BACKGROUND: Surgical management of diverticulitis is evolving and the decision to offer elective sigmoidectomy for diverticulitis has become more individualized. However, preoperative variables that may predict recurrent diverticulitis after resection and guide surgical decision-making were not well studied. METHODS: This was a retrospective chart review with a prospective questionnaire follow-up of patients. Patients who underwent elective sigmoidectomy for diverticulitis from 2002 to 2016 at a tertiary academic colorectal surgery practice were included and their medical records reviewed. They were then contacted with a questionnaire to inquire about recurrence of diverticulitis since resection. The primary outcome was rate of recurrent diverticulitis after elective sigmoidectomy. The secondary outcome was risk factors for recurrence after sigmoidectomy. RESULTS: Of 662 patients who underwent elective sigmoidectomy for diverticulitis, 361 had long-term follow-up data available. Mean follow-up was 86 months. Indication for surgery was uncomplicated recurrent diverticulitis in 50%. Recurrent diverticulitis developed in 15 (4.2%) patients. Mean time to recurrence was 55 (range, 6-109) months. All recurrences were confirmed by CT scan. Univariate analysis showed that preoperative diagnosis of irritable bowel syndrome and uncomplicated recurrent diverticulitis was significantly more prevalent in patients who experienced recurrent diverticulitis after sigmoidectomy (p = 0.049 and p = 0.02); however, these variables did not predict recurrence after resection. CONCLUSIONS: Overall rate of recurrent diverticulitis after elective sigmoidectomy was 4.2%. Preoperative diagnosis of irritable bowel syndrome and uncomplicated recurrent diverticulitis was associated with but not significant predictor of recurrence after elective resection.
