摘要
目的我们的研究旨在评估术后下肢肌力（MS），以预测晚期手术成功率（36 个月）：方法：在Roux-en-y胃旁路术（RYGB）前（T0：123人）、术后6个月（T1：123人）和术后36个月（T2：79人）分别进行身体成分分析和等动量测力评估。手术成功率（SS）定义为术后 36 个月超重率（EWL）≥ 50%，或手术失败率（SF）≤ 50%：结果：T1和T2的MS相对伸展（Ext）和屈曲（Flex）没有差异。SS和SF患者在T1和T2的相对MS伸展和屈曲也没有差异。只有在T2，SS和SF患者的相对MS伸展（144.9 ± 39.8牛米/千克 x 125.5 ± 29.2牛米/千克；P=0.04）和屈曲（73.6 ± 21.8牛米/千克 x 60.4 ± 15.8牛米/千克；P=0.02）存在差异。在T1时，Ext和Flex MS增量≥4 Nm/kg的患者在36个月时约有76%是SS患者：结论：RYGB 6 个月后下肢 MS 增量≥4 Nm/kg 可预测 36 个月后的 SS：NCT04129801。
Muscle Strength of Lower Limbs as a Postoperative Predictor in Bariatric Surgery.
Objective: The aim of our study was to assess postoperative lower limbs muscle strength (MS) as a predictor of late surgical success (36 months).
Methods: Body composition analyses and isokinetic dynamometry evaluation were performed before (T0: n=123), six months (T1: n=123) and 36 months (T2: n=79) after Roux-en-y gastric bypass (RYGB). Surgical success (SS) was defined as ≥ 50% excess weight loss (EWL) 36 months after surgery or ≤ 50% surgical failure (SF).
Results: There was no difference between relative MS extension (Ext) and flexion (Flex) in T1 and T2. There was also, no difference between relative MS Ext and Flex in T1 and T2 between patients with SS and SF. There was a difference in relative MS Ext (144.9 ± 39.8 Nm/kg x 125.5 ± 29.2 Nm/kg; p=0.04) and Flex (73.6 ± 21.8 Nm/kg x 60.4 ± 15.8 Nm/kg; p=0.02) between SS and SF patients only in T2. Patients with an increment in Ext and Flex MS ≥4 Nm/kg at T1 had approximately 76% of SS at 36 months.
Conclusion: An increase of lower limbs MS ≥4 Nm/kg 6 months after RYGB predicts SS at 36 months.
期刊介绍：
The Journal of Musculoskeletal and Neuronal Interactions (JMNI) is an academic journal dealing with the pathophysiology and treatment of musculoskeletal disorders. It is published quarterly (months of issue March, June, September, December). Its purpose is to publish original, peer-reviewed papers of research and clinical experience in all areas of the musculoskeletal system and its interactions with the nervous system, especially metabolic bone diseases, with particular emphasis on osteoporosis. Additionally, JMNI publishes the Abstracts from the biannual meetings of the International Society of Musculoskeletal and Neuronal Interactions, and hosts Abstracts of other meetings on topics related to the aims and scope of JMNI.
