Second-stage robot-assisted biliopancreatic diversion with duodenal switch after sleeve gastrectomy.

Biliopancreatic diversion (BPD) was initially described in 1979 and consisted of a distal gastrectomy with a 250-mL stomach pouch and a distal intestinal bypass with a 50 to 100-cm common channel resulting in malabsorption of dietary fat (Scopinaro et al. Br J Surg. 66(9):618-20, 1979). Later, several modifications (sleeve gastrectomy, pylorus preservation, and duodenal switch) were proposed to improve incidence of postoperative dumping syndrome, diarrhea, and anastomotic ulcerations (Lagacé et al. Obes Surg. 5(4):411-8, 1995). Gagner et al. developed a simplified and reproducible approach for laparoscopic BPD with duodenal switch (BPD-DS) after sleeve gastrectomy (Ren et al. Obes Surg. 10(6): 514-23, 2000). BPD-DS has been considered as one of the most difficult bariatric procedures for its surgical complexity and postoperative metabolic complications management. In this regard, the number of BPD-DS has remained extremely low (<4 %). We hypothesize that robotic approach could facilitate the feasibility of BPD-DS procedure. In this multimedia video (8 min), we present a step-by-step robotic BPD-DS.
