A nasogastric tube mistakenly sutured to the anastomotic site is a rar
e surgical error during gastrointestinal operation. When it does happe
n, proper management will prevent subsequent complications. If resista
nce is experienced when pulling the nasogastric tube after gastrointes
tinal surgery, it should never be pulled more forcefully. The endoscop
e should be introduced to document the etiology and to provide treatme
nt after 2 weeks postoperation based on the wound healing process and
strength of suture materials.
