Outcomes following pancreaticoduodenectomy for octogenarians: a systematic review and meta-analysis

An increasing number of elderly patients are being diagnosed with pancreatic cancer, with increasing need to consider pancreatic surgery. This study aims to provide an updated systematic review and meta-analysis to evaluate the outcomes following pancreaticoduodenectomy in octogenarians.

A systematic review and meta-analysis was performed via a search of Medline, PubMed and Cochrane databases. Studies comparing outcomes of patients >80 years to younger patients undergoing PD were included.

26 studies were included. This included 22481 patients, with 20134 (89.6%) aged <80 years old, and 2347 (10.4%) octogenarians. Octogenarians were associated with higher rates of mortality (OR 2.37 (95%CI 1.91-2.94, p < 0.00001)), all-cause morbidity (OR 1.60 (95%CI 1.30-1.96), p<0.00001) and re-operation (OR 1.41 (95%CI 1.13-1.75), p = 0.002). Octogenarians had a two-fold risk of cardiac complications and respiratory complications (OR 2.13 (95%CI 1.67-2.73), p < 0.00001), (OR 2.38 (95%CI 1.72-3.27), p < 0.0001). There was no difference in postoperative pancreatic fistula, post-pancreatectomy hemorrhage or delayed gastric emptying. Younger patients were more likely to return to adjuvant therapy (OR 0.20 (95%CI 0.12-0.34), p < 0.00001).

Octogenerians are associated with higher mortality rate, postoperative complications, and reduced likelihood to undergo adjuvant therapy. Careful preoperative assessment and selection of elderly patients for consideration of pancreatic surgery is essential.
