Background. Gastric neuroendocrine tumors (GI-NETs) are rare lesions, usually discovered incidentally during endoscopy. Based on their pathology, there are 4 types of GI-NETs. Type I are multiple small polypoid lesions with central ulceration located in the gastric body or the fundus, associated with atrophic gastritis usually noninvasive and very rarely metastatic. We report on a rare case of a gastric NET arising from the muscularis propria layer of the pyloric ring.
Case report. We present the case of a 65-year old woman with a history of alcoholic cirrhosis, investigated for melena. Upper endoscopy revealed a 30 mm submucosal pedunculated polypoid lesion located on the pylorus protruding in the duodenum, with normal overlying mucosa, fundic gastric atrophy and multiple small polyps at this level, with no active bleeding. CT scan did not reveal any distant metastases. An ultrasound endoscopy was performed, and a round hypoechoic heterogeneous solitary mass, evolving from the pyloric muscle was described. Considering a 30-mm tumor evolving from the gastric muscle layer in the absence of local invasion and with no distant metastases we decided against an endoscopical resection and we referred the patient to surgery. A laparoscopic wedge resection was performed. The pathology report described a 30/25 mm welldifferentiated neuroendocrine tumor invasive in the muscularis mucosa (pT3).
Conclusions. Usually, type I neuroendocrine tumors are located in the body or the fundus of the stomach without submucosal invasion. The interesting feature in our case was that the tumor originated from the pylorus, making it an atypical presentation for a neuroendocrine tumor.

Background and aims. Selective cannulation of the desired duct is a key element in ERCP procedures and an important step in the training of fellows. However, there is limited data about technical success and patient safety for ERCPs conducted in a training setting.We aimed to evaluate the impact of trainee involvement on the cannulation technique and procedure related outcomes at ERCP.
Materials and methods. We conducted an observational study of all ERCP conducted in an endoscopy unit with an on-going training program. Patient related data and procedure-related data (method of cannulation, time to cannulation, degree of trainee involvement, technical success and procedure-related adverse events) were collected using a standard form. The method of cannulation, time to cannulation and procedure-related adverse events were compared between ERCPs with trainee involvement and those without.
Results. 641 consecutive ERCPs were evaluated and 474 native papilla cases performed by 4 trainers and 3 trainees were included in the final analysis. Trainees were involved in 171 procedures (36.1%), achieving cannulation of the desired duct in 50.8% of the cases. Cannulation rates were similar in the trainee group compared to the control group (91.7% vs. 88.7%) and there was no increase in the rate of adverse events. However, cannulation time was significantly longer in the trainee group with a significant increase in the rate of precut use (32.1% vs. 23.4%, p < 0.001).
Conclusions. Trainee involvement resulted in longer cannulation times and increased use of precut sphincterotomy, but, was not associated with an increased risk of procedure related adverse events.

Background and aims. As already known, spondyloarthritis patients present a striking resemblance in intestinal inflammation with early Crohn’s disease. Moreover, the frequent use of nonsteroidal anti-inflammatory drugs is an important part of their treatment. Both conditions could lead to intestinal stenoses. Therefore we proposed to investigate the usefulness of the patency capsule test in patients with spondyloarthritis.
Material and methods. 64 consecutive patients (33 males; mean age 38 ± 11 years) that fulfilled the AMOR criteria for seronegative spondyloarthropathy (59.4% ankylosing spondylitis) lacking symptoms or signs of intestinal stenosis were enrolled and submitted to an AGILE™ capsule patency test followed by a video capsule endoscopy (PillCam SB2™), as part of a protocol investigating the presence of intestinal inflammatory lesions. After reviewing the VCE recordings, the Lewis score (of small bowel inflammatory involvement) was computed.
Results. In only 5 patients (7.8%) of the study group, the luminal patency test was negative. However, there was no retention of the videocapsule in any of the patients. From the 59 patients with a positive patency test, 3 patients presented single small bowel stenoses (two with ulcerated overlying inflamed mucosa, one cicatricial), all being traversed by the videocapsule along the length of the recording. None of the patients with a negative test had bowel stenoses. There was no correlation between the patency test and the Lewis score, the C reactive protein value, diagnosis of inflammatory bowel disease, or the family history of spondyloarthritis, psoriasis or inflammatory bowel disease.
Conclusion. The AGILE patency capsule does not seem to be a useful tool for all patients with spondyloarthritis prior to small bowel videocapsule endoscopy (ClinicalTrial.gov ID NCT 00768950).
