Background: Laparoscopic Sleeve Gastrectomy (LSG) has become a primary procedure for management of morbid obesity. Different approaches have been described to make it simpler and minimize surgical trauma and complications, including endoluminal, NOTES, and single port techniques. This project aims to perform technically the LSG using a unique intragastric Single Port (IGSG) in animal swine model, evidencing an effective and safe procedure, optimizing the conventional technique.
Materials and methods: IGSG was performed in 4 minipigs, using a percutaneous intragastric single port located in the pre-pyloric region. The gastric stapling of the greater curvature started from the pre-pyloric region towards the angle of His by Endo GIA™ system and the specimen was removed through the single port. In the postoperative day 30, the animals were sacrificed and submitted to autopsy.
Results: All procedures were performed without conversion, and all survived 30 days. The mean operative time was 42 min. During the perioperative period no complications were observed during invagination and stapling. No postoperative complications occurred. Post-mortem examination showed no leaks or infectious complications.
Conclusion: IGSG is a feasible procedure that may be a suitable alternative technique of sleeve gastrectomy for the treatment of morbid obesity.
