Endoscopic vs. Suction Device Calibration in Sleeve Gastrectomy

Not Applicable

Completed

Interventions: Device: Esophagogastroduodenoscopy (EGD) calibration
Device: ViSiGi® 3D suction calibration device

Brief Summary: This study aims to compare the difference in staple usage and post-operative GERD (heartburn) between patients that had an endoscope used versus patients that had a suction calibration system used on them during "laparoscopic sleeve gastrectomy" (LSG).

Detailed Description: There are multiple choices for a surgeon and their patient when it comes to weight loss surgery. One of those options is a procedure called a "laparoscopic sleeve gastrectomy" (LSG). In this procedure the majority of the patient's stomach is removed leaving behind a stapled "sleeve" about the same size as the patient's esophagus.

During this procedure there are three main devices that surgeon inserts through the mouth and in to the stomach to calibrate the size of the "sleeve". They can use a standard weighted bougie, an endoscope, or a suction calibration device. This study aims to compare the difference in staple usage and post-operative GERD (heartburn) between patients that had an endoscope used versus patients that had a suction calibration system used on them during LSG.

Arm && Interventions

Group	Intervention	Description
Esophagogastroduodenoscopy (EGD) calibration	Esophagogastroduodenoscopy (EGD) calibration	Gastroscope, similar to The ViSiGi device, have suction, calibration, and leak testing capabilities.
ViSiGi® 3D suction calibration device	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.

Primary Outcome Measures

Name	Time	Method
Number of Staple Load Firings	During sleeve gastrectomy (up to 5 hours)	Staple usage will be recorded during the weight loss surgery procedure.

Secondary Outcome Measures

Name	Time	Method
Body Weight	3 weeks post-operatively (+/- 2 weeks), 12 months post-operatively (+/- 12 - 24 months)	Total body weight was calculated in Kg.
Intra-operative Cost for Patients	During sleeve gastrectomy (up to 5 hours)	Cost data (administrative data) will be retrieved from internal database
Operative Duration (Time)	During sleeve gastrectomy (up to 5 hours)	Surgery start and completion time will be recorded, and operative duration will be calculated
GERD Symptom Severity Score	1-2 months prior to surgery, 3 weeks post-operatively (+/- 2 weeks), 12 months post-operatively (+/- 12 - 24 months)	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
