This study is for patients who have had surgery for pancreatic neuroendocrine tumor (pNET). This study is being done to find out if giving chemotherapy after surgery is better or worse than the usual approach for patients that have had surgery for pNET.

Islet transplantation is a clinical procedure to treat patients with chronic pancreatitis after removal of their pancreases. Islet survival is influenced by several factors, including but not limited to triggering an inflammatory response. The loss of islet cells during transplantation can cause surgical diabetes, in which the patient will need insulin injections to regulate their blood sugar. The goal of this study is to test whether co-transplantation of the patient's stem cells, called mesenchymal stromal cells (MSCs), along with their islet cells, will protect transplanted islet cells from death, therefore reducing the patient's chances of getting surgical diabetes. MSCs can modulate immune cells and are a promising resource for cell-based therapy.

This study is for patients with pancreatic cancer. The purpose is to see if researchers can increase the chance of pancreatic cancer staying away by giving them chemotherapy before and after surger

The purpose of this study is to determine if a procedure called Endoscopic Retrograde CholangioPancreatography (ERCP) with sphincterotomy reduces the risk of pancreatitis or the number of recurrent pancreatitis episodes in patients with pancreas divisum. ERCP with sphincterotomy is a procedure where doctors used a combination of x-rays and an endoscope (a long flexible lighted tube) to find the opening of the duct where fluid drains out of the pancreas. People who have been diagnosed with pancreas divisum, have had at least two episodes of pancreatitis, and are candidates for the ERCP with sphincterotomy procedure may be eligible to participate. Participants will be will be randomly assigned to either have the ERCP with sphincterotomy procedure, or to have a "sham" procedure, meaning that you will be treated as if you are having the ERCP with sphincterotomy procedure but the procedure will not really be performed. Participants will have follow up visits 30 days after the procedure, 6 months after the procedure, and continuing every 6 months until the study ends.
