title: Preperitoneal herniation into a laparoscopic port site without a fascial defect.
abstract: BACKGROUND
  Port site herniation is an uncommon event that usually occurs as a result of incomplete fascial closure. This allows the omentum or viscera to herniate through the incompletely closed defect. However, in laparoscopic surgery for morbid obesity, the omentum and viscera can herniate through the thick preperitoneal space even with a complete closure of the fascia.
  
  
  METHODS
  A 19-year-old female with BMI 55 underwent uneventful long limb laparoscopic Roux-en-Y gastric bypass. On postoperative day 1 the patient had limited pain, was ambulating well, and was tolerating slps of liquids. A limited upper GI series performed on postoperative day 2 revealed no leak or obstruction. Several hours later the patient developed abdominal pain associated with nausea, which progressed to vomiting. CT of the abdomen suggested a port site herniation into the left subcostal port. The cause of the obstruction appeared to be herniation through the left subcostal port site. At laparotomy, a segment of bowel just distal to the anastomosis was found herniated through the port site. The Richter's hernia was reduced. Careful inspection of the fascia revealed a complete fascial closure, with the strangulated portion of the bowel incarcerated in the preperitoneal space. Following repair of the preperitoneal defect, her subsequent recovery was unremarkable.
  
  
  CONCLUSIONS
  Laparoscopic surgery for morbid obesity presents the possibility for preperitoneal herniation. Closure, using a fascial closure device, under laparoscopic control, may offer a solution by closing both the fascia and peritoneum all at once.
