Roux-en-Y gastric bypass is a surgical technique widely used in the treatment of obesity. It is unclear, however, if the length of the biliopancreatic and alimentary limb interferes with the magnitude of weight loss.
To evaluate if the length of these limbs is related to the percentage of weight loss one year after surgery.
One hundred and twenty obese people underwent surgery between 2009 and 2011. Patients were inserted into four groups: A) biliopancreatic limb with 50 cm length and alimentary limb with 100 cm length; B) biliopancreatic limb with 50 cm length and alimentary limb with 150 cm length; C) biliopancreatic limb with 100 cm length and alimentary limb with 100 cm length; D) biliopancreatic limb with 100 cm length and alimentary limb with 150 cm length. Age, gender, body mass index and the percentage of total weight loss were analyzed. Data were collected preoperatively and one year after surgery. The groups were compared and weight loss compared between groups.
The follow-up occurred in 78.3% of the sample. The composition of the groups was similar, with no statistical significance. The average age was 43 years in groups A, C and D and 42 years in group B. The female gender predominated in all groups (about 60% of the sample). The mean body mass index was 46 kg/m2 for groups A, C and D and 42 kg/m2 in group B. The percentage of weight loss was 33% for group A and 34% for groups B, C and D. There was no significant difference among groups.
Different lengths of the biliopancreatic and alimentary limbs did not affect the percentage of total weight loss.
Roux-en-Y胃旁路术是一种广泛应用于肥胖症治疗的外科手术技术。然而，胆胰支和消化道支的长度是否会影响体重减轻的幅度尚不清楚。
评估这些支的长度与术后一年体重减轻百分比之间是否存在关联。
2009年至2011年期间，120名肥胖患者接受了手术。患者被分为四组：A组，胆胰支长度为50厘米，消化道支长度为100厘米；B组，胆胰支长度为50厘米，消化道支长度为150厘米；C组，胆胰支长度为100厘米，消化道支长度为百100厘米；D组，胆胰支长度为100厘米，消化道支长度为150厘米。对年龄、性别、体重指数和总体重减轻百分比进行了分析。术前和术后一年收集数据。对各组进行比较，并比较组间体重减轻情况。
78.3%的样本进行了随访。各组的构成相似，无统计学意义。A、C和D组的平均年龄为43岁，B组为42岁。所有组中女性占主导（约占样本的60%）。A、C和D组的平均体重指数为46kg/m²，B组为42kg/m²。A组的体重减轻百分比为33%，B、C和D组为34%。各组之间无显著差异。
胆胰支和消化道支的不同长度不影响总体重减轻百分比。
