Summary
An 86-year-old male presented with intestinal subocclusion due to colocolonic intussusception caused by a high-grade gastrointestinal stromal tumor (GIST). Early diagnosis and surgical management led to a favorable outcome with adjuvant therapy.
Area of Science:
- Gastroenterology
- Surgical Oncology
- Gastrointestinal Pathology
Background:
- Gastrointestinal stromal tumors (GISTs) are rare mesenchymal neoplasms.
- Colonic GISTs can present with varied symptoms, including obstruction and intussusception.
Observation:
- An 86-year-old male presented with intestinal subocclusion.
- Abdominal CT and colonoscopy revealed colocolonic intussusception with a heterogeneous mass.
- Pathology confirmed a high-grade GIST (pT4 N0) within the intussuscepted segment.
Findings:
- Laparoscopic left hemicolectomy with lymphadenectomy achieved free margins.
- The resected specimen showed a 12x7x6 cm ulcerated polypoid GIST.
- Adjuvant Imatinib therapy was initiated postoperatively.
Implications:
- Colonic intussusception is an uncommon presentation for GIST.
- Multimodality imaging (CT) and endoscopic evaluation are crucial for diagnosis.
- Timely surgical resection and adjuvant therapy are vital for managing high-grade colonic GISTs.

01:09Large Intestine
651
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...

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:

01:25Assessment of the Rectum and Anus
191
Evaluating the rectum and anus plays a crucial role in conducting a thorough physical examination of the gastrointestinal system. Although it may be uncomfortable and often embarrassing for the patient, it holds immense diagnostic value, particularly in detecting gastrointestinal diseases and abnormalities. This guide will explain how to perform this assessment using inspection and palpation methods.

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...

01:23Anatomy of the Intestines
71.7K
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...
