Application value of one-stitch prophylactic ileostomy in late ileostomy closure: a prospective analysis / 中华消化外科杂志

ABSTRACT

Objective:To investigate the application value of one-stitch prophylactic ileostomy in late ileostomy closure.Methods:The prospective randomized control study was conducted. The clinicopathological data of 141 patients with rectal cancer who underwent low anterior resection combined with prophylactic ileostomy in the Affiliated Tumor Hospital of Zhengzhou University from January 2016 to July 2020 were selected. There were 127 patients being selected after excluding 14 cases who did not undergo ileostomy closure. Patients undergoing one-stitch prophylactic ileostomy were divided into observation group, and patients undergoing traditional ileostomy were divided into control group. Observation indicators: (1) grouping situations of the enrolled patients; (2) surgical situations of ileostomy closure; (3) postoperative situations; (4) follow-up. Follow-up was conducted using outpatient examination and telephone interview once a month after low anterior resection combined with prophylactic ileostomy to detect complication and death of patients. The end point was at 3 months after ileostomy closure. The follow-up was up to July 2020. Measurement data with normal distribution were represented as Mean±SD, and comparison between groups was conducted using the independent sample t test. Measurement data with skewed distribution were represented as M( P25, P75) or M (range), and comparison between groups was conducted using the Mann-Whitney U test. Count data were described as absolute numbers, and comparison between groups was conducted using the chi-square test. Comparison of ordinal data between groups was conducted using the Mann-Whitney U test. Results:(1) Grouping situations of the enrolled patients: a total of 127 patients were selected for eligibility, aged from 31 to 83 years, with a median age of 64 years. Of 127 patients, there were 66 cases in observation group and 61 cases in control group. (2) Surgical situations of ileostomy closure: all patients from the two groups underwent ileostomy closure successfully. The incision length, operation time, volume of intraoperative blood loss, cases with abdominal adhesion degree as slight adhesion or obvious adhesion were 4.25 cm(4.00 cm, 5.00 cm), 48.00 minutes(33.75 minutes, 58.00 minutes), 30 mL(20 mL, 50 mL), 34, 32 of the observation group, versus 7.50 cm(7.00 cm, 8.50 cm), 70.00 minutes(57.00 minutes, 80.00 minutes), 30 mL(30 mL, 50 mL), 13, 48 of the control group, showing significant differences between the two groups ( Z=-9.549, -6.133, -2.758, χ2=12.405, P<0.05). (3) Postoperative situations: cases with incision infection of the observation group and the control group were 5 and 13, respectively, showing a significant difference between the two groups ( χ2=4.917, P<0.05). (4) Follow-up: all the 127 patients were followed up for 6-21 months, with a median follow-up time of 10 months. During the follow-up, 3 cases of the control group had postoperative incisional hernia and were cured after conservative treatment. None of patient had anastomotic leakage related complications or died during the follow-up. Conclusion:The one-stitch preventive ileostomy has the advantage of ileostomy closure, which can reduce the operation time, volume of intraoperative blood loss and shorten the incision length effectively, so as to reduce the incidence of postoperative incision infection related complications.
