Introduction: Reflux symptoms associated with stenosis after laparoscopic sleeve gastrectomy can occur secondary to anatomical abnormality including mechanical stenosis and axial deviation, commonly occurring mid-sleeve. Treatment options include endoscopic intervention, including dilatation, stenting, myotomy, and surgical revision, with Roux-en-Y gastric bypass (RYGB) being preferred by many. In this case series, we report six patients who have undergone laparoscopic gastrogastrostomy (GG) for gastric stenosis and propose this as a possible surgical alternative for appropriately selected patients with symptomatic angularis stenosis. Patients and Methods: Medical records for six patients who underwent laparoscopic GG for treatment of persistent reflux symptoms due to angularis stenosis were reviewed. All patients were preoperatively investigated with endoscopy and abdominal three-dimensional computed tomography. Hiatal hernia and esophageal dilation were excluded. After further consultation, patients proceeded to laparoscopic GG. Results: Complete resolution of symptoms was reported in three of six patients, with Visick score 1, while the other three reported significantly improved symptoms. Postoperative body mass index remained similar to prerevision baseline. There were no postoperative complications. Conclusion: Revision to RYGB is effective for stenosis and reflux but can be challenging with the potential for long-term nutritional deficiencies and surgical complications. For patients with angularis stenosis, laparoscopic GG is a simpler revisional procedure that has shown adequate initial outcomes with no short or anticipated long-term complications in this case series. Patients with persisting symptoms could undergo subsequent gastric bypass if needed.
