[Computed tomographic features of abdominal compartment syndrome complicated by severe acute pancreatitis].

OBJECTIVE

To explore the computed tomographic (CT) imaging features of abdominal compartment syndrome (ACS) complicated by severe acute pancreatitis (SAP) to improve the diagnosis of disease.

METHODS

Thirty-six cases of ACS and 61 cases of non-ACS (NACS) complicated by SAP were studied retrospectively. And the meaningful CT features were studied.

RESULTS

Among them, the ACS vascular complications of abdominal cavity and gastrointestinal bleeding were found significantly more in ACS than in NACS (P < 0.05). The ACS intestinal obstruction occurred significantly more often in ACS than in NACS (P < 0.05). The ACS inferior vena cava pressure, diaphragm elevation, round belly sign and marked seroperitoneum occurred significantly more often in ACS than in NACS (P < 0.05). The score of ACS with Balthazar was higher than that of NACS (P < 0.05). For CT signs associated with ACS, four or more associated with ACS CT characteristics, the diagnostic sensitivity was 96.5%. And the specificity, positive predictive value and negative predictive value were 100%, 100% and 87.5% respectively. And the surgical survival rate was significantly higher than the non-surgical survival (P < 0.05).

CONCLUSION

A comprehensive analysis CT features of ACS is important for early diagnosis and guiding treatment.
