Details of any associated procedures like endoscopic retrograde cholangiopancreaticography (ERCP) or Common bile duct (CBD) stone removal will be recorded. An ERCP will not be done routinely prior to drainage to find out any communication of the cyst with main pancreatic duct (MPD). In patients with recurrence within four weeks an ERCP will be done to rule out ductal communication and a pancreatic stent will be placed if a fistula is found in both surgical and endoscopic groups.
