title: Patients with less than three episodes of diverticulitis may benefit from elective laparoscopic sigmoidectomy.
abstract: BACKGROUND
  This study was designed to asses the predictive factors of postoperative complications in patients who underwent a laparoscopic elective approach for recurrent diverticulitis and to determine the relationship between the number of acute episodes and surgical morbidity.
  
  
  METHODS
  A retrospective analysis was performed on patients with colonic diverticular disease treated by an elective laparoscopic approach between July 2000 and November 2007. The variables studied were age, sex, BMI, ASA, number of previous acute episodes, local severity, abdominal surgery history, comorbidity, and laparoscopic training of the surgeon. Logistic regression analysis was used to establish significant results.
  
  
  RESULTS
  A total of 137 patients were analyzed; 87 (63.5%) were men with a mean age of 56.7 (range, 27-89) years. Intraoperative and postoperative complications occurred in 2.9% (n = 4) and 12.4% (n = 17) of the patients respectively. Conversion rate was 9.4% (n = 13). Local severity (odds ratio (OR), 16.34; 95% confidence interval (CI), 4.1-64.5, p = 0.00007), history of abdominal surgery (OR, 3.02; 95% CI, 0.8-11.5; p = 0.02), and the training of the operating surgeon (OR, 4.8; 95% CI, 1.02-22.7; p = 0.001) were significant risk factors related to surgery conversion. A history of three or more acute episodes was significantly associated with a high severity of local process and was a risk factor related to conversion (OR, 2.6; 95% CI, 0.5-12.3; p = 0.22). The severity of the local process seems to be a risk factor for perioperative complications. A significant association (chi2, 4.45; p = 0.03) between conversion and postoperative complications also was observed (OR: 3.79, 95% CI, 1.02-14.07; p = 0.04).
  
  
  CONCLUSIONS
  A history of three or more acute episodes of diverticulitis with conservative treatment is associated with a high severity of the local process during laparoscopic sigmoidectomy and increases the rate of conversion and perioperative complications.
