Duodenum-preserving resection and Roux-en-Y pancreatic jejunostomy in benign pancreatic head tumors

Figure 1 B-ultrasonic examination and computed tomography scan of case 1. A: Enhanced computed tomography image of BTPH shows a low density in the pancreatic head mass at 3.5 cm × 3.2 cm. The tumor displayed ill-defined borderline in calcified lesions; B: Shape and structure of BTPH. The tumor is an oval shape and some necrotic tissue existed inside the tumor; C: Wound surface area of the pancreas. Measuring wound surface area of the pancreas is 6.3 cm × 6.5 cm after the tumor removed; D: Illustration for operative repair with Roux-en-Y pancreaticojejunostomy is shown with proximal pancreatic end ligated and a stent is put into distal pancreatic resection. BTPH: Benign tumors of the pancreatic head.
