Barrett's esophagus
What are the folds of the stomach called?
Rugae

Pancreatic cancer
List the two types of Leukemia:
Myelocytic & Lymphocytic
This typically happens from environmental influences such as alcohol abuse, achalasia and/or heavy smoking.
Esophageal Carcinoma
Neurogenic Disorder: Functional obstruction of distal section of esophagus
Achalasia
Caused by obstruction of appendiceal lumen by a fecalish or post inflammatory scarring
Appendicitis
May be a result of chronic cholecystitis and suggests probable cancer.
Porcelain gallbladder
