Background: To identify factors associated with diverting ileostomy creation (DLI) in patients undergoing sigmoid colectomy for diverticular disease in a high volume colorectal unit and to obtain information for better preoperative patient counseling.
Methods: Patients who underwent sigmoid colectomy with colorectal anastomosis with or without DLI for diverticulitis between 01/1994-12/2014 were identified. Preoperative characteristics, surgeon practice year, individual surgeon and postoperative outcomes were compared between patients with DLI or not.
Results: 1320 patients were identified and DLI was created in 204 (15.4%) patients. DLI creation was associated with older age (p < 0.001), female gender (p = 0.01), higher ASA-class (p < 0.001), hypertension (p = 0.01), DM(p < 0.001), renal comorbidities (p < 0.001), preoperative steroid use (p = 0.03), preoperative anemia (p = 0.004), and open surgery (p < 0.001). While ileostomy creation rates did not vary over the years during the study period or with increased surgeons' experience, surgeon identity had significant impact on ileostomy creation (Rate range 6.8-60.7%, p < 0.001). Multivariate logistic regression analysis revealed that individual surgeon, open approach, preoperative steroid use, and disease-related factors remained independently associated with DLI creation.
Conclusion: Individual surgeon's practice affects the rate of diverting ileostomy creation in patients undergoing sigmoid colectomy for diverticular disease.
