LIMBERG FLAP FOR SACROCOCCYGEAL PILONIDAL SINUS: A SAFE AND PROMISING SURGERY

Introduction:Sacrococcygeal pilonidal sinus is a common disease of the adult age group, especially male population, causing significant morbidity from both disease and surgery done for the same. It is essentially a cleavage between the buttocks (i.e., natal cleft), and diagnosis is made by identifying the epithelialized follicle opening (i.e., sinus). The name PILONIDAL is taken from Latin meaning nest of hairs. The estimated incidence is 26 per 1,00,000 people1. It generally presents as a cyst, abscess, or sinus tract with or without discharge2. Men affected more often than women1, rare both before puberty and after the age of 40 years3. The etiology of the pilonidal sinus is a matter of controversy. Aims & Objectives:Literature study showed that Limberg flap reconstruction following rhomboid excision of the sinus area was superior to primary closure and other flap procedures and a safe and reliable method in sacrococcygeal pilonidal sinus disease with low complication and recurrence rates. Hence, this study was performed in our setup to evaluate the usefulness of Limberg flap procedure in sacrococcygeal pilonidal sinus, patient compliance, complications and long-term recurrence rates following the procedure. Materials & Methods:The study involves 22 patients, from May 2022 to September 2023. Most of the patients were males of those 4 were females. Average age was 24 years—the oldest was 29 years and the youngest was 15 years. Results:In this study 22 patients were included. Among them 18 were males and 4 were females. Mean age was 24 years (range 15–29 years). Of the 22 patients, 14 had primary disease, 6 had recurrent disease, and 2 came up after having previous incision and drainage for abscess. All patients came with pilonidal sinus, from May 2022, were assessed for its severity and investigated, and then they underwent Limberg flap surgery under spinal anesthesia. Discussion:Sacrococcygeal pilonidal sinus is blind epithelial tract situated in the skin of the natal cleft, close to anal verge, generally containing hair. The etiology is matter of debate initially congenital origin was thought of which is now given up. Main causes for the formation of this sinus are hirsutism, sweating in the area, repeated maceration due to trauma, leading to breakage of the skin barrier, attracting hair inside which initiates a foreign body reaction leading to infection with abscess or sinus formation. Conclusion:Sacrococcygeal pilonidal sinus is headache to both the patient and the treating surgeon because of its repeated infection, persistent pain with discharge, and high recurrence rates with regular procedures.
