Abstract
Background
Laparoscopy-assisted distal gastrectomy (LADG) has become a viable alternative treatment for patients suffering with early gastric cancer. Surgeons have long thought that obesity might increase the rate of intraoperative or postoperative complications. We set out to clarify the effect that obesity has on performing LADG for the treatment of early gastric cancer.
Methods
We retrospectively reviewed 97 patients who had undergone LADG for early gastric cancer between May 1998 and March 2004. We measured the degree of obesity by using the body mass index (BMI; kg/m2), and we compared the surgical outcomes between the normal BMI group (BMI < 23 kg/m2) and the high BMI group (BMI ≥ 23 kg/m2). We further subdivided the patients into four groups: normal BMI males and normal BMI females, and high BMI males and high BMI females, and we analyzed them in terms of operation times, numbers of retrieved lymph nodes, and rates of postoperative complications.
Results
There were no significant differences between the normal and high BMI groups in terms of the patients' characteristics, surgical outcomes, postoperative courses, postoperative complications, and operation times. There were no statistically significant differences in the number of retrieved lymph nodes or in the rate of postoperative complications among the four groups (P = 0.5030 and P = 0.3489, respectively). However, there was a statistically significant difference in operation times among the four groups (P = 0.004). Specifically, the males in the high BMI group required a longer operation time than did the females with a normal BMI (P = 0.006) and the females with a high BMI (P = 0.019).
Conclusions
For LADG in patients with early gastric cancer, obesity may affect the operation time, and men with high BMI require a longer operation time than do women with normal or high BMI.
