The Use of PrimeSight Transnasal Endoscopy in Bariatric Patients

Doctor with Weight Loss PatientThere will come a time during your patient’s weight loss journey where you, as the physician, will need to see the inside of their esophagus and stomach. Endoscopy plays a pivotal role in the bariatric surgery process because endoscopes allow physicians to view important anatomy from the patient’s throat to their stomach. You may want to see inside the patient’s body prior to surgery to determine the best options for the patients or to track the progress within a patient’s body post-surgery. 

In the past, EGD was the go-to method for upper endoscopy procedures, but now there is a less invasive and convenient option. PrimeSightTM Transnasal Endoscopy (TNE) provides a more simple procedure that benefits the patients and the physicians.

Before PrimeSight, There was EGD

Historically TNE, the primary viewing the anatomy from the throat to the stomach was an EGD Procedure, also known as Upper Endoscopy. The EGD exam requires the patient to undergo conscious sedation, which means a trip to the hospital or surgery center, a day off from work, and someone to drive them home once the exam is complete. Now, with the well-developed TNE procedure, sedation is no longer required, and it only takes about five minutes, unless a biopsy is required. This new exam has been simplified with a small, thin endoscope allowing the physician to have easy access transnasally without the difficulties associated with sedation. More importantly, TNE provides rapid results with an immediate visual review for the physician and patient.

PrimeSight Procedure Details

Preparing for a TNE is quite simple. The patient will be asked to not eat or drink anything for at least three to four prior to the procedure. This allows the physician to clearly see the anatomy without any obstructions, like the patient’s scrambled eggs they had for breakfast. The exam itself is fairly simple. First the physician administers a local topical anesthetic to the patient’s nose, numbing the area prior to the exam. Then, a small and thin endoscope is inserted through the nose and esophagus, and down into the stomach. While this procedure is taking place, the patient will be able to swallow and breathe without assistance, they may be able to speak to their physician as the exam is being performed. The physician also gets the added benefit of an active patient, allowing them to instruct them when to swallow and when to reposition their body when necessary.

Benefits of EndoSheath

The PrimeSight TNE System is used with the EndoSheath® Protective Barrier making it easy for Bariatric practices to incorporate in-office endoscopic examinations of bariatric patients, typically with a single PrimeSight TNE system and without investing in expensive reprocessing equipment. Throughout the TNE procedure, the EndoSheath Protective Barrier isolates the TNE scope from the patient. As a result, there is no need for HLD between procedures and the scope can be quickly prepared for the next patient in less than 10 minutes.

The Use of PrimeSight TNE in bariatric patients is a practice-enhancing opportunity for the practice, and a time-saving measure for patients. But more importantly, it ensures patients receive optimal care throughout the treatment continuum.  PrimeSight is safe and simple allowing you to visualize a patient’s upper airway, esophagus, and stomach area with its immediate and rapid visualization for pre and post-operative patients.
