Nonoperative management is a viable option in most emergency patients presenting with AD and EDA, even in the presence of symptoms of peritonitis or altered laboratory tests. Delayed laparoscopic sigmoidectomy may be useless in certain cases and its results poorer than expected.

The RVFAC is a good index to estimate RVEF in PH patients; even better than the TAPSE in patients with more severe hemodynamic profile, possibly for including the transversal component of right ventricular function in its measurement. Furthermore, RVFAC performance was similar in the two PH groups (PAH and CTEPH).
