A short esophagus remains an underrecognized yet critical factor in the surgical management of hiatal hernia and gastroesophageal reflux disease. Failure to recognize and adequately treat esophageal shortening may result in tensioned reconstruction, wrap migration, and recurrent herniation. Collis gastroplasty remains the most widely accepted esophageal lengthening procedure when adequate intra-abdominal esophageal length cannot be achieved. We present our initial experience with laparoscopic and robotic-assisted Collis gastroplasty and evaluate its role in the management of true esophageal shortening. A retrospective analysis was performed of 82 consecutive patients who underwent surgical treatment for gastroesophageal reflux disease or hiatal hernia. Seven patients (8.5%) were found to have a true short esophagus and underwent Collis gastroplasty combined with antireflux reconstruction. Surgical approaches included laparoscopic, robotic-assisted, and open procedures. All patients underwent a standardized preoperative evaluation that included upper endoscopy, high-resolution manometry, and contrast imaging studies. Operative time ranged from 120 to 195 minutes, with longer procedures observed in redo and robotic-assisted cases. Estimated blood loss was higher in the robotic-assisted group compared with primary minimally invasive operations. No life-threatening complications occurred. During a follow-up period of 3–30 months, no radiographic recurrence was observed. One patient required prolonged proton pump inhibitor therapy due to residual reflux symptoms. The findings of this study suggest that minimally invasive Collis gastroplasty is a safe and effective adjunctive procedure for patients with true esophageal shortening, restoring adequate intra-abdominal esophageal length and enabling tension-free reconstruction with favorable short-term outcomes. Robotic-assisted surgery may provide technical advantages during complex mediastinal dissection and reconstruction.
