Abstract
OBJECTIVES Autism spectrum disorder is a neurodevelopmental condition that typically displays socio-communicative impairment as well as restricted stereotyped interests and activities, in which gastrointestinal disturbances are commonly reported. We report the case of a boy with Autism Spectrum Disorder (ASD) diagnosis, severe cognitive disability and celiac disease in which an unexpected improvement of autistic core symptoms was observed after four months of probiotic treatment. METHOD The case study refers to a 12 years old boy with ASD and severe cognitive disability attending the Villa Santa Maria Institute in resident care since 2009. Diagnosis of ASDs according to DSM-V criteria was confirmed by ADOS-2 assessment (Autism Diagnostic Observation Schedule). The medication used was VSL#3, a multi-strain mixture of ten probiotics. The treatment lasted 4 weeks followed by a four month follow-up. The rehabilitation program and the diet was maintained stable in the treatment period and in the follow up. ADOS-2 was assessed six times: two times before starting treatment; two times during the treatment and two times after interruption of the treatment. RESULTS The probiotic treatment reduced the severity of abdominal symptoms as expected but an improvement in Autistic core symptoms was unexpectedly clinically evident already after few weeks from probiotic treatment start. The score of Social Affect domain of ADOS improved changing from 20 to 18 after two months treatment with a further reduction of 1 point in the following two months. The level 17 of severity remained stable in the follow up period. It is well known that ADOS score does not fluctuate spontaneously along time in ASD and is absolutely stable. CONCLUSIONS The appropriate use of probiotics deserves further research, which hopefully will open new avenues in the fight against ASD.

Abstract
BACKGROUND & AIMS Computed tomographic colonography (CTC) is a reliable option for screening subjects who are unable or unwilling to undergo optical colonoscopy (OC). A colon capsule (PillCam Colon2 [CC2]; GivenImaging Ltd., Yokneam, Israel) has shown promising results in detecting polyps larger than 6 mm. We compared the accuracy of CC2 and CTC in identifying individuals with at least 1 polyp greater than 6 mm and subjects' attitude toward the procedures. METHODS Fifty individuals (mean age, 59.2 ± 5.8 y; 58% male) with positive results from the immunochemical fecal occult blood test (iFOBT-positive) underwent CC2, CTC, and OC. The unblinded colonoscopy, integrating OC, CTC, and CC2 results, was used as the reference standard. In a per-patient analysis, the accuracy of CC2 and CTC were assessed for individuals with at least 1 polyp 6 mm or larger. Individuals were asked to choose which procedure they would be willing to repeat between CTC and CC2. RESULTS The combination of OC, CTC, and CC2 identified 16 cases with at least 1 polyp 6 mm or larger (reference standard). CTC identified the polyps with 88.2% sensitivity, 84.8% specificity, a 3.0 positive likelihood ratio, and a 0.07 negative likelihood ratio. CC2 identified the polyps with 88.2% sensitivity, 87.8% specificity, a 3.75 positive likelihood ratio, and a 0.06 negative likelihood ratio. Thirty-nine subjects (78%) said they preferred CC2 to CTC. CONCLUSIONS CC2 and CTC detect polyps 6 mm and larger with high levels of accuracy; these techniques are effective in selecting iFOBT-positive individuals who do not need to be referred for colonoscopy. CC2 seems to be better tolerated than CTC, and could be a reliable alternative to CTC for iFOBT-positive individuals who are unable or unwilling to undergo OC. ClinicalTrials.gov number: NCT01744509.

Abstract
BACKGROUND Hyoscine N-butylbromide (HBB), commonly used during colonoscopy to facilitate cecal intubation, has been proposed to increase the adenoma detection rate (ADR). AIMS To evaluate whether HBB administration increases the adenoma detection rate and influences patients' tolerance. METHODS Consecutive colonoscopy outpatients were randomized after cecal intubation to receive either 20mg HBB or placebo i.v. The number, size, histology and location of polyps were recorded. The air retained in the abdomen was either indirectly estimated by ΔAC (difference in the abdominal circumference measured before and after colonoscopy) or directly evaluated by patients' perception (visual analogic scale, range 0-100). RESULTS 402 patients (44% male; mean age 57.7±12.5years) received either HBB or placebo. No differences in ADR (31.7% vs. 28%, p=0.48), advanced-ADR (7.4% vs. 10.5%, p=0.35) were observed between HBB and placebo group, respectively. A significantly lower detection rate of flat/depressed lesions was observed in the HBB group (0.5% vs. 5.5%, p=0.003). The ΔAC and the bloating perception were comparable between the two groups (p=0.22 and p=0.48, respectively). CONCLUSIONS HBB administered before colonoscope withdrawal does not increase adenoma detection rate and seems to hamper the visualization of flat/depressed lesions. This finding raises concerns on the indiscriminate use of HBB during colonoscopy.

Abstract
BACKGROUND Not much is known about errors and near misses in digestive endoscopy. AIMS To verify whether an incident report, with certain facilitating features, gives useful information about unintended events, only excluding errors in medical diagnosis. METHOD Nine endoscopy units took part in this cross sectional, prospective, multicentre study which lasted for two weeks. Members of the staff were required to report any unintended, potentially dangerous event observed during the daily work. A form was provided with a list of "reminders" and facilitators were appointed to help. The main outcome measurements were type of event, causes, corrective interventions, stage of occurrence in the workflow and qualification of the reporters. RESULTS A total of 232 errors were reported (two were not related to endoscopy). The remaining 230 amount to 10.3% of 2239 procedures; 66 (29%) were considered errors with consequences, 164 (71%) "near misses". There were 150 pre-operative errors (65%), 22 operative (10%) and 58 post-operative (25%). Corrective interventions were provided for 60 cases of errors and 119 near misses. Most of the events were reported by the nurses (106 out of 232, 46%). CONCLUSIONS Short-term incident reporting focusing on near misses, using forms with lists of "reminders", and the help of a facilitator, can give useful information on errors and near misses in digestive endoscopy.

Abstract
BACKGROUND AND STUDY AIMS Narrow-band imaging (NBI) has shown promising results in discriminating adenomatous from non-adenomatous colonic polyps. In patients with small polyps (< 10 mm), the application of NBI within a "resect and discard" strategy, might allow post-polypectomy surveillance intervals to be determined independently from histopathology. The aim of the present study was to assess the feasibility and safety of this approach in routine clinical practice. PATIENTS AND METHODS Consecutive colonoscopy outpatients with one or more polyps smaller than 10 mm were prospectively included. Each polyp was categorized by the endoscopist as adenoma or non-adenoma according to simplified NBI criteria, and future post-polypectomy surveillance interval was assigned accordingly. Following histopathology, post-polypectomy surveillance interval was subsequently re-assigned, and the accordance between endoscopy- and histology-directed surveillance strategies was calculated. RESULTS Among 942 colonoscopy patients, 286 (30.4 %) with only small polyps were included. In total, 511 small polyps were evaluated; 350 (68.5 %) were adenomas and 18 of these (5.1 %) had histologic features of advanced neoplasia. For the in vivo diagnosis of adenoma, NBI sensitivity, specificity, accuracy, and positive and negative likelihood ratios were 94.9 %, 65.8 %, 85.7 %, 2.80, and 0.08, respectively. The endoscopy-directed surveillance strategy was in accordance with the histology-directed strategy in 237 of 286 patients (82.9 %). In 9.8 % and 7.3 % patients, the endoscopy-directed approach would have resulted in early and delayed surveillance, respectively. CONCLUSIONS The resect and discard strategy seems to be a viable, safe, and cost-effective approach for the management of patients with small polyps. However, caution in the application of the strategy should be advocated for patients with polyps 6 - 9 mm in size and those with right-sided lesions, due to their malignant potential. The study was registered on Clinicaltrials.gov (NCT01462123).

Abstract
BACKGROUND Water-aided methods for colonoscopy are distinguished by the timing of removal of infused water, predominantly during withdrawal (water immersion) or during insertion (water exchange). OBJECTIVE To discuss the impact of these approaches on colonoscopy pain and adenoma detection rate (ADR). DESIGN Systematic review. SETTING Randomized, controlled trial (RCT) that compared water-aided methods and air insufflation during colonoscope insertion. PATIENTS Patients undergoing colonoscopy. INTERVENTION Medline, PubMed, and Google searches (January 2008-December 2011) and personal communications of manuscripts in press were considered to identify appropriate RCTs. MAIN OUTCOME MEASUREMENTS Pain during colonoscopy and ADR. RCTs were grouped according to whether water immersion or water exchange was used. Reported pain scores and ADR were tabulated based on group assignment. RESULTS Pain during colonoscopy is significantly reduced by both water immersion and water exchange compared with traditional air insufflation. The reduction in pain scores was qualitatively greater with water exchange as compared with water immersion. A mixed pattern of increases and decreases in ADR was observed with water immersion. A higher ADR, especially proximal to the splenic flexure, was obtained when water exchange was implemented. LIMITATIONS Differences in the reports limit application of meta-analysis. The inability to blind the colonoscopists exposed the observations to uncertain bias. CONCLUSION Compared with air insufflation, both water immersion and water exchange significantly reduce colonoscopy pain. Water exchange may be superior to water immersion in minimizing colonoscopy discomfort and in increasing ADR. A head-to-head comparison of these 3 approaches is required.

Abstract
Although sedation and analgesia for patients undergoing colonoscopy is the standard practice in Western countries, unsedated colonoscopy is still routinely provided in Europe and the Far East. This variation in sedation practice relies on the different cultural attitudes of both patients and endoscopists across these countries. Data from the literature consistently report that, in unsedated patients, the use of alternative techniques, such as warm water irrigation or carbon dioxide insufflation, can allow a high quality and well tolerated examination.

Abstract
BACKGROUND The increasing request for colonoscopy in clinical practice, coupled with the lack of time, has led to a renewed interest in unsedated procedures. OBJECTIVE To evaluate the acceptability of unsedated colonoscopy and to characterize the subset of patients more likely to undergo and complete the procedure without sedation and/or analgesia. DESIGN Prospective, population study. SETTING Nonacademic community hospital, 6-month observation period. PATIENTS Adult outpatients referred for colonoscopy were offered unsedated procedure, with the possibility of on-demand sedation. INTERVENTIONS Demographics, clinical features, and endoscopy outcomes were recorded. Data were analyzed by stepwise logistic regression analysis, and odds ratio (OR) and 95% confidence interval (CI) are given for significant variables. MAIN OUTCOME MEASUREMENTS Unsedated colonoscopy acceptance rate. Factors significantly associated with acceptance and completion of unsedated procedures. RESULTS The acceptance rate for unsedated colonoscopy was 56.2% of 964 consecutive evaluated patients. The cecal intubation rate in unsedated patients was 81.6% and increased to 97.3% with the option of on-demand sedation. At multivariate analysis, factors significantly associated with the acceptance were no previous colonoscopy (OR 1.52; 95% CI, 1.10-2.11), absent/low level of anxiety (OR 3.82; 95% CI, 2.71-5.38), and no concern about the examination (OR 1.80; 95% CI, 1.17-2.77). Fear of procedure-related pain was inversely associated with acceptance (OR 0.28; 95% CI, 0.17-0.35). Factors associated to drug-free colonoscopy completion were absence of preprocedure anxiety (OR 1.87; 95% CI, 1.08-3.21) and male sex (OR 3.59; 95% CI, 2.13-6.05). LIMITATIONS Single-center study. CONCLUSION The acceptance rate of unsedated colonoscopy is clinically relevant, and the procedure can be completed without sedation in the majority of patients. Subject-related factors may help to identify patients willing to undergo and potentially complete unsedated procedures.

Abstract
INTRODUCTION: Variation in outcomes in RcTs comparing water-related methods and air insufflation raises challenging questions regarding the new approach. This report reviews impact of water exchange - simultaneous infusion and removal of infused water during insertion on adenoma detection rate (ADR) defined as proportion of patients with a least one adenoma of any size. METHODS: Medline (2008-2011) searches, abstract of 2011 Digestive Disease Week (DDW) meeting and personal communications were considered to identify RcTs that compared water-related methods and air insufflation to aid insertion of colonoscope. RESULTS: Since 2008, eleven reports of RcTs (6 published, 1 submitted and 4 abstracts, n=1728) described ADR in patients randomized to be examined by air and water-related methods. The water-related methods differed in timing of removal of the infused water -predominantly during insertion (water exchange) (n=825) or predominantly during withdrawal (water immersion) (n=903). Water immersion was associated with both increases and decreases in ADR compared to respective air method patients and the net overall change (-7%) was significant. On the other hand water exchange was associated with increases in ADR consistently and the net changes (overall, 8%; proximal overall, 11%; and proximal <10 mm, 12%) were all significant. CONCLUSION: Comparative data generated the hypothesis that significantly larger increases in overall and proximal colon ADRs were associated with water exchange than water immersion or air insufflation during insertion. The hypothesis should be evaluated by RCTs to elucidate the mechanism of water exchange on adenoma detection.

Abstract
INTRODUCTION: Variation in the outcomes in RcTs comparing water-related methods and air insufflation during the insertion phase of colonoscopy raises challenging questions regarding the approach. This report reviews the impact of water exchange on the variation in attenuation of pain during colonoscopy by water-related methods. METHODS: Medline (2008 to 2011) searches, abstracts of the 2011 Digestive Disease Week (DDW) and personal communications were considered to identify RcTs that compared water-related methods and air insufflation to aid insertion of the colonoscope. Results: Since 2008 nine published and one submitted RcTs and five abstracts of RcTs presented at the 2011 DDW have been identified. Thirteen RcTs (nine published, one submitted and one abstract, n=1850) described reduction of pain score during or after colonoscopy (eleven reported statistical significance); the remaining reports described lower doses of medication used, or lower proportion of patients experiencing severe pain in colonoscopy performed with water-related methods compared with air insufflation (Tables 1 and 2). The water-related methods notably differ in the timing of removal of the infused water - predominantly during insertion (water exchange) versus predominantly during withdrawal (water immersion). Use of water exchange was consistently associated with a greater attenuation of pain score in patients who did not receive full sedation (Table 3). CONCLUSION: The comparative data reveal that a greater attenuation of pain was associated with water exchange than water immersion during insertion. The intriguing results should be subjected to further evaluation by additional RcTs to elucidate the mechanism of the pain-alleviating impact of the water method.

Abstract
BACKGROUND Uncontrolled data suggest that warm water infusion (WWI) instead of air insufflation (AI) during the insertion phase of unsedated colonoscopy improves patient tolerance and satisfaction. OBJECTIVE We tested the hypothesis that water could increase the proportion of patients able to complete unsedated colonoscopy and improve patient tolerance compared with the conventional procedure. DESIGN Randomized, controlled trial. SETTING Single center, community hospital. PATIENTS Consecutive outpatients agreeing to start colonoscopy without premedication. METHODS Patients were randomly assigned to either WWI or AI insertion phase of colonoscopy. Sedation and/or analgesia were administered on patient request if significant pain or discomfort occurred. MAIN OUTCOME MEASUREMENTS Percentage of patients requiring sedation/analgesia. Pain and tolerance scores were assessed at discharge by using a 100-mm visual analog scale. RESULTS A total of 230 subjects (116 in the WWI group and 114 in the AI group) were enrolled. Intention-to-treat analysis showed that the proportion of patients requesting sedation/analgesia during the procedure (main outcome measurement) was 12.9% in the WWI group and 21.9% in AI group (P = .07). Cecal intubation rates were 94% in the WWI group and 95.6% in the AI group (P = .57). Median (interquartile range) scores for pain were 28 (12-44) and 39 (14-54) in WWI and AI groups, respectively (P = .05); corresponding figures for tolerance were 10 (3-18) and 14 (5-42), respectively (P = .01). The adenoma detection rates were 25% and 40.1% for the WWI and AI groups, respectively (P = .013). LIMITATIONS Single-center study, endoscopists not blinded to randomization. CONCLUSIONS WWI instead of AI is not associated with a statistically significant decrease in the number of patients requiring on-demand sedation, although it significantly improves the overall patient tolerance of colonoscopy. The finding of a lower adenoma detection rate in the WWI group calls for further evaluations. ( CLINICAL TRIAL REGISTRATION NUMBER NCT00905554).

Abstract
OBJECTIVES Patients' compliance with and tolerance of large-volume polyethylene glycol electrolyte solution (PEG-ES) have prompted continuous investigation with alternative forms of cleansing. High-dose senna is superior to PEG-ES for the quality of bowel cleansing, patient compliance, and tolerance, but its acceptance may be influenced by the incidence of abdominal pain. We hypothesized that a combination of half doses of PEG-ES and senna could minimize the incidence of abdominal pain without affecting the quality of bowel preparation. METHODS This randomized, investigator-blinded trial has been conducted on consecutive outpatients scheduled for elective colonoscopy at a single community-based hospital. Patients were randomly assigned to receive either 12 tablets of 12 mg senna and 2 l of PEG-ES (half-dose group, HDG) or 24 tablets of senna divided in two doses (senna group, SG) the day before colonoscopy. The main outcome measures were the quality of colon cleansing (Aronchick scoring scale) and the incidence of preparation-related abdominal pain. Secondary outcome measures were patients' compliance with the cleansing regimen, overall tolerability, prevalence of predefined side effects, and quality of right colon cleansing. RESULTS A total of 296 patients were enrolled (HDG=151 and SG=145). Overall cleansing was excellent to good in 90.1 and 88.3% patients in HDG and SG, respectively (P=0.62). Preparation-related moderate-to-severe abdominal pain was reported by 6% patients in HDG and 15.2% in SG (P=0.009). No significant differences were observed for secondary outcomes. CONCLUSIONS The regimen combining half doses of PEG-ES and senna provides high-quality bowel preparation and acceptable patient tolerance, with less abdominal pain compared with high-dose senna.

Abstract
Constipation is a highly prevalent and bothersome disorder that negatively affects patients' social and professional lives and places a great economic burden on both patients and national health services. An accurate determination of the prevalence of constipation is difficult because of the various definitions used, but many epidemiological studies have shown that it affects up to 20% of the population at any one time. Although constipation is not a physiological consequence of normal aging, decreased mobility and other co-morbid medical conditions may contribute to its prevalence in older adults. Functional constipation is diagnosed when no secondary causes can be identified. Patients have some unusual beliefs about their bowel habits. Systematic attention to history, examination and investigation, especially in older people, can be highly effective in resolving problems and in enhancing quality of life. There is a considerable range of treatment modalities available for patients with constipation, but the clinical evidence supporting their use varies widely. However, if constipation is not managed proactively, patients can experience negative consequences, such as anorexia, nausea, bowel impaction or bowel perforation. The clinical benefits of various traditional pharmacological and non-pharmacological agents remain unclear. The first steps in the treatment of simple constipation include increasing intake of dietary fibre and the use of a fibre supplement. Patients with severe constipation or those unable to comply with the recommended intake of fibre may benefit from the addition of laxatives. More recently, newer agents (e.g. tegaserod and lubiprostone), have been approved for the treatment of patients with chronic constipation. Additional work is needed to determine what role, if any, these agents may play in the treatment of patients with chronic constipation. The purpose of this review is to identify evidence-based interventions for the prevention and management of constipation in the elderly.

Abstract
BACKGROUND AND STUDY AIMS To study the effectiveness of endoscopic treatment for biliary stones in a large case list of patients treated in units with different experience and different workloads in a region of northern Italy. PATIENTS AND METHODS We prospectively studied 700 patients undergoing endoscopic retrograde cholangiopancreatography or sphincterotomy, in 14 units (> or < 200 examinations/year), for their first treatment of biliary stones. The difficulty of the examinations, the results in terms of clearance of the stones, and the late outcomes (24 months) were recorded. A questionnaire (GHAA-9modified) was administered 24 hours and 30 days after the procedure to measure patient satisfaction. RESULTS There were six units with a heavy workload and eight with a light schedule. There were 176 (25.1 %) difficult examinations (Schutz grades 3, 4, and 5). Stones were found in 580 (82.9 %) and were cleared in 504 of these patients (86.9 %). No differences were observed in the clearance of stones for the different groups of difficulty and high- and low-volume centers. Over the 24-month follow-up period, 96 patients (13.7 %) complained of recurrent symptoms and 44 (6.3 %) had proof of stones. In all, 603 questionnaires were evaluable and more than 80 % of patients expressed satisfaction. CONCLUSIONS Our findings confirm the effectiveness of endoscopic treatment of biliary stones. However, the number of patients with symptoms (13.7) after 24 months, with or without persistence of stones, was not insignificant. It is feasible to record patient satisfaction, and in this series patients stated they were satisfied. Criticism mostly concerned pain control and explanations provided before the examination.

Abstract
BACKGROUND AND STUDY AIM Continuous quality improvement (CQI) is recommended by professional societies as part of every colonoscopy program, but little is known with regard to its effectiveness for colonoscopy outcomes. We prospectively assessed whether the implementation of a CQI program in routine clinical practice influences the quality performance of colonoscopy. METHODS In an open-access endoscopy unit at a secondary care center in Northern Italy, 6-monthly audit cycles were carried out over a 4-year period, to identify reasons for poor colonoscopy outcomes and institute appropriate changes to improve performance. The colonoscopy completion rate and the polyp detection rate as detected by endoscopists were considered to be key measures for improvement. RESULTS The initial crude colonoscopy completion rate was 84.6%, with a range for individual endoscopists 80.4%-94%. Four endoscopists had a completion rate lower than 90%. The overall polyp detection rate was 34%, with a wide variation among endoscopists (range 14%-42%). Poor patient tolerance and differences in colonoscopist expertise were the main determinants of lack of completion and variation in polyp detection rate. Changes to sedation practice, greater access to endoscopy sessions for the endoscopists with the lowest performance rates, and other organizational arrangements, were implemented to improve quality performance. The crude completion rates improved consistently, up to 93.1%, over the study period. This trend was confirmed even when adjusted completion rates were calculated. All endoscopists reached a crude completion rate of 90% or more and a polyp detection rate of over 20%. The introduction of CQI did not significantly change the overall incidence of procedure-related complications. CONCLUSIONS The effectiveness of colonoscopy can be improved by implementing a CQI program in routine colonoscopy practice.

Abstract
BACKGROUND AND STUDY AIMS Endoscopic retrograde cholangiopancreatography (ERCP) is usually performed with the patient lying in the prone position, on the assumption that this position is optimal for cannulation of the papilla and for obtaining good-quality radiographic images. The supine position, however, may be more comfortable for the patient and may facilitate airway management, and this study aimed to compare the two positions in terms of procedure outcome, safety, and patient tolerance. PATIENTS AND METHODS Consecutive patients who were undergoing ERCP were randomized to start the procedure in either the prone position or the supine position. Patients under the age of 18 years, intubated patients, and those who had already undergone endoscopic sphincterotomy were excluded. The difficulty of cannulation was assessed using the Freeman score (1=one to five attempts; 2=six to 15 attempts; 3=more than 15 attempts; 4=failure of cannulation). Total procedure time, patient tolerance, willingness to undergo ERCP in the future, and procedure-related adverse cardiorespiratory events (oxygen desaturation, tachycardia, bradycardia) were also recorded. RESULTS A total of 34 patients were evaluated (21 men, 13 women; mean age 68, range 20-96), 17 patients in each group. Demographic and clinical features, and the indications for the procedure were similar for the two patient groups. The median Freeman score was significantly lower in the prone group compared with the supine group (1 vs. 3, P=0.0047, rank sum test). Biliary cannulation was achieved in all patients in the prone group, but was not achieved in five patients (29%) in the supine group (P=0.052). In four of these five patients, biliary cannulation was successfully achieved after turning the patient into the prone position. The percentage of patients unwilling to repeat the ERCP procedure in the future was higher in the supine group (29% vs. 6%, P=0.087); the mean tolerance score and mean total procedure time were similar in the two groups. Seven patients in the supine group experienced at least one adverse cardiorespiratory event, compared with only one patient in the prone group (41% vs. 6%, P=0.039). CONCLUSIONS ERCP performed with the patient in the supine position is technically more demanding for operators used to working with patients in the prone position and carries a greater risk of adverse cardiorespiratory events in nonintubated patients.

Abstract
OBJECTIVE To compare the efficacy and patient acceptance of an oral high dose of senna to conventional polyethylene glycol-electrolyte lavage solution (PEG-ES) in adults undergoing elective colonoscopy. METHODS Consecutive outpatients referred for elective colonoscopy were prospectively randomly assigned to receive, the day before the procedure, either 24 tablets of 12 mg senna, divided into two doses at 1 p.m. and 9 p.m. (senna group, n=191), or standard 4-L PEG-ES (PEG-ES group, n=92). The overall quality of colon cleansing (primary outcome measure) and cleansing in the right colon were evaluated using the Aronchick scoring scale (1=excellent to 4=inadequate) by the investigator/endoscopist who was blinded to the treatment assignment. Patient acceptance and the safety of the preparation were assessed by a nurse, using a structured questionnaire covering compliance with the dosing, overall tolerance of the preparation (1=none or mild discomfort to 4=severely distressing), and adverse events. RESULTS The quality of colon cleansing, overall tolerance of the preparation, and compliance were significantly better with senna; overall cleansing was excellent or good in 90.6% of patients in the senna group and in 79.7% in the PEG-ES group (p= 0.003). The percentage of procedures rescheduled because of insufficient colon cleansing was 7.3% in the PEG-ES group and 2.6% in the senna group (p=0.035). Multivariate logistic regression modeling showed the PEG-ES preparation as negative independent predictor of unsuccessful bowel cleansing. The incidence of adverse reactions was similar in the two groups; patients who received senna experienced significantly less nausea and vomiting, but more abdominal pain. CONCLUSIONS An oral high dose of senna is a valid alternative to standard PEG-ES for outpatient colonoscopy preparation.

Abstract
Rofecoxib is a selective cyclooxygenase-2 inhibitor that has been approved for the treatment of osteoarthritis and management of acute pain. Recent debate has emerged regarding the prothrombotic potential and the cardiovascular safety of this new drug, especially at doses greater than 25mg. We describe two extensively investigated cases of self-limited ischemic colitis in patients who were briefly treated with 50mg rofecoxib daily for acute pain. In both cases, the onset of symptoms correlated temporally with rofecoxib use and symptoms abated with drug discontinuation. There was no evidence of other possible causes of colon ischemia. A causal relationship between the start of rofecoxib treatment and the colon ischemia cannot be definitely established on the basis of the evidence, but the temporal relationship is striking and the pathophysiological rationale could be founded.

Abstract
BACKGROUND & AIMS It still is debated whether post-endoscopic retrograde cholangiopancreatography (ERCP) pancreatitis can be prevented by administering either somatostatin or gabexate mesylate. The aim of the study is to assess the efficacy of a 6.5-hour infusion of somatostatin or gabexate mesylate in preventing ERCP-related complications. METHODS In a double-blind multicenter trial, 1127 patients undergoing ERCP were randomly assigned to intravenous administration of somatostatin (750 microg; n = 351), gabexate mesylate (500 mg; n = 381), or placebo (saline; n = 395). The drug infusion started 30 minutes before and continued for 6 hours after endoscopy. Patients were evaluated clinically, and serum amylase levels were determined at 4, 24, and 48 hours after endoscopy. RESULTS No significant differences in incidences of pancreatitis, hyperamylasemia, or abdominal pain were observed among the placebo (4.8%, 32.6%, and 5.3%, respectively), somatostatin (6.3%, 26.8%, and 5.1%, respectively), and gabexate mesylate groups (5.8%, 31.5%, and 6.3%, respectively). Univariate analysis of patient characteristics and endoscopic maneuvers showed that a Freeman score >1 (P < 0.0001), >/=3 pancreatic injections (P < 0.00001), and precut sphincterotomy (P = 0.01) were significantly associated with post-ERCP pancreatitis. At multiple logistic regression analysis, >/=3 pancreatic injections (odds ratio [OR], 1.95; 95% confidence interval [CI], 1.45-2.63) and a Freeman score >1 (OR, 1.47; 95% CI, 1.11-1.94) retained their predictive power. CONCLUSIONS Long-term (6.5-hr) administration of either somatostatin or gabexate mesylate is ineffective for the prevention of post-ERCP pancreatitis. Pancreatic injury seems to be related to difficulty in common bile duct access.

Abstract
The practice of sedation and analgesia is under increasing scrutiny by numerous regulatory agencies, with the aim of making these procedures safer and reducing the incidence of cardiopulmonary complications during GI endoscopy. As we move toward more evidence-based medicine, new technologies will have to be assessed in a manner that demonstrates their efficacy and utility in clinical practice. Although there have been no controlled studies examining whether more intensive monitoring during endoscopy improves outcomes, extended monitoring with capnography seems to offer an advantage over conventional monitoring in that, by providing a real-time indication of any change in adequate ventilation before oxygen desaturation occurs, it can detect early phases of respiratory depression, which can allow a more precise and safer titration of medications. There is a close agreement among experts that capnography may reduce the risk of adverse outcomes during deep sedation; therefore, its use should be required for patients undergoing advanced endoscopic procedures with the potential for deep sedation. Extended monitoring with capnography should also be endorsed whenever propofol is considered as an alternative to standard sedation with a benzodiazepine or narcotic. Our understanding of the clinical application of techniques for monitoring of depth of sedation is in its infancy, and its full contribution to the practice of endoscopy has yet to be determined. Their potential role in improving sedation practice during endoscopy needs to be confirmed by controlled trials. If we consider the lack of proven efficacy of these emerging monitoring techniques in reducing the adverse outcomes associated with sedation and analgesia, the importance of appropriate monitoring cannot be overemphasized. However, it is vital for the endoscopist to be thoroughly familiar with the type of sedation chosen, to be able to recognize the various levels of sedation, and, above all, to rescue patients should they unintentionally progress to a deeper level of sedation than intended.

Abstract
BACKGROUND The aim of this study was to determine whether a single bolus of meperidine in addition to midazolam improves patient tolerance during colonoscopy. METHODS Consecutive patients undergoing outpatient colonoscopy were randomly assigned in double-blind fashion to receive a single rapid intravenous bolus of 5 mg of midazolam and placebo (Group A, n = 125) or 5 mg midazolam plus 50 mg meperidine (Group B, n = 128). Tolerance (4-point scale: 1 excellent, 4 unbearable), pain (4-point scale: 1 none, 4 severe) and willingness to undergo another colonoscopy were assessed 24 to 48 hours later in a telephone interview conducted by an independent observer blinded to the regimen of sedative medication. RESULTS Significantly more patients in Group A reported moderate or severe pain (28% vs. 9%; p < 0.001), poor or unbearable tolerance (18% vs. 6%; p < 0.01) and unwillingness to undergo colonoscopy again in the future (14% vs. 5%; p < 0.05). By multivariate analysis, randomization to the midazolam group and younger age were the only variables independently associated with the risk of reporting at least one of these outcomes. Recovery time, frequency of oxygen desaturation, and need for supplemental oxygen were not significantly different between the 2 groups. CONCLUSIONS The addition of a single bolus of meperidine to midazolam improves patient tolerance and lessens pain during colonoscopy without significantly increasing the frequency of side effects or prolonging recovery time.

Abstract
BACKGROUND ERCP is frequently complicated by pancreatitis. The aims of this study were to assess the efficacy of somatostatin and gabexate for prevention of post-ERCP pancreatitis in high-risk patients and to determine predisposing factors for post-ERCP pancreatitis. A meta-analysis was conducted of all published studies on the use of somatostatin or gabexate for prevention of post-ERCP pancreatitis. METHODS A double blind, multicenter, placebo-controlled trial was conducted in patients at high risk for post-ERCP pancreatitis. Patients were randomized to receive an intravenous infusion of somatostatin (750 mg), gabexate (500 mg), or placebo that was started 30 minutes before endoscopy and continued for 2 hours afterward. Patients were evaluated clinically and serum amylase levels determined at 4 and 24 hours after endoscopy. RESULTS No significant difference in the occurrence of pancreatitis, hyperamylasemia, or abdominal pain was observed among placebo-, gabexate-, and somatostatin-treated patients. A sphincterotomy longer than 2 cm (p = 0.0001), more than 3 pancreatic injections (p = 0.0001), and unsuccessful cannulation (p = 0.008) were predictive of post-ERCP pancreatitis. Hyperamylasemia was predicted by more than 3 pancreatic injections (p = 0.0001) and sphincterotomy (p = 0.02). The meta-analysis of trials of short-term infusion of gabexate or somatostatin did not show efficacy for either drug. CONCLUSIONS Short-term administration of gabexate or somatostatin in patients at high risk for pancreatitis is ineffective for prevention of ERCP-induced pancreatitis. Pancreatic injury is related to maneuvers used to obtain biliary access rather than to any patient characteristic or endoscopist experience.

Abstract
BACKGROUND The safety and tolerance of routine sedation and analgesia versus "on demand" sedation were compared in patients undergoing colonoscopy. METHODS Two hundred forty-nine outpatients were randomly assigned to one of two groups. Group A (n = 125) received midazolam, 0.07 mg/kg intravenously plus meperidine, 0.77 mg/kg intravenously immediately preceding the colonoscope insertion. Group B (n = 124) received the same medication upon request during the procedure. Tolerance was assessed 24 hours later by phone interview performed by a nurse blinded to the medication regimen administered. RESULTS Eighty-three patients (66%) in Group B required sedation during colonoscopy. Among men in Group B more than 60 years of age, only 23% required sedation. The proportion of patients reporting moderate or severe pain (34% vs. 12.1%, p < 0.001) and of those stating they would not be willing to undergo colonoscopy again in the future (22% vs. 9.7%, p < 0.005) was significantly higher in the "on demand" sedation group. By multivariate analysis the randomization group was the single variable independently associated with both such outcomes. The frequency of side effects was similar in the two groups. CONCLUSIONS Administration of sedative and analgesic drugs routinely before colonoscopy is superior to "on demand" sedation in terms of tolerance and is not associated with an increase in side effects.

Abstract
BACKGROUND Our aim was to compare the clinical efficacy of the Tannenbaum (TB) biliary prostheses, a recently designed Teflon stent without side holes, with the Cotton-Huibregtse (CH) polyethylene stent. METHODS Fifty-seven patients (26 men, mean age 75.5 years) with unresectable malignant tumors and distal biliary stenosis were included (38 pancreatic head cancer, 17 cholangiocarcinoma, 2 ampullary cancer). Patients were prospectively randomized to have a 10F, 7 cm long TB (29 patients) or CH (28 patients) stent inserted endoscopically. Four patients (2 TB and 2 CH) were excluded: 3 because of the failure of stent insertion and 1 because of a protocol violation. The patients were evaluated clinically and, if necessary, with biochemical tests every month until death or until they needed surgery for symptoms of gastric outlet obstruction. When occlusion or dislocation occurred, the stent was replaced with one of the same type. Cumulative stent patency and patient survival were estimated with the Kaplan-Meier life-table analysis and compared by log-rank chi-square test. RESULTS The two groups were comparable in mean age, gender, and diagnosis. The patients were followed for a mean of 145.5 days (range 24 to 613); by the end of the study 47 patients (81%) had died or developed symptoms of gastric outlet obstruction. Median survival was 88 days (range 24 to 613) in the TB group and 75.6 days (23 to 486) in the CH group. Stent exchange (occlusion 16, dislocation 3) was necessary for 5 patients in the TB group and 7 in the CH group. No statistical difference was found on comparing the mean duration of function of the first, second, and third stents (analysis of variance, p = 0.80). The median duration of stent function was 96 days (range 11 to 613) in the TB group and 75.5 days (range 23 to 323) in the CH group. No significant difference was found in either survival time (p = 0.48) or stent patency (p = 0.12). CONCLUSION This study found no significant advantage of the Tannenbaum prostheses over the standard polyethylene stent in the palliation for patients with distal malignant biliary stenosis with regard to survival or length of stent patency.

Abstract
BACKGROUND AND STUDY AIMS Little is known concerning the usefulness and feasibility of quality assurance programs in gastrointestinal departments. The aim of this study was to identify the indicators of quality in colonoscopy, to check their use in clinical practice, and to identify their threshold values. MATERIALS AND METHODS A prospective study was performed in four endoscopic units. In the first phase, a questionnaire was used to identify the indicators that were considered important and easy to record; in the second phase, the selected items were prospectively recorded. RESULTS Data from 603 colonoscopies were evaluated. The selected indicators were: rate of cecal intubation, rate of examinations with normal findings, rates of complications, appropriateness of indications, use of a washing machine for disinfection, duration of the disinfection procedure, rate of procedures repeated due to poor colon cleansing, rate of operative procedures, length of waiting time, rate of procedures performed for follow-up of known disease, experience of the operator, and rate of procedures performed with the patient under conscious sedation. A striking difference emerged between the technical standards at three centers, which were fairly good, and the standard at the fourth center, which was less satisfactory. The length of the waiting time was high in all centers, as well as the rate of examinations conducted with an inappropriate indication. The rate of procedures performed under conscious sedation varied widely between the centers. CONCLUSIONS The study of the indicators of quality of colonoscopy is feasible and easy to perform in clinical practice, and can be useful for quality assurance programs.

Abstract
We report a case of acute self-limiting ulcerative jejunitis of unknown aetiology in a 72-year-old female patient in which a subsequent diagnosis of microscopic polyangiitis and Sjogren's syndrome was made. All known causes of jejunal ulceration and inflammation were excluded. Previously reported cases of acute self-limiting jejunitis are reviewed and the possibility that acute jejunitis in this patient had been the first manifestation of systemic vasculitis is discussed.

Abstract
The clinico-pathologic entity of idiopathic granulomatous gastritis is a form of granulomatous gastritis, distinct from Crohn's disease, sarcoidosis, infections, foreign bodies, malignancy or vasculitis. The case of a 61-year-old female is described who was admitted on account of progressive weight loss, diffuse abdominal pains, post-prandial vomiting. Gastroscopy revealed a pyloric stenosis managed surgically. Pathological examination of the resected stomach showed numerous non-caseating granulomas in the lamina propria. No definite aetiological factor could be detected. A diagnosis of idiopathic granulomatous gastritis was made. She remains well 5 years later and has not developed regional enteritis, sarcoidosis, or any other generalized diseases.

Abstract
A new case of congenital short pancreas (partial agenesis or hypoplasia of the dorsal pancreas) is reported. The patient was a 61-year-old caucasian man, referred for two episodes of non-severe acute biliary pancreatitis. Clinical and laboratory findings and the presence of ultrasound biliary sludge in the gallbladder supported the biliary origin of pancreatitis. Computerized tomography revealed a slightly enlarged and hypodense head of the gland but could not identify any pancreatic tissue in the region of the body and tail. Endoscopic retrograde pancreatography showed a short pancreas with a duct system in communication both with the accessory and main papilla. Laparoscopic cholecystectomy was performed and no further episodes of abdominal pain occurred. Short pancreas is a rare congenital abnormality consisting in the parenchyma and ductal system restricted to the head with some residual dorsal tapering and arborizing ducts communicating with the minor papilla. This anomaly can be an incidental finding and its association with episodes of recurrent pancreatitis needs to be proven.

Abstract
BACKGROUND Dual therapy with omeprazole plus amoxycillin or with omeprazole plus clarithromycin has been proposed for eradication of Helicobacter pylori. The main problem is the great variability in the rate of eradication. METHODS A group of 287 consecutive patients with active peptic ulcers and H. pylori infections were admitted to a prospective, randomized, multicentre study, to be given omeprazole 20 mg b.d. plus either amoxycillin 1 g b.d. or clarithromycin 500 mg t.d.s. for 2 weeks. Cure was defined as the absence of H. pylori infection, 4-6 weeks after completing anti-microbial therapy, assessed by urease activity and histology of antral and body gastric biopsies. RESULTS The bacteria were eradicated in 68/143 patients (48%) treated with amoxycillin and omeprazole and 70/144 patients (49%) treated with clarithromycin and omeprazole (intention-to-treat analysis). The ulcers were healed in 118/127 patients (93%) treated with amoxycillin and in 115/123 (94%) of those treated with clarithromycin. Undesirable effects were rare with both treatments. CONCLUSIONS Combined treatment with omeprazole plus either amoxycillin or clarithromycin produced a high percentage of short-term healing of ulcers and was well tolerated, but is not useful as first-line anti-Helicobacter pylori treatment.

Abstract
Pseudoxanthoma elasticum (PXE) is a rare connective tissue disorder. The main clinical features of this condition are characteristic skin lesions, angioid streaks of the fundus oculi, and occlusive vascular disease. Gastric hemorrhage is a rare complication. A gastroscopic examination was performed on two patients with PXE who presented with upper gastrointestinal tract bleeding. The two patients had submucosal yellowish nodular lesions similar to the xanthoma-like skin lesions seen in the disease. We suggest that a diagnosis of PXE be considered for any patient with gastrointestinal hemorrhage, especially if routine clinical and endoscopic examination fail to reveal the cause, and if raised yellow plaque-like lesions are seen in the stomach by endoscopy.

Abstract
Two hundred patients affected by liver cirrhosis and oesophageal varices were studied in 9 Gastrointestinal Units in Lombardy (Northern Italy) in order to assess factors possibly related to variceal bleeding. Only patients without any previous episode of gastrointestinal bleeding were included in the prospective evaluation. For each patient demographic data, aetiology of cirrhosis, various clinical and biochemical parameters able to group patients into the three Child-Pugh Classes, endoscopic items for calculation of Beppu's and of NIEC prognostic scores were recorded on computerized cards. Patients were regularly interviewed every three months for one year and underwent an upper gastrointestinal endoscopy at enrollment, after six months and in case of bleeding. Within the twelve-month follow-up period, 29 out of the 200 patients (14%) bled and 52 out of 200 died (26%). In 16 of the 52 patients who died (59% of bleeding patients) death was directly related to gastrointestinal bleeding. Bleeding from oesophageal varices was endoscopically proven in 19/29 patients, in another 9 bleeding was classified as from unknown source and in one patient a bleeding gastric ulcer was diagnosed. Univariate analysis of all the recorded clinical, biochemical and endoscopic parameters, performed by Chi-square method and Fisher exact test showed that the presence of RWM (p < 0.001) was the only factor significantly associated to variceal bleeding within one year. Relationship between size of varices and bleeding was very close to the statistical significance but did not achieve it (p = 0.058).

Abstract
OBJECTIVE To evaluate if there was periodicity in the manifestations of gastrointestinal bleeding (hematemesis and melena). METHOD This is a multicenter prospective study carried out in the Endoscopy Units of eight hospitals. At the time of the emergency endoscopy, the following data were collected: age, sex, endoscopic diagnosis, solar hour of the first hematemesis (vomiting of bright red or tarry black material) and of the first melena (black or bloody soft stools), and any drugs taken during the week before the bleeding episode, regardless of the dose. RESULTS 806 patients were studied. Bleeding was from peptic ulcer in 405 patients (50%), from esophageal varices in 197 (24%), and from other sources in the remainder. Analysis using single cosinor statistics showed a nonrandom distribution in bleeding from peptic ulcer, whether presenting first with hematemesis (p = 0.02) or melena (p = 0.03). There were two peaks at 6:45 AM and 6:45 PM for hematemesis and at 7:25 AM and 7:25 PM for melena, representing a biphasic diurnal (ultradian) rhythm. CONCLUSIONS This study shows that bleeding due to peptic ulcer has a biphasic diurnal periodicity. This has potential importance for the pathogenesis of bleeding, for the management of gastrointestinal hemorrhage and the administration of drugs known to cause peptic ulcer bleeding.

Abstract
The evolution of gastric moderate and severe dysplasia was examined in a prospective multicenter study. One-hundred-and-nine of 141 patients with the endoscopic-bioptic diagnosis of moderate or severe dysplasia had an adequate follow-up and were included into the study. After revision of the initial slides by a gastrointestinal pathologist, 57 patients whose lesions did not meet the histological criteria for dysplasia were excluded, being reclassified as hyperplastic or metaplastic lesions (group 2). The 52 patients with confirmed moderate or severe dysplasia (group 1) were followed up for at least six months or underwent surgery for confirmed dysplasia or cancer. Thirty-two cancers were found in group 1 (33% in patients with moderate and 81% in patients with severe dysplasia). Among them, about half (n = 17) were early gastric cancers. Neither severe dysplasia nor cancer were found during the follow-up in group 2. Mean follow-up time was 13 months in group 1 and 16 months in group 2. Our results indicate that: 1) Confirmed moderate dysplasia shows a high risk of cancer development and requires strict bioptic follow-up; 2) Surgery is indicated in confirmed severe gastric dysplasia seen in the early detection of gastric cancer.

Abstract
UNLABELLED Hepatic hematomas, after liver biopsy, are collections of blood within the hepatic parenchyma and/or the hepatic capsula. The frequency of hematomas is reported to vary from 0% to 23% as a consequence of the patient selection and/or of the different diagnostic techniques (angiography, isotope techniques, ultrasound and CT scan). AIM To study prospectively, using the ultrasound scan, the incidence and the clinical significance of hematomas. METHODS 115 liver punctures were prospectively studied; before and 24 hours after the procedure the patients were submitted to liver US scan and CBC, transaminase and bilirubin were also checked. RESULTS The procedure was unsuccessful in one patient and none had more than one needle pass; five patients had two biopsies in different sessions. The 24 hour post-biopsy liver US scan did not show any hepatic hematomas. No patient had a significant drop in hemoglobin or in red blood cells. CONCLUSIONS Hepatic hematomas after liver biopsy are uncommon and of little clinical significance.
