ABSTRACT

Colorectal cancer emerged as the third most prevalent malignancy worldwide, affecting nearly 2 million individuals in the year 2020. This study elucidates the pivotal role of a multidisciplinary team (MDT) in influencing the prognosis, as measured by relative survival rates, depending upon the stage and age. Cases recorded in an Italian Cancer Registry between 2017 and 2018 were included. Relative survival was reported at 1 and 3 years after diagnosis comparing MDT vs. no-MDT approaches. During the study period, 605 CRCs were recorded while 361 (59.7%) were taken care of by an MDT. Compared to no-MDT, MDT patients were younger with earlier stages and received more surgery. One year after diagnosis, survival was 78.7% (90% in MDT vs. 62% in no-MDT); stratifying by stage, in the MDT group there was no survival advantage for stage I (97.2% vs. 89.9%) and II (96.8% vs. 89.4%), but an advantage was observed for stage III (86.4% vs. 56.9%) and stage IV (63.7% vs. 27.4%). Similar values were observed at 3 years where a marked advantage was observed for stages III (69.9% vs. 35.1%) and IV (29.2% vs. 5.1%). The univariable analysis confirmed an excess risk in the no-MDT group (HR 2.6; 95% CI 2.0-3.3), also confirmed in the multivariable regression analysis (HR 2.0; 95% CI 1.5-2.5). Despite the increase in the number of MDT patients in 2018 (from 50% to 69%), this does not correspond to an improvement in outcome.

ABSTRACT

BACKGROUND AND AIMS: To investigate the effectiveness of double-balloon enteroscope-assisted retrograde cholangiopancreatography (DBE-ERCP) in patients with gastrointestinal surgically altered anatomy (SAA). METHODS: From May 2013 to October 2021, all consecutive patients undergoing DBE-ERCP in three gastroenterological referral centers in Northern Italy were enrolled in the study. Patients were assessed regarding their medical history, previous surgery, time from previous surgery to the DBE-ERCP procedure, and the success or failure of DBE-ERCP. RESULTS: Fifty-three patients (60% men, median age 65 (23-89) years) undergoing 67 DBE-ERCP procedures (1-3 DBE-ERCP per patient) were enrolled. Reasons for SAA included orthotopic liver transplantation (23%), ulcers (15%), malignancies (43%), difficult cholecystectomy (17%), and other causes (2%). Types of surgery included Roux-en-Y biliodigestive anastomosis (45%), Roux-en-Y gastrectomy (32%), pancreaticoduodenectomy (17%), and Billroth II gastrectomy (6%). The overall DBE-ERCP success rate was 86%. The type of surgery, indications, and the length of time between previous surgery and DBE-ERCP were not statistically associated with DBE-ERCP success. The DBE-ERCP success rate increased from 2018 to 2021. CONCLUSIONS: DBE-ERCP is a successful procedure in challenging patients with SAA. The improvement in results over time indicates the necessity of adequate training and of centralizing patients in referral centers.

ABSTRACT

Background and study aims Fusion imaging consists of overlaying preoperative imaging over live fluoroscopy, providing an augmented live guidance. Since 2017, we have been using a new hybrid operating room (Discovery IGS 740 OR, GE Healthcare) for biliopancreatic endoscopy, combining fusion imaging with traditional endoscopic ultrasound (EUS). This study aimed to assess the advantages that fusion imaging could bring to EUS-guided drainage of post-pancreatitis fluid collections. Patients and methods Thirty-five drainage procedures performed between 2012 and 2019 with traditional guidance and fusion imaging were retrospectively compared, assessing the overall treatment success rate - i. e. symptom improvement with complete PFC emptying - as a primary outcome. Secondary outcomes included technical success rate, time to resolution, hospital stay length, adverse events, recurrence rate, and procedure time. Results Patients treated with standard EUS (n = 17) and with fusion imaging (n = 18) were homogeneous in age, gender, pancreatitis etiology, and indication for drainage; the second group had larger PFCs, more frequently walled-off necrosis than pseudocysts, and were treated more emergently, indicating higher case complexity in this group. During the period when fusion imaging was adopted, procedures had a higher overall treatment success rate than during the period when standard EUS was adopted (83.3 % vs. 52.9 %, P  = 0.075), and complete emptying was reached in less time (61.1 % vs. 23.6 % complete emptying within 90 days, P  = 0.154), differences compatible with random fluctuations. Conclusions This study suggests that fusion imaging in combination with EUS might improve clinical and procedural outcomes of PFC drainage.

ABSTRACT

BACKGROUND: Ampullary adenomas are rare and potentially malignant. Surgery was the standard treatment but endoscopic papillectomy (EP) is a possible alternative. AIM: We retrospectively evaluated the principal clinical outcomes of EP in all patients referred to our unit also dividing sporadic ampullary adenoma (SAA) from familial adenomatous polyposis (FAP)-associated adenomas. METHODS: All consecutive patients who underwent endoscopic papillectomy because of ampullary adenoma were considered. The primary outcome was the technical success of EP. Secondary outcomes included the number of procedures, the adverse event rate, the recurrence rate, the concordance of histology pre- and post-EP, and the evaluation of factors related to technical success. RESULTS: Between January 2001 and December 2015, sixty-two patients were included (21 FAP and 41 SAA). Technical success was achieved in 75.8% and was different in the two groups (FAP 95.2%, SAA 65.8%, p 0.025). Intraductal invasion was negatively associated with technical success (41.7% vs. 84.0%; p 0.005). The intestinal subtype was predictive of success (79.7% vs. 0%; p 0.012) as well as en bloc resection (90.3% vs. 61.3%; p 0.016). Adverse events were reported in 14 patients (22.6%). CONCLUSIONS: EP is an effective and safe procedure and is a viable alternative to surgery. TRIAL REGISTRATION: ClinicalTrials.gov Identifier: NCT03494543.

ABSTRACT

BACKGROUND: Endoscopic retrograde cholangiopancreatography (ERCP) with the placement of a biliary stent is the treatment of choice for palliation of malignant obstructive jaundice. In 5-10% of cases ERCP fails. In these cases an effective alternative is endoscopic ultrasonography-guided biliary drainage (EUS-BD). AIM: Evaluation of the principal clinical outcomes of direct transluminal EUS-BD. PATIENTS AND METHODS: This study is a retrospective analysis. All consecutive patients with malignant obstructive jaundice, in whom ERCP had failed, were enrolled. The primary outcome was the technical success of EUS-BD defined as the correct placement of the metal or plastic stent across the stomach or duodenum to the biliary tree. The most important secondary outcomes were early and late clinical success, both linked to the decrease of bilirubin haematic level. RESULTS: Between January 2011 and November 2017 thirty-six patients were included. Technical success was obtained in 91.6%. A clinical success, early or late was obtained in 75.8%. The ECOG performance status of less than 3 was correlated with clinical success. Adverse events occurred in 30.3% of patients. CONCLUSIONS: EUS-BD is an effective and safe procedure.

ABSTRACT

AIM: To determine the efficacy of our therapeutic strategy for Helicobacter pylori (H. pylori) eradication and to identify predictive factors for successful eradication. METHODS: From April 2006 to June 2010, we retrospectively assessed 2428 consecutive patients (1025 men, 1403 women; mean age 55 years, age range 18-92 years) with gastric histology positive for H. pylori infection referred to our unit for 13-C urea breath test (UBT), after first-line therapy with proton pump inhibitor (PPI) b.i.d. + amoxicillin 1 g b.i.d. + clarithromycin 500 mg b.i.d. for 7 d. Patients who were still positive to UBT were recommended a second-line therapy (PPI b.i.d. + amoxicillin 1 g b.i.d. + tinidazole 500 mg b.i.d. for 14 d). Third choice treatment was empirical with PPI b.i.d. + amoxicillin 1 g b.i.d. + levofloxacin 250 mg b.i.d. for 14 d. RESULTS: Out of 614 patients, still H. pylori-positive after first-line therapy, only 326 and 19 patients respectively rechecked their H. pylori status by UBT after the suggested second and third-line regimens. "Per protocol" eradication rates for first, second and third-line therapy were 74.7% (95% CI: 72.7%-76.4%), 85.3% (95% CI: 81.1%-89.1%) and 89.5% (95% CI: 74.9%-103%) respectively. The overall percentage of patients with H. pylori eradicated after two treatments was 97.8% (95% CI: 97.1%-98.4%), vs 99.9% (95% CI: 99.8%-100%) after three treatments. The study found that eradication therapy was most effective in patients with ulcer disease (P < 0.05, P = 0.028), especially in those with duodenal ulcer. Smoking habits did not significantly affect the eradication rate. CONCLUSION: First-line therapy with amoxicillin and clarithromycin produces an H. pylori eradication rate comparable or superior to other studies and second-line treatment can still be triple therapy with amoxicillin and tinidazole.

ABSTRACT

PURPOSE: In this report, we compared endoscopic ultrasonography (EUS), multidetector CT (MDCT), and Ga-68 DOTATOC PET/CT in patients with neuroendocrine tumors (NETs). We report our experience with use of these methods in patients suspected to have duodenopancreatic primitive NET. METHODS: Nineteen consecutive patients (mean age, 56; 21-80), who underwent both Ga-68 DOTATOC PET/CT and EUS between March 2007 and November 2008 were retrospectively included in the study (16 underwent MDCT). Suspicion of NET was confirmed by EUS-FNA and/or surgery. Operative characteristics of PET, EUS, and MDCT were compared. RESULTS: Twenty-three neuroendocrine lesions were diagnosed in 13/19 patients. EUS, PET, and MDCT correctly identified as affected 13/13 (100%), 12/13 (92%), and 10/11 (91%) patients, respectively. On a lesion basis, EUS, PET, and MDCT identified correctly as NETs 22/23 (96%), 20/23 (87%), and 13/18 (72%) lesions (P = 0.08 EUS vs. CT). Both on a patient and on a lesion basis, specificity was 67%, 83%, and 80% for EUS, PET, and MDCT, respectively. CONCLUSIONS: EUS, Ga-68 DOTATOC PET, and MDCT seem to have comparable accuracy in diagnosis of duodenopancreatic NET and their combination may allow an optimal preoperative diagnosis.

ABSTRACT

BACKGROUND: Curcumin is the principal element of turmeric powder extracted from the root of Curcuma longa. Studies on curcumin have demonstrated some anti-Helicobacter pylori activity as well as immunomodulating properties. N-acetylcysteine and lactoferrin with their respective mucolytic and antibacterial activities might also be effective in H. pylori eradication therapy. AIM: To determine if a 7-day non-antibiotic therapy comprised of curcumin, lactoferrin, N-acetylcysteine, and pantoprazole was effective for eradication of H. pylori infection and reduction of gastric inflammation, assessed by serum pepsinogens and relief of symptoms. SUBJECTS AND METHODS: Twenty-five consecutive H. pylori-positive patients (12 males, mean age 50 +/- 12 years, range 31-76) with functional dyspepsia were enrolled. Patients were administered for 7 days curcumin 30 mg b.i.d., bovine lactoferrin 100 mg b.i.d., N-acetylcysteine 600 mg b.i.d., and pantoprazole 20 mg b.i.d. H. pylori status and upper gastrointestinal symptoms were assessed by (13)C-urea breath test and a scale of upper gastrointestinal symptoms intensity (absent, mild, moderate, and severe), as well as a blood test for serum pepsinogens (sPGI, sPGII), gastrin-17 (G-17), and anti-H. pylori IgG (IgG-Hp) at baseline (T0) and after 2 months (T1). RESULTS: Three of 25 patients (12%) were cured of H. pylori infection. A significant decrease in the overall severity of symptoms (T0: 6, interquartile range [IQR]: 4.5-8; T1: 2, IQR: 2-3; p < or = .001), and sPGII (T0: 16 microg/L, IQR: 13-22; T1: 10 microg/L, IQR: 8-16; p < or = .001) and sPGI (T0: 82 microg/L, IQR: 67-97; T1: 74 microg/L, IQR: 62-94; p = .02) levels were observed after 2 months of the treatment. IgG and G-17 values did not significantly decrease after 2 months. CONCLUSIONS: This novel therapy was not effective for H. pylori eradication. However, despite the bacterium persistence, significant improvement of dyspeptic symptoms and reduction of serologic signs of gastric inflammation were observed after 2 months at the end of the 7-day treatment schedule.

ABSTRACT

In uncomplicated diverticular disease, treatment is aimed at relieving symptoms. The aim of the present study was to evaluate the efficacy of mesalazine for symptomatic relief of uncomplicated diverticular disease of the colon. Two hundred sixty-eight consecutive eligible outpatients (122 male, 146 female; age, 66.1 years; range, 31-81 years) were enrolled in four treatment schedules in a randomized fashion: Group R1 (66 patients), rifaximin, 200 mg bid; Group R2 (69 patients), rifaximin, 400 mg bid; Group M1 (67 patients), mesalazine, 400 mg bid; and Group M2 (66 patients), mesalazine, 800 mg bid. Treatments were administered for 10 days every month for 12 months. Clinical evaluations were performed at admission and at 3-month intervals for 12 months considering 12 clinical variables (upper and lower abdominal pain/discomfort, tenesmus, diarrhea, abdominal tenderness, fever, bloating, general illness, nausea, emesis, dysuria, bleeding) graded as 0 = no symptoms, 1 = mild, 2 = moderate, and 3 = severe. The Global Symptomatic Score (GSS) was calculated using the sum of each symptom score. Two hundred forty-four patients completed the 12- month study; 24 were discontinued (14 treated with rifaximin and 10 treated with mesalazine) either as voluntary dropouts or because they developed side effects and/or complications. Group M2 demonstrated a lower frequency of many symptoms after 6 and 12 months of treatment; the mean GSS was significantly lower in Group M2 after 6 and 12 months of therapy by both intention-to-treat and per-protocol analyses. Patients treated with mesalazine (Groups M1+M2) had a lower GSS than subjects treated with rifaximin (Groups R1+R2) during the 12-month follow-up period. We conclude that cyclic administration of mesalazine is effective for symptomatic relief of uncomplicated diverticular disease of the colon. Some symptoms showed greater improvement with mesalazine, 800 mg bid, than with the other treatment schedules.

ABSTRACT

BACKGROUND: Even though the cause of irritable bowel sindrome (IBS) is not yet known, alterations of the intestinal microflora may be important in its pathogenesis. AIM: To evaluate the efficacy of rifaximine alone or in association with the probiotic strain of Bifidobacterium longum W11 in reducing symptoms in patients with IBS. METHODS: We performed a monocentric, prospective, randomized open trial including 70 patients randomized in to two groups: Group A (41 patients) receiving rifaximin 200 (2 cp bid for ten days in a month) followed by a formulation of the probiotic strain of Bifidobacterium longum W11(one granulated suspension for 6 days on alternate weeks ) and Group B (29 patients) receiving only rifaximin 200 (2 cp bid for ten days in a month). The clinical evaluation was performed at admission and after 2-months, taking into account the method of visual analogous. RESULTS: At the 2-month follow-up, Group A patients reported a greater improvement of symptoms compared to patients in group B (p = 0.010) even if the physician's opinion at T1 did not confirm these results (p = 0.07). CONCLUSION: The increased colonisation by Bifi-dobacterium longum W11, after the cyclic administration of rifaximin, which eradicates the bacterial overgrowth of the small intestine, may reduce symptoms, especially those related to bowel habit and stool frequency in patients with IBS. The abnormalities observed in the colonic flora of IBS suggest, in fact, that a probiotic approach will ultimately be justified.

ABSTRACT

AIM: To evaluate the gastric permeability after both acute and chronic use of non-steroidal anti-inflammatory drugs (NSAIDs) and to assess the clinical usefulness of sucrose test in detecting and following NSAIDs- induced gastric damage mainly in asymptomatic patients and the efficacy of a single pantoprazole dose in chronic users. METHODS: Seventy-one consecutive patients on chronic therapy with NSAIDs were enrolled in the study and divided into groups A and B (group A receiving 40 mg pantoprazole daily, group B only receiving NSAIDs). Sucrose test was performed at baseline and after 2, 4 and 12 wk, respectively. The symptoms in the upper gastrointestinal tract were recorded. RESULTS: The patients treated with pantoprazole had sucrose excretion under the limit during the entire follow-up period. The patients without gastroprotection had sucrose excretion above the limit after 2 wk, with an increasing trend in the following weeks (P = 0.000). A number of patients in this group revealed a significantly altered gastric permeability although they were asymptomatic during the follow-up period. CONCLUSION: Sucrose test can be proposed as a valid tool for the clinical evaluation of NSAIDs- induced gastric damage in both acute and chronic therapy. This technique helps to identify patients with clinically silent gastric damages. Pantoprazole (40 mg daily) is effective and well tolerated in chronic NSAID users.

ABSTRACT

AIM: To compare peptic ulcer prevalence in patients referred for upper gastrointestinal endoscopy in two Italian hospitals in pre-Helicobacter era and ten years after the progressive diffusion of eradication therapy. METHODS: We checked all the endoscopic examinations consecutively performed in the Gastroenterology Unit of Padova during 1986-1987 and 1995-1996, and in the Gastroenterology Unit of Parma during 1992 and 2002. Chi Square test was used for statistic analysis. RESULTS: Data from both the endoscopic centers showed a statistically significant decrease in the prevalence of ulcers: from 12.7% to 6.3% (P<0.001) in Padova and from 15.6% to 12% (P<0.001) in Parma. The decrease was significant both for duodenal (from 8.8% to 4.8%, P<0.001) and gastric ulcer (3.9% to 1.5%, P<0.001) in Padova, and only for duodenal ulcer in Parma (9.2% to 6.1%, P<0.001; gastric ulcer: 6.3% to 5.8%, NS). CONCLUSION: Ten years of extensive Helicobacter pylori (H pylori) eradication in symptomatic patients led to a significant reduction in peptic ulcer prevalence. This reduction was particularly evident in Padova, where a project for the sensibilization of H pylori eradication among general practioners was carried out between 1990 and 1992. Should our hypothesis be true, H pylori eradication might in the future lead to peptic ulcer as a rare endoscopic finding.

ABSTRACT

BACKGROUND: The relationship between Helicobacter pylori (H. pylori) eradication and atrophic changes in the gastric mucosa has not yet been fully defined. Although studies report a partial restoration of serum pepsinogen I (sPGI) levels after eradication, it is not clear if this finding reflects gastric mucosal healing on a morphological level. AIM: To assess alterations in gastric function after H. pylori eradication on moderate/severe body atrophic gastritis by determination of sPGI levels. METHODS: Twenty-three dyspeptic patients, selected from 284 consecutive H. pylori positive patients, with histological features of moderate/severe body atrophic gastritis and sPGI < 25 microg/L (11 men, mean age: 51.8 years, range: 29-79 years), underwent an upper gastrointestinal endoscopy with gastric biopsies and sPGI determination at baseline. All patients underwent eradication therapy. Serum pepsinogen I was measured again after 6 months, and at 1, 2, 3 and 4 years after eradication therapy. RESULTS: Mean sPGI levels prior to eradication were 11.9 microg/L (range: 4-23 microg/L). Six months after eradication therapy, mean sPGI levels significantly increased to 17.4 microg/L (P = 0.04). At the completion of the study, 4 years after eradication, sPGI levels increased from 17.4 to 32.7 microg/L (P = 0.01). A significant progressive increase in sPGI levels was observed from 6 months to 1 year (17.4 to 23.9 microg/L) and from 1 to 2 years (23.9 to 26.0 microg/L, P = 0.01). Serum pepsinogen I levels higher than the cut-off value of 25 microg/L were observed at various time-points: 6.3% of patients at 6 months (1/16), 33.3% (5/15) at 1 year, 50% (7/14) at 24 months, 66.7% (6/9) at 36 months and 87.5% (7/8) at 4 years. CONCLUSION: After H. pylori eradication, subjects with body atrophic gastritis showed long-term improvement of physiological gastric function, reflected by significantly and continually increasing sPGI levels over a 4-year period.

ABSTRACT

It has been reported in literature that serum pepsinogen levels rise during omeprazole and lansoprazole administration. However, the influence of pantoprazole and esomeprazole on serum pepsinogens levels is still to be assessed. The aim of this study was to evaluate the influence of proton pump inhibitor (PPI) therapy on pepsinogen I (PGI) levels. PGI and gastrin (G17) levels (EIA; Biohit, Helsinki, Finland) in 126 consecutive patients (M 57; F 69, mean age 53, range 15-91), with upper gastrointestinal symptoms at baseline condition and after 2 months of PPI treatment, were evaluated. Patients underwent a therapy schedule based on: omeprazole 20 mg b.i.d. (20 patients), pantoprazole 40 mg b.i.d. (27 patients), esomeprazole 40 mg b.i.d. (29 patients), lansoprazole 30 mg b.i.d. (21 patients) and rabeprazole 20 mg b.i.d. (26 patients) for 2 months. A significant increase in serum PGI (sPGI) levels was found after a 2-month treatment for all five different PPIs: omeprazole, pantoprazole, esomeprazole, lansoprazole and rabeprazole (P < 0.05). The effect of rabeprazole on sPGI was less pronounced as compared with other PPIs, whereas esomeprazole achieved superior sPGI levels, with no overall statistically significant difference among the five groups (P > 0.05). However, a comparison within a single group of PPIs showed a statistical significance when the esomeprazole group was compared with the rabeprazole group (P = 0.007). sPGI levels are significantly influenced by antisecretory therapy, rising under PPI treatment. Moreover, a statistically significant difference in sPGI levels between the rabeprazole and esomeprazole groups has been demonstrated.

ABSTRACT

We aimed to improve symptoms by means of mesalazine in symptomatic colonic diverticular disease patients. One hundred seventy outpatients (98 M, 72 F; age, 67.1 years; range, 39-84 years) were assigned to four different schedules: rifaximin, 200 mg bid (Group R1: 39 pts), rifaximin, 400 mg bid (Group R2: 43 pts), mesalazine, 400 mg bid (Group M1: 40 pts), and mesalazine, 800 mg bid (Group M2: 48 pts), for 10 days per month. At baseline and after 3 months we recorded 11 clinical variables (upper/lower abdominal pain/discomfort, bloating, tenesmus, diarrhea, abdominal tenderness, fever, general illness, nausea, emesis, dysuria), scored from 0 = no symptoms to 3 = severe. The global symptomatic score was the sum of all symptom scores. After 3 months in all schedules but Group R1, 3 of the 11 symptoms improved (P < 0.03); the global score decreased in all groups but Group R1 (P < 0.0001). Mesalazine-treated patients had the lowest global score at 3 months (P < 0.001). Mesalazine is as effective as rifaximin (higher dosage schedule) for diminishing some symptoms, but it appears to be better than rifaximin for improving the global score in those patients.
