OBJECTIVE

Evaluation of the effectiveness of various surgical techniques, comparison of their results and study of the effect of polymer hydrogel on treatment outcomes.

METHODS

The study included 97 patients with a diagnosis of recurrent or complex PSD (Pilonidal sinus disease). Patients were divided into 3 groups who underwent surgery using the traditional Limberg flap, modified Limberg flap, or operated using modified Limberg flap and polymer hydrogel in the coloproctology department of the A.S. Loginov International Research Center from March 2015 to September 2023. The incidence of complications in the early postoperative period and the frequency of relapses in the late period were assessed.

RESULTS

97 patients were included in the study; long-term results were observed in 84 patients (86.6%). 88.7% of them are men, 11.3% are women. There were no statistically significant differences in the incidence of complications in the early postoperative period between the groups (p=0.374). The recurrence of the disease in patients who underwent traditional plastic surgery was 10.9%. In the group with modified plastic surgery, recurrence was detected in 2 patients (4.9%). In the group with the use of polymer hydrogel, 1 case of recurrence (2.5%) was recorded. There are no statistically significant differences in the following parameters: average blood loss, duration of hospitalization, indicators of postoperative control, and the level of inflammatory markers. There were no intraoperative complications in any of the groups.

CONCLUSION

Modified plastic using a polymer hydrogel to eliminate “dead zones” and avoid drainage in the postoperative period has demonstrated its effectiveness, however, further studies are required to confirm the results obtained.
