The Surgical Management of Pilonidal Disease is Uncertain Because of High Recurrence Rates

The application of ERAS in pilonidal sinus: comparison of postoperative recovery between primary suture and Limberg flap procedure in a multicenter prospective randomized trial

Purpose

We evaluated the clinical effect of utilizing a Limberg rhomboid flap graft in conjunction with Enhanced Recovery After Surgery (ERAS) protocols for the management of pilonidal sinus in the sacrococcygeal region to demonstrate the feasibility of applying ERAS to the treatment of pilonidal sinus.

Methods

Between January 2010 and August 2018, prospective data analysis was undertaken on 109 patients who received surgical treatment for pilonidal sinus in the sacrococcygeal region at the Department of Colorectal and Anal Surgery, Jingzhou Hospital affiliated to Yangtze University, and Taizhou Affiliated Hospital of Nanjing University of Chinese Medicine. The patients were randomly separated into two groups based onoperation technique: the control group (pilonidal sinus resection with primary suture) and the observation group (pilonidal sinus resection with Limberg flap graft). Some patients in the above two groups received ERAS after surgery, which included early feeding and early ambulation, etc. Therefore, we further subdivided each group into group A (without ERAS) and group B (with ERAS) according to whether they received ERAS. Comparative analysis was conducted to assess differences in pertinent data before and after surgery across the respective groups.

Results

The length of postoperative hospitalization was shorter and wound dehiscence was more common in control group B than in control group A [(9.00 ± 1.20) vs. (11.07 ± 1.78), 26.7% (8/30) vs. 7.1% (2/28), P < 0.05]. Observation group B exhibited significantly shorter wound recovery periods and postoperative hospital stays compared to observation group A [(8.08 ± 1.20) vs. (9.16 ± 2.21), (26.23 ± 3.97) vs. (29.08 ± 4.74), P < 0.05]. The hospitalization duration and wound healing time in observation group B were notably shorter than those observed in control group B [(8.08 ± 1.20) vs. (9.00 ± 1.20), [26.23 ± 3.97 vs. (43.67 ± 7.26), P < 0.05], but the operation time was longer and scar acceptance was lower [(78.85 ± 10.16) vs. (43.30 ± 6.06), (4.00 ± 0.69) vs. (7.53 ± 0.86), P < 0.05]. The VAS score, infection rate, wound dehiscence rate, subcutaneous hematoma rate and 5-year recurrence rate in observation group B were lower than those in control group B [(5.00 ± 1.39) vs. (7.13 ± 0.78), 3.8% (1/26) vs. 23.3% (7/30), 3.8% (1/26) vs. 26.7% (8/30), 3.8% (1/26) vs. 26.7%(8/30), 7.7% (2/26) vs. 30.0% (9/30), P < 0.05], but the rate of flap ischemia or necrosis was higher [15.4% (4/26) vs. 0(0/30), P < 0.05].

Conclusion

The combination of ERAS with pilonidal sinus resection using Limberg flap graft demonstrated a reduction in infection rates, wound dehiscence, subcutaneous hematoma occurrence, and recurrence rates, along with alleviation of postoperative pain and acceleration of healing time. Comparatively, this approach offers superior advantages over pilonidal sinus resection with primary suture in the management of sacrococcygeal pilonidal sinus.

Pilonidal sinus: an overview of historical and current management modalities

Pilonidal disease is a common condition that commonly affects the younger adult population and is often seen in both the general practice and the hospital setting. Multiple treatment methods have gained and lost popularity over the last several decades, but more recent intervention principles show promising results. This article details the different methods of managing acute and chronic pilonidal disease ranging from treatments in the primary care setting to those in hospital theatres, with special attention to newer modalities of minimally invasive interventions. As a chronic illness that often affects those of working age, pilonidal disease can confer significant morbidity especially, but not limited to, a substantial amount of time off work. Treatment of chronic disease in particular, has evolved from midline techniques to off-midline techniques, with more recent developments offering promising solutions to reduce acute flare ups and hasten recovery time.

Surgical Practice Parameters for the Definitive Management of Sacrococcygeal Pilonidal Sinus Disease: Surgeons' Perspective

Background Sacrococcygeal pilonidal sinus disease (SPD) is a common general surgical condition encountered in practice and predominantly affects young males. Surgical practice parameters for the management of SPD are variable. This study aimed to review current surgical practice parameters for SPD management in Western Australia. Methodology This study conducted a de-identified 30-item multiple-response ranking, dichotomous, quantitative, and qualitative survey of self-reported surgeon practice preferences and outcomes. The survey was sent to 115 Royal Australian College of Surgeons - Western Australia general/colorectal surgical fellows. Data were analyzed using SPSS version 27 (IBM Corp., Armonk, NY, USA). Results The survey response rate was 66% (N = 77). The cohort comprised mostly senior collegiate (n = 50, 74.6%), and most were low-volume practitioners (n = 49, 73.1%). For local disease control, most surgeons perform a complete wide local excision (n = 63, 94%). The preferred wound closure method was an off-midline primary closure (n = 47, 70.1%). Self-reported SPD recurrence, wound infection, and wound dehiscence rates were 10%, 10%, and 15%, respectively. The three high-ranked closure techniques were the Karydakis flap, Limberg's flap (LF), and Z-Plasty flap. Each surgeon's median annual SPD procedures were 10 (interquartile range = 15). The surgeons could utilize their preferred SPD closure technique (mean = 83.5%, standard deviation = ±15.6). Univariate analysis showed significant associations between years of experience and SPD flap techniques utilized, with senior surgeons significantly less likely to use either the LF (p = 0.009) or the Bascom procedure (BP) (p = 0.034). Instead, there was a preference for using healing by secondary-intention technique (SIT) compared to younger fellows (p = 0.017). A significant negative correlation existed between practice volume and SPD flap technique utilization, with low-volume surgeons less likely to prefer the gluteal fascia-cutaneous rotational flap (p = 0.049) or the BP (p = 0.010). However, low-volume practice surgeons were significantly more likely to use SITs (p = 0.023). The three most important patient factors in choosing SPD techniques were comorbidities, likely patient compliance, and attitude toward the disease. Meanwhile, factors influencing local conditions included the proximity of the disease to the anus, the number and location of pits and sinuses, and previous definitive SPD surgery. Key informants for technique preference were perceived low recurrence rate, familiarity, and overall good patient outcomes. Conclusions Surgical practice parameters for managing SPD remain highly variable. Most surgeons perform midline excision with off-midline primary closure as the gold standard. There is a clear and present need for clear, concise, and yet comprehensive guidelines on managing this chronic and often disabling condition to ensure the delivery of consistent, evidence-based care.

A mapping review of sacrococcygeal pilonidal sinus disease

BACKGROUND

Pilonidal sinus is a hole in the natal cleft which may cause severe pain and become infected. The evidence base for management of pilonidal sinus is said to be poor quality, poorly focused and rapidly proliferating. We undertook a systematic mapping review to provide a broad overview of the field and support the identification of research priorities.

METHODS

We searched MEDLINE, CINAHL, and EMBASE from inception to 22nd Nov 2020 for primary research studies focused on the management of pilonidal sinus. We extracted data on study design and categorised studies under five major headings ('non-surgical treatment', 'surgical treatment', 'aftercare' and 'other'), producing frequency counts for different study designs. Gaps in research were identified from published systematic reviews and tabulated.

RESULTS

We identified 983 eligible studies, of which 36 were systematic reviews and/or meta-analyses; 121 were randomised controlled trials), and 826 observational studies of various design. The majority of studies evaluated surgical techniques (n = 665), or adjuvant medical interventions (n = 98). The literature on wound care has developed most recently, and the evidence base includes 30% randomised controlled trials. Gaps analysis highlighted comparison of surgical techniques including flaps, laser depilation, and wound care interventions as potential areas for randomised controlled trials.

CONCLUSIONS

This mapping review summarises eight decades of research on the management of pilonidal sinus. Further research is needed to identify front-running interventions, understand variation in practice and patient values, and to prioritise future research.

The Benefits of Colorectal Surgery Surveys in Australia and New Zealand

PURPOSE

Pertaining to the Colorectal Surgery Society of Australia and New Zealand (CSSANZ) Executive and Research Support Committee, this study aimed to assess the usefulness and outcomes of surveys sent out by the society to its members.

METHODS

From 2009 to 2017, CSSANZ members received 38 surveys, most of which were distributed from within the society, and a few of which originated from other affiliated groups. Surveys were categorised by type, topics, times required for completion, delivery method, response rates, and advancement to publication.

RESULTS

Of 38 surveys, 20 (53%) were published and 18 remain unpublished. Four surveys were distributed annually on average, with 2.2 published annually on average, with a mean impact factor of 2.41 ± 1.55. Mean time to publication was 31 ± 17 months. Surveys contributed to 13 publications (34%). The most common survey topics were rectal cancer decisionmaking, in 6 publications (16%), preoperative assessment of colorectal patients, in 5 publications (13%), and anal physiology: continence and defaecation, in 4 publications (11%). Publication of surveys was not related to the number of surveys distributed per year, the number of questions per survey, or the time required by respondents to complete the surveys.

CONCLUSION

Most of the CSSANZ-distributed surveys resulted in publications, and one third of the surveys contributed to higher degrees obtained by investigators. These surveys aid research into areas that are otherwise difficult to assess, often indicating areas for future research.

The Correlation Between Delayed Surgical Therapy After the Diagnosis of Pilonidal Sinus Disease and Relapse, Labor Loss, and Costs

Introduction There has been no detailed study of the relationship between recurrence and symptom duration in pilonidal sinus disease. The aim of this study was to explore the correlation between delayed surgical therapy after symptoms appear in sacrococcygeal pilonidal sinus disease (SPSD) and relapse, labor loss and costs. Methods Patients diagnosed with SPSD were split into two groups according to symptom duration before surgery: 30 days or less (G1) and more than 30 days (G2). Patients included those who underwent Limberg flap reconstruction (LFR) for primary SPSD. The length of hospitalization during surgery, postoperative follow-up period, and, if any, relapse periods were obtained from patients' files. Of the patients with incomplete information, only those whose information was confirmed by phone were also covered by the study. Results G1 included 153 patients, including 37 (24.18%) females and 116 (75.82%) males. The median age in G1 was 22 years and the mean age was 23.08±8.72 years. G2 included 214 patients, including 51 (23.83%) females and 163 (76.17%) males. The median age in G2 was 22 years and the mean age was 22.64±9.06 years. The mean lengths of hospitalization in G1 and G2 were 2.14±0.86 and 2.98±1.04 days, respectively, and the difference between them was significant (p<0.03). The follow-up periods in G1 and G2 were 61.52±29.84 (12-108) and 64.0±31.24 (12-113) months, respectively. Relapse occurred in nine patients (5.8%) in G1 and 19 patients (8.8%) in G2, and the difference between them was significant (p<0.02). The mean relapse period was 3.44±6.01 and 11.23±7.62 months in G1 and G2, respectively, and the difference between them was significant (p<0.04). Conclusion Delayed surgery should be avoided to minimize the costs and the probability of relapse in SPSD.

Analysis of the Relapse Rates of the Primary Closure and Limberg Flap Techniques in Pilonidal Sinus Surgery

Background This study aimed to assess the relapse rates at the long-term follow-up of the Limberg flap repair (LFR) and primary closure (PC) methods in the surgical treatment of pilonidal sinus disease (PSD). Methods The records of primary PSDs who underwent LFR and PC due to PSD were retrospectively examined. The study included patients whose surgical intervention was performed at least two years ago. The patients were contacted by phone to obtain information. They were asked whether they had a relapse or not, and their answers were recorded. The recording and analysis were ensured using the SPSS statistical program (IBM Corp, Armonk, NY, US). The groups were compared using the chi-square test. p˂0.05 was considered significant. Results The patients' mean age was 23.68 ± 8.21 years, and their median age was 22 years. The overall follow-up period was 4.38 ± 2.12 years. LFR-treated patients numbered 292; 38 (13.01%) females and 254 (86.99%) males. Of the LFR-treated patients, 23 (7.87%) had a relapse, including five (13.15%) females and 18 (7.08%) males (p˂0.03). PC-treated patients numbered 184; 58 (31.52%) females and 126 (68.48%) males. Of PC-treated patients, 39 (21.19%) had a relapse, including 15 (25.86%) females and 24 (19.04%) males (p˂0.04). The relapse was more than three times higher in PC when compared to LFR (p˂0.01). Conclusion LFR clearly takes precedence over PC. In both methods, the relapse rate is higher in females. We believe that this is due to our tendency to be more limited in resection in women.
