With rising adolescent obesity, the use of adolescent bariatric surgery continues to increase. Although vertical sleeve gastrectomy (VSG) has been shown to be safe and effective, multiple short and long-term complications, including GERD can occur. We present a patient with a history of a laparoscopic VSG who presented with a one-year history of worsening dyspepsia and moderate weight regain (~11kg). UGI revealed concerns for chronic organoaxial gastric volvulus. Intraoperative findings included a dilated proximal pouch, extensive adhesions causing gastric volvulus, and distal gastric sleeve stenosis. After extensive lysis of adhesions, the sleeve was straightened and revised. Additionally, laparoscopically-guided endoscopic balloon dilation was performed addressing the gastric stenosis. Postoperatively the patient’s symptoms resolved. New onset and/or progressive GERD following VSG outside the immediate postoperative period should be evaluated. While conversion to a Roux-en-Y gastric bypass may be required, initial attempts to address gastric adhesions and/or chronic stenosis should be considered.
