[Pre-peritoneal bisaccular umbilical and subcutaneous abscess after laparoscopic appendectomy]

Laparoscopic surgery has gained much interest since its advent the late eighties. A 36-year-old patient underwent laparoscopic appendicectomy via the transumbilical route. She was rehospitalized three times thereafter for subumblical pain. At day +48, an abscess was evacuated at the point of the umbilical trocar insertion. This hour-glass shaped abscess had a preperitoneal and subcutaneous localization, blocked by the epiploic reaction. The infection this patient developed is an unusual clinical finding as pain was localized at a distance. The umbilical site and the preperitoneal subcutaneous nature of the abscess are also unusual. This case emphasizes the gravity of post-operative abscess of the abdominal wall and the necessity for adequate prophylaxy.
