Abstract

Insights

Intussusception caused by rare intestinal hemangiomas and appendiceal mucinous neoplasms presents diagnostic challenges. Early surgical intervention is crucial for favorable outcomes in these uncommon cases.

Area of Science:

  • Gastroenterology
  • Surgical Oncology
  • Pathology

Background:

  • Intussusception is rarely caused by intestinal hemangiomas or appendiceal mucinous neoplasms.
  • Co-occurrence of intestinal hemangiomas and low-grade appendiceal mucinous neoplasms (LAMNs) is exceptionally rare.

Observation:

  • A 47-year-old male presented with acute abdominal pain and bloating.
  • CT scan suggested secondary intussusception of the ascending colon.
  • Histopathology confirmed a mixed hemangioma with LAMNs, leading to intestinal obstruction.

Findings:

  • The patient underwent successful laparotomy and right hemicolectomy.
  • Post-operative follow-up of 4 months showed no disease progression.

Implications:

  • Non-specific symptoms complicate preoperative diagnosis of these rare conditions.
  • Delayed diagnosis or treatment can lead to intestinal necrosis, peritonitis, or pseudomyxoma peritonei.
  • Prompt diagnosis and surgical management are vital for improving patient prognosis.

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...

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,...

Appendicitis-II: Diagnostic Studies and Management

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...

Anatomy of the Intestines01:23

Anatomy of the Intestines

Although digestion of proteins, carbohydrates, and lipids may begin in the stomach, it is completed in the intestine. The absorption of nutrients, water, and electrolytes from food and drink also occurs in the intestine. The intestines can be divided into two structurally distinct organs—the small and large intestines.
Small Intestines
The small intestine is an ~7 meter-long tube with an inner diameter of just 2.5 cm. Since most nutrients are absorbed here, the inner lining of the...

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 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...
