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.
