Study Summary

This trial is testing whether lower pressure pneumoperitoneum during laparoscopic large bowel surgery protects the bowel from postoperative ileus and bowel dysfunction, leading to faster recovery and discharge from the hospital.

Who is the study for?
Adults over 18 needing laparoscopic surgery for large bowel issues like tumors or polyps can join. They must agree to participate and not have inflammatory bowel disease, past major abdominal surgeries (except appendectomies/hernia repairs), conditions affecting drug metabolism, significant other illnesses, certain pre-surgery imbalances, a history of intestinal adhesions, or allergies to specific drugs used in the study.Check my eligibility
What is being tested?
The trial is testing if using lower pressure inside the abdomen during surgery leads to quicker recovery from postoperative ileus (bowel paralysis) and gastrointestinal dysfunction. It compares high vs low pressures with different devices that control this pressure during laparoscopic bowel resections.See study design
What are the potential side effects?
Possible side effects may include discomfort at insufflation sites, variations in blood pressure or heart rate due to changes in abdominal pressure, pain after surgery related to gas insufflation technique used, and potential reactions to neuromuscular blockade reversal agents.

Trial Design

5Treatment groups
Experimental Treatment
Active Control
Group I: Arm 3B: AirSeal® Pneumoperitoneum and Deep BlockadeExperimental Treatment4 Interventions
25 patients undergoing laparoscopic right hemi-colectomies or sigmoid resections using low pneumoperitoneum pressure with AirSeal® TM system under deep neuromuscular blockade with rocuronium and neuromuscular blockade reversal with sugammadex. In addition, clinical data on postoperative ileus will be correlated with experimental outcomes from in vitro exploratory studies done using human samples of peritoneal lavage fluid, serum, and a small portion of the surgically removed bowel from each patient (that is otherwise discarded). A panel of inflammatory markers will be analyzed and biochemical, imaging, histological, immunochemical, molecular signaling, and glial activation studies will be done to evaluate the potential mechanisms of dysfunction associated with postoperative ileus.
Group II: Arm 3A: Conventional Pneumoperitoneum and Deep BlockadeExperimental Treatment4 Interventions
25 patients undergoing laparoscopic right hemi-colectomies or sigmoid resections using low pneumoperitoneum pressure with conventional insufflation under deep neuromuscular blockade with rocuronium and neuromuscular blockade reversal with sugammadex. In addition, clinical data on postoperative ileus will be correlated with experimental outcomes from in vitro exploratory studies done using human samples of peritoneal lavage fluid, serum, and a small portion of the surgically removed bowel from each patient (that is otherwise discarded). A panel of inflammatory markers will be analyzed and biochemical, imaging, histological, immunochemical, molecular signaling, and glial activation studies will be done to evaluate the potential mechanisms of dysfunction associated with postoperative ileus.
Group III: Arm 2B: AirSeal® Pneumoperitoneum and Moderate BlockadeExperimental Treatment4 Interventions
25 patients undergoing laparoscopic right hemi-colectomies or sigmoid resections using high pneumoperitoneum pressure with AirSeal® trademark (TM) system under moderate neuromuscular blockade with rocuronium and neuromuscular blockade reversal with sugammadex. In addition, clinical data on postoperative ileus will be correlated with experimental outcomes from in vitro exploratory studies done using human samples of peritoneal lavage fluid, serum, and a small portion of the surgically removed bowel from each patient (that is otherwise discarded). A panel of inflammatory markers will be analyzed and biochemical, imaging, histological, immunochemical, molecular signaling, and glial activation studies will be done to evaluate the potential mechanisms of dysfunction associated with postoperative ileus.
Group IV: Arm 2A: Conventional Pneumoperitoneum and Moderate BlockadeExperimental Treatment4 Interventions
25 patients undergoing laparoscopic right hemi-colectomies or sigmoid resections using high pneumoperitoneum pressure with conventional insufflation under moderate neuromuscular blockade with rocuronium and neuromuscular blockade reversal with sugammadex. In addition, clinical data on postoperative ileus will be correlated with experimental outcomes from in vitro exploratory studies done using human samples of peritoneal lavage fluid, serum, and a small portion of the surgically removed bowel from each patient (that is otherwise discarded). A panel of inflammatory markers will be analyzed and biochemical, imaging, histological, immunochemical, molecular signaling, and glial activation studies will be done to evaluate the potential mechanisms of dysfunction associated with postoperative ileus.
Group V: Arm 1: Standard of CareActive Control1 Intervention
25 patients undergoing laparoscopic right hemi-colectomies or sigmoid resections using high pneumoperitoneum pressure with conventional insufflation under moderate neuromuscular blockade with rocuronium and neuromuscular blockade reversal with neostigmine. In addition, clinical data on postoperative ileus will be correlated with experimental outcomes from in vitro exploratory studies done using human samples of peritoneal lavage fluid, serum, and a small portion of the surgically removed bowel from each patient (that is otherwise discarded). A panel of inflammatory markers will be analyzed and biochemical, imaging, histological, immunochemical, molecular signaling, and glial activation studies will be done to evaluate the potential mechanisms of dysfunction associated with postoperative ileus.

Frequently Asked Questions

These questions and answers are submitted by anonymous patients, and have not been verified by our internal team.

Are there opportunities for enrolment in the current clinical trial?

"According to clinicaltrials.gov, the patient recruitment period for this medical trial has already concluded; it was initially posted on December 30th 2022 and last updated on September 14th 2022. Nonetheless, there are currently 35 other similar studies actively seeking participants."

Answered by AI

What are the hoped-for end results of this research?

"This clinical trial seeks to measure postoperative gastrointestinal tract (GIT) function recovery over a period of up to 30 days from the end of surgery. Secondary outcomes include the time taken for participants to experience their first bowel movement and flatus after surgery, as well as calculate the number with delayed postoperative ileus defined by an inability to consume solid foods, take anything orally or require nasogastric tube insertion past day five."
