Objective To summarize the methods of diagnosis and treatment for sacrococcygeal pilonidal sinus. Methods The processes of diagnosis and treatment for 84 patients with sacrococcygeal pilonidal sinus were analyzed retrospectively. The incision and primary suture with mattress-suture and exterminated dead space was performed in 36 patients （without recurrence and the length of fistulous tract was less than 5 cm）. The sinus resection and incision open surgery with excision of fully pathology tissue and regional treatment with Kangfuxin liquid was performed in 48 patients （with recurrence and the length of fistulous tract was more than 5cm）. Results Two cases were recurrent after half a year and cured with sinus resection and incision open surgery and regional treatment with Kangfuxin liquid in the incision and primary suture group. The others were disposable healing. The healing time in the incision and primary suture group was from 14 to 35d， the mean time was 26d， which in the other group was from 30 to 45d， the mean time was 37d. Follow-up for more than one year， none of recurrence happened. Conclusion Perfecting inspection before surgery， clarifying a diagnosis， choosing a suitable surgical treatment， and perioperative care could cure the disease and extremelyreduce recurrence.
ObjectiveTo compare the clinical therapeutic efficacy of the pilonidal sinus with four kinds of surgical procedures. MethodsThe clinical data of 43 patients with sacrococcygeal pilonidal sinus treated from January 2008 to March 2013 were analyzed retrospectively. All of them were received surgery, in who 4 patients underwent pilonidal sinus resection alone(incision open group), 7 patients underwent incision and direct suturing after pilonidal sinus resection (incision and direct suturing group), 19 patients underwent marsupialization after pilonidal sinus resection(marsupialization group), and 13 patients underwent Limberg flap transposition after pilonidal sinus resection(rhombus flap transposition group). Results①There were not statistically significant differences regarding demographics among four groups (P > 0.05). 2 The hospital stay was(16.70±8.69) d, (16.43±10.68) d, (15.84±11.29) d, and(14.69±4.01) d in the incision open group, incision and direct suturing group, marsupialization group, and flap transposition group, respectively, and the healing time of incision was(64.75±6.50) d, (34.57±19.15) d, (35.16±15.49) d, and(17.92±4.29)d among the same four groups, respectively. The difference of the hospital stay was not statistically significant among four groups(P > 0.05). The healing time of incision in the flap transposition group was less than that in the other three groups(P < 0.05), which in the incision and direct suturing group and marsupialization group were shorter than those in the incision open group(P < 0.05), and which had no significant difference between the incision and direct suturing group and marsupialization group(P > 0.05).③The partial wound dehiscence occured in two patients and the wound was partially broken because of infection in two patients in the incision and direct suturing group. One patient was performed drainage because of emhysis and the wound tension blisters occurred in one patient in the flap transposition group. There was no complications in the other two groups. There was no recurrence after the wound healing of follow-up six months. ConclusionsAccording to this limited preliminary data, the selection of wound closure method depends on the incision tension. Direct suturing can be the choice for incision with lower tension. The marsupialization can be the choice for incision with higher tension. The Limberg flap transposition can be the choice for incision with extensive disease or postoperative recurrence.

Objective To investigate short-term clinical outcomes of double-modified Limberg flap transplantation in treatment of sacrococcygeal pilonidal sinus. Methods One hundred patients with sacrococcygeal pilonidal sinus from October 2010 to May 2015 in this hospital were included, and subsequently were divided into double-modified Limberg flap transplantation group (double-modified flap group,n=30), classical Limberg flap transplantation (classical flap group,n=30), and interrupted suture after resection group (interrupted suture group,n=40). The duration of operation, intraoperative bleeding, hospital stay, duration of return to work, recurrence rate, and incision complications rate were compared among these three groups. Results ① The age, gender, body mass index, and preoperative complications had no significant differences among these three groups (P>0.05). ② The intraoperative bleeding and the hospital stay had no significant differences among these three groups (P>0.05). Compared with the interrupted suture group, the durations of operation were significantly longer (P<0.05), the durations of return to work were significantly shorter (P<0.05), the recurrence rates were significantly lower (P<0.05) in the double-modified flap group and the classical flap group. The above indicators had no significant differences between the double-modified flap group and the classical flap group (P>0.05). ③ The incision hematoma and the part disruption of incision had no significant differences among these three groups (P>0.05). Compared with the interrupted suture group, the rates of incision infection and incision complete disruption were significantly lower (P<0.05) in the double-modified flap group and in the classical flap group. The incision maceration of the classical flap group was significantly higher than that of the interrupted suture group (P<0.05) or the double-modified flap group (P<0.05). No skin flap necrosis occurred in the double-modified flap group and the classical flap group. Conclusions Double-modified Limberg flap transplantation and classical Limberg flap transplantation have less complications and lower recurrence rate than interrupted suture after resection. Compare with classical Limberg flap transplantation, double-modified Limberg flap transplantation has a lower incision maceration rate. Because of limitation of sample size in this study, long-term clinical efficacy of double-modified Limberg flap transplantation needs to be confirmed by multicenter randomized controlled trials.
ObjectiveTo summarize the clinical progress of minimally invasive techniques in treatment of pilonidal disease.MethodThe relevant literatures about minimally invasive techniques in the treatment of pilonidal disease in recent years were reviewed.ResultsAbout hair removal and carbolic acid injection, they had less damage, fewer complications, higher recurrence rate compared to other surgery, and did not affect the second treatment. The fibrin injection could not clarify its role in the treatment of pilonidal disease due to some defects in the clinical design. Bascom Ⅰhad the advantages of fast recovery and no need for hospitalization, with a recurrence rate of 8%–16%. According to the results of some current clinical researches, it was a promising operation. Sinus resection required further clinical evaluation due to the limited results of current researches. A clinical study of more than 1 000 cases over 10 years showed that the recurrence rate in 10 years was 16%. Compared with frequently used pilonidal operations, the trephine technique was associated with a lower recurrence rate and a lower incidence of postoperative complication. Some short-term clinical researches showed that endoscopic pilonidal sinus treatment was a safe, minimally invasive, and less complication treatment.ConclusionsCompared with frequently used pilonidal operations, minimally invasive technique has the advantages of shortening the hospital stay, shortening the healing time, and reducing complications. It is worth of application.
Objective To investigate the feasibility and effectiveness of fascial tissue flaps and skin flaps with layered sutures for repairing wounds after excision of sacrococcygeal pilonidal sinus. Methods Between March 2019 and August 2022, 9 patients with sacrococcygeal pilonidal sinus were admitted, including 7 males and 2 females with an average age of 29.4 years (range, 17-53 years). The disease duration ranged from 1 to 36 months, with a median of 6 months. There were 7 cases with obesity and dense hair, 3 cases with infection, and 2 cases with positive bacterial culture of sinus secretion. The wound area after excision ranged from 3 cm×3 cm to 8 cm×4 cm, with a depth of 3-5 cm, reaching the perianal or caudal bone; there were 2 cases with perianal abscess formation and 1 case with caudal bone inflammatory edema. Enlarged resection was performed during operation, and the fascial tissue flap and skin flap were designed and excised at both left and right sides of the buttock, ranging from 3.0 cm×1.5 cm to 8.0 cm×2.0 cm. A cross drainage tube was placed at the bottom of the wound, and the fascial tissue flap and skin flap were advanced and sutured in three layers, namely, 8-string sutures in the fascial layer, barbed wire reduction sutures in the dermis, and interrupted skin sutures. Results All 9 patients were followed up 3-36 months, with an average of 12 months. All incisions healed by first intention, and no complication such as incisional dehiscence or infection in the operative area occurred. There was no recurrence of sinus tracts, the shape of gluteal sulcus was satisfactory, both sides of buttocks were symmetrical, local incision scar was concealed, and the shape disruption was minimal. ConclusionFascial tissue flaps and skin flaps with layered sutures for repairing wounds after excision of sacrococcygeal pilonidal sinus can effectively fill the cavity and reduce the incidence of poor incision healing, with the advantages of small trauma and simple operation.
