Fatty falciform ligament appendage torsion (F-FLAT) is a rare type of intraperitoneal focal fat infarction that involves torsion of a fatty appendage of the falciform ligament. It may cause severe pain, mimicking an acute abdomen, but is typically self-limited and does not require hospitalisation or surgery. As a type of intraperitoneal focal fat infarction, it shares many of the same physiological, clinical and radiological features of epiploic appendagitis. To our knowledge, F-FLAT has not previously been reported in a patient following a laparoscopic Roux-en-Y gastric bypass surgery. Identifying falciform ligament appendagitis is critical because it can prevent unnecessary hospitalisation, follow-up studies and surgery.
