ABSTRACT

Objective: The study aims to evaluate and compare the outcomes of two surgical techniques, the limberg flap and Bascom cleft lift, used in the treatment of sacrococcygeal pilonidal sinus. Key metrics for comparison include postoperative complications, hospital stay duration, and surgery duration.

Methods: This was a prospective study conducted at ESIC Hospital, Jaipur, involving 100 patients diagnosed with sacrococcygeal pilonidal sinus requiring surgical intervention. Patients were divided into two groups: Group I underwent the Bascom cleft lift procedure (n=40), and Group II underwent the limberg flap technique (n=60). Both groups were evaluated over a period of one and a half years with preoperative assessments and postoperative follow-ups for complications, duration of surgery, and length of hospital stay.

Results: The study included 40 patients in the Bascom group (42.5% male, 57.5% female) and 60 in the limberg group (55% male, 45% female). The average surgery duration was significantly shorter for the Bascom procedure (36.73±6.52 min) compared to the limberg flap (74.58±10.10 min). Postoperative complications were higher in the limberg flap group. The Bascom cleft lift patients experienced shorter hospital stays and fewer postoperative issues, including lower rates of discharge and infection.

Conclusion: The Bascom cleft lift procedure appears to be superior to the limberg flap in terms of shorter operative time, fewer complications, and quicker recovery. These findings suggest that the Bascom cleft lift could be a more efficient and safer option for the surgical treatment of pilonidal sinus, promoting faster patient recovery with fewer postoperative complications.

INTRODUCTION

The term "pilonidal sinus" describes a condition set up in the natal cleft overlying the coccyx, consisting of one or more, usually non-infected, midline openings, which communicate with a fibrous track lined by granulation tissue and containing hair lying loosely within the lumen. It has been referred to as "jeep disease". Herbert Mayo defined the disease for the first time in 1883, and Hodge used the name "pilonidal" for the first time in 1880, derived from latin words for hair (pilus) and nest (nidus) [1].

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 split) and the epithelialized follicle opening (i. e. sinus) is identified, resulting in a diagnosis. The name pilonidal is taken from the latin meaning “nest of hairs” [2]. Factors associated with the recurrent pilonidal disease include hair, deep midline gluteal clefts, un-debrided devitalized tissue and suture line tension [3]. It generally presents as a cyst, abscess, or sinus tracts with or without discharge. Men affected more often than women [4], rare both before puberty and after the age of 40 years. Rarely may it present in the fourth decade [5].

The estimated incidence is 26 per 100000 people, affecting men twice as often as women [6]. It is more common in people aged 15-30 y after puberty due to the effect of sex hormones on pilosebaceous glands and change in healthy body hair growth [7].

Local trauma, poor hygiene, excessive hairiness, and the presence of a deep natal cleft are widely accepted views as causes [8]. Karydakis proposed three main factors causing the disease, namely the high quantity of hair, extreme force and vulnerability to infection [9].

In clinical practice, Sacrococcygeal pilonidal sinus is regularly diagnosed and treated as it causes the reduction in the quality of life, serious labor loss and increased hospital costs. There are two main treatment methods: minimally invasive approaches (fibrin glue, phenol, laser application) and invasive methods (excision and simple closure, rotation flap, limberg flap and Bascom cleft lift) [10-12].

In 1946, limberg designed a rhomboid flap for sacrococcygeal pilonidal sinus. He described a technique for closing a 60° rhombus-shaped defect using a transposition flap. It was easy to perform the flap with sutures away from the midline giving rise to a tensionless flap of unscarred skin in the midline, which helps in good hygiene maintenance, reducing sweating maceration, erosions and scar formation [13].

Various methods have been defined for off-midline surgical treatment. Among them, the most commonly used is rhomboid excision with the limberg flap. With this technique of flattening the natal cleft, a tension-free repair is made using a wide, well-vascularized flap. It comprises one of the best treatment methods, with a 0–16% rate of surgical area-related complications and recurrence rate of 0–5% [14].

The other off-midline technique is the cleft lift procedure described by Bascom. This technique was originally developed to deal with operations that had failed to heal or where symptoms continued to recur. Today, it is being carried out more and more as a first-time procedure [15, 16].

Aims and objectives

MATERIALS AND METHODS

The study was conducted in the Department of Surgery, ESIC Hospital, Jaipur.

Inclusion criteria

Exclusion criteria

The inclusion and exclusion criteria were followed and all the patients underwent routine investigations and then preanaesthetic fitness.

Group I (n = 40): Patients underwent Bascom cleft lift technique

Group II (n = 60): Patients underwent Pilonidal surgery by limberg flap technique

They were evaluated for the study period of one and half year and all the data was collected and the results were statistically analysed.

Methods

Bascom and Bascom performed the Bascom cleft lift procedure (group I) as described [17, 18]. The buttocks were pushed together, and the outer line of contact was marked. Beginning at 2 cm lateral of the midline, an incision was made 1–2 mm on the side of the sinus opening and curving around the anus. The skin from one side of the natal cleft was then elevated and excised. The skin on the opposite side of the cleft was undermined to a distance required to allow the primary closure of the defect away from the midline without tension. The abscess cavity was curetted or scrubbed with gauze. The fat tissue of the natal cleft was approximated using absorbable (2/0 polyglactin) sutures. The wound was closed with 3-0 polypropylene interrupted mattress sutures.

Mentes et al. described a technique for performing an excision and limberg flap transposition (group II) [19]. The area to be excised was mapped on the skin in a rhomboid form, and the flap was designed. The skin incision was deepened to the postsacral fascia. The flap was fully mobilized and transposed medially to fill the defect without tension. The wound was closed in two layers: the subcutaneous tissue with absorbable (2/0 polyglactin) sutures and the skin with non-absorbable (3/0 polypropylene) interrupted mattress sutures.

RESULTS

The study involved a total of 100 patients diagnosed with sacrococcygeal pilonidal sinus, divided into two groups based on the surgical intervention received. Group I consisted of 40 patients who underwent the Bascom cleft lift procedure, and Group II included 60 patients treated with the limberg flap technique.

Demographic distribution

Surgical and postoperative data

The average duration was significantly shorter for the Bascom procedure (36.73±6.52 min) compared to the limberg flap (74.58±10.10 min).

Patients undergoing the Bascom procedure had shorter hospital stays, with most being discharged within 1-2 d post-surgery, whereas patients in the limberg group typically stayed 2-3 d.

Bascom group: 8 patients (20%) reported pus discharge, 5 (12.5%) had blood discharge, and the majority (67.5%) had no discharge postoperatively. Only 1 case (2.5%) reported wound infection.

Limberg group: 9 patients (15%) reported pus discharge, 7 (11.67%) had blood discharge, and a higher proportion (73.33%) had no discharge. Wound infections were slightly lower at 1.67%, but recurrence was observed in 6.7% of cases.

Recurrence and other complications

The recurrence rate was lower in the Bascom group (5%) compared to the limberg group (6.7%). Other complications included minor infections and wound dehiscence, both of which were more common in the limberg group.

The results indicate that the Bascom cleft lift procedure not only reduces the surgery duration but also minimizes postoperative complications and expedites patient recovery compared to the limberg flap technique.

DISCUSSION

The present observational study was conducted at the department of surgery, which included patients diagnosed with pilonidal sinus between the age of 18 to 48 y. The study aimed to assess the surgical outcome between the Bascom flap and the limberg flap. Total of 100 patients were included in the present study after obtaining informed consent, with Group A (n=40) patients undergoing Bascom flap procedure and Group B (n=60) patients undergoing limberg flap procedure.

In the present study, the mean age of patients was found to be 28.85+8.02 y of age in group A and in group B 31.42+10.26 y, with no significant difference in the mean age between the two groups. The mean age among patients in study by Basavaraju et al. [20] was found to be 24.4 y of age. On assessment of the gender, male preponderance with 22 (73.33%) and 08 (26.66%) females were seen. Male to female ratio was found to be 2.75:1. There was no significant difference in distribution of patients between the groups.

In present study, post-operative complications found to be significantly higher in the limberg Flap method as compared to the Bascom flap method. The mean operative time was found to be 36.73+6.52 min and 74.58+10.10 min for the Bascom flap and the limberg flap method, respectively. The results suggest that Bascom flap surgery is shorter than the duration of limberg Flap surgery. In concordance to present study, Wadhawan G et al. [21] documented the mean operative time for the limberg group (75 min).

In the present study, the post-operative complication like wound infection was found in 1 (2.5%) in Bascom and in limberg flap wound infection 1 (1.67%) and recurrence was found in 2 (5%) in Bascom flap and 1 (6.7%) in limberg flap. In the study by Jeyalaksmi T et al. [22] wound infection was detected in Nil patients from the limberg Flap group.

CONCLUSION

The main goals of the pilonidal treatment are maintaining good personal hygiene and regular epilation of the local area and a definitive good surgical procedure. Hence the flap techniques-Limberg flap is the most effective surgery to treat pilonidal disease.

The limberg flap treatment demonstrated a quicker operational time and decreased blood loss. The limberg flap treatment is the better choice for patients when compared to the Bascom flap procedure.
