title: Nissen fundoplication for gastroesophageal reflux: No deterioration of gastric emptying measured by C-acetate breath test.
abstract: OBJECTIVE
  To study the gastric emptying 30 days after laparoscopic Nissen fundoplication (NF) in gastroesophageal reflux.
  
  
  METHODS
  Three patients were evaluated with (13)C-acetate breath test (ABT) performed pre and post-NF. The liquid test meal consisted of Racol(™) mixed with (13)C-acetate.
  
  
  RESULTS
  In the patient without neurological impairment (NI), the preoperative t(½)ex and t lag were 0.900 and 0.510 hours, respectively. The postoperative t(½)ex and t lag were 0.959 and 0.586 hours, respectively. In one patient with NI, the preoperative t(½)ex and t lag were 1.828 and 1.092 hours, respectively. The postoperative t(½)ex and t lag were 2.081 and 1.025 hours, respectively. In the other patient with NI, the preoperative t(½)ex and t lag were 2.110 and 0.980 hours, respectively. The postoperative t(½)ex and t lag were 1.118 and 0.415 hours, respectively.
  
  
  CONCLUSIONS
  Our findings suggest that (13)C-ABT parameters did not worsen in any of the children after laparoscopic NF.
