BACKGROUND: The @entity6124 ( @entity6124 ) breath test has had positive results in 84% of @entity1 with @entity1744 vs 20% of controls. We hypothesized that @entity6124 would be more prevalent in @entity1 with symptoms consistent with @entity1744 who have undergone previous abdominal surgery. OBJECTIVE: To identify causative factors for @entity6124 . DESIGN: Retrospective review. SETTING: Tertiary colorectal surgery clinic. MAIN OUTCOME MEASURE: Result of @entity6124 breath test. RESULTS: We identified 77 @entity1 whose differential diagnosis included @entity6124 from January 1, 2005, to December 31, 2007; 18 were excluded because of noncompliance with testing and 2 because of a decision to treat @entity6124 without formal testing. Symptoms were chronic @entity490 in 30 @entity1 (53%), bloating in 25 (44%), @entity1142 in 37 (65%), and @entity294 in 7 (12%). Mean (SD) symptom duration was 45 (22) months. Of the 57 @entity1 enrolled in this study, 45 (79%) tested positive for @entity6124 and 37 (82%) of those had a history of surgery, whereas 12 (21%) tested negative for @entity6124 and 9 (75%) of those had a history of surgery. Of the 36 @entity6124 -positive @entity1 with a history of abdominal surgery (mean number of procedures, 2), the surgery locations were as follows: female reproductive organs, 23 (64%); hindgut, 15 (42%); foregut, 8 (22%); and midgut, 6 (17%). Open surgery alone was performed in 32 @entity1 (56%) vs laparoscopic surgery in 7 (12%). Both open and laparoscopic procedures had been performed in 6 @entity1 (11%). Four @entity1 (7%) had a history of small intestinal obstruction. The mean age of @entity6124 -positive @entity1 was higher than that of @entity6124 -negative @entity1 (57 vs 44 years; P < .01). Analysis did not reveal any clinically significant independent factor associated with @entity6124 . CONCLUSION: Physicians should consider @entity6124 in the differential diagnosis of @entity1 with normal anatomic findings and chronic @entity344 .

Small intestinal bacterial overgrowth in XXXX with @entity344 and a history of previous abdominal surgery.
