ABSTRACT

Objective To compare the clinical efficacy of the flaps of modified Limberg and direct incision followed by suture in the treatment of sacrococcygeal pilonidal sinus,aiming to provide the academic guide for its clinical surgery.Methods A total of 76 patients suffered from sacrococcygeal pilonidal sinus were treated with two surgical methods in Department of General Surgery and Department of Burn and Plastic Surgery in Sixth Medical Center of PLA General Hospital from 2013 to 2017.Among these patients,37 cases were resected and reconstructed using the flaps of modified Limberg,the other 39 cases were sutured after beingresected.These patients were followed up during the next 1 or 2 years.Five indexes including surgery period,length of hospital stay,postoperative infection,recurrence and complication,were investigated to statistically compare two different surgery methods' efficacy,using independent t test or chi-square test respectively.Results There were 76 patients in the Limberg flap group and the direct suture group,the operation time was about one and a half hours,and the hospitalization time was about 15 days (P＞0.05);there was no statistical difference between them.There were no complications in 35 of the 37 patients in the Limberg flap group,but skin cracking and infection in 2 patients.In the direct suture group,there were 39 patients,16without complications and 23 with complications,(x2=1133.2393,P=0.0000);there were statistical differences.Among the 37 patients in the Limberg flap group,only one recurred;among the 39patients in the direct suture group,9 recurred (x2=1192.9211,P=0.0000);there were statistical differences.Conclusions Limberg flap incision shows good healing and fewer complications.Within the group of Limberg flap incision healing,only few cases of recurrences occur after the surgery.It not only effectively reduce the complication rate in patients,but also release the pain from long-term,reduplicated medication.The author proposes that this operation should be promoted in the future clinical practice.
