Successful outcome of retrograde pancreatojejunostomy for chronic pancreatitis and infected pancreatic cysts: A case report

BACKGROUND: Chronic pancreatitis occasionally requires surgical treatment that can be performed with various techniques. Often, this type of surgery presents with postoperative complications. We report a case of a successful retrograde pancreatojejunostomy for chronic pancreatitis and infected pancreatic cysts. CASE SUMMARY: A 62-year-old male with a 10-year history of chronic pancreatitis presented with epigastric pain for one week and a 20 kg weight loss over one year. Computed tomography showed stones in the pancreas (mainly the head), expansion of the main pancreatic duct, and thinning of the pancreatic parenchyma. Magnetic resonance imaging showed infected pancreatic cysts connected to the stomach with a fistula from the splenic hilum to the caudal portion of the liver’s lateral segment. An endoscopic retrograde pancreatography was performed; the guide wires could not pass through the stones in the pancreas and therefore, drainage of the main pancreatic duct was not achieved. Next, a distal pancreatomy and splenectomy were performed; however, the pancreatic juice in the remaining parenchyma was blocked by the stones. Hence, we performed a retrograde pancreatojejunostomy and Roux-en-Y anastomosis. The patient had no postoperative complications and was discharged from the hospital on postoperative day 14. CONCLUSION: A distal pancreatomy, retrograde pancreatojejunostomy, and Roux-en-Y anastomosis could be an effective surgical procedure for intractable chronic pancreatitis.
