BACKGROUND: Weight loss following gastrectomy for @entity1 with @entity356 has not been well characterized. We assessed the impact of @entity1 and procedure-specific variables on postoperative @entity353 following gastrectomy for @entity5 . METHODS: A prospectively maintained @entity356 database identified @entity1 undergoing gastrectomy for @entity5 . Clinical and pathologic characteristics, baseline body mass index (BMI), and postoperative weights were extracted. Change in weight was analyzed by percent change in weight and absolute change in BMI. @entity35628 models were used to test whether the rate of change in weight over time differed by factors of interest. RESULTS: Of 376 consecutive @entity1 who underwent resection for @entity356 , 55  % were male, median age 66  years, and mean preoperative BMI 27.1 (range 16.2-45.6). Total gastrectomy was associated with more @entity353 than subtotal gastrectomy at 1  year (15 vs. 6  %, early stage; 17 vs. 7  %, late stage). Maximum weight change was observed at 6-12  months after operation and remained stable or improved at 2  years. For early- and late-stage @entity1 , median percent @entity353 at 1  year was greater for BMI  >=   30 versus BMI  <  30 (14 vs. 8  %, early stage; 15 vs. 9  %, late stage). CONCLUSIONS: The extent of @entity353 after gastrectomy for @entity356 is dependent on preoperative BMI and extent of gastric resection. Maximum weight change is expected by 12  months after operation and will stabilize or improve over time.
