The impact of experience on recurrence rates after biopsy punch excision for pilonidal disease

Is it beneficial to add laser ablation to curettage in the treatment of pilonidal sinus disease?

AIM

This study aimed to compare laser application with sinus curettage against only sinus curettage in the treatment of pilonidal sinus disease (PSD) in terms of postoperative complications, wound healing, and recurrence. Additionally, we aimed to investigate factors associated with wound healing and recurrence after PSD surgery.

PATIENTS AND METHODS

This study included patients diagnosed with PSD between February 2019, and September 2022. The patients were randomly assigned to either the laser + curettage (L/C; n = 40) group or the curettage-only (C; n = 40) group. The following data were collected: demographic and anthropometric information, smoking status, comorbidities, number of PSD-related orifices, complicated or uncomplicated disease, prior recurrence, postoperative findings, wound healing problems within 30 days postoperatively, and recurrence within 6 months postoperatively.

RESULTS

The L/C and C groups were similar in terms of age and sex distribution. The groups had similar results for postoperative pain, discharge, bleeding, wound healing problems at 30 days, and recurrence at 6 months. Multivariable logistic regression revealed that, high weight and higher orifice count were independently associated with wound healing problems. Additionally, high weight, higher orifice count and prior recurrence were independently associated with recurrence.

CONCLUSION

Combined curettage and laser therapy showed non-significant but broad benefits over curettage alone, but statistical significance was not achieved in any of the adverse findings, as well as wound healing and recurrence. Higher body weight and higher orifice count were associated with both poor wound healing and recurrence, while prior recurrence was another factor associated with recurrence at 6 months.

Pediatric pilonidal sinus disease: Recurrence rates of different age groups compared to adults

Background

Pilonidal sinus disease uncommon in pre-pubertal children. The preferred treatment for pediatric pilonidal sinus patients remains unclear. A growing body of evidence indicates that pediatric pilonidal sinus disease recurs earlier than in adults. We therefore aimed to investigate recurrence rates and the recurrence rates of different surgical approaches.

Methods

Some 1217 studies on pilonidal sinus disease, encompassing 134,663 patients were eligible. From them, 5807 pediatric patients were identified. Recurrence rates were compared between adults and children.

Results

Pediatric pilonidal sinus patients have a higher 5-year recurrence rate compared to adults (46 % vs. 11.5 %; p < 0.0001). The subgroup of individuals aged 16-18 years appears to experience recurrences 12 months earlier than those below the age of 16. 46.4 % of all pediatric recurrences occur within 5 years.

Conclusions

Pediatric pilonidal sinus disease seems to follow a different course in terms of recurrence rate compared to adults with a substantially increased probability of developing recurrent pilonidal sinus disease within the first five years after surgery. Due to the limited evidence base, especially in terms of the surgical approach, additional data is required to gain a more detailed insight into the matter and to improve surgical care for children and adolescents.

Surgical treatment of pilonidal disease - Short-term follow up results of minimally invasive pit-picking surgery versus radical excision without suturing: A prospective randomised trial

Background

In this study we compared the potential benefits of surgical treatments for chronic symptomatic pilonidal disease (PD) - minimally invasive pit-picking surgery and radical excision without wound suturing.

Materials and methods

A total of 100 adult patients with chronic symptomatic PD were enrolled in this study at the Kaunas Hospital of the Lithuanian University of Health Sciences. They were randomly divided into two groups: pit-picking surgery (n = 50) and radical excision with open healing (n = 50). Recurrent PD patients were not excluded. The comparison of the techniques was based on pain within the first postoperative week, failed surgery rates, and wound healing time. Additionally, pain levels at different time intervals following the treatment, analgesic consumption, and time off work, were assessed and compared.

Results

A total of 89 patients (89 %) were available for follow-up after 6 months. Pain levels the first postoperative week were significantly lower in the pit-picking group compared to the radical excision group, with median scores of 10.0 and 20.0, respectively (p = 0.002). The complete wound healing time was longer in the radical excision group (60 days) versus the pit-picking group (17 days), with a significant difference noted (p = 0.00). No significant difference was observed between the type of surgery and the rate of failed surgery, with 5 (11.9 %) cases in the pit-picking group and 4 (8.5 %) in the radical excision group.

Conclusion

Based on our short-term findings, minimally invasive pit-picking surgery is a better option regarding pain, wound healing time and failed surgery rate. In cases where this approach is not suitable, other alternatives should be contemplated, as radical surgery without wound suturing should not be employed as a treatment method for PD. Additionally, the relationship between PD and recurrence rates should be investigated further.

Surgical outcomes of minimally invasive trephine surgery for pilonidal sinus disease with and without laser therapy: a comparative study

BACKGROUND

Over the last decades, novel therapeutic options have emerged for the surgical treatment of pilonidal sinus disease (PSD). The aim of this study was to evaluate the outcomes of trephine/pit excision surgery with or without laser therapy in patients with PSD.

METHODS

A retrospective cohort study was conducted at a large tertiary medical center, including all adult patients with PNS who underwent trephine surgery with/without laser therapy between 2016 and 2021[AUTHORS TO INSERT MONTH]. Propensity score matching was used to address confounding factors, and the primary outcome was the 1-year recurrence rate.

RESULTS

The study included 221 patients with PSD, with a mean age of 23.73 years (87.7% male). In the unmatched cohort (130 trephine surgery alone, 91 trephine surgery + laser therapy), significant differences were observed in mean age (23 vs. 25 years; p < 0.01)[AUTHROS TO USE MEDIAN PLUS RANGE OR ADD SD] and surgeons' experience (p = 0.014). Propensity score matching was applied to overcome confounding factors, resulting in a matched cohort including 73 patients in each group. The addition of laser therapy demonstrated a significantly lower recurrence rate (8.2% vs. 32.9%; p < 0.001) compared to pit excision without laser therapy. Logistic regression analysis showed that the addition of laser was significantly associated with a lower risk for recurrence (OR 0.23; 95% CI 0.089-0.633; p < 0.01).

CONCLUSION

The incorporation of laser therapy along with trephine/pit excision surgery significantly reduces the recurrence rate in patients with PNS. Further prospective studies are needed to confirm our findings.

An international survey exploring the management of pilonidal disease

AIM

Pilonidal disease (PD) is a common debilitating condition frequently seen in surgical practice. Several available treatments carry different benefit/risk balances. The aim of this study was to snapshot the current management of PD across European countries.

METHOD

Members affiliated to the European Society of Coloproctology were invited to join the survey. An invitation was extended to others via social media. The predictive power of respondents' and hospitals' demographics on the change of therapeutic approach was explored.

RESULTS

Respondents (n = 452) were mostly men (77%), aged 26-60 years, practising in both academic and public hospitals and with fair distribution between colorectal (51%) and general (48%) surgeons. A total of 331 (73%) respondents recommended surgery at first presentation of the disease. Up to 80% of them recommended antibiotic therapy and 95% did not use any classification of PD. A primary closure technique was the preferred procedure (29%), followed by open technique (22%), flap creation (7%), sinusectomy (7%) and marsupialization (7%). Approximately 27% of subjects would choose the same surgical technique even after a failure. Almost half (46%) perform surgery as office based. A conservative approach was negatively associated with acutely presenting PD (p < 0.001). Respondents who were not considering tailored surgery based on patient presentation tended to change their approach in the case of a failed procedure.

CONCLUSION

With the caveat of a heterogeneous number of respondents across countries, the results of our snapshot survey may inform the development of future guidelines.

Five-year recurrence after endoscopic approach to pilonidal sinus disease: A multicentre experience

PURPOSE

The aim of this study was to evaluate the 5-year recurrence rate of pilonidal sinus disease (PSD) after endoscopic sinusectomy and identify risk factors for recurrence.

METHODS

All consecutive patients from September 2011 through December 2017 who underwent endoscopic sinusectomy at seven referral centres for pilonidal sinus treatment were retrospectively analysed from a prospectively maintained database.

RESULTS

Out of 290 patients (185 males versus 105 female, with a mean age of 25.5±6.9), 73 presented recurrence at 5-year follow-up with a recurrence rate of 25.2%. The number of pilonidal sinus with pits off the midline (p = 0.001) and the mean (SD) distance from the most lateral orifice to the midline (p = 0.001) were higher in the group of patients with recurrence at 5-year follow-up. Multivariate analysis demonstrated that the position of the pits off the midline (p = 0.001) and the distance of the most lateral orifice from the midline (p = 0.001) were independent risk factors for recurrence at 5-year follow-up. Receiver operating characteristic (ROC) curve analysis showed that the distance of lateral orifice from midline predicted an 82.2% possibility of recurrence at 5-year follow-up and Youden's test identified the best cut-off as 2 cm for this variable. Out of 195 cases with the most lateral orifice less than 2 cm from the midline, 13 presented recurrence at 5-year follow-up with a recurrence rate of 6.7%. Out of 95 cases with the most lateral orifice more than 2 cm from midline, 60 showed recurrence at 5-year follow-up with a recurrence rate of 63.2%.

CONCLUSIONS

This data may help guide which disease characteristics predict the optimal use of an endoscopic pilonidal sinus technique.
