Laparoscopic cholecystectomy for acute cholecystitis: are intended operative approach, timing and outcome affected by BMI? A multicenter retrospective study.



Laparoscopy is the gold-standard for cholecystectomy after acute cholecystitis, but the issue is controversial in obese subjects.


We reviewed 464 patients operated for acute cholecystitis (59 open and 405 laparoscopic) over the last five years at St Orsola University Hospital-Bologna and Umberto I University Hospital-Rome, comparing retrospectively: 1) BMI < 30 (397 patients) and BMI =/> 30 (67 patients) and moreover 2) BMI < 25 (207 patients) and BMI =/> 25 (257 patients).


In the first comparison, obese patients showed higher cardiovascular co-morbidity (61.1% vs 44.5%, p=0.01), worse symptoms (Murphy's sign positive in 92.5% vs 80.8%, p=0.02; fever >38.5°C in 88.0% vs 76.0 %, p=0.02) and significant radiologic imaging (95.5% vs 85.1%, p=0.01) of acute cholecystitis. Laparoscopy was used in 83.6% of obese patients vs 87.9% without any difference, and operative time or conversion rate were similar. According to Tokyo Guidelines 2013, the number of patients who underwent surgery within 3 days or after 6 weeks was similar without statistical difference between the two groups. Hospital stay, morbidity and mortality were similar. Complications were seen in 25.4% of obese patients vs 15.9% (p= 0.03), mainly represented by wound infections. The second comparison did show no difference between two groups BMI =/>25 and BMI < 25.


Our retrospective multicenter study showed no difference related to intended operative approach, timing and outcome in higher BMI versus lower BMI patients operated for acute cholecystitis.
