The structures of blood vessels in 18 cases with fundic varices (FV) were studied by injecting gelatin-added barium into varicose vessels of resected specimens. There was no direct connection outside the gastric paries between the inflow path and the outflow path of FV. Just outside the gastric paries, the outflow path was not branched. Blood vessels which formed FV were found in the submucous layer, but not in the lamina propria mucosae. FVs were classified into two types according to the ramification form of FV-forming vessels inside the gastric paries : Type I, with only a few rami observed, and type II, with many rami recognized. In this study, type I FV accounted for about 78%, and type II FV about 22% of 18 cases observed. These findings deserve full consideration in the diagnosis and treatment of FV.

Pancreatic intralobular fibrosis in liver cirrhotic patients was studied immunohistochemically using α-smooth muscle actin (αSMA). Similarly micronodular arrangements of acinar cells and hypertrophy of Langerhans' islands in liver cirrhotic patients were studied using proliferating cell nuclear antigen (PCNA). In addition, pancreata in liver cirrhotic patients were studied from apoptotic side. We investigated the histopathologic autopsy findings of 103 patients :15 patients with alcoholic liver cirrhosis, 49 patients with non-alcoholic liver cirrhosis and, as controls, 39 patients without a history of alcohol abuse or liver dysfunction. αSMA positive area ratio and PCNA positive cell ratio in liver cirrhotic patients were higher than in the controls. In contrast, apoptotic cell ratio in liver cirrhotic patients was lower than in the controls. αSMA positive area ratio in patients with pancreatic intralobular fibrosis was higher than in patients without pancreatic intralobular fibrosis. PCNA positive cell ratio in patients with micronodular arrangements of the acinar cells was higher than in patients without micronodular arrangements of the acinar cells. We conclude that pancreata in liver cirrhotic patients are predominant of proliferating changes.

30 patients with main pancreatic duct stones were treated by ESWL. In 18 of 22 patients who had not previously undergone endoscopic pancreatic sphincterotomy (EPST) or endoscopic sphincterotomy (EST), the stone fragments disappeared after ESWL. The fragments were removed endoscopically in the remaining 4 cases. Complete clearance was achieved in 8 cases with endoscopically unextractable stones by ESWL. After the ESWL procedure, absolute relief from pain was reported by in 19 of 22 patients with abdominal complaints. Serum amylase levels decreased significantly, and dilatation of the main pancreatic duct (MPD) was reduced. In the medium-term follow-up period, pancreatic exocrine function and endocrine function had a possibility to be preserved. One case of pancreatic cancer and one case of an intraductal papillary tumor of the pancreas were found, indicating that careful observation is necessary even after complete removal of pancreatic stones. In cases of Santorini duct dominant, multiple stones, or stricture of the MPD, ESWL should be combined with EPST and endoscopic stenting for preventing recurrence of acute pancreatitis and pancreatic stones. In conclusion, ESWL is the first choice of treatment for pancreatolithiasis and useful procedure and the limited complications.
