Appendicitis-I: Introduction01:22

Appendicitis-I: Introduction

254
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

99
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...

Peptic Ulcer Disease III: Clinical Manifestations and Diagnostic Studies

157
Peptic ulcer disease (PUD) presents with diverse symptoms depending on the location and severity of the ulcer. Clinical manifestations of peptic ulcer include dull pain and a burning sensation in the mid-epigastric region.
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.

Assessment of the Rectum and Anus

279
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,...

Inflammatory Bowel Disease I: Ulcerative Colitis01:27

Inflammatory Bowel Disease I: Ulcerative Colitis

220
Introduction
Inflammatory bowel disease, or IBD, encompasses a group of disorders characterized by chronic inflammation or ulceration of the gastrointestinal tract.
Risk Factors
The exact cause of IBD remains unclear, although it is believed to be due to a mix of genetic, environmental, microbial, and immune factors. Genetic factors are significant in determining susceptibility to IBD, with family history being a critical risk factor. Individuals with a first-degree relative who has IBD are at...

Inflammatory Bowel Disease II: Crohn's Disease01:30

Inflammatory Bowel Disease II: Crohn's Disease

296
Introduction
Inflammatory bowel disease, commonly known as IBD, refers to a collection of disorders that lead to persistent inflammation of the gastrointestinal tract. The two types of IBD are ulcerative colitis, which impacts the colon, and Crohn's disease, which can involve any part of the gastrointestinal segment.
Crohn's disease
Crohn's disease is a chronic, systemic inflammatory bowel disease (IBD) that predominantly affects the gastrointestinal tract. It is marked by...

  • 诊断成像 诊断成像 诊断成像

背景情况:

  • 粘膜尾炎 (MA) 是一个有争议的实体,其特点是尾粘膜的有限的中性恋透.
  • 区分MA和负尾炎 (NA) 对于准确的诊断和治疗至关重要.

研究的目的:

  • 调查粘膜尾炎是否代表急性尾炎 (AA) 的早期阶段.
  • 根据临床和实验室发现,确定MA是否可以从负尾切除中区分开来.

主要方法:

  • 对1269名因疑似尾炎而接受尾切除手术的儿童 (2017-2020) 的回顾性分析.
  • 组织学分类为MA (30例) 和NA (25例) 组.
  • 群体之间的人口,临床,超声波和实验室参数的比较.

主要成果:

  • 在MA和NA组之间,在人口统计,临床或超声波特征上没有显著差异.
  • 马氏甲基组的白细胞和中性粒细胞数量以及中性粒细胞与淋巴细胞的比率 (NLRs) 显著增加 (P < .001).
  • 对于MA诊断,NLR显示了曲线下的最高面积 (0.736),截止值为3.20,提供62.5%的灵敏度和78.9%的特异性.

结论:

  • 粘膜尾炎表现出明显的实验室和组织学炎症特征,支持其被归类为急性尾炎谱内的病理实体.
  • 手术前白细胞和中性粒细胞计数,以及NLRs,可以帮助减少负尾切除术.
