To study the feasibility of specimen removing and dysfunctional loop ileostomy using previous lower abdominal incision for patients with rectal cancer.

The 22 cases of rectal cancer that received sphincter-saving surgery and dysfunctional loop ileostomy using previous lower abdominal incision treated in our hospital from Jan 2017 to Jun 2019 were analyzed, which was regard as observation group. The 40 cases which had used a new incision were selected as control group. The clinical data and complication with stoma and closure of stoma were collected and analyzed. The VAS score was used to compare the pain severity. The Karnofsky score was used to compare the functional status.

No significant difference was noted between the two groups in terms of operative time, blood loss, postoperative eating time, first leaked time of stoma bag, incidence of anastomotic leakage (t=2.539, 0.879, 0.866, 0.774, χ²=6.508; P>0.05). The scores of pain severity in the observation group were significantly lower than those in the control group at every time after the operation (t=5.695, 7.614, 6.677; P<0.05). The cases of using analgesic were also lower than the control group (χ²=5.213, P<0.05). There were no significant differences between the two groups in the incidence of complications related to stoma and stoma closure (P>0.05). The Karnofsky score was (82.7±5.6) in the observation group, which was significant higher than (78.4±5.2) in control group (t=2.906, P<0.05).

It is safe and feasible to do specimen removing and dysfunctional loop ileostomy using previous lower abdominal incision for patients with rectal cancer, which promote the recovery.
