Background: To observe if absorbable suture can effectively and safely be used to close the mesenteric defect after Roux-en-Y reconstruction. Methods: Rats were randomly assigned to 5 experimental groups according to different suture materials used in closing the mesenteric defects (Peterson’s space) after Roux-en-Y gastric bypass. Group A (control group), Group B (non-absorbable suture, Prolene suture), Group C (biological glue), Group D (non-absorbable suture, polyester suture) and Group E (absorbable suture). All rats were followed up for 8 weeks postoperatively and underwent laparotomy to observe the degree of adhesion and closure of the mesenteric defect. Results: No significant difference was found in the decrease in food intake and body weight among all groups. No internal hernia (IH) occurred in any group. The mesenteric defects of Group A remained completely visible without any closure or adhesion. Multiple gaps were found between Prolene suture and the mesentery along the suture line in Group B. The mesenteric defects of Group C were complete closed with multiple adhesions of the small intestine and the greater omentum. The mesenteric defects had closed completely in both Group D and Group E. Average adhesion score of Group A and Group B was 0 and 0.33±0.52 respectively. Average adhesion score was higher in group C (3.83±0.41) than the other groups (p＜0.05). Group D and E had similar average adhesion score, 3.17±0.41 and 3.00±0.00 respectively. Conclusion: Absorbable sutures can be effectively and safely used to close the mesenteric defect in a rat model.
