Endoscopic Procedures IV: Sigmoidoscopy and Laproscopy

Endoscopic Procedures IV: Sigmoidoscopy and Laproscopy

Sigmoidoscopy and laparoscopy are distinct medical procedures that enable physicians to internally inspect different parts of the GI tract. Although they serve different purposes, each is essential for diagnosing and, in some cases, treating various medical conditions.
Sigmoidoscopy
Sigmoidoscopy is a diagnostic procedure that uses a flexible sigmoidoscope equipped with a light source and camera to examine the rectum and sigmoid colon. The procedure involves inserting the tube through the anus...

Transanal endoscopic microsurgery (TEM) pioneered single port surgery (SPS). Researchers developed new instruments for transvaginal single port laparoscopic surgery, tested in a cholecystectomy model, offering enhanced precision.

Area of Science:

Minimally Invasive Surgery
Surgical Technology Innovation

Background:

Transanal endoscopic microsurgery (TEM) established single port surgery (SPS) in colorectal procedures.
Single port surgery offers advantages over multi-port approaches.
Existing flexible technologies lack precision in minimally invasive surgery.

Purpose of the Study:

To develop novel instruments and a system for transvaginal single port laparoscopic surgery.
To evaluate the safety and efficacy of the new transvaginal SPS system.
To compare the precision of new rigid instruments with current flexible technologies.

Main Methods:

Development of specialized instruments for transvaginal access and manipulation.
Creation of a single port system for laparoscopic procedures.
