Résumé:
"Wound repair and healing are constant problems in surgery. The surgeon makes more
incisions in the abdomen than in any other region. It must be concerned with the best repair
methods.
The objective of our work was to compare the effect of different suturing techniques
on the strength and resistance of the midline laparotomy wound to intra-abdominal pressure
and the quality of the scar in order to identify the suture technique that allows the strongest
scar and gives the optimal healing. 40 female Wistar rats divided into groups of 5 individuals
were used in the study. Four suturing techniques have been used to reconstruct the medial
laparotomy wound. The time required and the length of thread used for each technique were
recorded. The resistance of the wound to dehiscence was measured by inserting a balloon into
the abdomen and filling it with air until the burst of the abdomen. The scar of the laparotomy
wound was examined and the quality of the scar and its resistance were evaluated. Pressure
was measured in millimeters of mercury.
Results show that realization of continuous suture techniques needs less thread and
requires a shorter time compared to interrupted sutures techniques.
The Reverdin suturing technique is more resistant to pressure compared to other
techniques and after seven days the quality of the scar is better in continuous sutures
techniques.
