Background
The primary obesity surgery endoluminal (POSE) procedure is an innovative incision-less endoscopic bariatric procedure that is increasingly used. However, variable weight loss response and recurrence post-endoscopic bariatric procedures have at times necessitated laparoscopic bariatric conversion. The safety and approach of conversion to laparoscopic sleeve gastrectomy (LSG) or Roux-en-Y gastric bypass (RYGB), however, have been an active point of discussion within revisional bariatric surgery.
Methods
This retrospective review of four consecutive patients is the largest description of medium-term postoperative outcomes and technical highlights of a laparoscopic conversion of POSE to RYGB. Chart review was completed to evaluate patients’ post-POSE clinical course and perioperative outcomes after surgical conversion.
Results
Early data suggests varied weight loss trajectory with POSE and marked improvement in weight response after surgical conversion. Qualitative review reveals successful single-staged conversions contrary to previous smaller case series describing staged conversions involving endoscopic removal of plications followed by RYGB. Review additionally reveals key perioperative considerations for successful conversions to include intraoperative endoscopy, upper gastrointestinal fluoroscopic studies, and at times computed tomography. The latter study and laparoscopic view of the post-POSE stomach challenge the prior notion that distal POSE allows for easy revision to LSG.
Conclusions
Our case series underscores the complex multifactorial nature of metabolic disease and the increasing importance of a conscientious approach to conversion bariatric surgery as the adoption of POSE and the bariatric patient population continues to grow.
