Natural History of Perianal Fistulising Lesions in Patients With Elderly-onset Crohn's Disease: A Population-based Study

INTRODUCTION

Most studies of elderly-onset Crohn's disease [CD; diagnosed in patients aged 60 or over] have described a mild course. However, data on the natural history of perianal fistulising CD [pfCD] in this population are scarce. In a population-based cohort study, we described the prevalence, natural history, and treatment of pfCD in patients with elderly-onset CD vs patients with paediatric-onset CD.

METHOD

All patients diagnosed with CD at or after the age of 60 between 1988 and 2006, were included [n = 372]. Logistic regression, Cox models, and a nested case-control method were used to identify factors associated with pfCD.

RESULTS

A total of 34 elderly patients [9% of the 372] had pfCD at diagnosis. After a median follow-up of 6 years (interquartile range [IQR]: 3; 10), 59 patients [16%] had pfCD; the same prevalence [16%] was observed in paediatric-onset patients. At last follow-up, anal incontinence was more frequent in elderly patients with pfCD than in elderly patients without pfCD [22% vs 4%, respectively; p < 10-4]. Rectal CD at diagnosis was associated with pfCD: hazard ratio (95% confidence interval [CI] = 2.8 [1.6-5.0]). Although 37% of the patients received immunosuppressants and 17% received anti-tumour necrosis factor agents, 24% [14 out of 59] had a definitive stoma at last follow-up.

CONCLUSION

During the first 6 years of disease, the prevalence of pfCD was similar in elderly and paediatric patients. Rectal involvement was associated with the appearance of pfCD in elderly-onset patients. Around a quarter of patients with elderly-onset CD will have a stoma. Our results suggest that treatment with biologics should be evaluated in these patients.

Dramatic Increase in Incidence of Ulcerative Colitis and Crohn's Disease (1988-2011): A Population-Based Study of French Adolescents

OBJECTIVES

Few data are available to describe the changes in incidence of pediatric-onset inflammatory bowel disease (IBD). The aim of this study was to describe changes in incidence and phenotypic presentation of pediatric-onset IBD in northern France during a 24-year period.

METHODS

Pediatric-onset IBD (<17 years) was issued from a population-based IBD study in France between 1988 and 2011. Age groups and digestive location were defined according to the Paris classification.

RESULTS

1,350 incident cases were recorded (8.3% of all IBD) including 990 Crohn's disease (CD), 326 ulcerative colitis (UC) and 34 IBD unclassified (IBDU). Median age at diagnosis was similar in CD (14.4 years (Q1=11.8-Q3=16.0)) and UC (14.0 years (11.0-16.0)) and did not change over time. There were significantly more males with CD (females/males=0.82) than UC (females/males=1.25) (P=0.0042). Median time between onset of symptoms and IBD diagnosis was consistently 3 months (1-6). Mean incidence was 4.4/10⁵ for IBD overall (3.2 for CD, 1.1 for UC and 0.1 for IBDU). From 1988-1990 to 2009-2011, a dramatic increase in incidences of both CD and UC were observed in adolescents (10-16 years): for CD from 4.2 to 9.5/10⁵ (+126%; P<0.001) and for UC, from 1.6 to 4.1/10⁵ (+156%; P<0.001). No modification in age or location at diagnosis was observed in either CD or UC.

CONCLUSIONS

In this population-based study, CD and UC incidences increased dramatically in adolescents across a 24-year span, suggesting that one or more strong environmental factors may predispose this population to IBD.

Extra-intestinal Manifestations at Diagnosis in Paediatric- and Elderly-onset Ulcerative Colitis are Associated With a More Severe Disease Outcome: A Population-based Study

BACKGROUND AND AIMS

Data on extra-intestinal manifestations [EIM] and their impact on the disease course of ulcerative colitis [UC] in population-based cohorts are scarce, particularly in paediatric- and elderly-onset UC patients. The aims of this population-based study were to assess: 1] the occurrence of EIM in paediatric- and elderly-onset UC; 2] the factors associated with EIM; and 3] their impact on long-term disease outcome.

METHODS

Paediatric-onset [< 17 years at diagnosis] and elderly-onset UC patients [> 60 years at diagnosis] from a French prospective population-based registry [EPIMAD] were included. Data on EIM and other clinical factors at diagnosis and at maximal follow-up were collected.

RESULTS

In all, 158 paediatric- and 470 elderly-onset patients were included [median age at diagnosis 14.5 and 68.8 years, median follow-up 11.2 and 6.2 years, respectively]. EIM occurred in 8.9% of childhood- and 3% of elderly-onset patients at diagnosis and in 16.7% and 2.2% of individuals during follow-up [p < 0.01], respectively. The most frequent EIM was joint involvement [15.8% of paediatric onset and 2.6% of elderly-onset]. Presence of EIM at diagnosis was associated with more severe disease course [need for immunosuppressants or biologic therapy or colectomy] in both paediatric- and elderly-onset UC (hazard ratio [HR] = 2.0, 95% confidence interval [CI]: 1.0-4.2; and HR = 2.8, 0.9-7.9, respectively). Extensive colitis was another independent risk factor in both age groups.

CONCLUSIONS

Elderly-onset UC patients had lower risk of EIM either at diagnosis or during follow-up than paediatric-onset individuals. EIM at diagnosis predicted more severe disease outcome, including need for immunosuppressive or biologic therapy or surgery, in both paediatric- and elderly-onset UC.

Fully versus partially covered self-expandable metal stents in benign esophageal strictures

Self-expandable plastic stents are currently recommended for refractory benign esophageal strictures but they show disappointing results in terms of migration and long-term efficacy. We report here our experience in the management of benign esophageal strictures with partially covered (PCSEMS) and fully covered self-expandable metal stents (FCSEMS). We performed a retrospective analysis of self-expandable metal stent (SEMS) placements for benign esophageal strictures from 1998 to 2011 in Rouen University Hospital. Twenty-two patients (15 men, 7 women) attempted 40 esophageal SEMS placements (17 PCSEMS, 23 FCSEMS) during this period. All technical complications were migrations. Migration was noted after 3/17 PCSEMS (17.6%) and 4/23 FCSEMS placement (17.4%, P = ns). Clinical complications occurred after 6/17 PCSEMS and 2/23 FCSEMS placements (35.3% vs. 8.7%, P = 0.053). PCSEMS caused two major complications (fistulae) whereas FCSEMS did not cause any major complication (11.7% vs. 0%). Mean dysphagia score was significantly lower after SEMS placement (1.68 vs. 3.08, P < 0.001) with similar results for PCSEMS and FCSEMS. Stent placement resulted in long-term clinical success for 23.5% of PCSEMS and 34.7% of FCSEMS (P = 0.0505). FCSEMS provide satisfying clinical success rate with an acceptable complication rate and they could constitute a relevant therapeutic option in the management of benign esophageal strictures.

Yield and impact of emergency capsule enteroscopy in severe obscure-overt gastrointestinal bleeding

BACKGROUND AND STUDY AIMS

Patients with obscure-overt gastrointestinal bleeding (OOGIB) are defined by overt hemorrhage and negative upper and lower endoscopy findings. At present, the place of emergency capsule enteroscopy in patients with severe OOGIB is unknown. The aim of this study was to assess the diagnostic yield and the impact of emergency capsule enteroscopy on further management in patients with severe OOGIB.

PATIENTS AND METHODS

Between 2003 and 2010, we retrospectively included all patients with severe OOGIB who underwent emergency capsule enteroscopy in the 24-48 h following negative urgent upper and lower endoscopy. Severe OOGIB was defined by ongoing bleeding with hemodynamic instability and/or the need for significant red blood cell transfusion.

RESULTS

Out of 5744 patients hospitalized in our Gastrointestinal Bleeding Unit, 55 (1%) presented with severe OOGIB and underwent emergency capsule enteroscopy. Capsule enteroscopy showed blood in 41 patients (75%) and lesions in 37 patients (67%). Findings included small bowel angiodysplasia in 19 patients (35%), ulcers in 7 (13%), tumors in 5 (9%), small-bowel varices in 2 (3%), cecum angiodysplasia in 4 (7%), fresh blood in small bowel without identified lesion in 12 (22%). Specific diagnostic and therapeutic procedures were undertaken in 78 % of patients. Further management included endoscopy (54%), surgery (22%), and radiology (2%).

CONCLUSIONS

Emergency capsule enteroscopy identified bleeding lesions in 67 % of patients with severe OOGIB. Emergency capsule enteroscopy seems to be a promising diagnostic tool with a subsequent impact on clinical management in patients with severe OOGIB.

Lugol chromo-endoscopy versus narrow band imaging for endoscopic screening of esophageal squamous-cell carcinoma in patients with a history of cured esophageal cancer: a feasibility study

To date, Lugol chromo-endoscopy is the reference technique to detect an esophageal neoplasia in patients with prior esophageal squamous-cell carcinoma (ESCC), but is not easy to perform without general anesthesia, which can limit its use in routine practice. The objective of this study were to compare the accuracy of white light, narrow band imaging (NBI), and Lugol to detect esophageal neoplasia in patients with a history of cured ESCC, in a prospective study. Thirty patients were prospectively included between June 2006 and June 2009. They all had a history of cured ESCC. Esophageal mucosa was examined first using white light, second NBI, and third after Lugol staining. Histology was obtained in all abnormalities detected by white light, NBI, and/or Lugol. Five neoplastic lesions in five different patients were identified at histology, four cancers, and one high-grade dysplasia. NBI and Lugol both detected all esophageal neoplastic lesions, whereas white light detected the four cancers but missed the high-grade dysplasia. In this feasibility study, NBI and Lugol both detected all identified esophageal neoplasia in very high-risk patients of ESCC. This result suggests that NBI could be used instead of Lugol to detect an esophageal neoplasia in patients with high risk of ESCC, but needs to be confirmed in a larger study.

Endoscopic band ligation could decrease recurrent bleeding in Mallory-Weiss syndrome as compared to haemostasis by hemoclips plus epinephrine

BACKGROUND

Mallory-Weiss syndrome (MWS) with active bleeding at endoscopy may require endoscopic haemostasis the modalities of which are not well-defined.

AIM

To compare the efficacy of endoscopic band ligation vs. hemoclip plus epinephrine (adrenaline) in bleeding MWS.

METHODS

From 2001 to 2008, 218 consecutive patients with a MWS at endoscopy were hospitalized in our Gastrointestinal Bleeding Unit. In 56 patients (26%), an endoscopic haemostasis was required because of active bleeding. Band ligation was performed in 29 patients (Banding group), while hemoclip application plus epinephrine injection was performed in 27 patients (H&E group). Treatment efficacy and early recurrent bleeding were retrospectively compared between the two groups.

RESULTS

Primary endoscopic haemostasis was achieved in all patients. Recurrent bleeding occurred in 0% in Banding group vs. 18% in H&E group (P = 0.02). The use of hemoclips plus epinephrine (OR = 3; 95% CI = 1.15-15.8) and active bleeding at endoscopy (OR = 1.9; 95% CI = 1.04-5.2) were independent predictive factors of early recurrent bleeding.

CONCLUSIONS

Haemostasis by hemoclips plus epinephrine was an independent predictive factor of rebleeding. This result suggests that band ligation could be the first choice endoscopic treatment for bleeding MWS, but requires further prospective assessment.

Translocation of an intra-uterine contraceptive device with sigmoid penetration through an endometriosic nodule

The intra-uterine device (IUD) is the most common existing reversible contraception. Uterine perforation occurs in 0.6 to 3.4 per 1000 insertions. We describe the first report of IUD translocation and subsequent penetration of the sigmoid through an endometriosic nodule. A 44-year-old gravida 2 para 2 woman consulted for rectal bleeding and melena. Rectosigmoidoscopy revealed ischemic colitis secondary to the use of NSAIDs, which explained the bleeding, but also sigmoid perforation from part of an intra-uterine device. This was discovered by chance. Perforation had occurred though an endometriosic nodule.

Safety and outcome of definitive chemoradiotherapy in elderly patients with oesophageal cancer

Little is known about chemoradiotherapy (CRT) in elderly patients with a locally advanced oesophageal cancer (OC). The aim of our study was to evaluate the tolerance and the outcome of elderly patients older than 70 years treated with CRT for a non-metastatic OC. Chemoradiotherapy was based on radiotherapy combined with a cisplatin-based chemotherapy. Clinical complete response (CCR) to CRT was evaluated on upper digestive endoscopy and computed tomography scan 6-8 weeks after CRT completion. One hundred and nine consecutive patients were included. A CCR was observed in 63 patients (57.8%) and 2-year survival was 35.5%. Adverse events > or =grade 3 were observed in 26 (23.8%) patients. Chemotherapy dose reduction, chemotherapy delays more than 1 week, and treatment discontinuation were observed in 33 (30.3%), 45 (41.3%), and 17 patients (15.6%), respectively. Comorbidity index according to Charlson score was significantly associated with treatment tolerance. In multivariate analysis, a CCR to CRT (P<0.01), a dose of radiotherapy > or =80% (P=0.02), and a Charlson score < or =2 (P=0.046) were identified as independent prognostic factors of overall survival. These results suggest that CRT could be considered as an effective treatment without major toxicity in elderly patients with OC.
