Background/Purpose: Recently, pancreaticoduodenectomies have been performed for choledochal cysts complicated by protein plugs. The authors describe a new surgical procedure for removal of protein plugs or pancreatic stones that does not involve pancreatectomy. Methods: Protein plugs were detected in 43 (34.1%) of 126 pediatric patients with choledochal cysts. The plugs disappeared spontaneously in 26 patients and were removed using nonsurgical methods in seven. The 10 patients treated surgically are considered here. Results: Protein plugs were removed with the residual cyst in one patient. The plugs in the common channel were flushed into the duodenum by irrigation with saline through the narrow segment beneath choledochal cyst in another. The plugs were removed through the narrow segment using a blunt spoon in four. In the other four patients, the plugs that were too large or too hard to be removed through the narrow segment were taken away through an incision in the main pancreatic duct. This was followed by primary closure of the main pancreatic duct using the narrow segment as a flap to prevent stricture formation. All of the patients have done well. Conclusions: Protein plugs complicating choledochal cysts can be removed without pancreatectomy. Particularly, primary repair of the pancreatic duct using a flap made of the narrow segment beneath the choledochal cyst is a safe and feasible method to remove large or hard protein plugs.
