Screening for precancerous anal lesions linked to human papillomaviruses: French recommendations for clinical practice.

In France, about 2000 new cases of anal cancer are diagnosed annually. Squamous cell carcinoma is the most common histological type, mostly occurring secondary to persistent HPV16 infection. Invasive cancer is preceded by precancerous lesions. In addition to patients with a personal history of precancerous lesions and anal cancer, three groups are at very high risk of anal cancer: (i) men who have sex with men and are living with HIV, (ii) women with a history of high-grade squamous intraepithelial lesions (HSILs) or vulvar HPV cancer, and (iii) women who received a solid organ transplant more than 10 years ago. The purpose of screening is to detect HSILs so that they can be treated, thereby reducing the risk of progression to cancer. All patients with symptoms should undergo a proctological examination including standard anoscopy. For asymptomatic patients at risk, an initial HPV16 test makes it possible to target patients at risk of HSILs likely to progress to cancer. Anal cytology is a sensitive test for HSIL detection. Its sensitivity is greater than 80% and exceeds that of proctological examination with standard anoscopy. It is indicated in the event of a positive HPV16 test. In the presence of cytological abnormalities and/or lesions and a suspicion of dysplasia on clinical examination, high-resolution anoscopy is indicated. Performance is superior to that of proctological examination with standard anoscopy. However, this technique is not widely available, which limits its use. If high-resolution anoscopy is not possible, screening by a standard proctological examination is an alternative. There is a need to develop high-resolution anoscopy and triage tests and to evaluate screening strategies.

Management of perianal fistulas in Crohn's disease: a 2021 update of the French National Society of Coloproctology consensus.

BACKGROUND: Since our last publication of algorithms for the management of perianal fistulas in patients with Crohn's disease, researchers have proposed a treat to target strategy systematic combotherapy for anal lesions, and indications for stem cell injection. In the absence robust publications, the Société Nationale Française de Coloproctologie (French National Society of Coloproctology [SNFCP]) wished to establish a group consensus using the Delphi method. METHODS: From October 2020 to January 2021, a scientific committee and panel of gastroenterologists and surgeons established answers which were submitted to the members of the SNFCP during a national conference in November 2020. Three questions were clarified and reformulated, and then submitted during a third and final round of consultation of members of the SNFCP. RESULTS: The target was defined as being the response obtained in every domain (symptoms, physical and radiological evaluation) which could be considered satisfactory, without the need to intensify therapeutic management. By consensus, the time required for clinical evaluation of the efficacy of treatment was 6 months. A response on magnetic resonance imaging (MRI) should include the absence of a collection of 10 mm or more in size at 6 months, and a frank decrease or complete disappearance of hyperintensity in T1 and T2 sequences of the main tract at 12 months. Systematic association of an immunosuppressant with tumor necrosis factor inhibitors did not reach the consensus level for adalimumab (50%), but just did for infliximab (70%). The majority of the respondents considered failure of one, or even two lines of different biotherapies to be potential indications for injection of stem cells. CONCLUSIONS: These findings reinforce the importance of composite targets including MRI evaluation, and underscore the need for precise timing of evaluation. Combotherapy is only recommended with infliximab. Injection of stem cells is a second- or third-line option.

How to manage anal ulcerations and anorectal stenosis in Crohn's disease: algorithm-based decision making : French National Working Group Consensus 2018.

The French National Society of Coloproctology established national recommendations for the treatment of anoperineal lesions associated with Crohn's disease. Treatment strategies for anal ulcerations and anorectal stenosis are suggested. Recommendations have been graded following international recommendations, and when absent professional agreement was established. For each situation, practical algorithms have been drawn.

Online training on how to diagnose anoperineal lesions of Crohn's disease: Do pictures matter? A nationwide randomized study.

Any gastroenterologist must be trained to properly diagnose anoperineal lesions in patients with Crohn's disease (APLOC). The aim of this study was to establish whether adding pictures would improve teaching effectiveness of the diagnosis of APLOC to French gastroenterology trainees. METHOD: Trainees were asked to answer a first web-based survey consisting of evaluating 12 pictures of APLOC with a closed answer questionnaire. They were then randomized in 2 groups. Group A received an online teaching with typical pictures and APLOC definitions and group B definitions only. Trainees were asked again seven days later to answer a second survey with 12 other pictures of APLOC and 14 experts also answered this survey. Diagnostic scores were expressed in %. The primary endpoint was the comparison of the score of survey 2 between the two groups of trainees. Secondary endpoints were to compare results of survey 2 between trainees of both groups and experts, and assess diagnosis of each lesion. RESULTS: Two hundred fourty eight trainees among 465 answered survey 1, and 195 survey 2. The diagnostic score was 71.9% for groups A and B and 74.6% for experts (differences NS). After training diagnosis of ulceration was 72% for group A and 72.9% for group B, fistulae 85.2% versus 85.8%, erythema 44.1% vs. 55.6%, anoperineal scars 67.5% vs. 65.6%, and abscess 100% (differences NS). CONCLUSION: There was no difference between the two teaching methods. Further research should be performed aiming at improving teaching material and quotation baremes.

Management of anoperineal lesions in Crohn's disease: a French National Society of Coloproctology national consensus.

The French National Society of Coloproctology established national recommendations for the treatment of anoperineal lesions associated with Crohn's disease. Treatment strategies for acute abscesses, active fistulas (active denovo and still active under treatment), fistulas in remission, and rectovaginal fistulas are suggested. Recommendations have been graded following the international recommendations, and when absent, professional agreement has been established. For each situation, practical algorithms have been drawn.

Anoperineal lesions in Crohn's disease: French recommendations for clinical practice.

BACKGROUND: Anoperineal lesion (APL) occurrence is a significant event in the evolution of Crohn's disease (CD). Management should involve a multidisciplinary approach combining the knowledge of the gastroenterologist, the colorectal surgeon and the radiologist who have appropriate experience in this area. Given the low level of evidence of available medical and surgical strategies, the aim of this work was to establish a French expert consensus on management of anal Crohn's disease. These recommendations were led under the aegis of the Société Nationale Française de Colo-Proctologie (SNFCP). They report a consensus on the management of perianal Crohn's disease lesions, including fistulas, ulceration and anorectal stenosis and propose an appropriate treatment strategy, as well as sphincter-preserving and multidisciplinary management. METHODOLOGY: A panel of French gastroenterologists and colorectal surgeons with expertise in inflammatory bowel diseases reviewed the literature in order to provide practical management pathways for perianal CD. Analysis of the literature was made according to the recommendations of the Haute Autorité de Santé (HAS) to establish a level of proof for each publication and then to propose a rank of recommendation. When lack of factual data precluded ranking according to the HAS, proposals based on expert opinion were written. Therefore, once all the authors agreed on a consensual statement, it was then submitted to all the members of the SNFCP. As initial literature review stopped in December 2014, more recent European or international guidelines have been published since and were included in the analysis. RESULTS: MRI is recommended for complex secondary lesions, particularly after failure of previous medical and/or surgical treatments. For severe anal ulceration in Crohn's disease, maximal medical treatment with anti-TNF agent is recommended. After prolonged drainage of simple anal fistula by a flexible elastic loop or loosely tied seton, and after obtaining luminal and perineal remission by immunosuppressive therapy and/or anti-TNF agents, the surgical treatment options to be discussed are simple seton removal or injection of the fistula tract with biological glue. After prolonged loose-seton drainage of the complex anal fistula in Crohn's disease, and after obtaining luminal and perineal remission with anti-TNF ± immunosuppressive therapy, surgical treatment options are simple removal of seton and rectal advancement flap. Colostomy is indicated as a last option for severe APL, possibly associated with a proctectomy if there is refractory rectal involvement after failure of other medical and surgical treatments. The evaluation of anorectal stenosis of Crohn's disease (ARSCD) requires a physical examination, sometimes under anesthesia, plus endoscopy with biopsies and MRI to describe the stenosis itself, to identify associated inflammatory, infectious or dysplastic lesions, and to search for injury or fibrosis of the sphincter. Therapeutic strategy for ARSCD requires medical-surgical cooperation.

Guidelines for the treatment of hemorrhoids (short report).

Hemorrhoids are a common medical problem that is often considered as benign. The French Society of Colo-Proctology (Société nationale française de colo-proctologie [SNFCP]) recently revised its recommendations for the management of hemorrhoids (last issued in 2001), based on the literature and consensual expert opinion. We present a short report of these recommendations. Briefly, medical treatment, including dietary fiber, should always be proposed in first intention and instrumental treatment only if medical treatment fails, except in grade ≥III prolapse. Surgery should be the last resort, and the patient well informed of the surgical alternatives, including the possibility of elective ambulatory surgery, if appropriate. Postoperative pain should be prevented by the systematic implementation of a pudendal block and multimodal use of analgesics.

The outcome of fistulotomy for anal fistula at 1 year: a prospective multicentre French study.

AIM: The study aimed to evaluate outcome at 1 year of one- and two-stage fistulotomy for anal fistula in a large group of patients. METHOD: A prospective multicentre observational study was designed to include patients with anal fistula treated by one- or two-stage fistulotomy. Data were collected using a self-administered questionnaire before surgery, during healing and at 1 year after surgery. RESULTS: Group A (133 patients) with a low anal fistula underwent a one-stage fistulotomy. The median Wexner scores before and after surgery were 1.0 (0-11) and 2.0 (0-18) (P = 0.032) and the median Vaizey scores were 2.0 (0-14) and 3.0 (0-21) (P = 0.055). The Wexner scores and percentage of patients before and after fistulotomy were as follows: 0-5: 88%, 86%; 6-10: 10.7%, 10.7%; 11-15: 1.0%, 2.6%; and 16-20: 0%, 2%. Eighty-seven per cent of the patients were satisfied. Group B (62 patients) underwent two-stage fistulotomy for a high transsphincteric fistula. The Wexner scores and percentage of patients before the first stage and 1 year after the second stage were as follows: 0-5: 86%, 66%; 6-10: 4.5%, 20%; 11-15: 9%, 11%; and 16-20: 0%, 2%. The median Wexner scores before the first stage and after the second stage were 1 (0-14) vs. 4 (0-19) (P < 0.001), and the median Vaizey scores were 1.5 (0-11) vs. 4 (0-20) (P < 0.001). Eighty-eight per cent of the patients were satisfied. CONCLUSION: Low transsphincteric anal fistula can be treated by fistulotomy without clinically significant continence disturbance. Treating high transsphincteric anal fistulae with two-stage fistulotomy is followed by mild continence disturbance. Satisfaction rates were high.

The results of seton drainage combined with anti-TNFα therapy for anal fistula in Crohn's disease.

AIM: Combined infliximab and sphincter-sparing surgery can be effective in perianal fistula associated with Crohn's disease (CD). This study aimed to assess the efficacy of local surgery combined with infliximab on sustained fistula closure and to identify predictive factors for response after this combined treatment. METHOD: Between 2000 and 2010, 81 patients with fistulising perianal CD were included in this observational study. Drainage with a loose seton was followed by infliximab therapy. The primary end-points were the rate of complete fistula closure and time required for this to occur. RESULTS: The fistula was complex in 71 (88%) of the 81 patients. Local proctological surgery was carried out in 77 (95%), including seton drainage in 62 (80.5%) of these. This was continued for a median duration of 3.8 months and the patient then received infliximab therapy. The median follow-up after treatment was 64 months (2-263). Initial complete closure of the fistula occurred in 71 (88%) cases at a median interval of 12.4 months (1-147) from the start of treatment. Recurrence was observed in 29 (41%) patients at a median interval of 38.5 months (2-48) from the start of treatment. They were treated again with combined treatment with successful closure in 19 (65.5%) patients. The total rate of closure of the fistula was 75.3%. Female gender, anal stenosis, rectovaginal and complex fistula formation were factors independently associated with failure of combined treatment. CONCLUSION: Seton drainage for several months combined with infliximab therapy is effective in closing the fistula in 75% of patients with complex perianal fistula formation associated with CD.

Sphincter-sparing anal-fissure surgery: a 1-year prospective, observational, multicentre study of fissurectomy with anoplasty.

AIM: Internal sphincterotomy is the standard surgical treatment for chronic anal fissure, but is frequently complicated by anal incontinence. Fissurectomy is proposed as an alternative technique to avoid sphincter injury. We describe 1-year outcomes of fissurectomy. METHOD: This was a prospective, multicentre, observational study. All patients with planned surgery for chronic anal fissure were included and had fissurectomy. Data were collected before surgery, at healing, and 1 year after fissurectomy. Patient self-assessed anal symptoms and quality of life (using the 36-item short-form health survey [SF-36] questionnaire). Presurgical and postsurgical variables were compared using the Wilcoxon signed-rank test for paired samples. RESULTS: Two-hundred and sixty-four patients were included (median age, 45 years; 52% women). Anoplasty was associated with fissurectomy in 83% of the 257 documented cases. The main complications were urinary retention (n = 3), local infection (n = 4) and faecal impaction (n = 1). Healing was achieved in all patients at a median of 7.5 weeks after surgery. No recurrence occurred. At 1 year, 210 (79%) questionnaires were returned. Median anal pain had dropped from 7.3/10 to 0.1/10 (P < 0.001), anal discomfort had decreased from 5.0/10 to 0.1/10 (P < 0.001) and the Knowles-Eckersley-Scott Symptom constipation score had decreased from 9/45 to 5/45 (P < 0.001). There was a nonsignificant increase in the Wexner anal incontinence score, from 1/20 to 2/20. De-novo clinically significant anal incontinence (Wexner score > 5) affected 7% of patients at 1 year, but presurgical incontinence had disappeared in 15% of patients. All SF-36 domains significantly improved. Anoplasty did not impact any result. CONCLUSION: Given its high rate of healing and low rate of de-novo anal incontinence, fissurectomy with anoplasty is a valuable sphincter-sparing surgical treatment for chronic anal fissure.

One-year outcome of haemorrhoidectomy: a prospective multicentre French study.

AIM: An evaluation was performed of the 1-year outcome of open haemorrhoidectomy (Milligan and Morgan alone or with posterior mucosal anoplasty [the Leopold Bellan procedure]). METHOD: A prospective, multicentre, observational study included all patients having a planned haemorrhoidectomy from January 2007 to June 2008. Data were collected before surgery, and at 3 months and 1 year after surgery. Patients assessed their anal symptoms and quality of life (SF-36). RESULTS: Six-hundred and thirty-three patients (median age = 48 years, 56.5% women) underwent haemorrhoidectomy either by the Milligan and Morgan procedure alone (n = 231, 36.5%) or together with the Leopold Bellan procedure (posterior mucosal anoplasty) for resection of a fourth haemorrhoid (n = 345, 54.5%), anal fissure (n = 56, 8.9%) or low anal fistula (n = 1, 0.16%). The median healing time was 6 weeks. Early complications included urinary retention (n = 3), bleeding (n = 11), local infection (n = 7) and faecal impaction (n = 9). At 1 year, the main complications included skin tags (n = 2) and anal stenosis (n = 23). There were three recurrences requiring a second haemorrhoidectomy. On a visual analogue scale, anal pain at 1 year had fallen from a median of 5.5/10 before treatment to 0.1/10 (p < 0.001), anal discomfort from 5.5/10 to 0.1/10 (P < 0.001) and the Knowles-Eckersley-Scott Symptom (KESS) constipation score from 9/45 to 6/45 (P < 0.001). The median Wexner score for anal incontinence was unchanged (2/20). De-novo anal incontinence (a Wexner score of >5) affected 8.5% of patients at 1 year, but preoperative incontinence disappeared in 16.7% of patients with this symptom. All physical and mental domains of quality of life significantly improved, and 88% of patients were satisfied or very satisfied. CONCLUSION: Complications of open haemorrhoidectomy were infrequent. Anal continence was not altered. Comfort and well-being were significantly improved at 1 year after surgery. Patient satisfaction was high despite residual anal symptoms.

[Specific respiratory manifestations associated with hemorrhagic rectocolitis. Analysis of a case and review of the literature]. / Manifestations respiratoires spécifiques associées à la rectocolite hémorragique. Analyse d'un cas et revue de la littérature.

Respiratory impairments occurring as systemic manifestations of ulcerative colitis are often misinterpreted. We report a case of chronic productive bronchitis associated with ulcerative colitis; symptoms appeared after colectomy. Clinical features distinguished it from common chronic bronchitis: it occurred in a woman without respiratory disease or smoking history, a chronic productive cough without bronchiectasis, negative infectious investigations, severe endoscopic and histologic lesions, and above all remarkable steroid efficacy. Systematic research and early treatment of these manifestations avoids aggravating pulmonary disease, especially secondary bronchiectasis. Though less frequent, other respiratory manifestations of ulcerative colitis have been described, such as asphyxiating tracheal stenosis, pneumonia or interstitial pulmonary diseases, pleurisy or pleuro-pericarditis.

Differences between jejunal myoelectric activity after a meal and during phase 2 of migrating motor complexes in healthy humans.

Using an intraluminal probe with six pairs of annular electrodes, the myoelectric activity of the proximal jejunum was recorded during 48-hr sessions in 16 healthy volunteers receiving evening and noon meals (1000 kcal) and breakfast (400 kcal). In 10 subjects receiving no drug, the characteristics of the migrating motor complexes (period, duration of each phase, velocity of propagation of phase 3, duration of the postprandial disruption) varied markedly between subjects but were relatively constant from the first to the second day of recording. Single spike bursts propagated at a rate of 2-5 cm/sec, clusters of 3-10 spike bursts propagated at a rate of 0.5-1 cm/sec, and similar clusters recurring repetitively each 1.5-2 min were observed after the meals and very rarely in the fasted state during phase 2 of nocturnal migrating motor complexes. In six subjects, oral administration of codeine (50 mg) 1 hr before a meal induced migrating motor complexes in the postprandial state, with characteristics similar to that observed in the fasted state except a longer duration of phase 2. Single spike bursts and isolated and repetitive clusters of spike bursts were observed during phase 2 of the codeine-induced migrating motor complexes and after meals preceded by placebo, but very rarely during the phase 2 of nocturnal (fasted state) migrating motor complexes. It is concluded that the patterns of jejunal contractions consisting of propagated single spike bursts and isolated or repetitive spike bursts characterize the postprandial state in healthy humans and are dependent upon digesta flow.
