Background/ObjectivesPatients with a short bowel and receiving parenteral nutrition (PN) have an increased risk of chronic cholestasis (CC). Restoration of bowel continuity after a mesenteric infarction results in PN requirements being reduced or stopped. This study aimed to determine the prevalence of CC and whether restoring bowel continuity reduced the risk of CC.Subjects/MethodsA retrospective review of patients with a short bowel owing to mesenteric infarction from 2000 to 2012. CC was defined as two of bilirubin, alkaline phosphatase and gamma-glutamyl transferase being 1.5 times the upper limit of normal for >6 months.ResultsWe identified 104 (55 females, median age 54 years) patients. Seventy-three (70%) patients had restoration of bowel continuity; of these, 25 (34%) had abnormal liver biochemistry (liver function test (LFT)), with 15 (21%) having CC. Following restoration of bowel continuity, 8 (53%) of 15 patients with CC and 10 (100%) of 10 patients with abnormal LFT but not CC had a return of liver function within normal range within a year. Univariate analysis showed restoring bowel continuity (P=0.002) and cessation of PN (P=0.006) were associated with a reduction in prevalence of CC. Multivariate analysis showed that cessation of PN was a significant factor in reducing CC (P=0.02).ConclusionsThe prevalence of CC is 29% for patients with a short bowel receiving PN following a mesenteric infarction. CC resolves in 53% after continuity is restored, and this is most likely due to stopping or reducing the PN.
