Video: Balloon Gastrostomy Tube in Stomach
The g-tube enters the abdomen from outside the body and goes directly into the stomach. The stomach is tented up from the CO2 insufflating the abdomen which allows space for the camera. The adherence of the stomach to the abdominal wall is what allows the gastrostomy to be changed without leaking into the peritoneal cavity.
