Trends in diverticulitis management in the United States from 2002 to 2007.

OBJECTIVE To demonstrate the recent trends of admission and surgical management for diverticulitis in the United States. DESIGN Retrospective database analysis. SETTING The National Inpatient Sample database. PATIENTS Patients admitted to the hospital for diverticulitis from 2002 to 2007. MAIN OUTCOME MEASURES Patient characteristics, surgical approach, and mortality were evaluated for elective or emergent admission. RESULTS A total of 1,073,397 patients were admitted with diverticulitis (emergent: 78.3%, elective: 21.7%). The emergent admission rate increased by 9.5% over the study period. For emergent patients, 12.2% underwent urgent surgical resection and 87.8% were treated with nonoperative methods (percutaneous abscess drainage: 1.88% and medical treatment: 85.92%). There was only a 4.3% increase in urgent surgical resections, while elective surgical resections increased by 38.7.%. The overall rate of elective laparoscopic colon resection was 10.5%. Elective laparoscopic surgery nearly doubled from 6.9% in 2002 to 13.5% in 2007 (P < .001). Primary anastomosis rates increased for elective resections over time (92.1% in 2002 to 94.5% in 2007; P < .001). For urgent open operation, use of colostomy decreased significantly from 61.2% in 2002 to 54.0% in 2007 (P < .001). In-hospital mortality significantly decreased in both elective and urgent surgery (elective: 0.53% in 2002 to 0.44% in 2007; P = .001; urgent: 4.5% in 2002 to 2.5% in 2007; P < .001). CONCLUSION Diverticulitis continues to be a source of significant morbidity in the United States. However, our data show a trend toward increased use of laparoscopic techniques for elective operations and primary anastomosis for urgent operations.
