“…The feasibility of surgery during severe GI GVH has been previously evaluated in 29 patients [4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19] in the literature including 16 children [4][5][6][7][8][9][10][11][12][13]. Most surgical procedures were performed because of digestive perforation [4,15,19], persistent digestive bleeding [5,12,15,17] or small bowel occlusion [4,6,[10][11][12][13]17]. Surgery was feasible despite GI GVHD but 8 out of the 29 patients reported so far died in the first month after surgery [7,9,[12][13][14][15]18].…”
