Insights

Ileosigmoid knot, a rare cause of intestinal obstruction, is difficult to diagnose preoperatively. This study reports the youngest patient diagnosed with this condition, highlighting computed tomography

Area of Science:

  • Gastroenterology
  • Pediatric Surgery
  • Radiology

Background:

  • Ileosigmoid knot is a rare cause of intestinal obstruction.
  • Preoperative diagnosis is challenging, and the condition has a high mortality rate.
  • It is typically observed in adults and rarely reported in children.

Observation:

  • Two cases of ileosigmoid knot were encountered: a 4-year-old boy and a 60-year-old man.
  • Both presented with sudden abdominal pain; the child was in shock upon admission.
  • Abdominal computed tomography (CT) indicated intestinal obstruction in both patients.

Findings:

  • The 4-year-old boy represents the youngest reported case in the English literature.
  • Surgical intervention included intestinal resection for the boy and detorsion without resection for the adult.
  • Abdominal CT provided valuable diagnostic information for both ileosigmoid knot cases.

Implications:

  • This case series expands the understanding of ileosigmoid knot presentation in pediatric patients.
  • Computed tomography is a crucial imaging modality for diagnosing ileosigmoid knot.
  • Early diagnosis and surgical management are vital for improving outcomes in ileosigmoid knot.

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:
Intestinal Obstruction I: Introduction01:29

Intestinal Obstruction I: Introduction

Intestinal obstruction is a partial or complete blockage of the small or large intestine that disrupts the normal flow of intestinal contents through the lumen. This interruption impairs digestion, absorption, and fluid balance, and may lead to serious complications if not treated promptly.Mechanical ObstructionMechanical obstruction occurs when a physical blockage prevents intestinal contents from passing, arising from within the lumen or the bowel wall, or from external compression.Adhesions,...
Imaging Studies III: Gastrointestinal Motility Studies and Virtual Colonoscopy01:26

Imaging Studies III: Gastrointestinal Motility Studies and Virtual Colonoscopy

This lesson explores three gastrointestinal imaging techniques: radionuclide testing, colonic transit studies, and virtual colonoscopy.
Radionuclide Testing
Radionuclide testing is a sophisticated medical technique for assessing gastrointestinal motility. It focuses on gastric emptying and colonic transit time. Radioactive markers track the movement of food through the digestive system, providing insights into gastrointestinal disorders.
In gastric emptying studies, a meal's liquid and solid...

Endoscopic Procedures IV: Sigmoidoscopy and Laproscopy

Sigmoidoscopy and laparoscopy are distinct medical procedures that enable physicians to internally inspect different parts of the GI tract. Although they serve different purposes, each is essential for diagnosing and, in some cases, treating various medical conditions.
Sigmoidoscopy
Sigmoidoscopy is a diagnostic procedure that uses a flexible sigmoidoscope equipped with a light source and camera to examine the rectum and sigmoid colon. The procedure involves inserting the tube through the anus...
Inflammatory Bowel Disease II: Crohn's Disease01:30

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...
Histology of the Small Intestine01:27

Histology of the Small Intestine

The small intestine exhibits a unique histological structure that significantly enhances its function in digestion and nutrient absorption. These structures include circular folds, villi, and various specialized cells that collectively facilitate the digestion of food.
The intestinal lining features transverse folds called circular folds, each housing fingerlike projections known as intestinal villi. These villi are covered by a layer of simple columnar epithelium, also referred to as...
