Post robot-assisted exenteration for locally advanced sigmoid colon cancer treated with neoadjuvant chemotherapy, a pelvic abscess from anastomotic dehiscence was identified.

The Pulley maneuver using barbed sutures has been used for laparoscopic hepatectomy; however, the sutures are single-use and may pass through the liver parenchyma, making it uneconomical and inflexible.

The metal clip prevented the nonabsorbable polymer clip from slipping, allowing one suture to be reused three times. Before liver transection, the suture was passed through the liver surface twice, with the clips to reduce iatrogenic damage. The sutures were anchored to the diaphragm or peritoneum for optimal liver traction. A laparoscopic or robotic grasper adjusted the suture tension for the appropriate transection plane. In open-pit-shaped resections, the liver is lifted ventrally for deeper access, whereas in wedge-shaped resections, it is elevated in the caudal view.
