Gastrojejunocolic fistula

{{Short description|Gastrointestinal disorder in humans}}

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.{{cn|date=May 2022}}
