To the Editor,
We read with great interest the recently published paper by Sabuncuoglu et al1 entitled “Eyedrop-shaped, modified Limberg transposition flap in the treatment of pilonidal sinus disease.” We would like to congratulate the authors and thank them for sharing their experiences with us. We think that the procedure of eyedrop technique will reduce wound tension and increase postoperative patient comfort. It is a very good initiative.
Different surgical treatment procedures for pilonidal disease have been described and tried, with numerous reports comparing these procedures being available in the literature. The results of these studies2 are on the same line as Sabuncuoglu et al.1
However, information on the comparison of the most common surgical procedures, including flap technique and others, with respect to quality of health and patient satisfaction criteria, is scarce.3
A wide intergluteal depth, bathing habituation, sitting time, hairy rate, body mass index, and genetic predisposition have been shown as the predisposition factors of sacrococcygeal pilonidal sinus disease by some authors.4 In the light of all the facts mentioned above, we think that the predisposition and risk factor rates of the patients, reported in the study by Sabuncuoglu et al1, can help us explain the results more explicitly. This study recommends us to make a comparison between eyedrop technique and other surgical procedures. We think that a comparison of the results of these two techniques, with respect to the criteria of quality of life and patient satisfaction, would lead us to the next step in the treatment of this disease.
Thank you for contributing your ideas to our study.1 Predisposing factors of pilonidal sinus disease (PSD) is an important issue, which should be emphasized. Karydakis2 reported that three factors are important in the process of hair insertion namely: (1) the invader that consists of loose hair, (2) the potency that results in hair insertion, and (3) the vulnerability of the skin to hair placement at the depth of the natal cleft. PSD occurs frequently between the ages of 15 years and 25 years, and is rare both before puberty and after the age of 40 years.3 Additionally, male gender, a high body mass index (BMI), deep natal cleft, professions requiring prolonged sitting, deep natal groove, excessive body hair, excessive sweating, and bad sanitary condition have been described as the risk factors.4
In our case series, consistent with the literature, the mean age was 25.8 years. However, only one patient was 45-year old. Male gender was dominant (90.1%). Four patients were associated with professions requiring prolonged sitting. Bad sanitary conditions were the predisposing factors in 62 patients. In addition, fecal contamination was seen in one patient who had wound dehiscence.
No relation was mentioned between family history and PSD in the study of Harlak et al,5 who analyzed previously proposed risk factors. However, in our series, three patients had a family history of PSD. Doll et al6 demonstrated that a family history of PSD predisposes to an earlier onset of disease and a 50% long-term recurrence rate. In our study, five patients experienced recurrence (4.5%) and one of them had a family history of PSD.
Cubukcu et al7 reported that obese patients with a high BMI (mean 29.35) have a higher risk of recurrence of PSD after surgical intervention than those with a lower BMI. In our series, for patients who experienced recurrence, BMI was < 30 kg/m2. We observed that the recurrence rate was high in patients with poor wound care and who do not pay attention to warnings. In patients with a high BMI, surgery should be considered after weight loss due to difficulty in maintaining personal hygiene and deep natal cleft.
