Purpose: We have evaluated changes of body composition for patients that underwent a radical gastrectomy for stomach cancer by the use of available bioelectrical impedance analysis during the first year following surgery. We plan to
utilize these findings in nutritional and physiological studies.
Materials and Methods: We evaluated clinical changes in body composition in patients using the bioelectrical impedance method (Inbody 4.0, Biospace, Korea), between November 2003 to November 2004. A total of 98 patients agreed
to enroll in this study among all of the patients that underwent a radical gastrectomy.
Results: The average weight decreased by 6.7%, and 9.4%, within the first and 6 months after surgery, respectively (P＜0.01). The fat free mass (FFM) dropped by 4.9% within the first month and there were no more changes after this period (P＜0.01). The fat mass (FM) and visceral fat area (VFA) decreased 24.3% and 14.1% within the first 6 months (P＜0.01), respectively. The reduction effects for female patients were greater than for male patients for weight, FFM and VFA (P＜0.05). The edema index was higher in patients with stage III-IV disease than in patients with stage I-II disease (P＜0.05). There were significant differences for Billroth I and BillrothI II patients as compared to patients that underwent an esophagojejunostomy for a reduction of the FM, as measured in the in the 12th month after surgery (27.6%, 22.1%, and 41.2%, respectively; P＜0.05).
Conclusions: Since nutritional supplementation and an improvement in body weight loss after a radical astrectomy is significantly related with quality of life, nutritional and physiological studies should be greatly considered. In this study, bioelectrical impedance analysis was very useful in analyzing the diminution of body composition and we hope
this study on the nutritional and physiological aspects related to a radical gastrectomy will be useful for later studies.
