Development and validation of a scoring system to predict response to obeticholic acid in primary biliary cholangitis. Clin Gastroenterol Hepatol 2024:S1542-3565(24)00482-8. [PMID: 38782175 DOI: 10.1016/j.cgh.2024.05.008] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/05/2024] [Revised: 05/02/2024] [Accepted: 05/07/2024] [Indexed: 05/25/2024]
Abstract
BACKGROUND & AIMS Obeticholic acid (OCA) is the only licensed second-line therapy for primary biliary cholangitis (PBC). With novel therapeutics in advanced development, clinical tools are needed to tailor the treatment algorithm. We aimed to derive and externally validate the OCA response score (ORS) for predicting the response probability of individuals with PBC to OCA. METHODS We used data from the Italian RECAPITULATE (N 441) and the IBER-PBC (N 244) OCA real-world prospective cohorts to derive/validate a score including widely available variables obtained either pre-treatment (ORS), or also after 6 months of treatment (ORS+). Multivariable Cox's regressions with backward selection were applied to obtain parsimonious predictive models. The predicted outcomes were biochemical response according to POISE (ALP/ULN<1.67 with a reduction of at least 15%, and normal bilirubin), or ALP/ULN<1.67, or NORMAL RANGE criteria (NR: normal ALP, ALT and bilirubin) up to 24 months. RESULTS Depending on the response criteria, ORS included age, pruritus, cirrhosis, ALP/ULN, ALT/ULN, GGT/ULN and bilirubin. ORS+ also included ALP/ULN and bilirubin after 6 months of OCA therapy. Internally validated c-statistics for ORS were of 0.75, 0.78 and 0.72 for POISE, ALP/ULN<1.67 and NR response, which raised to 0.83, 0.88, 0.81 with ORS+, respectively. The respective performances in validation were of 0.70, 0.72 and 0.71 for ORS, and 0.80, 0.84, 0.78 for ORS+. Results were consistent across groups with mild/severe disease. CONCLUSIONS We developed and externally validated a scoring system capable to predict OCA response according to different criteria. This tool will enhance a stratified second-line therapy model to streamline standard care and trial delivery in PBC.

Endoscopic Gastrointestinal Placement of Capsule Endoscopy to Investigate the Small Bowel: a Multicentric European Retrospective Series of 630 Procedures in Adult Patients. Gastrointest Endosc 2024:S0016-5107(24)00047-6. [PMID: 38272273 DOI: 10.1016/j.gie.2024.01.027] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/22/2023] [Revised: 11/29/2023] [Accepted: 01/15/2024] [Indexed: 01/27/2024]
Abstract
BACKGROUND AND AIMS Small bowel (SB) capsule endoscopy (CE) is a first line procedure for exploring the SB. Endoscopic GastroIntestinal PlacemenT (EGIPT) of SB CE is sometimes necessary. While the experience of EGIPT is large in pediatric populations, we aimed to describe the safety, efficacy and outcomes of EGIPT of SB CE in adult patients. METHODS The international CApsule endoscopy REsearch (iCARE) group set up a retrospective multicenter study. Patients over 18 year-old who underwent EGIPT of SB CE before May 2022 were included. Data were collected from medical records and capsule recordings. The primary endpoint was the technical success rate of the EGIPT procedures. RESULTS 630 patients were included (mean age 62.5 years old, 55.9% female) from 39,565 patients (1.6%) issued from 29 centers. EGIPT technical success was achieved in 610 procedures (96.8%). Anesthesia (moderate/deep sedation or general anesthesia) and centers with intermediate or high procedure loads were independent factors of technical success. Severe adverse events occurred in three (0.5%) patients. When technically successful, EGIPT was associated with a high SB CE completion rate (84.4%) and with a substantial diagnostic yield (61.1%). Completion rate was significantly higher when the capsule was delivered in the SB compared to when delivered in the stomach. CONCLUSION EGIPT of SB CE is highly feasible, safe and comes with high completion rate and diagnostic yield. When indicated, it should rather be performed under anesthesia and the capsule should be delivered in the duodenum rather than in the stomach, for better SB examination outcomes.

Abstract
The implementation of FIT programs reduces incidence and mortality from CRC in the screened subjects. The ultimate efficacy for CRC morbidity and mortality prevention in a FIT program depends on the colonoscopy in FIT+ subjects that has the task of detecting and removing these advanced lesions. Recently, there has been growing evidence on factors that influence the quality of colonoscopy specifically withing organized FIT programs, prompting to dedicated interventions in order to maximize the benefit/harm ratio of post-FIT colonoscopy. This document focuses on the diagnostic phase of colonoscopy, providing indications on how to standardise colonoscopy in FIT+ subjects, regarding timing of examination, management of antithrombotic therapy, bowel preparation, competence and sedation.

Abstract
Background and Aim: Double-balloon enteroscopy (DBE) is a well-established procedure for direct visualisation of the entire small bowel mucosa, and, in contrast with other imaging techniques, allows to perform biopsies and therapeutic interventions. The aim of this study was to evaluate the indications, diagnostic yield, therapeutic yield, and complications of DBE in a cohort of consecutive patients according to patients’ age. Methods: We conducted a retrospective study of consecutive patients who underwent DBE in our endoscopy unit between January 2006 and December 2021. Results: A total of 387 consecutive patients who underwent 460 DBE procedures were included. Mean age of the patients was 63 years. The overall diagnostic yield was 67.6%; vascular lesions were the predominant endoscopic findings (31.5%), followed by polyps or neoplastic masses (17.6%). Older patients (≥65 years) showed statistically higher rates of clinically relevant findings than adult patients (18–65 years) (p = 0.001). Crohn’s disease and polyps or neoplastic masses were more frequent in the younger group (p = 0.009 and p = 0.066, respectively), while vascular lesions and non-specific inflammation were the most common findings in the older group (p < 0.001 and p < 0.001, respectively). The therapeutic intervention rate was 31.7%. Rates of endoscopic treatment were significantly higher in the older group (p < 0.001). Total complications occurred in five procedures (1.1%). Conclusion: In clinical practice, DBE is an efficient diagnostic and therapeutic tool with a high safety profile, particularly in the elderly population.

Abstract
BACKGROUND AND AIM Among the Endoscopic retrograde cholangiopancreatography (ERCP) adverse events, an increasingly arising problem is the transmission of Multi Drug Resistant (MDR) Bacteria through duodenoscopes. The aim of this survey was to evaluate the current clinical practice of management of ERCP associated infections in Emilia-Romagna, Italy. METHODS An online survey was developed including 12 questions on management of ERCP associated infections risk. The survey was proposed to all 12 endoscopy centers in Emilia Romagna that perform at least > 200 ERCPs per year. RESULTS 11 centers completed the survey (92%). Among all risk factors of ERCP infections, hospitalization in intensive care units, immunosuppressant therapies, and previous MDR infections have achieved a 80 % minimum of concurrence by our respondents. The majority of them did not have a formalized document in their hospital describing categories and risk factors helpful in the detection of patients undergoing ERCP with an high-level infective risk (9/11, 82%). Most centers (8/11, 72%) do not perform screening in patients at risk of ERCP infections. Post procedural monitoring is performed by 6 of 11 centers (55%). CONCLUSION Our survey showed that, at least at regional level, there is a lack of procedures and protocols related to the management of patients at risk of ERCP infections.

Small-bowel capsule endoscopy in patients with Meckel's diverticulum: clinical features, diagnostic workup, and findings. A European multicenter I-CARE study. Gastrointest Endosc 2022; 97:917-926.e3. [PMID: 36572128 DOI: 10.1016/j.gie.2022.12.014] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/23/2022] [Revised: 11/29/2022] [Accepted: 12/14/2022] [Indexed: 02/08/2023]
Abstract
BACKGROUND AND AIMS Meckel's diverticulum (MD) may remain silent or be associated with adverse events such as GI bleeding. The main aim of this study was to evaluate indicative small-bowel capsule endoscopy (SBCE) findings, and the secondary aim was to describe clinical presentation in patients with MD. METHODS This retrospective European multicenter study included patients with MD undergoing SBCE from 2001 until July 2021. RESULTS Sixty-nine patients with a confirmed MD were included. Median age was 32 years with a male-to-female ratio of approximately 3:1. GI bleeding or iron-deficiency anemia was present in nearly all patients. Mean hemoglobin was 7.63 ± 1.8 g/dL with a transfusion requirement of 52.2%. Typical capsule endoscopy (CE) findings were double lumen (n = 49 [71%]), visible entrance into the MD (n = 49 [71%]), mucosal webs (n = 30 [43.5%]), and bulges (n = 19 [27.5%]). Two or more of these findings were seen in 48 patients (69.6%). Ulcers were detected in 52.2% of patients (n = 36). In 63.8% of patients (n = 44), a combination of double lumen and visible entrance into the MD was evident, additionally revealing ulcers in 39.1% (n = 27). Mean percent SB transit time for the first indicative image of MD was 57% of the total SB transit time. CONCLUSIONS Diagnosis of MD is rare and sometimes challenging, and a preoperative criterion standard does not exist. In SBCE, the most frequent findings were double-lumen sign and visible diverticular entrance, sometimes together with ulcers.

Abstract
BACKGROUND Few studies focused on minor adverse events which may develop after colonoscopy. AIMS To investigate the incidence and factors associated to post-colonoscopy symptoms. METHODS This is a prospective study conducted in 10 Italian hospitals. The main outcome was a cumulative score combining 10 gastrointestinal (GI) symptoms occurring the week following colonoscopy. The analyses were conducted via multivariate logistic regression. RESULTS Of 793 subjects included in the analysis, 361 (45.5%) complained the new onset of at least one GI symptom after the exam; one symptom was reported by 202 (25.5%), two or more symptoms by 159 (20.1%). Newly developed symptoms more frequently reported were epigastric/abdominal bloating (32.2%), pain (17.3%), and dyspeptic symptoms (17.9%). Symptoms were associated with female sex (odds ratio [OR]=2.54), increasing number of symptoms developed during bowel preparation intake (OR=1.35) and somatic symptoms (OR=1.27). An inverse association was observed with better mood (OR=0.74). A high-risk profile was identified, represented by women with bad mood and somatic symptoms (OR=8.81). CONCLUSION About half of the patients develop de novo GI symptoms following colonoscopy. Improving bowel preparation tolerability may reduce the incidence of post-colonoscopy symptoms, especially in more vulnerable patients.

Abstract
BACKGROUND: Reading capsule endoscopy (CE) is time-consuming. The Express View (EV) (IntroMedic, Seoul, Korea) software was designed to shorten CE video reading. Our primary aim was to evaluate the diagnostic accuracy of EV in detecting significant small-bowel (SB) lesions. We also compared the reading times with EV mode and standard reading (SR). METHODS: 126 patients with suspected SB bleeding and/or suspected neoplasia were prospectively enrolled and underwent SB CE (MiroCam®1200, IntroMedic, Seoul, Korea). CE evaluation was performed in standard and EV mode. In case of discrepancies between SR and EV readings, a consensus was reached after reviewing the video segments and the findings were re-classified. RESULTS: The completion rate of SB CE in our cohort was 86.5% and no retention occurred. The per-patient analysis of sensitivity, specificity, positive predictive value, negative predictive value, and diagnostic accuracy of EV compared to SR were 86%, 86%, 90%, 81%, and 86%, respectively, before consensus. After consensus, they increased to 97%, 100%, 100%, 96%, and 98%, respectively. The median reading time with SR and EV was 71 min (range 26−340) and 13 min (range 3−85), respectively (p < 0.001). CONCLUSIONS: The new-generation EV shows high diagnostic accuracy and significantly reduces CE reading times.

Abstract
Over the last few years, capsule endoscopy has been established as a fundamental device in the practicing gastroenterologist’s toolbox. Its utilization in diagnostic algorithms for suspected small bowel bleeding, Crohn’s disease, and small bowel tumors has been approved by several guidelines. The advent of double-balloon enteroscopy has significantly increased the therapeutic possibilities and release of multiple devices (single-balloon enteroscopy and spiral enteroscopy) aimed at improving the performance of small bowel enteroscopy. Recently, some important innovations have appeared in the small bowel endoscopy scene, providing further improvement to its evolution. Artificial intelligence in capsule endoscopy should increase diagnostic accuracy and reading efficiency, and the introduction of motorized spiral enteroscopy into clinical practice could also improve the therapeutic yield. This review focuses on the most recent studies on artificial-intelligence-assisted capsule endoscopy and motorized spiral enteroscopy.

Abstract
(1) Background: Villous atrophy is an indication for small bowel capsule endoscopy (SBCE). However, SBCE findings are not described uniformly and atrophic features are sometimes not recognized; (2) Methods: The Delphi technique was employed to reach agreement among a panel of SBCE experts. The nomenclature and definitions of SBCE lesions suggesting the presence of atrophy were decided in a core group of 10 experts. Four images of each lesion were chosen from a large SBCE database and agreement on the correspondence between the picture and the definition was evaluated using the Delphi method in a broadened group of 36 experts. All images corresponded to histologically proven mucosal atrophy; (3) Results: Four types of atrophic lesions were identified: mosaicism, scalloping, folds reduction, and granular mucosa. The core group succeeded in reaching agreement on the nomenclature and the descriptions of these items. Consensus in matching the agreed definitions for the proposed set of images was met for mosaicism (88.9% in the first round), scalloping (97.2% in the first round), and folds reduction (94.4% in the first round), but granular mucosa failed to achieve consensus (75.0% in the third round); (4) Conclusions: Consensus among SBCE experts on atrophic lesions was met for the first time. Mosaicism, scalloping, and folds reduction are the most reliable signs, while the description of granular mucosa remains uncertain.

Abstract
BACKGROUND & AIM Although acute lower GI bleeding (LGIB) represents a significant healthcare burden, prospective real-life data on management and outcomes are scanty. Present multicentre, prospective cohort study was aimed at evaluating mortality and associated risk factors and at describing patient management. METHODS Adult outpatients acutely admitted for or developing LGIB during hospitalization were consecutively enrolled in 15 high-volume referral centers. Demographics, comorbidities, medications, interventions and outcomes were recorded. RESULTS Overall 1,198 patients (1060 new admissions;138 inpatients) were included. Most patients were elderly (mean-age 74±15 years), 31% had a Charlson-Comorbidity-Index ≥3, 58% were on antithrombotic therapy. In-hospital mortality (primary outcome) was 3.4% (95%CI 2.5-4.6). At logistic regression analysis, independent predictors of mortality were increasing age, comorbidity, inpatient status, hemodynamic instability at presentation, and ICU-admission. Colonoscopy had a 78.8% diagnostic yield, with significantly higher hemostasis rate when performed within 24-hours than later (21.3% vs.10.8%, p = 0.027). Endoscopic hemostasis was associated with neither in-hospital mortality nor rebleeding. A definite or presumptive source of bleeding was disclosed in 90.4% of investigated patients. CONCLUSION Mortality in LGIB patients is mainly related to age and comorbidities. Although early colonoscopy has a relevant diagnostic yield and is associated with higher therapeutic intervention rate, endoscopic hemostasis is not associated with improved clinical outcomes [ClinicalTrial.gov number: NCT04364412].

Abstract
BACKGROUND Diverticular bleeding is the main cause of lower gastrointestinal bleeding in both Eastern and Western countries. Several risk factors have been identified, such as comorbidities and concomitant medications. In Eastern population, the prevalence of right-side diverticulosis is higher than in Western one, and some Authors identified bilateral diverticulosis as a risk factor for bleeding. AIMS To identify risk factors for diverticular bleeding in patients admitted for diverticular disease (DD). METHODS All patients admitted for DD from January 2017 to December 2018 were retrieved from the hospital Information System. For each patient, age, gender, clinical presentation and concomitant medication were recorded. All patient underwent imaging assessment (computed tomography, ultrasound or MRI) and colonoscopy during hospitalization or within one month. RESULTS Among 1248 patients discharged with a diagnosis of DD during the study period, 293 (52.2% male, median age 75 years) were finally analyzed; of them, 105 (35.8%) for diverticular bleeding. On multivariate analysis, male gender (OR 4.27), age (OR 1.12), anti-thrombotic medications (OR 2.60) and right-sided DD (OR 5.70) were independently correlated to diverticular bleeding. CONCLUSION Our study provides evidence that, together with age, male gender and concomitant anti-thrombotic treatment, right-sided DD represents an independent risk factor for bleeding.

[PMID: 33250131 DOI: 10.1016/j.dld.2020.10.006] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/05/2020] [Revised: 09/28/2020] [Accepted: 10/01/2020] [Indexed: 12/11/2022]
Abstract
BACKGROUND Inpatients are at risk for inadequate colon cleansing. Experts recommend 4L-polyethylene-glycol (PEG) solution. A higher colon cleansing adequacy rate for a hyperosmolar 1L-PEG plus ascorbate prep has been recently reported. AIMS We aimed to determine whether 1L-PEG outperforms 4L-PEG among inpatients. METHODS post-hoc analysis of a large Italian multicenter prospective observational study among inpatients (QIPS study). We performed a propensity score matching between 1L-PEG and 4L-PEG group. The primary outcome was the rate of adequate colon cleansing as assessed by unblinded endoscopists through Boston scale. Secondary outcome was the safety profile. RESULTS Among 1,004 patients undergoing colonoscopy, 724 (72%) were prescribed 4L-PEG and 280 (28%) 1L-PEG. The overall adequate colon cleansing rate was 69.2% (n = 695). We matched 274 pairs of patients with similar distribution of confounders. The rate of patients with adequate colon cleansing was higher in 1L-PEG than in 4L-PEG group (84.3% vs. 77.4%, p = 0.039). No different shift in serum concentration of electrolytes (namely Na+, K+, Ca2+), creatinine and hematocrit were observed for both preparations. CONCLUSION We found a higher rate of adequate colon cleansing for colonoscopy with the 1L-PEG bowel prep vs. 4L-PEG, with apparent similar safety profile, among inpatients. A confirmatory randomized trial is needed. (ClinicalTrials.gov no: NCT04310332).

Abstract
BACKGROUND Patients with prior colon cancer have increased risk of metachronous colorectal neoplasms; therefore, endoscopic surveillance is indicated. Current recommendations are not risk-stratified. We investigated predictive factors for colorectal neoplasms to build a model to spare colonoscopies for low-risk patients. METHODS This was a multicenter, retrospective study including patients who underwent surgery for colon cancer in 2001 - 2008 (derivation cohort) and 2009 - 2013 (validation cohort). A predictive model for neoplasm occurrence at second surveillance colonoscopy was developed and validated. RESULTS 421 and 203 patients were included in derivation and validation cohort, respectively. At second surveillance colonoscopy, 112 (26.6 %) and 55 (27.1 %) patients had metachronous neoplasms in derivation and validation groups; three cancers were detected in the latter. History of left-sided colon cancer (OR 1.64, 95 %CI 1.02 - 2.64), ≥ 1 advanced adenoma at index colonoscopy (OR 1.90, 95 %CI 1.05 - 3.43), and ≥ 1 adenoma at first surveillance colonoscopy (OR 2.06, 95 %CI 1.29 - 3.27) were independently predictive of metachronous colorectal neoplasms at second surveillance colonoscopy. For patients without such risk factors, diagnostic accuracy parameters were: 89.3 % (95 %CI 82.0 %-94.3 %) and 78.2 % (95 %CI 65.0 %-88.2 %) sensitivity, and 28.5 % (95 %CI 23.5 %-33.9 %) and 33.8 % (95 %CI 26.2 %-42.0 %) specificity in derivation and validation group, respectively. No cancer would be missed. CONCLUSIONS Patients with prior left-sided colon cancer or ≥ 1 advanced adenoma at index colonoscopy or ≥ 1 adenoma at first surveillance colonoscopy had a significantly higher risk of neoplasms at second surveillance colonoscopy; patients without such factors had much lower risk and could safely skip the second surveillance colonoscopy. A prospective, multicenter validation study is needed.

Abstract
Background and aim: Response to ursodeoxycholic acid (UDCA) is crucial for the prediction of primary biliary cholangitis (PBC) prognosis, and different response criteria were validated and proposed by reference centers for PBC. To date, rates of non-response to UDCA from real-world series are lacking.Methods: Hepatology/Gastroenterology centers belonging to 'Club Epatologi Ospedalieri' (CLEO) and 'Associazione Italiana Gastroenterologi Ospedalieri' (AIGO) were invited to participate in the study, and asked to extract all patients followed for PBC, without any selection or exclusion, and fill in the database provided.Results: Thirty-four centers were enrolled throughout Italy, for a total of 713 patients. None of these centers, except one, had a hepatology outpatient clinic devoted to the care of patients with autoimmune liver diseases. After excluding 79 cases of PBC/autoimmune hepatitis overlaps, 634 patients were analyzed: mean age, 64.4 ± 12.0 years; 91.2% females; F/M 10.3/1. For patients with at least 1 year of UDCA treatment (583), rates of non-response to UDCA were evaluated according to the Paris-I/-II, Toronto and GLOBE criteria, and compared with those in the original cohorts: 27% vs 39% in Paris-I cohort; 39.6% vs 52% in Paris-II; 20.1% vs 43.5% in Toronto; 15.7% vs 30% in GLOBE (age-specific cutoffs). Mean alkaline phosphatase levels on UDCA treatment, and the age-adjusted prevalence of F3/F4 fibrosis, appeared lower in this PBC population than in reference cohorts.Conclusions: A mean ∼15% better response to UDCA is observed in a real-world PBC population, probably due to migration of some of most severe/advanced cases to PBC referral centers.

Abstract
The lumen-apposing metal stent (LAMS) is one of the revolutionary devices recently developed for gastrointestinal endoscopy. This device has a saddle-shaped design and large lumen. It was originally designed for drainage of transmural pancreatic fluid collection and in the last few years it has been used extensively for that indication. More recently, other in- and off-label indications have been proposed. Several types of LAMS are available, with or without an electrocautery-enhanced delivery system. In the current review we discuss the state of the art with regard to LAMS and their indications, usage, and outcomes.

Abstract
Background: The aim of our study was to test the long-term efficacy of Endo-SPONGE® therapy in a group of patients treated in our center with vacuum-assisted therapy because of anastomotic leakages after colorectal surgery. Methods: Eleven patients [male: 6; mean age: 71 (range: 44-82) years] who had anastomotic leakage treated with Endo-SPONGE® placement were included in the study. Patient records were examined retrospectively. All patients with documented anastomotic leakage on abdominal computed tomography following an anterior resection of the rectum for rectal cancer underwent sigmoidoscopy to determine the extent of the anastomotic defect and the size of the presacral abscess. Results: Ten of the 11 patients (90.9%) showed closure of the anastomotic leakage after a mean of 16 sponge changes. During follow up [mean: 29 (range: 6-64) months], we observed two cases of anastomotic stricture. Treatment failure was observed in one patient who presented an increased size of dehiscence after 23 sessions of endoscopic treatment, despite an initial good response. Conclusions: Our study substantially confirms previous conclusions and reaffirms that Endo-SPONGE® treatment for colorectal anastomotic leakages, performed in suitable patients, represents a successful and safe approach. The reduction in wound closure time, mild-to-moderate discomfort and possibly shorter hospitalization suggest that Endo-SPONGE® treatment can be a prominent therapeutic regimen with adequate patient acceptance.

Abstract
BACKGROUND AND STUDY AIM The study compared the efficacy of bowel cleansing using a low-volume mixed preparation (15 mg bisacodyl plus 2 L polyethylene glycol [PEG] solution) versus a standard high-volume preparation (4 L PEG) in patients with previous colorectal resection. PATIENTS AND METHODS A total of 120 patients with prior colorectal resection for cancer undergoing surveillance colonoscopy were randomized to receive either a split-dose low-volume (n = 60) or high-volume (n = 60) preparation for bowel cleansing. The quality of bowel preparation, rated according to a modified Ottawa Bowel Preparation scale (mOBPS), represented the primary outcome measure. Tolerability, safety, and lesion detection rates were secondary outcomes. RESULTS No significant difference was observed between the low-volume and high-volume preparations in achievement of adequate cleansing (i. e. mOBPS ≤ 4; low-volume vs. high-volume group, 85.0 % vs. 81.7 %, P = 0.624). The low-volume preparation showed a higher success rate for cleansing of the right colon (P = 0.025); better tolerability in terms of intake of the whole amount of the preparation (P < 0.001) was also observed. According to the logistic regression analysis, the only predictors of unsuccessful cleansing were previous left colectomy (P = 0.012) and a longer elapsed time since the intervention (P = 0.034). Lesion detection rates were comparable between the groups. No serious adverse events were reported. CONCLUSION A low-volume preparation is not inferior to a high-volume preparation for adequate bowel cleansing in patients with prior colorectal resection for cancer. If larger, multicenter, prospective studies confirm our findings, a low-volume preparation will represent a more tolerable option for such patients.

Abstract
BACKGROUND Patients with history of colonic resection for cancer have an increased risk of the development of metachronous malignant and premalignant lesions. Scanty data are reported on detection rates of premalignant lesions during colonoscopy surveillance in this setting. OBJECTIVE To assess the risk of metachronous precancerous lesions developing in patients with previous colonic surgery for cancer according to the resection type. DESIGN Retrospective study. SETTING Two academic centers in Italy. PATIENTS A total of 441 patients; 256 with previous left-sided colectomy (LCR) (LCR group) and 185 with previous right-sided colectomy (RCR) (RCR group). INTERVENTIONS Second surveillance colonoscopy. MAIN OUTCOME MEASUREMENTS Polyp and adenoma detection rates. RESULTS At least 1 adenoma was diagnosed in 76 of 256 patients (30% adenoma detection rate) and in 35 of 185 patients (19% adenoma detection rate) in the LCR and RCR groups, respectively (P=.014), yielding an odds ratio of 1.83 (95% confidence interval, 1.16-2.89). Corresponding figures for the polyp detection rate were 39% and 25%, respectively (P=.002; odds ratio 1.97; 95% confidence interval, 1.30-3.00). LIMITATIONS Retrospective study with colonoscopy baseline information missing. CONCLUSIONS Patients who have undergone LCR are at higher risk of the development of adenomas than those who have undergone RCR. If this result is confirmed by large prospective studies, surveillance programs could be targeted according to the type of colonic resection, with longer intervals for patients with previous RCR compared with LCR.

Abstract
Pelvic radiation disease is one of the major complication after radiotherapy for pelvic cancers. The most commonly reported symptom is rectal bleeding which affects patients' quality of life. Therapeutic strategies for rectal bleeding are generally ignored and include medical, endoscopic, and hyperbaric oxygen treatments. Most cases of radiation-induced bleeding are mild and self-limiting, and treatment is normally not indicated. In cases of clinically significant bleeding (i.e. anaemia), medical therapies, including stool softeners, sucralfate enemas, and metronidazole, should be considered as first-line treatment options. In cases of failure, endoscopic therapy, mainly represented by argon plasma coagulation and hyperbaric oxygen treatments, are valid and complementary second-line treatment strategies. Although current treatment options are not always supported by high-quality studies, patients should be reassured that treatment options exist and success is achieved in most cases if the patient is referred to a dedicated centre.

Abstract
BACKGROUND Capsule endoscopy is an established tool for the evaluation of obscure gastrointestinal bleeding but published literature is mostly limited to PillCam SB (Given Imaging, Israel). AIMS The aims of this study were to determine the findings, the diagnostic yield and the rebleeding rate in a series of patients with overt or occult obscure gastrointestinal bleeding studied with MiroCam(Intromedic, Seoul, Korea) capsule endoscopy. METHODS Data of 118 patients who underwent capsule endoscopy for overt or occult obscure gastrointestinal bleeding were prospectively collected between March 2009 and March 2011. RESULTS Evaluation of the entire small bowel (completion rate) was achieved in 96% of cases. Relevant lesions occurred in 58% of patients. Angiodysplasias was the most common finding. Six patients (9% of the positive findings) had a non-small-bowel lesion detected by capsule. The yield of capsule endoscopy in the overt group was greater than in the occult group but without achieving a significant difference (61% vs. 54%, p>0.05). Rebleeding rate was lower in patients with a negative examination (6%) than in patients with a positive one (17%) (p=0.03). Capsule retention was registered in 3 of 118 patients (2.5%). CONCLUSIONS MiroCam capsule endoscopy is a safe and effective tool for exploring small bowel with a high completion rate.

Abstract
Gastric antral vascular ectasia (GAVE) is an uncommon but often severe cause of upper gastrointestinal (GI) bleeding, responsible of about 4% of non-variceal upper GI haemorrhage. The diagnosis is mainly based on endoscopic pattern and, for uncertain cases, on histology. GAVE is characterized by a pathognomonic endoscopic pattern, mainly represented by red spots either organized in stripes radially departing from pylorus, defined as watermelon stomach, or arranged in a diffused-way, the so called honeycomb stomach. The histological pattern, although not pathognomonic, is characterized by four alterations: vascular ectasia of mucosal capillaries, focal thrombosis, spindle cell proliferation and fibrohyalinosis, which consist of homogeneous substance around the ectatic capillaries of the lamina propria. The main differential diagnosis is with Portal Hypertensive Gastropathy, that can frequently co-exists, since about 30% of patients with GAVE co-present a liver cirrhosis. Autoimmune disorders, mainly represented by Reynaud’s phenomenon and sclerodactyly, are co-present in about 60% of patients with GAVE; other autoimmune and connective tissue disorders are occasionally reported such as Sjogren’s syndrome, systemic lupus erythematosus, primary biliary cirrhosis and systemic sclerosis. In the remaining cases, GAVE syndrome has been described in patients with chronic renal failure, bone marrow transplantation and cardiac diseases. The pathogenesis of GAVE is still obscure and many hypotheses have been proposed such as mechanical stress, humoural and autoimmune factors and hemodynamic alterations. In the last two decades, many therapeutic options have been proposed including surgical, endoscopic and medical choices. Medical therapy has not clearly shown satisfactory results and surgery should only be considered for refractory severe cases, since this approach has significant mortality and morbidity risks, especially in the setting of portal hypertension and liver cirrhosis. Endoscopic therapy, particularly treatment with Argon Plasma Coagulation, has shown to be as effective and also safer than surgery, and should be considered the first-line treatment for patients with GAVE-related bleeding.

Abstract
BACKGROUND The Physiological and Operative Severity Score for the enUmeration of Mortality and morbidity model, and its Portsmouth and colorectal modifications are used to predict postoperative mortality and morbidity after colorectal surgery. AIMS To compare stent placement as a bridge to surgery vs. emergency surgical resection in patients with acute left-sided colorectal cancer obstruction using P-POSSUM and CR-POSSUM. METHODS From January 2008 to December 2009, the physiological and operative scores, morbidity and mortality predicted by the P-POSSUM and CR-POSSUM scores were collected in all consecutive patients with LCCO who underwent surgical resection directly (Group A) or after stent placement (Group B). RESULTS Eighty-six patients were enrolled (Group A-41 and Group B-45). The observed 30-day mortality rate was 9.8% (4/41) in Group A and 2.4% (1/45) in Group B. The 30-day morbidity rate was 61% (25/41) in Group A and 29% (13/45) in Group B. The mean values of P-POSSUM morbidity (A=70.5% vs. B=34.3%; p=0.001), P-POSSUM mortality (A=13.6% vs. B=2.4%; p=0.001) and CR-POSSUM mortality (A=15.1% vs. B=4.9%; p=0.001) were significantly lower in the Group B patients than in the Group A patients. CONCLUSIONS Bridge to surgery strategy reduces the surgical risks in LCCO, and P-POSSUM and CR-POSSUM scores represent a good tool for comparing the two strategies.

Abstract
BACKGROUND In short-segment Barrett's oesophagus (SSBO) heartburn may be absent and oesophageal acid exposure time (OAET) assessed with pH-only monitoring may be normal. By detecting reflux episodes independently of their acidity, multichannel intraluminal impedance-pH (MII-pH) monitoring allows a comprehensive characterization of reflux events, either off or on proton pump inhibitor (PPI) therapy. AIM To assess reflux parameters by MII-pH monitoring in newly diagnosed SSBO, at baseline and as modified with PPI therapy. METHODS Short-segment Barrett's oesophagus was defined by oesophageal intestinal metaplasia up to 3 cm in length. 24-h MII-pH monitoring was performed before and during PPI therapy. RESULTS Fifty patients were studied prospectively. Normal OAET was found at baseline in 15 patients (30%), 8 and 2 of whom with a higher than normal number of acid and weakly acidic refluxes, respectively. Overall, abnormal reflux parameters were detected by MII-pH monitoring in 90% of patients. Reflux events were prevalent in the upright period. On PPI therapy, acid refluxes decreased and a correspondent increase in weakly acidic refluxes was observed (median from 48.5 to 9 and from 16 to 57.5, respectively) (P < 0.001). CONCLUSIONS Acid refluxes, mainly in the upright period, characterize SSBO. PPI therapy transforms acid refluxes into weakly acidic refluxes.

Abstract
BACKGROUND Overweight and obesity lead to serious health consequences, so that many strategies were recommended for preventing or curing this emerging problem. Treatments are various: diet, physical activity, psychotherapy, drugs, and bariatric surgery. Moreover, during these years, the use of intragastric balloon (BIB) to treat obesity increased rapidly, aimed to (1) reduce bariatric surgical risks; (2) reduce general surgical risks; (3) lead to a significant reduction in the prevalence of cardiovascular diseases, diabetes, musculoskeletal disorders and some cancers. Recently, a new device inflated with air to reduce weight has been developed since 2004 (Heliosphere BAG). METHODS Between March 2006 and September 2006, in our unit, intragastric air-filled balloon insertion was performed under general anesthesia and endoscopic control. The balloons were removed after 6 months. We evaluated efficacy, tolerance, and safety of this technique. Seventeen patients (eight men, nine women), with a mean age of 43 +/- 10 years (range 18-65), mean basal BMI of 46 +/- 8 (range 35-58) were included, after providing informed consent. Weight and BMI loss were evaluated in all patients. RESULTS BMI decreased 4 +/- 3 (range +0.33/-11), weight loss was 11 +/- 9 kg (range +1/-29.5; 8.5%). 14/17 patients maintain a BMI > 35 at the time of balloon removal. The difference between initial weight and BMI was statistically significant (p = 0.02 for weight and p < 0.01 for BMI, T Student test). Tolerance was very good, limited only to some dyspeptic symptoms during the first 3 days after insertion. One asymptomatic gastric ulcer was seen at the removal of balloon. Only one severe adverse effect was registered at the time of insertion (acute coronary syndrome in patient with chronic coronary disease). No serious technical problems were noted at balloon insertion. Balloon removal was more difficult and successful in 15/17 cases (one distal migration and one patient led to surgery because of balloon fragmentation). CONCLUSION Intragastric air-filled balloon showed a good profile of efficacy and tolerance. Weight loss appeared to be equivalent to other type of balloons. On the other hand, technical problems (especially at the time of removal) probably linked to the device's material, set a low safety profile.
