title: Serum sodium levels in sigmoid volvulus.
abstract: OBJECTIVE
  Sigmoid volvulus (SV) is an uncommon type of large bowel obstruction. This study sought to determine serum sodium concentrations in patients with SV.
  
  
  METHODS
  The records of 89 patients with SV and 40 patients with obstructive rectosigmoid cancer (ORC) were reviewed retrospectively.
  
  
  RESULTS
  The mean serum sodium concentrations in patients with SV and in those with ORC were 138.4±4.5 mEq/L and 137.7±3.2 mEq/L, respectively (t:0.7, P>0.05). The numbers of hyponatremic and hypernatremic patients were 13 vs. 4 and 1 vs. 0, respectively, in the SV and ORC groups (x2:0.5, P>0.05).
  
  
  CONCLUSIONS
  No cause-effect relationship was determined between serum sodium concentrations and SV.
