Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
The primary endpoint was defined as the decrease of delayed gastric emptying. The secondary endpoints were QOL, mortality and morbidity, including pancreatic fistula, intra-abdominal hemorrhage, and intra-abdominal abscess. Patients were recruited into this study before surgery, on the basis of whether pancreatic head resection was anticipated at Wakayama Medical University Hospital(WMUH) for pancreatic head and periampullary disease, and appropriate informed consent was obtained. Exclusion criteria was 1) patients with severe complications which were possible to prolong hospital stay, 2) patients who were diagnosed inadequacy for this study by a physician, 3) patients with a previous gastric resection, and 4) patients without an informed consent.

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
1
In PpPD, the proximal duodenum was divided 3-4cm distal to the pylorus ring
pylorus-preserving pancreaticoduodenectomy
pylorus-preserving resection is division of the duodenum 3-4cm distal to the pylorus
2
In PrPD, the stomach is divided just above the pylorus ring. the nearly total stomach more than 95% was preserved.
pylorus-resecting pancreaticoduodenectomy
In PrPD, the stomach is divided just above the pylorus ring. The nearly total stomach more than 95% was preserved.
