Intestinal lymphangiectasia in the adult may be characterized as a disorder with dilated intestinal lacteals causing loss of lymph into the lumen of the small intestine and resultant hypoproteinemia, hypogammaglobulinemia, hypoalbuminemia and reduced number of circulating lymphocytes or lymphopenia.
Lymphangiectasia is a pathologic dilation of lymph vessels. When it occurs in the intestines of dogs, and more rarely humans, it causes a disease known as "intestinal lymphangiectasia". This disease is characterized by lymphatic vessel dilation, chronic diarrhea and loss of proteins such as serum albumin and globulin.
Primary intestinal lymphangiectasia is rare disorder of dilated intestinal lacteals resulting in lymph leakage into the small bowel lumen, causing protein losing enteropathy leading to lymphopenia, hypoalbuminemia and hypogammaglobulinemia (Orphanet J Rare Dis 2008;3:5, eMedicine: Intestinal Lymphangiectasia [Accessed 12 February 2018]) Dilation of lymphatics in mucosa, submucosa or subserosa

On biopsy chyle was released indicating dilated lacteals or a lactocele. Pancreatic Cancer that Infiltrates the Duodenal Wall. The cat scan showed a tumor of the head, this nodule is in the second part of the duodenum that was proven to be by biopsies adenocarcinoma.
A lacteal is a lymphatic capillary that absorbs dietary fats in the villi of the small intestine. Triglycerides are emulsified by bile and hydrolyzed by the enzyme lipase, resulting in a mixture of fatty acids, di- and monoglycerides. These then pass from the intestinal lumen into the enterocyte, where they are re-esterified to form triglyceride.
Both times, I had polyps removed ... and both in December 2013 and one just yesterday, I had inflamed polyps removed that were at the gastroesophageal junction. My doctor also reported "dilated lacteals" in the duodenum which he biopsied. I did some quick internet searches on dilated lacteals, but what I found was very technical.
PDF | Although duodenal lymphangiectasia in individuals without clinical evidence of malabsorption has been reported, the prevalence and clinical significance in this situation are not yet known.
