Endoscopic ultrasound-guided fine-needle biopsy of small solid pancreatic lesions using a 22-gauge needle with side fenestration.

BACKGROUND: Early detection of small pancreatic cancer is important because expected survival is markedly better for tumors ≤ 2 cm. A new endoscopic ultrasound-(EUS) guided biopsy needle with side fenestration has been recently developed to enable fine-needle biopsy (FNB) under EUS guidance. The aim of this study was to evaluate the outcome of EUS-FNB using a 22-gauge ProCore needle in solid pancreatic lesions ≤ 2 cm, in terms of diagnostic accuracy and yield. METHODS: From January 2011 to December 2012, all consecutive EUS-guided tissue sampling of small pancreatic lesions (≤ 2 cm) were performed using 22-gauge ProCore needles; the data of these patients were analyzed retrospectively. RESULTS: Sixty-eight patients with a mean age of 65.7 years were included. The mean lesion size was 16.5 mm (range 5-20). None of the patients developed complications. On pathological examination, the tissue retrieved was judged adequate in 58 out of 68 cases (85.3 %) and the presence of a tissue core was recorded in 36 out of 68 cases (52.9 %). The overall sensitivity, specificity, positive predictive value, negative predictive value, and accuracy were 80, 100, 100, 40, and 82 %, respectively. CONCLUSION: Our results suggested that EUS-FNB of small pancreatic lesions using a 22-gauge ProCore needle is effective and safe, and supports our hypothesis that EUS-FNB is highly useful in establishing the nature of small pancreatic lesions.

Four-year follow-up of psychiatric and psychosomatic profile in patients with Inflammatory Bowel Disease (IBD).

Psychological characterization of patients affected by Inflammatory Bowel Disease (IBD) focuses on comorbidity with psychiatric disorders, somatization or alexithymia. Whereas IBD patients had higher risk of stable anxiety and depression for many years after the diagnosis of the disease, there is a lack of studies reporting a comprehensive psychosomatic assessment addressing factors of disease vulnerability, also in the long-term. The objective of this investigation is to fill this gap in the current literature. The aims were thus to assess: a) changes between baseline and a 4-year follow-up in psychiatric diagnoses (SCID), psychosomatic syndromes (DCPR), psychological well-being (PWB-I), lifestyle, gastrointestinal symptoms related to IBD and Irritable Bowel Syndrome (IBS)-like symptoms b) stability of psychiatric and psychosomatic syndromes at 4-year follow-up. A total of 111 IBD outpatients were enrolled; 59.5% of them participated at the follow-up. A comprehensive assessment, including both interviews and self-report questionnaires, was provided at baseline and follow-up. Results showed increased psychiatric diagnoses, physical activity, consumption of vegetables and IBS-like symptoms at follow-up. Additionally, whereas psychiatric diagnoses were no longer present and new psychopathological pictures ensued at follow-up, more than half of the sample maintained psychosomatic syndromes (particularly allostatic overload, type A behavior, demoralization) from baseline to follow-up. Long-term presence/persistence of such psychosocial burden indicates the need for integrating a comprehensive psychosomatic evaluation beyond traditional psychiatric nosography in IBD patients. Moreover, since psychosomatic syndromes represent vulnerability factors of diseases, further studies should target subgroups of patients presenting with persistent psychosomatic syndromes and worse course of the disease.

Preoperative diagnosis of a solid pseudopapillary tumour of the pancreas by Endoscopic Ultrasound Fine Needle Biopsy: A retrospective case series.

BACKGROUND: A solid pseudopapillary tumour of the pancreas (SPTP) is a rare neoplasm. AIM: We herein present five cases of SPTP diagnosed using endoscopic ultrasound (EUS) guided fine-needle biopsy (FNB) using a needle with side fenestration (ProCore-needle). METHODS: From January 2011 to June 2012 in five patients with SPTP tissue acquisition was carried out with a 19-gauge (4 patients) or a 22-gauge (one patient) needle. RESULTS: The mean age of the patients was 30.8 years, the mean lesion size was 49mm and the most common location was the tail of the pancreas (3 cases). When the samples were evaluated macroscopically, small core fragments were observed in all cases. A preoperative diagnosis of SPTP was made in all patients on the basis of the histocytological and characteristic immunophenotypic patterns and was confirmed at final surgical histology. CONCLUSIONS: In our experience, EUS-FNB is an effective and secure method for a preoperative diagnosis of SPTP.
