Abstract
- Background: In this porcine survival model, we compared laparoscopic computer-mediated flexible circular stapled (SurgASSIST) gastro-jejunostomies in Roux-en-Y gastric bypass (RYGBP) to open hand-sewn (HS) and laparoscopic end-to-end (EEA) anastomosis. Methods: RYGBP was performed in 15 pigs. Depending on the technique used to create the gastro-jejunostomy, the pigs were divided in 3 groups. In group A, a standard two-layer hand-sewn anastomosis were performed. In group B and C, gastro-jejunostomies using EEA (B) or SurgASSIST (C) were attempted. Operation time, intraoperative technical failure, postoperative anastomotic leakage, and necropsy results were measured. Results: 14 pigs survived surgery. One leakage from the gastro-jejunostomy was detected intraoperatively in group B. There was no evidence of leakage postoperatively from the proximal gastro-jejunostomy in any groups. No statistical difference was found between the groups concerning the operation time or the diameter and degree of healing of the anastomosis. Conclusion: We found the SurgASSIST system safe for performing gastro-jejunostomies in laparoscopic RYGBP. There were no anastomotic failures intra- or postoperatively. At necropsy, there was no evidence of anastomotic stricture or delayed healing processes.
