Summary
A rare solitary Peutz-Jeghers polyp caused acute large bowel obstruction via colo-colonic intussusception in a young man. This case highlights a unique cause of intestinal obstruction, even without the full Peutz-Jeghers syndrome.
Area of Science:
- Gastroenterology
- Surgical Pathology
Background:
- Colo-colonic intussusception is a rare cause of large bowel obstruction, particularly in adults.
- Peutz-Jeghers polyps are hamartomatous polyps associated with an increased risk of gastrointestinal and extraintestinal cancers.
- Solitary colonic Peutz-Jeghers polyps are uncommon, and their role as a lead point for intussusception in adults is rarely reported.
Observation:
- A 19-year-old male presented with acute large bowel obstruction.
- Imaging studies including plain radiographs, single contrast enema, and CT scan revealed colo-colonic intussusception.
- Colonoscopy and surgical exploration identified a solitary Peutz-Jeghers polyp in the descending colon as the lead point.
Findings:
- Pathology confirmed the lead point as a solitary colonic Peutz-Jeghers polyp.
- The patient did not exhibit the full spectrum of Peutz-Jeghers syndrome.
- Correlation of clinical, imaging, endoscopic, surgical, and pathological findings was performed.
Implications:
- This case underscores the importance of considering rare causes of intestinal obstruction in young, otherwise healthy individuals.
- A solitary Peutz-Jeghers polyp can act as a lead point for intussusception, necessitating prompt diagnosis and surgical intervention.
- Further literature review is warranted to understand the full clinical spectrum and management of solitary colonic Peutz-Jeghers polyps.

01:29Intestinal 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,...
01:27Diverticular 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...
01:07Intestinal 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...
01:21Inflammatory 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:

01:19Appendicitis
Appendicitis is an acute inflammatory condition of the vermiform appendix, most commonly caused by obstruction of its lumen. The appendix is a narrow, blind-ended pouch that extends from the cecum, making it particularly prone to obstruction. Causes include fecaliths, lymphoid hyperplasia (often after viral infections), parasites, tumors, or foreign bodies. This obstruction initiates a cascade of pathological changes.Luminal Obstruction and Early InflammationAfter obstruction, normal mucosal...
01:26Histology of the Large Intestine
The large intestine, a vital component of the gastrointestinal tract, is structured with four main layers: the mucosa, submucosa, muscularis, and serosa. Each layer performs a distinct role in facilitating the smooth functioning of the large intestine.
The innermost mucosa layer comprises simple columnar epithelium, lamina propria, and muscularis mucosae. This layer is primarily populated with absorptive cells, tasked with water absorption, and goblet cells, responsible for secreting mucus to...
