Incarcerated hernia in a 5-mm cannula wound.

Laparoscopic suturing and repairing of the fascial opening at 10- to 12-mm cannula puncture sites is well established; however, closing a 5-mm cannula wound is not well documented. We often leave the wound open without suture and cover it with gauze after removing the surgical drainage tube. An unusual early postoperative complication of laparoscopic surgery was an incarcerated hernia in a 5-mm cannula site. The 9-year-old girl underwent laparoscopic surgery due to an 8-cm ovarian mature teratoma. After 7 days, she came to our hospital because of a protruding mass in the left cannula wound. The mass was excised, and incarcerated fallopian tube torsion with necrotic change was diagnosed.
