction.

    Esophageal Strictures-II: Clinical Features and Management

    Patients with esophageal strictures often experience a range of symptoms. Initially, they may have difficulty swallowing solid foods, which can progress to include liquids. Additional symptoms may involve chest pain or discomfort, regurgitating food and fluids, heartburn, unintentional weight loss, coughing or choking during meals, and hoarseness.
    Healthcare providers should gather a comprehensive medical history and conduct a physical examination for diagnosis. If esophageal stricture is...
    Esophageal Strictures-I: Introduction01:30

    Esophageal Strictures-I: Introduction

    Esophageal strictures involve abnormal narrowing or tightening of the esophagus. They vary in length and severity, ranging from mild constriction to complete obstruction, and are classified as benign (noncancerous) or malignant (cancerous).
    Etiology
    The primary cause of esophageal strictures is long-standing gastroesophageal reflux disease (GERD), accounting for about 70 to 80% of adult cases. Chronic acid reflux can lead to injury and scarring of the esophageal lining, culminating in...
    Intestinal Obstruction I: Introduction01:29

    Intestinal Obstruction I: Introduction

    Intestinal obstruction is a partial or complete blockage of the small or large intestine that disrupts the normal flow of intestinal contents through the lumen. This interruption impairs digestion, absorption, and fluid balance, and may lead to serious complications if not treated promptly.Mechanical ObstructionMechanical obstruction occurs when a physical blockage prevents intestinal contents from passing, arising from within the lumen or the bowel wall, or from external compression.Adhesions,...
    Pyloric Obstruction01:11

    Pyloric Obstruction

    Pyloric obstruction, also referred to as gastric outlet obstruction, is a condition characterized by narrowing or blockage at the pylorus—the muscular valve regulating the flow of stomach contents into the duodenum. When this passage becomes impaired, the stomach cannot effectively empty its contents into the small intestine. This disruption leads to a range of gastrointestinal symptoms, including early satiety, bloating, epigastric pain, postprandial nausea, persistent vomiting, and...
    Intestinal Obstruction II: Pathophysiology01:07

    Intestinal Obstruction II: Pathophysiology

    Intestinal obstruction triggers a series of physiological responses, starting with gas and fluid accumulation in the bowel segment proximal to the obstruction, leading to distension. This distended intestine compresses the diaphragm, hindering lung expansion and potentially leading to reduced respiratory effort, atelectasis, and pneumonia.To overcome the blockage, the gut intensifies contractions, causing colicky abdominal pain, nausea, and vomiting, which reduces fluid and food intake and...
    Appendicitis01:19

    Appendicitis

    Appendicitis is an acute inflammatory condition of the vermiform appendix, most commonly caused by obstruction of its lumen. The appendix is a narrow, blind-ended pouch that extends from the cecum, making it particularly prone to obstruction. Causes include fecaliths, lymphoid hyperplasia (often after viral infections), parasites, tumors, or foreign bodies. This obstruction initiates a cascade of pathological changes.Luminal Obstruction and Early InflammationAfter obstruction, normal mucosal...
