*“Persisting drainage of serous fluid … was treated by keeping the drainage catheter in place until cessation of drainage (range 2–30 d) (Men et al., 1999).

†: Parenchymal liver laceration with active arterial haemorrhage from a branch of the right hepatic artery and the need for endovascular and surgical intervention (Loutfi et al., 2008).

‡: Due to the usage of hypertonic saline as scolecidal agent (Haddad et al., 2000).
