Diverticulitis in the young patient.

Although predominantly a disease in older adults diverticulitis does affect younger patients. The disease has been described as not only rare but virulent by some authors, and a young patient age is considered to be a relative indication for early sugery. The goal of this study was to evaluate the experience of the Louisiana State University Health Sciences Center-Shreveport and affiliated hospitals with diverticulitis in young patients. This study was a retrospective chart review of 22 patients with diverticulitis age 40 years and younger over the past 20 years. Inclusion criteria were either a diagnosis of diverticulitis confirmed at surgery or positive CT findings and/or a positive contrast enema. The mean age in this study was 32.1 years (range 16-40). All 22 patients presented with abdominal pain. The next most common symptom was nausea and/or vomiting in 45 per cent followed by fever and chills in 36 per cent. Twelve patients had abdominal CTs on admission, and 87 per cent had positive findings. Eighteen patients underwent an operation. Four patients were treated nonoperatively. Nineteen patients had diverticulitis of the sigmoid colon. The remaining three had right-sided diverticulitis. Two patients underwent right hemicolectomy, and one underwent cecectomy. Of the 15 patients with sigmoid diverticulitis 12 (80%) underwent a two-stage procedure of sigmoid colectomy, end colostomy, and Hartmann's pouch. Three patients (20%) underwent a one-stage procedure of sigmoid colectomy and primary anastomosis. Two of three patients undergoing a one-stage procedure required reoperation. Postoperative complications occurred in 10 of 18 patients for an overall incidence of 56 per cent. Two of these patients had septic complications. Both of these patients had a delay in time from admission until operation: one for 7 days and the other for 10 days. There was one death in the series. Colostomy closure was performed successfully in nine of 12 (75%) patients. The mean time interval before closure was 7.7 months, (range 3-14). Patients with two-stage procedures on initial admission fared better than those with one-stage procedures. The overall mortality was 4.5 per cent. There was a high overall complication rate of 56 per cent in patients undergoing an operation. Two patients who had a delay in time from admission to operation had septic complications. Early surgical intervention should be considered in this clinical setting. In summary, although rare, diverticulitis in the young patient is often a fulminant illness requiring operation early in the disease process.
