Navigating the Hump: Managing Moynihan’s Hump During a Laparoscopic Cholecystectomy

Year: 2025

Type: article

Abstract: Moynihan's hump is a rare variant of the right hepatic artery (RHA) characterized by a tortuous RHA coursing near the cystic duct. This complicates cystic artery (CA) identification, increasing the chances of mistaking the RHA for it, resulting in inadvertent injury during a cholecystectomy. We present the case of a Moynihan's hump identified during the critical view of safety assessment in a cholecystectomy performed on a 47-year-old male with cholelithiasis. Our report highlights the surgical challenges, emphasizing the importance of the identification of key structures and techniques to minimize complications. Flexibility in surgical planning and awareness of anatomical variations are crucial for ensuring patient safety.
