Laparoscopic vs Open Colorectal Surgery: Weighing Your Options
Colorectal surgery focuses on the treatment of diseases affecting the lower gastrointestinal tract, including the colon, rectum, and anus. These conditions range from benign issues such as haemorrhoids and anal fistulas to more aggressive diseases such as inflammatory bowel disease and colorectal cancer.
Partial vs Total Colectomy: What’s the Difference and What to Expect
A colectomy is a surgical procedure used to remove all or part of the colon when it becomes diseased or damaged. The large intestine—comprising the colon and rectum—is a long, tunnel-like organ located at the end of the digestive system. Its primary role is to absorb water and electrolytes, and to form waste into stool before it exits the body through the rectum and anus.
