Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
There are various surgical and non-surgical methods for its treatment. Many different surgical techniques have been defined. None of these surgical techniques are defined as 'gold standard'.
For many years, wide excision and secondary healing was the standard approach for pilonidal sinus disease. However, when this method resulted in prolonged healing and restriction of regular activities, various reconstructive methods were developed to demonstrate the disadvantages of secondary healing.
A minimally invasive treatment modality for pilonidal sinüs dissease is excision of the sinus pit(s) followed by application of phenol to the sinus tract. Phenol is a sclerosing agent that destroys the epithelium and debris in the sinus, and is, thus, able to promote healing of the sinus.
Recently, advances in laser technology have made laser ablation of the sinus tract possible. The aim is to destroy and obliterate the sinus tracts with thermal energy produced by the laser probe.
The aim of this prospective observational study was to compare phenolization and laser ablation in the treatment of pilonidal sinus disease.
Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
Although its cause re mains unknown, the increased hormone levels associated with puberty, the growth of thick hair, long periods of sitting, and friction imparted by tight-fitting clothing may be in play. Other risk factors are hirsutism, obesity, and a family history of the disease. As the cause of the dis ease, hairs falling from head, neck, and back are placed in the intergluteal area and hairs that penetrate the skin initiate foreign body reactions. In the affected area, the hairs are moist, sweaty, and unhygienic, readily trig gering development of the subcutaneous skin cysts and sinuses characteristic of the disease, which (in the gluteal region) present as asymptomatic pits, painful abscesses, or sinuses associated with purulent serous discharge.
The acute phase is characterized by sacral abscess, and during the chronic phase cyst formation or persistent sinus discharge may be observed. At present, no consensus exists regarding the best treatment choice, but conservative treatment can only control the symptoms, and most patients have to undergo operation. Traditional surgery has good success rates; it requires removal of all diseased skin and subcutaneous tissue, including wide excision and healing by secondary intention or reconstructive ("flap") techniques, which results in a long recovery time and a large wound. In recent years, minimally invasive surgical methods for the treatment of SPD (such as endoscopic pilonidal sinus ablation, laser ablation, phenolization, or fibrin glue injection) have improved, reducing wound scarring and pain and shortening the time it takes for patients to return to their normal lives. Surgical success is evaluated by recovery time, the time to return to daily activities, and the complication and recurrence rates.
Patients presenting with pilonidal sinus disease at the Department of General Surgery, Mersin University (Türkiye) were evaluated for participation in this study. Patients aged ≥18 years with symptoms related to pilonidal sinus disease were included in this study. A power analysis was performed using the G\*Power (v3.1.7) program to determine the sample size.
Exclusion criteria include the absence of symptoms associated with pilonidal sinus disease, suspicion of an extensive subcutaneous sinus tract network, and the presence of a pilonidal abscess and previous surgery for pilonidal sinus disease, recurrent and complicated pilonidal sinüs disease.
At least 64 patients who meet the inclusion and exclusion criteria will be included in this study. Appropriate surgical procedures will be applied to patients with pilonidal sinus disease who apply to Mersin University Hospital General Surgery Department. The method to be applied will be decided by discussing with the patient.
Data for this study will be collected between November 2024 and November 2025. During this period, data from patients who underwent surgery for pilonidal sinus disease at Mersin University Hospital General Surgery Clinic will be collected. Data will be collected from patients who apply for follow-up on the 1st day, 7th day, 6th month and 12th month after laser ablation or phenol treatment. Demographic characteristics, symptoms, clinical examination findings, surgical findings, postoperative VAS pain scores, wound complications, recurrence rates and return to daily life times will be examined. This data will be obtained through the retrospective review of medical records and confirmed by face-to-face interviews with patients who have attended the outpatient clinic, and then recorded in the data collection form.
Data collection will continue until at least 32 patients are reached in the phenolization and laser ablation groups. Once the target sample size is reached, new data collection from patients will be terminated and statistical analyses will be performed to compare prevalence between groups.
