Laparoscopic Cholecystectomy Associated with Gastric Bypass Surgery: A Safe Approach for Morbid Obesity Patients?

Background: Some researchers suggest that gastric bypass surgery plus cholecystectomy increases post-surgical complications. However, there is not studies that exploring this association.

Objective: To compare the post-surgical complications between patients operated on cholecystectomy and who not among obese persons meeting criteria for gastric bypass surgery in Medellín, Colombia.

Method: A case-control study was done. In this research participated a total of 134 patients over 18 years old who met criteria for gastric bypass surgery due morbid obesity; 88.1% were women. A group of 23 patients were operated on cholecystectomy plus gastric bypass surgery, and other group of 112 patients with-out cholecystectomy was taken as control. Confounding variables were controlled by logistic regression.

Results: The mean total observation time from the procedure was 67.1 minutes (SD=27.1), and for hospital stay was 50.2 hours (SD=18.8). A total of three people (2.2%) presented early minor post-surgical complications. The surgical time was higher for patients with cholecystectomy than patients without it {86.9 minutes (SD=52.0) vs. 63.0 (SD=15.8) p=0.001}. The hospital stay was similar in both groups {47.4 hours (SD=4.6) vs. 50.8 (SD=20.5) p=0.429}. The frequency of complications was also comparable in both case and control patients (Fisher’s Exact Test, p=1.00, two-tailed).

Conclusions: Cholecystectomy additional to gastric bypass surgery increases significantly time surgery. Nevertheless, it does not alter number of early complications among patients who receive gastric bypass surgery or hours of hospital stay.

Key words: Cholecystectomy, gastric bypass, laparoscopy, obesity, morbid (Palabras MeSH).
