Abstract
The anesthetic management of a patient with an extensive biliary mucinous cystadenoma presents unique challenges that necessitate careful consideration of the patient's physiological status, potential cardiopulmonary and hemodynamic changes resulting from elevated intra-abdominal pressure and possible compression of major abdominal vessels or, as well as the requirement for meticulous fluid and electrolyte management due to fluid and blood loss, and the provision of appropriate analgesic therapy. This case report describes the anesthetic management of a 22-year-old female diagnosed with a sizeable biliary mucinous cystadenoma measuring approximately 32 × 22 × 24 cm. It emphasizes the anesthetic considerations essential to ensure a safe and successful outcome.
