The most common location for a Meckel's diveiculum is the:

The most common location of a Meckel's is the terminal ileum usually located 45-90 cm from the ileocecal valve.The location on the antimesenteric border is normal and is not an indication for surgical resection. Also Know:The most common complication from Meckel's diveiculum is bleeding secondary to ulceration of the heterotopic gastric tissue. It is the most commonly encountered diveiculum of the small intestines and represents a true diveiculum. It is the direct result of persistence of the omphalomesenteric duct. Technetium scans can be used to identify diveicula with heterotopic gastric tissue. Acute diveiculitis although not the most common presentation can mimic acute appendicitis clinically. There is much controversy about the treatment of an incidentally found Meckel's diveiculum. The general principles are that it should be removed if there is evidence of heterotopic tissue and/or there is a narrowed neck. Other relative indications include unexplained abdominal symptoms and evidence of prior inflammation. Ref: Tavakkolizadeh A., Whang E.E., Ashley S.W., Zinner M.J. (2010). Chapter 28. Small Intestine.
