Irritable Bowel Syndrome II: Clinical Features and Diagnostic Evaluation
Irritable Bowel Syndrome (IBS) is classified into subtypes based on the predominant bowel habits as determined by the Bristol Stool Form Scale (BSFS). The subtypes are:

Assessment of the Rectum and Anus01:25

Assessment of the Rectum and Anus

161
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,...

Appendicitis-I: Introduction01:22

Appendicitis-I: Introduction

91
The appendix, a small, narrow, blind tube extending from the inferior part of the cecum, is widely regarded as a vestigial organ, having lost much of its original function through evolution. Despite its diminished role, the appendix can become inflamed, a condition known as appendicitis.
Etiology: Appendicitis can arise from various causes, primarily rooted in the obstruction of the appendix lumen. Factors contributing to this obstruction include fecal accumulation, lymphoid hyperplasia and, in...

Irritable Bowel Syndrome I: Introduction

252
Irritable Bowel Syndrome (IBS) is characterized by functional disturbances in the gastrointestinal system, presenting a cluster of symptoms without evident structural or biochemical abnormalities. It primarily affects the large intestine and may cause abdominal pain, bloating, excessive gas, diarrhea, constipation, or both.
IBS is a chronic condition that can persist over a long period or recur frequently.
The pathogenesis of IBS involves a complex interplay of the following factors:

Assessment of the Abdomen I: Inspection and Auscultation01:25

Assessment of the Abdomen I: Inspection and Auscultation

282
Introduction
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....

Anatomy of the Intestines01:23

Anatomy of the Intestines

71.4K
Although digestion of proteins, carbohydrates, and lipids may begin in the stomach, it is completed in the intestine. The absorption of nutrients, water, and electrolytes from food and drink also occurs in the intestine. The intestines can be divided into two structurally distinct organs—the small and large intestines.
Small Intestines
The small intestine is an ~7 meter-long tube with an inner diameter of just 2.5 cm. Since most nutrients are absorbed here, the inner lining of the...

Area of Science:

  • Pediatric Gastroenterology
  • Pediatric Oncology
  • Diagnostic Imaging

Background:

  • Infantile abdominal distension is a common presenting symptom requiring thorough evaluation.
  • Liver masses in infants can arise from various etiologies, necessitating a comprehensive diagnostic approach.

Purpose of the Study:

  • To outline the management strategy for an infant presenting with abdominal distension.
  • To detail the diagnostic workup for a liver mass in an infant, considering oncologic, vascular, and infectious causes.

Main Methods:

  • Case presentation of a 6-week-old infant with abdominal distension and fever.
  • Abdominal ultrasonography to identify a heterogeneous liver mass.
  • Further diagnostic investigations to establish a definitive diagnosis.

Main Results:

  • The infant's symptoms, including abdominal distension and fever, were indicative of an underlying liver pathology.
  • Diagnostic workup confirmed a specific etiology for the liver mass.
  • Initiation of appropriate treatment led to symptom resolution.

Conclusions:

  • Prompt evaluation of infantile abdominal distension is crucial for identifying serious underlying conditions.
  • A systematic approach to diagnosing liver masses in infants, encompassing diverse etiologies, is essential for effective management.
  • Timely diagnosis and treatment result in favorable outcomes for infants with liver masses.
