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.

[New paradigm for haemorrhoidal disease treatment]

NEW PARADIGM FOR HAEMORRHOIDAL DISEASE TREATMENT. The modern surgical management of hemorrhoidal disease was born in 1937, without any great variation until the 90s. Later then, the quest for a surgery without pain or secondary complications has stimulated the appearance of new techniques, often dependent on sophisticated technologies, the most recent being still under evaluation. At the same time, conventional excision surgery has evolved to become less aggressive. Overall, the requirement for less morbidity has become a priority, exceeding that of the long-term efficacy, and the cost of those interventions based on sophisticated technologies has significantly increased.

Prospective and multicentre study of radiofrequency treatment in anal fistula

BACKGROUND

The most effective treatment for anal fistula is fistulotomy, but it involves a risk of anal incontinence. To reduce this morbidity, sphincter-sparing treatments have been developed, but their success in real life is often less than 50%. The aim is to determine the clinical healing rate 6 months after radiofrequency treatment.

METHODS

We planned to evaluate 50 patients from three French proctology centres. Treatment efficacy was evaluated at 6 and 12 months by means of clinical and magnetic resonance imaging examination. We evaluated morbidity and healing prognostic factors.

RESULTS

Fifty patients with a mean age of 51 years (22-82) were included. Eleven patients had a low trans-sphincteric fistula (LTS), 21 patients had a high trans-sphincteric fistula (HTS), eight had a complex fistula and nine had Crohn's disease fistula. After 6 months, 17 patients (34.7%) had a clinically healed fistula, including five (45.5%) with LTS fistula, seven (33.3%) with HTS fistula, one (12.5%) with complex fistula, four (44.4%) with Crohn's disease, with no significant difference between these fistula types (p: 0.142). At 12 months, the healing rate was identical. MRI in 15 out of 17 clinically healed patients showed a deep remission of 73.3% at 12 months. Energy power was associated with the success of the treatment. There was an 8.2% incidence of post-surgical complications with 4.1% being abscesses (one required surgical management). Postoperative pain was minor. No new cases or deterioration of continence have been shown.

CONCLUSION

Radiofrequency is effective in 34.7% of the cases as an anal fistula treatment in this first prospective study, with low morbidity and no effect on continence. Clinical healing was deep (MRI) in three-quarters at 1 year. The increase in energy power during the procedure seems to be a key point to be analysed to optimise results.

Surgical closure, mainly with glue injection and anti-tumour necrosis factor α, in fistulizing perianal Crohn's disease: A multicentre randomized controlled trial

AIM

In patients with fistulizing perianal Crohn's disease (CD), the need for a secondary surgical step is not defined. The aim was to assess the efficacy of surgical closure compared to a single seton removal in patients with drained fistulizing perianal CD treated with adalimumab.

METHODS

This was a multicentre, randomized controlled trial, comparing seton removal + surgical closure (closure group) to seton removal alone (control group) with a stratification according to the American Gastroenterological Association classification. The primary end-point was fistula closure at month 12 defined by the association of the following criteria: no seton, absence of a visible external opening, absence of discharge from the tract after finger compression, absence of an internal opening, absence of perianal pain/abscess and absence of fistula-related abnormalities.

RESULTS

Among the 64 included patients (262 expected) (48 complex fistula, 75%), 33 were randomized to the closure group and 31 to the control group. In the closure group, 26 patients (78.8%) had glue. At month 12, overall fistula closure was achieved in 35 of the evaluable 58 patients (60%): 18/32 (56%) in the surgery group and 17/26 (65%) in the control group (P = 0.479). In the closure group, fistula closure was observed in 13/25 (52%) and 5/7 (71%) patients with complex and simple fistula respectively (P = 0.426), compared with 12/18 (67%) and 5/8 (63%), respectively in the control group (P = 1.000).

CONCLUSIONS

Seton removal alone seems to be no more effective than a secondary surgical step (in particular glue injection) in patients having fistulizing perianal CD controlled by an initial drainage combined with adalimumab. The results should be interpreted with caution.

Assessment of sexual dysfunction in patients with perianal Crohn's disease

AIM

Over the past 10 years, several studies have focused on sexuality in patients with Crohn's disease. Very few of them specifically focused on perianal disease (PD). This study aimed to compare the prevalence of sexual dysfunction (SD) in Crohn's disease patients with active PD versus controls without active PD.

METHOD

Patients from 14 French centres with active PD, defined by the presence of symptomatic ulceration, fistula or stenosis, were arbitrarily included. They were compared with controls from the existing SEXIA cohort. Men completed the International Index of Erectile Function (IIEF) and women the Female Sexual Function Index (FSFI). The primary end-point was SD defined by FSFI < 26.55 in women and IIEF < 42.9 in men.

RESULTS

Ninety-seven patients (64 women, 33 men) and 238 controls (131 women, 107 men) were included. SD was found in 66% of the female patients versus 50% of the controls (P = 0.04). In the male population, SD was found in 30% of the cases versus 16% of the controls (P = 0.06). Erectile dysfunction affected 46% of the male patients and 43% of the controls (P = 0.8). On multivariate analysis, the predictive factor most strongly associated with SD in women was severely active anal PD defined by a perineal disease activity index > 4 [OR = 13.05 (2.32-73.44)].

CONCLUSION

Women with active PD had an increased prevalence of SD compared with controls without active PD. In the male population, the study was unable to determine whether there was a difference as it was underpowered.

Pedictors of Perianal Fistula Relapse in Crohn's Disease

BACKGROUND

Despite an optimal medico-surgical management of perineal Crohn's disease (PCD), fistula relapse still occurs in 30% of patients. Our aim was to determine predictors of fistula relapse in patients in remission after treatment of a PCD lesion.

METHODS

Consecutive patients treated for fistulizing PCD have been included in a retrospective study when they achieved fistula remission within 3 months after the surgery. Remission was defined as the absence of any draining fistula at clinical examination. Primary outcome was the occurrence of a fistula relapse, defined as a subsequent perianal draining fistula or an abscess confirmed clinically and/or by pelvic MRI.

RESULTS

One hundred and thirty-seven patients (57% female, median age: 35 years) corresponding to 157 abscess events, including 120 (76.4%) treated by anti-TNF after drainage, achieved fistula remission after surgery. During the follow-up period (median duration: 43 months [interquartile range 26 to 64]), 34 (22%) patients experienced a fistula relapse within a median time of 1.8 years. Survival without fistula was 96.7% at 1 year, 78.4% at 3 years, and 74.4% at 5 years. Fistula relapse rates were not different in patients receiving infliximab or adalimumab (P = 0.66). In patients treated by anti-TNF at inclusion, discontinuation of anti-TNF therapy (odds ratio 3.49, P = 0.04), colonic location (OR 6.25, P = 0.01), and stricturing phenotype (odds ratio 4.39, P = 0.01) were independently associated with fistula relapse in multivariate analysis.

CONCLUSION

In patients achieving fistula remission of PCD, relapse rates are low and are not different between infliximab and adalimumab. Discontinuation of anti-TNF therapy is associated with increased relapse rate.

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.

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.

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.

[Anal acute pain]

Anal acute pain. Anal pain is a symptom commonly reported during consultation for ano-rectal disease. It is a nonspecific symptom, associated with both emergency and chronic pathologies, and with both benign and serious conditions. Aetiological diagnosis is not always easily established during initial visit. In a patient without significant past medical history, when no sign of severe problem is present, and when clinical examination is normal, a second visit can help establishing diagnosis. When an abscess is suspected, antibiotherapy will not cure the patient, and may expose to occurrence of septic complications. When immediate intervention for an abscess is not possible, incision will control pain and infection for a few days. Haemorrhoidal thrombosis is another frequent aetiology of acute pain. Diagnosis is not difficult, and when appropriate medical treatment does not alleviate pain, incision under local anaesthesia is indicated. Pain associated with anal fissure is typicaly ryhthmed by stool passage. For non healing fissures, surgery may be proposed. Fecaloma, trauma, herpes virus infection and foreign body are less frequent, and clinical context is often suggestive.

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.

Treatment of anal fistula and abscess

The glands of Hermann and Desfosses, located in the thickness of the anal canal, drain into the canal at the dentate line. Infection of these anal glands is responsible for the formation of abscesses and/or fistulas. When this presents as an abscess, emergency drainage of the infected cavity is required. At the stage of fistula, treatment has two sometimes conflicting objectives: effective drainage and preservation of continence. These two opposing constraints explain the existence of two therapeutic concepts. On one hand the laying-open of the fistulous tract (fistulotomy) in one or several operative sessions remains the treatment of choice because of its high cure rates. On the other hand surgical closure with tract ligation or obturation with biological components preserves sphincter function but suffers from a higher failure rate.

Treatments of faecal incontinence: recommendations from the French national society of coloproctology

Faecal incontinence is common and significantly affects quality of life. Its treatment involves dietary manipulation, medical treatments, perineal rehabilitation or surgery. In this paper, the French National Society of Coloproctology offers recommendations based on the data in the current literature, including those on recently developed treatments. There is a lack of high quality data and most of the recommendations are therefore based either on grade of recommendation B or expert recommendation (Level 4). However, the literature supports the construction of an algorithm based on the available scientific evidence and expert recommendation which may be useful in clinical practice. The French National Society of Coloproctology proposes a decision-making algorithm that includes recent developments of treatment. The current recommendations support sacral nerve modulation as the key treatment for faecal incontinence. They do not support the use of sphincter substitutions except in certain circumstances. Transanal irrigation is a novel often successful treatment of faecal incontinence due to neurological disorders.

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.

Do we have to stop anticoagulant and platelet-inhibitor treatments during proctological surgery?

AIM

This prospective observation study evaluated the incidence of secondary bleeding after proctological surgery without interruption of oral anticoagulant or platelet-inhibitor treatments.

METHOD

The number of episodes of postoperative bleeding was identified prospectively from the day of surgery to the last follow-up visit in consecutive patients operated on during 2010 in two units dedicated to proctology.

RESULTS

A total of 2513 procedures were performed in 2314 patients (1379 men), 46 ± 16 years of age. Secondary bleeding occurred after 115 (4.6%) procedures, no later than day 24 after surgery, requiring rehospitalization in 86% of cases and further surgery and/or transfusion in 36%. The highest frequency was noted after surgery for haemorrhoids (haemorrhoidopexy, 7.9%; haemorrhoidectomy, 6.2%) (P = NS and transanal excision of rectal tumours (6.5%). On multivariate analysis, the frequency was significantly increased by clopidogrel (15%) [relative risk (RR) = 10). In patients on oral anticoagulants, bleeding occurred in 23% (RR = 5.8) if the anticoagulants were not interrupted and in 57% (RR = 42) if the anticoagulants were discontinued and replaced with heparin.

CONCLUSION

During proctological surgery the overall risk of postoperative bleeding is low, but it can occur up to 3 weeks after surgery and is often severe. Maintenance treatment with oral anticoagulants is the most important risk factor, aggravated by a change to heparin. Clopidogrel also significantly increases the bleeding risk.

[Surgical treatment of haemorrhoidal disease]

Haemorrhoidal disease is always benign. Are only operated on patients who are handicapped in their every day life, and for whom more conservative techniques failed or are at great chance for failure. Among numerous surgical procedures, only two have been extensively evaluated: pedicular haemorrhoidectomy, and Longo's procedure. The former is more efficient at long term, but exposes to more painful and prolonged postoperative course. The latter exposes to more recurrences, and its indications are more elective. Patient must be informed of potential risks associated with surgery, because they interfere with therapeutic proposal.

Prospective survey of secondary bleeding following anorectal surgery in a consecutive series of 1,269 patients

INTRODUCTION

As little data is available about secondary bleeding after proctological surgery, we conducted a specific survey.

PATIENTS AND METHODS

Patients operated between November 2008 and April 2009 were prospectively included. Patients were followed until last visit (day 21-28). Severity of bleeding was low (at home stay), moderate (hospitalisation for observation), or severe (transfusion, and/or homeostasis in operating room).

RESULTS

Included were 1269 patients: haemorrhoidectomy/pexy 527 (41%), fistula treatment 273 (21%), fissurectomy 197 (15%), perianal and pilonidal abscesses 124 (10%), others 148 (12%). Before surgery 78 patients were under long-term treatment with antiplatelet or anticoagulant therapy. Seventy-eight patients (6%) demonstrated 85 bleeding events. Severity rate was: low 22%, moderate 51%, and severe 27%. Ninety-five percent of events occurred before day 15. Univariate study showed increased risk after haemorrhoidopexy (P<10-3) and anticoagulant treatment (P = 0.002), decreased risk after fissurectomy and fistulotomy (P<10-3), and no relation with age, sex or operator. After multivariate study only relationship with anticoagulant treatment remained significant.

CONCLUSION

Secondary bleeding occurred in 6% of patients after proctological surgery, requiring a readmission and/or an active treatment in about 75%. Treatment with anticoagulant exposed to increased bleeding frequency.

Combined approach with infliximab, surgery, and methotrexate in severe fistulizing anoperineal Crohn's disease: results from a prospective study

BACKGROUND

Infliximab is the only medical therapy that has been proven to be effective in fistulizing Crohn's disease (CD), but the recurrence rate of fistulas is high despite maintenance therapy. The aim of this prospective study was to evaluate the short- and long-term efficacy of a combined schedule with infliximab, methotrexate, and sphincter-sparing surgery in patients with severe fistulizing anoperineal CD.

METHODS

From January 2006 to November 2007, all consecutive patients in three referral centers with severe fistulizing anoperineal CD were prospectively included after primary drainage. At inclusion, patients received three infliximab infusions at weeks 0, 2, and 6, and maintenance therapy with methotrexate. A second optimized surgical step consisting of at least removal of setons was performed between the second and the third infliximab infusions.

RESULTS

Thirty-four CD patients (26 women; median age 38.5 years) with complex anoperineal fistula were enrolled (including 9 with recto-vaginal fistulas, and 10 with anorectal stenosis). At week 14 the response rate was 85% with 74% complete responders. At 1 year, 50% were still responders; luminal CD worsening was the major cause of relapse. Median Perineal Disease Activity Index (PDAI) and magnetic resonance imaging (MRI) scores significantly decreased from baseline to week 50.

CONCLUSIONS

A combined approach with infliximab induction, two surgical sphincter-sparing steps and methotrexate is effective in achieving short-term response in severe fistulizing anoperineal CD. The best maintenance regimen remains to be determined.

STARR with Contour Transtar: prospective multicentre European study

OBJECTIVE

The stapled transanal rectal resection (STARR) in patients with defecation disorders is limited by the shape and capacity of the circular stapler. A new device has been recently developed, the Contour Transtar stapler, in order to improve the safety and effectiveness of the STARR technique. The study has been designed to confirm this declaration.

METHOD

From January to June 2007 a prospective European multicentre study of consecutive patients with defecation disorder caused by internal rectal prolapse underwent the new STARR technique. The assessment of perioperative morbidity and functional outcome after 6 weeks, 3 and 12 months was documented by different scores.

RESULTS

In all 75 patients, median age 64, the Transtar procedure was performed with 9% intraoperative difficulties, 7% postoperative complications and no mortality. The mean reduction of the ODS score was -15.6 (95%-CI: -17.3 to -13.8, P < 0.0001), mean reduction of SSS was -12.6 (95%-CI: -14.2 to -11.2; P < 0.0001). 41% stated improvement of their continence status by CCF score, only 4 patients (5%) had deterioration.

CONCLUSION

The Transtar procedure is technically demanding, with good functional results similar to the conventional STARR.

[Haemorrhoidal disease]

Hemorrhoids are normal component of anal canal anatomy, potential factors such as heredity rend them symptomatic. Hemorrhoidal disease is more or less severe, but always remains benign. It is a frequent affection: almost half of the French population suffers once a year from benign anorectal symptoms, including hemorrhoidal. Only 20% visit a medical doctor. Diagnosis is clinical and always set up after having ruled out another locoregional pathology. Colonoscopy indication should be large, but not abusive. First intention local and systemic medical treatment has proved their efficay. To unsatisfied patients, instrumental or surgical treatment may be offered. Instrumental treatment exposes to rare complications, and results are modest, deteriorating with time. Severe symptoms in a patient asking for the most efficacious technique, may lead to surgery. Surgery morbidity has decreased, due to less aggressive surgical dissection, innovations in procedures and instrumentation.

Decision-making algorithm for the STARR procedure in obstructed defecation syndrome: position statement of the group of STARR Pioneers

Internal rectal prolapse (rectal intussusception) and rectocele are frequent clinical findings in patients suffering from refractory constipation that may be best characterized as obstructive defecation syndrome. However, there is still no clear evidence whether the stapled transanal rectal resection (STARR) procedure provides a safe and effective surgical option for symptom resolution in patients with obstructive defecation syndrome, as evidence-based guidelines and functional long-term results are still missing. On the basis of the need for objective evaluation, a European group of experts was founded (Stapled Transanal Rectal Resection Pioneers). Derived from 2 meetings (October 26-28, 2006, Gouvieux, France and November 28-29, 2007, St Gallen, Switzerland) a concept for treatment options in patients suffering from obstructive defecation syndrome was developed, including a clear decision-making algorithm specifically focusing on the role of the stapled transanal rectal resection procedure based on clinical symptoms and dynamic imaging and inclusion and exclusion criteria for the stapled transanal rectal resection procedure.

Ano-rectal complaints in general practitioner visits: consumer point of view

AIMS

The perception patients consulting for primary care have of anorectal disorders has never been evaluated. Our aim was to analyze proctological complaints among outpatients consulting general practitioners.

PATIENTS AND METHODS

Among 1484 physicians who responded to a nationwide mailing in France, 161 enrolled 437 females and 358 males consulting between October 2004 and December 2005.

RESULTS

Females were younger than males (46 +/- 15 vs 51 +/- 13 years) (p<0.0001). Intermediate and upper social-occupational categories were overrepresented as compared with the general population. Symptoms were pain (48%), bleeding (37%), swelling (26%) and pruritus (24%). For 76%, these symptoms persisted for less than one month and 58% mentioned earlier visits or prior treatment. The first manifestation was correlated with a pregnancy in 31% of women. Present symptoms were secondary to acute constipation (52%), stress (33%), ingestion of spices (29%) or alcohol (20%), and diarrhea (8%). Symptoms were considered important in 61% or a cause of anxiety in 33% of patients. Treatment was prescribed for all patients: ointments (90%), phlebotonics (66%) or suppositories (51%), in combination for 75% of prescriptions. Patients preferred oral medicines (41%), ointments (30%) and suppositories (7%).

CONCLUSION

Proctological complaints are a reason for repeated visits to the general practitioner and lead to repeated prescriptions. Patients appreciate anti-hemorrhoidal treatments variably.

Low hemorrhoidopexy staple line does not improve results and increases risk for incontinence

BACKGROUND

The ability of stapled hemorrhoidopexy (SH) to cure hemorrhoidal symptoms appears to depend on patient characteristics and operative technique. We assessed the association between outcome of SH and patients' characteristics and procedure parameters (associated procedure, suture line height, doughnut size, presence of malpighian tissue or smooth muscle in specimen).

METHODS

A total of 68 consecutive patients (56 males) were prospectively operated by 3 different surgeons. Hemorrhoids were grade II (6%), grade III (76%) or grade IV (18%).

RESULTS

At a mean 32-week follow-up (range, 9-77), symptoms had resolved in 77% of patients, independently of any operative or clinical parameter. New onset anal incontinence occurred in 11 men (17%): all had urgency, with flatus and liquid stool incontinence in two, and flatus incontinence and mucus soiling in one. Univariate analysis revealed that persistent incontinence was associated with a staple line <6.5 mm from the dentate line, doughnut height <22 mm, and congestive external hemorrhoids; it was also operator dependent (p<0.05). At the 4-week follow-up, 19% of patients had persisting symptoms but only 8% had a demonstrable mucosal prolapse.

CONCLUSION

Although the success rate of SH may not be influenced by technical variations, risk for moderate incontinence is elevated when the stapled line is low.

Risk factors associated with hemorrhoidal symptoms in specialized consultation

Epidemiology and risk factors of hemorrhoidal disease are not well defined.

AIMS AND METHODS

Past history and events occurring during the last two weeks before a medical visit for acute hemorrhoidal symptoms were analyzed and compared with controls consulting for any other diagnosis without exclusion.

RESULTS

Among complete inquiries returned by 931 private gastroenterologists, files from 1033 patients (542 males) and 1028 controls (504 males) were randomly selected. Hemorrhoidal disease patients were younger (47 +/- 14.5 vs. 52 +/- 16.5 yrs; P<0.0001); sex ratio was not different from controls. Factors significantly associated with hemorrhoidal crisis were: past history of hemorrhoidal symptoms, age<50 yrs, past history of anal fissure, occupational activity (OR 5.17; 1.95; 1.72; 1.43; P<0.1) and recent unusual events: spicy diet, constipation, physical activity, alcohol intake (OR 4.95; 3.93; 2.79; 1.99; P<0.1). Stress protected against hemorrhoids (OR 0,49; P<0.0001). For women aged less than 40 yrs, no significant risk factor related with genital activity was found for hemorrhoidal disease.

CONCLUSION

For young patients, especially those with a past hemorrhoidal history, spice or alcohol intake and constipation are risk factors for hemorrhoidal crisis. For young women, prevention is essentially based on treatment of constipation associated with genito-obstetrical events.

[Postoperative pain and long-term results after hemorrhoidal treatment with anopexy]

AIMS

Anopexy allows treatment of hemorrhoidal symptoms with a less painful postoperative course. This information is important for the patient, but may lead to dissatisfaction if pain level is higher than expected. To evaluate perceived pain and physical limitation levels in relation to patient's expectation. Evaluate long-term functional results.

RESULTS

Sixty-eight consecutive patients (56 males) were prospectively included. Distribution of haemorrhoid grades were 4 grade 2 (6%), 52 grade 3 (76%) and 12 grade 4 (18%). Postoperative pain level was less or equal than expected for 85% of patients, with a better acceptance superior to 45 years. Physical limitation was equally or less important than expected for 89%. At the 32 weeks follow-up hemorrhoidal symptoms were present in 23%, uninfluenced by any patient's or operative characteristics. Incontinence with urgency was reported by 17%. Presence of an alliterated continence was linked to stapled line inferior to 6,5 mm from pectineate line, doughnut height inferior to 22 mm, external hemorrhoids and related to surgeon.

CONCLUSION

Pragmatic information, although vague, about postoperative pain does not expose to patient's dissatisfaction. Functional results are not influenced by technical variation. Continence alterations are not severe, but frequent when stapled line is too close from pectineate line.

Defecation disorders: a French population survey

PURPOSE

Despite frequent occurrence, functional defecation disorders and related conditions have been infrequently reported in population studies. This study was designed to assess symptoms, lifestyle-behavioral changes, and medical care seeking related to functional defecation disorders in a large household community survey.

METHODS

A large household community survey was conducted in 10,000 individuals aged 15 years or older. A mailed questionnaire was used to assess ten common anorectal complaints; frequency, association, impact on quality of life, and medical care seeking were quantified.

RESULTS

Evaluation was obtained in 7,196 patients (3,455 males). During the previous 12-month period, 2,097 patients (29.1 percent) experienced functional defecation disorders: outlet constipation and fecal incontinence were reported in 22.4 and 16.8 percent respectively. Compared with patients with no anorectal complaint, patients with functional defecation disorders had a different gender status (females, 63.3 vs. 47.6 percent; P<0.01). Based on symptom severity, functional defecation disorders were perceived as the main anorectal complaint in 1,192 patients. In this group, emptying difficulties, unsatisfied defecation, gas, and fecal incontinence occurred at least once per month in 71.6, 56.1, 77.9, and 49 percent respectively: 66.6 percent with outlet constipation and 85.6 percent with incontinence revealed impairment in quality of life. Incontinent patients more frequently avoided medical care than those complaining of outlet constipation (67.4 vs. 46.4 percent; P<0.01).

CONCLUSIONS

Functional defecation disorders concerns at least one of four French individuals. Outlet constipation and fecal incontinence frequently occur in association. Despite a low rate of patients seeking care, symptoms often are severe and related to quality of life impairment.

Cellulite nécrosante périnéale révélant un adénocarcinome rectal

We report one case of rectal cancer disclosed by a perineal cellulitis in a diabetic woman. This infrequent association has a bad prognosis. Diagnosis is mainly clinical. Treatment is urgent with large spectrum antibiotic therapy, surgical debridement, colostomy and hyperbaric oxygen if available. Surgical treatment of the rectal cancer can be done immediately or delayed.

[Pudendal hernia of the labia]

A case of hernia is reported with a brief review of perineal hernia.

Local excision of large rectal villous adenomas: long-term results

PURPOSE

Transanal excision of rectal villous adenomas is a widely used surgical technique, because it is a one-step procedure, requiring no sophisticated instrumentation, and allowing complete histologic analysis of the excised tumor. Therefore, it ranks alongside radical surgery and palliative destructive procedures, but its results are highly variable in the published series. This discrepancy may be explained by the variable completeness of tumor excision because of potential dissection difficulties. Because intraoperative exposure may be a major limiting factor, one of us (JF) has developed a tractable cutaneomucous flap procedure to lower the rectal tumor to the anal verge, where control of the dissection line is easier. This retrospective review of consecutive patients operated on during ten-year period reports long-term results after transanal excision for large rectal villous adenomas with the tractable flap technique.

PATIENTS

From 1978 to 1988, 207 consecutive patients (100 males), mean age 68 (range, 24-90) years, were operated on for an apparently benign villous rectal adenoma. Twenty-one patients (10 percent) were referred after failure of previous treatments: 11 endoscopic, 8 surgical, 1 laser, 1 radiotherapy. Mean distance of lower tumor edge from anal margin was 5.6 (range, 0-13) cm and was <10 cm in 82 percent.

RESULTS

Three patients (1.5 percent), including one with a Tis carcinoma, underwent a secondary treatment for immediate gross failure of resection: one further local excision and two palliative laser destructions. Immediate postoperative course was uneventful for 96 percent; there was one death from perineal gangrenous infection, four cases of hemorrhage, and three urinary retentions. Subsequently one case of transient fecal incontinence and 11 medically managed stenoses were noted. Mean size of resected tumor was 5.4 (range, 1-17) cm. Deep excision margins concerned the rectal muscular layers in 199 patients (96 percent) and perirectal fat in 8 (4 percent). Specimen margins were negative for cancer in 175 (85 percent) and positive or unknown in 32 cases. Histologic evaluation demonstrated in situ cancer in 28 (14 percent) and invasive carcinoma in 9 (4 percent). In three patients (1 percent), two abdominoperineal resections were immediately performed (one T2 with a mucinous contingent, one T3) and one adjuvant radiotherapy (one undifferentiated T2). Four patients (2 percent) did not return for postoperative evaluation. For the remaining 198 patients, mean follow-up was 74 +/- 34 (median, 75; range, 1-168) months. Forty-four died from unrelated causes. Recurrence occurred in seven (3.6 percent) and was malignant in two, who subsequently died. Specific recurrence-free probability was 99.5 percent at one year, 96 percent at five years, and 95 percent at ten years. A lesion size >6 cm (10 vs. 1 percent for smaller tumors) and the presence of an invasive carcinoma (20 vs. 3 percent without invasive carcinoma) were significantly associated with an increased probability of recurrence at five years.

CONCLUSION

Providing that adequate intraoperative exposure is obtained and advanced malignant tumors receive immediate secondary treatment, transanal resection of clinically benign, large rectal villous adenomas is safe and effective. It is an alternative to rectal resection, which exposes the patient to potentially adverse effects, and also to destructive procedures, which preclude any histologic evaluation of the tumor.

Lack of effficacy of botulinum toxin in chronic anal fissure

BACKGROUND AND AIM

Hypertonicity of internal anal sphincter plays a major role in the persistence of chronic anal fissure. Botulinum toxin could induce internal anal sphincter relaxation without the adverse effects of surgery (long-term faecal incontinence) or topical nitrates (anal burning, headaches, hypotension).

METHODS

We conducted a placebo-controlled, randomised, double-blind study to assess the efficacy of a single injection of botulinum toxin in the internal anal sphincter of patients with chronic anal fissure in six ambulatory care clinics. Eligibility criteria included a mean value of post-defecation anal pain >or= 30 mm on a 100 mm visual analogue scale over the week preceding inclusion. Main endpoint was the proportion of patients with symptomatic improvement during the fourth week after inclusion (post-defecation anal pain below 10 mm).

RESULTS

Forty-four patients (22 in each group) were included. At inclusion, there was no significant difference between groups on age, sex ratio, pain duration, post-defecation anal pain, analgesic consumption and stool frequency. Ten (45%) and 11 (50%) patients reported symptomatic improvement on the main endpoint (P=0.76) in placebo and botulinum toxin groups, respectively. Ten patients (five in each group) had healed fissure at week 4 and ten patients (five in each group) required surgical treatment between weeks 4 and 12. Similarly, there was no significant difference between groups on other variables between weeks 4 and 12.

CONCLUSIONS

The efficacy of a single injection of botulinum toxin in the internal anal sphincter does not differ from that of a placebo in patients with chronic anal fissure.

[Local excision with postoperative radiotherapy for T2 or T3 distal rectal cancer. Long-term results]

STUDY AIM

To evaluate, in a prospective study of a cohort of patients, the local recurrence rate of T2 or T3 rectal cancers treated by transanal excision after preoperative irradiation.

PATIENTS AND METHODS

Between 1992 and 1999, 34 patients were treated after radiotherapy by a local excision for a distal rectal carcinoma limited to (stage T2) or invading through the muscular layer (stage T3). Four patients were excluded either for palliative treatment or lost for follow-up. Thirty patients were included in the study (8 uT2, 8 uT3, 14 undetermined preirradiation stage).

RESULTS

After a 74-month mean follow-up (median: 46), the 5-year local recurrence rate was 33%. Even among subgroups of patients with a significant risk factor for local recurrence (size > 40 mm, clear margin < 2 mm, uT3 stage versus uT2) there were no benefits from irradiation.

CONCLUSION

Local excision of T2 or T3 rectal cancers is associated with an elevated local recurrence rate. This result is demonstrated even after adjunction of a preoperative irradiation. So, local treatment must be restricted to clearly informed patients who definitively refuse a radical intervention.

[Quality of life, symptoms of dyschezia, and anatomy after correction of rectal motility disorder]

AIM OF THE STUDY

To evaluate the quality of life of patients suffering from dyschezia and its correlation with symptomatic complaints and anatomical abnormalities, before and after elective surgery for rectal static disorder.

PATIENTS AND METHODS

A prospective study was conducted using a general quality of life questionnaire (SF36) and a constipation specific score (PAC-QoL), a dyschezia symptom score, and defecography.

RESULTS

Thirty-eight female dyschesic patients (mean age 54 years) underwent surgery for rectocele with (n=16) or without (n=14) internal rectal prolapse, an isolated internal rectal prolapse (n=3), or a total rectal prolapse (n=5). Preoperative quality of life was low, correlated with the intensity of dyschezia. Seven months after surgery, quality of life and dyschezia improved independently of the amplitude of the anatomical correction. More items improved in the constipation specific score than on the quality of life questionnaire; they were correlated with the course of dyschezia symptoms. Neither incontinence nor irritable bowel syndrome affected evolution of the symptoms.

CONCLUSION

Surgery improved initially low quality of life and symptomatic complaints in patients with dyschezia and a rectal static disorder, independently of anatomic repair. Differences in changes observed in the PAC-QoL and SF36 suggest different fields of application.

[Hemorrhoids and hemorrhoidal disorders]

Haemorrhoids are normal anatomic components of the anal canal, involved in the fine adjustment of continence. This physiological role requires normal size and location. The anatomical aspects of haemorrhoids do not reflect their symptomatic expression. Natural evolution of haemorrhoids is benign, but most often chronic, with spontaneous worsening. Despite recent advances in medical and instrumental treatments, about 10% of the patients need a radical and definitive treatment relying on surgery. This comfort-oriented surgery should only be proposed to handicapped patients, after information about the rare (but possible) complications and the unavoidable transitory postoperative discomfort.

Transanal electroresection of small rectal cancer: a sole treatment?

PURPOSE

Because abdominoperineal resection is associated with high morbidity and mortality, there is interest in local treatment of distal rectal carcinoma. Our technique of transanal electroresection ensures full-thickness tumor excision and complete histopathologic examination.

METHODS

From July 1983 to July 1990, 227 patients underwent surgery. Criteria for cure were no extramural invasion (61 exclusions) and negative margins (34 exclusions). Six patients underwent postoperative radiotherapy and, therefore, were excluded.

RESULTS

Among those included were 126 patients (66 men), who had a mean age of 68 +/- 11 (median, 68) years. Median tumor size was 35 mm. Distance from anal verge was less than 6 cm for 68 percent and 6-10 cm for 30 percent of patients. Deepest layer invaded was as follows: submucosa (T1), 35 percent; inner muscular layer (T2a), 42 percent; outer muscular layer (T2b), 23 percent. There was one postoperative death. Immediate postoperative course was uneventful for 94 percent of patients; at long-term, five cases of incontinence and two stenoses were noted (6 patients). Median follow-up was 88 (1-137) months. Global survival was 71 and 46 percent, and cancer-specific survival was 85 and 81 percent at 5 and 10 years, respectively. Of 35 patients (28 percent) with recurrence, 24 were treated. Global survival after recurrence was 72 and 50 percent at one and two years, respectively. The only pejorative prognostic factors isolated for survival or recurrence were mucinous contingent and intratumoral vascular invasion.

CONCLUSION

Results of local treatment for rectal carcinoma in selected patients are favorable (5-year specific survival, 85 percent). Decisive prognostic factors are seldom isolated, but some patients would benefit from adjuvant therapy.

Low bone mineral density in patients with inflammatory bowel disease

To assess the prevalence and risk factors for low bone mineral density in inflammatory bowel disease, we studied 61 consecutive patients, mean age 36 +/- 11 years. Twenty-seven had a Crohn's disease and 34 ulcerative colitis (including 13 with ileoanal anastomosis). Three patients, two women and one man (32, 70, and 45 years old, respectively) had vertebral crush fractures. Bone mineral density measured by dual energy x-ray absorptiometry at spine and femoral level was more than 2 SD below normal values in 23% of the patients, all of them having received steroid therapy. Eighteen patients (29%) had never received steroid therapy; their bone mineral density was not different than those who had. Univariate analysis showed a positive correlation between bone mineral density and body weight or oral calcium intakes, and a negative correlation with steroid daily dose. After ileoanal anastomosis, bone mineral density was not different from other groups and showed a positive correlation with time elapsed since coloproctectomy. We concluded that bone mineral density is low in patients with inflammatory bowel disease and exposes them to the risk of bone fracture. Bone mineral density after ileoanal anastomosis may increase with time after surgery.

Human papillomavirus infection in esophageal squamous-cell carcinoma in western countries

Recent studies have suggested that esophageal HPV infection could be a risk factor for esophageal squamous-cell carcinoma. The aims of our study were to assess the presence of HPV esophageal infection among French patients with esophageal squamous-cell carcinoma and to compare the prevalence of this infection among control patients exposed to similar known risk factors (alcohol and tobacco) and among non-exposed control patients. All patients had the following investigations: serum immunoglobulin level, T-lymphocyte subsets, cutaneous anergy test and endoscopy with biopsies from tumoral and normal areas. Three different methods were used for HPV-infection diagnosis: histological score, in situ hybridization intended for detection of HPV types 6, 11, 16, 18, 31 and 33, and dot blot intended for detection of HPV types 6/11 and 16/18. Five out of 12 patients with esophageal carcinoma had HPV esophageal infection. This infection did not result from impaired immune status. The most frequently observed types are HPV 16/18. None out of 17 exposed controls and only 1 out of 7 nonexposed controls had HPV esophageal infection (p less than 0.01). HPV infection may be implicated in the development of esophageal squamous-cell carcinoma in association with known risk factors.

Intestinal absorption of free oral hyperalimentation in the very short bowel syndrome

Ten adult ambulatory patients with the nonactive digestive disease short bowel syndrome were prospectively studied to quantitatively assess their free oral intake and their net digestive absorption of total calories, fat, protein, and carbohydrate during a 3-day period at least 6 months after a resection. The remaining portions of small bowel had a mean length of 75 cm (range, 0-200 cm); the remaining colon lengths had a mean of 67% of normal (range, 0%-100%). The experimental diets were formulated according to a home dietary inquiry. During the study period, pooled intakes and digestive losses were measured for total calories, fat, and protein using the bomb calorimetry, Van de Kamer, and Kjeldahl techniques, respectively. The ingested diet provided 58 +/- 14 kcal.kg-1.day-1 (mean +/- SD) and consisted of 46% carbohydrate, 31% fat, and 23% protein. Net digestive absorption was 67% +/- 12% for total calories, 79% +/- 15% for carbohydrate, 52% +/- 16% for fat, and 61% +/- 19% for protein. The larger net digestive absorption of carbohydrate (P less than or equal to 0.004) compared with fat and protein suggests salvage of colonic cholesterol in short bowel syndrome patients. It is concluded that these patients with the short bowel syndrome adapted to a hypercaloric, hyperprotein diet to compensate for increased fecal losses and that this hyperphagia does not seem to have impaired their net digestive absorption.
