Infantile intussusception surgery is major surgery. Because infant intussusception surgery is open surgery, general anesthesia and gastrointestinal decompression are required before surgery. Although the procedure is relatively simple and the operation time is short, it is major surgery for infants because of their low surgical tolerance. For infants with unsuccessful non-surgical repositioning, or infants with suspected intestinal necrosis or recurrent intussusception, the abdomen needs to be opened to visualize the intussusception mass and check for intestinal necrosis. If the intussusception has not resulted in intestinal necrosis, repositioning of the intussusception along the colonic frame is performed by compression. After repositioning, the bowel is carefully examined for necrosis, breakage, and massive bleeding. For children who cannot be repositioned and have intestinal necrosis, appropriate resection anastomosis of the intestinal segment is required. After the operation of infantile intussusception, light diet should be taken, pay attention to the amount of food each time, otherwise it will aggravate the burden of the stomach and intestines. And pay attention to keep the abdomen warm.
