• Peritoneoscopic observation and biopsy of the pancreas has been reported since 1972. Peritoneoscopy of the pancreas is, however, not routinely performed because of its retroperitoneal positioning and the problems on security. In this report, we examined the security of peritoneoscopic biopsy of the pancreas with biopsy forceps. Animal experiments: No significant increase in serum elastase I levels and amylase activities was observed after rats' partial pancreatectomy and canine pancreatic biopsy using biopsy forceps (Olympus 05106). Clinical investigation : Clinical invastigation on pancreatic biopsy of 45 cases revealed that 1) Supragastric bursoscopy adopted in the present study had restriction in the diagnosis of localized pancreatic disorders in connection with observation area, 2) From the investigation concerning security, the biopsy forceps (Model II) designed by us for obtaining the pancreatic tissue of 3 X 3 mm was thought to be most suitable for pancreatic piopsy, although pancreatitis and transient elevation of serum elastase I level and amylase activity appeared in a case after biopsy using Olympus 05106, 3) No complication such as intraperitoneal bleeding and/or leakage of the pancreatic juice was encountered in careful biopsy using Model II forceps, 4) Development of these forceps (Model I & Model II) was thought to be very useful for the advance of morphological examination of the pancreas.
