Endoscopy in dyspeptic patients: is gastric mucosal biopsy useful?

Am J Gastroenterol. 1990 Jun;85(6):701-4.


Should dyspeptic patients coming to endoscopy with "normal" findings also be biopsied? To assess this, we studied the sensitivity and specificity of endoscopic examination compared with histology, microscopic evidence of Helicobacter pylori, CP-TEST, culture, and serum IgG and IgA antibody titers to H. pylori to determine whether endoscopy and antral biopsies really are useful. One hundred seven consecutive dyspeptic patients (mean age 43 yr) were entered. Four antral biopsies were taken routinely for evaluation by histology, microscopy, CP-TEST, and culture. Serum IgG and IgA antibody levels were measured in all patients. Of symptoms, postprandial bloating was statistically more common in H. pylori-positive than in negative patients. Endoscopy had the poorest sensitivity (37.1%) and specificity (53.3%). Patients with normal endoscopic appearances but histologically confirmed gastritis had significantly higher IgG and IgA titers than the patients normal by both endoscopy and histology and without evidence of H. pylori. This study has shown that endoscopy is unhelpful in dyspeptic patients if endoscopic biopsies are not routinely taken.
