Abstract

Introduction: Recently, accelerometers have received much attention around the world. This study examined whether the preoperative physical activity level measured by an accelerometer could be a useful predictor of post-hepatectomy complications.

Methods: Between December 2016 and December 2020, the physical activity levels of 185 patients were measured using an accelerometer 3 days before hepatectomy and from postoperative day 1 to 7. The patients without postoperative complications (n = 153) and those with postoperative complications (n = 32) were compared using either the χ2 test or Fisher's exact test for nominal variables; continuous variables were analyzed using either Student's t test or Mann-Whitney U test. Differences were considered statistically significant when the p value was <0.05. Risk factors for postoperative complications following hepatectomy were also investigated.

Results: The number of patients with an anatomical resection was significantly higher in patients with postoperative complications (p = 0.001). Furthermore, laparoscopic hepatectomy was performed in 65.4% of patients without postoperative complications and in 25.0% of those with postoperative complications; the difference was statistically significant (p < 0.001). The average preoperative physical activity level was 150.6 kcal/day in patients without postoperative complications and 84.5 kcal/day in those with postoperative complications (p = 0.001). Multivariate analysis identified blood loss, operative time, and preoperative physical activity level as independent risk factors for postoperative complications.

Discussion/conclusion: Patients with lower preoperative physical activity levels are at a high risk of developing postoperative complications after hepatectomy. Hence, preoperative physical activity level measurement may be useful in predicting post-hepatectomy complications.

术前用加速度计测量体力活动水平预测肝切除术后并发症:一项前瞻性观察研究。

近年来，加速度计在世界范围内受到了广泛的关注。本研究考察了术前用加速度计测量的体力活动水平是否可以作为肝切除术后并发症的有用预测指标。方法:在2016年12月至2020年12月期间，185名患者在肝切除术前3天和术后第1天至第7天使用加速度计测量身体活动水平。术后无并发症患者(153例)与术后有并发症患者(32例)采用χ2检验或名义变量的Fisher精确检验进行比较;使用学生t检验或Mann-Whitney U检验分析连续变量。当p值为时，认为差异有统计学意义。结果:在术后并发症患者中，解剖切除的患者数量显著增加(p = 0.001)。无术后并发症的65.4%患者行腹腔镜肝切除术，有术后并发症的25.0%患者行腹腔镜肝切除术;差异有统计学意义(p < 0.001)。无术后并发症患者术前平均体力活动水平为150.6 kcal/天，有术后并发症患者术前平均体力活动水平为84.5 kcal/天(p = 0.001)。多因素分析发现出血量、手术时间和术前体力活动水平是术后并发症的独立危险因素。讨论/结论:术前体力活动水平较低的患者在肝切除术后发生并发症的风险较高。因此，术前体力活动水平测量可能有助于预测肝切除术后的并发症。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
