The rectum is the last part of the large intestine, just before the anus. The middle rectum refers to the central part of this area. Let’s break down its structure and the systems that support it:
- Structure: The rectum is about 12-15 cm long in adults and is divided into three parts: the upper, middle, and lower rectum. The middle rectum is located between the upper rectum and the anorectal junction (where the rectum meets the anus). It consists of layers of muscles that help push stool out and a mucous lining that absorbs water and salts.
- Blood Supply: The rectum gets its blood supply mainly from the superior rectal artery, a branch of the inferior mesenteric artery. The middle and lower rectum are supplied by the middle rectal artery from the internal iliac artery.
- Nerve Supply: The rectum’s nerve supply comes from both the autonomic nervous system (which controls involuntary actions) and somatic nerves (which control voluntary actions). Key nerves include the pelvic splanchnic nerves and the inferior hypogastric plexus, which help regulate bowel movements.
Types of Middle Rectum Injuries
Injuries to the middle rectum can be classified based on the severity and cause:
- Trauma: Physical injuries from accidents or surgeries.
- Perforation: A tear in the rectal wall, often caused by surgery or injury.
- Inflammatory Injury: Damage caused by inflammation from conditions like inflammatory bowel disease (IBD).
- Infectious Injury: Injuries from infections such as rectal abscess.
- Radiation Injury: Damage from radiation therapy for cancers in nearby organs.
- Chemical Injury: Due to exposure to harsh chemicals or medications.
- Ischemic Injury: Caused by reduced blood supply to the rectum.
- Iatrogenic Injury: Injuries resulting from medical procedures like colonoscopy or surgery.
