Abstract: Objective  To evaluate the efficacy and safety of the Limberg flap transposition technique in the treatment of sacrococcygeal pilonidal sinus .Methods A total of 110 patients diagnosed with sacrococcygeal pilonidal sinus at our hospital between January 2022 and August 2023 were enrolled.They were divided into two groups according to the surgical procedure:50 patients in the control group underwent conventional pilonidal sinus excision,whereas 60 patients in the observation group received the Limberg flap transposition procedure.Postoperatively,recovery time,inflammatory indices,pain scores,and complications were compared between the two groups. Results The postoperative hospital stay of the observation group was (8.98±3.15) days,which was longer than that of the control group (7.24±3.54) days.The postoperative wound healing time of the observation group was (9.95±2.96) days,which was shorter than that of the control group (29.78±2.18) days.There was a statistically significant difference between the two groups (P<0.05).The white blood cell count (WBC) in the observation group was (6.34±0.38)×109/L,C-reactive protein (CRP) was (1.89-0.28 mg/L),which was lower than the control group[(7.56±0.54)×10⁹/L 、( 2.47±0.47)mg/L].There was a statistically significant difference between the two groups (P<0.05).The pain scores of the observation group at 24 hours and 36 hours after the operation were (5.32±1.03) points and (2.10±0.34) points respectively,which were lower than those of the control group [(6.29±1.13) points and (4.48±1.12) points] respectively.There was a statistically significant difference between the two groups (P<0.05).With respect to postoperative complications,the observation group experienced 5 cases of wound infection,8 cases of wound dehiscence,and 11 cases of tension blisters;no recurrence was observed during the follow-up period.In the control group,four patients developed recurrence,whereas no cases of wound infection,dehiscence,or tension blisters were recorded.The recurrence rate was significantly lower in the observation group,although the incidence of postoperative complications was higher;the difference between the groups (except for incision infection) was statistically significant (P<0.05).Conclusion The Limberg flap transposition technique for sacrococcygeal pilonidal sinus shortens postoperative recovery time,attenuates the inflammatory response,alleviates pain,and reduces the risk of recurrence.
