Appendicitis-I: Introduction01:22

Appendicitis-I: Introduction

759
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...

Appendicitis-II: Diagnostic Studies and Management

157
Diagnosing and managing appendicitis requires a structured and comprehensive approach that spans from initial assessment to postoperative care. Here is an overview of the process:
Diagnosing Appendicitis
It requires a multifaceted approach, starting with a detailed physical examination to pinpoint the location and nature of the pain and identify any associated symptoms. Laboratory tests play a crucial role. A complete Blood Count (CBC) typically reveals leukocytosis (an increased number of...

Computed Tomography01:10

Computed Tomography

6.9K
Tomography refers to imaging by sections. Computed tomography (CT) is a non-invasive imaging technique that uses computers to analyze several cross-sectional X-rays to reveal minute details about structures in the body.
The technique was invented in the 1970s and is based on the principle that as X-rays pass through the body, they are absorbed or reflected at different levels. In the technique, a patient lies on a motorized platform while a computerized axial tomography (CAT) scanner rotates...

Imaging Studies III: Computed Tomography

79
DefinitionComputed Tomography (CT) of the genitourinary (GU) tract is a non-invasive imaging modality that utilizes X-rays and computer processing to generate detailed cross-sectional images of the urinary system, encompassing the kidneys, ureters, bladder, and adjacent structures such as the adrenal glands.PurposeCT scans of the GU tract serve several diagnostic and therapeutic purposes, including:Diagnosis of Urinary Tract Diseases: Detects kidney stones, tumors, cysts, and congenital...

Assessment of the Rectum and Anus

484
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,...

Ultrasonography01:17

Ultrasonography

6.5K
Ultrasonography is an imaging technique that uses high-frequency sound waves to visualize the body's internal structures. It is a non-invasive and safe procedure that does not involve the use of ionizing radiation, making it widely used in various medical fields. Ultrasonography is used to study heart function, blood flow in the neck or extremities, certain conditions such as gallbladder disease, and fetal growth and development.
During an ultrasonography procedure, a handheld device called...

Summary
This summary is machine-generated.

A thick appendix, over 9mm in diameter, is a key indicator of acute appendicitis. Appendiceal size, white blood cell count, and age influence hospital stay duration.

Area of Science:

  • Radiology
  • Gastroenterology
  • Surgical Pathology

Background:

  • Investigated findings in adult patients diagnosed with acute appendicitis.
  • Focused on patients admitted to Cabell Huntington Hospital.
  • Utilized retrospective chart review of electronic health records.

Approach:

  • Included patients with a postoperative diagnosis of acute appendicitis and a preoperative computed tomography (CT) scan.
  • Analyzed data from January 2011 through December 2016.
  • Compared findings with CT scans of 50 trauma patients with normal abdominal scans.

Key Points:

  • A thick, edematous appendix was the most common CT finding in acute appendicitis, with an average diameter of 12.6 mm.
  • Appendiceal diameter significantly correlated with wall thickness (P < 0.001).
  • Normal appendix diameter averaged 4.9 mm (range 4-7 mm).
  • Admission white blood cell count (P = 0.0372) and appendix thickness (P < 0.0001) correlated with increased length of stay.

Conclusions:

  • An appendiceal diameter greater than 9 mm suggests acute appendicitis.
  • Appendiceal size, white blood cell count, and age are associated with length of hospital stay.
  • Early antibiotics and surgical intervention may reduce length of stay.
