Summary
Adult intussusception, often caused by malignancy, can present subtly. This case highlights ileocolic intussusception secondary to colonic adenocarcinoma, discovered incidentally due to bradycardia.
Area of Science:
- Gastroenterology
- Oncology
- Cardiology
Background:
- Intussusception involves intestinal invagination, frequently linked to a lead point in adults.
- Malignancy is a critical concern as a lead point for adult intussusception.
Observation:
- A 57-year-old woman presented with nonspecific symptoms including abdominal pain and fatigue.
- Incidental bradycardia (heart rate ~40 bpm) prompted further investigation.
- Computed tomography revealed ileocolic intussusception.
Findings:
- The intussusception was caused by a colonic adenocarcinoma originating near the cecum.
- Pathology confirmed stage II colonic adenocarcinoma involving the appendiceal orifice and ileocecal valve.
- Surgical resection included a right hemicolectomy.
Implications:
- This case underscores the importance of investigating nonspecific symptoms, especially when accompanied by incidental findings like bradycardia.
- Early detection of intussusception secondary to malignancy is crucial for patient outcomes.
- Highlights the varied clinical presentations of gastrointestinal malignancies.

01:25Assessment of the Rectum and Anus
208
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.

01:22Appendicitis-I: Introduction
128
The appendix, a small, narrow, blind tube extending from the inferior part of the cecum, is widely regarded as a vestigial organ, having lost much of its original function through evolution. Despite its diminished role, the appendix can become inflamed, a condition known as appendicitis.
Etiology: Appendicitis can arise from various causes, primarily rooted in the obstruction of the appendix lumen. Factors contributing to this obstruction include fecal accumulation, lymphoid hyperplasia and, in...

01:21Inflammatory Bowel Disease V: Surgical Management
145
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
744
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...

01:23Renewal of Intestinal Stem Cells
2.6K
The intestinal epithelial lining rapidly renews every 4 to 5 days. The renewal is facilitated by intestinal stem cells (ISCs) located at the base of the crypt– a gland located at the bottom of each villus. ISCs divide asymmetrically to form new stem cells and progenitor daughter cells. The daughter cells are called transit-amplifying (TA) cells which move upwards along the crypt and either differentiate into absorptive cells– the enterocytes or secretory cells– including the...
