Surgical management of isolated caecal varices presenting with massive lower gastrointestinal haemorrhage: a case report and review of the literature.

Caecal varices are extremely rare with poorly defined management due to paucity of data. A 52-year-old man was diagnosed with a 3-day history of melena with a background of chronic liver disease and non-steroidal anti-inflammatory use. Investigations revealed anaemia with haemoglobin of 62 g/L, liver function derangement (Gamma-glutamyl transferase 251 U/L, alanine transaminase 40 U/L, bilirubin 84 umol/L, alkaline phosphatase 85 U/L), coagulopathy (International Normalized Ratio 1.6) and acute kidney injury (Creatinine 285 umol/L). Gastroscopy demonstrated no signs of upper gastrointestinal bleeding or portal hypertension. A large volume haematochezia occurred necessitating resuscitation with massive transfusion protocol, and colonoscopy was abandoned in favour of computerized tomography (CT) angiography, which revealed a large varix feeding the caecum. Urgent laparotomy and a right hemicolectomy was performed with application of abdominal vacuum dressing. The hemicolectomy sample was opened on back table demonstrating large caecal varix causing intraluminal bleeding. The patient was stabilized in intensive care, and a further laparotomy was performed 2 days later where an end ileostomy was formed. Caecal varices have been reported in literature with management via trans-jugular intrahepatic portosystemic shunt, endoscopically or conservatively with beta-blockade. Here we present, to the best of the author's knowledge, the first reported case of successful surgical management of caecal varices.
