Laparoscopic Reversal of the Biliopancreatic Diversion with Duodenal Switch: a Step by Step Video Case.

BACKGROUND

Despite the success of the Biliopancreatic Diversion with Duodenal Switch procedure (BPD-DS) in weight loss and comorbidities resolution, reversal of BPD-DS is necessary in 0.2-0.6% of BPD-DS cases for vitamin, protein, and other micronutrient deficiencies. Different techniques are available to reverse the malabsorptive component of the BPD-DS.

METHODS

A retrospective chart review for a 37-year-old female patient who presented with lower leg edema and signs of malnutrition 5 years after a BPD/DS. The patient was not compliant with the required daily vitamin and protein intake. Thus, after extensive discussion with the patient, a decision was made to reverse the malabsorptive component of the BPD-DS.

RESULTS

A laparoscopic reversal of the malabsorptive component of the BPD-DS was concluded by transecting the roux limb distally at the ileo-ileal anastomosis and reconnecting it to the proximal jejunum thus substantially lengthening the common channel for absorption. At 6 months follow-up, the patient normalized her vitamin deficiency and had a normal level of serum protein. Her weight, BMI, EWL%, and TBWL% were 72 kg, 27.5 kg/m, 90%, and 45%, respectively.

CONCLUSIONS

Proper nutrition and vitamin supplementation is essential to avoid nutritional complications. Different techniques are available to reverse the malabsorptive component of the BPD-DS. However, no standard approach is adopted by the surgical community. We demonstrate our preferred technique in reversing the malabsorptive component of the BPD-DS.
