Abstract
Irritable bowel syndrome (IBS) and functional dyspepsia are chronic diseases of the digestive tract that challenge both patients and physicians due to their difficult diagnosis and limited treatment options. The international Rome IV diagnostic criteria are commonly used for research purposes. For IBS, the diagnostic criteria based on the German S3 guideline offer a less complicated alternative for everyday clinical practice. A thorough history and basic diagnostic work-up are essential for diagnosis, as reliable biomarkers are still lacking. Clinical manifestations of both disorders are variable, and it has been useful to allocate subtypes based on leading symptom clusters; these may facilitate the choice of diagnostic tests as well as symptomatic treatment approaches. Used correctly, the combination of available drug (mostly off-label) and non-drug options can help to reduce symptoms and improve quality of life.

An expert consensus definition of failure of a treatment to provide adequate relief (F-PAR) for chronic constipation - an international Delphi survey. Aliment Pharmacol Ther 2017; 45:434-442.

Abstract
BACKGROUND As treatments for constipation become increasingly available, it is important to know when to progress along the treatment algorithm if the patient is not better. AIM To establish the definition of failure of a treatment to provide adequate relief (F-PAR) to support this management and referral process in patients with chronic constipation. METHODS We conducted an international Delphi Survey among gastroenterologists and general practitioners with a special interest in chronic constipation. An initial questionnaire based on recognised rating scales was developed following a focus group. Data were collected from two subsequent rounds of questionnaires completed by all authors. Likert scales were used to establish a consensus on a shorter list of more severe symptoms. RESULTS The initial focus group yielded a first round questionnaire with 84 statements. There was good consensus on symptom severity and a clear severity response curve, allowing 67 of the symptom-severity pairings to be eliminated. Subsequently, a clear consensus was established on further reduction to eight symptom statements in the final definition, condensed by the steering committee into five diagnostic statements (after replicate statements had been removed). CONCLUSIONS We present an international consensus on chronic constipation, of five symptoms and their severities, any of which would be sufficient to provide clinical evidence of treatment failure. We also provide data representing an expert calibration of commonly used rating scales, thus allowing results of clinical trials expressed in terms of those scales to be converted into estimates of rates of provision of adequate relief.

Prolonged measurement improves the assessment of the barrier function of the esophago-gastric junction by high-resolution manometry. Neurogastroenterol Motil 2017; 29.

Abstract
BACKGROUND Etiology of gastro-esophageal reflux disease (GERD) is multifactorial, but incompetence of the esophago-gastric junction (EGJ) appears to be of crucial importance. Established manometric parameters for assessment of EGJ barrier function are sub-optimal, potentially because they reflect only a very brief (up to 30 seconds), not necessarily representative period. This prospective, case-control study tested the performance of novel, high-resolution manometry (HRM) parameters of EGJ function in the assessment of GERD. METHODS Patients with reflux symptoms and healthy controls (HC) underwent standard HRM and 24-hour pH±impedance measurements. EGJ morphology, lower esophageal sphincter pressure integral (LES-PI), EGJ contractile integral (EGJ-CI) were compared with total-EGJ-CI, a novel parameter summarizing EGJ barrier function during the entire HRM protocol. Esophageal acid exposure ≥4.2%/24 h (A-Reflux-pos) or ≥73 reflux episodes in 24 hours (V-Reflux-pos) were considered pathological. KEY RESULTS Sixty five HC and 452 patients completed HRM, 380 (84%) patients underwent ambulatory reflux-monitoring. LES-PI, EGJ-CI and total-EGJ-CI correlated with EGJ morphology subtypes (all P<.00001). Only total-EGJ-CI was consistently lower in A-Reflux-pos and V-Reflux-pos subjects compared with HC and patients without GERD. Total-EGJ-CI was also the single best parameter for prediction of pathological reflux (optimal cut-off 47 mmHg cm, AUC 0.746, P<.0001). This cut-off value, approximately 1 SD below the mean normal value, showed modest sensitivity 54% and positive predictive value 46%, but good specificity 85% and negative predictive value 89% for GERD diagnosis. CONCLUSION & INFERENCES Total EGJ-CI, a new metric that summarizes EGJ contractility over time, allows an improved assessment of EGJ barrier function. Pathological reflux is unlikely if this metric is within the upper two-thirds of the normal range.

Abstract
Chronic pancreatitis is a disease of the pancreas in which recurrent inflammatory episodes result in replacement of pancreatic parenchyma by fibrous connective tissue. This fibrotic reorganization of the pancreas leads to a progressive exocrine and endocrine pancreatic insufficiency. In addition, characteristic complications arise, such as pseudocysts, pancreatic duct obstructions, duodenal obstruction, vascular complications, obstruction of the bile ducts, malnutrition and pain syndrome. Pain presents as the main symptom of patients with chronic pancreatitis. Chronic pancreatitis is a risk factor for pancreatic carcinoma. Chronic pancreatitis significantly reduces the quality of life and the life expectancy of affected patients. These guidelines were researched and compiled by 74 representatives from 11 learned societies and their intention is to serve evidence-based professional training as well as continuing education. On this basis they shall improve the medical care of affected patients in both the inpatient and outpatient sector. Chronic pancreatitis requires an adequate diagnostic workup and systematic management, given its severity, frequency, chronicity, and negative impact on the quality of life and life expectancy.

Abstract
Chronic intestinal pseudo-obstruction (CIPO) is the most severe form of intestinal motility disorder, which leads to chronic or intermittent symptoms and signs of (sub-)ileus despite the absence of an intestinal obstruction. Small bowel motility disturbances may occur as primary diseases or secondary to a large number of other diseases and disturbances including rheumatological diseases and neurotoxic drugs. Pathological alterations affect the nervous system, smooth muscles, and/or mesenchymal structures such as the interstitial cells of Cajal or glia cells. Clinical symptoms are unspecific so that the initially suspected diagnosis is almost always wrong. Thus, extensive and stepwise diagnostic procedures are required involving specialized centers in order to exclude intestinal obstruction, to search for complications and potential causes of the disease, to quantify the extension and severity of the motility disorder, and to clarify the pathomechanism if possible. General therapeutic goals include maintenance of adequate nutritional status, improvement of propulsive motility, amelioration of abdominal symptoms, and avoidance and/or therapy of complications. Some CIPO patients require permanent parenteral nutrition. If this causes intolerable complications, small bowel transplantation can be considered in suitable patients as ultima ratio.

Classifying the severity of acute pancreatitis: towards a way forward. Pancreatology 2015; 15:101-4.

Abstract
BACKGROUND The recent development of two different severity classifications for acute pancreatitis has appropriately raised questions about which should be used. The aim of this paper is to review the two new severity classifications, outline their differences, review validation studies, and identify gaps in knowledge to suggest a way forward. METHODS A literature review was performed to identify the purposes and differences between the classifications. Validation studies and those comparing the two different classifications were also reviewed. RESULTS The Revised Atlanta Classification (RAC) and the Determinants Based Classification (DBC) both rely on assessment of local and systemic factors. The differences between the classifications provides opportunities for further research to improve the accuracy and utility of severity classification. This includes understanding how best to tailor severity classification to setting (e.g. secondary or tertiary hospital) and purpose (e.g. clinical management or research). A key difference is that the RAC does not consider infected pancreatic necrosis an indicator of severe disease. There is also the need to develop methods for the accurate non-invasive diagnosis of infected necrosis and evaluation of the characteristics of organ dysfunction in relation to severity and outcome. CONCLUSION Further improvement in severity classification is possible and research priorities have been identified. For now, the decision as to which classification to use should be on the basis of setting, validity, accuracy, and ease of use.

Abstract
BACKGROUND Colonoscopy requires effective bowel preparation for adequate mucosal visualization. Safety and acceptability of bowel preparation are key components in colorectal cancer screening (CRC) populations. OBJECTIVE To compare the efficacy, safety and acceptability of bowel preparation with polyethylene glycol (PEG), ascorbic acid, sodium ascorbate (ascorbate components), sodium sulfate and electrolytes (PEG+Asc) or sodium phosphate (NaP). METHODS Consenting adults undergoing elective out-patient colonoscopy for CRC were randomized to take 2 L PEG+Asc or 90 mL NaP (control) following manufacturer's instructions. PEG+Asc was taken the evening before and morning of the colonoscopy; NaP was taken the morning and evening before colonoscopy. Participants followed a restricted diet specific to each preparation. Primary endpoint was bowel cleansing success (100% colon mucosa visible) rated by an independent expert panel (all experienced endoscopists) unaware of treatment allocations. Subject reported outcomes about the preparations were elicited. Adverse events were recorded. CLINICAL TRIAL REGISTRATION Clinicaltrials.gov: NCT00427089. RESULTS Successful bowel cleansing rate was significantly higher in the PEG+Asc (N = 242) than the NaP (N = 114) group (PEG+Asc 93.4% [95% CI 89.5-96.2] versus NaP 22.8% [15.5-31.6%], p < 0.0001). Subject reported outcomes on acceptability of the two different preparations were not significantly different (p = 0.238). However, taste ratings for PEG+Asc were significantly better versus NaP (mean VAS: 31.2 and 38.1 respectively, p = 0.0111). The proportion of patients prepared to receive the same preparation again was significantly higher in the PEG+Asc group (88.4% vs. 78.1%, p < 0.0001). CONCLUSIONS PEG+Asc provided superior bowel cleansing to NaP and was well tolerated. Findings for PEG+Asc are aligned with previous similar studies; however, differences observed in NaP cleansing results, especially for the proximal colon segments, may be due to factors including: differences in demographics and population types and the use of the validated Harefield Cleansing Scale as an assessment tool combined with expert reviews, which may have resulted in conservative cleansing assessments.

Abstract
MEDICAL HISTORY In a 13-year-old girl regurgitation, constipation and postprandial abdominal pain developed, with decreased nutrient uptake and severe weight loss (BMI 12,6) following a gastroenteritis 2 years before. An eating disorder had been strongly suspected but this diagnosis was not accepted by the family. DIAGNOSTICS Initial investigations including physical investigation, elaborate laboratory tests and imaging techniques showed normal results, but we found transit disturbances and hypotensive motility of the upper gastrointestinal tract. Therapy and course of disease: During prokinetic treatment the girl was asymptomatic for about 9 months, but then the symptoms recurred and no longer responded to drug treatment. Feeding via a jejunal tube because of severe malnutrition was not tolerated either. Refractory vomiting and life-threatening hypokalemia and alkalosis occurred. Imaging techniques now showed marked dilatation of the proximal duodenum. Laparotomy was performed because a Wilkie's syndrome was suspected. However, during the operation mesenterial malrotation was found with adhesive fixation of the distal ileum in the upper left abdomen and compression of the proximal jejunum. The malrotation had been possible because the proximal colon was hypermobile. Following correction of the anatomical situation and retroperitoneal fixation of the colon, oral nutrition was well tolerated. The girl gained weight and remained symptom-free. CONCLUSIONS Not only eating disorders but also defined gastroenterological disturbances may cause weight loss and abdominal symptoms in adolescent girls, even in patients with suggestive symptoms and without pathological findings with routine diagnostics.

Abstract
BACKGROUND Irritable bowel syndrome with constipation (IBS-C) represents a significant burden to patients and healthcare systems due to its prevalence and lack of successful symptomatic resolution with established treatment options. Linaclotide 290 μg has recently been approved by the European Medicines Agency (EMA) for moderate-to-severe IBS-C and by the US Food and Drug Administration for IBS-C (290 μg dose) and for chronic constipation (145 μg dose). AIM To summarise data leading to the approval of linaclotide for IBS-C, with focus on EMA-pre-specified outcome measures. METHODS Literature search of a peer-review database (PubMed) and review of congress abstracts on linaclotide preclinical and clinical trial data in IBS-C. RESULTS Preclinical studies suggest that the guanylate cyclase C agonist (GCCA) linaclotide acts through elevation of cyclic guanosine monophosphate (cGMP) levels, leading to accelerated gastrointestinal (GI) transit through increased fluid secretion and reduced visceral hypersensitivity. Clinical trial data demonstrate that linaclotide improves abdominal symptoms (pain, bloating) and bowel symptoms (constipation) compared with placebo in patients with IBS-C. The most frequent side effect, diarrhoea, results from the therapeutic action of linaclotide. Linaclotide acts locally in the GI tract with minimal systemic exposure, resulting in low oral bioavailability and thus a low risk of relevant systemic adverse effects. CONCLUSION Linaclotide, a first-in-class GCCA, is a promising new drug with a novel, dual mechanism of action that, unlike more well-established agents, can relieve the abdominal pain, bloating and constipation associated with IBS-C and has a low propensity for systemic side effects.

Abstract
AIM The aim of this paper was to present the 2013 Italian edition of a new international classification of acute pancreatitis severity. The Atlanta definitions of acute pancreatitis severity are ingrained in the lexicon of pancreatologists but suboptimal because these definitions are based on empiric description of occurrences that are merely associated with severity. METHODS A personal invitation to contribute to the development of a new international classification of acute pancreatitis severity was sent to all surgeons, gastroenterologists, internists, intensivists, and radiologists who are currently active in clinical research on acute pancreatitis. A global web-based survey was conducted and a dedicated international symposium was organized to bring contributors from different disciplines together and discuss the concept and definitions. RESULTS The new international classification is based on the actual local and systemic determinants of severity, rather than description of events that are correlated with severity. The local determinant relates to whether there is (peri)pancreatic necrosis or not, and if present, whether it is sterile or infected. The systemic determinant relates to whether there is organ failure or not, and if present, whether it is transient or persistent. The presence of one determinant can modify the effect of another such that the presence of both infected (peri)pancreatic necrosis and persistent organ failure have a greater effect on severity than either determinant alone. The derivation of a classification based on the above principles results in 4 categories of severity-mild, moderate, severe, and critical. CONCLUSION This classification provides a set of concise up-to-date definitions of all the main entities pertinent to classifying the severity of acute pancreatitis in clinical practice and research.

Abstract
Functional dyspepsia (FD) and irritable bowel syndrome (IBS) are the most important functional gastrointestinal diseases (FGID), and both affect about 5-15 % of the German population. The patients' symptoms are caused by disturbances of gastrointestinal (GI) motility, secretion and sensitivity. Central processing of visceral afferences is disturbed, and the course of the disease and individual symptom perception are influenced by psychosocial factors. Diagnosis of FD and IBS is based on a compatible symptom pattern, absence of alarm symptoms and exclusion of relevant differential diagnoses. The diagnosis of FD requires a normal upper GI endoscopy. Current German guidelines also demand a normal colonoscopy for diagnosis of IBS. Basic therapeutic measures include explanation of the nature of the disease and its harmlessness quo ad vitam . Individual trigger factors should be identified and eliminated if possible. Drug therapy of persisting complaints is guided by the dominant symptom.

Abstract
OBJECTIVE To develop a new classification of acute pancreatitis severity on the basis of a sound conceptual framework, comprehensive review of the published evidence, and worldwide consultation. BACKGROUNDS The Atlanta definitions of acute pancreatitis severity are ingrained in the lexicon of specialist in pancreatic diseases, but are suboptimal because these definitions are based on the empiric description of events not associated with severity. METHODS A personal invitation to contribute to the development of a new classification of acute pancreatitis severity was sent to all surgeons, gastroenterologists, internists, intensivists and radiologists currently active in the field of clinical acute pancreatitis. The invitation was not limited to members of certain associations or residents of certain countries. A global web-based survey was conducted, and a dedicated international symposium was organized to bring contributors from different disciplines together and discuss the concept and definitions. RESULTS The new classification of severity is based on the actual local and systemic determinants of severity, rather than on the description of events that are non-causally associated with severity. The local determinant relates to whether there is (peri) pancreatic necrosis or not, and if present, whether it is sterile or infected. The systemic determinant relates to whether there is organ failure or not, and if present, whether it is transient or persistent. The presence of one determinant can modify the effect of another, whereby the presence of both infected (peri) pancreatic necrosis and persistent organ failure has a greater impact upon severity than either determinant alone. The derivation of a classification based on the above principles results in four categories of severity: mild, moderate, severe, and critical. CONCLUSIONS This classification is the result of a consultative process among specialists in pancreatic diseases from 49 countries spanning North America, South America, Europe, Asia, Oceania and Africa. It provides a set of concise up to date definitions of all the main entities pertinent to classifying the severity of acute pancreatitis in clinical practice and research. This ensures that the determinant-based classification can be used in a uniform manner throughout the world.

HISTORY AND CLINICAL FINDINGS A 14-year-old boy was admitted to hospital because of chronic episodic diarrhea lasting for 4 years. Previous investigations in the past had not revealed the cause of the symptoms. INVESTIGATIONS The 13C-triglyceride breathing test showed a diminished intestinal lipolysis. Endoscopic examination demonstrated small gastroduodenic ulcers. During therapy with proton-pump inhibitors the diarrhea stopped. DIAGNOSIS, TREATMENT AND COURSE The combination of gastroduodenic ulcers and improvement of diarrhea with PPI-therapy were suggestive of Zollinger-Ellison syndrome. Endosonography and MR-scan showed an extrapancreatic mass with marked activity during somatostatin receptor scintigraphy. The primary tumor was excised, a liver metastasis was treated with radiofrequency ablation. The histological examination confirmed the diagnosis of a gastrinoma. CONCLUSION In patients with chronic diarrhea, especially if the symptoms are PPI-sensitive, a gastrinoma should be considered.

Abstract
The treatment of patients with inflammatory bowel disease has become more complex in recent years through the introduction of various immunosuppressive agents as well as the approval of monoclonal antibodies. Patients receiving such treatment must be carefully monitored. National and international guidelines define a diagnostic and therapeutic context for the practitioner, but can only partially respond to specific questions on the procedure for individual patients. Within the framework of a project initiated by Abbott entitled "IBD ahead" 34 German IBD experts have elaborated concrete proposals for the utility of clinical symptom assessment, endoscopy and the use of laboratory parameters including foecal markers of inflammation. Furthermore, we discuss the significance of conventional X-rays, computed tomography, ultrasound and magnetic resonance tomography. These recommendations are illustrated by case studies from everyday practice in the participating centres.

Abstract
BACKGROUND Previous reviews of bowel preparation for colonoscopy have given contradictory answers. AIM To provide a definitive insight, using PRISMA-compliant methodology. METHODS A comprehensive literature review identified randomised controlled trials comparing bowel preparation regimens. Data for quality of bowel preparation were pooled in multiple meta-analyses exploring a range of inclusion criteria. RESULTS A total of 104 qualifying studies were identified, the majority of which involved comparisons of sodium phosphate (NaP) or polyethylene glycol (PEG). There was no significant difference demonstrated between NaP and PEG overall (OR = 0.82; 95% CI = 0.56-1.21; P = 0.36). Cumulative meta-analysis demonstrated that this conclusion has been qualitatively similar since the mid 1990s, with little quantitative change for the past 10 years. Amongst studies with previous day dosing in both study arms there was a significant advantage in favour of PEG (OR = 1.78; 95% CI = 1.13-2.81; P = 0.006). Studies focussing on results in the proximal colon also favoured PEG (OR = 2.36; 95% CI = 1.16-4.77; P = 0.012). PEG was also significantly more effective than non-NaP bowel preparation regimens (OR = 2.02; 95% CI = 1.08-3.78; P = 0.03). Other comparisons showed no significant difference between regimens. CONCLUSIONS Although there is no compelling evidence favouring either of the two most commonly used bowel preparation regimens, this may reflect shortcomings in study design. Where studies have ensured comparable dosage, or the clinically relevant outcome of proximal bowel clearance is considered, PEG-based regimens offer the most effective option.

Abstract
The treatment of patients with inflammatory bowel disease has become more complex in recent years through the introduction of various immunosuppressive agents as well as the approval of monoclonal antibodies against TNF-α and patients receiving such treatment must be carefully monitored. National and international guidelines define a diagnostic and therapeutic context for the practitioner, but can only partially respond to specific questions on the procedure for individual patients. Within the framework of a project initiated by Abbott entitled "IBD ahead" 38 German IBD experts have elaborated concrete proposals for dealing with corticosteroids, immunosuppressants and TNF-α antibodies on the basis of the published literature and their own personal experience in order to close the gap between these guidelines and daily clinical practice. Statements were developed on the choice of correct timing of initiation, dose and duration of the individual substances and on how to proceed with patients exhibiting treatment failure. Moreover, recommendations are also made on drug combination strategies, safety monitoring and the risks regarding the development of infectious complications and malignancies. These recommendations are illustrated by case studies from everyday practice in participating centres.

Abstract
We report a case of acinar cell carcinoma of the pancreas associated with excessively elevated levels of serum alpha-fetoprotein (>32,000 ng/ml). Abdominal computed tomography scan revealed a large pancreatic mass with infiltration of the splenic artery. Because of inoperability, palliative combination chemotherapy with gemcitabine and mitomycin C was administered. This regimen was associated with clinical improvement and dramatic decreases in both tumor size and serum alpha-fetoprotein. However, the patient died 7 months later from acute severe cardiac failure.

Abstract
The irritable bowel syndrome is the most frequent and most important functional bowel disease. It is characterized by a combination of abdominal pain, alterations of bowel habits (diarrhea, constipation) and meteorism. Probably, visceral hypersensitivity, motility disturbances, food intolerance, immunologic and microbiologic alterations and psychosomatic influences contribute to symptoms. In a relevant subgroup of patients the disease is triggered by bacterial infection. These patients usually have diarrhea-predominant disease. Irritable bowel syndrome can be diagnosed if typical symptoms are present and after relevant organic differential diagnoses have been excluded by selective biochemical investigations, abdominal ultrasonography and, if applicable, by colonoscopy. These diagnostic procedures are an important basis for therapeutic interventions and need to be complemented by clear information about the diagnosis and the benign long-term course of the disease. Medical therapy concentrates on treatment of predominant symptoms, i.e. pain, diarrhea, constipation and meteorism.

Abstract
Diagnostic techniques investigating intestinal functions are a main component of gastroenterological diagnostic procedures and are mainly indicated if intestinal motility disturbances or malabsorption syndromes are suspected. H2 breath tests using lactulose or lactitol as substrates measure orocecal transit time. Intestinal manometry allows more detailed analysis of intestinal motility disturbances but is only available at specialized centres. A generalized malabsorption syndrome can be diagnosed by D-xylose test. If it is caused by bacterial overgrowth, the H2 breath test with glucose may be helpful. Lactose intolerance is the most frequently observed intestinal malfunction and affects about 70% of people worldwide. At present, the lactose H2 breath test is the diagnostic procedure of choice to prove lactose malabsorption. Clinically relevant insufficiencies of other intestinal disaccharidases are rare, but may indicate H2 breath tests with specific substrates. Recently developed 13C breath tests using stable, non-radioactive substrates may extend our diagnostic options considerably and may allow more detailed information about intestinal (mal-)functions as a prerequisite for optimized therapy.

Abstract
AIM To assess whether the eradication of Helicobacter pylori leads to long-term relief of symptoms in functional dyspepsia. METHODS Eight hundred patients with functional dyspepsia were randomized to receive double-blind treatment with twice-daily 30 mg lansoprazole, 1000 mg amoxicillin and 500 mg clarithromycin for 7 days (L30AC), twice-daily 15 mg lansoprazole, 1000 mg amoxicillin and 500 mg clarithromycin for 7 days (L15AC), or once-daily 15 mg lansoprazole for 14 days (LP). Dyspepsia and reflux symptoms were monitored for 12 months. RESULTS In intention-to-treat analysis, the non-ulcer dyspepsia sum score showed a statistically significant benefit in terms of symptom relief in the L30AC group (P = 0.0068) compared with the LP group, but there was no significant difference between the L15AC and LP groups (P = 0.2). When all patients in the two eradication therapy arms were considered together, successful eradication had a significant benefit with regard to the complete absence of symptoms (P < 0.04). H. pylori eradication did not lead to an increase in reflux symptoms. CONCLUSION This study suggests that H. pylori infection causes dyspeptic symptoms in a subset of patients with functional dyspepsia, and that these patients may obtain long-term symptomatic benefit following H. pylori eradication.

Abstract
In the treatment of the irritable bowel syndrome, it is important to qualify unrealistic expectations with regard to treatment, at an early stage. The therapeutic spectrum encompasses establishment of good rapport between physician and patient, modification of life style, provision of good patient information, reassurance, coping strategies, and temporal restraints on medication. Depending on the leading symptoms, the latter may range from laxatives to probiotics, anticholinergics or spasmolytics, prokinetic and anti-diarrheal agents, to 5-HT3/HT4 receptor antagonists. In individual patients with frequently recurrent or permanent pain, the use of tricyclic antidepressants may be considered. Painkillers should be reserved for patients in whom other therapeutic strategies have failed.

Abstract
Its high prevalence, chronic course, sometimes very troubling symptoms and rather limited therapeutic options, make the irritable bowel syndrome (IBS) one of the most common conditions seen by the family doctor, internist and gastroenterologist. IBS is characterized by abdominal pain accompanied by altered bowel movements and a facultative association with abdominal distension. IBS runs a chronic recurrent course punctuated by relatively symptom-free phases, and an overall good prognosis for survival (quoad vitam). Visceral hypersensitivity, altered gastrointestinal motility, psychosocial factors, and neurotransmitter imbalance are under discussion as underlying pathophysiology. An orienting medical history, clinical examination and exclusion of such alarm symptoms as weight loss, general debility and rectal bleeding, must be followed by a rational choice of further diagnostic measures.

Abstract
BACKGROUND Nissen fundoplication (360 degrees ) is the standard operation for the surgical management of gastroesophageal reflux disease (GERD). To avoid postoperative dysphagia, it has been proposed that antireflux surgery be tailored according to the degree of preexisting esophageal motility. Postoperative dysphagia is thought to occur more commonly in patients with esophageal dysmotility and the Toupet procedure (270 degrees ) has been recommended for these patients. We performed a randomized trial to evaluate this tailored concept and to compare the two operative techniques in terms of reflux control and complication rate (dysphagia). Our objective was to determine the impact of preoperative esophageal motility on the clinical and objective outcome, following Toupet vs Nissen fundoplication and to evaluate the success rate of these procedures. METHODS From May 1999 until May 2000, 200 patients with GERD were included in a prospective randomized study. After preoperative examinations (clinical interview, endoscopy, 24-h pH study and esophageal manometry), 100 patients underwent either a laparoscopic Nissen (50 with and 50 without motility disorders), or a Toupet procedure (50 with and 50 without motility disorders). Postoperative follow-up after 4 months included clinical interview, endoscopy, 24-h pH study and esophageal manometry. RESULTS Interviews showed that 88% (Nissen) and 90% (Toupet) of the patients, respectively, were satisfied with the operative result. Dysphagia was more frequent following a Nissen fundoplication than after a Toupet (30 vs 11, p <0.001) and did not correlate with preoperative motility. In terms of reflux control, the Toupet proved to be as effective as the Nissen procedure. CONCLUSION Tailoring antireflux surgery to esophageal motility is not indicated, since motility disorders are not correlated with postoperative dysphagia. The Toupet procedure is the better operation because it has a lower rate of dysphagia and is as effective as the Nissen fundoplication in controlling reflux.

Abstract
Chronic intestinal pseudo-obstruction (CIPO) is a rare disease in which a severe intestinal motility disorder impairs transit of chyme so that patients suffer from symptoms of a mechanical ileus without mechanical obstruction. CIPO may be a primary or secondary disorder due to muscular, neurologic, metabolic or endocrine disorders, but may also occur postinfectiously, postoperatively, following abdominal radiation or be caused by drugs or noxae. In severe cases, the typical history of (repeated) symptoms of mechanical obstruction leading to unsuccessful laparotomies will give key clues for diagnosis. If CIPO is suspected, mechanical obstruction must be searched for carefully by radiologic and endoscopic examinations. Histologic diagnosis usually demands full thickness biopsies of the intestinal wall. Small intestinal manometry allows diagnosis of CIPO even during oligosymptomatic intervals as well as differentiation between neuropathic and myopathic forms of the disease. The main therapeutic goals consist in: 1. Maintenance of an adequate nutritional state by oral and/or enteral nutrition; in severe cases home-parenteral nutrition may be required and particularly in children intestinal transplantation may be the ultima ratio. 2. Reconstitution of intestinal propulsion by prokinetic drugs. 3. Therapy of complications such as bacterial overgrowth and severe pain by antibiotics and specific surgical procedures. Unnecessary laparotomies should be strictly avoided because they may lead to adhesions and markedly complicate the clinical course.
