Endoscopic ultrasonography can avoid unnecessary laparotomies in patients with pancreatic adenocarcinoma and undetected peritoneal carcinomatosis.

BACKGROUND/OBJECTIVE: To assess the relationship between the presence of ascites detected by endoscopic ultrasonography (EUS) and peritoneal carcinomatosis (PC) in patients with pancreatic adenocarcinoma. METHODS: Consecutive patients who underwent a EUS for preoperative staging of a pancreatic adenocarcinoma between 1998 and 2014 were retrospectively reviewed. The diagnosis of PC was confirmed by histopathology or peritoneal fluid cytology. The main outcome of the study was the relationship of ascites at EUS and PC in patients with pancreatic cancer. Secondarily, to evaluate the relationship between this finding and survival as well as the development of PC during follow-up. RESULTS: A total of 136 patients were included: 30 patients with local unresectable tumor or metastatic disease and 106 potentially-resectable candidates based on CT staging. EUS showed ascites in 27 (20%) patients, of whom 8 (29.6%) had PC. The sensitivity, specificity, PPV, NPV and accuracy of ascites by EUS in the detection of PC in this group of patients were 67%, 85%, 30%, 96% and 83%, respectively. Ascites detected by EUS was the only independent predictive factor of PC with an OR of 11 (CI 95%: 3-40). The detection of ascites by EUS was associated with a shorter survival (median survival time 7,3 months; range 0-60 vs 14.2 months; range 0-140) (p = 0.018) and earlier development of PC during follow-up (median 3.2 months, range 1.4-18.1 vs 12.7 months, range 5.4-54.8; p = 0.003). CONCLUSION: The finding of ascites at EUS in patients with pancreatic adenocarcinoma is highly associated with PC and a poor outcome.

Endoscopic ultrasound-guided fine needle aspiration is highly accurate for the diagnosis of perirectal recurrence of colorectal cancer.

BACKGROUND: Endoscopic ultrasound-guided fine needle aspiration is highly accurate for the diagnosis of malignancies surrounding the gastrointestinal tract. There is a lack of information on the usefulness of this technique in the diagnosis of colorectal cancer recurrence. OBJECTIVE: The purpose of this work was to investigate the performance characteristics of endoscopic ultrasound-guided fine needle aspiration for the cytologic diagnosis of perirectal recurrence of colorectal cancer. DESIGN: This was a retrospective study on the clinical and radiologic suspicion of perirectal recurrence of colorectal cancer. SETTINGS: The study was conducted at 4 tertiary hospitals. PATIENTS: Consecutive patients with suspicion of perirectal recurrence of colorectal cancer undergoing endoscopic ultrasound-guided fine needle aspiration between 2000 and 2013 were included in this study. INTERVENTIONS: The study intervention was endoscopic ultrasound-guided fine needle aspiration. MAIN OUTCOME MEASURES: Endoscopic ultrasound-guided fine needle aspiration performance characteristics and outcome (malignant or benign) were analyzed. The gold standard was cytologic results if malignancy or follow-up if benignity. RESULTS: A total of 58 patients were included (32 men; mean age, 64.2 ± 10.0 years [range, 44-88 years]). The location of the initial neoplasm was the rectum for 42 patients and the colon for 16 patients. Endoscopic ultrasound findings included a mass in the anastomosis (n = 8), perirectal fat (n = 23), lymph nodes (n = 20), or asymmetric thickness of the rectal wall (n = 6). Cytology showed malignancy in 38 patients (67%), benign features in 17 (30%), and was not evaluable in 2. Mean follow-up to confirm a benign outcome was 51.3 ± 30.3 months (range, 5.2-180.0 months). Final outcome was recurrence in 40 patients (69%) and benignity in 18 patients (31%). Performance characteristics of endoscopic ultrasound-guided fine needle aspiration were sensitivity (97%), specificity (100%), positive predictive value (100%), negative predictive value (94%), and accuracy (98%). In the intention to diagnose analysis, the corresponding values were 95%, 100%, 100%, 90%, and 96%. LIMITATIONS: This was a retrospective series with a limited number of patients. CONCLUSIONS: Endoscopic ultrasound-guided fine needle aspiration is a highly accurate tool for the cytologic diagnosis of perirectal recurrence in patients with previous colorectal cancer.

The real-world effectiveness of vedolizumab on intestinal and articular outcomes in inflammatory bowel diseases.

BACKGROUND: The effectiveness of vedolizumab in real-world practice is under evaluation, while its role in inflammatory bowel disease-associated spondyloarthritis is still unclear. AIMS: To report real-world data about the effectiveness of vedolizumab on intestinal and articular symptoms after 10 and 22 weeks of treatment. METHODS: Web-based data from the cohort of the Sicilian Network for Inflammatory Bowel Disease (SN-IBD) were extracted to perform a prospective multicentre observational study. RESULTS: 163 patients (84 with Crohn's disease and 79 with ulcerative colitis) were included. At week 10, a steroid-free remission was achieved in 71 patients (43.6%), while at week 22 a steroid-free remission was obtained in 40.8% of patients. A response on articular symptoms was reported after 10 weeks of treatment in 17 out of 43 (39.5%) patients with active spondyloarthritis at baseline, and in 10 out of 22 (45.4%) patients at week 22. The only factor associated with articular response was the coexistence of clinical benefit on intestinal symptoms (at week 10: OR 8.471, p = 0.05; at week 22: OR 5.600, p = 0.08). CONCLUSIONS: Vedolizumab showed good effectiveness after 10 and 22 weeks of treatment. A subset of patients reported improvement also on articular symptoms, probably as a consequence of the concomitant control of gut inflammation.

Quick, safe and effective repair of EUS-related duodenal perforation using over-the-scope clip system (with video).

Duodenal perforation is a rare but potentially life-threating complication of bilio-pancreatic endoscopic-ultrasound (EUS) examination. Here we report a case of 90 yeas-old patient underwent to EUS with curvilinear ecoendoscope and complicated by duodenal wall perforation. As reported in our case, Over-the-scope clipping system represents a quick, safe and effective approach in order close the leak and prevent further complication.
