Superficial neoplastic lesions of the digestive tract are usually asymptomatic, and often represent incidental findings on endoscopy. The Paris Classification was developed for the systematic evaluation of superficial lesions of the oesophagus, stomach and colon. The significance of this classification in clinical practice is that it allows the depth of invasion to be estimated. Read More

Differentiation of B cells is a stringently controlled multi-step process, which is still incompletely understood. Here we identify and characterize a rare population of human B cells, which surprisingly carry CD8AB on their surface. Existence of such cells was demonstrated both in tonsils and in human apheresis material. Read More

Background: Endoscopic submucosal dissection (ESD) is a complex endoscopic procedure, with high rates of adverse events and technical difficulties. To overcome that problem, many training centers published the importance of animal models for skill acquirement in ESD. However, no study has used the submucosal dissection depth (DSUB) as a parameter to evaluate the learning curve in ESD, which might be a relevant factor since an optimal resection plane is important to achieve a curative resection and avoid intraoperative complications.

Purpose: We investigated the effects of alterations in the biological markers p14, p53, p21, and p16 in relation to tumour cell proliferation, T-category, N- category, lymphovascular invasion, and the ability to predict prognosis in patients with muscle-invasive bladder cancer (MIBC) treated with cystectomy and, if applicable, chemotherapy.
Materials And Methods: We prospectively studied patients with urinary bladder cancer pathological stage pT1 to pT4 treated with cystectomy, pelvic lymph node dissection and postoperative chemotherapy. Tissue microarrays from paraffin-embedded cystectomy tumour samples were examined for expression of immunostaining of p14, p53, p21, p16 and Ki-67 in relation to other clinical and pathological factors as well as cancer-specific survival.

Background: The incidence of biliary lithiasis is increased after bariatric surgery due to rapid weight loss . Trans-oral endoscopic management in cases of common bile duct gallstone complication is not possible in patients with Roux-en-Y gastric bypass (RYGB) due to the modified anatomy. Access to the biliary tree after RYGB with a classical direct surgical approach of common bile duct and choledocoscopy can be used, but may be complicated in situations of acute cholangitis because of the fragility of common duct, or in cases of previous cholecystectomy.

Objectives: The principal objective of this pooled analysis was to investigate various patient and lesion characteristics on late lumen loss (LLL) after drug-coated balloon (DCB) angioplasty.
Background: Four randomized controlled trials (THUNDER, FEMPAC, PACIFIER, CONSEQUENT) were pooled to investigate the influence of various patient and lesion characteristics on DCB angioplasty and on plain old balloon angioplasty (POBA) in patients with femoropopliteal artery disease.
Methods: Angiographic data from 355 patients were pooled to assess the impact of patient (demographics, cardiovascular risk factors, cardiovascular co-morbidities, Rutherford stages) and lesion-/procedure-related (location, occlusion, length, restenosis, calcification, subintimal crossing, post-dilatation, dissection, stenting) characteristics on LLL.

Gastric cancers (GC) after eradication are difficult to diagnose even by magnifying narrow-band imaging (NBI) or blue laser imaging (BLI) endoscopy. Little is known with regard to non-magnifying (NM)-NBI/BLI for early GC so we examined the efficacy of NM-NBI/BLI for early GC diagnosis. We retrospectively analyzed the images of 29 small (≤ 1 cm) intramucosal GC that had been treated with endoscopic submucosal dissection and 137 benign depressed lesions (BDLs). Read More

Background: Successful radiosurgery for intracranial arteriovenous malformations (AVMs) requires accurate delineation of the nidus in 3D. Exact targeting and precise equipment is needed to achieve obliteration of the nidus while minimizing toxicity to the surrounding brain. In some micro-AVMs and poorly visible AVMs we have used cone beam CT angiography (CBCTA) with selective and super-selective angiography where a micro-catheter is advanced into the feeding arteries- to assist with nidus definition for CyberKnife radiosurgery planning.
