Post-Operative Outcomes of Low Thermal Dissection vs. Traditional Electrosurgery

Pilot Study: Post-Operative Outcomes of Low Thermal Dissection vs. Traditional Electrosurgery for Mastectomy Breast Flap Creation With Immediate Breast Reconstruction

Low thermal dissection devices have been introduced as a tool to improve surgical outcomes. PlasmaBlade, a low thermal dissection device, has shown to be associated with effective cutting, and significantly lower temperature than traditional electrosurgical dissection device. Thus, low thermal devices would improve flap perfusion by decreasing the thermal injury resulted by the dissection. Looking into the use of low thermal devices in cases of mastectomy and immediate breast reconstruction has not been documented. The aim of this study is to determine if there are clinical flap perfusion, surgical site drainage, and pain scores differences between mastectomy flaps created using low thermal dissection device and those done with the standard care of Bovie cautery in order to warrant a formal study.

研究概览

详细说明

This is a single-blinded, randomized, controlled clinical trial comparing postoperative flap perfusion and surgical site drainage between patients randomized to breast flap creation by PlasmaBlade (low thermal dissection intervention) on one breast and by a Bovie cautery (Control) for the contralateral breast flap. Candidates will have elected to undergo bilateral post-mastectomy immediate breast reconstruction (IBR). Participants meeting inclusion criteria will be enrolled and baseline data collection completed prior to randomization and surgery.

Patients and the plastic surgeon will be blinded in regards to intervention randomization. Only the oncology surgeon has knowledge of which device used for each breast flap. However, after the plastic surgeon makes the assessment of the flap, he/she will be unblinded in order to complete the reconstruction procedure using the same dissection device on the same side it was used for in the mastectomy procedure. Patient-specific surgical details will be recorded intraoperatively. Following the surgery, post-operative flap perfusion will be recorded using SPY imaging system. Surgical site drainage will be measured until drainage removal. Post-operative pain (Visual Analog Scale for Pain) and the occurrence of adverse events will be recorded up until discharge and 30-days postoperative follow up visit.

武器和干预

参与者组/臂
干预/治疗
实验性的:Breast flap creation with PlasmaBlade
During participant's scheduled bilateral mastectomy, breast flap on one breast will be created using low thermal dissection device (PlasmaBlade) on one breast and standard Bovie cautery in the contralateral breast.
PlasmaBlade (Medtronic) is approved by United States Food and Drug Administration (FDA) as a low thermal dissection device that has shown to be associated with effective cutting, and significantly lower temperature than traditional electrosurgical dissection devices.
无干预:Breast flap creation with Bovie Cautery
During participant's scheduled bilateral mastectomy, breast flap will be created using standard Bovie cautery on the breast contralateral to the one that was created using PlasmaBlade.

研究衡量的是什么?

主要结果指标

结果测量
措施说明
大体时间
Perfusion
大体时间:Day of Surgery
Plastic surgeon objectively assesses degree of perfusion with the SPY Perfusion Assessment system (intra-operative fluorescence imaging system). Plastic surgeon describes perfusion as Left better than Right, Right better than Left, or both sides equally perfused.
Day of Surgery

次要结果测量

结果测量
措施说明
大体时间
Drainage
大体时间:Up to 14 days post-operatively.
Patient records amount of drainage (in cc's) from each drain until drain is removed by plastic surgeon.
Up to 14 days post-operatively.
Pain Scores
大体时间:Days 1,2,3,7,30 Post-operatively
Patient records pains scores using Visual Analog Scale (10cm long line upon which patients indicates level of pain)for each side at Day 1, 2, 3, 7, and 30. Scores range from 0-10. Score of 0 corresponds with 0 cm on the line and 10 corresponds with 10cm on the line. 0 indicates no pain and 10 indicates most severe pain.
Days 1,2,3,7,30 Post-operatively
