ViSiGi® 3D Suction Calibration Device
The ViSiGi® 3D is the first calibration system specifically intended for use during sleeve gastrectomy.ViSiGi 3D®is a non-sterile, single patient use device. The device comprises a tube with a closed, rounded tip, and holes at the distal end. The proximal end of ViSiGi 3D® includes an integral suction regulator and vented On/Off valve. Advantages of ViSiGi® 3D device include simplification of sleeve calibration in addition to suctioning the stomach and performing leak tests all with one device making operative steps simpler for both the anesthesiology team and surgeons. Since it is single patient use it does not require reprocessing. ViSiGi® 3D suction calibration device: ViSiGi 3D®is a non-sterile, single patient use device.

Timeframe: During sleeve gastrectomy (up to 5 hours)

Population: Data for this study outcome was not collected due to internal limitations of the study.

Cost data (administrative data) will be retrieved from internal database

Outcome measures

Outcome data not reported

SECONDARY outcome

Timeframe: 1-2 months prior to surgery, 3 weeks post-operatively (+/- 2 weeks), 12 months post-operatively (+/- 12 - 24 months)

Population: Number of participants analyzed only included patients that were able to complete the questionnaire at each time point, which is different for each follow up.

GERD-HRQL questionnaire will be administered pre-operatively and post-operatively. The instrument contains a total of 10 scaled items which are scored, and a patient-reported global satisfaction assessment which is not added to the total GERD-HRQL score. Higher score correlates with worse outcome. Scale: No symptoms = 0; Symptoms noticeable, but not bothersome = 1; Symptoms noticeable and bothersome, but not every day = 2; Symptoms bothersome every day = 3; Symptoms affect daily activities = 4; Symptoms are incapacitating, unable to do daily activities = 5
