case_images: Abdominal CT revealed axle-shaped omental vessels, a spiral omentum, and an increased concentration of fat in the twisted omentum (Fig. 1).
case_images: Intraoperative findings of Case 1. (A) A cord-like tissue (white arrow) extending from the twisted greater omentum to the lesser omentum was observed. (B) The adhesion of the twisted omentum to the falciform ligament (yellow arrow) had become detached. (C) The adhesion of the twisted omentum to the inferior liver (red arrow) had become detached. (D) The twisted omentum was mobilized by cutting the cord-like tissue. (E) The twisted omentum (black arrows) was removed from the abdominal cavity via an umbilical incision.

case_images: A CT scan of the abdomen revealed a mass-like lesion on the ventral side of the ascending colon, with localized increased density of the surrounding fat tissue in the greater omentum and spiral-shaped omental blood vessels (Fig. 3).
case_images: Intraoperative findings of Case 2. (A, B) The adhesion of the twisted omentum (black arrow) to the abdominal wall (yellow arrow) had become detached. (C) The adhesion of the twisted omentum to the normal omentum (white arrow) had become detached. (D) The twisted omentum was completely mobilized. (E) The twisted omentum was removed from the abdominal cavity via an umbilical incision.

case_images: The twisted omentum was removed from the abdominal cavity through an umbilical incision, while a partial omentectomy was performed (Fig. 4).
