AB  - OBJECTIVE: To compare the rates of abdominal surgery during pregnancy among women
      with previous bariatric surgery (women in the case group) and women with
      first-trimester body mass index (BMI) greater than 35 and no previous bariatric
      surgery (women in the control group). METHODS: We conducted a national cohort
      study, merging data from the Swedish Medical Birth Registry and the Swedish
      National Patient Registry, comparing women who had bariatric surgery from 1987 to
      2011 with women in a control group with first-trimester BMI greater than 35 who
      had not had bariatric surgery. Primary outcome variables were diagnosis and
      surgical procedure codes grouped as five outcome categories: 1) intestinal
      obstruction, 2) gallbladder disease, 3) appendicitis, 4) hernia, and 5)
      diagnostic laparoscopy or laparotomy without the presence of a diagnosis or
      surgical code for outcomes in outcome categories 1-4. Odds ratios were computed
      using multivariate linear regression analysis for each separate pregnancy. For
      all pregnancies in a given woman, general estimating equations with robust
      variance estimation were used. Adjustment was made for smoking, year of delivery,
      maternal age, and previous abdominal surgery. RESULTS: During the first pregnancy
      after bariatric surgery, the rate of surgery for intestinal obstruction was 1.5% 
      (39/2,543; 95% confidence interval [CI] 1.1-2.0%) in women in the case group
      compared with 0.02% (4/21,909; 95% CI 0.0-0.04%) among women in the control group
      (adjusted odds ratio [OR] 34.3, 95% CI 11.9-98.7). Similarly, the rate of
      diagnostic laparoscopy or laparotomy was 1.5% (37/2,542; 95% CI 1.0-1.9%) among
      women in the case group compared with 0.1% (18/21,909; 95% CI 0.0-0.1%) among
      women in the control group (adjusted OR 11.3, 95% CI 6.9-18.5). CONCLUSION:
      Bariatric surgery is associated with an increased risk of abdominal surgery
      during pregnancy.
