“…Disorders include grass sickness (Howell et al, 1974;Pogson et al, 1992;Cottrell et al, 1999;Milne et al, 2005), volvulus (Crowhurst et al, 1975), impaction (Plummer, 2009), parasitism (Reinemeyer and Nielsen, 2009), idiopathic muscular hypertrophy of the ileum (Chaffin et al, 1992), ileocolonic aganglionosis or lethal white syndrome (Knottenbelt and Pascoe, 1994), Meckel's diverticula (Knottenbelt and Pascoe, 1994), tumors (Taylor et al, 2006), and lipomas (Blikslager et al, 1992), all of which can involve the ileocecal region. To these significant naturally occurring syndromes of equine intestinal dysmotility, which are still poorly understood, the induced condition of postoperative paralytic ileus should also be added because it is a very frequent disorder after laparotomy and intestinal manipulation/resection (Hudson and Merrill, 2008).…”
