We examined endoscopic findings by POPS (Peroral Pancreatoscopy) for 24 patients suffering from chronic panceratitis, 18 with advanced pancreatitis (ADP) and 6 withmoderate pancreatitis (MOP). Abnorrnal findings of the main pancreatic duct mucosa wereobtained in 220f the 24 cases (91.7%), 4 of 6 MOP cases (66.7%) and all of 18 ADP cases (100%). Of the 4 positive, MOP cases, rough mucosa was demonstrated in 3 (75%), redness in 2 (50%), scar in 2 (50%) and granular mucosa in 1 (25%). The 18 ADP cases werecharacterized by rough mucosa in 13 (72.2%), edematous mucosa in 11 (61.1%), redness in7 (38.9%), scar in 6 (33.3%), granular mucosa in 4 (22.2%) and nodu.lar change in 2 (11.1%). As regards intraductal abnormal findings of the main pancreatic duct, significant floatingsubstances were found in 20f 6 MAP cases (33.3%) and in all of 18 ADP cases (100%). Pancreatolitiasis was also revealed in 10 of 18 ADP cases (55.6%). By POPS, the numbefs of abnorrnalities of the rnain pancreatic duct rnucosa, intraductal floating substances and appearance of pancreatalitiasis in chronic pancreatitis were increased, parallel to pancreatography. From these results, we concluded that POPS is a useful methods for thediagnosis of chronic pancreatitis.
