Marking and identifying colon lesions. Tattoos, clips, and radiology in imaging the colon.

Precise knowledge of a lesion's location in the colon is infrequently required. Occasionally, however, this information can be of critical clinical importance. A variety of endoscopic and radiologic techniques have been described to localize an area or site within the colon. Tissue staining or tattooing is the most reliable endoscopic method of colon lesion localization, and India ink provides a long-lasting and probably permanent tattoo of the site. Endoscopic clips are less reliable and remain cumbersome to use. Electronic imaging is an intriguing approach but remains experimental. Sites and lesions also can be identified by barium radiography or fluoroscopy, but these techniques involve added expenses and are not as reliable as tattooing with India ink.

Management of symptoms of gastroesophageal reflux disease: does endoscopy influence medical management?

OBJECTIVES: The purpose of this study was to examine the theories that underlie the clinical decision to perform endoscopy in patients with symptoms of gastroesophageal reflux disease (GERD). Physicians reported that they use endoscopic findings to modify medical treatment of GERD. This study was undertaken to test this hypothesis in clinical practice. METHODS: A consortium of community specialists in gastrointestinal disease was formed. Physicians completed a database on patients undergoing elective endoscopy for symptoms of GERD, which includes symptom severity, endoscopic findings, and medical treatment before and after endoscopy. An increase in medical treatment was defined as an increase in acid suppression therapy, and/or the addition of a promotility drug, and/or referral for surgery. RESULTS: Data were collected prospectively over 6 months on 664 patients with symptoms of GERD, and complete data were available on 598 patients. Barrett's esophagus or active esophagitis (erythema, erosions, or ulceration) was present in 374 patients. Of these patients, 74% had an increase in therapy after endoscopy; for only 5% did therapy decrease. In contrast, among 224 patients with a normal-appearing esophagus, 35% had an increase in treatment and 65% had either a decrease in treatment or no change. In most cases, the increase in treatment was due to persistence of symptoms or because of endoscopic findings in the stomach or duodenum. The differences in treatment changes between the two groups was highly significant (p < 0.0001). CONCLUSION: The results support the theory that physicians often use endoscopic results to tailor medical therapy in patients with symptoms of GERD.

Gastric malignancy.

Gastric cancer remains a clinically important tumor. Changing demographics, the association with Helicobacter pylori infection, and the fact that gastric carcinoma remains the world's second most common malignancy all have rekindled interest in this tumor, resulting in numerous studies attempting to define patterns, associations, and causes. This article focuses on new data regarding this malignancy, especially as it impacts on the endoscopic approach to diagnosis and therapy.
