Methods and devices for detecting bowel perforation

Abstract

The present disclosure relates to methods and devices to detect perforation of the bowel, for example, resulting from surgical procedures, such as laparoscopy, diagnostic procedures, such as colonoscopy, medical conditions, such as diverticulitis, and trauma. The present disclosure also relates to filtration systems and electrical connector assemblies for use in the methods and devices.

AI Technical Summary

Benefits of technology

Enables timely detection of bowel perforations during surgical procedures, reducing the risk of delayed diagnosis and associated complications, and facilitating immediate treatment to minimize patient morbidity and mortality.

Problems solved by technology

The cost of reparation, as well as patient morbidity and mortality are far greater if a bowel perforation is not detected at the time of surgery.

Sepsis and septic shock can lead to hypoxia, renal failure, other major organ dysfunction and death.

This further increases the number and complexity of laparoscopic surgeries that are routinely performed.

Lack of surgeon feel, as well as reduced visualization associated with robotic assisted laparoscopic procedures can contribute to the risk of bowel perforation and decrease the possibility of immediate detection.

Bowel perforation injuries are a risk associated with laparoscopic surgery.

Bowel perforation injuries are not easily visualized by medical personnel during surgery due to optical limitations of the surgical equipment.

Because of the difficulty in visualizing bowel perforations at the time of injury, there is an increased chance that the injury will not be detected during the procedure leading to the above-described negative health effects and increased costs of treatment.

In addition to surgical bowel perforations, patients may suffer trauma or ruptured diverticula causing bowel perforations that are difficult to diagnose by CT scan and clinical examination.

Diagnosis relies on CT scans which can result in false negatives and clinical findings often present 24-28 hours after the onset of the infectious process.
