Mayo clinic PDF file I have it. DS versus BPD w/DISTAL GASTRECTOMY Scopinaro procedure

DUODENAL SWITCH

First described as a bariatric operation by Hess and

the DS was developed as a hybrid procedure combining the

BPD reported by Scopinaro et al^ and the operation described

by DeMeester et al.-^ Although conceptualized to

avoid the risk of stomal ulceration and dumping symptoms,

large case series have reported a decreased incidence of

severe protein-energy malnutrition with the DS technique

compared to that reported with BPD. The procedure involves

transection of the first portion of the duodenum with resection

of the greater curvature of the stomach, leaving a 100- to

150-mL lesser curvature-based gastric sleeve with an intact

antrum and pylorus (Figure 4, A). The proximal ileum is

divided 250 cm from the ileocecal junction, and the

biliopancreatic limb is anastomosed to the distal ileum creating

a short (100 cm) common channel.
