Billroth II reconstruction, in which a loop of jejunum is mobilized and anastomosed to the gastric remnant

Billroth II reconstruction

This is an additional surgical connection (anastomosis) created between two parts of the small intestine, specifically between the afferent (incoming) and efferent (outgoing) limbs of the jejunum near the gastrojejunostomy (the new connection between the stomach and small intestine created during a Billroth II procedure).

The primary aim of this trial is to rigorously evaluate the comparative benefits and potential risks associated with Billroth II reconstruction with Braun anastomosis versus Billroth II reconstruction alone following distal gastrectomy with D2 lymphadenectomy in patients diagnosed with gastric cancer. This assessment focuses on delineating the therapeutic efficacy, safety profile, and overall clinical outcomes of these two surgical approaches in treating this condition.

Billroth II With Braun Anastomosis Versus Billroth II Anastomosis After Radical Distal Gastrectomy With D2 Lymphadenectomy for Gastric Cancer: a Randomized Controlled Trial

The preoperative and postoperative QoL of patients between the two groups.

Changes in body weight (kg) or BMI from baseline

e.g., anastomotic leakage, anastomotic bleeding assessed by laboratory test in combination with clinical features, radiological diagnostic methods, endoscopy, diagnostic laparoscopy.

e.g., food residue and bile reflux (assessed according to the RGB classification).

Open pancreatoduodenectomy with Braun enteroenterostomy

Participants will undergo open pancreatoduodenectomy (PD). The reconstruction technique will not be standardized. In addition to the reconstruction technique used, a side-to-side anastomosis will be created between the afferent and efferent jejunal limbs of the gastrojejunostomy (GJ) at 20 cm distance from the GJ. The anastomosis will be hand-sewn with monofilament PDS 3-0 one-layer running suture.

Braun anastomosis

Participants will undergo open pancreatoduodenectomy (PD). The reconstruction technique will not be standardized. The surgeon is able to perform the PD as normally would be done (antecolic, retrocolic, pylorus-preserving or with distal gastric resecting).

The goal of this clinical trial (REMBRANDT) is to evaluate the effectiveness of adding an extra connection (i.e. 'Braun anastomosis') after standard reconstruction in pancreatic head resection in reducing the incidence of delayed gastric emptying.

Rationale/hypothesis: The addition of Braun enteroenterostomy (BE) reduces the incidence of delayed gastric emptying (DGE) resulting in lower morbidity and healthcare costs after pancreatoduodenectomy.

Objective: To assess the effectiveness of adding BE in reducing DGE in patients undergoing open pancreatoduodenectomy.

Study design: A multicenter, patient and observer blinded, registry-based randomized controlled trial.

Study population: Patients undergoing an open pancreatoduodenectomy for all indications.

Intervention: Braun enteroenterostomy (BE), or Braun anastomosis, in addition to usual care.

Usual care/comparison: Pancreatoduodenectomy with standard Child reconstruction.

Main endpoints:

1. Incidence of DGE Grade B/C (according to International Study Group of Pancreatic Surgery (ISGPS)
2. Incidence of postoperative pancreatic fistulas (POPF) Grade B/C (according to ISGPS), anastomotic leak, complications, hospital length of stay, functional outcome at 12 months, in-hospital mortality, 30-day mortality, healthcare costs.

Sample size: 256 in total, 128 per arm

Nature and extent of the burden and risks associated with participation, benefit and group relatedness: Patients undergoing open pancreatoduodenectomy have an increased risk of postoperative complications such as DGE, POPF and anastomotic leak. The addition of BE, which is an anastomosis, could also result in a leak. However, this risk is diminishable compared to the risks of DGE and DGE related other complications like anastomotic leaks associated with standard pancreatoduodenectomy. Moreover, previous cohort studies involving BE do not describe an increased risk of adverse outcomes for BE.

Patients will be blinded considering their treatment allocation. The house officer, ward nurses and data managers who extract data concerning the primary and secondary endpoint will be blinded for the allocation as well. For this reason, this will be a patient- and observer blinded RCT.

The Effectiveness of Adding Braun Anastomosis to Standard Child Reconstruction After Pancreatoduodenectomy

The Effectiveness of Adding Braun Anastomosis to Standard Child Reconstruction to Reduce Delayed Gastric Emptying After Pancreatoduodenectomy (REMBRANDT): a Multicenter Randomized-controlled Trial

DGE is defined by the need for maintenance of the nasogastric tube (NGT), need for reinsertion of NGT for persistent vomiting after postoperative day (POD) 7, or inability to tolerate a solid diet.

Any measurable volume of drain output with an amylase level of more than 3 times the upper limit of normal serum amylase and clinically relevant condition or development of the patient directly related to the POPF.

Anastomotic leaks of the hepatojejunostomy (HJ) or Braun enteroenterostomy (BE).

Anastomotic leaks of the HJ manifest as bile leakage. This is defined as "fluid with an increased bilirubin concentration in the abdominal drain or in the intra-abdominal fluid on or after postoperative day 3, or as the need for radiologic intervention because of biliary collections or relaparotomy resulting from bile peritonitis. Increased bilirubin in the drain is defined as bilirubin concentration more than 3 times greater than the serum bilirubin concentration.

An anastomotic leak of the BE is present when an abdominal CT with contrast shows leakage of contrast from the BE or when during relaparotomy dehiscence of the BE is apparent.

Scored according to the modified Clavien-Dindo classification for surgical complications. Grade III and higher are considered clinically relevant in this study.

The time period in days between hospital admission and discharge from the hospital.

Any death occurring 30 days after pancreatoduodenectomy.

The EQ-5D-5L standardized questionnaire will be used.

The European Organisation for Research and Treatment of Cancer (EORTC) QLQ-C30/PAN26 standardized quality of life questionnaires will be used.

The QoR-15 standardized questionnaire will be used.

Participants will be phoned to assess whether they have complaints of delayed gastric emptying ("afferent loop syndrome").
