To determine the effect of an orogastric tube for calibration of the gastric pouch on percentage excess weight loss (%EWL) and percentage total weight loss (%TWL) after laparoscopic Roux-en-Y gastric bypass (LRYGB).
A retrospective case-matched control study in 132 patients. Group A (a 40 French orogastric tube was used to calibrate the gastric pouch) was compared to group B (no orogastric tube was used). All other surgical steps were identical in both groups. Postoperative %EWL and %TWL were recorded at 3, 6, 9, 12, and 24 months postoperatively.
Baseline characteristics and comorbidities were similar for both groups; a mean age of 43.6 years, 84% of the patients were female and mean initial BMI was 44 kg/m. At 24 months, 9% of the patients were lost to follow-up. At 1-year follow-up, %EWL and %TWL were 80% and 33.3% in group A versus 70% and 28.6% in group B with p = 0.013 and p = 0.007 respectively. At 2 years, EWL% and %TWL were 79.5% and 32.8% in group A and 67.18% and 28.1% in group B with a p value of 0.019 and 0.001 respectively. The use of a calibration tube, initial BMI, and age predicted the %TWL best with R squared at 30.7%.
The use of a calibration tube for creating the gastric pouch may lead to a higher %EWL and %TWL at 2-year follow-up. The standardization of the technique for LRYGB is desirable to achieve the maximum success rate in the surgical therapy of morbid obesity.
确定经口胃管校准胃袋对腹腔镜 Roux-en-Y 胃旁路术（LRYGB）后多余体重减轻百分比（%EWL）和总体重减轻百分比（%TWL）的影响。
对 132 例患者进行回顾性病例对照研究。A 组（使用 40Fr 经口胃管校准胃袋）与 B 组（未使用经口胃管）进行比较。两组的所有其他手术步骤均相同。术后 3、6、9、12 和 24 个月记录 %EWL 和 %TWL。
两组患者的基线特征和合并症相似；平均年龄为 43.6 岁，84%的患者为女性，平均初始 BMI 为 44kg/m。24 个月时，9%的患者失访。1 年随访时，A 组的%EWL 和 %TWL 分别为 80%和 33.3%，B 组分别为 70%和 28.6%，p=0.013 和 p=0.007。2 年时，A 组的 EWL%和%TWL 分别为 79.5%和 32.8%，B 组分别为 67.18%和 28.1%，p 值分别为 0.019 和 0.001。校准管的使用、初始 BMI 和年龄对%TWL 的预测最佳，R 平方值为 30.7%。
经口胃管校准胃袋可能导致 2 年随访时 EWL%和%TWL 更高。LRYGB 技术的标准化对于肥胖症手术治疗的最大成功率是可取的。
