[Laparoscopic excision of infected urachal remnant: a case report].

A 18-year-old man presented with fever and periumbilical nodule. Computed tomography (CT) showed complicated abscess of urachal remnant and laparoscopic surgery was performed transperitoneally via 3 ports. Laparoscopic excision of urachal remnant was first demonstrated in 1992 by Neufung et al, and in Japan first case was reported in 1998 by Ohmori et al. Some cases of laparoscopic surgery for urachal remnant were reported, but the surgical techniques, including port configuration, have not been standardized. In this case, we performed laparoscopic surgery with camera port in the umbilicus and two working ports in the bilateral positions. Our port configuration may be promising in ensuring good viewing during surgery and excising urachal remnant completely including umbilicus.
