METHODS: A retrospective study of the medical records of all patients submitted to banded and non-banded RYGB between 2000 and 2020 was conducted. Clinical data (age, gender, weight, body mass index-BMI, comorbidities, %TWL, and the prevalence of vomiting) and laboratory data (hemoglobin, serum iron, albumin, and vitamin B12) were obtained preoperatively and at 6 months, 1, 2, 3, 5, 7, and 10 years for both groups and at 12, 15, and 20 years after banded RYGB.
RESULTS: In total, 858 patients underwent RYGB: 409 underwent banded RYGB and 449 underwent non-banded RYGB. In the preoperative period, banded RYGB patients were heavier and had higher rates of hypertension and dyslipidemia. The %TWL was higher in the banded RYGB group up to 7 years. The prevalence of vomiting is much higher in this group, which also had lower laboratory test values. Of the banded RYGB patients, 9.53% had to have the silicone ring removed after presenting complications.
CONCLUSIONS: Banded RYGB promotes significantly higher rates of TWL at the expense of a higher frequency of food intolerance and vomiting.
方法:对2000年至2020年间提交给带状和非带状RYGB的所有患者的病历进行了回顾性研究。临床数据(年龄,性别,体重,体重指数-BMI,合并症,%TWL,以及呕吐的患病率)和实验室数据(血红蛋白,血清铁,白蛋白,和维生素B12)在术前和6个月时获得,两组均为1、2、3、5、7和10年,并且在带状RYGB后12、15和20年。
结果:总计,858例患者接受了RYGB:409例接受了带状RYGB,449例接受了非带状RYGB。在术前期间,带状RYGB患者体重较重,高血压和血脂异常的发生率较高。在长达7年的带状RYGB组中,TWL的百分比更高。这一组的呕吐患病率要高得多,也有较低的实验室测试值。在带状的RYGB患者中,出现并发症后,9.53%的人必须去除硅胶环。
结论:带状RYGB显著提高了TWL的发生率,但以更高的食物不耐受和呕吐为代价。
