Low Gas Pressure vs Standard Gas Pressure in Weight-Loss Surgery
Sponsor: Weill Medical College of Cornell University
Summary
During weight-loss surgery that is done using a robot, the surgeon needs to put carbon dioxide gas into the belly to lift the belly wall. This is done so the surgeon can adequately see all the body organs and operate safely. Many surgeons currently use a standard pressure of 15 mmHg (a unit to measure pressure). However, many patients find the use of this pressure to be painful after surgery. New research has shown that using a lower pressure with a device called "AirSeal" can safely reduce pain and lead to faster recovery after surgery. The goal of this clinical trial is to learn if using a lower gas pressure with the AirSeal device during weight-loss surgery, compared to standard gas pressure with conventional devices, helps adults feel less pain and recover faster. The study includes adults aged 18 or older having robotic weight-loss surgery (sleeve gastrectomy or Roux-en-Y gastric bypass) at New York-Presbyterian Hospital/Weill Cornell Medical Center. The main questions this clinical trial aims to answer are: 1. Does using lower gas pressure shorten the time people spend in the recovery room after surgery? 2. Does using lower gas pressure lead to less pain and reduce the need for pain medicine after surgery?

Interventions
AirSeal Robotic Solution
The experimental intervention is low-pressure pneumoperitoneum at 8 mmHg using the AirSeal Robotic Solution device. The AirSeal Robotic Solution (CONMED Corporation) is an FDA 510(k)-cleared carbon dioxide insufflation device that is indicated for use in robotic-assisted surgery. It consists of a console, tri-lumen filtered tube set, and access ports that function as valveless trocars. The console of the device is mounted on a cart and regulates carbon dioxide flow and smoke evacuation by continuously measuring the intra-abdominal pressure. The trilumen filtered tube set carries carbon dioxide to the abdomen, transmits pressure information back to the console, and returns gas from the abdomen for smoke evacuation and filtration. These features allow for the device to operate in the "AirSeal" mode, whereby the pressure within the abdomen is effectively kept constant. The valveless trocars are access ports for the minimally invasive tools to enter the abdominal cavity.
Standard-pressure pneumoperitoneum (15 mmHg)
The control intervention is standard-pressure pneumoperitoneum set at a pressure of 15 mmHg. This will be delivered using the operating room's conventional valved-trocar carbon dioxide insufflator.
