Meta-Analysis (n=4,210)
Does multimodal prehabilitation improve functional outcomes and reduce postoperative complications in patients undergoing major abdominal surgery?
Multimodal prehabilitation before major abdominal surgery improves preoperative functional capacity and reduces overall postoperative complications, though interventions are highly heterogeneous.

BACKGROUND: For patients undergoing abdominal surgery, multimodal prehabilitation, including nutrition and exercise interventions, aims to optimize their preoperative physical and physiological capacity. This meta-analysis aims to explore the impact of multimodal prehabilitation on surgical and functional outcomes of abdominal surgery. METHODS: Medline, Embase and CENTRAL were searched for articles about multimodal prehabilitation in major abdominal surgery. Primary outcomes were postoperative complications with a Clavien-Dindo score ≥3, and functional outcomes, measured by the 6-Minute Walking Test (6MWT). Secondary outcome measures included the quality-of-life measures. Pooled risk ratio (RR) and 95% confidence interval (CI) were estimated, with DerSimonian and Laird random effects used to account for heterogeneity. RESULTS: Twenty-five studies were included, analysing 4,210 patients across 13 trials and 12 observational studies. Patients undergoing prehabilitation had significantly fewer overall complications (RR = 0.879, 95% CI 0.781-0.989, p = 0.034). There were no significant differences in the rates of wound infection, anastomotic leak and duration of hospitalization. The 6MWT improved preoperatively in patients undergoing prehabilitation (SMD = 33.174, 95% CI 12.674-53.673, p = 0.005), but there were no significant differences in the 6MWT at 4 weeks (SMD = 30.342, 95% CI - 2.707-63.391, p = 0.066) and 8 weeks (SMD = 24.563, 95% CI - 6.77-55.900, p = 0.104) postoperatively. CONCLUSIONS: As preoperative patient optimization shifts towards an interdisciplinary approach, evidence from this meta-analysis shows that multimodal prehabilitation improves the preoperative functional capacity and reduces postoperative complication rates, suggesting its potential in effectively optimizing the abdominal surgery patient. However, there is a large degree of heterogenicity between the prehabilitation interventions between included articles; hence results should be interpreted with caution.
Jain et al. (Sun,) realizaron un metaanálisis en cirugía abdominal mayor (n=4,210). Se evaluó la prehabilitación multimodal en las complicaciones postoperatorias generales (RR 0.879, IC 95% 0.781-0.989, p=0.034). La prehabilitación multimodal antes de la cirugía abdominal mayor redujo significativamente las complicaciones postoperatorias generales (RR 0.879; IC 95% 0.781-0.989; p=0.034) y mejoró la 6MWT preoperatoria.
