Pancreatic volume change using three dimensional-computed tomography volumetry and its relationships with diabetes on long-term follow-up in autoimmune pancreatitis

Figure 6 Cumulative re-enlargement rates during follow-up in patients with type-1 autoimmune pancreatitis. A: Overall cumulative re-enlargement rates for all 33 patients at 1, 3, 5, 7 and 10 years of follow-up were 61%, 12.2%, 29.2%, 47.5% and 55.0%, respectively. The overall cumulative re-enlargement rates reached a plateau at 55% after 93 months (7.8 years); B: Cumulative re-enlargement rates were 133%, 13.3%, 29.4%, 52.3% and 64.7% in patients with diffuse-type (D-type) and 0%, 5.6%, 29.0%, 40.8% and 40.8% in patients with mass-forming type (M-type) autoimmune pancreatitis (AIP), and reached plateaus at 64.7% after 93 months (7.8 years) and at 40.8% after 77 months, respectively. Patients with D-type AIP showed lower cumulative re-enlargement rates than patients with M-type AIP, but the difference was not significant (P = 0.56).
