Forty-three ultrasound examinations have been done on 17 segmental pancreatic transplants performed for juvenile onset diabetes mellitus. The pelvic transplant was readily studied by both real-time and articulated-arm techniques. Transplants of normal sonographic appearance had normal endocrine function. "he most common finding was peripancreatic fluid ranging from a slight halo above the transplant to tense pancreatic ascites-the result of the functional exocrine pancreas' normal function. Indexing Words: Diabetes mellitus Sonography has become a major tool in evaluation of the pancreas and its pathologic states.' It was, therefore, not surprising when we found ultrasound the most often utilized radiologic investigation of the segmental pancreatic transplant in our institution.2 By March 1981 over 40 human segmental pancreatic transplants had been performed at the University of Minnesota for severe juvenile onset diabetes m e l l i t~s ,~ approximately 25% of the world experience to date.4 This report concerns the sonographic findings in the 23 transplants that have been done between July 1978 and March 1981.
MATERIAL AND METHODSTwenty-three separate human pancreatic allografts have been performed in 20 patients. Clinical data on this group had previously been reported,2 but some points are worthy of repetition here. "he transplants were from both cadaver and living related donors. The transplant consisted of the distal pancreas with the splenic artery and vein, and was placed intraperitoneally . Vascular anastomoses were to the iliac vessels; since the majorFrom the Departments of Radiology,',a and Surgery,z University of Minnesota Hospitals, Minneapolis, Minnesota.
