Abstract
PURPOSE While acute anal fissures can be treated with topical therapy to reduce sphincter hypertonia (e.g., isosorbide dinitrate, glyceryl trinitrate, diltiazem), chronic fissures may require more invasive instrumental therapy. Currently, the golden standard remains lateral internal sphincterotomy; however, this carries the long-term risk of faecal incontinence. Fissurectomy can be a valuable alternative, but is less efficient because of absence of correction of underlying hypertonia. In this study, we aim to evaluate the additional effect of injection of botulinum toxin during fissurectomy in the treatment of chronic anal fissures. METHODS A single-centre retrospective analysis of 293 isolated superficial fissurectomies with or without injection of botulinum toxin was performed, with pain relief as primary endpoint. RESULTS The majority of patients undergoing fissurectomy were women (65%, mean age 45.0 years vs. 35% men, mean age 48.3 years), often because of ventral fissures (30% in women vs. 8% in men). Fissurectomy resulted in resolution of complaints in 81.1%, while additional injection of botulinum toxin resulted in resolution in 90.1% (p < 0.05). Complication rate was identical between the two groups, mainly (flatus) incontinence (4.5% vs 4.9% with botulinum toxin) and post-operative bleeding (1.8% vs 2.5% with botulinum toxin). CONCLUSION Injection of botulinum toxin significantly increases the efficiency of fissurectomy in the treatment of chronic anal fissures without additional complications.

Abstract
PURPOSE Injection of botulinum toxin into the internal anal sphincter is a well-documented intervention to reduce anal hypertonia in the treatment of anal fissures. In patients receiving chemotherapy, painful anal conditions are frequent, secondary to change in bowel habits and reduced immunity. However, injection of botulinum toxin is often not offered due to fear of complications. METHODS In this retrospective longitudinal observational study, performed in a tertiary hospital setting, we analysed patient characteristics, outcome and complication rates of botulinum toxin injection in patients actively receiving chemotherapy. RESULTS Twenty-six patients were treated with 20-50 IU botulinum toxin while actively receiving chemotherapy because of intractable pain and hypertonia. The fissure was located dorsally in 69% (n = 18) and ventrally in 19% (n = 5), while in 3 patients (12%), no fissure was documented. The majority of the patients (88%, n = 23) had complete (54%, n = 14) or partial (35%, n = 9) relief of pain. In three patients, additional anal pathology developed in the weeks following botulinum toxin injection: thrombosis of grade IV haemorrhoids, perianal haematoma and an intersphincteric abscess. CONCLUSIONS Injection of botulinum toxin in the anal sphincters is a safe and effective analgesic option in patients with anal fissure while actively receiving chemotherapy.

Abstract
BACKGROUND To improve detection of mucosal lesions during colonoscopy a number of imaging modalities have been suggested, including high definition and virtual chromoendoscopy. Given the theoretical advantage of these new imaging techniques, we aimed to investigate their use for the detection of polyps in patients referred for colonoscopy in a large tertiary hospital. METHODS Demographic, endoscopic, and histological data from 1855 consecutive patients undergoing colonoscopy were collected prospectively. Patients were randomly assigned to three endoscopy systems (Fujinon, Olympus, or Pentax) in combination with four modalities: conventional white-light colonoscopy (n = 505), high definition white-light colonoscopy (n = 582), virtual chromoendoscopy (n = 285) and high definition virtual chromoendoscopy (n = 483). RESULTS The mean adenoma detection rate (ADR) was 34.9 %, and the adenoma per colonoscopy rate (APCR) was 2.1. No significant differences were noted between the three endoscopy systems. Moreover, no differences in ADR or APCR were observed between the four imaging modalities. High definition white-light colonoscopy resulted in a significantly higher detection of sessile serrated adenomas (8.2 % vs. 3.8 %; P < 0.01) and adenocarcinomas (2.6 % vs. 0.5 %; P < 0.05) compared with the conventional procedure. CONCLUSIONS No significant differences in ADR or APCR between different endoscopy systems, high definition, and/or virtual chromoendoscopy could be observed in routine colonoscopies in the general population. High definition endoscopy was associated with a significantly higher detection rate of serrated adenomas and adenocarcinomas.

Abstract
BACKGROUND Endoscopic resection (ER) with or without ablation is the first choice treatment for early Barrett's neoplasia. Adequate staging is important to assure a good oncological outcome. OBJECTIVE The purpose of this study was to investigate the diagnostic accuracy of pre-operative biopsies in patients who undergo ER for high-grade dysplasia (HGD) or early adenocarcinoma (EAC) in Barrett's oesophagus (BE) and the cardia. METHODS Between November 2005-May 2012, 142 ERs performed in 137 patients were obtained. Worst pre-ER and ER histology were compared. Upgrading/downgrading was defined as any more/less severe histological grading on the ER specimen. RESULTS The accuracy of pre-ER biopsies in predicting final histology was 61%. ER changed the pre-treatment diagnosis in 55 of the 142 procedures (39%) with downgrading in 23 cases (16%) and upgrading from HGD to T1a or T1b in 32 cases (23%). In the majority of upgraded cases, a visible lesion according to the Paris classification could be detected (26/32, 81%). CONCLUSION The diagnostic accuracy of oesophageal biopsies alone in predicting final pathology in Barrett's dysplasia is only 61%. The majority of upgraded lesions are detectable. When ablative therapy is considered in HGD Barrett's dysplasia a meticulous inspection for and removal of all small visible lesions is mandatory.

Abstract
Laparoscopy offers great exposure and surgical detail, reduces blood loss and the need for excessive abdominal packing and bowel manipulation making it an excellent modality to perform pelvic floor surgery. Laparoscopic repair of level I or apical vaginal prolapse may be challenging, due to the need for extensive dissection and advanced suturing skills. However it offers the efficacy of open abdominal sacrocolpopexy, such as lower recurrence rates and less dyspareunia than sacrospinous fixation, as well as the reduced morbidity of a laparoscopic approach.

Abstract
Introduction: Chronic constipation is a common condition that is difficult to treat. Existing options for the treatment of patients with different subgroups of constipation are limited. A new efficacious and safe drug is needed to limit the frequently observed adverse effects induced by laxatives, to improve general wellbeing and quality of life, and to provide an alternative for enemas or even resectional surgery in patients in whom stimulant laxatives cause disabling adverse effects or fail to increase bowel movement frequency. Aims: The purpose of this article is to assess the current evidence supporting the use of the selective and high affinity serotonin-4 (5-HT4) receptor agonist prucalopride in the management of chronic constipation. Evidence review: There are now convincing data from phase II and multicenter phase III randomized, double-blind, placebo-controlled trials that prucalopride treatment results in a clinically meaningful increase in the number of spontaneous complete bowel movements, a reduction of perceived severity of symptoms and improved disease-related quality of life in a significant proportion of patients. There is a rapid onset of the effect and the improvement is maintained for at least 12 weeks. Prucalopride in a dose of up to 4 mg per day appeared generally well tolerated and devoid of serious cardiac events. Adverse events, most frequently headache and nausea, are usually mild or moderate and occur mainly during the first days of treatment. Prucalopride should be used with prudence and with careful assessment of the benefit-risk ratio until more clinical and electrophysiologic data become available, because relatively few patients have been exposed to the drug for long periods of time. Place in therapy: Prucalopride 1–2 mg once daily may be given to patients suffering from chronic constipation for whom laxatives do not provide adequate relief of their symptoms. Patients with severe constipation and slow transit, who frequently develop tolerance to stimulant laxatives, are also eligible for prucalopride treatment.

Abstract
AIMS We studied the long-term anatomical and functional outcome following sacrocolpopexy for apical vaginal prolapse using xenogenic grafts in a population at increased risk for graft-related complications (GRCs). METHODS Twenty-two consecutive patients with symptomatic apical prolapse were scheduled for laparoscopic sacrocolpopexy (LSC) with porcine grafts because they were presumed to be at risk for GRC, because of pre-existing vaginal ulcerations (n = 4), concomitant vaginal prolapse repair (n = 15), total hysterectomy (n = 1), or intra-operative abdominal contamination due to accidental laceration of the vagina, bowel perforation (n = 1) or the presence of infection (n = 1). Either small intestinal submucosa (n = 8) or dermal collagen (n = 14) was used. Outcome measures were GRCs, anatomical cure (<or=Stage I at any compartment), subjective cure, impact on bowel, bladder, and sexual function measured by a standardized interview. RESULTS At study closure 20 (91%) patients were available for functional evaluation and 16 (73%) for anatomical evaluation at a mean follow-up period of 27.4 months. The GRC rate was 25% (n = 4) prompting reintervention in half, and including two patients with spondylodiscitis. The anatomical cure rate was 31.5%. Failures at the vault, anterior, and posterior compartments occurred in, respectively, 31%, 18.8%, and 50% of patients. The subjective cure rate was 60% and three patients (15%) underwent redo-LSC. CONCLUSION The strategy of using xenografts in patients at risk for GRC, did not prevent these to occur and was associated with a high anatomical and functional failure rate as well as reoperation rate.

Abstract
BACKGROUND Endoscopic dilatation of Crohn's disease-related strictures is an alternative to surgical resection in selected patients. The influence of disease activity and concomitant medical therapy on long-term outcomes is largely unknown. AIM AND METHODS To study the long-term safety and efficacy of stricture dilatation in a single centre cohort. RESULTS Between 1995 and 2006, 237 dilatations where performed in 138 patients (mean age 50.6+/-13.4, 56% female) for a clinically obstructive stricture (<5 cm, 84% anastomotic). Immediate success of a first dilatation was 97% with a 5% serious complication rate. After a median follow-up of 5.8 years (IQR 3.0-8.4), recurrent obstructive symptoms led to a new dilatation in 46% or surgery in 24%. Niether elevated levels of C-reactive protein nor endoscopic disease activity predicted the need for new intervention. None of the concomitant therapies influenced the outcome. CONCLUSION This largest series ever reported confirms that long term efficacy of endoscopic dilatation of Crohn's disease outweighs the complication risk. Neither active disease at the time of dilatation nor medical therapy afterwards predict recurrent dilatation or surgery.

Abstract
BACKGROUND This study examined the outcome of surgery for symptomatic Crohn's rectovaginal fistula (RVF) and assessed the effect of therapy with antibody against tumour necrosis factor (TNF) on healing. METHODS Fifty-six patients with Crohn's disease underwent surgery for a RVF between January 1993 and December 2006. Outcome analysis was performed in February 2008 in relation to the surgical procedures used and the effect of anti-TNF treatment. RESULTS Four patients with a healed fistula still had a stoma at final follow-up for other reasons and were excluded from the analysis. Fistula closure was achieved in 81 per cent of the remaining 52 patients. Primary and secondary surgical success rates were 56 and 57 per cent respectively. The primary healing rate was similar in patients who received anti-TNF treatment before the first operation (12 of 18 patients) and those who did not (19 of 34). In univariable analysis, duration of Crohn's disease (P = 0.037) and previous extended colonic resection (P < 0.001) were significantly related to failure of primary surgery, but only the latter remained significant in multivariable analysis (P < 0.001). Late recurrence developed in four patients. CONCLUSION Fistula closure was achieved in most patients, but more than one operation was often required.

Abstract
PURPOSE We compared the medium term anatomical and subjective outcome, and graft related complications after sacrocolpopexy for apical vaginal prolapse using xenogenic or polypropylene grafts. MATERIALS AND METHODS We prospectively studied 50 consecutive patients who underwent laparoscopic sacrocolpopexy with porcine grafts of small intestinal submucosa (21) or dermal collagen (29). We compared these patients to 100 consecutive controls in whom polypropylene was used, and underwent surgery before (50) or after (50) the cases. The primary outcome was anatomical cure (stage I or less at any compartment). Secondary outcomes were graft related complications, subjective cure and quality of life evaluated by clinical examination, standardized interview and prolapse specific questionnaire, respectively. RESULTS At study closure 129 (86%) patients were available for functional evaluation and 104 (67%) were available for anatomical evaluation. Mean postoperative followup (+/-33 months) and baseline characteristics except age were comparable. The overall anatomical failure rate was comparable (49% vs 34%, p = 0.053) but failures at the vault (21% vs 3%, p <0.01) and posterior compartment (36% vs 19%, p <0.05) were more frequent in the xenograft group. There were 6 reoperations including secondary laparoscopic sacrocolpopexy (5) and cystocele repair (1), all confined to the xenograft group (p <0.01). Graft related complications were equally frequent (11%) in the xenograft and polypropylene groups. The reoperation rate for graft related complications was not different (xenograft 3% vs controls 11%, p = 0.20). There were no differences in functional outcome and quality of life between xenografts and controls. CONCLUSIONS While overall anatomical failure was comparable, sacrocolpopexy using xenograft was associated with more apical failures and reoperations for prolapse than with polypropylene without differences in functional outcome. The use of xenografts did not decrease the number of graft related complications.

Abstract
BACKGROUND Cidofovir, a nucleotide analog with antiviral activity against a broad range of DNA viruses including human papilloma viruses (HPV), is available off label to clinicians. OBJECTIVE To provide a better knowledge of pharmacology and effects when topically applied. METHODS After reviewing the chemistry, physiology, and animal studies, an overview of clinical studies is provided. RESULTS/CONCLUSIONS Cidofovir, as a result of its antiviral and antiproliferative activity and its ability to induce apoptosis, can offer a solution for the treatment of severe recurrent HPV-induced lesions. It can also be used to attempt to treat dysplastic lesions and as an adjuvant treatment. The long-lasting antiviral activity allows infrequent dosing. As a rule, cidofovir applied on the skin is well tolerated, even in long-term treatment. The dose-limiting nephrotoxicity of the drug is not a concern in patients with a glomerular filtration rate within the normal range. Cidofovir has clearly influenced the landscape of refractory and dysplastic anogenital condylomata acuminata and its use has increased over the last decade. However, further controlled clinical trials are needed to assess the role of cidofovir and its derivatives.

Abstract
BACKGROUND Limited prospective data on the anatomic and functional outcome after laparoscopic sacrocolpopexy (LSC) are available in the literature. OBJECTIVE To describe the medium-term anatomic and functional outcome of LSC. DESIGN, SETTING, AND PARTICIPANTS Prospective consecutive series of 132 women with vaginal vault prolapse undergoing LSC between 2001 and 2006, which was after our learning curve. Patients with urodynamically proven stress incontinence (SI) underwent a concomitant tension-free vaginal tape (TVT) procedure. INTERVENTION Patients underwent LSC with a polypropylene implant. MEASUREMENTS Principal outcome measures were anatomic cure (stage 1 or lower) assessed by the Pelvic Organ Prolapse Quantification (POPQ) system and subjective cure and impact on quality of life measured by a standardised interview and, since its introduction in 2004, by a prolapse-specific quality-of-life questionnaire (P-QOL). RESULTS AND LIMITATIONS At a mean follow-up of 12.5 mo, the anatomic cure rate for the apex was 98%. Anatomic failures elsewhere were mainly at the posterior compartment (18%). Subjective prolapse cure rate was 91.7%, and no patients required reoperation for recurrent prolapse. Symptoms of preoperative SI, urge incontinence, or constipation were cured in 43%, 46%, and 42% of patients, respectively. The rate of de novo SI was 7.3%. De novo constipation developed in 5% and de novo dyspareunia developed in 19%. Patients' quality of life improved significantly. Erosions occurred in 4.5%, all within 1 yr. A limitation of the study is that the quality-of-life assessment score became available halfway through the study, limiting the number of preoperative observations (n=36). CONCLUSIONS We demonstrated that LSC results in good anatomic outcome and subjective cure of prolapse symptoms at medium term. The posterior compartment was most vulnerable for recurrence.

Abstract
We report a case of uterine prolapse in a young woman, treated by posterior intravaginal slingplasty with preservation of the uterus as a feasible and safe surgical procedure. Posterior intravaginal slingplasty is commonly used to correct vaginal vault prolapse, but may be a valuable alternative to correct uterine prolapse. We compare this technique to other techniques to correct uterine prolapse.

Abstract
Guidelines for the treatment of anal fissure have been published in the USA and UK but differ. Many centers follow guidelines based on local experience. In December 2005, we met with the aim of developing an evidence-based treatment algorithm for anal fissure, applicable to both primary and secondary care. This algorithm may rationalize the treatment of anal fissure in primary and secondary care settings.

Abstract
Primary perianal actinomycosis is rare. Sporadic cases, with lesions varying in extent have been reported. The infection is caused by the bacterium Actinomyces, which often is a saprophyte. Male gender and diabetes are risk factors, but the exact pathogenic mechanism remains speculative. The diagnosis is a challenge and often delayed, with a protracted history of masses and sinuses extending into the gluteal and genital region. The treatment, a combination of surgery and antibiotics, is poorly standardized. We report three cases and compare their characteristics to those of published cases, found by a computerized literature search (1968-2002). The lesions, a simple fistula-in-ano or a mass, were diagnosed in an early stage in all three patients. The infection always spread into the scrotum. There were no risk factors other than gender, except in one patient. The diagnosis was suspected by the observation of draining sulfur granules and promptly confirmed by histology in the three cases. All patients healed with antibiotics in addition to simple surgical procedures. Treatment consisted of amoxicillin for two weeks in two cases and more extended antimicrobial treatment in the third. These findings are contrasting with the classic picture of perianal actinomycosis. It is concluded that perianal actinomycosis can occur in the absence of risk factors and that early diagnosis requires a high degree of suspicion. An infection with Actinomyces should be suspected in the presence of lesions containing watery purulent material with sulfur granules. The indication for extended antibiotherapy combined with sphincter damaging surgery may need to be revised in the presence of early detection.

Abstract
BACKGROUND Polyethylene glycol 3350 increases stool frequency and accelerates colonic transit. Used as a laxative, it proved effective in patients with normal and slow transit. Although free of severe side effects, it may cause nausea and vomiting. The effect of this substance on upper gut transit has not been studied. AIM To investigate the effect of polyethylene glycol 3350 on gastric emptying and oro-caecal transit in 12 healthy subjects. METHODS In a randomised controlled study, isosmotic polyethylene glycol 3350 electrolyte balanced solution, in the maximal recommended dose or isosmotic electrolyte solution, was administered after breakfast and lunch on separate days. Gastric half-emptying time and oro-caecal transit time were measured using [13C]-octanoate and lactose-[13C] ureide breath tests. RESULTS Isosmotic polyethylene glycol 3350 electrolyte solution, as compared to isosmotic electrolyte solution, decreased oro-caecal transit time from 424+/-28 to 314+/-17 min (P = 0.001). Gastric half-emptying time was significantly increased (84+/-6 min versus 127+/-14 min; P = 0.006). CONCLUSION Polyethylene glycol 3350 accelerate oro-caecal transit in healthy subjects, but also cause an important delay in gastric emptying. The delay in gastric emptying may be of clinical significance in patients who have associated gastroparesis.

Abstract
Patients with slow transit constipation frequently have delayed gastric emptying. In animals rectal distensions inhibit gastrointestinal motility. In healthy volunteers isovolumetric rectal distensions delay upper gut transit. The purpose of this study was to determine the effect of continuous isobaric rectal distension on gastric emptying and oro-cecal transit in young females. Using validated 13C octanoic and lactose-[13C] ureide breath tests gastric half-emptying time and oro-cecal transit time for a meal were measured in 12 volunteers. The tests were repeated in randomized order: during isobaric balloon distension and during sham distension. Isobaric rectal distension was applied using a polyethylene bag connected to a barostat. Intraballoon pressure was kept just below the threshold for the urge sensation. Mean gastric half-emptying time during rectal distension (92.3 +/-5.1 min) was significantly higher than during sham distension (78.8 +/- 4 min; P = 0.015). Mean oro-cecal transit time during rectal distension (391.3 +/-29.1 min) and sham distension (328.8 +/- 38.4 min) were not significantly different. In conclusion, these findings indicate that isobaric rectal distension inhibits gastric emptying, but not small bowel transit in young healthy women. Studies in patients with constipation are indicated.

Abstract
BACKGROUND Different food items are made responsible for irritable bowel syndrome (IBS) symptoms, but the physiopathology of IBS remains unclear. AIMS During a meeting in Nice, France, experts of the European Working Team of the IBiS Club discussed selected data regarding the relationships between alimentation, food items (including fibers) and IBS symptoms. METHODS/RESULTS Food allergy remains a difficult diagnosis, but medical and general history, presence of general symptoms such as skin rash, and hypersensitivity tests may help in achieving a positive diagnosis. On the other hand, food intolerance is more confusing because of the subjectivity of the relationship between ingestion of certain foods and the appearance of clinical symptoms. Different food items which are commonly implicated in adverse reactions mimicking IBS were found to be stimulants for the gut, suggesting that patients with predominant diarrhea IBS have to be carefully questioned about consumption of different kinds of food (i.e., coffee, alcohol, chewing gum, soft drinks) and not only on lactose ingestion. Gas production is discussed on the basis of retention of intestinal gas as well as on malabsorption of fermentable substrates. The role of a large amount of this kind of substrate reaching the colon is suggested as a potential mechanism of IBS-type symptoms in overeating patients. Regarding the role of fiber in IBS, the expert group concluded that fibers are not inert substances and that they could trigger pain or bloating in some IBS patients. CONCLUSION Despite numerous reviews on this subject, it is very difficult to give general dietary advice to IBS patients, but dieteticians may have a positive role in managing such patients.

Abstract
OBJECTIVES The complexity of anal fistulas is different in patients with and without Crohn's disease and in men and women. This may affect the localization of the internal orifice. We compared the characteristics of anal fistulas and the accuracy of Goodsall's rule in predicting the position of the internal orifice in male and female Crohn's and non-Crohn's patients. METHODS A total of 191 fistula tracks in 182 consecutive patients (110 men and 72 women) were analyzed prospectively. Of the patients, 63 were diagnosed with Crohn's disease. The positions of the orifices were recorded and the accuracy of Goodsall's rule determined. RESULTS The distribution of fistula subtypes among Crohn's and non-Crohn's patients differed significantly (p = 0.0471). Fistulas with an anterior external opening occurred more frequently in Crohn's patients (p = 0.0350) and in women (p = 0.0030). Fistulas with a posterior external orifice were observed more frequently in non-Crohn's patients (p = 0.0350) and in men (p = 0.0028). Overall, Goodsall's rule performed less well in women compared with men (p = 0.0633). The accuracy of Goodsall's rule overall was not affected by Crohn's disease. In female non-Crohn's patients, the positive predictive value of a posterior external orifice was lower than in men (p = 0.0406). CONCLUSIONS The distribution of fistula subtypes and the ratio of anterior and posterior external openings among Crohn's and non-Crohn's patients differ significantly. Many fistulas defy Goodsall's rule, particularly in women and when applied to fistulas with anterior external orifices. The popular rule, however, falls equally short in Crohn's and non-Crohn's fistulas.

Abstract
BACKGROUND Chronic constipation (CC) is common and there is a need for more effective and better-tolerated agents that normalize bowel function without affecting secretion. Prucalopride is a novel, selective serotonin(4) receptor agonist with enterokinetic properties. AIMS Pilot study to compare the efficacy and tolerability of prucalopride and placebo in patients with severe CC referred to a tertiary centre. METHODS After 4-weeks' run in, patients were randomized to 4 weeks' once daily, double-blind treatment with either prucalopride 4 mg (n = 27) or placebo (n = 26). A 50% dose reduction after 2 weeks' treatment was possible for patients with an excessive gastrointestinal response to the study medication (severe cramps, abdominal pain, and diarrhea). Patients assessed efficacy using a visual analogue scale (VAS) and recorded bowel function in daily diaries. The investigator assessed efficacy and total gut transit time (marker study). RESULTS Patient VAS assessment demonstrated that prucalopride was significantly more effective than placebo in softening stools, and decreasing straining and time to first stool. Prucalopride also had a positive effect on stool frequency, feeling of complete evacuation and total gut transit time, although these differences were not statistically significant compared with placebo. The most common adverse events were gastrointestinal symptoms and headache; most were mild to moderate. There were no clinically relevant effects on cardiovascular or laboratory parameters. CONCLUSIONS Once-daily prucalopride 4 mg for 4 weeks is effective and well tolerated in patients with severe CC. It improves whole gut transit, reducing straining, softening stools and reducing time to first bowel movement.

Abstract
PURPOSE Human papilloma virus infections of the anogenital region are very common and cause condylomata acuminata; cervical, penile, vulvar, or perianal intraepithelial neoplasia; and more rarely, invasive cancer. The currently available therapies often result in painful, extensive, slow-healing ulcerations and frequent early relapses. This study was aimed at determining the efficacy of topical application of the antiviral agent cidofovir at 1 percent. METHODS Twenty patients treated with coagulations were compared with 27 patients treated with cidofovir. Lesions refractory to cidofovir were cleared up with additional coagulations. The number of patients previously treated for condylomata did not differ between the two groups. Significantly more patients treated with cidofovir, however, had an impaired immune status (37 percent) compared with the patients treated with coagulations (5 percent). RESULTS Cidofovir alone cured the lesions in 32 percent of the patients and induced partial regression in 60 percent. However, in smokers, complete resolution of the condylomata occurred only in 16.6 percent compared with 66 percent of nonsmokers (P = 0.03). The number of coagulation sessions was much lower (P < 0.0005) in the cidofovir treated group (1 +/- 0.8 vs. 2.9 +/- 2). Furthermore, the relapse rate was significantly lower in the cidofovir group (3.7 vs. 55). All recurrences in the electrocoagulation group occurred within four months of confirmed lesion clearance. Topical applications of cidofovir 1 percent were well tolerated. Thirty-three percent of the patients reported only mild pain caused by erosive dermatitis. In contrast, coagulations caused painful ulcerations that necessitated the use of analgesics in all patients treated this way. CONCLUSIONS Topical applications of cidofovir, an antiviral compound with activity against human papilloma virus, is effective in the majority of patients with perianal condylomata and is a valuable adjuvant to surgical treatment of these lesions.

Abstract
OBJECTIVES Although the clinical efficacy of infliximab as measured by closure of fistulas in Crohn's disease has been demonstrated, its influence on the inflammatory changes in the fistula tracks is less clear. The aim of the present study was to assess the behavior of perianal fistulas before and after infliximab treatment. METHODS Magnetic resonance imaging (MRI) and clinical evaluation were performed in a total of 18 patients before and after treatment with infliximab. An MRI-based score of perianal Crohn's disease severity was developed using both criteria of local extension of fistulas (complexity, supralavetoric extension, relation to the sphincters and of active inflammation (T2 hyperintensity, presence of cavities/abscesses, and rectal wall involvement). RESULTS The MRI score was reliable in assessing the fistula tracks, with a good interobserver concordance (p < 0.001). Fistula tracks with signs of active inflammation were found in all 18 patients at baseline and collections in seven. After short-term infliximab treatment, active tracks persisted in eight of 11 patients who had clinically responded to infliximab. After long-term (46 wk) infliximab therapy, MRI signs of active track inflammation had resolved in three of six patients. CONCLUSIONS We have developed an MRI-based score of perianal Crohn's disease severity to assess the anatomical evolution of Crohn's fistulas. Our study demonstrates that despite closure of draining external orifices after infliximab therapy, fistula tracks persist with varying degrees of residual inflammation, which may cause recurrent fistulas and pelvic abscesses. Whether complete fistula fibrosis occurs over time with repeated infliximab infusions needs further study.

Abstract
The epidemiology of irritable bowel syndrome (IBS) in Europe and North America was analyzed from published material. The percentage of the population of Western civilisation with IBS symptoms is between 10 and 15% in most studies. The proportion of a Western population visiting a doctor for IBS symptoms is around 5%. The prevalence of IBS and the proportion of consulters do not seem to depend on age in an adult population. The female-to-male ratio of IBS in the population is close to 2. It is higher in IBS consulters in primary care and may be as high as 3 or 4 in tertiary referral centers. At least in patients from these centers, the number of physician visits and colonoscopies is considerable. Most of the consulters get a drug prescription.

Abstract
OBJECTIVE To compare the healing rate after several types of surgical repair of rectovaginal fistula (RVF) in Crohn's disease, and to identify factors predicting a successful outcome. PATIENTS AND METHODS A Medline review of the literature since 1980 and analysis of our results in 32 consecutive patients was done. RESULTS All types of repair (rectal, vaginal, anocutaneous advancement flap, or perineoproctotomy with fistula closure) seem to be equally effective. Healing after a first repair is observed in 58 (46-71)%. Healing can still be obtained at subsequent attempts in 62 (40-71)% of the patients. The reported overall healing rate is 75 (56-93)%. The need for proctectomy after an attempt to repair was 6 (0-27)% in these series. Using a tailored surgical approach, we observed primary healing in 57%, healing after one or more supplementary procedures in 71%, for a total 'definitive' closure rate of 75%. Anal continence was never compromised and all temporary stomas (12 patients) could be closed. Univariate analysis identified number of Crohn's sites, presence of extra-intestinal disease and previous Crohn's proctitis to be related with problematic healing after a surgical repair. A positive relation was found between extra-intestinal disease and the number of repairs needed to ultimately obtain healing, whereas the relation with previous right hemicolectomy was negative. Multivariate analysis revealed the number of Crohn's sites as the only factor predicting problematic healing. A defunctioning stoma was not related to the healing rate and had its intrinsic morbidity with supplementary hospitalization (9.6 days). After a median follow-up of 40.4 (range 8-87) months, we observed 4 late recurrences in 25 patients with healed RVF (16%). CONCLUSION Closure of a RVF in Crohn's disease should not be considered an easy undertaking, especially in patients with several Crohn's sites. In this very heterogeneous group of patients the technique is adapted to the nature and the extent of accompanying anorectal disease. Construction of a temporary stoma is not mandatory and can be limited to complex cases. Healing can be obtained in 75% of all patients, although a late recurrence might occur.

Abstract
A large proportion of irritable bowel syndrome (IBS) patients also complain of other functional disorders, such as headache, noncardiac chest pain, low back pain, and dysuria. Some of these features, particularly headache, may have a negative influence on the outcome of IBS. In a large proportion of female IBS patients, sexual intercourse triggers the symptoms, and frequently IBS symptoms exacerbate during menses. These gynecological-type symptoms often mislead the patients to the gynecological clinic, which may imply unnecessary investigations and inappropriate treatments. The diagnostic criteria of the fibromyalgia syndrome include IBS, and hence, the apparent relationship of both syndromes is difficult to analyze. On the other hand, no convincing evidence has been produced to date to sustain an association between IBS and the chronic fatigue syndrome.

Abstract
Crohn's disease is rarely associated with Sweet's syndrome. We report a 32-year old woman who presented with diarrhea, fever and disseminated erythematous plaques on the arms and the trunk. After colonoscopy with biopsies, Crohn's disease was diagnosed. Skin biopsy showed a dense infiltration of neutrophilic polymorphonuclear leukocytes, establishing also the diagnosis of Sweet's syndrome. Crohn's disease is one of several systemic diseases that may underlie Sweet's syndrome. Treatment with methylprednisolone resulted in a rapid improvement of both gastro-intestinal symptoms and skin lesions.

Abstract
BACKGROUND Previous studies have failed to identify manometric patterns of gastrointestinal motor activity that can distinguish dyspepsia from health. AIMS To test the hypothesis that the combined use of prolonged, ambulatory, antrojejunal manometry and computer aided analysis in patients selected for the severity of their symptoms could reveal new insights into gastrointestinal motor activity in patients with severe motility-like dyspesia. METHODS Twenty four hour antrojejunal ambulatory manometry was performed in 14 patients and 10 healthy volunteers. Parameters characterising digestive and fasted motility were obtained by a validated computer program and visual analysis. Scoring systems quantified the degree of dysmotility as well as the severity of symptoms. Gastric emptying times were measured in each patient. RESULTS There was a high prevalence of antral and jejunal dysmotility both during the interdigestive period (71% of patients) and in the postprandial period (78%). During the interdigestive period there was a reduced incidence of antral and jejunal phases, a larger contribution of phase 2 during migrating motor complex cycles, and aberrant configuration of jejunal phase 3 in 29% of patients. Postprandially, the most frequent finding was antral (29% of patients) or jejunal (29%) hypomotility or hypermotility. Minute rhythm was present both during the postprandial (29% of patients) and the interdigestive period (21%). There was no positive correlation between symptom scores, gastric half emptying times, or motility scores. CONCLUSION Even with the use of prolonged recordings and advanced computer aided analysis, it is not possible to identify a specific motor pattern which can discriminate patients with severe motility-like dyspepsia from those with other diseases or even healthy individuals. Clinical symptoms or gastric half emptying times are poor predictors of gastrointestinal dysmotility in patients with functional dyspepsia.

Abstract
The aim of this study were to provide a detailed comparison of duodenal and jejunal motor activity in healthy individuals by utilizing prolonged ambulatory manometry in combination with computer-aided analysis. Intraluminal pressure profiles were studied in the duodenum and jejunum of 18 healthy volunteers over 24 hr. The subjects ingested two meals, both of 800 kcal and of equal chemical composition, at two different times of the day. Over the whole interdigestive period, phase III motor activity started more frequently distal than proximal to the ligament of Treitz. However, an increasing time of fasting was linearly related to an increasing number of phase IIIs originating proximal to the ligament of Treitz (r = 0.95). Both meals induced a postprandial motor pattern of similar duration and contractile activity. As compared to the jejunum, individual duodenal contractions during the postprandial period and during phase II had a higher duration and amplitude. Propagated clustered contractions occurred more frequently in the duodenum than in the jejunum, both in the interdigestive and digestive state. Jejunal clusters comprised a higher number of individual contractions of lower amplitude and duration. In healthy man duodenal and jejunal motor activity are different, both in the digestive and interdigestive state. The differences include the number of activity fronts traversing these segments of the gut, the number and organization of propagated clustered contractions, and subtle changes in the amplitude, duration, and coordinated propagation of individual contractions. These changes presumably reflect a regulatory capability of the small intestine to modulate the rate of transit of intraluminal content through different segments of the gut.

Abstract
An algorithm has been developed for the offline analysis of prolonged manometric recordings in the upper small intestine of humans. Sample data are acquired in the human duodenum and jejunum six solid-state strain-gauge transducers mounted on a silicon catheter that is connected to a portable digital recording device. The data are sampled at 4 Hz and filtered. For accurate calculations, the filtered signals are converted to cubic B-spline functions of order four. Based on an exponential weighted moving average, a base-line is calculated from the signal. Contractions are recognised on the basis of thresholds for minimum amplitude and duration. The developed algorithm calculates properties of these contractions, such as amplitude, duration, area and a motility index. In addition, the program automatically recognises normal motor patterns of the fasted human small intestine, such as the migrating motor complex, and aids in the identification of the postprandial motor pattern. Motor patterns are defined in terms of properties such as contraction frequency and propagation. In a validation procedure using conventional manual analysis, the program correctly identifies the number of individual contractions with a 98% confidence interval and also correctly recognises 96% of phase 3 motor activity.

Abstract
Cisapride is a substituted benzamide compound that stimulates motor activity in all segments of the gastrointestinal tract by enhancing the release of acetylcholine from the enteric nervous system. Cisapride is administered orally in the treatment of gastro-oesophageal reflux disease, functional dyspepsia, gastroparesis, chronic intestinal pseudo-obstruction syndromes and chronic constipation. In gastro-oesophageal reflux disease in both adults and children, cisapride provides symptomatic improvement and mucosal healing. Long term treatment with cisapride is effective in the prevention of relapse of oesophagitis. Cisapride improves gastric emptying rates and improves symptoms in patients with gastroparesis of various origins. Unlike domperidone and metoclopramide, long term administration of cisapride seems to result in persistently enhanced gastric emptying. Cisapride is also effective in improving symptoms in patients with functional dyspepsia. In comparative studies in patients with functional dyspepsia, cisapride was at least as effective as metoclopramide, domperidone, clebopride, ranitidine and cimetidine. Cisapride increases stool frequency and reduces laxative consumption in patients with idiopathic constipation. Severe cases of slow transit constipation seem refractory to cisapride. Clinical studies also indicate that cisapride might be effective in the treatment of chronic intestinal pseudo-obstruction, postoperative ileus, peptic ulcer and irritable bowel syndrome. Further clinical studies are warranted to define the role of cisapride in these conditions. The dosage of cisapride ranges from 5mg 3 times daily to 20mg twice daily. Cisapride is generally well tolerated, both during short and long term treatment. In children, cisapride is also well tolerated in doses of 0.2 to 0.3 mg/kg, 3 to 4 times daily.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
Preliminary reports have suggested that dilatation using hydrostatic through the scope balloons may be useful for the treatment of Crohn's strictures, A prospective longterm follow up (mean (SD) 33.6 (11.2) months) was carried out in 55 Crohn's patients with 59 ileocolonic strictures submitted to 78 dilatation procedures. Hydrostatic balloons were used (Rigiflator, Microvasive) with a diameter of 18 mm on inflation. As soon as the balloons became available dilatation up to a diameter of 20 and 25 mm was attempted. The dilatations were performed under general anaesthesia using propofol (Diprivan). The patients were kept for one night in the hospital after dilatation. Seventy (90%) procedures were technically successful and passage of the stricture with a 13.6 mm diameter colonoscope was possible after 73% of the dilatations. Complications occurred in six patients (11%; 8% of procedures), including sealed perforations (n = 2), retroperitoneal perforations (n = 2), and intraperitoneal perforations (n = 2). Two of the patients were treated surgically with a one stage resection of the stricture and recovered uneventfully. Four patients were treated conservatively with intravenous fluids and antibiotics. There was no mortality. Dilatation completely relieved obstructive symptoms in 20 patients after one procedure, in another 14 patients after two (n = 13) or three (n = 1) dilatations. Total longterm success rate was 34 of 55 patients (62%). Nineteen patients (38%) were operated on because of persistent obstructive symptoms. The data show that endoscopic dilatation using the through the scope hydrostatic balloon system relieves obstructive symptoms resulting from ileocolonic Crohn's strictures. The procedure, however, carries a definite risk of perforation.

Abstract
Gastro-intestinal stricture frequently is a complication in Crohn's disease and often recurs after surgical resection. Stenosis with acute inflammation can be treated by anti-inflammatory medication. A conservative approach of sclerotic strictures has been possible since the introduction of Gruentzig balloon catheters for dilating stenosis in different parts of the gastro-intestinal tract. We present a prospective follow-up study in 55 patients, on the long-term results and safety of hydrostatic balloon dilations of ileo-colonic Crohn's strictures.

Abstract
BACKGROUND 5-hydroxytryptamine-3 (5-HT3) receptor antagonists inhibit gastric phase-3 motor activity in the dog. This study examined the role of 5-HT3 receptors in the generation of gastric phase 3 of the migrating motor complex in humans. METHODS Interdigestive motor activity was recorded manometrically in 16 subjects before and after administration of ondansetron, a selective 5-HT3 receptor antagonist. Plasma motilin values were also assayed in 7 individuals. The incidence of gastric activity fronts before and after ondansetron was compared with a control group that had not received ondansetron. The ability of erythromycin to induce a gastric activity front in the presence of ondansetron was also evaluated in 7 subjects. RESULTS The incidence of gastric activity fronts was 69% before ondansetron vs. 19% after ondansetron. In contrast, in the control group there was no significant change in the incidence of gastric activity fronts over time. Activity fronts preceding ondansetron were associated with motilin peaks while activity fronts after ondansetron were not. Despite the previous administration of ondansetron, erythromycin induced gastric activity fronts in 89% of cases. CONCLUSIONS Selective antagonism of 5-HT3 receptors suppresses the gastric component of phase-3 motor activity and simultaneously suppresses plasma motilin peaks. The results suggest that the suppression of gastric activity fronts is achieved via the suppression of plasma motilin peaks because in the presence of ondansetron a motilin agonist like erythromycin restores the gastric phase 3.

Abstract
The long-term effects of endoscopic dilation of colonic or ileo-colonic Crohn's disease strictures were analyzed. In 18 patients with a Crohn's disease-related low gastrointestinal stricture, the stenosis was dilated using through-the-scope (TTS) balloon catheters. A dilation to a diameter of 18 mm was always attempted. Treatment was successfully carried out in 16 patients, and was followed by immediate symptomatic relief in 14 patients. Long-term success was observed in nine patients. There were no complications. Balloon catheter dilation of a colonic stricture or stricture of an ileo-colonic anastomosis was found to be safe and effective. This treatment modality can be an alternative to surgery in a selected group of patients.

Abstract
We studied 5 healthy volunteers and 9 patients with irritable bowel syndrome (IBS) during infusion of the colon with saline solution, bile acids, fatty acids and balloon distension. Our results show that the pain threshold was significantly (p less than 0.001) higher in controls than in IBS patients. Bile acids and fatty acids brought on the habitual pain in 5/7 and 7/8 patients respectively, while they did not have any effect in the control group. On the basis of our data we can conclude that the IBS patients are more sensitive to colonic distension and perfusions, thus suggesting a non-specific irritability of the colon which could be a characteristic of these patients.
