Introduction
During endoscopic examination for pyloric obstruction, the site of obstruction can be directly visualized, which facilitates disease diagnosis and treatment. Patients must strictly fast from food and water for 6 to 8 hours before the endoscopy to prevent residual food particles or gastric fluid in the gastrointestinal tract from interfering with the examination results. Additionally, eating should be avoided for 2 to 3 hours after the endoscopy to prevent irritation and potential discomfort.
For patients with pyloric obstruction undergoing gastroscopy, strict fasting and abstaining from water for 6 to 8 hours are generally required. Additionally, food intake should be avoided for 2 to 3 hours after the gastroscopy to prevent irritation.
Gastroscopy is generally feasible for patients with pyloric obstruction and allows direct visualization of the obstructed site, aiding in disease diagnosis and treatment planning. However, prior to the procedure, it's essential to fast from both food and liquids for 6 to 8 hours to prevent residual food or gastric fluid in the gastrointestinal tract, which could interfere with the accuracy of the gastroscopic findings. Moreover, since gastroscopy is an invasive procedure, eating should be avoided for 2 to 3 hours afterward to minimize stimulation that might trigger adverse symptoms such as nausea or vomiting.
If a patient experiences severe pyloric obstruction or shows signs of increasing mass size, timely surgical intervention may be necessary. In the early postoperative period, a liquid diet is recommended to reduce gastrointestinal digestive load and promote recovery.
