Hirschsprung disease (HSCR) is a rare congenital intestinal disease characterized by the absence of ganglion cells in the distal rectum, extending for variable distances into the proximal intestine.The \"pull-through\" reconstruction procedure described in 1949 by Orvar Swenson involving the removal of the aganglionic bowel and creating an anastomosis between the normally innervated bowel and the anal canal, remains the standard surgical approach for HSCR today. However, as rectal dissection by laparotomy in infants is technically difficult and can result in high rates of complications, other pull-through techniques were developed and several techniques are still widely used today. In our institute, we developed the laparoscopic-assisted modified Soave with short muscular cuff anastomosis in July 2017, and achieved good therapeutic effects. However, there have some patients suffered soiling incidents in the short period post-surgery. Therefore, we developed the robot-assisted modified Soave with short muscular cuff anastomosis procedures to protect the vital nerve and blood vessels of the pelvis from injury, decrease the injury of the sphincter. this clinical trials was to compare the efficacy of robot-assisted and laparoscopic-assisted modified Soave with short muscular cuff anastomosis procedures for classical Hirschsprung disease (HSCR).
