| Abstract |
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(2); p < 0.001). Increased RGV was observed when comparing the results obtained by EGD transit at 1 (68.39 ± 25.89 cm(3)) and 12 postoperative months (122.58 ± 38.76 cm(3); 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. |

Attention Score in Context
This research output has an Altmetric Attention Score of 12. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 23 January 2022.
All research outputs
#2,635,316
of 23,340,595 outputs
Outputs from Obesity Surgery
#284
of 3,447 outputs
Outputs of similar age
#49,769
of 368,876 outputs
Outputs of similar age from Obesity Surgery
#6
of 74 outputs
Altmetric has tracked 23,340,595 research outputs across all sources so far. Compared to these this one has done well and is in the 88th percentile: it's in the top 25% of all research outputs ever tracked by Altmetric.
So far Altmetric has tracked 3,447 research outputs from this source. They typically receive a little more attention than average, with a mean Attention Score of 5.8. This one has done particularly well, scoring higher than 91% of its peers.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 368,876 tracked outputs that were published within six weeks on either side of this one in any source. This one has done well, scoring higher than 86% of its contemporaries.
We're also able to compare this research output to 74 others from the same source and published within six weeks on either side of this one. This one has done particularly well, scoring higher than 93% of its contemporaries.
