Rectal stump mucocele after a Hartmann's procedure causing mechanical ileus.

Two years after a Hartmann's procedure, an 85-year-old woman was admitted at our emergency department with abdominal bloating and severe constipation for 5 days. Abdominal CT showed a large rectal stump mucocele associated with compression of surrounding structures, causing a mechanical ileus and a bilateral pyelocaliceal dilatation. Successful transanal drainage with a rectal catheter allowed rapid recovery.
