Reduced protocol compliance was the most frequently identified modifiable predictive factor for adverse LOS , morbidity and readmission .
Conclusion Protocol compliance is the most frequently reported predictive factor for outcomes of ERAS programmes following laparoscopic colorectal resection .
Reduced compliance increases LOS , morbidity and readmission to hospital .
The impact of compliance with individual ERAS protocol elements is insufficiently studied , and the lack of a st and ardised framework for evaluating ERAS programmes makes it difficult to draw definite conclusions about which factors exert the greatest impact on outcome after laparoscopic colorectal resection
Objective To perform a systematic review of published literature for the factors reported to predict outcomes of enhanced recovery after surgery ( ERAS ) programmes following  laparoscopic colorectal surgery .
Background ERAS programmes and the use of laparoscopy have been widely adopted in colorectal surgery bringing short-term patient benefit .
However , there is a minority of patients that do not benefit from these strategies and their identification is not well characterised .
The factors that underpin outcomes from ERAS programmes for laparoscopic patients are not understood .
Prehabilitation versus Rehabilitation: A Randomized Control Trial in Patients Undergoing Colorectal Resection for Cancer
Background : The preoperative period ( prehabilitation ) may represent a more appropriate time than the postoperative period to implement an intervention . The impact of prehabilitation on recovery of function al exercise capacity was thus studied in patients undergoing colorectal resection for cancer . Methods : A parallel-arm single-blind superiority r and omized controlled trial was conducted . Seventy-seven patients were r and omized to receive either prehabilitation ( n = 38 ) or rehabilitation ( n = 39 ) . Both groups received a home-based intervention of moderate aerobic and resistance exercises , nutritional counseling with protein supplementation , and relaxation exercises initiated either 4 weeks before surgery ( prehabilitation ) or immediately after surgery ( rehabilitation ) , and continued for 8 weeks after surgery . Patients were managed with an enhanced recovery pathway . Primary outcome was functional exercise capacity measured using the vali date d 6-min walk test . Results : Median duration of prehabilitation was 24.5 days . While awaiting surgery , functional walking capacity increased ( ≥20 m ) in a higher proportion of the prehabilitation group compared with the rehabilitation group ( 53 vs. 15 % , adjusted P = 0.006 ) . Complication rates and duration of hospital stay were similar . The difference between baseline and 8-week 6-min walking test was significantly higher in the prehabilitation compared with the rehabilitation group ( + 23.7 m [ SD , 54.8 ] vs. −21.8 m [ SD , 80.7 ] ; mean difference 45.4 m [ 95 % CI , 13.9 to 77.0 ] ) . A higher proportion of the prehabilitation group were also recovered to or above baseline exercise capacity at 8 weeks compared with the rehabilitation group ( 84 vs. 62 % , adjusted P = 0.049 ) . Conclusion : Meaningful changes in postoperative functional exercise capacity can be achieved with a prehabilitation program
