Evaluation of Ability to Detect Bowel Gas During Laparoscopic Right Colectomy With Intracorporeal Anastomosis
NCT04964297 · Status: TERMINATED · Phase: NA · Type: INTERVENTIONAL · Enrollment: 3
Last updated 2025-06-06
Summary
Undetected bowel perforation is a rare but dangerous complication of laparoscopic surgery. If the injury is not detected and treated at the time of the surgical procedure, the patient can suffer severe complications, including septic shock and eventually death. The investigator's goal is to test a novel device that can detect bowel gas leakage from perforation and alert the surgeon during the operation by evaluating the gases present in the insufflated abdomen during surgery. This study will determine the ability of the device to be attached to a standard trocar during the operation and periodically draw small samples or aliquots of gas from the abdomen to evaluate the gas and accurately detect gaseous content from the bowel. Before the device can be used to detect bowel perforations, the investigators must first ensure that it can accurately detect bowel gas in an insufflated abdomen.
Conditions
- Crohn's Disease of Large Intestine
- Malignant Neoplasm of Colon
Interventions
- DEVICE
-
Obtaining bowel gas samples
The Perf-AlertTM prototype consists of a 15" x 13" x 7" unit containing gas sensors and valves, a small box containing a one-way, ultra-low pressure pump, user controls (buttons), and software algorithms, which control the operation of the device. It is used in conjunction with a single-use, disposable kit of sterile tubing and filters used for sample collection. The sensing unit will be connected via a sterile tube/filter set to any trocar port in use during the procedure. At specific time points during surgery, a one-way valve will be opened, and the unit's pump turned on and withdrawing a small amount of gas from the abdominal cavity. The system is configured that sample collection, transport, analysis, and feedback occur in a single step such that sample collection and sensor feedback occur in real-time. A standard laptop running an analytical software program is connected to the unit to record and log sensor readings.
