Assessment of the Rectum and Anus01:25

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,...

Skin Diseases and Disorders

Skin is the first line of defense and encounters a variety of microbes. Some pathogenic strains are often the cause of a broad range of infections of the skin and other body systems. These conditions can affect people of all ages and may have different causes, including genetic factors, infections, autoimmune reactions, environmental factors, and lifestyle choices.
Gram-positive Staphylococcus spp. and Streptococcus spp. are responsible for many of the most common skin infections. However, many...
Inflammatory Bowel Disease I: Introduction01:26

Inflammatory Bowel Disease I: Introduction

Inflammatory bowel disease is a group of chronic disorders marked by recurrent inflammation of the gastrointestinal tract due to an abnormal immune response against gut microflora. This leads to tissue damage. The two main forms are Crohn’s disease and ulcerative colitis.Crohn’s DiseaseCrohn’s disease is a relapsing inflammatory disorder that can affect any part of the GI tract, from the mouth to the anus. It involves all layers of the bowel wall (transmural) and shows “skip lesions” in which...
Skin Cancer01:30

Skin Cancer

Skin cancer is a type of cancer that occurs when there is an abnormal growth of skin cells, usually triggered by damage to the DNA within the skin cells. It is primarily caused by exposure to ultraviolet (UV) radiation from the sun or artificial sources like tanning beds. Skin cancer is the most common type of cancer worldwide, and its incidence continues to rise.
Basal Cell Carcinoma (BCC): BCC is the most common type of skin cancer, accounting for about 80% of cases. It typically develops in...
Chronic Bowel Disorders: Introduction01:17

Chronic Bowel Disorders: Introduction

Chronic bowel diseases are a group of long-term conditions affecting the digestive tract, characterized by inflammation and damage to the gut lining. These conditions primarily include irritable bowel syndrome and inflammatory bowel disease.
Irritable Bowel Syndrome (IBS) is a common disorder affecting the gastrointestinal tract. The distinctive feature is recurrent abdominal pain associated with altered bowel movements, manifesting as constipation, diarrhea, or fluctuating between both. The...

Inflammatory Bowel Disease II: Crohn's Disease

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 transmural...

Area of Science:

  • Colorectal Surgery
  • Dermatology
  • Pathology

Background:

  • Perianal dermatosis presents a wide spectrum of conditions, ranging from benign eczematous issues to advanced malignancies.
  • Accurate differentiation of these lesions is crucial for effective colorectal surgical management.
  • This review focuses on non-sexually transmitted diseases within the intergluteal fold and perianal region.

Purpose of the Study:

  • To provide colorectal surgeons with a guide for distinguishing common perianal dermatoses from more severe pathologies.
  • To review various non-sexually transmitted conditions affecting the perianal and intergluteal areas.
  • To enhance diagnostic capabilities for conditions encountered in colorectal practice.

Main Methods:

  • Literature review of non-sexually transmitted diseases affecting the perianal region.
  • Categorization of conditions including inflammatory dermatoses, infections, and other disease processes.
  • Emphasis on clinical presentation and diagnostic considerations for colorectal surgeons.

Main Results:

  • Common inflammatory dermatoses, such as eczema and psoriasis, are frequently encountered.
  • Bacterial and fungal infections represent significant differential diagnoses in perianal lesions.
  • Other conditions, including benign growths and early malignancies, require careful evaluation.

Conclusions:

  • Distinguishing benign from malignant perianal dermatoses is essential for timely and appropriate surgical intervention.
  • Understanding the differential diagnosis of non-sexually transmitted perianal conditions improves patient outcomes.
  • This review serves as a practical resource for colorectal surgeons managing perianal skin pathology.
