Impact of Intestinal Gas Emission Quality and Quantity on Recovery and Complications After Abdominal Surgery A Multicenter Prospective Observational Study

What this Trial Is About

Researchers are investigating how the quality and quantity of intestinal gas emissions relate to recovery after abdominal surgery and the occurrence of postoperative complications. The study focuses on patients undergoing open or laparoscopic abdominal surgery with a hospital stay expected to be at least two days. Intestinal gas emissions are considered a reflection of the gut microbiota, which may help predict surgical outcomes and complications. Participants will report data on their intestinal gas transit starting two days before surgery and continuing until hospital discharge or up to 15 days post-surgery if still hospitalized. Complications occurring within 90 days following surgery will be recorded, including during the hospital stay, at a 30-day postoperative consultation, and via a 90-day follow-up phone call. The study aims to compare pre- and postoperative gas quality and quantity and develop a predictive score for complications based on these observations. Participants will complete questionnaires daily about their gas emissions and stool characteristics before and after surgery. Researchers will collect and analyze data on postoperative complications and recovery progress over 90 days. This includes monitoring deviations from expected outcomes according to a standard classification. The total involvement may last up to approximately three months, with follow-up assessments conducted in person and by phone to evaluate recovery and complications.
