Carbon Dioxide Versus Air Insufflation for the Application of Argon Plasma to Reduce the Gastrojejunal Anastomosis

Obesity Clinical Trial

Official title:
A Multicenter Randomized Clinical Trial of Carbon Dioxide (CO2) Versus Air Insufflation for the Application of Argon Plasma to Reduce the Gastrojejunal Anastomosis in Individuals With Weight Regain After Bypass Surgery.

Clinical Trial Summary

The objective of this randomized clinical trial is to compare pain levels during and after insufflation with carbon dioxide or in subjects that will undergo endoscopic fulguration with argon to reduce the diameter of the gastrojejunal anastomosis. The investigators hypothesize that carbon dioxide will be superior in causing less pain and leading to less discomfort.

Clinical Trial Description

Laparoscopic gastric bypass surgery is one of the strategies oriented towards weight reduction in obese patients. Although in the short term it has a high degree of success, weight regain is common in the long term, in part due to the dilatation of the anastomosis that allows food to pass without barriers and hinders the purpose of bypass surgery. Fulguration with argon is an endoscopic technique that reduces the diameter of the anastomosis, offering resistance to food passage and improving patient outcomes. Although carbon dioxide is the current standard for laparoscopic surgery, its use for fulguration with argon as compared to ambient air has not been investigated in the setting of the stenosis of a dilated anastomosis following gastric bypass surgery. stenosis. Therefore, to investigate pain during and after this procedure, investigators will conduct a randomized clinical trial comparing carbon dioxide and ambient air. The secondary aims will be to measure the diameter of the gastrojejunal anastomosis during three endoscopic sessions and in a final control examination eight weeks after the third session; to determine whether the patient loses weight or not by the final control objective after three sessions of endoscopic fulguration with argon; to analyze if the method employed is able to reduce body weight to the minimum weight achieved after bariatric surgery;and to investigate whether there is a correlation between the percentage reduction in anastomotic diameter and the percentage loss of regained weight. ;
