[A Clinical Study of Short-Term Outcomes of High-Difficulty Hepatobiliary Pancreatic Surgery in Elderly Patients Aged 80 and Older at Our Hospital].

We examined 12 cases of high-difficulty hepatobiliary pancreatic surgery performed at our hospital between January 2022 and December 2024 for patients aged 80 and older. The median length of hospital stay after surgery was 33 days. Three cases were discharged due to death, and in all of these cases, the preoperative albumin level was less than 2.5 g/dL. On the other hand, in cases where the preoperative albumin level was 3.5 g/dL or higher, no complications of Clavien- Dindo classification Grade Ⅲ or higher were observed. It has been suggested that the nutritional status before surgery may impact the prognosis after surgery.
