Description of intervention(s) / exposure
This project will be designed as a multicentre randomised controlled single-blinded study. The study will be conducted in consecutive adults undergoing planned pancreaticoduodenectomy with planned antecolic Billroth II gastrojejunostomy reconstruction in the setting of malignancy involving the stomach, duodenum, pancreas, or bile duct.

Patients will be randomised to:
- Pancreaticoduodenectomy with antecolic Billroth II Gastrojejunostomy plus Braun enteroenterostomy
- Pancreaticoduodenectomy with antecolic Billroth II Gastrojejunostomy without Braun enteroenterostomy
Patients will be observed daily by the treating team delayed gastric emptying (DGE)Participants will be recruited by the research team. The intervention is by the treating surgeon. The intervention is the operation itself as described by the randomisation. Participants will be checked daily as standard practice. QOL EQ5DL will be asked preoperatively on day 30 and day 90. Day 30 and 90 may be via phone or in follow-up clinics.

Location: during pancreaticoduodenectomy with antecolic Billroth II Gastrojejunostomy surgery and throughout the hospital stay and both surgeries are standard operative techniques.

Outcomes
Primary outcome [1] 329829 0
delayed gastric emptying
DGE is defined with 3 different grades by the ISGPS.1
- Grade A – Nasogastric intubation lasting more than 3 postoperative days, or the inability to tolerate a solid diet by post-operative day 7
- Grade B – Nasogastric intubation lasting for 8 to 14 days, the need for reinsertion of the nasogastric tube after 7 days, or the inability to tolerate a solid diet by post-operative day 14
- Grade C – Nasogastric intubation lasting more than 14 days, the need for nasogastric reinsertion after 14 days, or the inability to tolerate a solid diet by postoperative day 21.
This will be assessed independently by the research team.

Statistical methods / analysis
The current baseline of DGE incidence with standard Billroth II reconstruction is approximately 30%.20, Literature suggests that BE could reduce DGE rates to somewhere between 10-15%. A single interim analysis is planed once outcome data are available for 102 patients (62 per arm). The study is designed to control the family-wise error rate to 0.025, with an alpha spending of 0.005 at interim and 0.002 at final. The study will have 80% power to detect a DGF incidence of 6.5% in the intervention group at the interim analyses (using a one-sided alpha of 0.005) and a 3.5% rate at the final analysis (using a one-sided alpha of 0.02) 13.5% at the final analysis, and a 10% dropout so therefore 132 patients in each group would need to be randomised making a total of 264 participants required. We have elected to use a one-sided test as repeated research has shown that BE does not increase the incidence of DGE.
An interim analysis will be conducted after outcome data are available for 102 patients. The purpose of the interim analyses will be to assess futility or superiority. The trial will be considered to stop for futility if the conditional power of rejecting the null hypotheses at the final analysis is less than 20%. The trial will be considered to stop for superiority if the one-sided p-value testing the null hypothesis that the DGE incidence rates are the same in both groups using a chi-square test is less than 0.005.
