Percutaneous Endoscopic Gastrostomy (PEG)-Better Way of Nutrition Support

Percutaneous endoscopic gastrostomy (PEG) is an endoscopic medical procedure in which a tube (PEG tube) is passed into a patient's stomach through the abdominal wall, most commonly to provide a means of feeding when oral intake is not adequate (for example, because of dysphagia or sedation). This provides enteral nutrition (making use of the natural digestion process of the gastrointestinal tract) despite bypassing the mouth; enteral nutrition is generally preferable to parenteral nutrition (which is only used when the GI tract must be avoided). The PEG procedure is an alternative to open surgical gastrostomy insertion, and does not require a general anesthetic; mild sedation is typically used. PEG tubes may also be extended into the small intestine by passing a jejunal extension tube (PEG-J tube) through the PEG tube and into the jejunum via the pylorus.

Gastrointestinal endoscopic mucosal resection (EMR) is a procedure to remove early-stage cancer and precancerous growths from the lining of the digestive tract.

Endoscopic Mucosal Resection (EMR)

Endoscopic mucosal resection is performed with a long, narrow tube equipped with a light and video camera. During EMR of the upper digestive tract, the doctor passes this tube (endoscope) down your throat into your esophagus, stomach or upper part of the small intestine (duodenum). To reach the colon, the doctor guides the tube up through the anus. The doctor then inserts instruments through the tube to perform the procedure.

Colonoscopy in Elderly

With increasing age, the incidence of both benign and malignant gastrointestinal (GI) disease rises. Endoscopic procedures are commonly performed in elderly and very elderly patients (>70 years old) to diagnose and treat GI disorders. There are a number of issues to contemplate when considering performing an endoscopic procedure in an elderly patient, including the anticipated benefits of endoscopy as well as the increased risks associated with procedural sedation and some endoscopic procedures. We have done more than 1000 cases of colonoscopy for patients more than 70 years old.


Major Diseases of Treatment Include:

  •  Gastric cancer

  •  Colorectal cancer

  •  Liver cancer

  •  Esophagus cancer

  •  Gall bladder cancer

  •  Pancreatic cancer

  •  IBD

  •  GI bleeding

  •  Ischemic bowel disease

  •  Hepatitis, fibrosis, cirrhosis and liver failure


The department has put an emphasis on international communication since the foundation. Up to now, there are 3 persons who have been sent out abroad with the support from China Scholarship Council (CSC) and Jiangsu Provincial Committee of Health and Family Planning. In addition, more than 10 persons have been invited to give oral or poster presentation in a series of international conferences.

Besides, there are still some cooperative projects between the department and international institutions, such as UT MD Anderson Cancer Center and Juntendo University.
