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.

Conditions

  • Dilatation of Anastomosis
  • Bypass Complication
  • Obesity

Interventions

DRUG

Carbon dioxide

Carbon dioxide will be used as an insufflating gas during argon fulguration of the dilatated anastomosis.

DRUG

Ambient air

Ambient air will be used as an insufflating gas during argon fulguration of the dilatated anastomosis.

DRUG

Argon fulguration

The dilatated anastomosis from the gastric bypass surgery will be reduced in diameter using fulguration with argon. Patient in both groups will be placed in the left lateral decubitus position, with anesthesia being performed exclusively using propofol; adequate cardiopulmonary monitoring will be carried out during the entire procedure. After sedation, endoscopy will be performed with an Olympus CV-180 endoscope (Olympus, Tokyo, Japan) and analysis and measurement of the anastomosis will be achieved using Raptor foreign body forceps (Endoscopy Group US, Inc., Mentor - Ohio, USA). The images will be transferred to an Olympus EvisExera II processor connected to a computer with the ZScan 5 program (Goiânia, GO, Brazil).
