[Does the laparoscopic technique influence the intraperitoneal tumor dissemination?].
Rapid tumour growth after laparoscopic surgery is a rare and mysterious problem. In seven years period (October 1992-31 June 1999) in the 2nd Department of Surgery at the Jagiellonian University in Cracow, we observed seven persons (five women and two men aged 45 to 70 years), who in short time after laparoscopic cholecystectomy, developed intra-abdominal cancer dissemination. In all cases before and during the operation gallbladder was unsuspected. In five patients, gallbladder cancer (T3) was found in routine postoperative microscopic examination. 18 to 65 days after laparoscopic cholecystectomy patients were operated on and in all cases reexcision was impossible because of micronodular tumour dissemination in peritoneal cavity. The next woman, six months after laparoscopic cholecystectomy, gastric cancer was diagnosed, and during the operation we found intraperitoneal micro-nodular tumour growth. Last patient 4 months after laparoscopic hernioraphy and cholecystectomy had pancreatic cancer subsequently portsite metastasis and intraabdominal cancer dissemination.


CONCLUSIONS
Rapid tumour dissemination in peritoneal cavity after laparoscopic cholecystectomy is probably a consequence of laparoscopic technique.
