Information: - In biology, antrum is a general term for a cavity or chamber, which may have specific meaning in reference to certain organs or sites in the body. - The jejunum is the second part of the small intestine in humans and most higher vertebrates, including mammals, reptiles, and birds. - Halitosis, colloquially called bad breath, or fetor oris, is a symptom in which a noticeably unpleasant odor is present on the exhaled breath. Concern about halitosis is estimated to be the third most frequent reason for people to seek dental care, following tooth decay and gum disease; and about 20% of the general population are reported to suffer from it to some degree. - An odor or odour or fragrance is caused by one or more volatilized chemical compounds, generally at a very low concentration, that humans or other animals perceive by the sense of olfaction. Odors are also commonly called scents, which can refer to both pleasant and unpleasant odors. The terms fragrance and aroma are used primarily by the food and cosmetic industry to describe a pleasant odor, and are sometimes used to refer to perfumes, and to describe floral scent. In contrast, malodor, stench, reek, and stink are used specifically to describe unpleasant odor. The term smell (in its noun form) is used for both pleasant and unpleasant odors. - 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 . - The stomach is a muscular, hollow, dilated part of the gastrointestinal tract that functions as an important organ in the digestive system. The stomach is present in many animals including vertebrates, echinoderms, insects (mid-gut), and molluscs. In humans and many other vertebrates it is involved in the second phase of digestion, following mastication (chewing). - Billroth I, more formally Billroth's operation I, is an operation in which the pylorus is removed and the proximal stomach is anastomosed directly to the duodenum. - Billroth II, more formally Billroth's operation II, is an operation in which the greater curvature of the stomach is connected to the first part of the jejunum in end-to-side anastomosis. This often follows resection of the lower part of the stomach (antrum). The antrectomy (resection of the stomach antrum) is not part of the originally described procedure. The surgical procedure is called gastrojejunostomy. What is the relationship between 'gastrojejunocolic fistula' and 'disease'?
