title: Anemia Outcome After Laparascopic Mini Bypass : Analysis of 107 Consecutive Patients.
abstract: BACKGROUND
  The prevalence of obesity has dramatically increased globally. Weight loss procedures are known to be an effective and reliable method with relatively low complication rate and satisfactory results. Laparoscopic mini-gastric bypass (LMGB) is known as a modified Mason loop procedure with compatible results to laparoscopic Roux-en-Y gastric bypass (LRYGB), and is believed to have even less complication rate. Despite adequate and meticulous supplement therapy, anemia is one of the challenges in patients undergoing LMGB. Thus, we aimed to review the prevalence and severity of anemia in patients undergoing LMGB.
  
  
  METHODS
  A prospectively-maintained database of patients referring to Hazrat Rasoul Akram hospital who underwent LMGB from December 2013 to October 2014 was reviewed retrospectively.
  
  
  RESULTS
  A total of 113 consecutive patients were included in the study. The mean age was 38.7 ± 9.8 years. Mean Body mass index (BMI) was 45.5 ± 6.1 kg/m2 preoperatively and 36.7 ± 5.5 kg/m2 and 33.0 ± 5.3 kg/m2 three and six months after the procedure, respectively. (P = 0.001) Mean excess body weight loss after the procedure was 20% and 53% at three and six months post operatively. Serum hemoglobin (Hb) level decreased significantly in three months (P = 0.036) and remained unchanged in six months compared to 3-month (P = 0.385). Vitamin B12 level increased significantly in three months (P = 0.010) and then decrease in six months to the preoperative level (P = 0.889).
  
  
  CONCLUSIONS
  LMGB is a safe, feasible and an effective alternative weight loss procedure. Simply, anemia can be prevented by utilizing therapeutic dose of multivitamin in patients who underwent this procedure.
