 [ Symptoms ] using colostomy bag after hernia surgery after 7 days have not passed stools [ Disease ] in my opinion it is paralytic ileus it can usually take 1 3 weeks for the colon to heal after colostomy so stay with the current treatments iv feeding and wait if bowel movement returned then a nasogastric tube to be inserted and fluids should be given and gradually shifting to solid food but if no show of stool persisted then surgical interference is going to be necessary
