Abstract
BACKGROUND
The aim of this study was to assess the long-term results in patients with uncomplicated diverticulitis who had participated in the Antibiotics in Acute Uncomplicated Diverticulitis (AVOD) RCT, which randomized patients with CT-verified left-sided acute uncomplicated diverticulitis to management without or with antibiotics.
METHODS
The medical records of patients who had participated in the AVOD trial were reviewed for long-term results such as recurrences, complications and surgery. Quality-of-life questionnaires (EQ-5D™) were sent to patients, who were also contacted by telephone. Descriptive statistics were used for the analysis of clinical outcomes.
RESULTS
A total of 556 of the 623 patients (89·2 per cent) were followed up for a median of 11 years. There were no differences between the no-antibiotic and antibiotic group in recurrences (both 31·3 per cent; P = 0·986), complications (4·4 versus 5·0 per cent; P = 0·737), surgery for diverticulitis (6·2 versus 7·1 per cent; P = 0·719) or colorectal cancer (0·4 versus 2·1 per cent; P = 0·061). The response rate for the EQ-5D™ was 52·8 versus 45·2 per cent respectively (P = 0·030), and no differences were found between the two groups in any of the measured dimensions.
CONCLUSION
Antibiotic avoidance for uncomplicated diverticulitis is safe in the long term.
