Overview
Aim:
A technique of approximative anastomosis in witch integrity and continuity of bowel is achieved with limited number of interrupted seromuscular stitches was evaluated in experimental study.
Material and methods:
Small bowel anastomosis were performed in twelve rats (Wistar, male) with weight range 197–242 g. An approximative anastomosis in the ileum of six rats was performed with five seromuscular-interrupted sutures only; in the second study group anastomosis was performed with conventional technique of interrupted sutures. The approximative anastomosis was evaluated concerning operating time, anastomotic healing, bursting pressure and adhesions in comparison to the conventional anastomosis. Statistics was calculated with Anova test.
Results:
All anastomosis in both group healed well without obstruction. The median operating time needed for approximative anastomosis was shorter (31.7 ± 1.6 minutes versus 35.2 ± 1.5 minutes, p = 0.002). The strength of approximative anastomosis after 7 days was 249 ± 39 torr; strength of standard anastomosis was 218 ± 23 torr (p = 0.118). There were no significant differences in the others evaluated parameters between two study groups.
Conclusion:
In the animal model presented, the approximative anastomosis shows time saving alternative to standard anastomosis, with the same parameters of anastomotic strength, healing, and adhesions.
Key words:
aproximative anastomosis – conventional anastomosis – anastomotic strength – multifocal necrotizing enterocolitis
