Robotic-assisted proctosigmoidectomy for Hirschsprung’s disease: A multicenter prospective study

Figure 5 Comparison of two minimally invasive approaches and dissection length measurement of robotic-assisted proctosigmoidectomy. A: The transanal Soave anastomosis procedure is performed by making a circular incision 0.5-1 cm from the dentate line and dividing the mucosa upward by 0.2-0.4 cm; B: The length of pelvic dissection was 5.5 cm and the length of transanal dissection was 0.3 cm of robotic-assisted proctosigmoidectomy; C: The length of endorectal dissection and transanal dissection in the laparoscopic approach; D: The length of endorectal dissection and transanal dissection in the robotic approach.
