|March 1, 1986
Summary
Percutaneous gastrostomy (PG) and gastroenterostomy (PGE) are effective for alimentation and decompression. The coaxial trocar technique and needle puncture systems offer advantages for initial feeding tube placement.
Area of Science:
- Gastroenterology
- Minimally Invasive Procedures
Background:
- Percutaneous gastrostomy (PG) and gastroenterostomy (PGE) are established procedures.
- Indications include nutritional support and bowel decompression.
Purpose of the Study:
- To report initial experiences with PG and PGE in 40 patients.
- To evaluate different techniques for tube insertion.
Main Methods:
- Comparison of Seldinger technique (with air distension) and coaxial trocar technique.
- Evaluation of a preferred system using 18-gauge needle puncture for direct feeding tube insertion.
- Assessment of small bowel catheter positioning (PGE) versus gastrostomy alone.
Main Results:
- Small bowel catheter positioning (PGE) was more common (31 patients) than gastrostomy alone (8 patients).
- Coaxial trocar technique allowed initial insertion of larger, softer tubes, reducing exchanges.
- Five complications occurred, two major (catheter dislodgement).
Conclusions:
- Percutaneous gastrostomy and gastroenterostomy are feasible with various techniques.
- The coaxial trocar and needle puncture systems facilitate initial placement of feeding tubes.
- Careful patient selection and monitoring are crucial, especially for those with head and neck tumors.

01:28Esophageal Perforation-II: Clinical Manifestations and Management
Esophageal perforations manifest in various clinical forms, influenced by factors such as the perforation's cause and location (cervical, intrathoracic, or intra-abdominal), the extent of contamination, and potential injury to adjacent mediastinal structures. The timing between the perforation occurrence and treatment initiation also affects the clinical presentation.

01:29Endoscopic Procedures I: Esophagogastroduodenoscopy
An Esophagogastroduodenoscopy (EGD) is a diagnostic procedure in which an endoscopist uses a flexible, lighted endoscope to visualize the upper gastrointestinal (GI) tract. The procedure includes visualizing the oropharynx, esophagus, stomach, and the first part of the small intestine, the duodenum.
During an EGD, the endoscope can be used to:

01:26Enteral Nutrition I: Orogastric and Nasogastric Feeding
Enteral nutrition delivers nutrients directly to the stomach or small intestine through a tube. This method is appropriate for patients who cannot eat but still have a functioning digestive system. It is also beneficial for individuals with swallowing difficulties, anorexia, malabsorption, or those who have undergone gastrointestinal (GI) surgery.
Orogastric (OG) and nasogastric (NG) feeding are two standard methods used for enteral nutrition. Enteral nutrition is often preferred over...

01:15Enteral Nutrition II: Nasointestinal and Gastrostomy Feeding
Enteral nutrition encompasses various methods of delivering nutrition directly to the gastrointestinal (GI) tract, bypassing traditional oral intake. It is particularly beneficial for patients who cannot eat by mouth but have a functioning digestive system. Key methods include nasointestinal feeding, gastrostomy, and jejunostomy, each suited to different clinical scenarios based on the patient's needs and condition.
