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,...
Intestinal Obstruction II: Pathophysiology01:07

Intestinal Obstruction II: Pathophysiology

Intestinal obstruction triggers a series of physiological responses, starting with gas and fluid accumulation in the bowel segment proximal to the obstruction, leading to distension. This distended intestine compresses the diaphragm, hindering lung expansion and potentially leading to reduced respiratory effort, atelectasis, and pneumonia.To overcome the blockage, the gut intensifies contractions, causing colicky abdominal pain, nausea, and vomiting, which reduces fluid and food intake and...
Diverticular Disease of the Colon01:27

Diverticular Disease of the Colon

Diverticular disease involves the formation of diverticula—small sac-like outpouchings of the colonic wall—and their complications. It most commonly affects the sigmoid colon due to higher intraluminal pressure and structural vulnerability. It results from structural weakness and increased pressure in the colon, producing pseudodiverticula that may remain silent or progress to inflammation and serious complications.Structure of DiverticulaIn diverticulosis, these outpouchings are...
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 small...

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: 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...

Summary
This summary is machine-generated.

Adult intestinal intussusception is rare, often diagnosed during surgery, and frequently linked to malignancy. Resection is recommended due to the high incidence of tumors, with a 5% mortality rate observed in this study.

Area of Science:

  • Gastroenterology
  • Surgical Oncology
  • Abdominal Surgery

Context:

  • Intestinal intussusception, a condition where one part of the intestine telescopes into another, is uncommon in adults compared to children.
  • This study examines adult cases to clarify clinical presentation, diagnosis, and outcomes.

Purpose:

  • To determine the clinical presentation, diagnostic methods, and outcomes of adult intestinal intussusception.
  • To compare findings with existing literature and highlight diagnostic challenges.

Summary:

  • A retrospective review of 20 adult patients (mean age 40) with intestinal intussusception treated surgically between 1982 and 1999.
  • Abdominal pain was the primary symptom (90%). Preoperative diagnosis was achieved in only 30% of cases.
  • Tumors were present in 12 patients. Surgical management varied based on location, with resection being common, especially for colonic intussusceptions. Mortality was 5%.

Impact:

  • Highlights the diagnostic difficulty of adult intussusception, often requiring intraoperative confirmation.
  • Emphasizes the association with malignancy in adults, supporting surgical resection as the primary treatment.
  • Provides data on surgical outcomes and mortality for adult intestinal intussusception.
