Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
Participating centres must have an annual volume of at least 20 gastrectomies per year.
Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
There are many DSF-related complications leading to longer hospitalization times, such as intra-abdominal abscesses, wound infections, diffuse peritonitis, sepsis, malnutrition, pancreatitis, abdominal bleeding, and pneumonia. (3) DSF is often difficult to treat because of the highly enzyme-rich duodenal juice and deep location of the fistula. In a retrospective multicenter study (2) 3,685 patients undergoing gastrectomy for malignancies who developed 68 DSFs were analyzed; it was reported that DSF features had changed in the last 30 years and that DSF alone no longer leads to death; some complications observed in the past, such as fluid and electrolyte loss and dermatitis, have disappeared owing to improvements( in particular parenteral nutrition and wound care). However, additional new complications such as bleeding and fistulas of neighboring organs were emerging. Although medical therapy is associated with better outcomes, surgery is still mandatory in cases of severe abdominal sepsis or bleeding not otherwise manageable.
However, reoperation is often ineffective owing to postoperative edema and inflammation, and the prognosis of patients undergoing surgery for DSF remains very poor. To improve the outcome of these patients, many surgical procedures have been proposed from washing the peritoneal cavity and abdominal drainage to tube duodenostomy (14,15), closure of the fistula, fistula repair with a rectus abdominis flap (16), fistula closure by Roux-en-Y duodenojejunostomy(17,18), biliogastric diversion, laparostomy, and pancreatoduodenectomy (19) but surgeons are often unsure about the best management and the result are often unsuccessful.
In a recent Korean national RCT (6) on open (ODG) vs laparoscopic distal gastrectomy (LADG), the incidence of duodenal stump leakage after laparoscopyc gastrectomy was about 1%; in this population study the use of tri-staple technology for duodenal resection was mandatory. In our clinical practice, the incidence of DSF after open gastrectomy is about 3-5% adopting different techniques of duodenal stump resection/closure.
The aim of this study is to evaluate if duodenal stump resection/closure using tri-staple technology can significantly decrease the incidence of DSF after open gastrectomy as compared to the other conventional methods adopted in the clinical practice (1% vs 5%).
We have designed a national multicentre pragmatic (20) RCT to compare the use of endoGIA or Echelon (triStaple technology) to other conventional methods (GIA with or without manual reinforcement , manual suture, purse string) for duodenal resection/closure during open gastrectomy, with the assumption that Tri-staple technology without reinforcement ( as routinely used in LADG) is the safest method.
AIM OF THE STUDY The goal of this trial is to demonstrate that the use of Tri-Staple Technology for duodenal resection during open gastrectomy for cancer is safer than the use of other conventional methods of resection/closure of the duodenum and that the incidence of duodenal fistula can be decreased to that observed after the use of this technology in Laparoscopic and robotic gastrectomy, therefore almost three times lower than that currently reported in literature.
Participating centres must have an annual volume of at least 20 gastrectomies per year.
Design of the study This is a multicentre randomized controlled trial.
Patients with malignant tumor of the stomach, as primary diagnosis, requiring distal or total gastrectomy without anastomosis with the duodenum will undergo clinical preoperative workout and anaesthesiologist evaluation. All patients who meet the inclusion/exclusion criteria and agree to sign the informed consent are registered into the trial and randomized to one of the two arms (a. Duodenal Stump Closure with TriStaple Technology - TST or b. Duodenal Stump closure with other conventional techniques - OCT ) as described in the chapter Randomization. In TST arm no manual reinforce of the mechanical suture should be perfomed; in OCT group, a manual reinforce of the suture can be done according to the preference of the operator, and recorded in the trial data base (DB).
Patients' postoperative course will be carefully monitored and all variables detailed below will be recorded in the DB.
DSF will be diagnosed by the presence of duodenal fluid in the surgical drainage and confirmed by a CT scan when needed (presence of intra-abdominal peri-duodenal collection of fluid and/or micro air bubbles).
Also the type of treatment (conservative, percutaneous drainage, reoperation, others ) of DSF should be recorded, as well as the length of hospital stay and other postoperative complications or in-hospital death ( as well as 30- and 90- days mortality)
Trial setting
This is an Italian national multicentre RCT; the Division of General Surgery from University of Turin, Department of Surgical Sciences, AOU San Luigi Gonzaga di Orbassano, will be the Coordinating Centre of the trial. The P.I. of the trial is Prof Maurizio Degiuli.
S.S.D. Epidemiologia, Clinica e Valutativa, AOU Città della Salute e della Scienza di Torino, will be responsible for this trial's central randomisation and statistical analysis.
Clinical monitoring and data managing will be performed by the P.I. and and co-investigators.
Study population
inclusion criteria
pathologically proven malign tumor of the stomach age of 18 to 80 years, no history of other cancers no history of radiotherapy in supra-mesocolic space total or distal gastrectomy without anastomosis with the duodenum
exclusion criteria
emergency surgery American Society of Anesthesiologists class \> 3 need for combined resection of other organs laparoscopic/robotic access severe heart disease liver cirrhosis T stage \>cT4a citology positive at preoperative laparoscopy cM+ cD+
All patients freely give informed consent to participate in the study prior to surgery, at the time of discussing the intervention with the surgeon or the nurse and can decide to withdraw from the study at any time.
Diagnosis of DSF
A diagnosis of DF is made on the basis of the presence of duodenal juice in the surgical drainage or its leakage through the abdominal wall, and confirmed by CT scan and/or fistulography.
Variables
sex age ASA score COPD type 2 DM multiple comorbidities pre-operative albumin serum levels pre-operative lymphocytes blood count cT Stage / pTStage pTNM distal margin involvement intraoperative blood loss lenght of hospital stay Type of gastrectomy TG vs DG type of reconstruction: ( BII vs RY) lymph node dissection: D1, D1+, D2, \> D2

Randomisation
All patients who meet the inclusion/exclusion criteria and give the informed consent to participate are registered into the central trial database and centrally randomized to one of the two groups (a. Duodenal Stump Closure with TriStaple Technology - TST or b. Duodenal Stump closure with other conventional techniques - OCT ).
Patients refusing recruitment are treated with usual care and contribute to the database a limited set of pre-defined information.
Result of randomisation is communicated to the surgical team at the time of their entrance in the surgical theatre.
Sample size calculation and statistical analysis
Assuming an alpha error at the 5% level and power 80%, a total of 700 patients (350 per arm) are required in order to recognise a true difference of 5% in (a) vs 1% in (b).
Assuming an average case volume of 20 patients per year and 60% acceptance rate, about 30 Centres recruiting for two years will need to be involved.
Cox regression with multivariable analysis will be performed
Data property
Results will be the property of Università degli studi di Torino and of the researchers involved in the conduction of the mulicentre project. A scientific committee will be constituted comprising a lead investigator from each of the Centres.
