Descending colon ulcers are sores or open wounds that develop on the descending colon, which is part of the large intestine. These ulcers can cause pain, bleeding, and other digestive issues. Understanding them is crucial for effective treatment and prevention.
The descending colon is approximately 25 cm long and extends from the splenic flexure down to the pelvic brim. From the lateral border of the left kidney, it descends vertically and slightly toward the midline in the groove between the psoas and the quadratus lumborum to the iliac crest. It then turns medially in front of the iliacus and psoas major to end in the sigmoid colon. It is covered by peritoneum over its anterior surface and sides, and, like the ascending colon, it may have a narrow mesocolon. However, in most cases, it is fixed on the posterior peritoneum through the Toldt fascia. This is an important surgical plane to allow for a bloodless dissection.
Its posterior surface is related to the lower pole of the left kidney, the origin of the transversus abdominis, the quadratus lumborum, the iliacus and psoas major, the subcostal vessels and nerve, the iliohypogastric and ilioinguinal nerves, the fourth lumbar artery, the lateral femoral cutaneous, the femoral and genitofemoral nerves, the gonadal vessels, and the external iliac artery. On its anterior aspect, it is related to the coils of the small intestine, and in its lower portion, it is related to the anterior abdominal wall. The descending colon is both narrower and more deeply placed than the ascending colon, and tends to be in a more posterolateral position in young women.14
Anatomy of the Descending Colon
The descending colon is a section of the large intestine located on the left side of the abdomen. It connects the transverse colon to the sigmoid colon, which then leads to the rectum. The descending colon plays a key role in absorbing water and salts from food waste before it moves into the rectum for elimination.
Key Features:
- Location: Left side of the abdomen
- Function: Absorption of water and salts, storage of waste
- Connections: Transverse colon → Descending colon → Sigmoid colon → Rectum
Types of Descending Colon Ulcers
Descending colon ulcers can vary based on their causes and characteristics. Here are the main types:
- Ischemic Ulcers: Caused by reduced blood flow to the colon.
- Inflammatory Ulcers: Result from chronic inflammation, such as in Crohn’s disease or ulcerative colitis.
- Infectious Ulcers: Develop due to bacterial, viral, or parasitic infections.
- Medication-Induced Ulcers: Caused by long-term use of nonsteroidal anti-inflammatory drugs (NSAIDs) or other medications.
- Traumatic Ulcers: Result from physical injury to the colon.
