Single-Site Laparoscopic Sleeve Gastrectomy: Preclinical Use of a Novel Multi-Access Port Device

Introduction: Single-site laparoscopy (SSL) has emerged as an alternative technique for sleeve gastrectomy. The author describes the preclinical technique of SSL sleeve gastrectomy through a novel multichannel port device in the porcine model. Methods: Anesthetized swine underwent 3-cm longitudinal supra-umbilical incision. A multichannel port device was inserted. A gastric sleeve was created by multiple applications of a 60-mm stapler. The access device’s channel housing was removed and the sleeve specimen exteriorized. Results: The mean operative time was 60 ± 10 minutes, and the mean estimated blood loss was 30 ± 5 cc. The multichannel port device allowed induction and maintenance of pneumoperitoneum throughout the procedure (range 12-15 mm Hg) with efficient rotation and substantial abdominal wall torque and minimal instrument clashing. Conclusion: SSL sleeve gastrectomy in the porcine model was facilitated by the use of a novel multichannel port device. Clinical studies are warranted.

Key Words: laparoscopy • sleeve gastrectomy • single-site laparoscopy • morbid obesity • multi-access port device
