The pancreas is a vital organ responsible for producing enzymes that aid in digestion and hormones that regulate blood sugar levels. Conditions that may require pancreas surgery include:

1. Pancreatic Cancer: Surgery may be done to remove tumors in the pancreas. Depending on the location and size of the tumor, different surgical techniques may be used. These include the Whipple procedure (pancreaticoduodenectomy), distal pancreatectomy, and total pancreatectomy.

2. Pancreatitis: In cases of severe chronic pancreatitis or acute pancreatitis with complications, surgery might be needed to alleviate pain, remove damaged tissue, or manage complications like pseudocysts or abscesses.

3. Cystic Lesions: Large or symptomatic cystic lesions in the pancreas might require surgical removal, especially if there’s a concern about malignancy.

4. Neuroendocrine Tumors: These are less common tumors that can develop in the pancreas. Surgical options depend on the size and type of the tumor.

5. Pancreatic Trauma: In cases of severe trauma to the pancreas, surgery may be required to repair damage and control bleeding.

6. Chronic Pancreatitis: Surgery might be considered for cases of chronic pancreatitis that don’t respond to other treatments. Procedures like the Frey procedure or the Puestow procedure can be performed to alleviate pain and improve drainage of the pancreatic duct.

7. Pancreatic Divisum: This is a congenital condition where the ducts in the pancreas don’t form properly. Surgical intervention might be needed to improve drainage.

8. Pancreatic Duct Stones: In cases where stones are causing blockages in the pancreatic duct, surgery might be considered to remove the stones and improve pancreatic function.

9. Pancreatic Fistula: After some pancreatic surgeries, leakage of pancreatic fluids can occur. Additional surgery might be needed to correct this complication.
