Summary
Adult intussusception is rare, often caused by tumors. This case details a 30-year-old woman with ileocolic intussusception due to a large cecal lipoma, highlighting a rare cause of bowel obstruction.
Area of Science:
- Gastroenterology
- Surgical Oncology
- Abdominal Imaging
Background:
- Intussusception in adults is uncommon, with benign or malignant tumors frequently serving as the lead point.
- Lipomas are rare benign tumors of the large intestine, infrequently identified as a cause of intussusception.
Observation:
- A 30-year-old female presented with two weeks of abdominal pain, diagnosed via CT scan with ileocolic intussusception.
- The intussusception's lead point measured 6.7 cm, appearing predominantly fatty on imaging.
- Colonoscopy revealed a large, obstructing lesion in the transverse colon.
Findings:
- Exploratory laparotomy confirmed a large lipoma as the lead point for the intussusception.
- A right hemicolectomy was performed, and the patient recovered without complications.
- Pathologic diagnosis confirmed the lesion as a lipoma of the large intestine.
Implications:
- This case underscores the importance of considering lipomas as a potential lead point in adult intussusception.
- Highlights the diagnostic utility of CT scans and colonoscopy in evaluating rare causes of bowel obstruction.
- Emphasizes the successful surgical management of intussusception secondary to a large colonic lipoma.

139
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:

01:09Large Intestine
677
The large intestine is divided into three main regions: the cecum, colon, and rectum. Extending from the ileocecal valve to the anus, it frames the small intestine on three sides.
The ileocecal sphincter, a mucous membrane fold, guards the opening from the ileum to the large intestine. This valve permits material from the small intestine to pass into the large intestine. Attached to the ileocecal valve is the cecum. This small pouch, approximately 6 cm long, has a twisted, coiled tube known as...

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...

01:26Histology of the Large Intestine
688
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...

The colon, or large intestine, is the final segment of the digestive system. Its primary functions include absorbing water and vitamins produced by gut bacteria and transforming waste from liquid to solid to form stool. In adults, the large intestine is approximately 5 feet long and consists of four main sections:

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...
