a, b Autologous peritoneal interposition graft preparation. A 4 × 3 cm section of diaphragmatic parietal peritoneum was harvested from the right subcostal area. The section obtained was tubularized, using a 10-mm trocar as support model (a) by a running 6/0 prolene suture (b). c, d Operating field after successful portal trunk reconstruction with autologous peritoneal interposition graft (APG). The graft was anastomosed (yellow arrows), under proximal and distal clamping, right above the spleno-mesenteric confluence with two end-to-end prolene 6/0 sutures. SV, splenic vein; SMV, superior mesenteric vein
