Background: The destruction of the pilonidal sinus with a radial laser probe has been suggested as a safe procedure with good results and low morbidity. Nevertheless the drawbacks of this technique are: a blind technique, if the sinus has some ramifications, or e non-linear development we cannot be sure for their destruction.

Methods: 17: patients (12 men, 5 women) were operated with US guided laser destruction- US guided Si. Read More

General Surgery Unit, San Giovanni Decollato Andosilla Hospital, Civita Castellana, Viterbo, Italy.

Background: Minimally invasive techniques for treating pilonidal disease are safe and effective alternatives to conventional surgery, with improved recovery time, cosmetic results, and pain control. The aim of this study was to evaluate the 5-year surgical outcomes of a single-center case series treated with endoscopic pilonidal sinus treatment (EPSiT).

Methods: We conducted a retrospective single-center analysis of all patients treated with EPSiT, by a single surgical team, from March 2015 to December 2019, for primary or recurrent pilonidal disease. Read More

Background: Gender-specific risk factors have been suggested to promote a fourfold higher incidence of pilonidal sinus disease (PSD) in male as compared to female patients. However, in recent decades there has been an apparent shift towards an increasing prevalence of PSD in women, as body weight and other risk factors influence the disease. We aimed at determining whether PSD prevalence actually changed in men and women over time. Read More

Hidradenitis suppurativa (HS) is a chronic autoinflammatory skin disorder characterized by recurrent painful nodules, abscesses, sinus tracts, and scarring on intertriginous body areas. Perifolliculitis capitis abscedens et suffodiens (PCAS) is a component of the follicular occlusion tetrad along with HS, acne conglobata, and pilonidal cyst. We report a case of HS with PCAS that was successfully treated with adalimumab, a human anti-tumor necrosis factor (TNF) monoclonal antibody. Read More

Aim: There is no standard method for the management of sacrococcygeal pilonidal disease (SPND); however, surgery remains the gold standard treatment. Wide surgical excision of the sinus is the traditional surgical treatment of SPND, yet it is associated with extended healing time and delayed recovery. This study aimed to compare the outcomes of sinus laser therapy (SiLaT) and sinus lay open in the management of SPND. Read More

Pilonidal sinus disease (PSD) is a chronic problem often occurs in healthy hirsute men, however, women may also be affected. A range of conservative techniques to surgical flaps have been used to treat this condition. Currently, midline primary closure (MPC) is considered the standard of therapy; however, no statistically significant difference has been noted between primary versus secondary (Karydakis flap or Limberg flap) closure.

Introduction: Fistula Laser Closure (FiLAC) is a method that was originally applied in the treatment of perianal fistulas. Because of promising results, diode lasers were later on used to treat pilonidal sinus disease in a method called sinus Laser Closure (SiLaC). The aim of this study is to compare between SiLaC and Limberg flap in management of pilonidal disease. Read More

Minimally invasive surgical (MIS) techniques for pilonidal sinus disease (PNS) have gained popularity in recent years, due to faster recovery and lower complication rate compared with conventional methods. Our aim was to assess recurrence rate following MIS Trephine procedure for PNS and to identify possible risk factors for recurrence. A prospective cohort, including patients who underwent PNS Excision by Trephine MIS Procedure over 5 years in a large tertiary medical center was established. Read More

Pilonidal sinus (PS) disease frequently occurs in adolescents and young adults, and in many cases involves wide excision or local flaps as treatment. These treatments are associated with a significant recurrence rate, a long healing time, and thus absence from school or work. The hybrid technique, which is a combination of side-swing plasty with negative-pressure wound therapy (NPWT) may improve these outcomes. Read More

(1) Background: Several techniques for the treatment of pilonidal sinus disease (PSD) are in vogue, though none have emerged as the gold standard. Laying open (deroofing) and curettage under local anesthesia is one of the most straightforward procedures to treat PSD. In this study, the long-term follow-up in a large series was analyzed.

Objective: The most important cause of post-treatment recurrence in the pilonidal sinus is the re-entry of hair into the skin. The study aimed to investigate the effect of hair removal and its duration on the prevention of recurrences after crystallized phenol treatment.

Subject And Methods: The patients with pilonidal sinus disease who were treated with crystallized phenol treatment were evaluated. Read More

Pilonidal sinus (PNS) is a clinically diagnosed condition caused by hair entrapment underneath the skin leading to a granulomatous reaction and the formation of a tract. PNS is commonly found in the sacrococcygeal area (natal cleft). However, this is a rare case presentation of a male patient with PNS located at the back of his neck region as there were only four similar conditions reported in the literature review. Read More

Department of Visceral Surgery, Geneva University Hospitals and Medical School, Rue Gabrielle-Perret-Gentil 4, 121, Geneva 14, Switzerland.

Background: Surgical wound infection contributes to prolonged recovery time after pilonidal sinus excision. As a standard procedure after surgery, we recommend our patients to perform water irrigations in the intergluteal cleft 4 to 6 times a day during the post-operative period. Our hypothesis is that this should reduce healing time and complication rates. Read More
