The gastrointestinal endoscopy in this study refers to conventional gastroscopy and wireless capsule endoscopy (WCE). Both of these techniques produce a large number of images in each diagnosis. The lesion detection done by hand from the images above is time consuming and inaccurate. This study designed a new computer-aided method to detect lesion images. We initially designed an algorithm named joint diagonalisation principal component analysis (JDPCA), in which there are no approximation, iteration or inverting procedures...

Testicular germ cell tumors, though rare (1%), represent the most common neoplasm among young men. Gastrointestinal involvement from these malignancies usually presents as bowel obstruction and digestive bleeding, but their frequency is low (5%). The patterns of this involvement are: infiltration from affected retroperitoneal lymph nodes or, less frequently, by peritoneal seeding and direct hematogenous spread. Particularly, infiltration of duodenum is also rare, though its real frequency is not well defined...

INTRODUCTION: Patients with signs of acute bleeding into the gastrointestinal tract are hospitalized at intensive care units of surgical departments for organizational reasons. There is a growing proportion of those treated with various forms of antithrombotic therapy. From the onset of endoscopic methods of haemostasis, mortality is low and surgical treatment of these patients is rarely required. Their treatment takes up a lot of human and financial resources. The question remains, whether it would be possible to stop the volume growth or even reduce the number of these patients...

BACKGROUND: Bacteria affect oral health, but few studies have systematically examined the role of bacterial communities in oral diseases. We examined this relationship in a large population-based Chinese cancer screening cohort. METHODS: Human Oral Microbe Identification Microarrays were used to test for the presence of 272 human oral bacterial species (97 genera) in upper digestive tract (UDT) samples collected from 659 participants. Oral health was assessed using US NHANES (National Health and Nutrition Examination Survey) protocols...

AIM: Stent migration due to peristalsis of the colon is one of the unresolved complications of colonic self-expandable metallic stent (SEMS) placement. Axial force (AF), a recovery force of the stent to a straight position after bending, has been considered a factor influencing the conformability of the digestive tract. An uncovered SEMS (Niti-S Enteral Colonic Uncovered Stent, D-type; Taewoong, Inc., Gimpo, South Korea) with improved conformability is considered to decrease migration...

BACKGROUND: Multiple angiomatosis is a rare disease with angiomatous formations in multiple organs and tissues and associated with a risk of fatal bleeding. CASE DESCRIPTION: In this patient, the bones, pleural and peritoneal cavities and digestive tract were involved. The patient had long-term been administered zoledronate that provided relief from bone pain as early as after the second dose. The effect of antiangiogenics was evaluated on CT and MRI. Since angiomatous proliferation is associated with chronic disseminated intravascular coagulation (DIC) and anaemisation, blood count and fibrinogen as well as D-dimer and soluble fibrin monomer concentrations are also used to assess treatment response...

BACKGROUND: Upper gastrointestinal bleeding is a frequent cause for emergency hospital admission. Most severity scores include in their computation the endoscopic findings. The Glasgow-Blatchford score is a validated score that is easy to calculate based on simple clinical and biological variables that can identify patients with a low or a high risk of needing a therapeutic (interventional endoscopy, surgery and/ or transfusions). AIM: To validate retrospectively the Glasgow-Blatchford Score (GBS)...

UNLABELLED: Gastrointestinal stromal tumours (GISTs) represent the most common non-epithelial tumour of the digestive tract. Laparoscopic approach may be considered ideal for the resection of these tumours. Their particular biological behaviour allows for a curative resection even without large resection margins and extensive lymphadenectomies. METHOD: Over a period of five years, eight patients benefited from laparoscopic resections (six patients with primary gastric GIST and two patients with small bowel GIST)...
