From: Role of 3D-CT gastric volumetric study in post-sleeve gastrectomy
A 44-year-old obese female (BMI = 55.5) with postoperative gastric pouch volume is 307 cc. Preoperative weight and 1-year postoperative weight were 164 kg and 90 kg, respectively. 1-year weight reduction percentage is 42.5%, and 1-year postoperative BMI is 30.4. Although postoperative gastric volume is high, the patient had successful postoperative weight loss after 1 year but the % of loss from the excess weight after 1 year is 76.2%, i.e., the gastric volume is high and the % reduction in excess body weight is low compared to patients with smaller gastric volume. A, B CT abdomen are showing staples (arrow) and gastric pouch (circle). C 3D CT gastric volumetry showing gastric volume of 307 cc
