Computed tomography characteristics of acute pancreatitis based on different etiologies at different onset times: a retrospective cross-sectional study

Abstract

Background: The clinical characteristics and imaging findings of acute pancreatitis (AP) are different across the various etiologies, the results are conflicting, and their time from symptom onset to imaging varies. The imaging findings of different etiologies at different onset times are unclear. This study aimed to investigate the computed tomography (CT) characteristics of AP based on different etiologies at different onset times. Methods: Patients who underwent plain and contrast-enhanced computed tomography (CECT) for the first attack of AP in 3 hospitals (Affiliated

CT Features of Recurrent Acute Pancreatitis: Early Phase Versus Late Phase

“…Du et al 28 showed that the MCTSI was moderately correlated with the RAC in the early phase of AP and moderately to weakly correlated in the late phase. Bollen et al 33 showed no significant differences between CTSI and MCTSI in assessing the severity of AP.…”

“…27 This may be related to the proportion of NP in RAP (38.29%). Du et al 28 reported that 96.7% of AP patients had positive CT on CECT. Our study also yielded similar results in RAP, indicating that CT could play a major role in RAP assessment.…”

“…13,29,30 The following are the possible reasons for this: (1) as the APACHE II score reflects the systemic inflammatory response syndrome throughout the disease course, the pancreatic injury caused by the first AP episode might have influenced the pancreas to produce a similar inflammatory response 31 ; and (2) the proportion of NP in RAP was as high as 69.46% in the late phase, but the APACHE II score was not reliable for diagnosing NP. 32 Du et al 28 showed that the MCTSI was moderately correlated with the RAC in the early phase of AP and moderately to weakly correlated in the late phase. Bollen et al 33 showed no significant differences between CTSI and MCTSI in assessing the severity of AP.…”

Acute pancreatitis: A review of diagnosis, severity prediction and prognosis assessment from imaging technology, scoring system and artificial intelligence

“…However, the latest relevant clinical research also has encouraging results. A retrospective cross-sectional study enrolled 1924 patients experiencing their first episode of AP from three tertiary referral centers in three different prefecture-level cities of Sichuan Province in China and revealed a positive rate of 96.7% (1860/1924) for CT findings in AP diagnosis based on CECT[ 49 ]. Among these 1860 AP patients with affirmative CT results, MCTSI exhibited positive correlations with both the 2012 RAC and APACHE II, as evidenced by Spearman’s rank correlation coefficients[ 49 ].…”

Possibilities of Transfistula Ultrasound in Predicting Intraoperative Bleeding in Patients with Infected Pancreatic Necrosis

“…Самым коварным является то обстоятельство, что развитие кровотечения возможно на любых этапах периоперационного периода: во время установки дренажей под ультразвуковым контролем, при проведении некрсеквестрэктомии, а также разрыве псевдоаневризмы у пациентов после перенесенного острого панкреатита [17][18][19][20][21]. Если диагностика сосудистых аневризм успешно проводится с помощью компьютерной томографии и такие пациенты стратифицируются в группу высокого риска, то оценка риска развития интраоперационных кровотечений вызывает затруднения [22][23][24][25]. К тому же метод компьютерной томографии имеет определенные ограничения в частоте применения, в частности, из-за лучевой нагрузки [26,27].…”
