Natural history of pancreatitis-induced splenic vein thrombosis: a systematic review and meta-analysis of its incidence and rate of gastrointestinal bleeding

“…For example, between 1969 and 1984, 45% of patients reported with PISVT initially presented with GI bleeding 7 . Similarly, removing the limit on study age in the literature included in this analysis yields an overall PISVT incidence of 14.1% (22.6% in AP and 12.4% in CP) and a bleed rate of 19.0% 2,3,6,7,9,11–14,17–45 . A comparison of these data with results reported in the current review indicates both an increasing awareness of PISVT and a decreasing concern for GI bleed in the era of universal cross‐sectional imaging.…”

“…After duplicates had been removed and the exclusion criteria noted in Table 2 applied, 47 clinical studies and 52 case reports were graded as relevant; these referred to a cohort of 805 distinct patients with PISVT. Thirty‐eight references were assessed as eligible for quantitative inclusion by the reviewers 2,3,6,7,9,11–14,17–45 . The median CEBM level of included studies was 2A 15 .…”
