title: Positive Glucose Breath Tests in Patients with Hysterectomy, Gastrectomy, and Cholecystectomy.
abstract: OBJECTIVE
  This study aimed to investigate the prevalence and characteristics of small intestinal bacterial overgrowth (SIBO) in patients undergoing abdominal surgeries, such as gastrectomy, cholecystectomy, and hysterectomy.
  
  
  METHODS
  One hundred seventy-one patients with surgery (50 hysterectomy, 14 gastrectomy, and 107 cholecystectomy), 665 patients with functional gastrointestinal disease (FGID) and 30 healthy controls undergoing a hydrogen (H2)-methane (CH4) glucose breath test (GBT) were reviewed.
  
  
  RESULTS
  GBT positivity (+) was significantly different among the surgical patients (43.9%), FGID patients (31.9%), and controls (13.3%) (p<0.01). With respect to the patients, 65 (38.0%), four (2.3%), and six (3.5%) surgical patients and 150 (22.6%), 30 (4.5%), and 32 (4.8%) FGID patients were in the GBT (H2)+, (CH4)+ and (mixed)+ groups, respectively (p<0.01). The gastrectomy group had a significantly increased preference in GBT+ (71.4% vs 42.0% or 41.1%, respectively) and GBT (H2)+ (64.3% vs 32.0% or 37.4%, respectively) compared with the hysterectomy or cholecystectomy groups (p<0.01). During GBT, the total H2was significantly increased in the gastrectomy group compared with the other groups.
  
  
  CONCLUSIONS
  SIBO producing H2is common in abdominal surgical patients. Different features for GBT+ may be a result of the types of abdominal surgery.
