TACTICS OF TREATMENT OF PATIENTS WITH ULCERATIVE GASTRODUODENAL BLEEDING

Žurnal Grodnenskogo Gosudarstvennogo Medicinskogo Universiteta, 2018
Background. In spite of the achievements of modern gastroenterology the number of patients with ulcerative gastroduodenal bleeding do not tend to decrease. Lethality is still rather high – from 10 to 15%, which reaches 20-45% during the recurrence of

Endoscopic character identities for metaplectic groups [PDF]

arXiv, 2018
In this paper, we prove the conjectural endoscopic character identities for tempered representations of metaplectic group $Mp_{2n}$ based on the formalism of endoscopy theory by J. Adams, D. Renard and W.W. Li.

HemoSet: The First Blood Segmentation Dataset for Automation of Hemostasis Management [PDF]

arXiv
Hemorrhaging occurs in surgeries of all types, forcing surgeons to quickly adapt to the visual interference that results from blood rapidly filling the surgical field. Introducing automation into the crucial surgical task of hemostasis management would offload mental and physical tasks from the surgeon and surgical assistants while simultaneously ...

Risk factors and predictive nomograms for bedside emergency endoscopic treatment following endotracheal intubation in cirrhotic patients with esophagogastric variceal bleeding

Scientific Reports
Data on emergency endoscopic treatment following endotracheal intubation in patients with esophagogastric variceal bleeding (EGVB) remain limited. This retrospective study aimed to explore the efficacy and risk factors of bedside emergency endoscopic ...

Automatic Tip Detection of Surgical Instruments in Biportal Endoscopic Spine Surgery [PDF]

arXiv, 2019
Some endoscopic surgeries require a surgeon to hold the endoscope with one hand and the surgical instruments with the other hand to perform the actual surgery with correct vision. Recent technical advances in deep learning as well as in robotics can introduce robotics to these endoscopic surgeries.

PuraStat as secondary therapy for hemostasis in Mallory−Weiss syndrome with oral antithrombotic medication

DEN Open
Mallory−Weiss syndrome (MWS) is a common cause of gastroesophageal bleeding. Vomiting increases intra‐abdominal and intra‐esophageal pressures, causing hyperextension of the esophagogastric junction and laceration.

Forrest-type IIb increases the risk of rebleeding after endoscopic treatment in patients with Dieulafoy’s lesion of the upper gastrointestinal tract

Annals of Medicine
Background Dieulafoy’s lesion (DL) is a rare cause of nonvariceal upper gastrointestinal bleeding (NVUGIB) and represents a significant clinical challenge.

A CT-guided Control Framework of a Robotic Flexible Endoscope for the Diagnosis of the Maxillary Sinusitis [PDF]

arXiv
Flexible endoscopes are commonly adopted in narrow and confined anatomical cavities due to their higher reachability and dexterity. However, prolonged and unintuitive manipulation of these endoscopes leads to an increased workload on surgeons and risks of collision.

BrightVAE: Luminosity Enhancement in Underexposed Endoscopic Images [PDF]

arXiv
The enhancement of image luminosity is especially critical in endoscopic images. Underexposed endoscopic images often suffer from reduced contrast and uneven brightness, significantly impacting diagnostic accuracy and treatment planning. Internal body imaging is challenging due to uneven lighting and shadowy regions.
