Umbilical Pilonidal Sinus Disease: Predisposing Factors and Treatment

Pilonidal sinus disease is a common problem of sacrococcygeal region. However, it is also observed in the periumbilical area. There are only a few reports about umbilical pilonidal sinus in the literature. In this study, 26 patients (24 men (92 %), 2 women (8 %) with a mean age of 22 years) with umbilical pilonidal sinus disease were included. Predisposing factors, patient characteristics, treatment modalities, and their results have been studied. Male sex, young age, hairiness, deep navel, and poor personal hygiene were found to be predisposing factors. Twenty-five patients were treated conservatively. However, two patients failed to respond to conservative treatment. Those patients underwent surgery where umbilectomy was carried out without reconstruction. One patient was also operated on for the preoperative misdiagnosis of irreducible umbilical hernia. Patients were followed for 14–96 months. We recommend conservative treatment in patients with umbilical pilonidal sinus. Surgery should be performed in recurrent cases resistant to conservative treatment. The importance of differential diagnosis of umbilical pilonidal sinus from other umbilical pathologies is also emphasized.     

Outcomes of Conservative Treatment of 134 Cases of Umbilical Pilonidal Sinus

Background

There are different opinions about the treatment of umbilical pilonidal sinus. The aim of the present study was to evaluate the outcome of conservative treatment of this disease.

Methods

All patients with umbilical pilonidal sinus who attended our private surgical clinic in Erbil, Kurdistan, from January 1997 to August 2011, were treated by conservative treatment. Umbilectomy was performed for those who did not respond to the conservative treatment after three sessions.

Results

A total of 134 patients were seen; 121 (90.3 %) were men. Only 105 (78.35 %) patients came back for the second visit. Eighty of them (76.19 %) responded to the treatment. The other 25 (23.8 %) patients were retreated by a second session of conservative treatment. Of these 25 patients, 19 (76 %) came back for the third visit and only three (15.78 %) patients did not respond to the treatment. One patient insisted on umbilectomy. The other two patients were treated but did not respond to the third session treatment. Umbilectomy was performed for them. Hair was found in the sinus after excision in these three patients. The follow-up period ranged from 9 months to 6.5 years for 46 (34.32 %) patients and revealed no recurrence.

Conclusions

Conservative treatment should be regarded as the first choice and the main method of treatment in the management of umbilical pilonidal sinus. Improper extraction of hair is the main cause of failure of conservative treatment. Recurrence can be prevented by giving the patients instructions on preventive measures.     

Effectiveness of Collagenase in the Treatment of Sacrococcygeal Pilonidal Sinus Disease

Purpose: Sacrococcygeal pilonidal sinus disease (SPSD) is a disease affecting young patients, which results in a long-term loss of productive power, and also tends to have high rates of morbidity since it has no ideal treatment. The main purpose of this study was to investigate the effectiveness of topical collagenase in the treatment of SPSD. Methods: In the present study, 40 patients admitted to our department were separated into two groups. Excision and marsupialization with dressing by bacterial collagenase was performed in the first group, while the treatment was excision and marsupialization without dressing by bacterial collagenase in the second group. Results: We determined that the healing in terms of the width and depth of the wound in the first week and in depth of wound in the second week was better in group 1 than in group 2 (P = 0.040, P = 0.020, P = 0.048, respectively). The duration of wound healing was 21.9 ± 1.3 days in group 1, and 28.1 ± 1.3 days in group 2 (P = 0.0001). The recurrence rate in the intergluteal area, which heals by granulation and has no hair follicles, tends to decrease when a partial closure is obtained. Conclusion: We therefore recommend an excision, marsupialization, and dressing with bacterial collagenase, in cases with noncomplicated SPSD.

Pilonidal Sinus Treated by Z-Plasty1

The rationale and technique of Z-plasty treatment for sacro-coccygeal pilonidal sinus are presented. Z-plasty achieves healing by primary intention, and by modification of the local environment prevents recurrence.     

Etiological Factors in Umbilical Pilonidal Sinus

The objective of this study is to investigate factors leading to the development of umbilical pilonidal sinus (UPS). 31 patients with UPS treated at Harran University and Keçiören State Training Hospital between January 1997 and November 2007. 100 consecutive volunteer outpatients were administered questionnary. The questionnary included questions on age, sex, profession, body mass index (BMI), skin color, hirsute status, frequency of taking baths, personal history of pilonidal sinus (PS), familyal history of PS, and whether –they wear tight clothes and wheteher they use belt. The results obtained from two groups were compared. UPS is one of the PS group diseases and involves umbilical region. There was statistically significant difference between the patient and control groups in terms of age, profession, hirsute status, familial history of PS, wearing tight clothes and BMI. Improvement in these factors may contribute to the reduction of the prevalance of the disease.     

Long-Term Epilation with Long-Pulsed Neodimium:YAG Laser

BACKGROUND: Unwanted body hair can represent a severe cosmetic disturbance. The traditional methods used to epilate often have limitations, side effects, and unsatisfactory results. In recent years, various light sources (lasers and others) have been developed for long-term epilation of unwanted hair. OBJECTIVE: This study evaluates, on a large number of patients, the efficiency and safety of a long-pulsed low-potency Nd-Yag laser invented specifically for long-term hair removal. METHODS: Some 208 subjects needing epilation were divided into three groups and treated during an 11-month period. Group A included 79 patients with a normal distribution of unwanted hair; Group B 67 patients with constitutional hypertrichosis; and Group C 62 patients with hirsutism. Treatment sessions were performed with a fluence of 23-56 J/cm2 at 1-month intervals until obtaining desirable results. Follow-ups ranged from 1 to 6 months. In 3 patients 4-mm diameter punch biopsy specimens were obtained before the first session and again after 6 hours. A third biopsy was performed after 3 months. RESULTS: Every session resulted in a 20-40% hair loss, depending on the color of hair. Complete epilation was obtained in 4 to 6 sessions. Only white hair was not receptive to laser light, and its growth was not modified. No patients, including dark-complexioned patients, had blistering, hypo-or hyperpigmentation. No pain was present during treatment except for the axillary area. In the specimen obtained after 6 hours, very extensive necrosis of the hair follicular and sebaceous gland epithelium was evident. Histologic findings of the biopsies taken after three months showed complete disappearance of hair and moderate fibrosis. CONCLUSION: This study proves that the long-pulsed Nd:Yag laser treatment produces an excellent prolonged epilation with no relevant side effects. This laser light, having a 1064 nm wavelength, is minimally absorbed in superficial skin layers, and pronounced scattering up to 5 mm occurs targeting the deeper follicles.

Karydakis Flap for Recurrent Pilonidal Disease

Background

Patients undergoing surgery for recurrent pilonidal disease are at high risk of developing re-recurrence. The present retrospective analysis was performed to compare long-term results in patients with recurrent disease undergoing midline excision surgery compared to patients undergoing the Karydakis flap procedure.

Methods

Only patients with previous excision surgery apart from simple abscess incision were included. Disease recurrence was defined as the need for repeat surgery.

Results

A total of 124 patients underwent surgery for recurrent pilonidal disease. Group 1 consisted of 37 patients (25 excision + midline closure, 12 excision + lay-open). Group 2 consisted of 87 patients (Karydakis flap). There were no statistically significant differences between the groups with regard to patient’s age, duration of disease, body mass index, or sex. The average number of previous surgeries was significantly higher in group 1 patients (2.1 vs. 1.8, p = 0.019). The overall 1-year recurrence rate was 43 % in group 1 and 3 % in group 2 (p < 0.0001). The wound dehiscence rate after the Karydakis flap procedure was as high as 43 % between years 2005 and 2009, but it fell to 10 % thereafter (p = 0.02).

Conclusions

Karydakis flap procedure is superior to midline excision surgery in patients presenting with recurrent pilonidal disease.     

Modified Limberg Transposition Flap for Sacrococcygeal Pilonidal Sinus

Purpose. To investigate the results of wide rhomboid excision with Limberg transposition flap reconstruction to treat pilonidal sinus.Methods. We analyzed the well-documented records of 238 patients with sacrococcygeal pilonidal sinus who underwent wide excision with a Limberg transposition flap and were followed up for longer than 1 year postoperatively. After the first 40 operations, we modified this flap reconstruction by tailoring the rhomboid excision asymmetrically to place the lower pole of the flap 1–2cm lateral to the midline. Wound infection rates, hospitalization, time required for free mobilization, and recurrence rates were recorded.Results. Postoperative infection developed in two patients (0.8%), which was easily managed by wound care, antibiotics, removal of skin staples, prolonged drainage, or a combination of these treatments. The mean hospitalization was 2.10 ± 0.20 days (range 1–3 days), and the mean time required for recovery and return to daily activities was 8.00 ± 2.50 days (range 4–17 days). There were only three recurrences (1.26%) after a mean follow-up of 29.20 ± 3.10 months (range 12–38 months). Since we started performing our modification of the technique by lateralization of the inferior apex, no further recurrences have been seen. The recurrence rate differed significantly between the classical Limberg flap group and the modified Limberg flap group (P = 0.004)Conclusion. These results provide further evidence that wide excision with a Limberg transposition flap reconstruction is an effective surgical method for primary or recurrent pilonidal sinus, associated with a low complication rate, short hospitalization and disability, and a low recurrence rate. A modification of the technique was devised to further enhance wound healing and reduce the risk of recurrence.     

Pilonidal Sinus Disease Treated by Depilation Using an 800 nm Diode Laser and Review of the Literature

BACKGROUND: Pilonidal sinus disease is a debilitating, disfiguring chronic ailment that is often resistant to therapy. Its etiology and treatment remain in question. OBJECTIVE: To assess the efficacy of an 800 nm diode laser in the treatment of recalcitrant pilonidal sinus disease. METHODS: Two patients with recalcitrant pilonidal sinus disease were treated in the lower back, buttocks, and perigluteal cleft area with an 800 nm diode laser with a spot size of 9 x 9 mm, fluences of 30 to 48 J/cm2, and pulse widths of 15 to 24 milliseconds. RESULTS: Long-term relief of pilonidal sinus disease was produced with as few as two treatments 2 months apart to as many as six treatments over a 2-year period. With each successive treatment, fewer pulses were needed and the interval between treatments increased. CONCLUSION: The 800 nm diode laser may be an effective tool in the treatment of pilonidal sinus disease. By eliminating the source of hair and hair fragments that course along the surface of the lower back and buttocks, interruption of the etiologic source for pilonidal sinus disease can be accomplished.     

Minimally Invasive Treatment of Pilonidal Disease: Crystallized Phenol and Laser Depilation

Pilonidal disease has been treated surgically and by various other methods for many years. The most important problem associated with such treatment is recurrence, but cosmetic outcome is another important issue that cannot be ignored. Today, crystallized phenol is recognized as a treatment option associated with good medical and cosmetic outcomes. We hypothesized that the addition of laser depilation to crystallized phenol treatment of pilonidal disease might increase the rate of success, and this study aimed to determine if the hypothesis was true. Patients who were treated with crystallized phenol and 755-nm alexandrite laser depilation were retrospectively analyzed. In total, 42 (31 male and 11 female) patients were treated with crystallized phenol and alexandrite laser depilation and were followed up between January 2009 and January 2012. In all, 38 patients (90.5%) had chronic disease and 4 (9.5%) had recurrent disease. Among the patients, 26 (61.9%) recovered following 1 crystallized phenol treatment, and the remaining patients had complete remission following repeated treatment. Some patients needed multiple treatments, even up to 8 times. None of the patients had a recurrence during a mean 24 months (range, 6–30 months) of follow-up. Whatever method of treatment is used for pilonidal disease, hair cleaning positively affects treatment outcome. The present results support the hypothesis that the addition of laser depilation (which provides more permanent and effective depilation than other methods) to crystallized phenol treatment (a non-radical, minimally invasive method associated with very good cosmetic results) can increase the effectiveness of the treatment and also reduce the recurrence rate of the disease.     

Evaluation of the Outcome of Complete Sinus Excision with Reconstruction of the Umbilicus in Patients with Umbilical Pilonidal Sinus

Umbilical pilonidal sinus is a cause of umbilical discharge. In this study, the outcome of complete excision of the umbilical sinus with umbilical reconstruction is considered. Adult patients with umbilical pilonidal sinus who had not undergone any previous surgeries were operated on using a technique that involves complete excision of the sinus after eversion of the umbilicus followed by reconstruction of the umbilicus. Patients were then followed; and wound complications, recurrence, and patient satisfaction were evaluated at postoperative visits. A total of 45 patients underwent the operation; 39 (86.5%) were male, and 6 (13.5%) were female. The mean age was 22.6 years (18-27 years). Six male patients had synchronous sacrococcygeal pilonidal disease. The mean follow-up period was 34 months (3-62 months). Only four patients had wound drainage after operation, and all required drainage of the wound. No recurrence was observed during the follow-up period, and all patients were satisfied with the appearance of their umbilicus. The technique of complete sinus excision and umbilical reconstruction is an effective and acceptable method for treating umbilical pilonidal sinus and may be recommended for primary treatment of this disease.
