Clinical TrialSonographic diagnosis of pneumoperitoneum using the 'enhancement of the peritoneal stripe sign.' A prospective study.
The objective of this study was to validate the Enhanced Peritoneal Stripe Sign (EPSS) in diagnosing pneumoperitoneum in patients presenting with acute abdomen. The EPSS was described as a specific sonographic sign of pneumoperitoneum in an animal model and few patients who had undergone laparoscopy (Muradali et al. in Am J Roentgenol 173(5): 1257-1262, 1999). This is the first large-scale study in patients to detect the efficacy of EPSS. ⋯ The EPSS thus had a sensitivity of 100%, a specificity of 99%, a positive predictive value of 87.5% and a negative predictive value of 100%. The EPSS is a reliable and accurate sonographic sign for the diagnosis of pneumoperitoneum. It should be looked for in all patients presenting with acute abdominal pain.
