Obesity Surgery, 09/12/2011
Vage V et al. – Patients with a remnant stomach of 100–120 ml, and alimentary limb (AL) and common channel (CC) with individually adapted lengths had a larger weight loss and better vitamin D status postoperatively without an increase in side effects.
Methods- All patients eligible for a 2-year follow-up (n=182) was included in the study.
- Thirty-five patients (group A) had a gastric remnant with a volume of approximately 200 ml, an alimentary limb (AL) of 250 cm, and a common channel (CC) of 100 cm, while 147 patients (group B) had a gastric remnant of 100–120 ml, an AL of 40%, and a CC of 10% of the small bowel length.
- Preoperative variables, such as body mass index (BMI), sex, age, and factors that might influence weight loss, and postoperative weight loss and side effects were registered and compared.
- Preoperatively, the BMI was 50.6 in group A and 52.1 in group B (ns), with no difference in age, sex, or variables that might influence weight loss.
- At 2 years, the BMI was 33.1 in group A (n=34) and 28.5 in group B (n=119) with an adjusted difference in weight loss of 5.6 BMI units between the groups (p<0.001).
- Vitamin D status was also better in group B than in group A at follow-up, while there was no difference in side effects.
