Gastric outlet obstruction by polypoid tumors.

Dear Editor,

I have read the article titled, "A rare cause of gastric outlet obstruction," which was recently published in this journal (1) with great interest. I have previously seen a similar case; however, this report particularly interested me (2).

First, I would request the authors to provide more details regarding Figure 2. A part of the endoscope is visible in this picture. Is this a retroflexed view of the endoscope entering the stomach at the esophagogastric junction? Is there also an image of the gastric outlet obstructed by the polypoid tumor?

Second, "combined right and left bile duct variations" are mentioned in this article (below Figure 3); however, no further description is provided.

I would like to thank the authors for presenting this special case, and I would request them to provide the required details at the abovementioned instances.
