Clinical Description: Colectomy is a surgical procedure that involves the partial or complete removal of the colon (large intestine) and may be performed to treat conditions such as colorectal cancer, diverticulitis, inflammatory bowel disease, or severe colorectal polyps. The goal is to manage the underlying condition, alleviate symptoms, or reduce the risk of complications. The logic in this definition aims to select for a cohort undergoing non emergent procedures. Further details to aid in the population level evaluation of this cohort will be posted to this thread.
