Subjective expectations regarding longevity and future health: a cross-sectional survey among patients with Crohn's disease. Colorectal Dis 2021; 23:105-113. [PMID: 32920967 DOI: 10.1111/codi.15357] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/06/2020] [Revised: 08/28/2020] [Accepted: 08/31/2020] [Indexed: 02/08/2023]
Abstract
AIM The aim was to explore the subjective health expectations (sHE) of patients with Crohn's disease (CD) for both the near future and the elderly. METHOD A cross-sectional survey was performed in four gastroenterology centres in Hungary. Consecutive outpatients with CD with age ≥ 18 were recruited. Socio-demographic and disease characteristics were recorded and the Crohn's Disease Activity Index (CDAI), Perianal Disease Activity Index, Patients' Global Assessment (PGA) and current pain visual analogue scale (VAS) were assessed. Subjective life expectancy (sLE) was explored and compared to statistical life expectancy. Current health and sHE for 1 year ahead and for ages 60/70/80/90 were assessed using the descriptive system of the EQ-5D-3L. RESULTS In all, 206 patients (54.9% men) with a mean age of 34.7 (SD 10.5 years) and disease duration of 10.5 (SD 6.3) years were studied. The CDAI score was 110.5 (SD 77.0) and 66% were treated by biologic drugs. Mean current EQ-5D-3L score was 0.80 (SD 0.17) and patients expected a 0.05 (SD 0.15) improvement within a year (P < 0.05). For ages 60/70/80/90, a mean EQ-5D-3L score of 0.59, 0.38, 0.10 and -0.12 respectively was provisioned. Age, current health status, sLE, PGA and pain VAS showed significant correlation with both 1-year and older age sHE (P < 0.05). Long-term sHE and sLE were negatively affected by the presence of extraintestinal manifestations but not by previous CD-related surgery. CONCLUSION Patients with CD expect severe deterioration in health in later life. Given that unrealistic sHE may affect patients' current quality of life and health behaviour, we encourage physicians to explore and consider CD patients' sHE in clinical care.

Patient and general population values for luminal and perianal fistulising Crohn's disease health states. THE EUROPEAN JOURNAL OF HEALTH ECONOMICS : HEPAC : HEALTH ECONOMICS IN PREVENTION AND CARE 2019; 20:91-100. [PMID: 31102158 PMCID: PMC6544586 DOI: 10.1007/s10198-019-01065-y] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 03/05/2019] [Accepted: 04/13/2019] [Indexed: 05/04/2023]
Abstract
BACKGROUND In patients with Crohn's disease (CD), luminal disease activity paralleled by perianal fistulas may seriously impair health-related quality of life (HRQoL). Health utility values are not available from patients with CD that reflect the health loss associated with both luminal and perianal CD. OBJECTIVE To generate utilities for luminal and concomitant perianal fistulising CD health states directly from patients and from members of the general public. METHODS A cross-sectional survey was undertaken enrolling CD patients and a convenience sample of members of the general population. Respondents were asked to evaluate four common CD heath states [severe luminal disease (sCD), mild luminal disease (mCD), severe luminal disease with active perianal fistulas (sPFCD), and mild luminal disease with active perianal fistulas (mPFCD)] by 10-year time trade-off (TTO). In addition, patients assessed their current HRQoL by the TTO method. RESULTS Responses of 206 patients (40.8% with perianal fistulas) and 221 members of the general population were analysed. Mean ± SD utilities among patients for sPFCD, sCD, mPFCD and mCD states were 0.69 ± 0.33, 0.73 ± 0.31, 0.80 ± 0.29 and 0.87 ± 0.26. Corresponding values in the general public were: 0.59 ± 0.31, 0.65 ± 0.29, 0.80 ± 0.26 and 0.88 ± 0.25. Patients with active perianal fistulas, previous non-resection surgeries, and higher pain intensity scores valued their current health as worse (p < 0.05). CONCLUSIONS TTO is a feasible method to assess HRQoL in patients with perianal fistulising disease, often not captured by health status questionnaires. Utilities from this study are intended to support the optimization of treatment-related decision making in patients with luminal disease paralleled by active perianal fistulas.

Abstract
PURPOSE The EuroQol five-dimension questionnaire (EQ-5D) is the most commonly used instrument to obtain utility values for cost-effectiveness analyses of treatments for Crohn's disease (CD). We aimed to compare the measurement properties of the two adult versions of EQ-5D (EQ-5D-3L and EQ-5D-5L) in patients with CD. METHODS Between 2016 and 2017, a multicentre cross-sectional survey was carried out. Consecutive outpatients with CD completed the 3L, 5L and EQ visual analogue scale (VAS). Disease severity was graded by the Crohn's Disease Activity Index (CDAI) and Perianal Disease Activity Index (PDAI). The 3L and 5L were compared in terms of feasibility, agreement, ceiling effect, redistribution properties, discriminatory power, convergent and known-groups validity. RESULTS Two-hundred and six patients (54.9% male, mean age 35 ± 11 years) participated in the survey. For 3L, 25 unique health states were observed versus 59 for the 5L. The overall ceiling effect decreased from 29.6% (3L) to 25.5% (5L). Absolute discriminatory power improved (mean Shannon index 0.84 vs. 1.18). The 3L correlated stronger with EQ VAS and CDAI scores, whereas the 5L with PDAI. The 5L demonstrated a better known-groups validity on the basis of age, perianal fistulas, extraintestinal manifestations and disability. CONCLUSIONS This is the first study to report the impact of CD on quality of life using the EQ-5D-5L questionnaire. The 5L seems to perform better than 3L in terms of feasibility, ceiling effect, discriminatory power and known-groups validity. Understanding the differences in psychometrics between the 3L and 5L is essential as they have substantial implications for financial decision-making about CD treatments.

Randomised clinical trial: mesalazine versus placebo in the prevention of diverticulitis recurrence. Aliment Pharmacol Ther 2017; 46:282-291. [PMID: 28543263 PMCID: PMC5518301 DOI: 10.1111/apt.14152] [Citation(s) in RCA: 30] [Impact Index Per Article: 4.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/20/2017] [Revised: 02/27/2017] [Accepted: 04/27/2017] [Indexed: 01/15/2023]
Abstract
BACKGROUND Previous studies have reached conflicting conclusions regarding the efficacy of mesalazine in the prevention of recurrent diverticulitis. AIM To investigate the efficacy and safety of mesalazine granules in the prevention of recurrence of diverticulitis after acute uncomplicated diverticulitis. METHODS Two phase 3, randomised, placebo-controlled, double-blind multicentre trials (SAG-37 and SAG-51) investigated mesalazine granules in patients with prior episodes (<6 months) of uncomplicated left-sided diverticulitis. Patients were randomised to receive either 3 g mesalazine once daily or placebo (SAG-37, n=345) or to receive either 1.5 g mesalazine once daily, 3 g once daily or placebo for 96 weeks (SAG-51, n=330). The primary endpoint was the proportion of recurrence-free patients during 48 weeks (SAG-37 and SAG-51) or 96 weeks (SAG-51) of treatment. RESULTS Mesalazine did not increase the proportion of recurrence-free patients over 48 or 96 weeks compared to placebo. In SAG-37, the proportion of recurrence-free patients during 48 weeks was 67.9% with mesalazine and 74.4% with placebo (P=.226). In SAG-51, the proportion of recurrence-free patients over 48 weeks was 46.0% with 1.5 g mesalazine, 52.0% with 3 g mesalazine and 58.0% with placebo (P=.860 for 3 g mesalazine vs placebo) and over 96 weeks 6.9%, 9.8% and 23.1% respectively (P=.980 for 3 g mesalazine vs placebo). Patients with only one diverticulitis episode in the year prior to study entry had a lower recurrence risk compared to >1 episode. Safety data revealed no new adverse events. CONCLUSION Mesalazine was not superior to placebo in preventing recurrence of diverticulitis.

Abstract
BACKGROUND AND AIMS Biosimilar infliximab CT-P13 is approved for all indications of the originator product in Europe. Prospective data on its efficacy, safety, and immunogenicity in inflammatory bowel diseases are lacking. METHODS A prospective, nationwide, multicentre, observational cohort was designed to examine the efficacy, safety, and immunogenicity of CT-P13 infliximab biosimilar in the induction treatment of Crohn's disease [CD] and ulcerative colitis [UC]. Demographic data were collected and a harmonised monitoring strategy was applied. Early clinical remission, response, and early biochemical response were evaluated at Week 14, steroid-free clinical remission was evaluated at Week 30. Therapeutic drug level was monitored using a conventional enzyme-linked immunosorbent assay. RESULTS In all, 210 consecutive inflammatory bowel disease [126 CD and 84 UC] patients were included in the present cohort. At Week 14, 81.4% of CD and 77.6% of UC patients showed clinical response and 53.6% of CD and 58.6% of UC patients were in clinical remission. Clinical remission rates at Week 14 were significantly higher in CD and UC patients who were infliximab naïve, compared with those with previous exposure to the originator compound [p < 0.05]. Until Week 30, adverse events were experienced in 17.1% of all patients. Infusion reactions and infectious adverse events occurred in 6.6% and 5.7% of all patients, respectively. CONCLUSIONS This prospective multicentre cohort shows that CT-P13 is safe and effective in the induction of clinical remission and response in both CD and UC. Patients with previous infliximab exposure exhibited decreased response rates and were more likely to develop allergic reactions.

Abstract
INTRODUCTION C. difficile causes 25 percent of the antibiotic associated infectious nosocomial diarrhoeas. C. difficile infection is a high-priority problem of public health in each country. The available literature of C. difficile infection's epidemiology and disease burden is limited. AIM Review of the epidemiology, including seasonality and the risk of recurrences, of the disease burden and of the therapy of C. difficile infection. METHOD Review of the international and Hungarian literature in MEDLINE database using PubMed up to and including 20th of March, 2012. RESULTS The incidence of nosocomial C. difficile associated diarrhoea is 4.1/10 000 patient day. The seasonality of C. difficile infection is unproved. 20 percent of the patients have recurrence after metronidazole or vancomycin treatment, and each recurrence increases the chance of a further one. The cost of C. difficile infection is between 130 and 500 thousand HUF (430 € and 1665 €) in Hungary. CONCLUSIONS The importance of C. difficile infection in public health and the associated disease burden are significant. The available data in Hungary are limited, further studies in epidemiology and health economics are required.

Abstract
INTRODUCTION Clostridium difficile is the leading cause of antibiotic associated infectious nosocomial diarrhoea. Limited number of new pharmaceutical products have been developed and registered in the past decades for the treatment of Clostridium difficile infection. The available scientific evidence is limited and hardly comparable. AIM To analyse the clinical efficacy and safety of metronidazole, vancomycin and fidaxomicin in the therapy of Clostridium difficile infection. METHODS Systematic review and meta-analysis of the literature data. RESULTS Meta-analysis of literature data showed no significant difference between these antibiotics in clinical cure endpoint (odss ratios: fidaxomicin vs. vancomycin 1.19; vancomycin vs. metronidazol 1.69 and fidaxomicin vs. metronidazol 2.00). However, fidaxomicin therapy was significantly more effective than vancomicin and metronidazol in endpoints of recurrence and global cure (odds ratios: fidaxomicin vs. vancomycin 0.47; vancomycin vs. metronidazol 0.91 és fidaxomicin vs. metronidazol 0.43). There was no significant difference between fidaxomicin, vancomycin and metronidazole in safety endpoints. CONCLUSIONS Each antibiotic similarly improved clinical cure. Fidaxomicin was the most effective therapeutic alternative in lowering the rate of recurrent Clostridium difficile infections.

Abstract
UNLABELLED The quality of endoscopic examinations substantially determines their value. In developed countries, Continuous Quality Management is used to improve it permanently. In Hungary there is no example for measuring quality in the field of gastrointestinal endoscopy. AIM The measurement and improvement of quality of endoscopy applying completeness index (cecum intubation rate) during colonoscopy. PATIENTS AND METHODS The authors defined base values retrospectively from 841 colonoscopy reports, performed in the last quarter of the year, before starting the project. The next two years (3160 colonoscopy in 2009 and 3167 in 2010) every three months they calculated the cecum intubation rate for each endoscopist. RESULTS The cecum intubation rate was 81.6% in the base period. When the authors excluded examinations with poor preparations and those with a previously unknown stenosis that prevented the total colonoscopy, the adjusted cecal intubation rate was 90.9%. In the next 2 years, the cecum intubation rate was 84.2% and 85.7% (p = 0.0394), while adjusted cecum intubation rate proved to be 92.3% and 92.6% (p = 0.381 NS) for the whole endoscopy unit. Of the 14 endoscopists only 6 reached an adjusted cecum intubation rate of 90%, but in the second year of the project 10 of them reached this rate and only one endoscopist remained below 87%. The endoscopists performing more than 100 colonoscopies per year had better adjusted cecum intubation rate (base 91.2%; 92.7% and 93.1% during the 2 project years) compared to those with less than 100 colonoscopies per year (base, 86.7%; project period, 85.5 and 89%). CONCLUSIONS The evaluation and publicity of the cecal intubation rate resulted in an improvement of the quality of colonoscopy. The authors also presented that endoscopists performing more than 100 colonoscopies per year have better endoscopic quality.

Abstract
BACKGROUND Adalimumab is a fully human monoclonal antibody targeting tumour necrosis factor with proven efficacy in the treatment of Crohn's disease (CD). AIM To investigate the predictors of medium-term clinical efficacy and mucosal healing during adalimumab therapy, in patients with CD, in specialised centres approved for biological therapy in Hungary. METHODS Data capture of the 201 CD patients was standardised and prospective (male/female: 112/89, median age: 33.0 years, duration: 8 years). Previous infliximab therapy had been administered in 48% of patients, concomitant steroids in 41%, azathioprine in 69% and combined therapy in 27% of patients. RESULTS Overall clinical response and remission rates at 24 weeks were 78% and 52%, respectively; at 52 weeks were 69% and 44%, respectively. Endoscopic improvement and healing were achieved in 43% and 24% of patients. In a logistic regression model, clinical efficacy and CRP at week 12, need for combined immunosuppression at induction, shorter disease duration and smoking were identified as independent predictors for 12-month clinical outcome, whereas CRP at week 12, clinical remission at week 24, inflammatory parameters and nonsmoking were associated to endoscopic improvement/healing. Intensification to weekly dosing was needed in 16% of patients. Parallel azathioprine therapy and clinical remission at week 12 were inversely associated with dose escalation. CONCLUSIONS Clinical efficacy and normalised CRP at week 12 (early deep clinical remission) are associated with medium-term clinical efficacy and mucosal healing during adalimumab therapy, whereas need for combined immunosuppression at induction and smoking status are predictors for non-response. Parallel azathioprine therapy may decrease the probability for dose escalation.

METHODS Data of 201 Crohn's disease patients were prospectively captured (male/female: 112/89, median age: 24 years, duration: 8 years). Previous infliximab therapy was given in 97 (48.3%) patients, concomitant steroids in 41.3% and azathioprine in 69.2% (combined: 26.4%) of patients. RESULTS Overall clinical response and remission rates at 24 and 52 weeks were 78% and 52%, and 69.4% and 44.4%, respectively. Endoscopic improvement and healing was achieved in 43.1% and 23.6%, respectively. In a logistic regression model, clinical efficacy and normalized C-reactive protein at week 12, need for combined immunosuppression at induction, shorter disease duration and smoking were identified as independent predictors for 12-month clinical outcome, while normalized C-reactive protein at week 12, clinical remission at week 24, frequency of previous relapses and smoking were associated to endoscopic improvement/healing. Dose intensification to weekly dosing was needed in 16.4%. Parallel azathioprine therapy and clinical remission at week 12 was inversely associated to dose escalation to weekly dosing. CONCLUSION Clinical efficacy and normalized C-reactive protein at week 12, need for combined immunosuppression, luminal disease and smoking are predictors for medium term clinical efficacy/mucosal healing during adalimumab therapy, while parallel azathioprine therapy may decrease the probability for dose escalation.

Abstract
UNLABELLED Previous studies have suggested an increasing use of complementary and alternative medicine (CAM) in patients with inflammatory bowel disease (IBD). Furthermore, a significant number of IBD patients fail to comply with treatment. The aim of our study was to evaluate the prevalence of non-adherence the use of CAM in Hungarian patients with IBD. METHODS A total of 655 consecutive IBD patients (Crohn's disease [CD]: 344, age: 38.2 + or - 12.9 years; ulcerative colitis [UC]: 311, age: 44.9 + or - 15.3 years) were interviewed during the visit at specialists by self-administered questionnaire including demographic and disease-related data, as well as items analyzing the extent of non-adherence and CAM use. Patients taking more then 80% of each prescribed medicine were classified as adherent. RESULTS The overall rate of self reported non-adherence (CD: 20.9%, UC: 20.6%) and CAM (CD: 31.7%, UC: 30.9%) use was not different between CD and UC. The most common causes of non-adherence were: forgetfulness (47.8%), too many/unnecessary pills (39.7%), being afraid of side effects (27.9%) and too frequent dosing. Most common forms of CAM were herbal tee (47.3%), homeopathy (14.6%), special diet (12.2%), and acupuncture (5.8%). In CD, disease duration, date of last follow-up visit, educational level and previous surgeries were predicting factors for non-adherence. Alternative medicine use was associated in both diseases with younger age, higher educational level and immunosuppressant use. In addition, CAM use in UC was more common in females and in patients with supportive psychiatric/psychological therapy. CONCLUSIONS Non-adherence and CAM use is common in patients with IBD. Special attention should be paid to explore the identified predictive factors during follow-up visits to improve adherence to therapy and improving patient-doctor relationship.

Abstract
UNLABELLED In addition to lower esophageal sphincter (LES) relaxations and decreased LES tone, increased intra-abdominal pressure can also play role in the pathogenesis of gastroesophageal reflux disease (GERD),. AIM To analyze the correlation between occupation-related increased intra-abdominal pressure or straining (experienced for years) and the prevalence of GERD symptoms. METHODS Reflux symptoms were analyzed through a questionnaire among professional singers, wind players and glassblowers in comparison with controls. RESULTS Heartburn, regurgitation and hoarseness were significantly more frequent among professional singers than in controls (P<0.001). Among wind players heartburn (P<0.05) and regurgitation (P<0.01), among glassblowers regurgitation (P<0.01) were significantly more frequent in comparison with control subjects. Reflux symptoms correlated significantly with the duration of professional activity (P<0.05). CONCLUSIONS Results suggest that reflux symptoms are more frequent among subjects with occupation-related increased intra-abdominal pressure. GERD seems to be a work-related disease in this aspect.

Abstract
Background Infliximab (IFX) has proven to be an effective addition to the therapeutic arsenal for refractory, fistulizing, and steroid dependent Crohn's disease (CD), with efficacy in the induction and maintenance of clinical remission of CD. Our objective in this study is to report the nationwide, multicenter experience with IFX induction therapy for CD in Hungary. Methods During a 6-year-period, beginning in 2000, a total of 363 CD patients were treated with IFX as induction therapy (5 mg/kg IFX infusions given at week 0, 2 and 6) at eleven centers in Hungary in this observational study. Data analysis included patient demographics, important disease parameters and the outcome of IFX induction therapy. Results Three hundred and sixty three patients (183 women and 180 men) were treated with IFX since 2000. Mean age was 33.5 ± 11.2 years and the mean duration of disease was 6.7 ± 6.1 years. The population included 114 patients (31.4%) with therapy-refractory CD, 195 patients (53.7%) with fistulas, 16 patients (4.4%) with both therapy-refractory CD and fistulas, and 26 patients (7.2%) with steroid dependent CD. Overall response rate was 86.2% (313/363). A higher response rate was observed in patients with shorter disease duration (p = 0.05, OR:0.54, 95%CI:0.29-0.99) and concomitant immunosuppressant therapy (p = 0.05, OR: 2.03, 95%CI:0.165-0.596). Concomitant steroid treatment did not enhance the efficacy of IFX induction therapy. Adverse events included 34 allergic reactions (9.4%), 17 delayed type hypersensitivity (4.7%), 16 infections (4.4%), and 3 malignancies (0.8%). Conclusion IFX was safe and effective treatment in this cohort of Hungarian CD patients. Based on our experience co-administration of immunosuppressant therapy is suggested in patients receiving IFX induction therapy. However, concomitant steroid treatment did not enhanced the efficacy of IFX induction therapy.

Abstract
Aetiology of inflammatory bowel disease (IBD) is complex and probably multifactorial. Nutrition has been proposed to be an important aetiological factor for development of IBD. Several components of the diet (such as sugar, fat, fibre, fruit and vegetable, protein, fast food, preservatives etc.) were examined as possible causative agents for IBD. According to some researchers infant feeding (breast feeding) may also contribute to the development of IBD. Though the importance of environmental factors is evidenced by the increasing incidence in developed countries and in migrant population in recent decades, the aetiology of IBD remained unclear. There are many theories, but as yet no dietary approaches have been proved to reduce the risk of developing IBD. The role of nutrition in the management of IBD is better understood. The prevention and correction of malnutrition, the provision of macro- and micronutrients and vitamins and the promotion of optimal growth and development of children are key points of nutritional therapy. In active disease, the effective support of energy and nutrients is a very important part of the therapy. Natural and artificial nutrition or the combination of two can be chosen for supporting therapy of IBD. The author summarises the aetiological and therapeutic role of nutrition in IBD.

Abstract
BACKGROUND An occupation-related susceptibility of professional singers to experience gastroesophageal reflux has been suggested. AIMS To investigate the prevalence of gastroesophageal reflux symptoms in a series of professional opera choristers, wind players, glassblowers and water polo players in comparison with a sample of general population. SUBJECTS AND METHODS A total of 202 professional opera choristers from well-known choirs in different Hungarian regions, 71 professional wind players, 43 glassblowers, 54 water polo players were identified and 115 control subjects were compared prospectively. Reflux symptoms together with selected individual characteristics and lifestyle habits were investigated in study groups through a reflux questionnaire. RESULTS Professional opera choristers reported a statistically significantly higher prevalence of heartburn, regurgitation and hoarseness than control subjects (p < 0.001). Among professional wind players, heartburn and regurgitation were significantly more frequent compared with controls (p < 0.05 and p < 0.01, respectively). Glassblowers reported a significantly higher prevalence of acid regurgitation in comparison with controls (p < 0.01). The prevalence of reflux symptoms in water polo players was similar to that of controls. In opera choristers, wind players and glassblowers, reflux symptoms appeared to be significantly correlated with the cumulative lifetime duration of professional singing, playing and working activity, respectively (p < 0.05). CONCLUSIONS Our results demonstrate that professional opera choristers, professional wind players and glassblowers have a higher prevalence of reflux symptoms compared with control subjects. Gastroesophageal reflux in these professions should be considered as a work-related disorder that may have an impact on quality of life and may negatively interfere with professional performance.

Abstract
BACKGROUND Malignant oesophageal stenosis can be caused by cancer of the oesophagus, gastric cardia, lungs, mediastinum or, rarely, breast. Most of these cases are inoperable due to advanced stage of the disease, comorbidities or age of the patients; and palliative treatment can be applied only. The quality of life is mostly determined by the extent of dysphagia. Several methods are available to palliate dysphagia. Hereby, the authors review their results with palliation of malignant oesophageal obstruction applying self-expanding metal stents. PATIENTS AND METHODS 68 endoscopic stent implantations were performed in 64 patients (15 female and 49 male) with malignant dysphagia between 2003 and 2008. After radiological investigations, distally deployed covered stents with or without an antireflux valve were placed, depending on the localization of the tumour. In one patient with a stenosis localized in the upper third of the oesophagus a proximally deployed covered stent was used. The aim was to re-establish oral nutrition and cover possible fistulas. RESULTS Significant improvement of swallowing was detected in every patient. Average dysphagia score has improved from 3.2 to 1.7. Technical difficulties during stenting occurred in a relatively low percentage of patients only (2 in 68; i.e. 2.94%). Fistulas were covered in every case. Early stent migration (<7 days) happened in one case. One patient suffered non-fatal myocardial infarction two days after stent placement. In 5 cases tumour in- and overgrowth, in 4 cases bleeding was seen as late complications. Oesophago-tracheal fistula was noted in three patients after stent implantation. Late stent migration (>7 days) occurred in two patients. Re-stenting was necessary in four cases, while three patients needed an upper GI endoscopy for cleansing the stent caused by food obstruction. CONCLUSIONS According to our data self-expanding metal stents are highly effective and safe for improving dysphagia. Stent-related complications are relatively rare. This method is highly recommended for palliation of malignant dysphagia.

Abstract
We have tested the role and significance of histology combined with cytology in the diagnosis of esophageal squamous cell carcinomas. Biopsy specimens and samples for cytological smear were taken by a fiberoptic flexible endoscope. In order to minimise the loss of biological sample, the residue from the brush was removed with rinsing fluid. From 1973 to 2005 we examined 820 patients with squamous cell carcinoma of the esophagus. Endoscopic biopsy yielded positive result in 97.2%. Cytology performed in 724 patients turned out to be positive in 90.3%. Both examinations were conducted in 648 patients (79%), and yielded positive result in 572 patients (88.3%). Negative biopsy result was obtained in 22 patients, however, 14 of them had positive cytological diagnosis. Both biopsy and cytology were negative in 8 cancer patients (1%). No complication was observed with either diagnostic technique. In our material cancer was diagnosed in 776 patients by histology. However, in a further 14 of 22 patients with negative histology, cancer was detected by cytology. This means that the presence of cancer was also confirmed on the basis of morphological features in 790 cases, i.e. in 96.3% of the patients. Our results show that the combined use of biopsy and cytology in malignant tumours yields high diagnostic accuracy. Since abrasion exfoliate cytology is a quick and useful diagnostic measure it should be a routine examination in the evaluation of abnormal changes in the esophageal mucosa. The examination of the rinsing fluid of the sampling brush, introduced by us, yielded additional diagnostic information.

Abstract
Among a total of 143 patients examined for diagnosis of adenocarcinoma of the cardia, intramural esophageal metastases were verified in six patients (4.19 %). In each case the diagnosis was confirmed by histological examination. The histological structure of the primary tumors and metastases was the same. Metastases were detected by endoscopic ultrasound examination in three cases. All the cardia tumors proved to be well advanced. As well as endoscopic identification of the primary tumor, thorough examination of the proximal part of the esophagus is of great importance.

Abstract
Nowadays the terminology used for the definition of adenocarcinomas at the oesophagogastric junction is "cardiac carcinoma", which can be easily misunderstood. This definition of adenocarcinomas of the oesophagogastric junction does not allow correct comparison of diagnosis (endoscopic, radiological and pathologic), epidemiology and surgical therapy in national and international aspects, because different tumours can develope in the same area, and all called cardia tumors. Siewert and Stein recommended a classification to solve this problem. The classification of the tumours is morphological/topographical. Type I is adenocarcinoma of the distal part of the oesophagus. Type II is adenocarcinoma of the real cardia and type III is subcardial gastric adenocarcinoma. At classification, we always consider results of endoscopy (ortograde and retroflexed view of the oesophago-gastric junction), the x-rays of the oesophagus and stomach, findings at the operation and pathohistologic results. Between 1/1/1974 and 31/12/2000, a total number of 50,878 upper panendoscopic examinations were performed at the Endoscopic Laboratory of the Surgical Department. Adenocarcinoma of the cardia was diagnosed in 488 patients. According to the Siewert-Stein classification, type I tumour was found in 123 (25.2%), type II in 240 (49.18%), and type III was present in 125 (25.61%) patients. The importance of this classification is it enables unified pre-operative assessment and it can also help to decide the type of the surgical intervention. In our patients with type I cancer--depending of the size of the tumour--distal 2/3 oesophagectomy with the resection of the proximal lesser curve of the stomach or total gastrectomy were performed. In the first group oesophago-jejuno-gastrostomy, in case of total gastrectomy Roux-en-Y loop anastomosis was created. In patients with types II and III cancers total gastrectomy was performed. In every patient lymphadenectomy was performed. We suggest the use of this new classification in clinical, gastroenterology--with special regard to the endoscopy--and pathology.

Abstract
In recent years push enteroscopy has become the most important method in the examination of patients with obscure gastrointestinal bleeding. We summarise our experiences with 148 enteroscopies performed on 140 patients with bleeding of unknown origin. The source of bleeding could be identified in 81 patients (57.86%). The most common lesions were small bowel tumors (13.57%) and vascular malformations (12.86%). Several patients (22.86%) referred for enteroscopy had lesions in the esophagus, stomach and proximal duodenum that were missed at upper endoscopy. The authors conclude that push enteroscopy has a major role in the evaluation of patients with obscure gastrointestinal bleeding. Enteroscopy should be the first diagnostic step after negative esophago-gastroduodenoscopy and negative colonoscopy. Enteroscopy seems to be superior to other diagnostic methods. It is well tolerable and is not time consuming.

Abstract
The authors report a combined occurrence of thrombophilia and colitis ulcerosa and provide an analysis of relevant references in earlier works. It is likely intertwinning of the two disease's symptoms, the chronic cause of the condition and the underlying molecular biology variations cannot be traced back to a single cause. Further research is required to establish whether the protein-C anomaly exhibited in the presented case is general in this condition or an individual occurrence. The publication emphasises that in future cases it will be advisable to perform tests capable of proving or refuting the abnormality of protein-C.

Abstract
Important progress has been made in recent years in the understanding of pathogenesis of Crohn's disease and ulcerative colitis, but the cause of IBD remains obscure, so curative therapy is still lacking. Current treatment strategies as sulphasalazine, mesalasine, glucocorticosteroids are mainly anti-inflammatory. In the past years the greatest advances have been characterised by the more widespread use of topically acting steroids, immunosuppressants and by the introduction of immunomodulatory agents as cytokines and anticytokines. The author summarises the standard therapy and new possibilities of medical treatment for IBD and suggests some algorythms for clinical practice.

Abstract
The PGE2, PGF2 alpha, PGI2, and TXB2 content in biopsies of healthy esophageal mucosa and inflamed mucosa and from subjects with chronic esophagitis was measured and statistically analyzed. No significant differences were found between the tissue concentrations of prostaglandins in the inflamed and the healthy mucosa, except for elevated PGI2 content in the inflamed esophageal mucosa in comparison to healthy mucosa. The prostaglandin content of jejunal mucosa was unchanged in jejunitis and in atrophy compared to findings in healthy subjects. Regression analysis revealed a significant negative correlation between the PGF2 alpha and PGI2 content in both inflamed esophageal and inflamed jejunal mucosa. In healthy mucosa, no correlation was found between the tissue concentrations of these two prostaglandins, either in the esophagus or in the jejunum. These results suggest the redistribution of cyclic endoperoxide metabolism under certain pathological conditions.

Abstract
The authors performed intraoperative colonoscopy in 31 patients. This examination is done if preoperative colonoscopy was not performed or incomplete, and intraoperative difficulty occurs. In addition, it is indicated to localize non-palpable lesions, to perform polypectomy (if unsuccessful preoperatively but manageable intraoperatively), to define the site of endoscopic polypectomy, in certain instances to determine the resection plane, and after resection of constrictive tumours to look over the proximal intestinal section, to detect the synchronous lesions. It is emphasized that by their method the opening of the lumen becomes avoidable thus resulting in a decreased postoperative morbidity and mortality.

Abstract
The author summarises the possibilities of small bowel endoscopy. In case of haemorrhage of unknown origin, enteroscopy may be helpful. Sonde type fiber- or video-enteroscopes can be used. This procedure is time-consuming and needs an experienced team. In case of life-threatening bleeding intraoperative enteroscopy is recommended. "Push" enteroscopy is the best, rapid method in the diagnostics of suspected diffuse intestinal diseases or circumscript lesions of the proximal small bowel. Adult or pediatric colonoscopies or jejunoscopes are available for this investigation. Endoscopic biopsy specimens are suitable for histological examination and for enzyme assay as well. Aspiration of jejunal fluid for bacteriological culture is a way for revealing of bacterial overgrowth. The author emphasises the importance of the deep duodenoscopy made by an upper panendoscope in the diagnostics of villous atrophy.

Abstract
Lithotomy and endoscopic sphincterotomy were carried out in a 83-year-old woman because of choledocholithiasis. One year later calculi and tomato skins were found in the common bile duct. Significance is attributed to the tomato skins in the development of calculi. The attention is drawn to the observation that operative interventions performed through the Vater's papilla, spontaneous or iatrogenic choledochoduodenal fistulas create favourable conditions for foreign material to get into the choledochus and this may cause lithogenesis.

Abstract
Jejunal lactase and sucrase activities were demonstrated on endoscopically obtained biopsy specimens by a rapid test which had been developed earlier. The results were compared with enzyme activities found by Dahlquist's method. The data suggest that the rapid test is suitable for the semiquantitative determination of lactase and sucrase, and the results correlate with enzyme activities measured by the Dahlquist assay. The main advantage of the test is that it is rapid, simple, and cheap, and because no special equipment is necessary, it can be used in any endoscopic department.

Abstract
The endogenous mucosal PG levels (PGE2, PGF2 alpha, PGI2, TXB2) of the gastric stump were investigated from biopsy materials, after partial gastrectomy made for ulcer disease. The mucosa of the stomach remnant were found to contain mainly PGE2 and PGI2. The PG contents of the mucosa of gastric stump were not influenced by the type of resection. Mucosal PG concentrations on the greater curvature were not dependent on the patients' age, the indication of the gastrectomy, the duration of postoperative interval, or the sex of the patient. There was no relation between the secretion capacity of the resected stomach and the mucosal PG contents of the greater curvature. After Billroth I and II gastrectomy procedures equivalently fair correlations have been established between the mucosal levels of PGE2 and PGF2 alpha, PGE2 and TXB2, PGF2 alpha and TXB2, PGI2 and TXB2 on the greater curvature, respectively. After both types of gastrectomy the mean PGI2 mucosal concentration of the greater curvature was significantly lower than those of the gastroenteroanastomosis and lesser curvature below the cardia, which in turn did not differ from each other. Biliary reflux does not cause characteristic alterations of the mucosal PG levels on the greater curvature. No definite relation between the histological findings of the mucosa and the PG concentrations was observed, which suggests a secondary role of the endogenous PGs in the pathogenesis of light microscopic mucosal alterations of the resected stomach.

Abstract
A new method for testing lactose intolerance was developed. The examination is performed by jejunoscopy using lactose dilution for provocation and sucrose for control. Macroscopic and microscopic changes in the jejunal mucosa are examined after administration of solutions. The results of this study demonstrated that lactose administration causes prompt change in the jejunal mucosa in cases of lactose intolerance but had no effect in cases of lactose tolerance. Administration of sucrose did not result in any change. This method is effective in proving lactose intolerance and may be useful to elucidate the pathogenesis of this disorder.
