title: Anatomical measurements of the gastric cardia in obese patients.
abstract: BACKGROUND
  Currently, surgeons implant a variety of laparoscopic adjustable gastric bands. However, there is little data to guide the selection process. This study aims to determine the relationship between a patient's body mass index (BMI), height, and weight and the anatomical measurements of the gastric cardia in morbidly obese patients undergoing laparoscopic adjustable gastric band (LAGB) surgery.
  
  
  METHODS
  A total of 67 morbidly obese patients undergoing LAGB surgery were studied. Intraoperative measurements of the gastric cardia were obtained. The relative circumference and posterior diameter of the gastric cardia were measured along with the patient's height, weight, and BMI. Pearson's correlation coefficient was used to measure the relationship between the circumference and posterior diameter of the gastric cardia and the BMI, height, and weight. A p < 0.05 was considered significant.
  
  
  RESULTS
  No correlation exists between a patient's BMI or weight and the circumference or diameter of the gastric cardia. A correlation exists between a patient's height and the posterior diameter of the gastric cardia (p = 0.02). Of note, there is a correlation between the relative circumference and the posterior diameter of the gastric cardia for each patient (p = 0.05).
  
  
  CONCLUSIONS
  Our unique data show no significant correlation between a patient's BMI and weight and the measurements of the gastric cardia. There was a correlation between a patient's height and the posterior diameter of the gastric cardia. These intraoperative measurements may help surgeons objectively select the appropriate band for each respective patient undergoing LAGB surgery. This may potentially decrease postoperative dysphagia.
