RESUMEN
BACKGROUND AND AIMS: The optimal endoscopic resection method of challenging colorectal lesions (ie, adenomatous recurrences, nongranular laterally spreading tumors [LST-NGs], lesions without lifting sign <30 mm) is still under debate. The aim of this study was to directly compare endoscopic submucosal dissection (ESD) and endoscopic full-thickness resection (EFTR) for the resection of challenging colorectal lesions in a randomized trial. METHODS: A multicenter, prospective, randomized study was performed in 4 Italian referral centers. Consecutive patients referred for endoscopic resection of challenging lesions were randomly assigned to undergo EFTR or ESD. Primary outcomes were complete (R0) resection and en bloc resection of lesions. Technical success, procedure time, procedure speed, area of the resected specimen, adverse event rate, and local recurrence rate at 6 months were also compared. RESULTS: Overall, 90 patients were included in the study, equally representing the 3 challenging lesion types. Age and sex were comparable in the 2 groups. En bloc resection was obtained in 95.5% of the EFTR group and in 93.3% of the ESD group. R0 resection rate was comparable in the 2 groups (EFTR vs ESD, 42 [93.3%] vs 36 [80%]; P = .06). The EFTR group exhibited a significantly shorter total procedure time (25.6 ± 10.6 minutes vs 76.7 ± 26.4 minutes, P ≤ .01), as well as overall procedure speed (16.8 ± 11.8 mm2/min vs 11.9 ± 9.2 mm2/min, P = .03). The EFTR group had a significantly smaller mean lesion size (21.6 ± 8.3 mm vs 28.7 ± 7.7 mm, P ≤ .01). Adverse events were reported less frequently in patients in the EFTR group (4.44% vs 15.5%, P = .04). CONCLUSIONS: EFTR is comparable to ESD in the treatment of challenging colorectal lesions in terms of safety and efficacy. EFTR is considerably faster than ESD in the treatment of nonlifting lesions and adenoma recurrences. (Clinical trial registration number: NCT05502276.).

Background and Objectives: Conflicting evidence is reported regarding any association between colonic diverticula with colorectal adenomas or cancer. The present study aimed to evaluate, in a cohort of Caucasian patients, the association between colonic diverticula and colorectal polyps and cancer. Materials and Methods: All consecutive patients undergoing colonoscopy at our institution were included in the study. The presence and location of diverticula, polyps, and cancers were recorded. Histologically, polyps were classified as adenoma (with low or high dysplasia), hyperplastic, or inflammatory. The relative risk of the association of polyps and cancer with diverticula was assessed. Multiple logistic regression analyses, including age, sex, family history for colorectal cancer (CRC), and family history for diverticula, were carried out. Results: During the study period, 1490 patients were enrolled; 37.2% (n = 555) showed colonic diverticula or polyps or CRC (308 males, mean age 66 years). Particularly, 12.3% (n = 183) patients presented only diverticula, 13.7% (n = 204) only polyps or cancer, 11.3% (n = 168) both diseases, and 62.7% (n = 935) neither diverticula nor polyps and cancer. A total of 38 patients presented colorectal cancer, 17 of which had also diverticula. A significant increase in relative risk (RR 2.81, 95% CI 2.27-3.47, p < 0.0001) of colorectal adenoma and cancer in patients with colonic diverticula was found. At multivariate analysis, only diverticula resulted to be significantly associated with colorectal adenomas and cancer (Odds Ratio, OR 3.86, 95% CI 2.90-5.14, p < 0.0001). Conclusions: A significant association of colonic diverticula with colorectal adenoma or cancer was found. This implies that patients with colonic diverticula require a vigilant follow-up procedure for the prevention of colorectal cancer from those applicable to the general population.

Objectives: Colonoscopy is the gold standard diagnostic method for colorectal cancer (CRC) screening. Despite the progress in the endoscopy technology field, a small percentage of colonoscopies is still incomplete. The reasons for that are mostly associated with anatomic features, such as fixed, angulated, long and loopy colon, intra-abdominal adherences and female gender. To overcome such difficulties, the usefulness of scopes different from conventional adult colonoscope (CF), such as paediatric colonoscope (PCF), gastroscope (GIF), single and double balloon enteroscope (SBE and DBE, respectively), has been shown in literature. Our retrospective study aims to evaluate the caecal intubation rate using a SBE without the overtube in patients who previously underwent an incomplete procedure with a different scope.Methods: Patients with a previous incomplete colonoscopy with CF, PCF or GIF were retrospectively enrolled through the analysis of a dedicated database. The enteroscope used was the Olympus Enteropro Single Balloon SiF-Q180 with no overtube. Complete colonoscopy was defined as successful caecal intubation.Results: SBE was used to scope 47 adult patients, mostly female, and it led to a complete procedure in 91% of them. The most frequent reason for an incomplete procedure even with the use of SBE was a fixed and angulated colon.Conclusions: Colonoscopy performed with SBE was safe and no adverse events during and/or after the procedure occurred. Our results suggest that SBE with no overtube is a useful and valid alternative to other type of scopes in difficult cases, especially those related to fixed/angulated colon and in female gender.

OBJECTIVES: Single balloon enteroscopy (SBE) is an effective and safe modality for the diagnosis and therapeutic intervention of small bowel disorders. Its use in patients with Crohn's disease (CD) and particularly its effect on management changes in CD have not yet been determined. MATERIALS AND METHODS: We performed a retrospective review of the endoscopic and clinical data available on a cohort of patients with small bowel CD who had undergone SBE to determine the diagnostic and therapeutic yield of the procedure and the initial and longer-term impact it had on clinical management. RESULTS: About 52 patients have undergone SBE in our unit for the investigation of known (n = 39) or suspected (n = 13) small bowel CD with a diagnostic yield of 77% and 39%, respectively. SBE had an immediate clinical impact in 69% (n = 33) of patients, including dilatation of a stricture in 27% (n = 13), initiation or adjustment of dose of medications in 48% (n = 23), referral for surgical resection in 6% (n = 3). Moreover, the procedure permitted determining a new diagnosis of CD in 8% of the patients (n = 4), and excluding it in 8% (n = 4). Longer term follow-up was available in 34 patients (65%) which showed a significant difference in mean HBI score from 6.6 before the procedure to 4.2 after it (p < .0001). CONCLUSIONS: SBE has a high diagnostic and therapeutic yield in CD and significantly impacts disease management. Careful patient selection is a key factor in optimizing its use in CD.

OBJECTIVE: We investigate the efficiency of endoscopic mucosal resection (EMR) of non-ampullary sporadic duodenal adenomas (NASDA) in a retrospective analysis with long-term follow-up. METHODS: Consecutive patients undergoing EMR of NASDA between May 2002 and December 2016 were retrospectively identified from an electronic database. Endoscopic follow-up was scheduled after 3, 6 and 12 months for the first year, then yearly for up to five years. RESULTS: EMR of 75 NASDA was performed in 68 patients (56% en-bloc, 44% piecemeal). Retroperitoneal perforations occurred in 3/68 (4.4%) patients, were treated by surgical (n = 2) or percutaneous (n = 1) drainage; delayed bleeding was reported in 13/75 (17.3%) resections and was successfully managed by endoscopy (n = 12) or radiologic embolization (n = 1). There was no procedure-related mortality. Follow-up was available in 61/68 patients (89.7%) after a median time of 59 months from resection. Residual and recurrent adenoma were diagnosed in 9 (14.5%) and 6 (10.9%) cases, respectively; all but one were successfully retreated endoscopically. CONCLUSIONS: EMR for NASDA is effective with a favorable long-term outcome. Local recurrences can be retreated endoscopically. A recall system, patient's compliance to endoscopic follow-up are mandatory to detect recurrences and their prompt treatment.

BACKGROUND: Non-celiac gluten sensitivity (NCGS) is a recently recognized disorder, characterized by the occurrence of symptoms following gluten ingestion. It is often self-diagnosed by the patient, but should be confirmed by the response to a gluten-free diet, followed by a gluten challenge. Celiac disease (CD) and wheat allergy (WA) must first be ruled out. AIMS: (1) to determine the frequency of visits performed for symptoms self-perceived as gluten-related; (2) to assess in this cohort, the proportion of patients satisfying the diagnostic criteria for NCGS. METHODS: A two-year prospective study including all consecutive patients complaining of gluten-related symptoms. NCGS was diagnosed on the basis of the disappearance of the symptoms within 6 months of a gluten-free diet, followed by their reappearance with the reintroduction of gluten in the diet for 1 month. RESULTS: Three hundred and ninety two patients complaining of gluten-related symptoms were enrolled; 26 of these (6.63%) were affected by CD, 2 (0.51%) by WA and 27 were diagnosed with NCGS (6.88%). The remaining 337 patients (85.96%) did not experience any change of symptoms with a gluten-free diet. The PPV of the gluten-related symptom was found to be 7%. CONCLUSION: Eighty six percent of patients reporting gluten-related symptoms have neither NCGS, nor CD, nor WA. Self-perceived gluten-related symptoms are rarely indicative of the presence of NCGS.

BACKGROUND: Intramural duodenal hematoma is a rare condition described for the first time in 1838. This condition is usually associated with blunt abdominal trauma in children. Other non-traumatic risk factors for spontaneous duodenal haematoma include several pancreatic diseases, coagulation disorders, malignancy, collagenosis, peptic ulcers, vasculitis and upper endoscopy procedures. In adults the most common risk factor reported is anticoagulation therapy. The clinical presentation may vary from mild abdominal pain to acute abdomen and intestinal obstruction or gastrointestinal bleeding. CASE SUMMARY: The aim of this case summary is to show a case of intramural spontaneous hematoma with symptoms of intestinal obstruction that was properly drained endoscopically by an innovative system lumen-apposing metal stent Hot AXIOS™ stent (Boston Scientific Corp., Marlborough, MA, United States). CONCLUSION: Endoscopic lumen-apposing metal stent Hot AXIOS™ stent is a safe and feasible treatment of duodenal intramural hematoma in our case.

Background and study aims Feasibility of EUS-guided choledochoduodenostomy (EUS-CDS) using available lumen-apposing stents (LAMS) is limited by the size of the common bile duct (CBD) (≤â12âmm, cut-off for experts; 15âmm, cut-off for non-experts). We aimed to assess the prevalence and predictive factors associated with CBD size ≥â12 and 15âmm in naïve patients with malignant distal biliary obstruction (MDBO). Patients and methods This was a prospective cohort study involving 22 centers with assessment of CBD diameter and subjective feasibility of the EUS-CDS performance in naïve jaundiced patients undergoing EUS evaluation for MDBO. Results A total of 491 patients (mean age 69â±â12 years) with mean serum bilirubin of 12.7â±â6.6âmg/dL entered the final analysis. Dilation of the CBD ≥â12 and 15âmm was detected in 78.8â% and 51.9â% of cases, respectively. Subjective feasibility of EUS-CDS was expressed by endosonographers in 91.2â% for a CBD ≥â12âmm and in 96.5â% for a CBD ≥â15âmm. On multivariate analysis, age ( P â<â0.01) and bilirubin level ( P â≤â0.001) were the only factors associated with both CBD dilationâ≥â12 andâ≥â15âmm. These variables were poorly associated with the extent of duct dilation; however, based on them a prediction model could be constructed that satisfactorily predicted CBD size ≥â12âmm in patients at least 70 years and a bilirubin level ≥â7âmg/dL. Conclusions Our study showed that at presentation in a large cohort of patients with MDBO, EUS-CDS can be potentially performed in three quarters to half of cases by expert and less experienced endosonographers, respectively. Dedicated stents or devices with different designs able to overcome the limitations of existing electrocautery-enhanced LAMS for EUS-CDS are needed.
RESUMEN
BACKGROUND: The premalignant nature of ampullary adenomas justifies their radical excision. AIMS: Aim of this study is to evaluate the long-term results of endoscopic snare papillectomy in a consecutive series of patients with ampullary adenomas. METHODS: Patients who underwent endoscopic snare papillectomy between October 1999 and October 2017 were identified from an electronic database. Endoscopic snare papillectomy was performed en bloc, when possible; a pancreatic stent or a nasopancreatic drainage were inserted. Endoscopic follow-up was scheduled after 3, 6 and 12 months for the first year, then yearly. RESULTS: Endoscopic snare papillectomy was performed in 135 patients (70 M, mean age 60.5 years) by en bloc (83%) or piecemeal (17%) resection. Delayed bleeding occurred in 16 patients (11.8%), infected retroperitoneal collections in 6 patients (4.4%), pancreatitis in 4 patients (3%). One patient died (0.7%). Follow-up was available in 103/114 (90.3%) patients. In case of residual (24.3%) and recurrent (23.3%), adenomas endoscopic retreatment was successful in 42/49 cases (85.7%). After a mean follow-up of 40 months, 93.2% (96/103) of the patients were disease free CONCLUSION: Endoscopic snare papillectomy of ampullary adenomas is effective with favorable long-term outcomes. Compliance to the scheduled follow-up is important for the early detection and re-treatment of recurrences.

BACKGROUND: Celiac disease (CD) often manifests with dyspeptic symptoms and chronic gastritis is a common finding. AIM: To evaluate the frequency of lymphocytic gastritis (LG), chronic active gastritis (CAG), and chronic inactive gastritis (CIG) in patients with CD, before and after gluten-free diet (GFD). METHODS: A five-year prospective study including all consecutive patients with a new diagnosis of CD was conducted. Gastric and duodenal biopsy specimens taken both at the time of the CD diagnosis and at the first endoscopic control after 18-24 months on GFD were evaluated. RESULTS: 213 patients with CD were enrolled. At the time of the diagnosis, 42 patients (19.7%) showed normal gastric mucosa, 34 (15.9%) LG, 67 (31.5%) CAG, and 70 (32.9%) CIG. Out of the 34 patients with LG, all were Helicobacter pylori negative and the majority of them showed an improvement both of gastritis (94.1%) and duodenal lesions (82.3%) after GFD. GFD did not show significant effects on CAG and CIG. CONCLUSIONS: LG is present in 16% of CD patients, it is not associated with H. pylori infection, and it improves after GFD. Both CAG and CIG are also frequently associated with CD, but fail to respond to a GFD.
