RESUMEN
BACKGROUND: First-line over-the-scope (OTS) clip treatment has shown higher efficacy than standard endoscopic therapy in acute nonvariceal upper gastrointestinal bleeding (NVUGIB) from different causes. We compared OTS clips with through-the-scope (TTS) clips as first-line mechanical treatment in the specific setting of peptic ulcer bleeding. METHODS: We conducted an international, multicenter randomized controlled trial on consecutive patients with suspected NVUGIB. Patients with Forrest Ia-IIb gastroduodenal peptic ulcer were randomized 1:1 to OTS clip or TTS clip treatment. The primary outcome was the rate of 30-day rebleeding after successful initial hemostasis. Secondary outcomes included the rates of successful initial hemostasis and overall clinical success, defined as the composite of successful initial hemostasis and no evidence of 30-day rebleeding. RESULTS: 251 patients were screened and 112 patients were randomized to OTS (n = 61) or TTS (n = 51) clip treatment. The 30-day rebleeding rates were 1.6% (1/61) and 3.9% (2/51) in patients treated with OTS clips and TTS clips, respectively (Kaplan-Meier log-rank, P = 0.46). Successful initial hemostasis rates were 98.4% (60/61) in the OTS clip group and 78.4% (40/51) in the TTS clip group (P = 0.001). Overall clinical success rates were 96.7% (59/61) with OTS clips and 74.5% (38/51) with TTS clips (P = 0.001). CONCLUSIONS: Low rates of 30-day rebleeding were observed after first-line endoscopic treatment of acute peptic ulcer bleeding with either OTS or TTS clips. However, OTS clips showed higher efficacy than TTS clips in achieving successful initial hemostasis and overall clinical success.

RESUMEN
INTRODUCTION: Preoperative gastric cancer (GC) staging is the most reliable prognostic factor that affects therapeutic strategies. Contrast-enhanced computed tomography (CECT) and radial endoscopic ultrasound (R-EUS) scans are the most commonly used staging tools for GC. The accuracy of linear EUS (L-EUS) in this setting is still controversial. The aim of this retrospective multicenter study was to evaluate the accuracy of L-EUS and CECT in preoperative GC staging, with regards to depth of tumor invasion (T staging) and nodal involvement (N staging). MATERIALS AND METHODS: 191 consecutive patients who underwent surgical resection for GC were retrospectively enrolled. Preoperative staging had been performed using both L-EUS and CECT, and the results were compared to postoperative staging by histopathologic analysis of surgical specimens. RESULTS: L-EUS diagnostic accuracy for depth of invasion of the GC was 100%, 60%, 74%, and 80% for T1, T2, T3, and T4, respectively. CECT accuracy for T staging was 78%, 55%, 45%, and 10% for T1, T2, T3, and T4, respectively. L-EUS diagnostic accuracy for N staging of GC was 85%, significantly higher than CECT accuracy (61%). CONCLUSIONS: Our data suggest that L-EUS has a higher accuracy than CECT in preoperative T and N staging of GC.
RESUMEN
BACKGROUND AND AIM: Very low-volume bowel preparation (BP) for colonoscopy with 1-liter polyethylene glycol plus ascorbate (1L-PEG-Asc) has displayed high tolerability and quality of bowel cleansing. Concerns have been raised regarding its safety. We aimed to evaluate the incidence of adverse events (AEs) following BP with 1L-PEG-Asc or 2L-PEG-Asc. PATIENTS AND METHODS: From January 2019 to September 2020, data from all consecutive adult outpatients who underwent colonoscopy in Our Unit were collected. AEs were assessed by reviewing the clinical and laboratory data of patients who attended the Emergency Department (ED) of Modena District Hospitals in the 7 days following the colonoscopy, and were classified as "BP-related" or "BP-unrelated". RESULTS: During the study, 4069 (68.03%) and 1912 (31.97%) patients underwent colonoscopy after taking 2L-PEG-Asc or 1L-PEG-Asc, respectively. Regarding AEs, 77 (1.29%) patients attended ED, 53 (53/4069, 1.30%) and 24 (24/1912, 1.25%) after taking 2L-PEG-Asc and 1L-PEG-Asc. BP-related AEs were observed in 5 (5/4069, 0.12%) and 4 (4/1912, 0.21%) patients, respectively. The most frequent BP-related AEs were tachyarrhythmias (6/5981, 0.10%). CONCLUSION: The incidence rate of clinically relevant BP-related AEs is extremely low. This strongly suggests that 1L-PEG-Asc colonoscopy BP is as safe as 2L-PEG-Asc BP in a real-life clinical setting of unselected patients.

BACKGROUND: Several scientific societies have endorsed non-anesthesiologist sedation (NAS) during gastrointestinal endoscopy, considering it a safe procedure when administered by adequately trained personnel. This study aimed to evaluate the occurrence of adverse events after implementation of the European Society of Gastrointestinal Endoscopy (ESGE) and European Society of Gastroenterology and Endoscopy Nurses and Associates (ESGENA) sedation training program. METHODS: From January 2017 to August 2018, data from all consecutive endoscopic procedures in adults (≥â18 years) performed at our endoscopy unit were collected using an electronic reporting system. RESULTS: All staff (physicians and nurses) completed the ESGE-ESGENA sedation course. In total, 12â 132 patients underwent endoscopic procedures, 10â755 (88.6â%) of which were performed in a non-anesthesiological setting. Of these, about 20â% used moderate sedation with midazolam + fentanyl and 80â% used deep sedation with additional propofol. No sentinel, 5 (0.05â%) moderate risk, and 18 (0.17â%) minor risk adverse events occurred, all during moderate or deep sedation, and all managed by endoscopy staff without the need for anesthesiologist assistance. CONCLUSIONS: After completing the ESGE-ESGENA sedation training program, the rate of adverse events was very low in our institution. The findings support implementation of the program in all digestive endoscopy units and inclusion in the curriculum for physicians and nurses to ensure safe endoscopic procedures.

RESUMEN
BACKGROUND: Although bowel preparation before colonoscopy and capsule endoscopy is widely evaluated and usually follows established guidelines, a standard preparation regime for peroral small bowel enteroscopy is yet to be defined.The aim of the present study was to compare small bowel preparation with polyethylene glycol (PEG) and "fasting only" (FO) before peroral single-balloon enteroscopy (SBE). STUDY: We compared small bowel preparation with PEG versus "FO" for peroral SBE in a randomized European multicenter trial. Patients' and procedural characteristics were documented and carefully analyzed. Primary endpoint was the oral intubation depth of the small bowel. A modified Boston preparation scale was used to assess bowel cleansing as a secondary endpoint. RESULTS: In total, 43 patients were enrolled in this study (FO group: n=25; PEG group: n=18). In both groups, patients' characteristics were comparable. The indications for oral enteroscopy were equally distributed in both groups (P=0.894). The oral intubation depth was significantly higher in the PEG versus the FO group (261±87 vs. 203±66 cm; P=0.019; mean±SD), while the quality of bowel preparation was equally sufficient in both groups [complete visualization of the mucosa (Boston preparation scale) 83% versus 76% (P=1.000)]. CONCLUSIONS: Small bowel preparation with PEG for SBE yields significantly deeper intubation as compared with "FO" preparation. As patient comfort and safety was similar in both groups, PEG preparation might be favored, especially if deep intubation of the small bowel is desired. For patients requiring visualization of the proximal jejunum, a FO preparation seems to be sufficient.

OBJECTIVES: Contrast-enhanced ultrasonography (CEUS) allows the study of vascularization of secondary liver lesions. The Cyberknife (Accuray, Inc, Sunnyvale, CA) is a therapeutic method that allows a tumor target to be subjected to a high radiant dose gradient. This prospective pilot study aimed to demonstrate the concordance of CEUS versus contrast-enhanced computed tomography (CECT) in determining the stability or disease progression of secondary liver lesions after treatment with the Cyberknife. METHODS: Twenty-four patients were consecutively enrolled, and 3 different operators evaluated the CEUS images and the intermodality concordance with CECT. All patients received CEUS at 1 and 2 months after the Cyberknife therapy. The intermodality agreement was evaluated by the Cohen κ coefficient and a multivariate analysis according to the method of Janson and Olsson (Educ Psychol Meas 2001; 61:277-289). RESULTS: Forty secondary liver lesions were detected and treated. Forty-one CECT and 51 CEUS examinations were performed without any adverse events in the 24 patients. The intermodality agreement rates, calculated for the operators as Cohen κ values, were κ = 1.00, 0.881, and 0.767, respectively. The multivariate analysis of intermodality agreement showed an almost perfect value (ι = 0.841). CONCLUSIONS: This pilot study found excellent diagnostic correspondence between CEUS and CECT in the evaluation of local disease stability or progression after Cyberknife therapy in liver metastases. These findings suggest that CEUS could play an important role in the surveillance of these patients because of its high accuracy and reproducibility, thus reducing the need for CECT.

BACKGROUND: The assessment of fibrosis degree in liver diseases is based on several non-invasive techniques, but none has been accurate. AIM: This study employed proton nuclear magnetic resonance spectroscopy to identify metabolic profiles in serum and urine, specific for different fibrosis degree in chronic hepatitis C patients. METHOD: 71 plasma, 73 serum, and 578 urine samples were collected. All samples were analyzed using 1H-NMR spectroscopy technique and three different NMR spectra were acquired for each serum/plasma sample. The data analyses were performed by partial least square regression, principal component analysis, and Monte Carlo cross-validation in a supervised methodology. RESULTS: The cross-validation test correctly assigned each sample to its specific donor with 98.44% accuracy for urine samples and 65% for serum/plasma samples. Advanced fibrosis and cirrhosis were recognized with 71% sensitivity for CPMG plasma spectra and 69% specificity for NOESY serum spectra. Accuracy for NOESY serum spectra was 68%. Noesy spectra recognized advanced fibrosis and cirrhosis with 71% sensitivity, 30% specificity, and 50% accuracy in urine samples. CONCLUSION: Metabolomic analysis of urine spectra using 1H-NMR spectroscopy can recognize a specific individual profile in all patients with chronic hepatitis C. However, this method cannot yet differentiate with sufficient accuracy, patients with advanced fibrosis from patients with milder disease.

The introduction of biological agents has revolutionized the management of many life-threatening and debilitating immune-mediated diseases. Because of the high cost of biological drugs and their patent expiration, the market has opened to biosimilar agents, copy versions of the originators, which can lead to reduced health care expenditure and increase treatment access worldwide. CT-P13 is the first biosimilar of infliximab (IFX) and has been approved for the same indications as its originator drug. It obtained regulatory approval by the European Medicines Agency in September 2013 and by the US Food and Drug Administration in April 2016. The Phase I and Phase III clinical trials conducted in ankylosing spondylitis and rheumatoid arthritis have demonstrated pharmacokinetic and efficacy equivalence with comparable safety and immunogenicity to IFX. For these reasons, the use of CT-P13 has been extrapolated also to inflammatory bowel disease. There have been some initial concerns regarding the use of CT-P13 in inflammatory bowel disease patients, because of the lack of randomized controlled trials. However, emerging real-world data have further confirmed the comparability between CT-P13 and its reference product in terms of efficacy, safety, and immunogenicity, in patients naïve to the anti-tumor necrosis factor alpha agents and after switching from IFX, and will be summarized in this review.

BACKGROUND AND STUDY AIMS: Percutaneous placement of fiducial markers is required to perform stereotactic body radiation therapy (SBRT) for liver neoplastic lesions. This prospective trial was designed to evaluate the feasibility and safety of percutaneous ultrasound-guided placement of three different types of markers in patients with liver cancer referred for SBRT. PATIENTS AND METHODS: Fifty patients underwent percutaneous ultrasound-guided implantation of a fiducial marker in the liver. Three sizes of needles were used: 25 gauge (G), 22G, and 17G. The 25G and 22G needles contained gold anchor markers of 0.28×10mm and 0.4 ×10mm size, respectively. In contrast, the 17G needle contained a gold grain marker of 1×4mm. Each patient received 1-6 markers, depending on lesion size and numbers. Technical feasibility and the occurrence of adverse events were registered. Computed tomography scans were acquired prior to SBRT to evaluate the location, visibility, or complications related to the markers. RESULTS: A total of 163 needles were used to deliver 163 markers in 50 patients. No major complications occurred. Minor complication occurrence rate was 12%. The total complication occurrence for all type of markers was 8.5%. No complications were observed with the use of the gold anchor marker of 0.4 ×10mm size. Variance analysis of the three markers showed a significant difference in the frequency of complications amongst the three markers (p<0.01). CONCLUSION: Percutaneous ultrasound-guided placement of fiducial markers for SBRT of liver neoplastic lesions is safe and feasible. In our series, the 22G needle showed some advantage in terms of handling and safety when compared with the 25G and 17G needles. In addition, the gold anchor marker of 0.4 ×10mm size displayed a lower percentage of displacement.
