3. Figure 2
(A) Baseline normal pancreatogram. A prophylactic 3F 10-cm pancreatic stent was placed. (B) Pancreatogram performed 9 months later for recurrent symptoms showing grade I narrowing in the stented zone (arrow, <20% luminal narrowing).

4. Figure 3
(A) Baseline normal pancreatogram. A prophylactic 4F 8-cm pancreatic stent was placed. (B) Pancreatogram performed 4 months later for persistent symptoms showing grade II narrowing in the stented zone (arrow, 20%–50% luminal narrowing).

5. Figure 4
(A) Baseline normal pancreatogram. A prophylactic 3F 10-cm pancreatic stent was placed. (B) Pancreatogram at stent removal showing grade III narrowing in the stented zone (arrow, >50% luminal narrowing).

6. Figure 5
(A) Baseline normal pancreatogram. A prophylactic 4F 8-cm pancreatic stent was placed. (B) Pancreatogram at stent removal showing grade I narrowing in the stented zone (arrow <20% luminal narrowing). (C) Resolution of the stent-induced changes seen on a pancreatogram performed 8 months later (arrow, no residual narrowing present).
