Schematic demonstration of the “intentional internal drainage tube method” applied in the third surgery. a The distal pancreas was anastomosed to the elevated R-Y jejunal limb with an external MPD stent tube (A). b A single-lumen silicone drainage tube (B) was placed through the jejunal hole such that the tip of the tube was located in the peritoneal cavity (C). This hole was occupied with tube B, the “intentional internal drainage tube,” by the tobacco suture. c A thin tube for continuous suction (D) was inserted in tube B. The jejunal blind stump (E) was fixed to the abdominal wall and drained into tubes A, B, and D outside of the body without running through the peritoneal cavity. Extra external drainage tubes (F) were placed
