Gastrojejunocolic fistula

A gastrojejunocolic fistula is a disorder of the human gastrointestinal tract. It may form between the transverse colon and the upper jejunum after a Billroth II surgical procedure. (The Billroth procedure attaches the jejunum to the remainder of the stomach.) Fecal matter thereby passes improperly from the colon to the stomach, and causes halitosis.^{[citation needed]}

Patients may present with diarrhea,^[1] weight loss and halitosis as a result of fecal matter passing through the fistula from the colon into the stomach.
