Surgical robots are being developed for the purpose of enabling endoscopic surgeries such as natural orifice transluminal endoscopic surgery (NOTES) as well as procedures which are receiving broader adoption in regional markets, such as endoscopic submucosal
The nodular, submucosal
, encapsulated lesion, which measured approximately 2 cm in its largest dimension, was removed completely using cold instruments.
2), making three submucosal

proventricular glands, consisting of secretory units and collecting tubules, occupied parts of the choristomal wall.
Most (77%) had a normal uterus; 15% had an intramural fibroid; 2% a submucosal

In addition, CD involves the full thickness of bowel wall; submucosal
inflammation is responsible for tissue destruction and penetration, leading to such complications as fibrosis, strictures, and fistulae.
A study that evaluated bacterial populations present in the submucosal
intestinal tissue of patients with Crohn's and controls provides evidence suggesting there may be "at least two distinct populations or biotypes within the Crohn's disease spectrum and the existence of a submucosal
microbiome in both health and disease," according to the investigators.
As the robotic arms are controlled like a doctor's hands intuitively and precisely using the joystick controller, MASTER would enable to support the accurate, safe performance of highly sophisticated surgery such as endoscopic submucosal
With gastric melanoma weight loss, abdominal pain and anemia are common presenting symptoms, with small bowel metastases, small bowel intussusception due to submucosal
lesions is the most common acute clinical presentation.
Lesions fall into 2 categories: superficial myofibromatosis with nodules confined to the subcutaneous and submucosal
stroma with occasional involvement of skeletal muscle or bone; and generalized myofibromatosis with visceral lesions.
The structure of the small intestine consists of a layer of cells, a mucosal lining, a connective tissue support (submucosa), and a fine submucosal
smooth muscle layer.
Intraepithelial hemorrhage of the esophagus is confined mainly within the epithelium, whereas acute necrotizing esophagitis shows widespread mucosal sloughing and necrosis of the residual mucosa, and extensive submucosal
