Abstract:
Chronic pancreatitis (CP) is an inflammatory syndrome that causes irreversible damage and loss of pancreatic function. A late complication is pancreatolithiasis, which exacerbates pain due to intraductal hypertension. In this work, we demonstrate that given the availability of different non-surgical treatment methods, if we are in the presence of dilated ducts, longitudinal pancreaticojejunostomy (Puestow procedure) is the best surgical drainage option. The clinical study is presented through the case of a 56-year-old man with idiopathic CP and recurrent lithiasis. The diagnosis was confirmed by magnetic resonance cholangiopancreatography. A lateral pancreaticojejunostomy was performed according to Puestow with Roux-Y anastomosis for ductal decompression. The intervention resolved ductal hypertension by allowing the drainage of liths. The patient was discharged after 10 days with improvement in liver profile and pancreatic enzymes, remaining asymptomatic during six months of follow-up. The Puestow procedure is a current and highly effective technique for refractory lithiasis CP. It is feasible in patients with stones larger than 2 mm, allowing complete functional recovery and preventing secondary complications.

Chronic Pancreatitis I: Introduction
Pancreatitis is the inflammation of the pancreas, which occurs when the immune system becomes active and causes swelling, pain, and disruptions in organ function. Pancreatitis can manifest as either an acute or chronic condition.
Acute pancreatitis arises suddenly and lasts for a brief duration, while chronic pancreatitis is a long-term affliction...

Acute Pancreatitis I: Introduction
Acute pancreatitis is characterized by rapid inflammation of the pancreas, often caused by factors like gallstone blockage or excessive alcohol consumption. Chronic pancreatitis, on the other hand, is a slow, progressive inflammation that may result from long-term alcohol abuse, obstructions in the pancreatic duct, or genetic factors.
The causes of acute pancreatitis include:
