Summary
Establishing laparoscopic ports using the trocarless visual cannula (TVC) is feasible and reproducible. This method demonstrates high adoptability for gynecologic surgery, with minimal complications observed.
Area of Science:
- Minimally Invasive Surgery
- Gynecologic Surgery
- Surgical Technology
Background:
- Laparoscopic surgery requires safe and efficient establishment of peritoneal access.
- Traditional port placement methods can carry risks of injury.
- The trocarless and externally threaded visual cannula (TVC) offers a novel approach to port establishment.
Purpose of the Study:
- To evaluate the feasibility, reproducibility, and safety of using the trocarless TVC for laparoscopic port creation.
- To assess the adoption rate and potential complications associated with this technique.
Main Methods:
- A multicenter, prospective, observational study involving 4,724 women undergoing laparoscopic surgery.
- The trocarless TVC was used for port establishment after initial Veress needle insertion.
- Data on entry-related events and complications were collected and analyzed.
Main Results:
- The trocarless TVC was successfully used in the vast majority of cases, with high rates of umbilical and left upper quadrant entry.
- No serious abdominal wall or intra-abdominal vascular injuries were reported.
- One intraoperative injury to the transverse colon occurred, which was recognized and repaired.
Conclusions:
- Laparoscopic port establishment using the trocarless TVC is feasible, reproducible, and shows high adoptability.
- The technique appears safe, with a low rate of significant complications.
