SiLaT: A paradigm shift in the treatment of pilonidal disease?

BACKGROUND: Pilonidal disease (PD) is a common condition for which the global incidence is increasing. Surgery is the currently preferred approach to treatment but there is a growing interest in new minimally invasive techniques, such as sinus laser therapy (SiLaT). AIM: Our primary objective was to assess the efficacy of SiLaT for the treatment of pilonidal disease. The secondary objectives were to evaluate morbidity and patient satisfaction and identify predictive factors of success. METHODS: All adult patients, who underwent SiLaT in our department for a primary or recurrent pilonidal sinus from June 1, 2018, to December 31, 2020, were included in the study. Healing was defined as the closure of cutaneous orifices and the absence of seepage or abscesses. RESULTS: In total, 111 consecutive patients, for whom the male/female sex ratio was 2.1 and the mean age 28.8 (± 9.4) years, were included in this study. Eighteen (16.2%) patients had already undergone prior surgery for PD. The mean follow-up was 339.2 (± 221.4) days. A healing rate of 78.4% was observed, with a median time to healing of 20.0 days (15.0-30.0). The median time to return to usual activities was three days (1-7). The only postoperative complication was bleeding, which occurred for two patients (1.8%). Eighty-two patients (88.2%) reported being "very satisfied" with the treatment. Multivariate analysis showed no predictive factors for healing among the studied variables. CONCLUSION: SiLaT is an efficient and safe procedure for the treatment of PD, with a high level of patient satisfaction. It will now be necessary to position it within the therapeutic algorithm.

[Anal fistulas: Sparing the sphincter]. / Fistules anales, épargner le sphincter.

ANAL FISTULAS: SPARING THE SPHINCTER. Fistulotomy is the most used treatment for anal fistula. It is very effective with a cure rate of over 95% but carries a risk of incontinence. This has led to the development of various sphincter sparing techniques. The injection of biological glue or paste and the insertion of a plug have disappointing results and are expensive. The rectal advancement flap is still practised because of its cure rate of around 75% but it may result in some incontinence. Intersphincteric ligation of the fistula track and laser treatment are widely practised in France with cure rates between 60 and 70%. Video-assisted anal fistula treatment as well as injections of adipose tissue, stromal vascular fraction, platelet-enriched plasma and/or mesenchymal stem cells are emerging techniques for which even better results are expected.

FISTULES ANALES, ÉPARGNER LE SPHINCTER. La fistulotomie est le traitement le plus souvent utilisé dans la fistule anale. Elle est très efficace, avec un taux de guérison supérieur à 95 %, mais expose à un risque d'incontinence. Cela a conduit au développement de diverses techniques d'épargne sphinctérienne. L'injection de colle ou de pâte biologique ainsi que la mise en place d'un plug ont des résultats finalement décevants et un coût élevé. Le lambeau rectal d'avancement est encore pratiqué en raison de son taux de guérison aux alentours de 75 %, mais il peut se solder par quelques troubles séquellaires de la continence. La ligature intersphinctérienne du trajet fistuleux et le laser sont largement pratiqués en France, avec des taux de guérison oscillant entre 60 et 70 %. Le traitement vidéo-assisté du trajet fistuleux ainsi que les injections périfistuleuses de tissu adipeux, de fraction vasculaire stromale, de plasma enrichi en plaquettes et/ou de cellules souches mésenchymateuses sont des techniques émergentes dont on espère de meilleurs résultats encore.

Long-term Outcome of a Fissurectomy: A Prospective Single-Arm Study of 50 Operations out of 349 Initial Patients.

PURPOSE: The surgical standard of care for patients with chronic anal fissure is still disputed. We aimed to assess the natural course of idiopathic anal fissure and the long-term outcome of a fissurectomy as a surgical treatment. METHODS: All consecutive patients referred to a single expert practitioner in a tertiary centre were primarily included. A fissurectomy was proposed in cases of refractory symptoms after 4 to 6 weeks of standard medical management. Only patients with idiopathic and noninfected anal fissures were included in this second subsample to undergo surgery. Conventional postoperative management was prescribed for all patients who had undergone surgery. The main outcome measures were the success rate (defined as a combination of wound healing and relief of pain) and postoperative anal continence. RESULTS: Three hundred forty-nine patients were primarily recruited. Fifty patients finally underwent surgery for an idiopathic and noninfected fissure. Among them, 47 (94%) were cured at the end of primary follow-up, and 44 of the 47 (93.6%) could be confirmed as being sustainably cured in the longer-term follow-up. The mean time of complete healing was 10.3 weeks (range, 5.7-36.4 weeks). All patients were free of pain at weeks 42. The continence score after surgery was not statistically different from the preoperative score. CONCLUSION: A fissurectomy for the treatment of patients with an idiopathic noninfected fissure is associated with rapid pain relief and a high success rate even though complete healing may often be delayed. Moreover, it appears to have no adverse effect on continence.

Elaboration and validation of Crohn's disease anoperineal lesions consensual definitions.

AIM: To establish consensual definitions of anoperineal lesions of Crohn's (APLOC) disease and assess interobserver agreement on their diagnosis between experts. METHODS: A database of digitally recorded pictures of APLOC was examined by a coordinating group who selected two series of 20 pictures illustrating the various aspects of APLOC. A reading group comprised: eight experts from the Société Nationale Française de Colo Proctologie group of study and research in proctology and one academic dermatologist. All members of the coordinating and reading groups participated in dedicated meetings. The coordinating group initially conducted a literature review to analyse verbatim descriptions used to evaluate APLOC. The study included two phases: establishment of consensual definitions using a formal consensus method and later assessment of interobserver agreement on the diagnosis of APLOC using photos of APLOC, a standardised questionnaire and Fleiss's kappa test or descriptive statistics. RESULTS: Terms used in literature to evaluate visible APLOC did not include precise definitions or reference to definitions. Most of the expert reports on the first set of photos agreed with the main diagnosis but their verbatim reporting contained substantial variation. The definitions of ulceration (entity, depth, extension), anal skin tags (entity, inflammatory activity, ulcerated aspect), fistula (complexity, quality of drainage, inflammatory activity of external openings), perianal skin lesions (abscess, papules, edema, erythema) and anoperineal scars were validated. For fistulae, they decided to follow the American Gastroenterology Association's guidelines definitions. The diagnosis of ulceration (κ = 0.70), fistulae (κ = 0.75), inflammatory activity of external fistula openings (86.6% agreement), abscesses (84.6% agreement) and erythema (100% agreement) achieved a substantial degree of interobserver reproducibility. CONCLUSION: This study constructed consensual definitions of APLOC and their characteristics and showed that experts have a fair level of interobserver agreement when using most of the definitions.

Is routine pathologic evaluation of hemorrhoidectomy specimens necessary?

AIM: To confirm that systematic histological study of hemorrhoidectomy specimens is useless, as is proposed by the French Society of Coloproctology (Société Nationale Française de Colo-Proctologie) under the sponsorship of the French National Health Accreditation and Evaluation Agency (Agence Nationale d'Accréditation et d'Evaluation en Santé). METHODS: Retrospective histological analysis of hemorrhoidectomy specimens obtained in a coloproctology unit between January 1, 1985 and December 31, 2001. RESULTS: We found 56 histological abnormalities (0.69%) among 8153 hemorrhoidectomy specimens considered normal at gross examination, with three cases of intraepithelial neoplasia of the anal canal (0.04%) and four cases of severe dysplasia (0.05%). Specimens associated with anal fissure (N = 906) or suppuration (N = 610) did not display more histological lesions. For all patients, the initial surgical resection prevented recurrence. CONCLUSION: Routine pathological evaluation of hemorrhoidectomy specimens is not useful and is expensive. All operating procedures in proctology should reflect this attitude. It is nevertheless advisable to select for gross and microscopic evaluation any suspicious areas noticed at the preoperative examination or during the procedure.

Lessons from the first 70 patients operated by doppler-guided haemorrhoidal artery ligation with mucopexy in a French team specialising in surgical proctology / Lições dos primeiros 70 pacientes operados por ligadura de artéria hemorroidária guiada por doppler com mucopexia por uma equipe francesa especializada em proctologia cirúrgica

ABSTRACT Background: Doppler-guided haemorrhoidal artery ligation with mucopexy is a minimal-invasive surgical technique. It is both effective and less painful than conventional haemorrhoidectomy. Methods: We gathered records on all patients operated on between November 2012 and June 2014. Pre- and postoperative scores were calculated during consultation and then by phone. Unsuccessful surgical treatment was defined by persistent haemorrhoid symptoms within three months following the procedure and relapse defined by recurrent symptoms after the third postoperative month. Results: During the period analysed, 70 patients underwent consecutive surgical procedures for haemorrhoid prolapse (52%), bleeding (29%), or both (17%). Hospitalisation was outpatient or overnight for 87% of patients. There were no complications in 92.7% of cases. The average period away from work was 11 days (± 6.5). The time between the procedure and last postoperative consultation, followed by telephone contact, was respectively 2.7 months (± 5.8) and 16.5 months (± 4.9). At the time of the postoperative telephone call, the Thaha et al. score decreased by 5.6 (p < 0.001), while the quality of life score decreased by 2 (p < 0.001). The Wexner score remained the same or improved for all patients except one. Treatment was unsuccessful for 6/67 patients (9%) and 10/61 patients (16.4%) experienced a subsequent recurrence in haemorrhoid symptoms. Only those over 51 years old were statistically associated with more frequent recurrences (p = 0.044). Conclusion: Doppler-guided haemorrhoidal artery ligation with mucopexy is an effective technique in the medium-term. Good tolerance in makes this treatment an attractive alternative to conventional haemorrhoidectomy.

RESUMO Experiência: A ligação de artéria hemorroidária com mucopexia orientada por Doppler é técnica cirúrgica minimamente invasiva. Esse procedimento é efetivo e menos doloroso do que a hemorroidectomia convencional. Métodos: Reunimos os prontuários de todos os pacientes operados entre novembro de 2012 e junho de 2014. Foram calculados escores pré-operatórios e pós-operatórios durante as consultas e, em seguida, por telefone. Tratamento cirúrgico malsucedido foi definido como a persistência dos sintomas de hemorroidas dentro de três meses após o procedimento, e recidiva foi definida por sintomas recorrentes depois do terceiro mês do pós-operatório. Resultados: Durante o período analisado, 70 pacientes passaram por procedimentos cirúrgicos consecutivos para prolapso de hemorroida (52%), sangramento (29%), ou ambos (17%). Para 87% dos pacientes, a hospitalização foi ambulatorial ou de pernoite. Não ocorreram complicações em 92,7% dos casos. O período médio de absenteísmo foi de 11 ± 6,5 dias. Os tempos transcorridos entre o procedimento e a última consulta no pós-operatório, seguida pelo contato telefônico, foram de respectivamente 2,7 ± 5,8 meses e 16,5 ± 4,9 meses. Por ocasião do contato telefônico no pós-operatório, o escore de Thaha et al. diminuiu em 5,6 pontos (p < 0,001), enquanto o escore de qualidade de vida diminuiu em 2 pontos (p < 0,001). O escore de Wexner permaneceu igual ou melhorou para todos os pacientes, exceto um. O tratamento não obteve sucesso para 6/67 pacientes (9%); e 10/61 pacientes (16,4%) sofreram uma subsequente recorrência nos sintomas hemorroidários. Apenas aqueles participantes com mais de 51 anos demonstraram associação estatística com recorrências mais frequentes (p = 0,044). Conclusão: A ligação de artéria hemorroidária com mucopexia orientada por Doppler é técnica efetiva no meio termo. A boa tolerância faz com que esse tratamento seja uma alternativa efetiva à hemorroidectomia convencional.
