Purpose
The effectiveness of the standard biliopancreatic diversion with duodenal switch (BPD/DS) in terms of weight loss has been demonstrated. Increasing the strict alimentary limb length while maintaining the length of the common channel could lead to similar weight loss while reducing side effects.
Materials and Methods
The objective was to evaluate the effect of increasing the strict alimentary limb length on weight loss, comorbidities, nutritional deficiencies, and quality of life 2 years after surgery, compared with standard BPD/DS. An exploratory randomized, double-blind study evaluated the results of LADS at 2 years in comparison with the standard BPD/DS. Common channel was kept at 100 cm in both groups while alimentary limb was created at 100 cm from Treitz angle in the LADS group and at 150 cm total in the BPD/DS group.
Results
Twenty patients were recruited from May 2013 to June 2015. Mean percentage of excess weight loss was statistically significantly lower in the LADS group at 24 months (81.6 ± 6.6% in the LADS group and 97.1 ± 11.1% in the BPD/DS group (p = 0.001). No significant difference regarding the rate of remission of comorbidities was noted. Mean calcium, vitamin D, hemoglobin, zinc, and copper levels were statistically lower in the BPD/DS group. Quality of life was significantly improved in both groups, with no statistically significant difference between the two groups.
Conclusions
At 24 months, weight loss was lower in the LADS group. However, no difference was observed in the improvement in quality of life. LADS technique was discontinued following this study.
