Summary
Converting a 5-mm laparoscopic port to a larger 10- or 12-mm port is safely achieved using a blunt conical trocar. This cost-effective technique minimizes risks associated with sharp trocars during operative laparoscopy.
Area of Science:
- Minimally Invasive Surgery
- Laparoscopic Techniques
- Surgical Instrumentation
Background:
- Large ancillary ports (≥10 mm) are frequently used in operative laparoscopy for instrumentation and tissue removal.
- Sharp pyramidal trocars for placing large ports may increase risks of vessel injury and herniation.
- A novel technique using a blunt conical trocar is presented to safely convert smaller ports to larger ones.
Purpose of the Study:
- To describe a simple, cost-effective method for converting a 5-mm laparoscopic port to a 10- or 12-mm port.
- To evaluate the safety and efficacy of using a blunt conical trocar for port site expansion.
Main Methods:
- A 5-mm port is removed, and the skin incision is lengthened.
- A reusable 10- or 12-mm blunt conical trocar is inserted through the incision.
- The fascial defect is dilated with the blunt tip and advanced through the peritoneum using a twisting motion, followed by fascial closure.
Main Results:
- The technique was successfully employed in 26 cases without any reported complications.
- No intraoperative or postoperative difficulties were encountered during port site conversion.
Conclusions:
- A reusable blunt conical trocar provides a safe, simple, and cost-effective solution for expanding laparoscopic port sites.
- This method offers a reduced risk profile compared to sharp trocars for creating larger port access.
