[Children with inflammatory bowel disease: Assessment of the transition from the pediatric to the adult care unit]. / Évaluation de la transition pédiatrie-gastroentérologie d'adultes des enfants atteints de maladie inflammatoire cryptogénique intestinale.

AIM: Assess the transition of children followed for inflammatory bowel disease (IBD) to the adult gastroenterology care unit and the development of joint medical visits (JMVs). PATIENTS AND METHOD: This study was conducted at the Rennes University Hospital (Brittany, France). All patients with IBD and relayed to an adult gastroenterologist (GE) between 2000 and 2014 were included. The following medical data were collected: age, gender, clinical status, disease activity, type of follow-up (freelance or at hospital), medical history, disease locations, and treatments received. Patients who were relayed in the same hospital attended a JMV with both the pediatric and adult gastroenterologists. Patients and parents were interviewed with a questionnaire sent by mail. They were asked how they had perceived the transition with questionnaires containing specific items about the JMV. The answers of the patients who attended JMVs were compared to those who did not attend. RESULTS: Eighty-two patients were included. The patient response rate was 56 % (parents, 59 %). The average age at transition was 18±0.8years. Fifty patients were relayed in the same hospital with 30 attending a JMV. These patients suffered from more severe disease than other patients. Thirty-nine patients felt ready to transition (87 %). The JMV was deemed beneficial or very beneficial (74 %) for both follow-up and the benefits of the GE's knowledge of the medical file. The parents' responses did not differ from the patients'. CONCLUSION: Development of the JMV enables a successful transition for pediatric patients with IBD. It could be improved by developing specific therapeutic education sessions based on transition training.

Prospective cohort study of phenotypic variation based on an anal sphincter function in adults with fecal incontinence.

BACKGROUND: One-third of patients with fecal incontinence (FI) do not have any anal dysfunction. The aim was to characterize patients with FI with normal anal function compared with patients with anal weakness. METHODS: The general characteristics and data of anal manometry, endosonography, and defecography of patients who were evaluated for FI at a single institution from 2005 to 2015 were prospectively assessed. Fecal incontinence was defined by the Cleveland Clinic Incontinence Score (CCIS) >4. Anal weakness was defined by one or more of the three following parameters: <25 mmHg at the upper part of the anal canal, <26 mmHg at the lower part of the anal canal, and <60 mmHg for the mean squeeze pressure. KEY RESULTS: A total of 439 patients with FI were included (152 with normal anal function/287 with anal weakness). Severe constipation (Kess score ≥21) was predominant in patients with normal anal function (44/151 vs 50/284, respectively; p = 0.0054). Fecal incontinence with normal anal function was significantly associated with lower age (>63 years; odds ratio [OR] = 0.29), higher weight (>65 kg; OR = 1.69), fecal urgency (OR = 1.58), less severe FI score (CCIS score >10; OR = 0.52), higher abdominal pressure (>36 mmHg; OR = 2.15), and paradoxical puborectal contraction (OR = 2.07) in a multivariate analysis model. CONCLUSION & INFERENCES: Fecal incontinence with normal anal function is a specific phenotype that involves distal constipation and may be an early stage of FI with anal weakness. Physicians should adapt their management to focus on the treatment of constipation.

Anorectal dysfunction in patients with ulcerative colitis: impaired adaptation or enhanced perception?

BACKGROUND: Rectal disorders during ulcerative colitis (UC) drastically alter the quality of life and may result from an impairment of rectal perception and compliance. This study aims to assess anorectal disorders in patients with mild-to-moderate UC. METHODS: Anal pressures and the rectal responses to phasic rectal isobaric distension in 10 patients with mild-to-moderate UC were prospectively compared with those in 10 healthy volunteers (HVs). KEY RESULTS: The patients in each group were similar regarding age, gender, and delivery. In the resting state, the anal canal pressures were similar between the groups. Only the squeeze pressures of the lower anal canal were significantly lower in UC patients than in HVs. During phasic isobaric distension, rectal sensitivity was similar between the groups, whatever the step of distension. Isobaric rectal distension resulted in a significant decrease of the rectoanal inhibitory reflex and a decrease in rectal tone and a significant drop in rectal compliance in UC patients compared with HVs. CONCLUSIONS & INFERENCES: Patients showing mild-to-moderate UC experience rectal compliance and innervation disorders without a significant change in rectal sensitivity. The findings of this work suggest impairment not only of the properties of the rectal wall but also of intrinsic innervation. Repeated evaluation over time may be helpful for analyzing the reversibility of the process after healing.

Anorectal stricture in 102 patients with Crohn's disease: natural history in the era of biologics.

BACKGROUND: The natural history of nonfistulising perianal Crohn's disease (PCD) remains unknown. AIM: To assess the long-term outcome of anorectal strictures. METHODS: All outcomes of PCD patients with anorectal stricture followed in a single unit from 2005 to 2013 were reviewed, as well as subsequent therapeutic management. Cumulative incidence of stricture healing (disappearance of the anal stricture) was estimated using a Kaplan-Meier method and factor associated with an unfavourable course (persistent stricture S2, persistent stoma or proctectomy) with nonparametric test. RESULTS: A total of 102 patients (M/F: 37/65) were included. The duration of CD at diagnosis was 8.9 years. After a median follow-up period of 2.8 years, 52 of the 88 followed patients (59%) achieved anorectal stricture healing. Two patients (2%) developed anal adenocarcinoma. Female gender [HR 2.05 (1.1-4.03), P = 0.0221], disease duration of CD of less than 10 years [HR 1.94 (1.01-3.63), P = 0.0271], and anal fistula at stricture diagnosis [HR 2.36 (1.21-5.05), P = 0.0106) were significantly associated with anorectal stricture healing in a multivariate analysis model. Twenty-eight patients (32%) had an unfavourable course at the end of follow-up. Gender and introduction or optimisation of TNFα antagonist treatment decreased the risk of unfavourable course in multivariate analysis. Conversely, the Luminal B2 phenotype at CD diagnosis was the only factor associated with unfavourable course. CONCLUSIONS: Anorectal stricture does not imply a nonreversible and complicated condition related to severe perianal Crohn's disease. However, both the diagnosis of cancer and sepsis drainage remain challenging in this situation.

Effects of transcutaneous tibial nerve stimulation on anorectal physiology in fecal incontinence: a double-blind placebo-controlled cross-over evaluation.

BACKGROUND: Transcutaneous electrical tibial nerve stimulation (TENS) is of growing interest for the treatment of fecal incontinence (FI), but its mechanism of action remains uninvestigated. We aimed to further assess the anorectal response to TENS in a dynamic model. METHODS: We performed a placebo-controlled, randomized, double-blinded crossover study in 19 patients suffering from FI to assess the effects of TENS on anorectal function. Anorectal physiology and perception were recorded through two sequences of rectal isobaric distension using an electronic barostat device to measure anal and rectal pressures, rectal volumes, and perception scores. KEY RESULTS: Maximal rectal pressure and volume variation were affected by TENS, with higher mean maximal rectal pressure (5.33 and 4.06 mmHg in the active and sham TENS respectively, p < 0.0001) and lower volume variation (11.45 and 14.7 mL in the active and sham stimulation respectively, p < 0.05). Rectal compliance was not modified by active TENS. Pressure of the upper anal canal was significantly lower with raised isobaric distension in sequences assigned to active TENS. CONCLUSIONS & INFERENCES: Acute TENS modified anorectal physiology by strengthening the myogenic response to distension rather than increasing muscle relaxation and related rectal compliance in patients with FI.

Prevalence and predictive factors of the need for surgery for advanced colorectal adenoma.

AIM: Endoscopic resection is the primary treatment for colorectal adenoma, but in some cases surgery is necessary. The aim of this retrospective study was to define the prevalence and predictive factors for surgery in patients with advanced colorectal adenoma managed in a referral endoscopy centre. METHOD: Consecutive patients diagnosed with advanced adenoma (Class 4 in the Vienna classification) during a colonoscopy from 2007 to 2009 in the endoscopy centre of the University Hospital of Rennes were included. Predictive factors of surgery were determined by univariate and multivariate analysis. RESULTS: Two-hundred and twelve (135 male) patients with a mean age of 65.8 years were included. The reason for colonoscopy was for diagnosis in 63.2%, surveillance in 25.5% and screening in 11.3%. These referred patients amounted to 20.8% of all patients having colonoscopy. Surgery was performed in 13.7% of the 212 patients and in 16 (8.3%) of the 192 patients in whom endoscopic removal was attempted. In the subgroup of 192 patients, univariate analysis revealed that body mass index (P = 0.04), histology (P = 0.002), size (P = 0.03) and macroscopic appearance (P < 0.001) of the polyp were associated with surgery. Multivariate analysis revealed that the macroscopic appearance and histology only were significantly associated with surgery. CONCLUSION: Surgery was needed in 13.7% of patients with an advanced adenoma, but in only 8.3% of the subgroup of 192 patients in whom endoscopic removal was attempted. Factors associated with surgery included macroscopic appearance and histology.

Incontinence in full-thickness rectal prolapse: low level of improvement after laparoscopic rectopexy.

AIM: The study aimed to quantify incontinence before and after laparoscopic rectopexy in patients suffering from rectal prolapse. METHOD: Eighty-five patients underwent laparoscopic rectopexy to treat rectal prolapse between 2003 and 2009. Symptomatic and functional data were collected prospectively before and after surgery by self-administered questionnaires including the Cleveland Clinic Fecal Incontinence Score (CCIS) and constipation, gastrointestinal quality of life and urinary incontinence questionnaires. Incontinence was considered to be present when the CCIS remained at ≥ 5 after surgery. RESULTS: After a mean follow-up period of 36 months after surgery, 83% of the patients reported good to excellent results. Continence was improved in 58 (68%), with a significant decrease in the continence score (-3.4 ± 5.8, P = 0.001). However, 50 (58.9%) patients remained incontinent: 47 (55%) reported urge incontinence and 27 (32%) had passive leakage. Incontinence for liquid stool, incontinence for solid stool and the need for protection was seen in 43 (51%), 35 (41%) and 43 (51%) patients. Manometry, defaecography and ultrasonography were not associated with any improvement. In contrast, the patients' average age (60.2 ± 15.8 vs 46.9 ± 15.5 years; P = 0.003), symptom duration before surgery (58.1 ± 70.1 vs 29.5 ± 33.3 months; P = 0.011), preoperative urinary incontinence score (10.7 ± 10.8 vs 4.2 ± 5.7; P = 0.0131) and faecal incontinence score (12.9 ± 4.9 vs 7.1 ± 6; P < 0.0001) were significantly higher in patients suffering from postoperative incontinence. CONCLUSION: Despite some continence improvement in two-thirds of patients who underwent surgery for rectal prolapse, the level of improvement remained low in more than half of the patients.

Comparison between a guaiac and three immunochemical faecal occult blood tests in screening for colorectal cancer.

BACKGROUND: The aim of this study was to compare the performance of the guaiac-based faecal occult blood test (G-FOBT), with that of three immunochemical faecal occult blood tests (I-FOBT) which allow automatic interpretation. PATIENTS AND METHODS: Under the French organised screening programme, 85,149 average-risk individuals aged 50-74 participating in the third screening round, performed both the G-FOBT (Hemoccult-II test) and one of the I-FOBTs: FOB-Gold, Magstream and OC-Sensor. RESULTS: Given the chosen threshold, the positivity ratio between the different I-FOBTs and the G-FOBT was 2.4 for FOB-Gold, 2.0 for Magstream and 2.2 for OC-Sensor (P=0.17). The three I-FOBTs were superior to the G-FOBT for colorectal cancer (CRC) detection. The ratios for detection rates were 1.6 (FOB-Gold), 1.7 (Magstream) and 2.1 (OC-Sensor) (P=0.74). For non-invasive CRC they were, respectively, 2.5, 3.0 and 4.0 (P=0.83) and for advanced adenomas 3.6, 3.1 and 4.0 (P=0.39). CONCLUSIONS: This study provides further evidence that I-FOBT is superior to G-FOBT. None of the three I-FOBTs studied appeared to be significantly better than the others.

Underlying functional bowel disorder may explain patient dissatisfaction after haemorrhoidal surgery.

AIM: The aim of this study was to assess patient dissatisfaction and functional symptoms following haemorrhoid surgery, aspects of which are seldom covered in other published series. METHOD: A self-administered questionnaire was mailed to 359 consecutive patients (prospective database; 198 men, 161 women; median follow up, 59 [1-120] months) who underwent either Milligan-Morgan haemorrhoidectomy (n=205) or stapled haemorrhoidopexy (n=154). RESULTS: The response rate was 72%; 2.4% of patients had no opinion, 13.6% were dissatisfied, 33.0% were satisfied, and 51.0% were very satisfied with the treatment. Dissatisfied patients were more likely to be women and more likely to have a long history of constipation and irritable bowel syndrome. The duration of surgery and the rates of pre- and postoperative complications did not differ between groups. Residual bleeding (49% vs 32%), prolapse (67% vs 31%) and pain (91% vs 55%) occurred more frequently in the dissatisfied group compared with the satisfied group (P<0.001). Incontinence (4 [0-16] vs 1 [0-15]; P=0.0003) and constipation (19 [1-34] vs 8 [0-31]; P<0.0001) scores were significantly higher in the dissatisfied group compared with satisfied patients. Anal pain was the predominant symptom associated with dissatisfaction in a logistic regression model. CONCLUSION: Persistent pain remains the major long-term factor associated with dissatisfaction after surgery for haemorrhoids.

Infliximab for refractory ulcerative proctitis.

BACKGROUND: Efficacy of infliximab in treating ulcerative proctitis remains unknown. AIM: To evaluate the clinical, biological and endoscopic efficacy of infliximab therapy in refractory proctitis. METHODS: The charts of 420 patients treated with infliximab for ulcerative colitis were reviewed. Thirteen patients were treated with infliximab for refractory ulcerative proctitis in six referral centres between 2005 and 2009. RESULTS: Following infliximab therapy induction, 9/13 patients (69%) had a complete response (defined as absence of diarrhoea and blood), 2/13 (15%) had a partial response and 2/13 (15%) were primary nonresponders. The median follow-up was 17 months (range, 3-48). Among the 11 patients with clinical response after infliximab induction therapy, 9 (82%) patients maintained response at last follow-up. Disappearance of rectal disorders was observed in all nine patients who maintained clinical response at last follow-up. Following infliximab induction therapy, the mean CRP level fell from 12.8 mg/L to 4.7 mg/L. Endoscopic evaluation was performed before and after infliximab in seven patients, showing an improvement in mucosal lesions in four patients, persistent mild endoscopic activity in two patients and no improvement in one patient. One patient underwent proctocolectomy. CONCLUSION: Infliximab therapy seems to be effective in inducing and maintaining a clinical response in refractory ulcerative proctitis.

[Diagnosis of dyschezia]. / Stratégie diagnostique d'une dyschésie.

Outlet constipation is a frustrating condition for both patients and clinicians. The former are reluctant to evoke this disabling condition. For the latter, decision-making remains uncertain since non-specific strategies are unhelpful (constipation). Thus, careful symptomatic assessment (stool consistencies), dynamic examination of the anorectal area (anismus, rectocele) and balloon expulsion test may plan therapeutic options in current situations.

Long-term outcome of non-fistulizing (ulcers, stricture) perianal Crohn's disease in patients treated with infliximab.

BACKGROUND: In Crohn's disease, anal ulcers and stricture can be disabling. AIM: To evaluate long-term outcome of non-fistulizing perianal Crohn's disease under infliximab. METHODS: The medical records of 99 patients with non-fistulizing perianal Crohn's disease at first infliximab infusion were reviewed. Complete responses (ulcer healing or stricture regression) after induction infliximab therapy and at the maximal follow-up were assessed. RESULTS: Ninety-four patients (94.9%) had ulcers, 22 (22.2%) had stricture and 31 (31.3%) had draining perianal fistulas at first infliximab infusion. After infliximab induction therapy, 40/94 (42.5%) patients with ulcers, 4/22 (18.2%) with stricture and 10/31 (32.2%) with fistulas had a complete response. Eight patients were lost to follow-up. After a median follow-up of 175 weeks (range, 13-459), complete response rates for ulcers, stricture and fistulas were 72.3% (68/94), 54.5% (12/22) and 54.8% (20/31) respectively. Long-term response for cavitating ulcer was positively associated with concomitant immunosuppressant use (P = 0.017) and older age (P = 0.049). Among the 12 patients with complete regression of stricture, 6 patients also had anal dilatation. Complete response was associated with perianal pain relief and disappearance of soiling. Three patients with ulcers developed an anal abscess. CONCLUSIONS: Infliximab therapy may be effective in inducing and maintaining response for ulcers.

Management of gastroesophageal reflux disease by primary care physicians and gastroenterologists: a prospective study of patients' records.

BACKGROUND: We previously compared the perceptions and practices of primary care physicians (PCP) and gastroenterologists (GE) in the management of gastroesophageal reflux disease (GORD), but the data were only declarative statements. OBJECTIVE: The aim of the present study was to analyze the respective management of GORD by PCP and GE on the basis of patients' records, and to look for any discrepancies between the declared and actual practices in both groups of physicians in the management of GORD. METHODS: A representative sample of French physicians was asked to enroll two consecutive patients with frequent and typical symptoms of GORD into a prospective observational survey. RESULTS: A total of 136 PCP and 91 GE participated in the survey and enrolled 271 and 182 patients, respectively, with frequent GORD symptoms (453 patients in total). Patients consulting GE were slightly younger, and had waited longer before arranging a consultation despite having symptom severity and impact on daily life similar to those visiting PCP. Most patients enrolled by GE had undergone upper GI endoscopy (95% versus 64% from PCP, P<0.01). In both groups of physicians, recourse to endoscopy for their patients was more frequent than they estimated. Prescription therapies for GORD were usually Proton Pump Inhibitors (PPI) in both groups of physicians and were in keeping with the declared findings. CONCLUSIONS: Despite differences between patients' characteristics, the management of frequent GORD was similar by both groups of physicians. The reasons why both groups of physicians underrated their actual recourse to endoscopy for their patients warrant further investigation.

Transition of patients with inflammatory bowel disease from pediatric to adult care.

AIM: This study was designed to ascertain the perception of patients (and their parents) followed-up for inflammatory bowel disease (IBD) concerning the transition from pediatric to adult care. PATIENTS AND METHODS: Forty-eight youths with IBD who had transited from pediatric to adult care were surveyed. Their age at transition was 17.9+/-0.9 years. Thirty-four patients (71%) had been referred to a gastroenterologist working in the same hospital and, in 27 cases, after having attended a joint pediatric-adult care visit. RESULTS: The response rate was 71%. Twenty-nine patients (85%) and 25 parents (74%) felt they were ready to transit into adult care. Seven patients (22%) and 10 parents (32%) were apprehensive about transition to adult gastroenterology. All patients considered the joint medical visit beneficial in terms of transmitting information from their medical records and 93% considered it beneficial for building confidence in the new gastroenterologist. All parents considered the joint medical visit helpful for building the children's confidence in their new doctor. At the time of the survey, 29 patients (85%) were continuing to be followed-up by the same gastroenterologist. CONCLUSION: Effective planning, including a joint medical visit, enabled successful, well-coordinated transition to adult medical-care follow-up.

[Pseudomalignant endoscopic appearance in hyperplastic polyp at esophagogastric junction: case report]. / Aspect endoscopique pseudocarcinomateux d'un polype hyperplasique au niveau de la jonction oesogastrique: à propos d'un cas.

Hyperplastic polyps are by far the most common benign tumors in the stomach larger than 5mm. Although the malignant potential of hyperplastic gastric polyps was originally denied, a low risk for carcinomatous conversion is now recognized. Its has been recommended that all gastric polyps of 5mm or more in diameter have to be removed. We present here the case of a large hyperplastic gastric polyp located at the esophagogastric junction with endoscopic malignant appearance. The description of its endoscopic and histological characteristics gives us the opportunity to discuss the difficulty of endoscopic diagnosis in the case of gastric polyps and to remind their prognosis.

Gastric involvement in juvenile polyposis associated with germline SMAD4 mutations: an entity characterized by a mixed hypertrophic and polypoid gastropathy.

Exclusively gastric form of juvenile polyposis associated with germline SMAD4 mutation is a rare clinical entity and is usually difficult to diagnose in the absence of colorectal lesions. We describe the phenotype of two unrelated cases of exclusive or predominant gastric expression of juvenile polyposis. Endoscopically, we found an unusual hypertrophic and polypoid gastropathy with abundant mucus adhering to the mucosal surface. Initially diagnosed as hyperplastic polyps, examination of gastric macrobiopsy specimens and identification of SMAD4 gene mutation in both cases confirmed the diagnosis. Close upper GI surveillance was proposed in case 1 and prophylactic total gastrectomy in the second one. Juvenile polyposis limited to the stomach is a rare condition that is linked to SMAD4 mutations. Such a diagnosis should be considered whenever a mixed, hypertrophic and polypoid gastropathy is encountered.

Colonoscopy results of a French regional FOBT-based colorectal cancer screening program with high compliance.

BACKGROUND AND STUDY AIMS: Mass screening for colorectal cancer in France was initiated in pilot regions on the basis of the fecal occult blood test (FOBT) followed by colonoscopy in positive cases. We report the colonoscopy results in one of the first areas to be screened (Ille et Vilaine). PATIENTS AND METHODS: Of the total regional population of 908,449, 187,342 of the 213,635 potential screening candidates who were aged 50 - 74 years were invited for FOBT. Of the 51.3% compliant individuals, 2.6% were positive, and of these 90.7% agreed to undergo colonoscopy (n = 2246). The colonoscopy procedure details, findings, and complications were recorded. Subjects were classified according to the most advanced lesion. Positive predictive values of FOBT were calculated according to sex and age. RESULTS: Colonoscopy was complete in 96.3% of cases. Only 23 adverse events were encountered (1.02%). Colorectal cancer was diagnosed in 237 cases (10.6%, 78.4% of which were clinical stages I - II). The rates of overall adenomas and advanced adenomas were 33.1 % and 21.6 %, respectively. The risk of cancer and advanced adenoma increased significantly in men and in older people. CONCLUSION: The results of mass screening with FOBT followed by colonoscopy in this population-based study are very encouraging in terms of compliance, early findings, and complications. Extension of this program to the whole of France is justified.
