“…After an episode of rejection or venous thrombosis, a new baseline RI must be established. As do other authors, 9 , 13 , 15 , 16 we believe that screening sonography is a useful tool for monitoring pancreatic allografts. On the basis of our findings, we suggest that sonographic examinations be performed in the early postoperative period, whenever complications are suspected, and routinely at 6‐month intervals.…”

“…The past has seen debate about the role of the RI in pancreas allografts. 2,3,12 Some authors have found sonography 5,6,11,[13][14][15][16][17][18][19][20][21] and the RI 4,9,10,22 to be of value, and others have questioned the utility of the RI in the evaluation of pancreatic allografts. 3,5,12 We have found the RI to be clinically useful.…”

We developed a protocol that allowed us to successfully evaluate 96% of the pancreatic allografts studied. Furthermore, our data show that the RI can be used as a therapeutic guide. When the RI is less than 0.65, the risk of vascular abnormalities is very low; however, fluid collections may be present. When greater than 0.75, splenic vein thrombosis, pancreatitis, or rejection should be suspected. When greater than 0.9, rejection must be seriously considered.

Ultrasound of the pancreas: update and controversies

The pancreas is an organ that often presents difficulties for ultrasound exploration due to the interference of abdominal gas in the stomach and duodenum. However, with technical experience and the use of a variety of examination techniques, such as filling the stomach with water or cellulose suspension, changing patient's position, or scanning at different moments of respiration, such as suspended inspiration or expiration, it can be seen in its totality in a high percentage of patients. In our opinion, especially as new technical advances have been incorporated into US equipment (color power Doppler, harmonics, and US pulse inversion) and new contrast agents are available, US can compete with CT in this field. Ultrasound can be as useful as CT in most patients with pancreatitis and pancreatic neoplasms. Furthermore, Endoscopic sonography (ES), as well as intraoperative and laparoscopic techniques, are also excellent for visualizing malignant pancreatic lesions and have a special role in preoperative staging. Finally, US is a good technique to guide fine-needle biopsy of the pancreas and for aspiration of inflammatory fluid collections and abscesses. Although CT has played a major role to date, US is presently the most widely available and economical means to visualize the pancreas.

“…This finding is contrary to several published studies that demonstrated that heterogeneity along with an increase in transplant size were associated with acute rejection. 17,18,22,25 These differing results, however, may reflect differences in the severity of rejection.…”

Editor's Note: This paper won second place in the original research category of the W. Frederick Sample Student Excellence Award Competition. Multiple allograft duplex sonographic examinations were performed on six patients who underwent pancreas transplantation to determine the role of this imaging modality. Poor correlation was found between gland size, parenchymal echogenicity or resistive index, and either rejection and/or cyclosporine toxicity. The pancreatic duct was not dilated on any of the examinations. Seven peripancreatic fluid collections were noted but were generally small. In one patient, no Doppler frequency shifts were found in spite of extensive interrogation of the parenchyma and subsequent biopsy confirmed allograft infarction. Duplex sonography appears most useful for excluding ductal dilatation, for detecting peripancreatic fluid collections, and for identifying infarction.Pancreas transplantation is a recently advocated surgical method of treating selected patients with Type 1 insulin-dependent diabetes mellitus. Although this procedure has been performed since 1966, recent advances in patient selection, surgical technique, and immunosuppression therapy have From the
