Case Report

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 pancreato- duodenectomy 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.

Table 1:


Rendezvous pre-cut method; 12 cases (Figure 1)

Case 1 56-year old male: The guidewire, inserted through the major papilla, came out into the duodenum via the minor papilla. Along this guidewire, the minor papilla was cut by a needle type papillotome (KD-200Q-0721 Olympus) and the catheter was inserted into the minor papilla, then EPS was placed. This is our original procedure, a variant of the rendezvous method [1].

Reverse balloon method; 3 cases (Figure 2,3)

Case 2 13-year old female: She entered into our hospital complaining of reccurent epigastralgia. The guidewire, inserted into the major papilla, came out via Wirsung’s duct, connecting branch, Santorini’s duct and minor papilla into the duodenum. The minor papilla was cut by needle type papillotome (rendezvous pre-cut method), and a balloon catheter was inserted along the guidewire and the minor papilla was dilated from the reverses direction by a 4mm dilation balloon, then EPS could be placed into the dorsal duct [1].

20 cases were diagnosed by ERP and 7 by MRCP. Symptomatic patients had a history of alchohol intake, while asymptomatic patients had no history. 17 calcified cases were all male, alcoholic and symptomatic. 2 symptomatic female cases consisted of 1 IPMN with the minor papilla located in the duodenal diverticulum, and 1 strange shaped IPD (Table 1). After therapy, 21 symptomatic cases became pain free, however calcified cases required treatments many times by pain relapsing. There were no cases of cancer occurrence or death after treatment (Table 2).

Radhika reported 1 case of IPD treated by reverse sphincterotomy of the minor papilla. They used sphincterome to cut the minor papilla [2].

In chronic pancreatitis of which the origin is unknown, many will be diagnosed as IPD by MRCP. Endoscopic treatment via the minor papilla is useful for their treatment. Alcohol intake is probably one reason for their symptom onset.

Table 2:


Figure 1: Rendezvous precut method: guidewire came back into the duodenum and pre-cutting of the minor was done then catheter was inserted into Santorini-duct.


Figure 2: Rendezvous precut method: guidewire came back into the duodenum and pre-cutting of the minor was done then catheter was inserted into Santorini-duct.
