Abstract
A common operation for patients with complicated sigmoid diverticulitis is resection and placement of an ostomy (Hartmann procedure). This population-based study examines that proportion of ostomates who undergo reversal. In the California inpatient file, patients admitted for acute diverticulitis in 1995 were identified, including a subset that had surgical resection. Data regarding receipt of ostomy were obtained (4-year follow-up). Demographics and clinical data (procedure, ostomy reversal, time to reversal, comorbidity score, and complications) were collected. In 1995, 11,582 admissions for diverticulitis occurred in California. Of these, 24.2 per cent (n = 2808) underwent surgery at admission; 88.9 per cent were sigmoid/left colectomies; and 41.7 per cent had a Hartmann procedure. Patients with ostomies were older (P = 0.0004) and male (P = 0.03). Median comobidity score was the same for patients with or without an ostomy. Of the 1176 patients who had the Hartmann procedure, 65 per cent underwent reversal (mean 143 days). A larger proportion of men than women had their ostomies reversed (74.5% vs 55.9%, respectively, P < 0.0001). Median comorbidity scores for both groups were low, 0 for those reversed and 1 for nonreversed. Our study shows that although the majority of patients had their ostomies reversed, over 35 per cent did not at 4-year follow-up. Further studies are required to evaluate how this rate may be improved.
