Introduction. From the time of the acquisition of the Endoscopic Ultrasound system GF-UM130 and the Ultrasonic Probe set MH-247 manufactured by Olympus, the first endoscopic ultrasound in the Philippines, the Institute of Digestive Diseases at St. Lukes Medical Center, Quezon City, Philippines has performed a total of 121 endoscopic ultrasound procedures of various organs from the period of February 1999 to October 2000 Objective. To report the various indications of endoscopic ultrasonography (EUS), to enumerate its findings and if possible correlate it with either surface ultrasonography, CT scan, X-ray, MRI, and biopsy report Methodology. All patients who underwent EUS at St. Lukes Medical Center From February 1999 to October 2000 were included Results. The organs examined were stomach (30 percent), gallbladder (30 percent), colon/rectum (17 percent), esophagus (12 percent), and pancreas (11 percent). The indications for these requests were confirmation of endoscopic findings (30 percent), confirmation of ultrasound findings (24 percent), and others such as epigastric pain, rectal bleeding etc. (16 percent), follow-up study (9 percent), confirmation of CT scan (7 percent), staging (5 percent), surveillance (3.3 percent), confirmation of X-ray findings (2.5 percent), confirmation of MRI findings (1.6 percent). The top 5 findings out of the 121 endoscopic ultrasound examinations are as follows: 22 gallbladder polyps, 10 submucosal tumors of the stomach, 8 gastric cancer, 8 esophageal cancer, and 8 pancreatic head mass. These and the rest of the results were subsequently correlated with US, CT scan, X-ray, MRI, and biopsy. All of the 121 examinations were successful and no complications were noted Conclusion. We conclude that EUS is an accurate, reliable, and safe method in evaluating various gastrointestinal pathology. (Author)
