title: [Neoplastic residues in the trocar tract in oncologic laparoscopic surgery].
abstract: OBJECTIVE
  The laparoscopic approach to malignant diseases runs up against both old and new problems: respect for the principles of radicality, operating times, the postoperative course and surgical complications, long-term oncological results in terms of survival and recurrence of the disease. One of the problems which has received most attention regards the onset of a metastasis on a trocar scar or a mini-laparotomy recurrence. Trocar site tumor recurrences have been described in the literature following laparoscopic surgery in almost all abdominal malignant pathologies (colorectal, gynaecological, pancreatic, etc.) and even after thoracoscopy. The real frequency is currently of the order of 1% (0-2%) in colic surgery and of 14% (10-17%) after cholecystectomy for occult gallbladder carcinoma.
  
  
  METHODS
  A retrospective survey was carried out of our laparoscopic experience; between 1994 and 2002 213 colic resections were carried out for cancer; we also observed 18 occult carcinomas of the gallbladder in 2386 laparoscopic cholecystectomies for lithiasis.
  
  
  RESULTS
  Respectively 2 cases (11%) of trocar site neoplastic recurrences in gallbladder carcinoma and 2 cases (0.9%) from colon carcinoma were observed.
  
  
  CONCLUSIONS
  The real extent of the problem would appear to be on a much lesser scale at the moment than was initially thought, especially as regards colic surgery. The multifactorial aetiology of the problem explains the importance of their prevention, on the basis above all of rigorous respect for the rules and protocols of laparoscopic technique.
