Pilonidal Sinus Disease

Pilonidal sinus is a chronic infection of the sacrococcygeal skin that mainly affects young adults. Traditional surgery leaves large wounds requiring weeks of daily dressing changes away from home. Video-Assisted Ablation of Pilonidal Sinus (VAAPS) is a minimally invasive procedure that leaves only a 7-mm wound, but it requires daily saline flushing of the sinus tract and regular follow-up at the operating center. At Peking University People's Hospital, over 60% of VAAPS patients travel from other provinces and cannot return for standardized daily wound care. To address this, we developed a loose glove-edge seton technique: two rubber strips cut from surgical glove edges are loosely tied around the sinus openings during surgery to keep them patent, allowing normal dressing changes at home without flushing. The first strip is removed at 1 week and the second at 3 weeks postoperatively. This is a single-center prospective observational study of 50 out-of-town patients undergoing VAAPS with this seton technique. We will collect pain scores, time off work, wound healing time, complications, and recurrence over 3 years to assess whether self-care after VAAPS with loose seton is safe, effective, and feasible for patients who cannot return to the operating center for routine care.

This randomized controlled trial will evaluate the effect of Teach-Back-supported discharge education on self-care agency, pain intensity, and comfort levels in patients undergoing surgery for pilonidal sinus disease. A total of 68 participants will be randomly assigned in a 1:1 ratio to either the intervention group or the control group. The intervention group will receive discharge education using the Teach-Back method, while the control group will receive routine discharge education and standard care. Self-care agency, pain intensity, and comfort levels will be assessed at baseline and on the tenth day after discharge.

This single-center prospective randomized parallel-group trial compares laser ablation and crystallized phenol application in adults with primary uncomplicated sacrococcygeal pilonidal sinus disease. The primary objective is to compare postoperative day 1 pain intensity between the two treatment methods. Secondary objectives include complete epithelialization by day 30, time to complete epithelialization, postoperative day 7 pain, duration of analgesic use, time to return to daily activities and work, early local complications, and 6-month recurrence.

Pilonidal sinus disease is a common condition affecting young adults and is associated with pain, infection, and reduced quality of life. Various minimally invasive treatment options have been developed to reduce recurrence and improve recovery time. Among these methods, Silac (laser ablation) and phenol application are frequently used techniques. The aim of this prospective randomized controlled trial is to compare the effectiveness and safety of Silac and phenol treatments in patients with primary pilonidal sinus disease. Eligible patients will be randomly assigned to receive either Silac or phenol treatment. The primary outcome of the study is recurrence rate. Secondary outcomes include postoperative pain, healing time, time to return to work, patient satisfaction, and treatment cost. Patient recruitment is planned over a 6-month period, and each participant will be followed for 6 months after treatment. The total study duration will be 12 months. The results of this study are expected to provide evidence to guide the selection of minimally invasive treatment options for primary pilonidal sinus disease.

"Assessment of postoperative pain with conventional and tumescent local anesthesia in the laser treatment of pilonidal sinus." The aim of this study is to: examine the possible difference in postoperative pain between two local anesthesia procedures after laser treatment of pilonidal sinus disease on the first and second postoperative day, as well as one week after surgery. During the procedure, two well-established anesthesia techniques are used to make the surgical area painless. The first is local anesthesia, in which the anesthetic is injected into and under the skin. The second procedure is tumescent anesthesia. In this procedure, the anesthetic in diluted form is introduced into the subcutaneous tissue. Both procedures are used in surgery and are standard methods of local anesthesia.

This study compares two treatment approaches for pilonidal sinus disease: laser treatment alone versus laser treatment combined with phenol application. Pilonidal sinus is a common condition that affects young adults and can cause significant discomfort and time off work. Participants will be randomly assigned to receive either laser treatment only (Group A) or laser treatment plus phenol application (Group B). Both treatments are minimally invasive and performed under local anesthesia as day surgery procedures. The main goal is to determine if adding phenol to laser treatment speeds up the healing process (epithelialization) and improves patient outcomes. We will measure healing time, pain levels, return to daily activities, and quality of life over a 3-month follow-up period. This research may help develop more effective treatment protocols that reduce healing time and improve patient comfort for people with pilonidal sinus disease.
