Laparoscopic transverse colectomy with ICG‐guided lymphadenectomy – A video vignette

Our Video S1 shows a robotic- assisted sigmoidectomy with partial ure-terectomy and reconstruction for ureteral stricture secondary to sigmoid diverticulitis. A 70- year- old woman presented with a history of recurrent episodes of diverticulitis. The preoperative CT scan showed a complicated sigmoid diverticulitis associated with left ureter stenosis, at the level of the left iliac vessel bifurcation, leading to hydrouret-eronephrosis (grade I). The procedure started with sigmoid release and drainage of a purulent collection between sigmoid and ileum. A medial-to- lateral dissection, division of the inferior mesenteric vein and splenic flexure takedown were performed. The fibrotic tissue, caused by chronic inflammation of recurrent diverticulitis, made the sigmoid and rectal mobilization from the left pelvic wall and the uterus more com - plex. Then the rectum was transected. The left ureter was mobilized up to the level of the left iliac artery bifurcation and the stenosis was identified. A left salpingectomy and appendicectomy were performed because of involvement by the inflammatory process. An attempt of double J catheter positioning failed; then a resection of the ureteral stricture was performed. The ureter was reconstructed with an end- to-end anastomosis with an absorbable interrupted suture. The procedure concluded with a conventional end- to- end colorectal anastomosis, ac-cording to the Knight– Griffen technique, reinforced with seroserosal absorbable interrupted stitches. A drain was left in place.
