Air embolism is a rare complication of upper gastrointestinal endoscopy, but potentially catastrophic. It can be clinically irrelevant, or may lead to pulmonary or even systemic embolism. Air embolism occurs mainly when low-pressure vessels are in contact with high-pressure air. Fewer than ten cases after upper gastrointestinal endoscopy have been reported [1, 2]. A 48-year-old man with clinica...

Hyperplastic gastric polyps are incidentally diagnosed during upper gastrointestinal endoscopy. They are known to cause gastric outlet obstruction and chronic blood loss leading to iron deficiency anemia. However, hyperplastic gastric polyp presenting as acute severe upper gastrointestinal bleeding is very rare. To the best of our knowledge, there have been two cases of hyperplastic gastric pol...

Topical anaesthesia was also found to be unnecessary in sedated patients in a subsequent study'. However the mean (range) dose of midazolam given to patients in this study was 8 mg (4-10). Using a lower dose of midazolam (mean dose = 5.2 mg ± 0.5 (2SEM) ), lignocaine spr...
