Laparoscopic cholecystectomy in the morbidly obese

Abstract

In the early days of video-assisted laparoscopic cholecystectomy (VLC), obesity was considered a contraindication for the procedure. We reviewed charts from 304 patients undergoing VLC; 90 patients were obese, and among these, according to a classification currently used by medical nutritionists and based on BMI, 45 were overweight (BMI > or = 25 < or = 29.9), 27 were considered conventionally obese (BMI > or = 30 and < 40) and 18 morbidly obese (BMI > or = 40). In this study we considered only the morbidly obese patients (5 males and 13 females). The average age was 42.3 years (range: 21-65) and the average weight 275 Ib (range: 186-331 Ib). Six patients had previously undergone abdominal surgery. All patients were symptomatic for gallstones, and 5 of them were suffering from acute cholecystitis. Mean operative time was 20 minutes (range: 10-45 minutes) longer than that of non-obese patients. No open conversion was necessary. No major postoperative morbidity and no cases of mortality occurred. The mean hospital stay and resumption of normal diet were similar to those of non-obese patients. Regardless of the higher postoperative risks after open cholecystectomy in obese patients (pulmonary complications, thromboembolism, wound infections and cardiovascular complications), we suggest VLC as the procedure of choice for cholecystectomy in these patients.
