Background:
Laparoscopic cholecystectomy (LC) is the treatment of choice for gallstones. Obesity was initially considered a contraindication to this approach. The aim of this report is to review our experience with LC, to evaluate the role of BMI in the outcome.
Methods:
The records of 1,804 patients who underwent LC for symptomatic cholelithiasis from May 1992 to January 2004 were analyzed retrospectively. Patients were divided into 5 groups according to their BMI: < or =24.9, 25.0-29.9, 30.0-34.9, 35.0-39.9 and > or =40 kg/m2.
Results:
Of the 1,804 patients [1,379 females (76.4%) and 425 males (23.6%)] who underwent LC, 431(23.9%), 924 (51.2%), 355 (19.7%), 68 (3.8%) and 26 (1.4%) had BMI values of < or =24.9, 25.0-29.9, 30.0-34.9, 35.0-39.9 and > or =40 kg/m2, respectively. Conversion to open cholecystectomy was required in 94 patients (5.2%), and complications occurred in 39 patients (2.2%). There was no correlation between BMI and the conversion rate (P=0.593) and complication rate (P=0.944), while the hospital stay was similar between the groups with successful LC. The only significant difference was the longer operating time in the two obesity groups (P<0.001).
Conclusions:
LC is effective and safe in patients with morbid obesity. As it carried low risks of conversion and perioperative complications, we suggest that LC is the select approach for these patients. Moreover, the rapid mobilization and hospital discharge following LC may provide extra benefit to these patients.
