No Association between staging operation and the 5-Year Risk of Reoperation in Patients with Crohn's Disease.

The aim of this study was to investigate the impact of staging operation on the risk of reoperation in patients with CD who underwent primary bowel resection. This was a retrospective study of 980 patients with CD who were hospitalized in Jinling Hospital Affiliated to Nanjing Medical University between January 1, 2001, and October 1, 2016. The patients were grouped according to staging operation (n = 64) and one-stage operation (n = 148). Postoperative intestinal function recovery time, postoperative short-term complications, and reoperation rates were compared between the two groups. There was significant difference in disease behavior between the staging operation group and the one-stage operation group. There was no significant difference in postoperative tolerance of enteral nutrition among groups (P > 0.05). Obvious differences were found in the comparison of the first time of exhaustion, defecation after operation, postoperative length of stay and postoperative complications among groups (all P < 0.05). There was no difference in the 5-year cumulative reoperation-free rates between the two groups (P > 0.05). In conclusion, surgical intervention at proper time and appropriate operation during operation are essential for patients with CD. It is believed that staging operation with ostomy followed by intestinal anastomosis is feasible when there are more than two risk factors for postoperative intra-abdominal infectious complications.
