title: Outcomes of laparoscopic colorectal surgery in obese and nonobese patients: a case-matched study of 180 patients.
abstract: BACKGROUND
  Because it has been suggested that obese patients may be at higher risk of morbidity and mortality after surgery, we conducted a prospective case-matched study to compare outcomes of elective laparoscopic colorectal surgery in obese and nonobese patients.
  
  
  METHODS
  Sixty-two consecutive nonselected obese patients (body mass index > or =30 kg/m(2)) were matched with 118 nonobese patients. Postsurgical mortality and morbidity were defined as in-hospital death and complications.
  
  
  RESULTS
  Cardiopulmonary comorbidities were significantly more frequent in obese compared with nonobese patients (44% vs 24%, P < .01). Obesity was significantly associated with increased mean operating time (268 +/- 74 min vs 232 +/- 59 min, P < .001), and conversion rate (32% vs 14%, P < .01). The mortality rate was nil. The overall postsurgical morbidity rate (31% vs 19%, P = not significant) and mean hospital stay (11 +/- 10 days vs 9 +/- 8 days, P = not significant) were similar in obese and nonobese patients.
  
  
  CONCLUSIONS
  The results of this large case-matched study suggest that laparoscopic approach for colorectal surgery is feasible and safe in obese patients.
