In metabolic bariatric surgery (MBS) a lot of focus is made on preoperative risk assessment to enhance patient's baseline performance and improve postoperative clinical outcomes. The aim of this study is to assess pre-operative sarcopenia by computed tomography (CT) scan, as a predictive tool for early post-operative complications in candidates for MBS.
This is a single center prospective case-control study. The study includes using non-contrast CT cuts at L3 vertebra level to measure total abdominal muscle area (TAMA) and visceral fat area (VFA). TAMA was indexed to the patient height and VFA/TAMAI ratio was estimated. Models for predicting postoperative complications were made for TAMA alone, TAMAI alone, VFA alone and VFA/TAMAI ratio to assess each factor's reliability in predicting postoperative complications.
The study enrolled 30 patients who underwent laparoscopic sleeve gastrectomy (LSG); 14 experience early post-operative complications in the cases arm, matched against 16 in the control arm. TAMA and TAMAI showed a significant association with early post-operative complications.
Our findings suggest that TAMA and TAMAI, measured by non-contrast CT as markers for sarcopenia, may be associated with early post-operative complications for laparoscopic sleeve gastrectomy (LSG) patients.
在代谢性减重手术（MBS）中，很多关注点都在于术前风险评估，以提高患者的基线表现并改善术后临床结果。本研究的目的是通过计算机断层扫描（CT）评估术前肌肉减少症，作为MBS候选患者术后早期并发症的预测工具。
这是一项单中心前瞻性病例对照研究。该研究包括使用L3椎体水平的非增强CT切片来测量总腹部肌肉面积（TAMA）和内脏脂肪面积（VFA）。TAMA根据患者身高进行指数化，并估算VFA/TAMAI比率。分别针对单独的TAMA、单独的TAMAI、单独的VFA以及VFA/TAMAI比率建立预测术后并发症的模型，以评估每个因素在预测术后并发症方面的可靠性。
该研究纳入了30例行腹腔镜袖状胃切除术（LSG）的患者；病例组中有14例出现术后早期并发症，对照组中有16例。TAMA和TAMAI与术后早期并发症存在显著关联。
我们的研究结果表明，通过非增强CT测量的TAMA和TAMAI作为肌肉减少症的标志物，可能与腹腔镜袖状胃切除术（LSG）患者的术后早期并发症有关。
