Tumore cistico pancreatico trattato mediante splenopancreasectomia distale con riscontro occasionale di neoplasia neuroendocrina
INTRODUCTION: Cystic and neuroendocrine pancreatic neoplasms are quite rare tumors which diagnosis is often difficult due to their non specific symptomatology and limited diagnostic accuracy of conventional diagnostic instruments. Their treatment is still controversial.
CASE REPORT: A young woman is admitted with abdominal pain and dyspepsia. Instrumental diagnosis reveals a cystic pancreatic lesion which seems to be malignant as CEA of pancreatic liquid is increased. The patient undergoes distal spleno-pancreatectomy and postoperative histological examination found IPMN associated with MCN and furthermore there was occasional diagnosis of a small neuroendocrine tumor in the pancreatic tail.
DISCUSSION: A correct diagnostic approach is indispensable for a correct therapeutic approach. Radical surgical treatment is indicated in all cases of main- and branch duct IPMN and in case of MCN with signs of malignant transformation. Surgical treatment is also the gold standard for pancreatic neuroendocrine tumors if they are singular and in M0 stage.
CONCLUSIONS: In case of cystic and neuroendocrine neoplasms of the pancreas the preoperative diagnostic approach is often not enough to obtain a definite diagnosis. Review of literature and this case report show that a definite diagnosis can only be done after postoperative histological examination. Recent prospective studies suggest the possibility for a follow up instead of surgical treatment for some neuroendocrine tumors
Endoscopic ultrasound-guided drainage of pancreatic collections with dedicated metal stents: A nationwide, multicenter, propensity score-matched comparison
Background: The new dedicated stents for endoscopic ultrasound (EUS)-guided transluminal drainage of peri‐pancreatic fluid collections (PFCs) demonstrated optimal efficacy and safety profiles. Aims: This study aimed to evaluate the safety, technical and clinical success, and recurrence rate of PFCs drained with Lumen Apposing Metal Stent (LAMS) or Bi-Flanged Metal Stent (BFMS). Methods: Data from a multicenter series of PFCs treated with LAMS or BFMS at 30 Italian centers during a 5-year period were retrieved. The rate of adverse events (AEs), technical success, clinical success, PFC recurrence were evaluated. To overcome biases, a 1-to-1 match was created using propensity score analysis. Results: Out of 476 patients, 386 were treated with LAMS and 90 with BFMS, with a median follow-up of 290 days (95% CI 244 to 361). Using propensity score matching, 84 patients were assigned to each group. The incidence of AEs did not differ between the two stents (13.1% versus 15.5%, p = 0.29), mainly bleeding or recurrence rate (4.7% versus 3.5%, p = 1). Technical and clinical success in the BFMS and LAMS groups were 92% versus 95% (p = 0.36) and 91% versus 94% (p = 0.64), respectively. Conclusion: Our study demonstrates that LAMS and BFMS have comparable safety profiles with similar technical and clinical success rates for EUS-guided PFC drainage
Informed Consent for Endoscopic Biliary Drainage: Time for a New Paradigm
Endoscopic retrograde cholangiopancreatography (ERCP) is considered as the first option in the management of malignant biliary obstruction. In case of ERCP failure, percutaneous transhepatic biliary drainage (PTBD) has been conventionally considered as the preferred rescue strategy. However, the use of endoscopic ultrasound (EUS) for biliary drainage (EUS-BD) has proved similarly high rates of technical success, when compared to PTBD. As a matter of fact, biliary drainage is maybe the most evident paradigm of the increasing interconnection between ERCP and EUS, and obtaining an adequate informed consent (IC) is an emerging issue. The aim of this commentary is to discuss the reciprocal roles of ERCP and EUS for malignant biliary obstruction, in order to provide a guide to help in developing an appropriate informed consent reflecting the new biliopancreatic paradigm
Pretreatment antibiotic resistance in <i> Helicobacter pylori</i> infection: eesults of three randomized controlled studies
Background.
Although combinations of antibiotics and
antisecretory drugs are useful for treatment of
Helicobacter pylori infection, treatment failure is common.
The aim of this study was to evaluate the relation between
pretreatment antibiotic resistance and outcome
by using six different treatment regimens for
H. pylori
infection.
Patients and Methods.
Three hundred sixty-nine consecutive
H. pylori–
infected patients with dyspeptic
symptoms were enrolled in three consecutive randomized,
controlled, single-center clinical trials: trial A, 128
patients; trial B, 125 patients; trial C, 116 patients.
Treatments consisted of (A) a 15-day course of dual
therapy (omeprazole, 20 mg bid, and amoxicillin, 1 gm
bid, or clarithromycin, 500 mg tid) (OA vs OC); (B) a
7-day triple therapy of omeprazole, 20 mg bid, plus
metronidazole, 500 mg bid, and amoxicillin, 1,000 mg
bid, or clarithromycin, 500 mg tid (OMA vs OMC); or
(C) omeprazole, 20 mg bid, plus metronidazole, 500 mg
bid, plus tetracycline, 500 mg qid, or doxycycline, 100
mg tid (OMT vs OMD). Diagnostic endoscopy was
made in all patients before and 5 to 6 weeks after therapy.
Six biopsies were taken from each patient for histology,
rapid urease test, and
H. pylori
culture; antibiotic
susceptibility testing was performed using the
E-test method.
Results.
Overall cure rates were poor for both dual
therapies OA and OC (38% and 37%, respectively) and
for triple therapies OMA, OMC, and OMD (57%,
55%, and 58%, respectively). The OMT combination
was successful in 91% (95% confidence interval [CI],
80.4%–97%). Metronidazole resistance was present in
29.7% (95% CI, 24%–35%), amoxicillin resistance
was present in 26% (95% CI, 21%–32%), clarithromycin
resistance was present in 23.1% (95% CI, 18%–
29%), tetracycline resistance was present in 14% (95%
CI, 10%–20%), and doxycycline resistance was present
in 33.3% (95% CI, 21%–47%). Antibiotic resistance
markedly reduced the cure rates and accounted for
most of the poor results with the triple therapies: 89%
versus 23%; 77% versus 26%; 100% versus 60%; and
67% versus 23% for OMC, OMA, OMT, and OMD,
respectively. OMT appeared to be the best because of
the high success rate with metronidazole-resistant
H.pylori (71%) and in low-level tetracycline resistance.
Conclusions.
Pretreatment antibiotic-resistant
H. pylori can, in part, explain the low cure rate of the infection and the variability in outcome in reported trial

Clinical and epidemiological features of ulcerative colitis patients in Sardinia, Italy: Results from a multicenter study
BACKGROUND There are little data on the epidemiological and clinical features of adult patients with ulcerative colitis (UC) in the different Italian regions, mainly derived from the absence of a national registry. This prevents correct interpretation of the disease burden. AIM To assess the main clinical and epidemiological features of adult patients diagnosed with UC in Sardinia, Italy. METHODS We performed a multicenter, observational, cross-sectional study that included adult patients with UC enrolled in seven gastroenterology unit centers in Sardinia. Data were obtained from the patients' medical records and from a questionnaire administered at the inclusion visit. RESULTS Four hundred and forty-two patients with UC were included. The median age at diagnosis was 39 years (interquartile range 28-48). After a median disease duration of 10 years, 53 patients experienced proximal extension of proctitis or left-sided colitis. Seventy-five patients developed extraintestinal manifestations. Nineteen patients (4.3%) developed cancer: two with colorectal cancer and seventeen with extracolonic cancers. Mesalazine (5-ASA) remains the mainstay of treatment for UC. Overall, 95 patients (21.5%) were treated with one or more biologic agents, whereas 15 patients (3.4%) underwent surgery, mostly colectomy. CONCLUSION Our results provide important insights into the clinical and epidemiological features of patients with UC, and while waiting for a national Italian registry, present eligible data on the UC population in Sardinia
Digital single-operator cholangioscopy in diagnostic and therapeutic bilio-pancreatic diseases: A prospective, multicenter study
Background and aim: Digital single-operator cholangioscopy (D-SOC) is an endoscopic procedure that is increasingly used for the management of bilio-pancreatic diseases. We aimed to investigate the efficacy and safety of D-SOC for diagnostic and therapeutic indications. Methods: This is a multicenter, prospective study(January 2016-June 2019) across eighteen tertiary centers. The primary outcome was procedural success of D-SOC. Secondary outcomes were: D-SOC visual assessment and diagnostic yield of SpyBite biopsy in cases of biliary strictures, stone clearance rate in cases of difficult biliary stones, rate of adverse events(AEs) for all indications. Results: D-SOC was performed in 369 patients (201(54,5%) diagnostic and 168(45,5%)therapeutic). Overall, procedural success rate was achieved in 360(97,6%) patients. The sensitivity, specificity, PPV, NPV and accuracy in biliary strictures were: 88,5%, 77,3%, 83,3%, 84,1% and 83,6% for D-SOC visual impression; 80,2%, 92,6%, 95,1%, 72,5% and 84,7% for the SpyBite biopsy, respectively. For difficult biliary stones, complete duct clearance was obtained in 92,1% patients (82,1% in a single session). Overall, AEs occurred in 37(10%) cases.The grade of AEs was mild or moderate for all cases, except one which was fatal. Conclusion: D-SOC is effective for diagnostic and therapeutic indications.Most of the AEs were minor and managed conservatively, even though a fatal event has happened that is not negligible and should be considered before using D-SOC
