Are enhanced recovery protocols after pancreatoduodenectomy still efficient when applied in elderly patients? A systematic review and individual patient data meta-analysis

Abstract

Background

This meta-analysis investigated the effects of enhanced recovery after surgery (ERAS) protocols compared to conventional care on postoperative outcomes in patients aged 70 years or older undergoing pancreatoduodenectomy (PD).

Methods

Five databases were systematically searched. Comparative studies with available individual patient data (IPD) were included. The main outcomes were postoperative morbidity, length of stay, readmission and postoperative functional recovery elements. To assess an age-dependent effect, the group was divided in septuagenarians (70–79 years) and older patients (≥80 years).

Results

IPD were obtained from 15 of 31 eligible studies comprising 1109 patients. The overall complication and major complication rates were comparable in both groups (OR 0.92 [95% CI: 0.65–1.29], p = .596 and OR 1.22 [95% CI: 0.61–2.46], p = .508). Length of hospital stay tended to be shorter in the ERAS group compared to the conventional care group (−0.14 days [95% CI: −0.29 to 0.01], p = .071) while readmission rates were comparable and the total length of stay including days in hospital after readmission tended to be shorter in the ERAS group (−0.28 days [95% CI: −0.62 to 0.05], p = .069). In the subgroups, the length of stay was shorter in octogenarians treated with ERAS (−0.36 days [95% CI: −0.71 to −0.004], p = .048). The readmission rate increased slightly but not significantly while the total length of stay was not longer in the ERAS group.

Conclusion

ERAS in the elderly is safe and its benefits are preserved in the care of even in patients older than 80 years. Standardized care protocol should be encouraged in all pancreatic centers.
