“…In this study, the mean PV increased with age, and then started to decline after 50 years, which is consistent with the results of previous studies. [ 3 , 5 , 6 ] However, the mean PV of the individuals aged 60 years was larger than that of the individuals aged 50 years in the male group, possibly because PV was also associated with BMI. An interesting finding that PV seemed to have a significant correlation with age only in females but not males.…”

“…Recently, a Korean study showed that the mean PV values for 1003 individuals, 474 females, and 529 males were 62.648 ± 19.094 cm 3 , 55.762 ± 16.064 cm 3 , and 68.818 ± 19.494 cm 3 , respectively. [ 3 ] The inconsistency in the PV values may be due to differences in patient number, mean age, sex, BMI, and region. Another important reason is that in CT image reconstruction, the use of thinner images may result in more accurate measurements of PV.…”

“…However, in a recent Korean study, it was found that the mean PV was 62.648 cm 3 and that there was a negative correlation between PV and age. [ 3 ] In addition, ethnicity may be related to PV. [ 2 – 4 ] To our knowledge, the normal range of PV values in Chinese adults has not been reported in the English literature.…”

“…[1][2][3] In addition, PV can be used to not only assess disease progression but also determine long-term prognoses. [3] The quantification of changes in PV can lead to new insights in pancreatic diseases diagnosis and treatment. Accordingly, it is important to know the normal range of PV values to identify pathological conditions.…”

To determine the normal range of pancreatic volume (PV) in Chinese adults using computed tomography (CT) volumetry. To assess the relationships of PV with patient demographics and clinical parameters. To analyze the degree of correlation between PV values determined by manual segmentation and those calculated by formulas. A total of 240 adults (120 women, 120 men) between the ages of 18 and 79 years were reviewed. There were 6 groups of patients, with 40 patients in each decade regarding age. PV was segmented manually on computed tomography images slice by slice for each patient, and 2 formulas were used to calculate PV ∗ and PV # . The mean PV was 77.44 ± 19.11 cm 3 (range from 28.55–138.15 cm 3 ). PV was significantly correlated with height ( r = 0.427, P < .001), weight ( r = 0.525, P < .001), body mass index ( r = 0.377, P < .001), the width of the first lumbar vertebral body ( r = 0.166, P = .01), the transverse abdominal diameter ( r = 0.455, P < .001), and the sagittal abdominal diameter ( r = 0.456, P < .001). There was a negative correlation between PV and age ( r = –0.209, P = .001). The correlation coefficients between PV and PV ∗ and PV # were 0.676 and 0.376, respectively, with both P < .001. PV associated with patient demographics and clinical parameters. A more accurate and simpler formula should be used in the future to calculate and monitor changes in PV.

Objectives: Acute pancreatitis is the most critical complication of endoscopic retrograde cholangiopancreatography (ERCP). In this study, we investigated the association between the volume/fat content of the pancreatic head and the incidence of post-ERCP pancreatitis (PEP).Methods: We retrospectively enrolled 157 patients who underwent ERCP. The volume and fat content of the pancreas were calculated by multislice computed tomographic imaging by using a volume analyzer. Multivariate analysis was performed to identify risk factors for PEP. Results:The mean volumes of the whole pancreas and pancreatic head were significantly larger, and the fat content of the pancreatic head was significantly higher in the PEP group (P < 0.01). There were no significant differences in the mean volume and fat content of the pancreatic body and tail in the PEP group. Multivariate analysis revealed that the pancreatic guidewire placement (odds ratio [OR], 12.4; P < 0.01), pancreatic head volume (OR, 5.3; P < 0.01), and the pancreatic head fat content (OR, 4.8; P < 0.01) were independent risk factors for PEP. Conclusions:The pancreatic head volume and fat content were independent predicting factors of PEP. Quantitative assessment of the pancreas may contribute to the prediction of PEP onset.
