  • Title: Digestive endoscopy: relevance of negative findings.
    Author: Lambert R.
    Journal: Ital J Gastroenterol Hepatol; 1999 Nov; 31(8):761-72. PubMed ID: 10730569.
    Abstract:
    In patients with digestive complaints, endoscopy is the gold standard and is often the primary exploration. Positive findings in upper gastrointestinal endoscopy occur in 30 to 40% in relation to a benign or malignant structural disease. Negative findings occur therefore in 60 to 70% of cases: dyspepsia and/or reflux are functional diseases. Colonoscopy aims essentially at screening of colorectal cancer. Digestive cancer is very rare under 50 years, and most cases detected with symptoms are advanced; asymptomatic early and curable cancer is detected in screening. A negative finding at endoscopy is reliable in the hands of an experienced endoscopist controlling the risk of false negative and false positive findings. A reliable negative endoscopy is beneficial for the quality of life when it relieves anxiousness of the patient. It may be cost effective if drugs and consultations are decreased. Overuse of negative endoscopy is not so much through large indications, that in repetition of negative procedures. The relevance of negative endoscopy in screening for cancer in the upper and lower digestive tract, is whether is should be repeated. There is tendency to increased intervals in surveillance protocols. In the very near future the first role of endoscopy in the primary diagnosis could be challenged by concurrent techniques. Future progress is based upon a Quality Assurance program for quality, experience of the operator a control of the cost and a research programme on tolerance with a trend to reduced sedation.
