Insights

Pediatric anismus, a cause of chronic constipation, is diagnosed using colon barium contrast and anorectal manometry. The Lynn procedure offers a surgical option for patients unresponsive to conservative treatments like toilet training.

Area of Science:

  • Pediatric Gastroenterology
  • Colorectal Surgery

Context:

  • Idiopathic chronic constipation in children can be linked to anismus.
  • Accurate diagnosis is crucial for effective management.

Purpose:

  • To investigate diagnostic methods and treatment outcomes for pediatric anismus.
  • To evaluate the efficacy of the Lynn procedure in refractory cases.

Summary:

  • Retrospective analysis of 29 pediatric patients diagnosed with anismus via colon barium contrast and anorectal manometry.
  • Initial treatment involved toilet training, diet modification, and laxatives, with limited success. Four patients underwent the Lynn procedure, showing positive outcomes.
  • Diagnostic tools include history, colon barium contrast, and anorectal manometry, with rectoanal inhibitory reflex (RAIR) assessment. The Lynn procedure is a viable option for treatment-resistant cases.

Impact:

  • Highlights the importance of specific diagnostic criteria for pediatric anismus.
  • Suggests the Lynn procedure as a potential surgical intervention for severe or persistent cases.
  • Provides insights into the long-term effects of the Lynn procedure on anorectal manometry parameters.

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...

Aneurysm III: Interprofessional Care

Aneurysm management involves either conservative medical therapy or surgical intervention, depending on the size and symptoms of the aneurysm. Conservative management is generally reserved for smaller, asymptomatic aneurysms, while larger or symptomatic aneurysms often necessitate surgical repair.Conservative Medical TherapyFor small, asymptomatic aneurysms, particularly abdominal aortic aneurysms (AAA) less than 5.5 centimeters in diameter, conservative medical therapy is recommended. This...

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...

Assessment of the Rectum and Anus

Evaluating the rectum and anus plays a crucial role in conducting a thorough physical examination of the gastrointestinal system. Although it may be uncomfortable and often embarrassing for the patient, it holds immense diagnostic value, particularly in detecting gastrointestinal diseases and abnormalities. This guide will explain how to perform this assessment using inspection and palpation methods.
Rectal Inspection
Begin by inspecting the perianal and anal areas for color, texture, rashes,...
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...

Aneurysm II: Clinical Manifestations and Diagnostic Studies

Thoracic, aortic arch and abdominal aneurysms are significant vascular conditions that can present with various clinical manifestations and lead to serious complications. Understanding these manifestations and the appropriate diagnostic studies is essential for effective management and treatment.Thoracic Aortic AneurysmsThoracic aortic aneurysms often remain asymptomatic until they reach a size that impinges on adjacent structures. They typically cause deep, diffuse chest pain that radiates to...
