Esophageal Strictures-I: Introduction01:30

Esophageal Strictures-I: Introduction

344
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...

Esophageal Strictures-II: Clinical Features and Management

215
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...

Inflammatory Bowel Disease V: Surgical Management

272
Surgical interventions for inflammatory bowel disease (IBD), which includes ulcerative colitis and Crohn's disease, are essential in managing symptoms and addressing complications. The selection of surgical procedures is contingent upon the specific conditions and complications that stem from these illnesses.
Here are some common surgical interventions for IBD:

Assessment of the Rectum and Anus01:25

Assessment of the Rectum and Anus

612
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,...

Chronic Bowel Disorders: Introduction01:17

Chronic Bowel Disorders: Introduction

588
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 I: Ulcerative Colitis

473
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...

Area of Science:

  • Gastroenterology
  • Colorectal Surgery
  • Surgical Pathology

Background:

  • Obstructive colorectal symptoms can mimic malignancy, necessitating thorough diagnostic evaluation.
  • Diverticulitis is a common condition that can present with acute abdominal symptoms.
  • The "apple core-type" mass on CT scan is often indicative of colorectal cancer.

Observation:

  • A 46-year-old male presented with a one-week history of worsening constipation, abdominal distension, nausea, and emesis.
  • CT scan revealed a sigmoid colon mass with proximal large-bowel dilation, suggestive of obstruction.
  • Sigmoidoscopy confirmed a near-obstructing sigmoid colon mass, but biopsies showed no malignancy.

Findings:

  • Final pathology after sigmoid colectomy revealed diverticulitis with abscess formation, not cancer.
  • The "apple core-type" mass was caused by severe inflammation and wall thickening from diverticulitis.
  • The patient recovered well and underwent successful colostomy reversal.

Implications:

  • This case underscores the challenge in differentiating diverticulitis from colorectal cancer based solely on imaging and initial biopsies.
  • Accurate histopathological diagnosis is crucial for appropriate management of obstructive colorectal conditions.
  • Diverticulitis can present as a colonic mass, leading to diagnostic uncertainty and potential surgical intervention.
