Background: Historical training instructs surgeons to, "never let the sun set on a small bowel obstruction (SBO)" due to concern for bowel ischemia. However, the routine use of computed tomography scans for ruling out ischemia provides the opportunity for trial of nonoperative management, allowing time for resolution of adhesive SBO. In light of advances in practice, little is known about how surgeons manage these patients, in particular, whether there is consistency in the stated duration for safe nonoperative management.
Methods: Using a case vignette (a patient with computed tomography scan diagnosed complete SBO without bowel ischemia), we interviewed a purposive sample of general surgeons practicing in Washington State to understand stated approaches to clinical management. Interview questions addressed typical practice, preferred timing of surgery, and approach. We conducted a content analysis to understand current practice and attitudes.
Results: We interviewed 15 surgeons practicing across Washington State. Surgical practice patterns for patients with SBO varied widely. The period of time that surgeons were willing to manage patients nonoperatively ranged from 1-7 d. Interviews revealed insight into surgical decision-making, the importance of patient preferences, variation in practice, and evidence gaps. All surgeons acknowledged a lack of evidence to support appropriate management of patients with SBO.
Conclusions: Interviews with practicing surgeons highlight a changing paradigm away from routine early surgery for patients with adhesive SBO. However, there is lack of consensus in the appropriate duration of nonoperative management and practices vary considerably. These revealed attitudes inform the feasibility and design of future randomized studies of patients with adhesive SBO.
