Surgery is not necessary when a coin enters the small intestine. If the coin is small, it can be excreted in 1-2 days with feces, so surgery is not necessary. However, if the coin that enters the small intestine is large and cannot be expelled, it may lead to narrowing and obstruction of the small intestine, which may result in intestinal necrosis and intestinal perforation, and then surgical intervention is required. Basically, the risk of small bowel surgery is not significant, and the localized lesions of the small bowel can be removed laparoscopically. However, the risk of coin entry surgery in the small intestine also depends on the degree of inflammation caused by the coin after causing stenosis and obstruction in the local small intestine. Although the removal of coins through small bowel surgery is basically a simple procedure, the risk is not significant. However, if the coin carries bacteria on its surface, it can easily cause bacterial infection in the intestinal lumen. If the intestinal wall becomes narrowed and obstructed, necrosis and perforation are more likely to occur. If a phase I suture is performed, it is enough to remove the coin and sew it back on. However, if the surgery is not timely, inflammation and hyperplasia may occur, and segmental dissection is needed, and then the extent of inflammation needs to be considered, and whether fistulas and sinus tracts are easily formed, so a phase II surgery is needed, i.e., a phase I fistula is placed first, and then a phase II is retracted. In conclusion, there is a risk of coins entering the small intestine, but the danger of performing small bowel surgery is not significant. In addition, the length of time the coin remains in the small intestine is important for the timing of performing the surgery. Usually after 24-48 hours, if the coin is not expelled, the timing of surgery needs to be decided by imaging X-ray or CT local image performance, and then combined with inflammatory response to minimize surgical complications, as well as perioperative risks.
