Outcome of Enhanced Recovery After Surgery (ERAS) for Colorectal Surgery n Early Elderly and Late Elderly Patients

Introduction: This study aimed to determine the outcome of enhanced recovery after surgery (ERAS) programme in elderly colorectal surgery patients. Materials and Methods: Details and surgical outcomes of elderly patients undergoing elective colectomy and/or proctectomy according to ERAS protocol from 2011 to 2017 were retrospectively reviewed. Patients were divided into 2 groups: early elderly (EE, n = 107) aged 65-74 years old and late elderly (LE, n = 74) aged >= 75 years old. Results: This study included 181 patients. The LE group had poorer baseline characteristics, but the operative details in both groups were comparable. Overall complication and severe complication rates were 28% and 3.3%, respectively. The LE group had a higher overall complication rate (38% vs 22%; P= 0.016) but comparable rate of severe complications (2.7% vs 3.7%; P = 1.00). Median postoperative stay was 4 days (interquartile range [IQR], 4-6 days) and it was not significantly different between both groups (5 days for LE vs 4 days for EE; P = 0.176). No difference was seen in time to gastrointestinal recovery and 30-day mortality or readmission between both groups. Overall compliance with ERAS protocol was 76% (IQR, 65-82%) and it did not vary significantly between the LE (71%) and EE (76%) groups (P = 0.301). However, the LE group had lower compliance with fluid management, nutrition therapy and use of multimodal analgesia. Conclusion: ERAS is a safe and effective protocol that can he used in EE and LE colorectal surgery patients.
