Reviewer's report:  
 
This case report was written about jejunogastric intussusception after Whipple procedure. This 
manuscript states so me important issues regarding postoperative complications after Whipple 
procedure. However additional discussion would be required to confirm this conclusion. 
Therefore, authors would clarify several matters that mentioned below to confirm these 
conclusion s. 
 
1. Authors reported that jejunogastric intussusception occurred after Whipple procedure. 
As authors say, it might be difficult to clarify the etiology of jejunogastric 
intussusception. However, were there some problems during reconstruction of Whipple 
procedure when looking back at reconstruction retrospectively? Moreover, afferent limb 
seems not to be dilated regardless of jejunogastric intussusception of efferent limb. Could 
authors show the figure for reconstruction of Whipple procedure with Roux -en Y 
reconstruction: at first stage and discuss about reconstruction?  
 
2. Is jejunogastric intussusception associated with the size of anastomosis? In fig.2. 
jejunogastric anastomosis seems to be too wide. Could authors review any literatures 
about the correl ation between the size of anastomosis and jejunogastric intussusception?  
 
3. A case report about complications should be a guide and a lesson for someone who may 
experience the same complication. Unfortunately, some figures to show jejunogastric 
intussusce ption are poor. Could you add any figure of CT to understand jejunogastric 
intussusception well? Additionally, do authors have some pictures of intestinal loop after 
reducing the intussuscepted loop?
