Congenital lymphangiectasia and chyloperitoneum in a foal

Suspected idiopathic intestinal lymphangiectasia in two foals with chylous peritoneal effusion

“…In human medicine, a triglyceride concentration higher than 1.24–2.26 mmol/l is considered diagnostic of chylous effusion (Meadows and MacWilliams 1994; Almakdisi et al. 2005; May and Good 2007). In horses, chyloabdomen or chylous peritonitis is rarely recognised and was first described in a foal with an intra‐abdominal abscess in 1983 by Hanselaer and Nyland (1983).…”

“…1994; Campbell‐Beggs et al. 1995; May and Good 2007). In this report, the diagnosis of chylous abdomen was based on the macroscopic appearance and fluid analysis of the peritoneal fluid.…”

“…Lymph leaks from the ruptured lacteals into the abdominal cavity and intestinal lumen, carrying all its contents, such as chylomicrons, lymphocytes and proteins, including albumin and immunoglobulins (Melzer and Sellon 2002). Clinical disease of IL with chylous peritoneal effusion can be observed as abdominal discomfort, protein‐losing enteropathy and electrolyte disturbances (May and Good 2007). In horses, in vivo IL diagnosis has been based on clinical signs, peritoneal fluid analysis, ultrasonographic findings and/or exploratory celiotomy (Hanselaer and Nyland 1983; Mair and Lucke 1992; Edwards et al.…”

“…1994; Campbell‐Beggs et al. 1995; May and Good 2007). Treatment involves conservative or surgical correction of the primary problem, metabolic and dietary support (Melzer and Sellon 2002).…”

Intestinal lymphangiectasia and chyloperitoneum

“…In another report (May and Good 2007), a Quarter Horse foal developed abdominal pain at 7 h of age. A large amount of peritoneal fluid was ultrasonographically evident.…”
