B-suture Ileostomy in Clinical Practice: a Retrospective, Single-center, Propensity Score-matched Study

Type B suture stoma group：2-0 stitched sutures were placed in the center of the incision, from the anterior rectus sheath on the left side of the incision → the posterior rectus sheath on the left side of the incision → through the avascular area below the vascular arch at the mesenteric border of the ileum to the contralateral side → the posterior rectus sheath on the right side of the incision → the anterior rectus sheath on the right side of the incision→ the posterior rectus sheath on the right side of the incision → through the avascular area below the vascular arch at the mesenteric border of the ileum to the contralateral side → the posterior rectus sheath on the left side of the incision →the anterior rectus sheath on the left side of the incision sutures were sewn through in the sequence, tightened and knotted .

Then take the right lower abdominal incision to cut a circular incision of 3 cm in diameter, round excision of subcutaneous fat, cross incision of rectus sheath and peritoneum, enter the abdomen, raise the marked ileum out of the body, interrupt suture of ileum with peritoneum and posterior sheath of rectus abdominis for one week, then interrupt suture of ileum with anterior sheath of rectus abdominis for one week, transverse incision of 2 cm in diameter, interrupted with 3-0 absorbable thread, The ileocecal incision and the skin of the right lower abdominal circular incision were sutured for one week to complete the double-lumen stoma at the end of the ileum.
