ENDOSCOPY IN GASTROINTESTINAL BLEEDING
The results of early scrutiny in patients with upper-gastrointestinal-tract hurt, spoken the gi service of an oversized general hospital, were reviewed. 111 endoscopies were allotted during a hundred and 6 patients. A supply of active or recent hurt was known in fifty six (50•3%) instances; in thirty eighth of those a further non-bleeding lesion was found. Success in characteristic the positioning of hurt fell quickly from seventy eight at intervals twenty four hours of admission to thirty second when forty eight hours. Patients with hæmatemesis were admitted to hospital earlier and had scrutiny a lot of quickly than patients with melæna alone; this in all probability accounted for the upper scrutiny success-rate during this cluster. 
Gastric reduction endoscopy
A technique is delineate for reducing the abdomen cavity endoscopically, from among the abdomen or, within the different, from among the bodily cavity via a wall of the digestive tube. This new approach for reducing stomachal capability uses a versatile medical instrument and a specially tailored ligating loop that’s secured at spaced locations regarding an inner edge of the abdomen. when attachment, the loop is constricted to connect the associated stomachal wall parts to cut back the food receiving cavity outlined at the bottom of the passage. The ligating loop is ideally a blunder knotted loop. 
Despite widespread use of multiphoton microscopy, development of endoscopes for nonlinear optical imaging has been stymied by the degradation of ultrashort excitation pulses that happens inside fiber as a results of the combined effects of group-velocity dispersion and self-phase modulation. we tend to introduce microendoscopes (350–1000 µm in diameter) supported gradient-index microlenses that effectively eliminate self-phase modulation inside the medical instrument. Laser-scanning multiphoton visible radiation scrutiny exhibits micrometer-scale resolution. we tend to used multiphoton endoscopes to image fluorescently tagged neurons and dendrites. 
Safety profile of sedative endoscopy including cognitive performance in liver cirrhosis: A double-blind randomized controlled trial
The indiscriminate use of sedative medication throughout examination will create multiple risks as well as psychological feature impairment in advanced liver liver disease. However, the information are scarce concerning that sedative medication are safest in these populations. The aim of this study was to judge the security profiles as well as psychological feature performance among Versed, propofol, and combination medical aid in advanced cirrhotic patients. This double-blind irregular controlled study enclosed sixty consecutive advanced cirrhotic patients United Nations agency underwent higher duct examination. The Stroop application was accustomed screen for psychological feature impairment. 
Drug-Induced Sleep Endoscopy and Our Clınıcal Experıences
Aim: This study aims to judge the results of drug-induced sleep endoscopy(DISE) patients.
Study Design: Retrospective study.
Place and length of Study: Department of otorhinolaryngology between January 2018 and March 2018.
Methodology: a complete of thirty eight patients (32 males,6 females; mean age forty two.0±9.11 years; vary twenty three to 67) Demographic knowledge, apnea-hypopnea indexes and also the level of obstruction of the patients were mentioned within the light-weight of literature.
Results: Most patients were with gentle preventative apnea (42.1%).Most of the patients had a structure obstruction(60.5%). most typically seen level of obstruction was tongue. once the patient’s age, sex, BMI(body mass index), AHI(apnea-hypopnea index) and level of obstruction was compared there wasn’t a statistically vital relation. (p>0.05).
Conclusion: There was no distinction between the amount of obstruction, body mass index and apnea-hypopnea index values. giant analysis studies area unit required to research the worth of drug-induced sleep examination.
