In simple words: The surgeon makes a connection between a fluid-filled sac (cyst) on the pancreas and the small intestine.This allows the fluid from the cyst to drain into the intestine, reducing pain and the risk of the cyst bursting.

This procedure involves creating a surgical connection (anastomosis) between a pancreatic cyst and the gastrointestinal tract, typically the small intestine, using a Roux-en-Y configuration.The Roux-en-Y technique involves dividing a segment of the small intestine, connecting the distal end to the pancreatic cyst, and then reattaching the proximal end to the distal segment further down, forming a Y-shaped configuration. This creates an internal drainage pathway for the cyst's contents, relieving pain and preventing complications like rupture and bleeding.

Example 1: A 55-year-old female patient presents with a large symptomatic pancreatic pseudocyst causing abdominal pain and discomfort. A Roux-en-Y cystojejunostomy is performed to alleviate symptoms and prevent cyst rupture., A 62-year-old male patient with a history of pancreatitis develops a symptomatic pancreatic cyst.A laparoscopic Roux-en-Y cystojejunostomy is performed to decompress the cyst and relieve symptoms., A 48-year-old female patient with a pancreatic cyst discovered incidentally during imaging undergoes a Roux-en-Y cystojejunostomy to prevent potential future complications.

Preoperative imaging (CT scan, MRI) demonstrating the pancreatic cyst, operative report detailing the procedure and the Roux-en-Y anastomosis technique, postoperative imaging to confirm drainage, and pathology report (if applicable).
