Insights

Inflammatory fibroid polyps, benign gastrointestinal tumors, can cause mechanical intestinal obstruction. This case highlights a jejunal polyp leading to intussusception in a patient with schizophrenia.

Area of Science:

  • Gastroenterology
  • Pathology
  • Surgical Oncology

Background:

  • Inflammatory fibroid polyps (IFPs) are rare, benign submucosal neoplasms of the gastrointestinal tract.
  • They are characterized by mesenchymal cells, vascular proliferation, and inflammatory infiltrate, often including eosinophils.
  • IFPs most commonly occur in the gastric antrum but can arise anywhere in the GI tract.

Observation:

  • A 48-year-old male with a history of schizophrenia presented with symptoms of mechanical intestinal obstruction.
  • Imaging revealed intussusception in the proximal jejunum.
  • Surgical exploration identified an inflammatory fibroid polyp as the lead point.

Findings:

  • The resected polyp was histopathologically confirmed as an inflammatory fibroid polyp.
  • The polyp measured X cm and was located in the proximal jejunojejunal region.
  • Microscopic examination showed characteristic features of IFP, including a proliferation of spindle cells, small blood vessels, and eosinophilic infiltration.

Implications:

  • This case underscores that inflammatory fibroid polyps, though rare, can occur in the small intestine and present as a surgical emergency.
  • Early diagnosis and surgical management are crucial for resolving intussusception and obstruction caused by IFPs.
  • Further research into the etiology and optimal management of IFPs in unusual locations is warranted.

Appendicitis-I: Introduction01:22

Appendicitis-I: Introduction

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...

Inflammatory Bowel Disease V: Surgical Management

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:

Inflammatory Bowel Disease I: Ulcerative Colitis01:27

Inflammatory Bowel Disease I: Ulcerative Colitis

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 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...

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...

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,...
