"Liver-loop": a case report of an alternative modified liver hanging maneuver.

The liver hanging maneuver (LHM), introduced by Belghiti et al. in 2001, has been widely adapted to various hepatectomy techniques to reduce blood loss and facilitate parenchymal transection. However, its primary limitation is the risk of vascular injury, particularly near the inferior vena cava (IVC). In this report, we describe a modified "Loop-Hanging" maneuver designed as an alternative to enhance exposure during parenchymal transection and improve the control of Glissonean pedicles. In this case, we employed the technique during an open right hemihepatectomy on a 47-year-old male patient with a complex bile duct injury following two unsuccessful Roux-en-Y hepaticojejunostomies (RYHJ). The patient was referred to our institution due to an RYHJ stricture. Imaging identified a right hepatic artery pseudoaneurysm and a fistula to the biliary limb. After two failed attempts at endovascular embolization, a surgical approach was determined through multidisciplinary discussions. During the surgery, the liver was looped with a nasogastric tube positioned anterior to the IVC, allowing gentle upward traction that facilitated the transection, minimized bleeding, and enhanced pedicle control. The LHM is known to reduce blood loss but carries risks for patients with anatomical variations, scarring, or cirrhosis. Our "Loop-Hanging" technique retains the core advantages of LHM, simplifies the process, and diminishes the risk of vascular injury. Further research is required to assess its safety and broader applicability.
