Study to Assess the Effectiveness of Transcollation Technology to Reduce Bleeding in Lung Surgery
A Prospective, Randomized, Controlled Study to Assess the Effectiveness of Transcollation Technology to Reduce Bleeding in Lung Surgery
Major lung resection is one of the most common procedures performed in thoracic surgery, but it may involve considerable bleeding and the occasional need for a transfusion and/or reoperation for bleeding in specific cases. In addition, lysis of pleural-parenchymal adhesions and dissection can represent a challenge in patients who have undergone chemotherapy and/or radiation therapy, and in patients with bronchiectasis or COPD. Several intraoperative methods have been used to manage blood loss, including topical haemostatic agents, bipolar sealers or electrocautery. Transcollation technology (TT) consists of a disposable bipolar sealer that uses a radiofrequency coagulation system to deliver a saline solution that provides haemostatic sealing of soft tissue and bone and provides localized cooling without charring. Blood loss reduction has been previously described in several fields of surgery.
The primary end-point of the proposed trial is to assess if the ability of Transcollation Technology in reducing the proportion of patients showing bleeding perioperatively within the setting of a prospective randomized controlled trial.
The secondary end-point is to assess if Transcollation Technology is able to improve postoperative outcomes reducing the length of hospital stay.

Detailed Description
Study participation will start at signature of informed consent and each subject will be assessed preoperatively, within 4 weeks before surgery. A patient information leaflet will form the basis of discussions with the patient before written informed consent is obtained.
Patients will be evaluated intra-operatively, at 24 and 48 hours after surgery, and at discharge.
At the preoperative visit, the following information will be recorded on the patient's Case Report Form by a specialist Registrar:
- Patient number
- Patient initials
- Date of visit
- Demography (date of birth, sex, height, and weight)
- Preoperative FEV1 and % predicted FEV1
- Co-morbidities (chronic obstructive pulmonary disease [yes/no], current smoking habit [yes/no])
- levels of hemoglobin (preoperative, postoperative, 24 h, 48 h and discharged)
- perioperative complication.
Interventions
Patients undergoing Major Lung Surgery will be randomly assigned to one of two management strategies before the starting of the operation:
- Electrocautery Using routine instrument for hilar dissection, hemostasis and lisys of eventual pleural adhesions.
- Transcollation Technology Using Transcollation Technology for hilar dissection, hemostasis and lisys of eventual pleural adhesions.
Randomization Patients will be randomized in a 1:1 ratio to Transcollation technology (TT) or electrocautery. Patients will be allocated to the two different groups following a block randomization with sealed envelopes. This study is open-label: patients, investigators.
Allocation concealment The nature of the treatment precludes blinding of the surgeon administering the intervention. However, allocating, monitoring and measurement of all primary and secondary endpoints will be made by a dedicated investigator without the knowledge of, or reference to, the treatment allocation (electrocautery or Transcollation technology).
A dedicated investigator will provide a series of sealed envelopes, each containing a randomized treatment allocation. The operating surgeon will ascertain the treatment allocation for each eligible patient by opening the next available sealed randomization envelope. For each patient, the opened envelope will be attached to the Case Report Form for statistical analysis.
Sample Size Group sample sizes of 77 and 77 achieve 90% power to detect a difference of 65,0 ml of chest drain fluid at 24 h between the null hypothesis that both group means of chest drain fluid are 425,0 ml and the alternative hypothesis that the mean of group 2 is 360,0 ml with known group standard deviations of 124,0 ml, with a significance level (alpha) of 0,05 using a two-sided two-sample t-test. We consider a 10% of drop-out then we will recruit 170 patients.
