Descending Colon Intussusception Presenting With Bleeding per Rectum.

Intussusception happens when the proximal bowel invaginates into the distal bowel, which can compromise the blood supply and may cause bowel obstruction. Colon intussusception is rare in adults and accounts for only a small proportion of bowel obstructions. Lower gastrointestinal bleeding is rarely caused by this pathology. Intussusception may be idiopathic or the result of underlying benign or malignant pathology. The diagnosis became more reliable with the liberal use of CT. In most cases, it is recommended to respect the involved bowel segment. The patient presented here is a young, otherwise healthy female patient who presented to our hospital with abdominal pain and fresh bleeding per rectum. The CT scan revealed colon intussusception. Laparoscopic left colon resection was performed, and the pathology revealed a submucosal lipoma as the underlying cause.
