Endoscopic Treatments of Pancreatic Incomplete Divisum (PID) in 20 Cases - Especially About Our New Procedures: Rendezvous Pre-Cut Method and Reverse Balloon Method

We have experienced 27 cases of pancreatic incomplete divisum (PID), a type of malformation of the pancreatic duct, in the past 5 years. They consisted of 19 male and 8 female, aged 13-82 y/o. Symptomatic 21 cases were 19 male (calcified 18, non-calcified 1) and 2 female (non-calcified 1, IPMN 1). Asymptomatic cases were 6 (1 non-calcified male,5 female-all were non-users of alcohol. 3 cases were complicated with pseudocysts. Treatment procedures consisted of ESWL+endoscopy (via major papilla) 2, ESWL+endoscopy (via minor)13, endoscopy alone 4 (via minor). 1 case received pancreatoduodenectomy after medical treatment and 1 received pseudocyst resection in the tail without medical treatment. (Table 1) In the literature, reports about PID treatment are few, so we would like to show its treatment method in our hospital, especially 2 new procedures: Rendezvous pre-cut method and reverse balloon method-our new therapeutic procedures.
