Purpose:
To compare the effects of obesity on laparoscopy-assisted distal gastrectomy (LADG) and open distal gastrectomy (ODG).
Methods:
A retrospective study was conducted on 249 patients, who underwent LADG and 224 patients who underwent ODG.
Results:
The regression coefficient of the primary regression equation between operative time and body mass index (BMI) for LADG was greater than ODG; and between blood loss and BMI for LADG was almost the same as ODG. In overweight patients (BMI ≥25), no significant difference was seen between LADG and ODG regarding postoperative complications, and the benefits of the less-invasive nature of LADG were also seen in some parameters.
Conclusion:
Obesity-associated difficulties are more while performing LADG than during ODG; however, the influence of obesity on LADG decreases with surgical experience. Moreover, even in overweight patients, the benefits of the less-invasive nature of LADG still remain, but the degree of the benefits is smaller than that in nonobese patients.
