Letter to Editor/LED Reply

Dear Editor,

We had sincerely read the letter from the reviewers. We appreciated the substantial review on our article and in the meantime, we were so honored and so grateful to submit a satisfying reply as far as we could.

To Answer the Question in the Title

Alimentary limb (AL) was defined as the bowel segment from the gastrojejunal anastomosis to the jejunojejunal anastomosis [1, 2]. Some studies [3, 4, 5] performed this segment at the length of 40–100 cm, which was defined as “short” in our meta-analysis. Some [3, 4, 5, 6, 7] measured 130–150 cm of the segment, which was regarded as “standard.” Some [6, 7] used alimentary limb length at 170–250 cm, regarded as “long.”

Although the bowel segment was clearly defined, unfortunately, the detailed technique of the measurement was not distinctly described in most studies. Most studies illustrated the length by use of figures. It was an unescapable fact that a potential heterogeneity existed in the measurement of AL among these studies...



Rou-en-Y gastric bypass



Thanks so much again for the great interest and substantial review of our meta-analysis. We are very willing to reply more letters to us to discuss any questions in this article. Thanks so much for the opportunity and platform for academic exchanges provided by “Obesity Surgery.”
