|April 24, 2023
Summary
Rectal cancer can present unusually, like a perirectal abscess, especially with other symptoms. Early diagnosis and treatment, including surgery and chemoradiation, are crucial for remission.
Area of Science:
- Gastroenterology
- Surgical Oncology
Background:
- Rectal cancer (RC) symptoms like bleeding and pain are often nonspecific and can be misdiagnosed.
- Rare presentations of RC can delay diagnosis and treatment.
Observation:
- A 52-year-old male with diabetes presented with symptoms mimicking a perirectal abscess and sepsis.
- Initial symptoms of rectal bleeding and bowel habit changes were attributed to other causes over two years prior.
Findings:
- Workup revealed rectal adenocarcinoma (pT4N0M0, stage IIB/C) presenting as a perirectal abscess.
- Successful treatment involved debridement, antibiotics, neoadjuvant chemoradiation, and abdominoperineal resection.
Implications:
- Rare presentations of rectal cancer, such as perirectal abscess, require high clinical suspicion.
- Integrating rare presentations with conventional symptoms aids in timely rectal cancer diagnosis and management.

01:25Assessment of the Rectum and Anus
303
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
319
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...

324
Introduction
Inflammatory bowel disease, commonly known as IBD, refers to a collection of disorders that lead to persistent inflammation of the gastrointestinal tract. The two types of IBD are ulcerative colitis, which impacts the colon, and Crohn's disease, which can involve any part of the gastrointestinal segment.
Crohn's disease
Crohn's disease is a chronic, systemic inflammatory bowel disease (IBD) that predominantly affects the gastrointestinal tract. It is marked by...
