A nationwide analysis of laparoscopic complications.

OBJECTIVE: To evaluate the nationwide incidence of laparoscopic complications, as the number of demanding gynecologic laparoscopic procedures increases worldwide.

METHODS: The National Patient Insurance Association was founded in 1987 in Finland. All major complications are reported to the Association because it handles financial compensation for patients' injuries without proof of malpractice. We analyzed 256 complications following laparoscopic procedures occurring in 1990-1994. There were 160 minor complications, which were defined as mild infections, mild hemorrhages, and failed sterilization. In all, 96 major complications occurred, including intestinal, urinary tract, and vascular injuries. The number of gynecologic laparoscopies (70,607 procedures) was obtained from the Finnish Hospital Discharge Register.

RESULTS: The total complication rate was 3.6/1000 procedures, and the rate of major complications was 1.4/1000 procedures. In diagnostic laparoscopies, the annual major complication rate was constantly below 0.6/1000, and in sterilization, it was below 0.8/1000. In operative laparoscopies, major complications increased from 0/1000 in 1990 to 10.5/1000 in 1993 and leveled to 10.1/1000 in 1994. In all, intestinal injuries occurred in 0.6/1000, ureteral injuries in 0.3/1000, bladder injuries in 0.3/1000, and vascular injuries in 0.1/1000 laparoscopic procedures.

CONCLUSIONS: Diagnostic and sterilization laparoscopies appear to be safe, but more complex laparoscopies are associated with an unacceptably high number of serious complications requiring continuous follow-up and expertise.
