Effectiveness of Prehabilitation Modalities on Postoperative Outcomes Following Colorectal Cancer Surgery: A Systematic Review of Randomised Controlled Trials

BACKGROUND

Postoperative morbidity in patients undergoing curative colorectal cancer surgery is high. Prehabilitation has been suggested to reduce postoperative morbidity, however its effectiveness is still lacking.

OBJECTIVE

The aim of this study was to investigate the effectiveness of prehabilitation in reducing postoperative morbidity and length of hospital stay in patients undergoing colorectal cancer surgery.

METHODS

A comprehensive electronic search was conducted in the CINAHL, Cochrane Library, Medline, PsychINFO, AMED, and Embase databases from inception to April 2023. Randomised controlled trials testing the effectiveness of prehabilitation, including exercise, nutrition, and/or psychological interventions, compared with usual care in patients undergoing colorectal cancer surgery were included. Two independent review authors extracted relevant information and assessed the risk of bias. Random-effect meta-analyses were used to pool outcomes, and the quality of evidence was assessed using Grading of Recommendations, Assessment, Development, and Evaluations (GRADE) guidelines.

RESULTS

A total of 23 trials were identified (N = 2475 patients), including multimodal (3 trials), exercise (3 trials), nutrition (16 trials), and psychological (1 trial) prehabilitation. There was moderate-quality evidence that preoperative nutrition significantly reduced postoperative infectious complications (relative risk 0.65, 95% confidence interval [CI] 0.45-0.94) and low-quality evidence on reducing the length of hospital stay (mean difference 0.87, 95% CI 0.17-1.58) compared with control. A single trial demonstrated an effect of multimodal prehabilitation on postoperative complication.

CONCLUSION

Nutrition prehabilitation was effective in reducing infectious complications and length of hospital stay. Whether other multimodal, exercise, and psychological prehabilitation modalities improve postoperative outcomes after colorectal cancer surgery is uncertain as the current quality of evidence is low.

Jejum pós-operatório prolongado

Objetivo: analisar o tempo de jejum e tipo de dieta prescrita para reintrodução alimentar no pós-operatório de diferentes especialidades cirúrgicas. Método: estudo quantitativo, retrospectivo, documental e descritivo dos prontuários de pacientes cirúrgicos, com amostra randomizada e estratificada de 464 pacientes, realizado em hospital universitário público de grande porte no Paraná. Realizou-se análise estatística descritiva, apresentando medidas de tendência central e seus intervalos de confiança. Resultados: a média de jejum pós-operatório foi de 9:54h (DP: 6:89), variando de 8 a 30 horas. As clínicas que apresentaram maior tempo de jejum foram cirurgia cardíaca, cirurgia torácica e neurocirurgia, com médias de 18:25h, 14:45h e 12:22h, respectivamente. Quanto à prescrição de dieta no pós-operatório imediato, 51,3% dos pacientes receberam dieta geral, 15,3% dieta leve e 11,9% mantiveram jejum nas primeiras 24 horas após o procedimento cirúrgico. Conclusão: o tempo de jejum encontrado nessa instituição excede as atuais recomendações de protocolos nacionais e internacionais, o que implica aumento de desconfortos para o paciente cirúrgico, como sede, fome e estresse, além da insatisfação com o serviço prestado pela equipe de saúde.
