Five different kinds of
sutures which can be used for closure of the rectal stump in Hartmann's operation are evaluated in the same animal. They are compared at six different phases of the
cicatrization process: 7-30-45-60-90 and 150 days. In the analysis, the degree of complete
cicatrization is considered as well as the thickness of the cicatriced tissue, and other factors such as persistence of
suture material and the result of it. All of the
sutures involved accomplished the goal of a good joint of the planes of intestinal
suture. Although, two of them, the
metal stapler and
Polyglactin (
Vicryl) in extramucosal surgery fulfill almost in an ideal way the goals concerning security, rare reaction to
suture material, and consequently less thickness in the cicatriced tissue (2 x 2 and 1 x 1 mm respectively) as well as complete
cicatrization in ninety days. Stapler is performed quicker and in a more aseptic way, but the
scar resulting from
Polyglactin is smaller. In separate extramucosal points,
silk produces a more important tissue reaction with a thicker
scar (3 x 3 mm) coming to an end in 150 days. "Albert Lembert" type
suture is really far away from being a good mean because it creates an important tissue reaction with a thick
scar (3 x 3 mm), with late consolidation (150 days) and granulomatous reaction. Resorbable stapler--Polisorb--has a considerable volume and it causes an important tissue reaction which determines a very thick (4.5 x 4.5 mm) and "unfinished"
scar within 150 days; really far away for practical use.
