Safety and Feasibility of Umbilical Diverting Loop Ileostomy for Patients with Rectal Tumor

Fashioning an ileostomy in the umbilicus and combining the trauma from extraction of colorectum with that from ileostomy should be less invasive and lead to improved cosmetic outcomes. However, there are only a few reports regarding umbilical ileostomy.

We retrospectively collected data for 121 consecutive patients with rectal tumor who underwent elective laparoscopic rectal resection with diverting loop ileostomy between 2010 and 2015 at Osaka University Hospital, Japan. The safety and feasibility of umbilical diverting loop ileostomy and its influence on stoma care were investigated.

A total of 83 patients were included in this study; of these, 30 underwent umbilical diverting loop ileostomy and 53 underwent conventional diverting loop ileostomy, which was created in the right lower quadrant of the abdomen. The umbilical and conventional groups showed similar rates of postoperative and stoma-related complications (26.7 vs. 32.1%, p = 0.804 and 3.3 vs. 3.8%, p = 1.000, respectively). Level of parastomal dermatitis was evaluated by DET score at three time points (stoma self-management establishment, first outpatient review post-discharge, and just before stoma closure). DET scores at any time points did not differ significantly between the two groups.

Umbilical diverting loop ileostomy is comparable to conventional ileostomy with regard to safety and feasibility. Our methods for umbilical ileostomy using the umbilical skin flap were less invasive and did not have a negative impact on stoma care and parastomal dermatitis. Umbilical ileostomy may be a promising alternative to conventional ileostomy in selected cases.
