Assessment of physical fitness for esophageal surgery, and targeting interventions to optimize outcomes.
This review examines how higher levels of physiological reserve and fitness can help the patient endure the demands of esophageal surgery. Lung function, body composition, cardiac function, inflammatory mediators and exercise performance are all determinants of fitness. Physical fitness, both as an independent risk factor and through its effect on other risk factors, has been found to be significantly associated with the risk of developing postoperative pulmonary complications (PPCs) in patients following esophagectomy. Respiratory dysfunction preoperatively poses the dominant risk of developing complications, and PPCs are the most common causes of morbidity and mortality. The incidence of PPCs is between 15 and 40% with an associated 4.5-fold increase in operative mortality leading to approximately 45% of all deaths post-esophagectomy. Cardiac complications are the other principal postoperative complications, and pulmonary and cardiac complications are reported to account for up to 70% of postoperative deaths after esophagectomy. Risk reduction in patients planned for surgery is key in attaining optimal outcomes. The goal of this review was to discuss the risk factors associated with the development of postoperative pulmonary complications and how these may be modified prior to surgery with a specific focus on the pulmonary complications associated with esophageal resection. There are few studies that have examined the effect of modifying physical fitness pre-esophageal surgery. The data to date would indicate a need to develop targeted interventions preoperatively to increase physical function with the aim of decreasing postoperative complications.
