Insights

Adult intussusception, often caused by metastatic malignant melanoma, requires surgical resection. This case highlights small bowel obstruction due to melanoma-induced intussusceptions, emphasizing surgical intervention for improved outcomes.

Area of Science:

  • Gastroenterology
  • Surgical Oncology
  • Medical Oncology

Background:

  • Intussusception is a rare cause of adult bowel obstruction, frequently necessitating surgical intervention.
  • Small bowel metastasis from cutaneous melanoma presents diagnostic challenges, with obstruction, hemorrhage, and peritonitis as potential clinical signs.

Observation:

  • A case of adult small bowel obstruction caused by three distinct intussusceptions is presented.
  • The intussusceptions were found to be caused by metastatic malignant melanoma.

Findings:

  • Surgical resection with free margins and adequate mesentery is the recommended treatment for intussusception due to metastatic disease.
  • Metastatic malignant melanoma can manifest as multiple intussusceptions leading to bowel obstruction.

Implications:

  • Early diagnosis and surgical management of melanoma-related intussusception are crucial for patient prognosis.
  • This case underscores the importance of considering metastatic melanoma in the differential diagnosis of adult intussusception.

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: 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...
