Laparoscopic sleeve gastrectomy (LSG) is a relatively new surgical technique for the treatment of morbid obesity. It is unclear whether the volume of the gastric remnant can expand after surgery as a result of intraluminal pressure maintained over time. If this were the case, the increased volume could affect weight loss and the improvement in comorbidities. This study aims to assess the evolution of residual gastric volume (RGV) during the first year after LSG and its relationship with weight loss.
We conducted a prospective study of 112 patients who underwent LSG from February 2009 to December 2013. In order to measure the RGV after surgery, all patients were evaluated radiologically by an esophagogastroduodenal (EGD) transit at 1 and 12 postoperative months.
All patients showed a significant reduction in BMI compared with the preoperative measurement (33.48 ± 5.78 vs. 50.54 ± 6.69 kg/m; p < 0.001). Increased RGV was observed when comparing the results obtained by EGD transit at 1 (68.39 ± 25.89 cm) and 12 postoperative months (122.58 ± 38.76 cm; p < 0.001). There was no association between increase in gastric volume and weight loss at 1-year follow-up (r = 0.01; p = 0.910).
The volume of the gastric remnant increased significantly during the first year after LSG. However, this increase was not associated with weight loss. Further prospective research with longer follow-up periods is needed to confirm or contrast the present results.
腹腔镜袖状胃切除术（LSG）是一种治疗病态肥胖的相对较新的外科技术。目前尚不清楚术后胃残余量是否会因腔内压力长期维持而扩大。如果是这样，增加的容量可能会影响体重减轻和合并症的改善。本研究旨在评估LSG术后第一年残余胃容积（RGV）的变化及其与体重减轻的关系。
我们对2009年2月至2013年12月接受LSG的112例患者进行了一项前瞻性研究。为了测量术后的RGV，所有患者在术后1个月和12个月通过食管胃十二指肠镜（EGD）检查进行影像学评估。
与术前测量相比，所有患者的BMI均显著降低（33.48±5.78 vs. 50.54±6.69kg/m²；p<0.001）。比较术后1个月（68.39±25.89cm）和12个月（122.58±38.76cm）EGD检查结果时，观察到RGV增加（p<0.001）。在1年随访中，胃容积增加与体重减轻之间无关联（r=0.01；p=0.910）。
LSG术后第一年胃残余量显著增加。然而，这种增加与体重减轻无关。需要进一步进行更长随访期的前瞻性研究来证实或对比目前的结果。
