History and etymology
Alexis Littré (1658-1726) was a French surgeon and Professor of Anatomy in Paris. In the year 1700 he was the first to report three cases of incarcerated femoral hernia containing a small bowel diverticulum. Interestingly he was the first person to suggest colostomy for large bowel obstruction. He also wrote a monograph in 1719 on the male urethra that referenced the glands that now bear his name 4.
