French multicentre prospective evaluation of radiofrequency ablation in the management of haemorrhoidal disease.

PURPOSE: The aim of this study was to evaluate the efficacy and safety of radiofrequency ablation (RFA) in the management of haemorrhoidal disease with 1 year's follow-up. METHOD: This prospective multicentre study assessed RFA (Rafaelo©) in outpatients with grade II-III haemorrhoids. RFA was performed in the operating room under locoregional or general anaesthesia. Primary endpoint was the evolution of a quality-of-life score adapted to the haemorrhoid pathology (HEMO-FISS-QoL) 3 months after surgery. Secondary endpoints were evolution of symptoms (prolapsus, bleeding, pain, itching, anal discomfort), complications, postoperative pain and medical leave. RESULTS: A total of 129 patients (69% men, median age 49 years) were operated on in 16 French centres. Median HEMO-FISS-QoL score dropped significantly from 17.4/100 to 0/100 (p < 0.0001) at 3 months. At 3 months, the rate of patients reporting bleeding (21% vs. 84%, p < 0.001), prolapse (34% vs. 91.3%, p < 0.001) and anal discomfort (0/10 vs. 5/10, p < 0.0001) decreased significantly. Median medical leave was 4 days [1-14]. Postoperative pain was 4/10, 1/10, 0/10 and 0/10 at weeks 1, 2, 3 and 4. Seven patients (5.4%) were reoperated on by haemorrhoidectomy for relapse, and three for complications. Reported complications were haemorrhage (3), dysuria (3), abscess (2), anal fissure (1), external haemorrhoidal thrombosis (10), pain requiring morphine (11). Degree of satisfaction was high (+ 5 at 3 months on a - 5/+ 5 scale). CONCLUSION: RFA is associated with an improvement in quality of life and symptoms with a good safety profile. As expected for minimally invasive surgery, postoperative pain is minor with short medical leave. CLINICAL TRIAL REGISTRATION AND DATE: Clinical trial NCT04229784 (18/01/2020).

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.

Fistula Plug in Fistulising Ano-Perineal Crohn's Disease: a Randomised Controlled Trial.

BACKGROUND AND AIMS: Anal fistula plug [AFP] is a bioabsorbable bioprosthesis used in ano-perineal fistula treatment. We aimed to assess efficacy and safety of AFP in fistulising ano-perineal Crohn's disease [FAP-CD]. METHODS: In a multicentre, open-label, randomised controlled trial we compared seton removal alone [control group] with AFP insertion [AFP group] in 106 Crohn's disease patients with non- or mildly active disease having at least one ano-perineal fistula tract drained for more than 1 month. Patients with abscess [collection ≥ 3mm on magnetic resonance imaging or recto-vaginal fistulas were excluded. Randomisation was stratified in simple or complex fistulas according to AGA classification. Primary end point was fistula closure at Week 12. RESULTS: In all, 54 patients were randomised to AFP group [control group 52]. Median fistula duration was 23 [10-53] months. Median Crohn's Disease Activity Index at baseline was 81 [45-135]. Fistula closure at Week 12 was achieved in 31.5% patients in the AFP group and in 23.1 % in the control group (relative risk [RR] stratified on AGA classification: 1.31; 95% confidence interval: 0.59-4.02; p = 0.19). No interaction in treatment effect with complexity stratum was found; 33.3% of patients with complex fistula and 30.8% of patients with simple fistula closed the tracts after AFP, as compared with 15.4% and 25.6% in controls, respectively [RR of success = 2.17 in complex fistula vs RR = 1.20 in simple fistula; p = 0.45]. Concerning safety, at Week 12, 17 patients developed at least one adverse event in the AFP group vs 8 in the controls [p = 0.07]. CONCLUSION: AFP is not more effective than seton removal alone to achieve FAP-CD closure.

Ambulatory haemorrhoidal surgery: systematic literature review and qualitative analysis.

PURPOSE: The aims of this study are to review the advantages and drawbacks of the ambulatory management of patients scheduled for haemorrhoidal surgery and to highlight the reasons for unplanned hospital admission and suggest preventive strategies. METHODS: We conducted a systematic review of the literature from January 1999 to January 2013 using MEDLINE and EMBASE databases. Manuscripts were specifically analysed for failure and side effects of haemorrhoidal surgery in ambulatory settings. RESULTS: Fifty relevant studies (6082 patients) were retrieved from the literature review. The rate of ambulatory management failure ranged between 0 and 61%. The main reasons for failure were urinary retention, postoperative haemorrhage and unsatisfactory pain control. Spinal anaesthesia was associated with the highest rates of urinary retention. Doppler-guided haemorrhoidal artery ligation has less frequent side effects susceptible to impair ambulatory management than haemorrhoidectomy and stapled haemorrhoidopexy. However, the fact that haemorrhoidopexy is less painful than haemorrhoidectomy may allow ambulatory management. CONCLUSION: Day-case haemorrhoidal surgery can be performed whatever the surgical procedure. Postoperative pain deserves special prevention measures after haemorrhoidectomy, especially by using perineal block or infiltrations. Urinary retention is a common issue that can be responsible for failure; it requires a preventive strategy including short duration spinal anaesthesia. Doppler-guided haemorrhoidal artery ligation is easy to perform in outpatients but deserves more complete evaluation in this setting.

[Conventional surgical treatment of anal fistulas]. / Traitement chirurgical conventionnel des fistules anales.

Conventional treatment of anal fistulas depends from anatomical relationships of the fistula with striated sphincter complex. Location of primary opening is crucial, blind fistula does not exist. Low fistulas can be treated in a single procedure without remarkable consequence on continence. Anterior fistulas in female, multiparas and multioperated patients with impaired continence must be treated with caution with at least two stages. High anal fistulas will always be treated in several stages: first stage is drainage with a loose seton during two or three months followed by fistulotomy or cutting seton.

Worsening of hepatic dysfunction as a consequence of repeated hydroxyethylstarch infusions.

BACKGROUND/AIMS: Due to its apparent safety and low cost, hydroxyethylstarch (HES) is increasingly used as a volume expander. The aim of this retrospective study was to highlight the risk of hepatic dysfunction after iterative HES infusions. METHODS: Between April 1996 and April 1998, nine patients were referred for worsening of their clinical condition after repeated HES infusions. Six patients had previous chronic liver disease, cirrhosis in four cases. All patients underwent a liver biopsy. RESULTS: All post-HES liver biopsies showed diffuse microvacuolization of Kupffer cells, which was associated with focal hepatocyte vacuolization in seven cases. The vacuoles contained periodic acid Schiff positive material at their margins and were lysosomal by electron microscopy. The clinical symptoms of hepatic disease, although difficult to interpret in cirrhotic patients, worsened after HES infusions. Portal hypertension was noted in three non-cirrhotic patients. Serum alkaline phosphatase and gammaglutamyl transferase activities were increased when compared with previous values. Eight patients died, six of them within 1-4 weeks of hepatic failure or septic shock. In the only living patient, symptoms improved after HES withdrawal. CONCLUSIONS: Repeated administration of HES could favour severe portal hypertension, liver failure and sepsis, particularly in the setting of chronic liver disease. The basis of these adverse effects is the lysosomal storage of HES in Kupffer cells and hepatocytes.

[Anal suppurations]. / Suppurations anales.

Anal suppurations can be classified according to their origin: from the anal canal, from above the anal canal, or independent from the ano-rectum. Wherever suppuration comes from, an abscess can be present at the acute phase. Anal fistulas represent about 70% of anal suppurations. They always begin by cryptoglandular infection, which can spread to the intersphincteric space and then pass through the anal sphincter. Treatment of anal fistula is a double challenge: healing the suppuration, and preserving anal continence. Among suppurations independent from the ano-rectum pilonidal disease is the most frequent (15% of the suppurations). Other causes of ano-perineal suppurations are infected fissure, Verneuil's disease, and gland, recto-vaginal fistulas and Crohn's disease.
