Background: Ozone is a three-oxygen molecule (O3). Ozone therapy
(OT) is systematically effective when pathological inflammatory
and immunologic processes are activated. Among of these conditions
are wound healing, macular degeneration related to aging, and conditions
that are ischemic or infectious.
Aims: The aim of this study was to determine the effects of OT on
wound healing of intestinal anastomosis in the presence of peritonitis
in a rat model.
Study Design: Animal experimentation.
Methods: A total of 40 Wistar albino rats were randomized into four
groups (n=10) including: sham (S), peritonitis (P), ozone 0 (O0), and
ozone 24 (O24). In group S, only cecal dissection was carried out.
The S group had only a cecal dissection and intestinal anastomosis
performed, but no peritonitis. In all other groups, cecal ligation
and puncture (CLP) followed the cecal dissection to induce bacterial
peritonitis. 24 h after puncture, a cecal resection and ileocolic anastomosis
were performed. In group P, 24 h after CLP, a cecal resection
and ileocolic anastomosis were performed and no ozone was administered.
In group O0, immediately after the anastomosis, and in group
O24, starting 24 hours after the anastomosis, an intraperitoneal 1 mg/
kg/day ozone administration was applied for seven days. On the seventh day the animals were sacrificed, the anastomotic bursting pressures
(BP) and the hydroxyproline values of the anastomotic tissues
were measured, and histopathologic examination of the anastomotic
segment was carried out.
Results: The highest BP was in group S, with 211±23.13 mmHg. The
mean BP of group P was 141±56.25 mmHg, which was significantly
lower than in the other two peritonitis groups that received ozone
therapy, group O0 and O24, where it was 192±22 and 166±45 mmHg,
respectively (p<0.05). The difference in the BP between groups O0
and O24 was not statistically significant (p>0.05). Histopathologic
analyses of the anastomotic segments determined there was significantly
more oedema and necrosis in the control group rats, and collagen
deposition in the anastomotic tissue was significantly higher
in the ozone-treated groups on postoperative day 7. Hydroxyproline
levels were significantly higher in groups O0 and O24 compared to
the peritonitis group (P).
Conclusion: Ozone therapy has a beneficial effect on anastomotic
healing of the colon in the presence of peritonitis.
