Abstract

Although reports on the safety of laparoscopic cholecystectomy (LC) exist, few have included patients aged ≥ 85 years. Hence, our study aimed to evaluate surgical outcomes of LC in patients aged ≥ 85 years. After excluding patients who underwent other types of surgeries, 583 patients who underwent LC between 2015 and 2022 were included. Patients were classified into two groups based on age: < 85 years (control group, n = 551) and ≥ 85 years (super-elderly group, n = 32). Propensity score matching (PSM) was performed based on preoperative clinical parameters, and intraoperative and postoperative outcomes were compared. After PSM, 28 patients were included in each group. Intraoperative blood loss (1 vs. 5 mL, respectively; P = .052) and frequency of serious postoperative complications (Clavien-Dindo class ≥ 2, 2/28 (7.1%) vs. 6/28 (21.4%), P = .252) were similar between the control and elderly groups. There was no significant difference in the length of postoperative stay (control group: 5 (4-24) days vs. super-elderly group: 7 (3-64) days, P = .236). Unfortunately, one case of pneumonia of unknown cause occurred postoperatively, resulting in the death of one patient in the super-elderly group. There were no clinically significant differences in the short-term outcomes of LC between super-elderly patients aged ≥ 85 years and patients aged < 85 years. Hence, LC may be relatively safe even in patients aged ≥ 85 years. However, owing to many pre-existing diseases and deterioration of physiological function, careful management during the perioperative period is desirable.
