RESUMO
INTRODUCTION: The incidence of acute pancreatitis has been increasing over the past twenty years and there is still no causal treatment available. Although cases of severe acute pancreatitis account for only about a fifth of all cases of acute pancreatitis, high morbidity and lethality call for an optimization and unification of treatment procedures. METHODS: We operated on 27 patients suffering from severe acute pancreatitis in the past five years. We compared selected parameters such as gender, age, body mass index, aetiology, presence of type 2 diabetes, BISAP score, previous minimally invasive treatment and presence of the intraabdominal compartment syndrome. RESULTS: The average age of men and women was similar in our group. Most patients were overweight or obese. Alcoholic aetiology was more common in men while biliary aetiology prevailed in women. The mortality rate was 26% in our group. The intra-abdominal compartment syndrome followed by emergency decompression surgery was present in one fourth of the patients. A minimally invasive approach was used in approximately in one half of the patients, and surgical treatment was used only in cases where the minimally invasive approach failed. CONCLUSION: After each surgical revision, clinical deterioration of the patient´s condition occurs during the first two to three days in response to operative stress. Therefore, the current trend in the treatment of acute pancreatitis is to proceed as conservatively as possible, or using the minimally invasive approach, and surgical treatment should be reserved only for conditions that cannot be managed otherwise. If surgical treatment is used, it is advisable to perform cholecystectomy, whatever the aetiology of the pancreatitis.

Electrogastrography (EGG) is a non-invasive method for the assessment of gastric myoelectrical activity. Porcine EGG is comparable with human one. The purpose of this study was to evaluate the effect of atropine and neostigmine on the EGG in experimental pigs. Adult female pigs were administrated atropine (1.5 mg i.m., n=6) and neostigmine (0.5 mg i.m., n=6) after the baseline EGG, followed by a 90-min trial recording (MMS, Enschede, the Netherlands). Running spectral analysis was used for the evaluation. The results were expressed as dominant frequency of slow waves and EGG power (areas of amplitudes). Neostigmine increased continuously the dominant frequency and decreased significantly the EGG power. Atropine did not change the dominant frequency significantly. However, atropine increased significantly the EGG power (areas of amplitudes) from basal values to the maximum at the 10-20-min interval. After that period, the areas of amplitudes decreased significantly to the lowest values at the 60-90-min interval. In conclusion, cholinergic and anticholinergic agents affect differently EGG in experimental pigs.

Autonomic neuropathy of the gastrointestinal tract is a common complication of diabetes mellitus. However, it is seldom recognised properly as it is rarely considered. In some patients, it might be asymptomatic or hardly compensatable diabetes can be the only one sign. There are non-invasive diagnostic methods to assess gastric emptying rate (13C-octanoic acid breath test) or myoelectric activity of the stomach (electrogastrography). The principle treatment comprises optimal control of diabetes and use of prokinetics.

Biodegradable stents, which are made of various synthetic polymers, such as polylactide or polyglycolide, or co-polymers, such as polydioxanone, can be used for the treatment of benign refractory stenoses of the gastrointestinal tract. Here we report 11 patients (median age 41) with stenosing Crohn's disease of the small and/or large intestine. Endoscopic insertion of a biodegradable stent was successful at the first attempt in all patients except one. Subsequent follow-up was for a mean of 16 months, median 17 months, range 12-29 months. Early stent migration (between 2 days and 8 weeks) was seen in three patients. Mucosal overgrowth (epithelial hyperplasia) was not observed in any of the patients during the follow-up period. The high rate of early stent migration might be solved by appropriate tailoring and further improvements in the design of the biodegradable stents. Proof of long-term efficacy and safety requires further studies.

BACKGROUND: Nonsteroidal anti-inflammatory drugs may cause severe injury to all parts of the gastrointestinal tract. It has been hypothesised that probiotic bacteria might reduce this adverse effect. The aim of this study was to perform a morphometric evaluation of the gastrointestinal tract in experimental pigs treated using a 10-day high-dose of indomethacin with or without Escherichia coli Nissle 1917 (EcN). METHODS: Twenty-four healthy mature pigs were included: Group A (controls; 6 animals), Group B (EcN; n = 6), Group C (indomethacin; n = 6) and Group D (EcN & indomethacin; n = 6). EcN (3.5 × 10(10) live bacteria/day for 14 days) and/or indomethacin (15 mg/kg/day for 10 days) were administered. Specimens of the stomach, small and large bowel were routinely processed for microscopic examination. The height of glandular mucosa, height and width of interfoveolar spaces and villi and basement size of epithelial cells were evaluated. RESULTS: Different effects of indomethacin and EcN on particular parts of the gastrointestinal tract were shown. The indomethacin and probiotics group demonstrated a significantly lower height of cryptal mucosa and colonocytes and widening of the basement size of colonocytes compared to controls (p = 0.004; p < 0.001; p = 0.025). The height of cryptal mucosa was significantly higher in the EcN group compared to controls (p = 0.001). CONCLUSIONS: Indomethacin alone induced marked adaptation of the gastric mucosa. EcN alone provided a significant favourable trophic effect on the colonic mucosa. However, indomethacin and probiotics administered together comprise the worst impact on all porcine stomach, small and large bowel.

Helicobacter pylori (Hp) is the most common chronic bacterial infection in humans worldwide. The prevalence of Hp infection is high in developing countries (80-90%) and lower in developed countries (10-30%). In vast majority of infected individuals, the infection is acquired early in life. The risk of Hp infection is related to low socio-economic status and living conditions at early childhood (density of housing, overcrowding, number of siblings, sharing a bed, and lack of running water, low education of parents). Smoking is a risk factor of Hp infection in adults. In developed countries including the Czech Republic, the overall prevalence of Hp infection has fallen dramatically over recent decades. This decrease can be explained mostly by the relatively favourable and improving socio-economic conditions. However, it is necessary to consider also the fundamental determinants of "modern times" that could cause gradual disappearing of Hp from the human "microbiome".

The authors present a case of papillary adenoma of the extrahepatic biliary tract presenting as obstructive jaundice. The diagnosis was based on the endoscopic retrograde cholangiopancreatography (ERCP), and above all cholangioscopy findings. The patient was treated by bile duct resection with Roux-en-Y hepaticojejunostomy. Adenoma of the bile duct is a rare entity. Only a few cases have been described in the world literature so far.

THE AIM: The aim of this thesis was to elucidate more differences between a familial and sporadic inflammatory bowel disease by comparing certain clinical data. METHODS: We assessed 248 patients with inflammatory bowel disease (IBD) observed in 1994-2004 in the Academic Department of Gastroenterology at the Medical Faculty in Hradec Králové. To get information about the defined characters we obtained from the questionary and the hospital data. RESULTS: We did not identify any relationship between the onset of the disease and a certain age group, yet males seem to be more prone to familial Crohn's disease. The more frequent familial form of Crohn's disease was the fibro-stenotic one. There were no differences in the onset of the disease. We did not prove the differences in extraintestinal signs, alergy and comorbidities. We did not find any differences in therapy response in relation to the type of nutrition (enteral, parenteral) and the administration of immunosupresive drugs. The biological therapy in sporadic and familial Crohn's disease did not differ either. Surgical intervention was more frequent in Crohn's patients compared to the patients with ulcerative colitis; yet no difference was identified between familial and sporadic cases. Appendectomy carried out before the onset of the disease was later diagnosed as Crohn's disease in more instances than ulcerative colitis. CONCLUSION: We did not prove significant differences comparing certain clinical data in familial and sporadic form of inflammatory bowel disease, yet males seem to be more prone to familial Crohn's disease. Small bowel was involved more often in familial form of Crohn's disease than in sporadic form.

BACKGROUND: Confocal laser scanning endomicroscopy (CLSE) enables online in vivo cellular surface and subsurface imaging of normal and pathological tissue at high resolution and magnification. The aim of this study was to work out a method of ex vivo in vitro CLSE in experimental pigs and to compare CLSE images with those of "classic" histology. MATERIAL AND METHODS: Five mature female pigs entered the study. CLSE on an ex vivo in vitro basis was started 10 minutes after pharmacological euthanasia and carried out for 30 minutes. Fluorescein was administrated i.v. as a fluorescence substance. RESULTS: CLSE was successful in all tissue samples of all animals (the oesophagus, stomach, small intestine, large bowel). We have succeeded to obtain high quality images within the first 30 minutes that means 40 minutes after the euthanasia of experimental animals. CLSE images corresponded well with those of haematoxylin-eosin staining. CONCLUSIONS: CLSE on an ex vivo in vitro basis in experimental pigs is feasible.

UNLABELLED: The aim of the study was to evaluate the influence of sliding hiatal hernia over the Barrett's oesophagus, including symptoms rate and complications. METHODS: A total of 520 (4.6%) cases of Barrett's oesophagus were found out of 18.276 upper gastrointestinal endoscopies, performed in 11.276 patients at a single tertiary centre in a period from 1994 to 2004. RESULTS: Sliding hiatal hernia was found in 58% of patients with Barrett's oesophagus, more frequently in men (60%). The association between hernia and some complications of Barrett's oesophagus was significant (94% of Barrett's ulcer, 77% of low-grade dysplasia with p < 0.01). However, there was no significant association with adenocarcinoma (54%; p > 0.05). The other complications of Barrett's oesophagus (i.e. bleeding, stenosis, high-grade dysplasia) were identified in small number (less than 10), so they were not evaluated statistically. Association between the presence of hiatal hernia and occurrence of symptoms (reflux symptoms, dysphagia, odynophagia, dyspeptic and other symptoms) was significant with p < 0.01. CONCLUSIONS: Our study suggests that sliding hiatal hernia may play a significant role as a pathophysiologic factor in Barrett's oesophagus. Complications rate of Barrett's oesophagus were not equally frequent in particular cases with hiatal hernia. The occurrence of symptoms is getting more pronounced in those with sliding hiatal hernia.

Testing antilaminaribioside (ALCA) and antichitobioside (ACCA) antibodies in 89 Crohn's disease (CD), 31 ulcerative colitis (UC) and 50 controls, mean values were 38.6 and 53.0 ELISA units for CD, 34.0 and 32.6 for UC, 34.5 and 36.4 for controls, respectively. There was no significant difference of ALCA values between CD and UC (p = 0.401), CD and control subjects (p = 0.698) or UC and controls (p = 0.898). ACCA were significantly higher in CD compared with UC (p = 0.011) but not with the controls (p = 0.095). No significant difference of ACCA values between UC and controls (p = 0.107) was found. ALCA and ACCA values significantly correlated in CD (r = 0.548, p < 10(-4)) and UC (r = 0.885, p < 10(-4)) but not in controls (r = 0.153, p = 0.287). The positive predictive value for CD was only 20 (ALCA) and 8 % (ACCA), the negative ones (to exclude CD) 25 (ALCA) and 86 % (ACCA). Small and/or large bowel involvement or disease type (i.e. stenosing, perforating or inflammatory) of CD did not differ in the two values. The idea that ALCA and ACCA may be useful either to differentiate between CD, UC and healthy subjects or to stratify CD was not confirmed.

Helicobacter pylori (Hp) is the most common chronic bacterial infection in humans. Hp has been demonstrated worldwide and in individuals of all ages. The overall prevalence of Hp infection has fallen dramatically in the Czech Republic over recent 15 years (from 70% in 1993 to 35% in 2006). This decrease can be explained mostly by the relatively favourable and improving socioeconomic conditions after the fall of communist regime. However, it is necessary to consider also the fundamental determinants of "modern times" that could cause gradual disappearing of Hp from the human "microbiome".

INTRODUCTION: Crohn's disease (CD) and ulcerative colitis (UC) influence women fertility in many ways. OBJECTIVE: We tried to determine the influence of the inflammatory bowel disease on conceiving. The date of the diagnosis, localisation, form and activity at time of conception were involved. DESIGN: Retrospective study. METHODS: We assessed data from 81 patients with inflammatory bowel disease. 56 patients were diagnosed before conceiving (41 with CD, 15 with UC), 25 patients were diagnosed after pregnancy (14 with CD, 11 with UC). We assessed the period of conceiving (in months) depends on previous abdominal operation, localisation, form and activity of the disease at time of conception. The data were obtained from the questionnaire and hospital cards. RESULTS: The previous abdominal operation, the diagnosis, localisation, and the form of the disease did not influence the period necessary to conceive in patient with inflammatory bowel disease. The anoperineal localisation and activity of Crohn's disease at the time of conception extended the period necessary to conceive. CONCLUSION: Fertility of the patients with Crohn's disease depends on the activity of the disease at time of conception and anoperineal involvement. Previous abdominal operation does not influence the fertility.

BACKGROUND: Crohn's disease and ulcerative colitis still remain a heterogeneous group of diseases with an unclear aetiology. Serologic methods play important role in their diagnosing though there is still not an ideal marker. We tried to determine the importance of serological testing of ASCA IgA, IgG, ANCA, ABBA antibodies in patients with ulcerative colitis and Crohn's disease. METHODS AND RESULTS: ASCA IgG, ASCA IgA; ANCA, ABBA antibodies and C-reactive protein were detected by indirect fluorescence assay. ASCA IgA, ASCA IgG, ABBA, ANCA were examined in 40 patients (28 Crohn's disease, 12 ulcerative colitis, 32 health controls). Specificity of ASCA IgA, IgG in CD patients was high (both 96.2%), specificity ANCA in UC 100%. ABBA antibodies had low sensitivity and specificity in both diseases. Combination of ASCA, ANCA, ABBA makes the specificity higher. CONCLUSIONS: We showed the importance of combination ASCA, ANCA with ABBA antibodies to improve the serological diagnosing of IBD.
