A simple and reliable procedure for laparoscopic port-site closure



One of the complications in laparoscopic surgery is port-site hernia. It is a rare but potentially dangerous complication. Especially when using ports with a size 10 mm or more, it is required to securely close the port site. However, this procedure is often difficult especially for obese patients.


We herein devised a new closure method by using a device developed for port site. These techniques are methods that can close the port site by a combination of putting in and out of thread and port rotation without removing a port. The port-site closure with these techniques was done for 53 port sites of 41 patients.


The port site was closed horizontally or vertically, depending on the shape of the port site for two patients. Modified Z-suture was done for other 37 patients. To date, we have not noted any complications from this new method, including port-site hernia.


With our technique, we could save operation time and reduce stress of us especially for obese patients. We would like to increase the number of patients and verify the safety and usefulness in further study.
