title: Retraction transaminitis: an inevitable but benign complication of laparoscopic fundoplication.
abstract: BACKGROUND
  Transient transaminitis has been identified following laparoscopic abdominal surgery. However, the importance of posture, duration of surgery, and mechanical retraction in its etiology remain unclear.
  
  
  METHODS
  Liver function was assessed preoperatively then at 8, 24, 48 and 72 h following laparoscopic surgery including the following procedures: Nissen fundoplication (LN: n = 10); cholecystectomy (LC: n = 10); inguinal herniorrhaphy (LH: n = 10); and gastrectomy (LG: n = 5).
  
  
  RESULTS
  Aspartate aminotransferase (AST) levels in LN patients exhibited a rapid rise within 8 h, peaking at 48 h before returning toward baseline. In the LN group, AST levels were significantly higher at 8 h and 24 hours compared to all other groups and compared to LG at 48 h and 72 h. At 6-week follow-up all AST levels were normal. No significant differences were seen in other hepatic parameters, and no correlation between AST and duration of operation, gender, or age was identified.
  
  
  CONCLUSIONS
  Antireflux surgery is associated with transaminitis related to hepatic retraction, which is independent of patient posture or duration of observation, and it resolves spontaneously with no clinical consequences.
